Technical field

The present invention relates to the device and method for being respectively used to utilize carbon raw material, and further relate to raw material or by it The associated uses of the gas of recycling.More particularly it relates to using by can't be used in standard base at present or There is presently no the equipment of the recycling of (pair) product in the raw material production coke for generating satisfactory final products and sides by person Method.More particularly it relates to according to the device and method of the preamble of each independent claims.In addition, of the invention It is related to the particularly purposes of separate part relevant to these alternative materials or equipment.

Background technique

For the economy of most countries on our earth, coke and carbonaceous/carbon raw material are important basic material Material itself represents valuable material under its existing forms, is currently in this way, being in the future also in this way.So far, coking Mainly the bituminous coal (referred to as rich coal) with high-adhesion energy is carried out.However, in the near future, in world markets, Certain form of coke may become more rare.It especially must be it is contemplated that being very suitable for obtaining for the coking coal of coking Property will reduce, as a result, coal or other carbon sources using low caking property or high-expansion may be needed, also in the future with especially For producing blast-furnace coke.The reason of primarily for political pressure, in the future need to especially on the territory including Europe Will be particularly for the substitute of conventional bituminous coal, this is especially because burning raw material may be still in decades from now on as the energy It so keeps most important.In Europe, conventional coking coal was always treated as key raw material since 2014；However, and other Key raw material is compared, and still has maximum economic significance.In general, here it is readily apparent that on the one hand existing Contradiction, and on the other hand there is the chance or motivation for advanced optimizing measure being advantageously carried out since conventional coking process.

Currently, energy transition is more only carried out in the rich countries of intense industrialization, and based on many years/decades ago State-of-art, developing country will rely on the conventional conventional raw materials of burning within many years.Even however, for example Australia, particularly Queensland highly developed country, also have at present be converted to more modern furnace technology and future after The continuous high-level investment activity that can largely improve domestic raw material.Therefore, for following device and method, exist Very big interest and higher technical need, the device and method allow to provide new chance to produce or utilize coke or have The certain form of coke of the property of restriction or extension can be used for the range of the raw material of coke production.Naturally, pass through these Mode can also avoid the need for certain raw material in global long-distance transportation.

Special technological challenge is by weak caking property and inadherent coked material (especially including the raw material of lignite) Produce high-grade coke.It using such raw material in Europe is also likely to be to attract people's attention on the basis of widely, this is special The case where being due to compared to such as bituminous coal, such raw material still can be exploited under more acceptable cost approach. The present invention is more particularly directed to this challenge more outstanding is become in nearest period, so that also can use unconventional raw material.In It especially attracts people's attention herein, such as also using the raw material with high-sulfur fraction, this is particularly due to allow accurately will The various applications that the resulting sulphur is utilized as byproduct may become obvious.

It has been proved that in many cases, only when raw material or raw material are compressed in advance in a specific way and process (title It is briquetting/compacting of raw material to form coal agglomerate) when, conversion of the coal to premium coke is just successively performed.Agglomerate is typically desired The high pressure in the bed in furnace chamber is born, these height is several meters, especially in the case where large size perpendicular cavate furnace, and Agglomerate will be broken into little particle as much as possible.Therefore, the major criterion of advantageous technological design is also possible to accessible raw material Intensity, especially with respect to the use in perpendicular cavate furnace.Therefore, significant in the raw material and new method for finding new, substitution The problem of first is that the problem of the form processing of the raw material of substitution should be desirable to provide and how can carry out related processing.

As described above, the coking furnace for producing coke can take the form of so-called perpendicular cavate furnace.Perpendicular cavate furnace from Top loads raw material agglomerate or coal agglomerate.Perpendicular cavate furnace extends to comparable height, such as in 30 to 40m range It is interior.For example, agglomerate is placed on above furnace using crane, and slided especially by gravity, by coking well (furnace chamber), Especially by corresponding multiple hours time time needed for being converted into coke with raw material, such as 12 or 15 hours.In During this, agglomerate undergoes temperature change, especially from 300 DEG C of initial temperatures below to 900 DEG C to 1100 DEG C most Finishing temperature.Coking furnace generally includes the component with two to ten furnace chambers, forms so-called room.The well of corresponding furnace chamber can have Especially 3.5 to 10m height and especially 150 to 600mm width.Thus it is readily apparent that agglomerate is in coking period Between be subjected to high frictional force and pressure.Therefore, the intensity of agglomerate is as very high as possible.In addition, the present invention is can exist in agglomerate Volume change and " effective " mass transfer.Therefore, certain porosity is also advantageous.

In order to provide agglomerate, raw material can be crushed especially in advance in beater grinder, more particularly be crushed To 0 to 1mm granularity.Next, in general, agglomerate is compacted in press by the compression of particle, and exist so far In many cases, there is the agglomerate geometry of the alternately elongate pieces form at the edge at the angle or rounding of rounding to have had proved to be Benefit.The agglomerate of ellipsoid form be also it is common, produced especially through roll squeezer.

In order to improve crushing raw material adhesive property (viscosity of particle during and after compression), can add Water.Once high water content may have unfavorable consequence to the intensity of agglomerate, the result is that especially most however, agglomerate coking Big power or load acts in the lower area in the perpendicular cavate furnace on agglomerate, and agglomerate disintegrates and damages coking.

