Flue gas dispersion treatment device applied to tamping coal charging coke pusher and using method thereof

Abstract

The invention provides a flue gas dispersion treatment device applied to a tamping coal charging coke pusher. The device is integrally arranged on the side, in butt joint with the furnace body, of a SCP all-in-one machine. The device comprises a coal charging smoke dust collecting pipeline, a detachable coal charging furnace opening smoke collecting cover, a coal charging pipeline valve plate, a coke pushing smoke dust collecting pipeline, a coke pushing pipeline valve plate, a coke pushing collecting cover, a door cleaning smoke dust collecting pipeline, a door cleaning pipeline valve plate,a vehicle-mounted dust remover, a vehicle-mounted dust remover valve plate, a wind shield and a ground dust removing pipeline. A coal cake cutting dust removal opening is located in the coal chargingsmoke dust collecting pipeline, and the coke pushing, door cleaning, and coal charging smoke dust collection pipelines and the ground dust removing pipeline are connected. The valve plates are additionally arranged on the smoke dust collecting pipelines, the valve plates of the dust removing pipelines are opened / closed in a delayed mode, the air amount is increased, the concentration of mixed gasis diluted, and the deflagration situation of smoke dust with different components is avoided.

Description

technical field [0001] The invention relates to the technical field of metallurgical coking, in particular to a flue gas dispersion treatment device applied to a tamping coal charging coke pushing machine and a method for using the same. Background technique [0002] With the sustainable development of the country, the country pays more and more attention to the comprehensive utilization of resources. A certain amount of low-quality coal can be blended in tamping coking coal blending to replace high-quality coal for coking, so the coking cost of tamping coal is low, and the quality of coke can be improved under the same coal blending conditions. Tamping coke oven machinery is currently the mainstream product of domestic coking equipment. [0003] The tamping coal charging coke pusher (SCP all-in-one machine for short) is a large-scale integrated tamping coke oven machine, which has the functions of tamping, coke pushing, and coal charging. It is highly automatic and efficie...

AI Technical Summary

Problems solved by technology

[0004] 1. The furnace door on the side of the coke oven machine is opened. When cleaning the furnace door, there is tar on the furnace door, and the tar smokes due to high temperature;

[0005] 2. During the coke pushing process, due to the opening of the furnace door on the side of the machine, a large amount of high-temperature flue gas in the furnace will overflow;

[0006] 3. During the coal charging process, coal cakes enter the carbonization chamber to generate a large amount of raw gas, and when the raw gas flows out of the carbonization chamber, a large amount of smoke and dust overflows;

[0008] 5. In the process of coal loading, coal cake collapse is inevitable, and it is necessary to use a vehicle-mounted coal cake cutter to cut the collapsed coal cake, and then close the furnace door

The flue gas generated during the coke pushing process is mainly the high-temperature air in the carbonization chamber. If a dust removal system is used for the two, deflagration is likely to occur when they are mixed.
