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

Abstract

The invention provides a flue gas centralized 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 aSCP all-in-one machine, and comprises a coal charging smoke dust collection pipeline, a detachable coal charging furnace opening smoke collection cover, a coal charging pipeline valve plate, a coke pushing smoke dust collection pipeline, a coke pushing pipeline valve plate, a coke pushing collection cover, a door cleaning smoke dust collection pipeline, a door cleaning pipeline valve plate, a smoke dust collection main pipeline, a collection main pipeline valve plate, air plates and a ground dust removal pipeline; smoke and dust are collected in a segmented mode through an area formed after the multiple air plates are fixed, and meanwhile it is avoided that external natural air influences the area in front of the furnace. Then the smoke collection cover is adopted to collect the flue gas,so that the SCP all-in-one machine collects the amount of smoke at a furnace mouth in the processes of coaling, coke pushing, door cleaning, car moving and coal cake cutting; the environmental protection level of the whole SCP all-in-one machine is improved, and the market competitiveness and economic benefits of group company products are remarkably enhanced.

Description

technical field [0001] The invention relates to the technical field of metallurgical coking, in particular to a centralized flue gas 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 and coke pushing machine (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. Somewhat deficient,...

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

In the actual production process, this smoke and dust control method can only solve the smoke and dust problem in the coal loading process, but cannot solve the smoke and dust problem in the process of pushing coke, clearing the door, moving the car, and cutting coal cakes, and the natural wind outside will affect the smoke collection at the furnace mouth Effect