In fact it has been shown that will appear difficulty in different operating procedures in the whole process, especially work as group When the intensity of block is not high enough, the result is that coal/coke briquette is crushed in the bed in coking well.Therefore, in many cases, should The lower limit of the numerical value of > 30MPa as the compressive strength of agglomerate is observed, especially in the case where large size/higher furnace chamber. Therefore, enough compressive strengths will be considered as one of most important standard when estimating the feasibility of raw material coking.Because of compression Intensity may be by being compacted and/or compress influenced, so this process has a very big significance.

Especially when can not precisely enough observe the specific water content of raw material or agglomerate, it may appear that further Difficulty the result is that agglomerate is subjected to high stress during heat supply, and is especially subjected to explosion or the decomposition of other forms.It is above-mentioned Observation shows that effective operation of furnace needs to provide raw material or agglomerate in the narrow margin of tolerance as much as possible, especially exists In terms of compressive strength and water content.

From these considerations it is readily apparent that when finding new method and apparatus, pays special attention to following point: being defined on The specific heating curves of raw material in furnace chamber；During being defined on coking, by Raw material processing at agglomerate and equiulbrium flow and material The specific method parameter of raw material during type and volume (in particular for the gas issued in coking), it is especially warm Degree, duration, pressure；Using and disposition option.

So far, coking carries out in the gas burner with perpendicular chamber or the coking furnace with horizontal cavity.The latter can be with It is divided into two types: (integrated form) horizontal cavate furnace with narrow furnace chamber and the charging for standing upright on indirect heating therein, And with dome-shaped furnace chamber and so-called hot (non-) recovery furnace of charging therein is lain in, hot (non-) recovery furnace at least may be used With from top indirect heating.Current hypothesis is the future that the coking furnace of both types may be utilized no longer for raw material Task optimizes on schedule.Seem develop a kind of new concept for coking furnace of new generation, especially in face of being expected that by it The case where different material to utilize wide scope.Therefore, it set forth below is a kind of new furnace concept, particularly can also be applied In the purposes of former common (coal) raw material.

Summary of the invention

Purpose about present invention hereinafter defined, it is advantageous that a kind of device and method are provided, it even can be special Be in perpendicular cavate furnace the unconventional raw material of coking, more specifically lignite and/or weak caking coal and/or biomass and/or Petroleum coal.Here it can be beneficial that preparing, providing and/or managing unconventional raw material in such a manner, so that after coking The product of acquisition can as far as possible with conventional raw material so far (such as conventional bituminous coal agglomerate) the case where it is the same or similar Mode uses.

Particularly it is arranged herein for by producing coke especially from at least one solid material of the following group , furnace apparatus at least one vertical furnace chamber, especially coking furnace: lignite, weak caking coal, biomass, petroleum coke Charcoal, petroleum coal；The furnace apparatus includes at least one agglomerate drier that setting is used for thermal conditioning agglomerate made of raw material, and At least one furnace chamber of heated wall is especially coupled and had with agglomerate drier below agglomerate drier；Wherein, agglomerate is dry Dry device includes heating facility and can use its agglomerate reservoir heated, and wherein, agglomerate drier is set as Continuous on agglomerate conveying direction or increased temperature stage by stage is established in agglomerate reservoir, especially in 60 to 200 DEG C of ranges At least two or three interior temperature levels.

It has been found that combine raw material as described herein, in very accurate way by temperature adjust to it is different increasingly High temperature levels are useful.It, in this way, particularly can be in mild mode by the water of agglomerate in addition to other factors Content is reduced to desired value.It has been shown that these preparation measures are vital for subsequent coking operation.The group of passing through The controlled processing of block especially combines the controlled temperature state in furnace chamber, can be with the raw material of the special wide scope of upgrading.Therefore, this At least part of a little raw materials by from cement industry log or material composition not can not.

Temperature levels can steadily increase, and/or can limit specified temperature levels, especially along gravity direction At the different height plane for conveying the reservoir of agglomerate.Desired temperature water can be individually adjusted for each operation or raw material It is flat.

The continuous operation for being used for coking can be established in corresponding vertical furnace chamber.In this case, agglomerate bed with Temperature increase migrates across at least one humidity province.In such circumstances it is desirable to throughput can pass through especially output system System is to establish and adjust.With with batch operation as defined in fixed temperature, on the contrary, in this case, such as coal turns to coke Change/upgrading can be carried out continuously.There may be temperature regimes, and may influence operation and/or may be in each humidity province Middle exhaust byproduct.

Temperature of the continuous operation for example on the material of furnace apparatus (more specifically silica) in perpendicular cavate furnace It is also had the advantage that in terms of stress.The material largely may remain in the temperature of 600 DEG C or even 800 DEG C or more, and And without being cooled to lower temperature repeatedly.As a result, there is less stress/crack in the material.

Furnace apparatus may include for providing the supply unit of agglomerate on agglomerate drier.For supply unit is also set up The agglomerate produced by press is such as delivered to agglomerate drier.Supply unit set at least to ensure to drier continuously or point Criticize ground supply agglomerate.

