Flow guide type coke oven leaking smoke collection device and method

Abstract

The invention relates to a flow guide type coke oven leaking smoke collection device and method. The device comprises a smoke collecting cover and a windproof adjusting device. The smoke collecting cover is arranged above a coke oven, the projection area of the smoke collecting cover covers and is larger than the projection area of the coke oven, and a flue gas conveying pipeline is arranged in the center of the top of the smoke collecting cover; the windproof adjusting device is arranged in an annular space between the periphery of the top of the coke oven and the smoke collecting cover, and comprises an air speed adjusting plate, an adjusting mechanism and a lower air flow baffle; a plurality of air holes are formed in the air speed adjusting plate, and the adjusting mechanism is used for adjusting the porosity of the air speed adjusting plate; a gap is reserved between the lower air flow baffle and the top of the coke oven. The collection device is combined with the flow characteristic of air flow around the coke oven, and the method in which the smoke collecting cover and the windproof adjusting device are matched with each other is used, so the aim of efficiently collecting long-time, little, irregular, multi-source and accidental leaking smoke at oven doors on the two sides of machine coke, riser seams, a coal charging hole in the oven top, an observation hole and the like is achieved, and the environment is effectively protected.

Description

technical field [0001] The invention relates to the technical field of air pollutant emission control, in particular to a diversion type coke oven fugitive smoke collection device and a collection method. Background technique [0002] In the field of metallurgical coking, the coke oven is an important equipment for the production of coke by coal dry distillation. At present, new coke ovens in coking plants at home and abroad are equipped with coal charging and coke discharge dust removal devices. These dust removal devices play a major role in the control of coke oven burst pollutant emissions. However, due to the large volume and complex structure of the coke oven, during the production of the coke oven, there are long-term, small, and irregular holes in the coke doors on both sides of the coke oven machine, the gaps in the riser pipe, the coal charging hole on the furnace top, and the fire viewing hole. , Multi-source, occasional smoke and dust escape. At present, in the...

Problems solved by technology

Although the concentration of dust pollutants is not large, its long-term cumulative pollution to the environment is still very serious

[0003] In addition, most of the coke ovens will experience abnormal conditions once or twice a year, that is, during the production of coke ovens, there may be excessive pressure in the riser pipe, accidental shutdown of the gas blower, and a large amount of gas release caused by other human factors. The mixed gas containing raw gas will escape in large quantities from the corresponding riser
