Technical field

The present invention relates to technical field of electric power, and in particular to a kind of coal steam-electric plant smoke processing method.

Background technique

International Organization for standardization (ISO) is to atmosphere pollution is defined as: " atmosphere pollution typically refer to due to mankind's activity and Natural process causes certain substance to enter in atmosphere, shows enough concentration, has reached time enough and has therefore endangered The comfortable of human body, health and wellbeing or the phenomenon that compromise environment."

In the range of atmosphere pollution occurs mainly in about 12km from the ground, drift about with atmospheric circulation and the movement of wind direction, It is that atmosphere pollution becomes a kind of flowing contact scar, with diffusion velocity is fast, spread scope is wide, the duration is long, it is big to cause damages The features such as.

The source of atmospheric pollution can be divided into natural and artificial two major classes.Natural pollution source is due to natural cause (such as volcano Outburst, forest fire etc.) and formed, man-made pollution source is to be engaged in production and life activity due to people and formed.Artificial dirty In dye source, and fixed (such as chimney, industrial exhaust gas cylinder) and two kinds of mobile (such as automobile, train, aircraft, steamer) can be divided into. Since man-made pollution source commonly and frequently exists, so being paid close attention to compared with natural pollution source come more people.Atmosphere master Pollution sources are wanted to have:

(1) industrial enterprise is one of main source and emphasis of atmospheric hygiene protected working of atmosphere pollution.With work The type and quantity of the rapid development of industry, atmosphere pollution are increasing.Due to the property of industrial enterprise, scale, technical process, Raw material and product category etc. are different, also different to the degree of atmosphere pollution.

(2) life cooking stove and heating boiler are in residential area, with the concentration of population, a large amount of domestic life cooking stove and adopt Heating boiler is also required to consume a large amount of coal, especially heating time in winter, often makes contaminated area full of smoke, this is also One kind cannot be neglected the source of atmospheric pollution.

(3) in recent decades, due to the development of transportation business, the automobile of city traveling is increasing, fire for communications and transportation The passenger and freight transportations such as vehicle, steamer, aircraft are frequent, these increase the new source of atmospheric pollution to city again.Wherein it is of great significance Be automobile discharge exhaust gas.The characteristics of auto-pollution atmosphere is that breathing zone of the pollutant away from people of discharge is close, can be directly It is sucked by people.Carbon monoxide, nitrogen oxides, hydro carbons (hydrocarbon), lead are mainly contained in the exhaust gas of car combustion engine discharge Compound etc..

The source of atmospheric pollution is divided into point source, face source, line source, four kinds of body source classification by the analog form of prediction mode.

Point source: the fixation point source of discharge, such as chimney, gas collecting jar with ground-on cover plate are concentrated by certain device.

Face source: it in certain area coverage, is discharged pollutants in a manner of short collection from ground or subaerial height Uncontrollable discharge, storage heap, cinder field emission source in source, such as technical process.

Line source: the linear discharge of pollutant or the source that linear discharge is made of moving source, such as the motor vehicle of urban road Emission source etc..

Body source: discharge pollutant to atmosphere in certain volume from the aerodynamic action in source itself or nearby buildings Source, such as coking furnace shaft, femerell.

Coal steam-electric plant smoke discharge is very big to atmospheric pollution effect, and the flue-gas temperature of thermal power plant is high, sets to fume treatment Standby requirement is very high, therefore, carries out effective processing to coal steam-electric plant smoke and is a problem to be solved.

Summary of the invention

The technical problems to be solved by the present invention are: providing a kind of coal steam-electric plant smoke processing method, solves the prior art The problem of middle coal steam-electric plant smoke emission treatment difficulty.

The present invention is achieved through the following technical solutions:

A kind of coal steam-electric plant smoke processing method, comprising:

Step 1: cooling device is arranged in the exit of heat-engine plant desulfurized tower, cigarette is set gradually in the outlet of cooling device Gas detection device and filter device, the filter device include filtering control device and filter；

Step 2: being cooled down by cooling device to the flue gas after desulfurization, it is cold to detect desulfurization by flue gas inspection device But smoke components, content after；

Step 3: filtering smoke components, the content controlling filter work that control device is detected according to flue gas inspection device Make.

Preferably, the filtering control device receives smoke components, the content information that flue gas inspection device detects, goes forward side by side Row processing issues control signal to filter according to processing result.

Preferably, the filtering control device can also show smoke components, content information.

The present invention has the advantage that and the utility model has the advantages that

1, cooling device is set first in the outlet of desulfurizing tower, then setting intelligent flue gas detects in the outlet of cooling device And filter device, cool down first to high-temperature flue gas, then targetedly flue gas is handled, so that the flue gas of discharge Requirement can be reached, reduce atmosphere pollution, while reducing the loss of fume treatment auxiliary.

2, filter setting is multistage, can effectively filter out heterogeneity, the harmful substance of different content, so that at flue gas That manages is more abundant.