What it is positioned at drier upstream is coal bunker, and agglomerate can be supplied to coal bunker continuously or in batches, and agglomerate can be with Especially by agglomerate is slid into agglomerate drier, and continuously or in batches transported out from coal bunker.

Input system can be set in the top of (corresponding) furnace chamber.This allows to be supplied based on gravity.

The preferred whole design of furnace apparatus is the perpendicular cavate furnace with vertical furnace chamber.Vertical furnace chamber is such furnace chamber, that is, group Block is particularly based on gravity and is conveyed in the vertical direction through the furnace chamber.

Raw material can particularly include the entire scope of soft, lacklustre and glossiness brown coal and flame coal.It is special It is not to have been realized in good effect using from the Rhine, labor Ji thatch and Indonesian brown coal.Also send out Existing, device and method described herein are also applied for the utilization of Russian brown coal and flame coal and petroleum coal.Based on basis The classification of DIN, ASTM and UN-ECE, raw material particularly may also include following coal type and peat, schematically reproduce herein. In the context of the present invention, with reference to German DIN, it has been shown that, the coal especially suitable for utilizing includes according in the DIN The soft brown coal of middle classification, matt brown coal, glossy brown coal and flame coal.

Numerical value in upper table is mass percent；About the numerical value of volatile component, under the conditions of " anhydrous ash (waf) " into Row measurement, in other words, measures in the state of anhydrous and ashless simultaneously.

About the purpose of the present invention defined below, it is advantageous on furnace apparatus as described herein, furnace chamber at least Side, at least one of the heated wall of lower half, particularly lower one third, there are at least one level heating channels, and And also start above it, particularly at least in the upper half or in intermediate one third, exist with serpentine fashion in multiple height The heating channel extended in plane, these heating channels respectively can individually be heated by least one burner.It is such Heating can provide a variety of advantages described herein, and can also particularly match with any specific operation of agglomerate drier It sets or mode is unrelated.In terms of being handled before being supplied to furnace chamber agglomerate, agglomerate drier provides excellent Point.Then, heating channel later phases in operation work to the agglomerate being present in furnace chamber.Be that as it may, but this two Kind measure is directed to the temperature regime extremely accurately adjusted or the supplying energy into agglomerate.The processing of furnace chamber upstream is more smart Really, the energy supply in furnace chamber can more accurately or efficiently lead to desired effect.

According to an exemplary embodiment, it can especially rolled into a ball according to measured value for drying the agglomerate reservoir of agglomerate The different height and position of at least two of block reservoir is heated at least two different temperature levels in a manner of being adjusted, should Measured value can measure and come the group of self-contained at least following item: temperature, water content in agglomerate reservoir；Especially 60 First temperature levels of (especially up to 95 DEG C) between to 105 DEG C, the second temperature between 105 to 200 DEG C is horizontal, and It is optionally included at least one other temperature levels of the temperature levels between 95 to 105 DEG C.Horizontal upper of end temperature Limit can be established especially in such a manner, so that devolatilization is still not present.The upper limit of relevant temperature level can be derived from advance For the temperature value that specified raw material determines, and for example it is recorded in data storage, or can optionally during operation Especially by agglomerate drier/at least one pressure sensor and/or gas sensor and/or humidity sensor come It is specified.This allows agglomerate more strongly continuous drying in mild mode, without excessive temperature stress or material stress.

According to an exemplary embodiment, it is stored up according to measured value, drying for adjusted to agglomerate agglomerate Storage can be heated to being no more than the minimum moisture of 1 to 5 quality %, especially 2 to 4 quality % in the exit of agglomerate drier The point of value.This allows that the initial moisture content within the scope of from 10 to 15 quality % of agglomerate is become less than 5 matter in mild mode The moisture value of % is measured, this is advantageous subsequent coking.In this case, in agglomerate drier, especially in phase May exist humidity sensor and/or temperature sensor at the height and position answered.Under conditions of with enough measurement accuracy, only Temperature adjusting is carried out according to water content to be sufficient.Such as capacitor or spectral measurement method can be used to measure water content.So And, it is preferable that there are the measurement facilities in particular for measurement pressure, volume and/or temperature of redundancy.The adjusting is preferably especially It carries out via temperature measurement, or is optionally only carried out via temperature measurement.

1350kg/m based on corresponding agglomerate³Density, the block bulk density in furnace chamber can be 650 to 850kg/m³'s In range.

Herein, a kind of method is additionally provided, this method is used for by especially from at least one solid of the following group Raw material produces coke: lignite, weak caking coal, biomass, petroleum coke, petroleum coal；The raw material is mentioned in the form of agglomerate For and be supplied to the vertical furnace chamber of especially coking furnace, and be particularly supplied to above-mentioned furnace apparatus；Wherein, agglomerate supplies first Agglomerate drier should be arrived, it is consistently continuous drying in the advanced speed wherein with agglomerate according to predetermined temperature profile, and especially Ground is dried at least two or three temperature levels within the scope of 60 to 200 DEG C, and is subsequently supplied into furnace chamber.This allows agglomerate By can by accurately authorizing very much in a manner of carry out predrying and pretreatment, and at the same time by mild management.Here, furnace Agglomerate in chamber can carry out thermal conditioning according to the advanced speed of agglomerate in continuously bigger degree.Gradually with path More strongly increased energy supply can be realized effective method.Energy supply can increase particular according to residual moisture content, Such as by being filled with hot gas to each heat levels, relative to the out-of-proportion heat of temperature gradient between previous heat levels Gas.

