Coke side small furnace end smoke treatment device

Abstract

The invention discloses a coke side small furnace end smoke treatment device. A supporting base is arranged on a furnace top base line, and a draught fan and a dust remover are fixed to the supporting base. The coke side small furnace end smoke treatment device further comprises a main gas pipe and a plurality of gas collecting hoods. The position above the outer sides of two adjacent coke side small furnace ends is covered with the gas collecting hoods. One end of the main gas pipe is communicated with an exhaust inlet of the draught fan and an air inlet of the dust remover, and the other end of the main gas pipe is communicated with the gas collecting hoods through a branched smoke pipe. Each gas collecting hood is composed of a collection section and a refraction section which are connected, wherein a spiral groove is formed in the inner wall of the collection section in the axis direction, the refraction section is conical, and the conical tip part of the refraction section is communicated with the tail end of the branched gas pipe. During working, the gas collecting hooks centrally collect smoke spread out of the small furnace ends on the furnace top base line at the same time, and the collected smoke enters the main gas pipe through the branched gas pipe and enters a dust filter under the traction of wind force of the draught fan so that smoke can be treated, dissipation of smoke on the furnace top can be eradicated, and environment pollution can be avoided.

Description

technical field [0001] The invention relates to the technical field of coking and environmental protection, in particular to a flue gas treatment device for a coke-side small burner head. 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. T...

AI Technical Summary

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
