Problems solved by technology

The temperature of the coke discharge smoke is high, the instantaneous thermal buoyancy and the amount of dust are large, but the area ratio of the bucket-type dust collection hood between the top of the coke holding car and the top of the coke quenching car is very different, and the suction of the ground dust removal fan is mainly allocated to the coke quenching The bucket-type dust collection cover on the top of the carriage, and there is a gap between the coke-guiding grid-covered bucket-type dust collection cover and the small burner, so part of the smoke escapes from the small burner.
In order to improve the dust removal effect, some coking enterprises adopt the method of opening holes on the side plate of the bucket-type dust collection cover near the furnace body on the top of the coke guide grid and attaching a vehicle-mounted fan to assist dust collection. Some enterprises adopt the method of adjusting the dust removal fan of the ground station to run at high speed in advance The time parameter is used to pre-increase the suction force of the red coke in the initial grid entry stage; but the results are not satisfactory, and the power consumption is also increased

Abstract

The invention discloses a bag type dust collector for a stamping coke oven. A support base is arranged on an oven top base line; a fan and a dust collector are fixed on the support base; the bag typedust collector further comprises a main air tube and a plurality of air collection covers; the air collection covers are arranged right above the outer sides of two adjacent coke side small oven burners in a covering manner; one end of the main air tube is communicated with the air sucking hole of the fan and the air inlet of the dust collector; the other end of the main air tube is communicated with the air collection covers through branch air tubes; the air collection covers consist of collection sections and refraction sections which are connected with each other; spiral grooves are formedin the inner walls of the collection sections in the axis directions of the collection sections; the refraction sections take the shape of a corn; the corn tip parts of the refraction sections are communicated with the tail ends of the branch air tubes. When the bag type dust collector is used, fume diffused out from the small oven burners on the oven top base line is centrally collected through the air collection covers simultaneously, the collected fume is fed into the main air tube through the branch air tubes and is fed into a dust filter under traction of the pneumatic power of the fan, then the fume is treated, fume is avoided from escaping from the top of the oven, and environmental pollution is avoided.

Description

technical field [0001] The invention relates to the technical field of coking and environmental protection, in particular to a bag-type dust collector for tamping coke ovens. Background technique [0002] Coking is a multi-source pollution industry, and smoke and dust are the main pollutant fugitives in the coking production process. Modern chamber coke ovens are generally equipped with vehicle-mounted or ground station coal charging and coke discharge dust removal systems, of which the ground station dust removal system is widely used. The ground station type coke discharge dust removal system mainly uses hydraulic coupling or frequency conversion control fans to collect most of the smoke dust on the coke side through the collection cover set on the coke stop car and purifies it through the coke discharge dust collector. However, part of the smoke and dust still escapes from the small burner head on the coke side, which deteriorates the working environment. The coke disch...