The coking of lignite, weak caking coal or biomass is the operation that should be controlled in very accurate way, so as to Especially allow to avoid the softening (and decomposition) of agglomerate.It should avoid within the temperature range of so-called " plastic zone " that raw material softens (for certain lignite, particularly from about 350 to 410 DEG C) coking.This can be by establishing temperature regime and/or heating curves come complete At.

For many raw materials, main devolatilization carries out in " plastic zone ".Therefore, in " plastic zone ", the knot of agglomerate Risk of the structure composition closest to change.By method described herein and equipment, " plastic zone " can specifically distribute to furnace chamber In height and position, especially it is snakelike heating channel height at.This allows to monitor and/or adjusting operation is especially good to obtain Effect and make raw material especially leniently coking.

It has now been found that especially combined with the predetermined temperature state in furnace chamber, and/or with via can individually cause The predetermined indirect heating in dynamic heating channel combines, can also be specific in a manner of targeted in the region of " plastic areas " The discharge of ground progress gas.For example, at least one height and position of gas discharge pipe line, more particularly the second height and position (under Face will be described in further detail) it is specifically arranged in the region of " plastic zone ", especially in the center in the region or the region Upper end.Then at least one gas discharge pipe line is connected to furnace chamber in the height and position for corresponding to " plastic areas ".This makes can To effectively cancel out any Convective Heating due to caused by the unstrpped gas of rising.

Experience have shown that raw material then undergoes some solidifications again at about 470 to 500 DEG C or more.Particularly, lignite agglomerate During through " plastic zone " seem that coking cannot be resistant to well with the agglomerate made of weak caking coal.In this point On, it appeared that there are the risk that the agglomerate made of these raw materials collapses or is crushed.Therefore, special be suitble to should accurately be established In the temperature profile of specified raw material.In this aspect, being pre-dried in agglomerate drier can be considered as preliminary step.In short-term In, even if disproportionately high water discharge also results in agglomerate explosion within the temperature range of reaching 350 DEG C, this be by Caused by moisture and gas fraction escape.

It therefore, not only can be by extracting the gas of release out in different height position but also control/adjusting can be passed through Temperature profile is established by the energy of external burner supply.Particularly, it can also be taken in snakelike heating channel such as clear The measure of vertical access is removed or blocks, for example also to allow to establish energy input in " plastic zone ".

According to the present invention, at least one of above-mentioned purpose also by least one vertical furnace chamber using gas discharge Device realizes, with for discharging at least three kinds of gas types from furnace chamber, to establish vertical temperature in the agglomerate bed in furnace chamber Spend profile.

According to the present invention, at least one of above-mentioned purpose also by using by above-mentioned gas tapping equipment from vertical furnace At least at least one of three kinds of gas types gas type of chamber discharge realizes, with for indirect heating furnace chamber at least One burner provides the purpose of fuel gas.

According to the present invention, at least one of above-mentioned purpose is also by a kind of for producing the furnace apparatus of coke briquette come real It is existing comprising above-mentioned gas tapping equipment and furnace apparatus, in at least side of furnace chamber, in lower half, more particularly lower three/ In one at least one heated wall, furnace apparatus includes at least one level heating channel, and on it, more particularly also at least Start in the upper half or at the one third of middle part, furnace apparatus include extended in multiple elevation planes in the form of snakelike plus The passage of heat, these heating channels respectively can individually through at least one burner, especially by the gas discharged from furnace chamber Body is heated.

According to the present invention, at least one of above-mentioned purpose also passes through a kind of method for producing agglomerate by carbonaceous solids raw material It realizes, this method is not only included in agglomerate drier the dry agglomerate made of raw material, but also is included in furnace chamber burnt Change agglomerate to form coke briquette, wherein at least three height and positions by gas in furnace chamber discharge, at least three height and positions It is distributed in at least half height of furnace chamber, gas is at least partially through furnace chamber with heating furnace chamber.This method can be by upper Furnace apparatus is stated to carry out.

It can be referred to below about the operation mode of corresponding furnace chamber.Ingredient mass is small 4 to 15 hours, especially 6 to 9 When time in pass through corresponding furnace chamber.In this procedure, ingredient mass be especially from 100 to 200 DEG C in the form of the multistage it Between initial temperature (especially 150 DEG C) be heated to the final temperature between 900 to 1100 DEG C.Required heat can be at two It is generated in channel, the two channels are arranged in the side of corresponding chamber and can be heated by multiple external burner, and should Heat is by stone partition wall indirect transfer into corresponding furnace chamber.

2 to 10, especially 4 to 6 well chambers are usually joined together to form furnace chamber.The height of each well be 3.5 to 10mm, especially 5 to 8m, the width of each well are 150 to 600mm, especially 200 to 400mm.

