Technical Field

The invention relates to the technical field of treatment of household garbage and combustible waste, in particular to a household garbage magnetizing, pyrolyzing and gasifying treatment device.

Background

The pyrolysis treatment method of the household garbage is divided into an incineration treatment method and a pyrolysis gasification treatment method. The volume of the garbage can be reduced by 98 percent and the weight of the garbage can be reduced by about 95 percent.

The domestic refuse incineration treatment method is characterized by that it uses incinerator to make high-temperature pyrolysis combustion treatment of refuse, and its treatment method is simple and treatment speed is quick. But because the heat value of the household garbage is lower and the water content is higher, auxiliary fuel needs to be provided for supporting combustion. The investment and the operating cost of incineration treatment equipment are both higher, and the direct incineration treatment of garbage has the hidden trouble of environmental pollution and the smoke is not easy to reach the standard for treatment and emission. Particularly, in the incineration process, the incineration temperature is converted from low temperature to high temperature, the waste gas treatment process is converted from high temperature to low temperature, and the generated dioxin is processed improperly in the generation range of the dioxin, so that the harm to the human health and the environment is large.

The garbage pyrolysis gasification is that organic matters in garbage are dried, oxidized, reduced and pyrolyzed by smoldering in a generator (furnace) under the condition of oxygen deficiency, chemical bonds of the organic matters are broken by utilizing the heat energy of dry distillation, the organic matters with large molecular weight are converted into CO, H2, CH4, tar, volatile gas and the like with small molecular weight to prepare combustible gas, and then the prepared combustible gas is combusted by a combustor or is used as fuel gas after being purified to be directly used for boiler fuel recycling. Combustible substances such as straws and the like are required to be added for pyrolysis and gasification of the garbage to improve the heat value and reduce the water content, so that the pyrolysis condition is met. The pyrolysis and gasification treatment speed of the garbage is relatively slow, and the treatment capacity is small.

The fixed bed pyrolysis gasification generator (furnace) is mainly divided into a downdraft type and an updraft type;

the downdraft pyrolysis gasifier is charged from the upper part of the gasifier and operates under the condition of micro negative pressure, an air inlet of a gasifying agent (air) is arranged at a certain height on a grate, a high-temperature area, namely an oxidation area, is formed corresponding to the air inlet, materials on the upper part of the oxidation area are subjected to the high temperature action of the oxidation area to form a pyrolysis area, the lower part of the oxidation area is a reduction area, combustible gas is discharged from the lower part of the grate, ash falls into an ash chamber below the grate, and the downdraft pyrolysis gasifier is suitable for large lump materials and low-moisture materials and has the defects of high ash content in the gas and high gas temperature.

The updraft pyrolysis gasifier furnace is fed from the upper part of the gasifier and runs under the condition of micro-positive pressure, a gasifying agent (air) upwards enters the gasifier from the bottom of the furnace through a grate, an oxidation zone, a reduction zone, a pyrolysis zone and a drying zone are formed on the upper part of the grate, the temperature is also gradually reduced from bottom to top, namely the gasification temperature is reduced along with the increase of the height (the thickness of a material layer) of a reaction layer, gasified combustible gas is discharged from the top of the furnace, the flowing direction of the airflow of the gasified combustible gas is opposite to the moving direction of materials moving downwards, the materials flowing downwards are dried by hot gas flowing upwards to remove moisture, the requirement on the size of the materials is not high, the pyrolysis gasification is facilitated, the gases have a filtering effect, the ash content of the produced gases is reduced, but the produced tar content is relatively high. In order to obtain good quality of combustible gas and gas quantity, the reaction temperature needs to be controlled. Air ratio has a greater influence on gas production and combustible gas quality. The crude fuel gas produced by the up-draft pyrolysis gasifier can be directly used for the combustion of supplementary fuel of a boiler or a heating furnace.

The pyrolysis gasification furnace is used for gasifying biomass and has a good combustible gas preparation effect. Because the biomass raw material is single, the heat value is higher, the water content is lower, and the operation control is easier. However, for domestic garbage, due to the complex material types, large water content and low heat value of organic raw materials in the domestic garbage, the preparation of combustible gas is not easy to realize the pyrolysis gasification of the domestic garbage, and the combustible gas is greatly influenced by the structure of a furnace body, the type of a gasifying agent and the parameters of a pyrolysis process.

Rural domestic garbage is a problem to be solved urgently because of small yield, high conveying cost and no reliable treatment method. The pyrolysis gasification technology is particularly suitable for treating dispersed and small amount of rural domestic garbage due to good reduction effect, no secondary discharge, lower investment and operation cost and convenient operation and maintenance.

