Coke oven machine coke side oven door unorganized emission continuous collection technology

Abstract

The embodiment of the invention aims to solve the technical problems in the prior art, provides a coke oven machine coke side oven door unorganized emission continuous collection technology, which aims to solve the technical problems that in the coking production process, due to the characteristics of coke oven production, after coke oven coaling and in the coking process, high-pressure raw coke oven gas in a carbonization chamber breaks through an oven door cutter edge, or the raw coke oven gas in the carbonization chamber leaks from the untight sealing position of the oven door cutter edge, and generated unorganized emission is continuously collected.

Description

technical field [0001] The invention relates to the technical field of coking environmental protection, in particular to the continuous collection of fugitive emissions above the coke side oven door of the coke oven machine Background technique [0002] In the production process of coke ovens, the coke oven pushes coke and coal, etc., and produces a large amount of waste gas discharged from toxic dust-containing tissues, which contains solid suspended matter, benzene soluble matter, benzopyrene, hydrogen sulfide, ammonia and other harmful substances, such as Long-term exposure is very harmful to human health. According to the analysis of the amount of harmful substances contained in the three types of smoke and dust emission sources (continuous, array and accidental) in the coke oven production process, the emission of coke oven smoke and dust is the largest, and the most harmful thing is the large amount of spilled during the coal charging process. Coarse gas and soot acco...

Problems solved by technology

[0013] 2. Smoke generated during the coking process

[0015] 1) The smoke and dust generated by the poor sealing of the coke oven door;

[0016] 2) The smoke and dust generated by the poor sealing of the coke oven cover;

[0017] 3) The smoke and dust generated by the unsealed coke oven riser cover;

[0019] 5) Black smoke emitted from the chimney due to coke oven leakage;

[0020] 6) The lack of coke oven heating system leads to black smoke from the chimney

Within 4 hours after the coke oven is charged to coking, it is in the initial carbonization time, the amount of gas generated in the carbonization chamber is large, and the flow area of ​​the raw gas in the coke oven is fixed, resulting in high pressure in the coke oven carbonization chamber and serious smoke. Unorganized emissions, with the increase of thermal buoyancy, not only pollute the environment, but also cause harm to the personal health of coke oven operators

[0026] This kind of unorganized emission is caused by the characteristics of coke oven production. Under the conventional coking operation, there is no way to collect and treat it. It is not allowed by the current environmental protection, occupational health and other work. There is an urgent need for a method that can collect and treat this kind of waste.