The type for forming the coal of agglomerate especially includes having 45 matter of volatile coal ingredient (vc) and > of the mass of >=45 % Measure (hard and soft) lignite of the water content of %.The raw material for being processed into agglomerate optionally includes with >=28 mass % to 45 The weak caking coal (especially gas, gas flame and flame coal) of the volatile component of quality %, or there is the matter of <=22 Measure the weak caking coal (especially forging coal and meager coal) of the volatile component of %.The adhesive property of weak caking coal itself compared with It is low.In hybrid manipulation in front, weak caking coal can be mixed with bonding agent, to increase coal during briquetting operations The bond effect of the bond quality of grain.

Due to its crucible coke property, rich coal particularly represents the coal (conventional " coking coal ") of bonds well.In addition, so-called Forging coal and bottle coal also belong to the good coal of bonding.The coal of every other type is referred to as weak caking coal in the present specification.

It has been found that agglomerate can also be by bituminous coal (such as anthracite (vc < 12%), meager coal (12% < vc < 19%), the mixture of bottle coal (28% < vc < 35%), gas flame coal (35% < vc < 45%) or these coal classes) composition, It is optionally also using high-grade fertile (coke) coal (19% < vc < 28%).By these percentages, and the product based on coal The standard of kind, or even more specifically distribution is possible.

Particularly, raw material can be ground into pelletizing in porous plate roller mill, especially with 0 to 2mm granularity ball Group.It has been found that being particularly conducive to bonding (they are easy bonding) by pelletizing/particle that perforated plate roller mill generates, therefore Simplify the briquetting operations (compacting) in downstream.

After mixing, raw material is compacted.The compacting process (coalescence) preferably carries out in formed channel press machine.It has sent out It is existing, by channel die geometry, can be given birth in a manner of narrowing with cross section and exporting the Venturi tube that cross section broadens Produce especially measuring body agglomerate.Other kinds of press cannot provide fairly good quality results.

Furthermore, it has been found that if raw material is pressed through the cross section to narrow after shaping in a mold, it can be real Existing extra high agglomerate intensity.When separated thereafter along the outflow portion to broaden lead raw material when, even higher agglomerate may be implemented Intensity.Advantageously, the part for narrowing is shorter or shorter than the part that cross section broadens than outflow part.

It has been found that the agglomerate of flattened cylindrical shape (plate-like, ice hockey shape) generates special either before or after coking Not good intensity value.Particularly, the ratio between agglomerate diameter and agglomerate height are 1 to 5, especially 2 to 3 in heating and coking operation side Face also provides good result.Agglomerate preferably has 20 to 100mm diameter.Agglomerate is especially by 0 to the coal between 2mm Particle size generates.

If showing that required intensity can also be realized by different molds or different types of press, agglomerate Can also optionally have different geometries, such as such as cube, bulk, sheet, conchoidal, cushion, spherical shape or egg Shape geometry.However, having been obtained for ice hockey shape is best practices in experiment so far.

The parameter of this method is as follows: compression pressure, compression time, compression temperature.Especially 120 to 150MPa, especially It is to be compacted at 140MPa.Especially it is compacted at a temperature of between 60 DEG C to 100 DEG C.Compacting is especially grown Up to 15 seconds time.

It has been found that the type of coal described herein can mix in operating upstream step with coke promoters, to make Coking is more effective and coke product is made to have higher quality, such as higher intensity or higher reactivity.

According to one embodiment, at least one coke promoters are supplied in briquetting operations (during compacting), to be used for Especially improve the efficiency of downstream coking.Coke promoters can select either individually or in combination, especially from so far It is selected in verified one group of coke promoters useful for conventional raw material.

It has been found that by aforementioned present invention, when using lignite as raw material, the carbon content C of coke produced (fix) value to 55% or more can be improved, even if so that in the direct smelting reduction process of production steel after the coke It is also able to use in (the COREX/FINEX technique of PRIMETALS).

Compress and coking operation before, in single phase or multistage hybrid manipulation, raw material preferably with bonding (bonding) It is mixed with coking system, especially to improve the quality of the coke produced or to promote the agglomerate pressure from weak caking coal type Contracting operation.This auxiliary agent mixes within the temperature range of 30 to 120 DEG C preferably before briquetting.

Auxiliary agent can be particularly optionally in combination selected from the following group: molasses, sulfite waste liquor, sulfate waste liquid, third Alkane pitch, cellulose fibre, HSC (High-Conversion Soaker Cracking, the tower cracking of high conversion) are remaining Object, (Residue Oil Supercritical Extraction, residual oil are overcritical by the mixing HSC/ROSE from petroleum industry Extraction) residue.

In general, it is distinct between coke promoters and bonding (bonding) auxiliary agent, it can be to Mr. Yu although being also likely to be present The auxiliary agent of both functions is able to achieve for a little raw materials.

It has been found that addition water is often unfavorable in the case where coal class described here.For example, lignite is usual Water content with > 45%.In order to ensure the high efficiency of compression forming operation, it has been found that, observe certain (less high) Water content it is meaningful.In particular, it was found that about 20% water content is advantageous.Accordingly it is also possible to carry out preliminary It is dry.

