Coke oven carbonization chamber structure capable of reducing smoke emission

Abstract

The invention relates to a coke oven carbonization chamber structure capable of reducing smoke emission. A roof-spanning brick is arranged at the top of a carbonization chamber, and a carbonization chamber top space between the roof-spanning brick and a coal charging line is a furnace top space; and two sides of the furnace top space respectively extend outwards to form groove structures, so that the width of the furnace top space is greater than that of the carbonization chamber. According to the invention, the raw gas circulation sectional area of the furnace top space of the carbonization chamber is enlarged, the pressure in the carbonization chamber at the initial stage of coaling is reduced, and the escape of raw gas and smoke dust can be effectively reduced on the premise of not influencing the high maturity of the coke cake.

Description

Technical field [0001] The present invention relates to the field of coke oven, in particular, to a coke oven carbon chamber structure to reduce dust discharge. Background technique [0002] In the large coke oven, the coke oven body is composed of a heat storage chamber, a ramp, a combustion chamber and a carbonization chamber, a pocket top, and the top of the carbonized chamber is disposed, the top brick is provided, the top is provided in the top (pointing coke In the case, the tamper coke furnace is set to a conduit aperture and a carbon hole) and a rising tube hole. In the carbonization chamber, the area between the coalted line and the cross-top bricks determined by the coal is referred to as the cortical gas and smoke generated in the roof space, coal, and the coalflight generated by the roof space and the coal air flow space introduction. Go to the rising tube, then export the coke oven by the rising tube. The height of the roof space is an important parameter in the desi...

AI Technical Summary

Problems solved by technology

Due to the short-term generation of a large amount of gas in a limited space, the air pressure in the top space of the carbonization chamber is relatively high at this time, resulting in smoke and fire at the furnace roof and furnace door during coal charging, flat coal, and early coking, causing environmental pollution and Potential safety hazards, but also seriously deteriorated the environment of the furnace top operation area

[0004] In order to reduce the phenomenon of waste gas and dust escaping during coal charging, the existing coke ovens are generally equipped with high-pressure ammonia water combined with a coal charging dust removal system or a carbonization chamber pressure monotonous system, but the actual use effect on site is not ideal. There will still be raw gas coming out of the roof and furnace door
