Abstract
The coke-oven flue gas purification system is characterized by that the flue gas spray condenser tube is connected with gas-liquid separator and washing twoer in turn, the flue gas output end of washing tower is connected with fan, and communicated with chimney, and the liquid of gas-liquid separator is fed into tar ammonia water clarifier-tank, the input end of the pump is communicated with the tar ammonia water clarifier-tank, and its output end is communicated with flue gas spray condenser tube, the input end of pump is communicated with clear water pool, and its output end is communicated with washing tower. It can effectively remove black smoke, granular substance being in yellow smoke, sulfur dioxide, benzo(a) pyrene and Ringlemann blackness so as to make the flue gas attain the discharge standard.
Description
The present invention relates to a kind of flue gas purification system that is applicable to the on-mechanical coke oven.
In the prior art, the on-mechanical coke oven self exists a lot of shortcomings, wherein the flue gas that is most importantly produced during coking directly enters atmosphere by chimney, particulate in air, sulfur dioxide, benzo (a) pyrene and lingemann blackness severe overweight have been caused, in this zone almost every day all by smogout, the people that make in this area life suffer from respiratory system and circulation system disease to some extent, have seriously influenced people's physical and mental health.
The purpose of this invention is to provide a kind of flue gas purification system that is used for the on-mechanical coke oven, the black smoke that it can efflux chimney, the particle in the tobacco, sulfur dioxide, benzo (a) pyrene and lingemann blackness are able to effective removal, thereby reach discharge standard.
For achieving the above object, the present invention has adopted following technical scheme: cock-oven gas purifying system mainly comprises flue gas spray condenser pipe (1), gas-liquid separator (2), scrubbing tower (3), blower fan (4), tar ammonia depositing reservoir (7), pump (6).Its concrete structure is such: flue gas spray condenser pipe (1) is connected with gas-liquid separator (2), scrubbing tower (3) successively, the flue gas output (11) of scrubbing tower (3) is connected with blower fan (4), and communicate with chimney (9), the liquid of gas-liquid separator (2) enters tar ammonia depositing reservoir (7), and the input of pump (5) communicates with tar ammonia depositing reservoir (7); Output communicates with flue gas spray condenser pipe (1), and the input of pump (6) communicates with clear water reserviors (8); Output communicates with scrubbing tower (3), and the liquid output (15) of scrubbing tower effluxes.
Characteristics of the present invention are: (1) is because the on-mechanical cock-oven gas purifying system can make the fume emission particle reduce to 280mg/m
3(mark attitude), ton burnt 3.2kg/t (Jiao); Sulfur dioxide is reduced to 450mg/m
3(mark attitude), ton burnt 5.3kg/t (Jiao); Benzo (a) pyrene is reduced to 1.80mg/m
3(mark attitude), ton burnt 0.018kg/t (Jiao); 1 grade of lingemann blackness ∠ meets the specification requirement to on-mechanical coke oven Air Pollutant Emission fully.(2) because the on-mechanical coke oven adopts this cleaning system, not only protected environment, the tar that contains a large amount of benzo (a) pyrene has been reclaimed, for enterprise has also created considerable economic.(3) compliance with environmental protection requirements, useful people's is healthy, has good social benefit and high promotional value.
The present invention is described in further detail below in conjunction with specific embodiment and accompanying drawing.
Fig. 1 is a process chart of the present invention.
With reference to Fig. 1, flue gas spray condenser pipe 1 is connected with gas-liquid separator 2, scrubbing tower 3 successively, and the flue gas output 11 of scrubbing tower 3 is connected with blower fan 4, and the flue gas output 12 that is provided with absorber 10 absorbers 10 between blower fan 4 and chimney 9 communicates with chimney 9; Liquid output 13 communicates with tar ammonia depositing reservoir 7.The liquid of gas-liquid separator 2 enters tar ammonia depositing reservoir 7, and the input of pump 5 communicates with tar ammonia depositing reservoir 7; Output communicates with flue gas spray condenser pipe 1, and the input of pump 6 communicates with clear water reserviors 8; Output communicates with scrubbing tower 3, and the liquid output 13 of absorber 10 communicates with tar ammonia depositing reservoir 7, and the liquid output 15 of scrubbing tower effluxes.Be equipped with several shower nozzles on cylindrical circular flue gas spray condenser pipe 1 and the scrubbing tower 3.Operation principle of the present invention is: thus the on-mechanical coke oven is by self sucking the coal combustion heating another part coal of air in certain amount with a part, making it become coke.Therefore exist coal dust in discharged flue gas, a dust and a part be because the tar that the dry distillation of coal produced etc., its polluter particle, sulfur dioxide, benzo (a) pyrene and lingemann blackness severe overweight.Native system is to adopt water that the flue gas that is produced is lowered the temperature, washed, repeatedly purify then, gas-liquid separation, thereby the pollutants such as tar that produced in the coal dust in the removal flue gas, dust and the destructive distillation, thereby the particle in the reduction flue gas, sulfur dioxide, benzo (a) pyrene and lingemann blackness.The course of work is: after flue gas 14 is drawn by on-mechanical coke oven main chimney flue, be introduced into flue gas spray condenser pipe 1, flue gas is cooled off; Enter gas-liquid separator 2 then, gas separated is separated with liquid, liquid enters tar ammonia depositing reservoir 7 to be separated again, gas enters scrubbing tower and washs again, enter blower fan 4 then, enter absorber 10 again and carry out final purification, the gas that has purified is discharged by chimney 9.Liquid then carries out layering in tar ammonia depositing reservoir 7, the upper strata is an ammoniacal liquor, is squeezed into by pump 5 to recycle lower floor's tar in the flue gas spray condenser pipe 1 and can be used as product and sell.Flue gas carries out secondary washing in scrubbing tower 3; After flue gas entered absorber 10, the separated back of liquid flowed into tar ammonia depositing reservoir 7.