Subsequent briquetting operations especially carry out within the temperature range of 40 to 90 DEG C, especially in 55 to 65 DEG C of temperature model In enclosing.This coalescence mode leads to coal agglomerate produced part compressive strength with higher and tear strength, especially > The intensity of=30MPa.

Agglomerate can be placed on above main dryer with crane, and can be slid through main dryer, be passed through coking Well, and travel further into the dry cooling equipment of coke.

It has been found that leniently being dried in main drying process after coalescing to the water content between 2 to 4 quality % Agglomerate is advantageous.

The primary operational of dry agglomerate is carried out particularly by top dryer unit, and for by the water content of agglomerate from About 20 mass % are further reduced to about 3 mass %.In this way it is possible to which the heat for ensuring to be transmitted in chamber will not be dissipated to height The water evaporation of ratio, it has been experienced that this may also cause agglomerates.

Main drying process is especially carried out in two stages but it is also possible to be single phase or multistage operation.What is used is dry Dry medium is preferably hot waste gas/unstrpped gas, is produced by the burn operation in the heating channel for the furnace chamber being located at below drier It gives birth to and can be passed through upwards in the channel realized with top form.

For intersecting stream mode, the arrangement in these channels is especially with the shape intersected.It at least partly, can also be right Countercurrent or cocurrent arrangement is provided.

In order to improve drying efficiency, the setting main dryer unit dry for trunk can be couple to flame monitor External burner, can be for all or two or more drying stages or an only drying by the external burner Stage provides additional exhaust gas.Main dryer unit and corresponding furnace chamber can by that can seal, it is especially hermetically sealed Locking system is separated from each other.Locking system can particularly be couple at least two furnace chambers in the form of dual-active plate.

Raw material/raw material (or agglomerate) preferably pass through application in the coking vertical shaft (or furnace chamber) being located at below main dryer It is heated specific to the state of temperature of raw material.For example, following temperature state generates advantage: in the first phase, especially in 0h Agglomerate is heated to 300 to 400 DEG C of temperature range in about 4 to 7h period, is operated with 0.75 to 0.9K/min temperature Degree increases to carry out.In at least one other step, wherein so that agglomerate is reached 300 to 1100 DEG C of temperature range, with 2.6 to the 3K/min rate of heat addition is heated.

For certain raw materials, heating is only carried out with the constant rate of heat addition in a single stage and is also advantageous, and this It equally can be associated with desired high coke strenth.

By sustainable method/method (especially in conjunction with specific coalescence technology) described here, phase can be provided There is the coke or coal of relative high quality for raw material.Even if the agglomerate shape needed for keeping is also ensured in coking Shape, especially cylindrical ice hockey shape.In coking, the quality and volume of coal shrink 40% to 60%, especially 50%, therefore also need the desired high compressive strength and tear strength of > 30MPa (coke strenth (CSR) after especially reacting) And the hypoergia of CRI (coke reactivity index) value < 55%.The reactive upper limit is necessary, because of otherwise coal group Block may spontaneous combustion in the presence of air.So far, quality level defined in these limiting values can't reach described Rudimentary coal quality.Particularly, method and apparatus so far already leads to the cracking in agglomerate, or the group of even resulting in Block-shaped complete destruction.Particularly, the variation of quality and volume can occur in the same scale.

By method described here, agglomerate shape (ice hockey shape) can be kept, the result is that the pressure loss, heat transfer, stream Driving wheel exterior feature and other methods parameter remain able to predefine.

Corresponding furnace chamber is especially made of fire resisting earth silicon material.

Aspect related with the optimization of heat/energy balance is described below.

In the transverse direction of corresponding furnace chamber, there may be the heating pipes being integrated into wall, especially on two sides.Heating Pipeline can be by least one, preferably four external burner be lighted.Particularly, burner one couples on top of the other Channel is heated to level.Here, exhaust gas from heated wall or fuel gas also be can use for energy, for this purpose, can Selection of land passes through flue gas air blower auxiliary discharge amine.

According to an advantageous exemplary embodiment, three burners are arranged/are couple to three lower parts or lowest part is horizontal Channel.Three following channels extend horizontally to the opposite side of furnace chamber, they become to boot up accordingly perpendicular there Straight heated well.It has been found that heat-flash source can be formed there in three burners of well/furnace lower area centralized arrangement, this Mean 500 DEG C of > of temperature needed for forming coke formation in chamber.

According to an advantageous exemplary embodiment, above lower part or lowest part horizontal channel, in heated wall, formed The channel booted up with serpentine fashion (starts counting) especially as fourth lane from bottom.Burner can equally connect It is connected to serpentine channel.It has been found that passing through the serpentine channel, it can be ensured that advantageous heat especially in the vertical direction point Cloth.In upward way, the exhaust gas that is generated by corresponding (especially the 4th) burner can with Slow cooling so that Ensure gradually to transfer heat on vertical direction in charging/bed of agglomerate.This gradual heat transfer generates various advantages, either in energy Amount aspect, or at aspect related with the dimensional stability of agglomerate, or aspect usually related with mild coking. Burner can particularly with from coking well natural gas and/or coking furnace gas light.

