Treatment device for pollution gas generated by coke oven

Abstract

The invention provides a treatment device for pollution gas generated by a coke oven. The treatment device is composed of a foundation, a closed bin, overhaul riding tracks, a roof system, ventilationsystems, a gas purification system, a system for dust suppression through spraying, a fire extinguishing system, a monitoring system, a lighting system and a drainage system. The closed bin is arranged on the foundation; the roof system is mounted on the outer surface of the closed bin; the ventilation systems are arranged at the lower part and the top of the closed bin; the gas purification system is arranged in the closed bin; the overhaul riding tracks are installed on the two sides of the top of the closed bin; the system for dust suppression through spraying is arranged on the ground inthe long side direction of the closed bin; the fire extinguishing system, the monitoring system and the lighting system are installed on two sides of the top of the closed bin and located below the overhaul riding track; and the drainage system is located around the bottom of the closed bin. The device has complete functions, can effectively treat a large amount of dust and gas produced by the coking industry, is free of the hidden danger of paroxysmal and unorganized emission, and improves environment and working conditions.

Description

technical field [0001] The invention belongs to the field of environmental protection, and is mainly used for treating polluted gas produced in coking industry, and in particular relates to a treatment device for polluted gas produced by coke ovens. Background technique [0002] Most of the coke oven coking facilities at home and abroad are composed of coke oven body, coke pushing car on the machine side, coke holding car on the coke side, coke tank car, coal loading car, coke discharge and dust collection interface valve, etc. Coke oven auxiliary machinery is operated in the open air. The coking plant will produce a large amount of dust and gas in the process of coking, coke screening, coking and chemical production, which are intermittent and unorganized emissions. The main pollutants are: particulate matter, benzene soluble matter, benzo(a)pyrene , H2S, NH3, etc. Wet coke quenching is that the coke is sent into the coke quenching tower, and the water is in contact with ...

AI Technical Summary

Problems solved by technology

Although the single-point amount of these smoke dusts is very small, because there are many escape points and they cannot be collected effectively, a large part of the smoke dust will still enter the atmosphere and cause damage to the environment.

In addition, the soot collection rate of the above-mentioned several dust removal facilities often cannot reach 100% in the early and late stages of work, resulting in a small amount of soot escaping into the atmosphere. The long-term accumulated fugitive soot emission is still an important factor of environmental pollution