The lower part of the upper arch furnace body is a furnace body, the upper part of the furnace body is provided with a mark plate seat, and a delivery mark plate is arranged on the mark plate seat; two cleaning doors are arranged in the middle of the furnace body and are arranged opposite to each other by 180 degrees; two ash removing doors are arranged at the lower part of the furnace body and are arranged opposite to each other for 180 degrees; an ignition door is arranged in the middle of the furnace body cleaning door in the direction of 90 degrees horizontally; a grate hand-cranking device is arranged at the lower part of the furnace body ignition door; the lower part of the furnace body grate hand cranking device, namely the bottom of the furnace body, is provided with a sewage discharge pipe opening. An ash removal door is arranged opposite to the sewage discharge pipe opening, and a sealing door is arranged on the ash removal door. The furnace body is internally composed of an outer wall plate, a fire-resistant arch, a fire grate, an ignition chamber, an ignition device, a gasification region, a drying region and an ash collecting chamber. The upper part of the furnace body fire grate is a gasification area, the upper part of the gasification area is a drying area, a conical fireproof concrete structure is arranged between the gasification area and the drying area, namely a conical blanking cavity is formed, and the cone angle of the conical blanking cavity is minus degree, preferably about degree, so that the materials can fall automatically and uniformly. The diameter of the gasification area is designed after calculation of gasification strength, so that the gasification quality of the material is ensured. Two cleaning doors are arranged on the gasification area, so that carbon dust can be conveniently cleaned after gasification. An ignition chamber is arranged at the lower part of the gasification region, and a sealing door is arranged on the ignition chamber for timely sealing after ignition. A magnetized air inlet is arranged in the ignition chamber, and magnetized air generated by the air magnetization oxygen supply device enters through the magnetized air inlet; the ignition chamber is connected with an oxygen supply ignition device, and the oxygen supply ignition device is provided with a jet hole. When ignition, the flame generated in the ignition chamber is sprayed out through the spray holes to ignite the gas material, and after the material in the ignition chamber is burnt out, the magnetized air is sprayed out through the spray holes to supply magnetized oxygen to the gasification area.

The upper part of the ignition chamber is provided with a gasification temperature detection device interface, the running temperature of the gasification area is detected through a thermocouple, the revolution of the blower is controlled, and the gasification temperature control of the gasification area is realized. The lower part of the gasification zone is also provided with a movable grate which is fixed on a partition plate at the lower part of the gasification zone, the partition plate is provided with a grate fixing ring, and the movable grate is embedded on the grate fixing ring; the grate is a swing type grate and comprises a plurality of shaft rods and wing rods which are fixedly connected to two sides of the shaft rods in a distributed mode, the wing rods are distributed in a staggered mode, and the shaft rods are driven by a connecting rod mechanism and a handle outside the furnace body to rotate and swing so as to disturb ash residues on the grate, enable the ash residues to fall down and adjust the ventilation condition of the grate.

The gasification zone is matched with the grate to ensure that the gasification agent flowing upwards through the grate is uniformly distributed, so that the temperature of the oxidation zone on the grate is uniform, and local fire leaping is not generated, so that the temperature distribution of the reduction zone and the pyrolysis zone is uniform, the stable gasification of materials by the oxidation zone, the reduction zone and the pyrolysis zone is facilitated, and the control and the stable gasification strength are facilitated.

In addition, the height from the upper surface of the grate to the upper end of the gasification zone, i.e., the gasification (generation) zone, is a key factor in controlling the temperature of the oxidation zone, the reduction zone, and the pyrolysis zone. The higher the gasification zone is, the thicker the material layer is, and the lower the temperature of the upper reduction zone and pyrolysis zone is. If the temperature of the reduction zone and the pyrolysis zone is increased, the fire grate must be increased, the materials are burnt at high temperature, and the decomposed combustible gas is greatly reduced. Through a large number of tests, the height of the gasification zone is 650-. And the temperature range effectively avoids the generation temperature of the hanging reaction of the dioxin at the temperature of 600-800 ℃, and effectively limits the generation of the dioxin.

In addition, the gasification (generation) area represented by the gasification area in the magnetization pyrolysis gasification furnace is reasonable in structure and parameter design, and simple and convenient to operate, and especially, the gasification of combustible garbage can be realized by taking magnetized air as a gasification agent without adding auxiliary raw materials, so that the gasification efficiency is improved, and the gasification effect is good.

The flange inlet of the air magnetization oxygen supply device is connected with a high-pressure blower. The high-pressure blower is connected with the automatic control device, and the revolution is controlled by the temperature signal of the gasification zone, namely the temperature of the gasification zone is controlled by the oxygen supply amount, so that the gasification quality is ensured.