Due to above-mentioned configuration, it is possible to abandon providing being used to generate burning gases by coal so far in each furnace chamber upstream Expensive generator gas cell, this will also have the disadvantage distributing aspect.

Continuing for the use of for the byproduct for being related to being formed in coking is described below.It has been found that spy It is not to combine raw material as described herein, takes out byproduct from the different height position of each furnace chamber and be advantageous, so as to reality Show highly selective and can also effectively influence state of temperature.

According to an advantageous exemplary embodiment, the high heat gas formed in each furnace chamber in coking exists It is extracted at 1 to 5 extract part of different height position, to discharge and transmit from furnace chamber further to be utilized.In phase At the extract part answered, the port with predetermined angular can be particularly existed.

So far, usually there is the undesirable phenomenon for being referred to as purge gas coking on the top of furnace chamber.By the bottom of at Purge gas caused by the gas that portion releases causes and sets in intracavitary rising, and within the scope of undesirable or uncontrollable temperature Set the undesirable reaction of agglomerate above.Rule of thumb, in these upper areas of chamber, this is along with undesirable right Spread the reduction of heat and coke quality.So far, it means that in many arrangements or furnace configuration, it is not easy to control in bed Temperature profile.Therefore coking is occurred in a manner of more or less confusion.

It has been found that purge gas can be prevented by the arrangement with the extract part that different height position is arranged in Coking, so far, purge gas coking usually occur on the top of furnace chamber.

In addition, the advantages of measure, is, it can be from step emission in coking in each stage of coking operation The gas of releasing, and they are therefore supplied to specific gas treatment facility and/or converts them into valuable chemistry Product.Herein, grading extraction refers to the extraction in different height position and gas with various type or gas composition.It has sent out It is existing, it, can also be for extraction by making a reservation for the distance (according to raw material or the type of coking) between extract part The composition of gas carries out the optional pre-selection of height.

Advantageously, one, two or more or all extract parts are located at well/base portion of respective chamber along the vertical direction At outlet top at least 50%.This is in particular, in that with advantage in terms of arranging area co-pending before output system.Therefore, unstrpped gas It can be sucked out from upper area, and be returned in well by lower part " absorption " system.For this purpose, corresponding lower gas discharge pipe It can also be re-used as gas feedthroughs.Therefore, gas can be partially through hot agglomerate, so as to establish increased quality Effect.

In downstream process step, the gas generation high value substance that can be discharged by these, such as methanol, synthesis of natural Gas or dimethyl ether.It has been found that being arranged from coking operation if gas fraction required thus is formed by position at it Out, then these gases can remarkably more efficiently be produced.

Equipment so far has the drawback that, at most can only carry out single phase discharge to the gas formed in chamber.In In this case, especially in the upper area of respective chamber, unfavorable heat transfer and chemical conversion event occurs, not only damage is burnt Change efficiency, and damages the quality of gas preparation.

Continuing for the use of for the energy for being related to consuming or release during coking is described below.Particularly, come Self-heating system or flue gas from cracking units can be used for the circuit of drier.In this case, in order to humidify The dry gas of circulation, there may be the extracting sections adjusted.Also can produce steam, in particular for heating equipment, The steam station of pipeline, valve.Steam can also be obtained and/or for handling raw-gas in the form of process steam.Sufficiently high Under temperature levels (especially in the gas of the exhaust gas from minimum burner), the confession to waste heat recovery unit can be carried out It answers, and/or hot flue gas can be supplied to dry cooling facility.

According to an advantageous exemplary embodiment, airtight output system setting is below (corresponding) furnace chamber, and energy It is enough that hot coke is transmitted in dry cooling facility.Output system can be structured as the mode of well.Output system can be set to Adapt to the amount of the coke from two adjacent chambers.

According to an advantageous embodiment, it introduces especially by introducing cold inert gas, in particular from below without adding Add water, the temperature levels by coke from 900 DEG C of > are cooled to 200 DEG C of temperature levels below.It has been found that flowing through cooling upwards Well coke beds and the cooling gas for obtaining heat in this way can be supplied to heat exchanger, in particular for generation steam Heat exchanger, while being accompanied by the improvement of especially energy balance.In order to provide pressure difference, especially air blower can be provided Form depressurized system, and the depressurized system can be couple to dry cooling facility and/or heat exchanger.

By this arrangement, the coke temperature below the dry cooling facility lower than 200 DEG C may be implemented.For example, can be with Realize the rocking bar or pendulum construction for coke to be discharged.Therefore, cold cooling gas can be introduced into dry by free bed region In dry cooling facility.

By the way that especially each equipped with the point of observation 12.22 of sensing system 14.4, the heat that can monitor furnace chamber is adjusted It saves and carries out its optimization/adjusting in a relatively accurate manner.

Fig. 4 B shows the plan view of x/y plane.In fig. 4 c it is illustrated that xz side view.In figure 4 c, in three differences Height and position shows gas vent 12.6,12.7,12.8, as being described in more detail in Fig. 6.

