Device and method for collecting and purifying unorganized escaping waste gas of oven door of coke oven

The invention discloses a device and a method for collecting and purifying unorganized escaping waste gas of a coke oven door, wall-attached gas collecting branch pipes are arranged on two sides of the oven door to collect the unorganized escaping waste gas of the oven door, the waste gas is collected into a coaling dust removal waste gas header pipe through a gas collecting header pipe at the top, and organic pollution in the waste gas is adsorbed by activated carbon powder. And the waste gas is discharged after being dedusted, so that the problem of unorganized emission of the coke oven is solved, and meanwhile, huge investment and operation and maintenance costs caused by large-scale construction and transformation are avoided. 本发明公开了一种焦炉炉门无组织逸散废气收集净化装置及方法，通过在炉门两侧布置贴壁式集气支管收集炉门无组织逸散废气，并通过顶部的集气总管将废气汇入至装煤除尘废气总管，再利用活性炭粉吸附废气中的有机污染，废气之后经除尘后排放，从而解决焦炉无组织排放问题，同时避免由于大规模的施工改造而带来的巨额投资和运行维护成本。