Air is sent into the air magnetizer through the blower, enters from the inlet flange end and flows out from the outlet flange end, the passing air is magnetized by a strong magnetic field formed between the strong magnetic sheets installed in pairs, the magnetized air is adjusted and controlled through the air volume adjusting valve and is input into an ignition chamber of the magnetization pyrolysis gasification device through the check valve to be sprayed into a gasification area through a jet hole on the oxygen supply ignition device to supply gasification oxygen.

The working principle of the invention is as follows:

although oxygen is a molecule with even number of electrons, it still has stable inherent magnetic moment, and is a paramagnetic substance with high magnetic susceptibility. When the external magnetic field is zero, the molecular magnetic moments are randomly oriented due to the effect of thermal temperature. Under the action of an external magnetic field, the magnetic moment of the molecule is oriented along with the external magnetic field, and the polarity of the molecule tends to be parallel to the external magnetic field and enhances the magnetic field. After the oxygen in the air is magnetized, the activation energy is greatly improved. Thus, the amount of air introduced into the magnetization pyrolysis gasification generator 1 can be as small as the partial combustion cannot be maintained without magnetization. After magnetization, the stable partial combustion can be maintained, the air quantity used for burning the garbage is reduced, the burning smoke generated by burning can be reduced, and the burning dust is reduced. In particular, the specially treated magnetized air entering the generation zone can also indirectly magnetize the treated solid waste, and the intermolecular cohesion among organic components in the treated solid waste is reduced under the action of magnetic energy, thereby improving the pyrolysis effect. In addition, since the amount of air introduced is small, the occurrence zone maintains a low pyrolysis temperature (less than 500 ℃) during normal stable pyrolysis. It is known that a large amount of dioxin is rapidly generated (0.1 to 0.2s) at an incineration temperature of 550 to 700 ℃. In an environment of 300 ℃, the concentration of dioxin mainly depends on the content of oxygen, the concentration of the dioxin in an oxygen-deficient environment is reduced, and no dioxin is generated without oxygen. Because the magnetized air indirectly magnetizes the processed materials, the energy required by pyrolysis is reduced, and the pyrolysis efficiency is improved, so that the pyrolysis gasification can be realized at a low temperature of 300 ℃, and the generation of dioxin is basically avoided. Moreover, the pyrolysis process does not need any energy source, so the method is a new environment-friendly and energy-saving technology.

The working process of the invention is as follows:

collecting domestic garbage, breaking bags, and sorting out incombustible large bricks and stones in the domestic garbage, if the water content of the garbage exceeds 30%, air drying or oven drying the garbage to reduce the water content of the garbage as much as possible, preferably not more than 30%.

With the implementation of the national household garbage classification policy, household garbage produced by rural residents is combustible garbage after household classification, the water content is reduced, the gasification technical requirement condition is completely met, the garbage can be locally and nearby treated at the same day, and the household garbage degradation hazard is avoided. And the production of the transportation cost of the household garbage is reduced.

The combustible domestic garbage is uniformly fed into the top feed inlet sealing door of the magnetization pyrolysis gasification generator by a feeder, and the materials are combusted, pyrolyzed (dry distilled) and gasified in an anaerobic state to prepare combustible gas. After entering the air magnetizing device for magnetization treatment through the blower, the gasifying agent (air) enters the ignition chamber of the magnetization pyrolysis gasification device through the flow regulating valve and the check valve, and is sprayed into the gasification area through the jet hole on the oxygen supply ignition device for magnetization pyrolysis gasification of the combustible garbage, and the combustible garbage is made into fuel gas through four processes of drying, pyrolysis, reduction and oxidation, and is discharged through the air outlet and used as fuel for boilers and the like or directly enters the combustor for combustion treatment. The flowing direction of the air flow in the magnetic pyrolysis gasification device is opposite to the moving direction of the materials moving downwards, and the materials moving downwards are dried by the hot gas flowing upwards to remove moisture. The dry materials enter the pyrolysis zone to obtain more heat, and then cracking reaction is carried out to separate out volatile matters. The generated carbon enters a reduction zone and is subjected to reduction reaction with hot gas generated in an oxidation zone to produce combustible gas such as CO, H2 and the like. Carbon which is not consumed in the reaction enters an oxidation area for oxidative decomposition, and ash falls into an ash chamber. The oxidation zone of the present magnetization pyrolysis gasification apparatus 1 is located at the bottommost of the four reaction zones below the reduction zone. The hot carbon undergoes an oxidation reaction with the magnetized air entering the oxidation zone. The magnetized air can effectively break the macromolecular chain, reduce oxygen consumption, accelerate reaction speed and reaction quality and reduce ash yield. The mixed gas (i.e. combustible gas) produced in the oxidation zone, the reduction zone, the pyrolysis zone and the drying zone flows from bottom to top and is discharged out of the magnetization pyrolysis gasification device 1.