For optimal heated condition, particularly, at least four external burner 13 are arranged in each heated wall, outside these Before and after burner is upwardly-directed in the side of x-axis or y-axis and alternating is oppositely arranged at chamber 11.

Extend in each comfortable (only) height and position/elevation plane in three lower parts heating channel 12.1, and each freedom Individual burner heats respectively.Exhaust gas is passed directly into the exhaust gas flue extended along the vertical direction from three lower parts heating channel In 12.3.The 4th heating channel 12.2 started counting from bottom extends on multiple horizontal planes and by single or multiple burnings Device 13 is lighted, and the exhaust gas from burner flows through the remainder being located above first part in the 4th heating channel with serpentine fashion Point.

Particularly, horizontal heating channel 12.1 orients in parallel with each other, and perpendicular to corresponding vertical exhaust gas flue 12.3。

The lower part of furnace is preferably no longer heated, and (about for the complete coking of coke and the preliminary cooling of coke 1m).The part can be described as pending area, can support thoroughly coking completely and complete degassing, Coke Quality With active influence.

About return system 18, can also be presented below: agglomerate drier is located above furnace chamber, and can be via (vertical) Exhaust gas flue is fed with the exhaust gas from related burner.The exhaust gas can individually be dried back in two in agglomerate drier It is used as dried medium in road, hereon referred to as preliminary drying stage and primary drying phase.In other words, it can be set two to dry back Road is especially respectively supplied by the thermal energy of the burner from furnace apparatus.Two circuits can also be optionally equipped with additional External burner, with the purpose especially for redundancy or more flexible adjustment possibility.

The hot waste gas for being thermally generated system (the first dry circuit) from primary can be provided by least three external burner, The external burner is connected especially to three horizontal heating channels at the bottom being arranged on corresponding furnace chamber.From secondary heat The hot waste gas of generation system (the second dry circuit) can be provided by least one external burner, which is connected to Snakelike heating channel above horizontal heating channel.

Fig. 5 shows all parts for the dry cooling facility 19 being arranged in below furnace chamber 11.Pass through pump 19.1 and heat exchange Device 19.3 comes operating gas circuit 19.5, and in gas return path 19.5, coking block mass 6 countercurrently cools down in cavity 19.7, gas Enter the cavity by least one entrance 19.9 and is discharged again by least one outlet 19.8.It sets in furnace chamber 11 outlet Underface, and separated by baffle or wall outstanding with furnace chamber 11.The advantages of this arrangement, is that the agglomerate from furnace chamber 11 is first First surrounded by the cooling gas stream by very highland heating.Therefore, mild cooling can be carried out in this way.Again It is secondary, minimize (temperature) stress on agglomerate.However, cooling can be absolutely effectively.At least one flowing inhibits top Or gas turns unit 19.6 is centrally arranged in cavity 19.7.This allows to adjust flow profile.Particularly, it can prevent The prevailing transmission of energy and/or quality that the center of cavity 19.7 develops into.

The specific features of perpendicular cavate furnace are that the dry cooling of coke is arranged in below furnace chamber in a manner of " precise match ".Cause This, the cavity of dry cooling facility can have cross-sectional profiles identical with furnace chamber.This direct gravity for being conducive to agglomerate drives Dynamic conveying, and continuous operation can be simplified.Particularly, transition is seamless, this is because in furnace chamber and dry cooling facility Between there is no physical separation.

At least one top being especially centrally located in radial directions and/or gas turns unit 19.6 can ensure cold But gas is uniformly distributed in radial directions and is especially also directed into outlet 19.8 in an uniform manner.

Fig. 6 shows the furnace apparatus 50 including gas discharging apparatus 30, and gas discharging apparatus 30, which has, is used for the first height position The one or more gas discharge pipe lines 31 set, gas discharge pipe line 31 can be couple to phase via couplings or interconnecting piece 31.1 The furnace chamber 11 answered.Additionally provide the one of the height and position other at least one (currently used for second and third height position) A or multiple gas discharge pipe lines 33, each gas discharge pipe line equally include couplings 33.1.In addition, multiple mixers are arranged 35.1 pump 35.2 at least one with the gas for further managing discharge.On corresponding furnace chamber 11, setting is respectively corresponded In the gas vent or interconnecting piece 12.6,12.7,12.8 of corresponding height and position.

Here, unstrpped gas can be aspirated at not less than three elevation planes, separately for each furnace chamber: warp By the upspout (highest type position) in furnace roof, by the way that one or more connections at the desired height position of furnace chamber are arranged in Portion, and by one or more vertical exhaust gas flues, especially in corresponding heated wall (medium height position), and this Outside, by the one or more interconnecting pieces being arranged at the desired height position of furnace chamber, and by one or more vertical useless Gas flue, especially in heated wall (smallest height).

The unstrpped gas of discharge via separation/cooling by isolated unstrpped gas gathering line and can collect, and so It is combined in one or more unstrpped gas gathering lines afterwards.It has been found that (especially in the case where directly drawing unstrpped gas Be the downstream of the lock-out facility of agglomerate input system nearby), unstrpped gas can be reduced from furnace chamber and be transmitted to preliminarily dried Risk in device, this is mainly due to the decompressions developed into herein.This can be further improved quality.
