Compact type collection device and method for dissipated smoke dust of coke oven

Abstract

The invention relates to a compact type collection device and method for dissipated smoke dust of a coke oven. The device comprises a smoke dust collecting hood and a wind-proof adjusting device, wherein the smoke dust collecting hood is arranged above the coke oven, and the projection area of the smoke dust collecting hood covers the projection area of the coke oven and is larger than the projection area of the coke oven; a flue gas conveying pipeline is arranged at the central part of the top of the smoke dust collecting hood; the wind-proof adjusting device is arranged in an annular space between the periphery of the top of the coke oven and the smoke dust collecting hood, and comprises a wind shield and an air quantity adjusting mechanism; a plurality of air holes are formed in the wind shield; and the air quantity adjusting mechanism is used for adjusting the perforation rate of the wind shield. By combining a flowing characteristic of gas at the periphery of the coke oven and adopting a method matching the smoke dust collecting hood with the wind-proof adjusting device, the aim of efficiently collecting long-period, small-quantity, irregular, multi-sourced and occasional dissipated smoke dust on oven doors at two sides of machine coke, an ascending pipe gap, a furnace-top coal filling hole, a fire observation hole and the like in a production process of the coke oven is achieved, and the environment is effectively protected.

Description

technical field [0001] The invention relates to the technical field of atmospheric pollutant emission control, in particular to a compact coke oven fugitive smoke collection device and 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
