Coke oven chute opening adjusting structure

Abstract

The invention relates to a coke oven chute opening adjusting structure which comprises an adjusting brick and an adjusting brick groove; the adjusting brick groove is formed in one side or two sides of the chute opening, and a fulcrum beam protruding upwards is arranged between the adjusting brick groove and the chute opening; when the chute opening is adjusted, an adjusting tool extending into the chute opening from the upper portion of the corresponding vertical flame path is used for operation, the adjusting tool is used for pressing one end, corresponding to the chute opening, of the adjusting brick or one end, corresponding to the adjusting brick groove, of the adjusting brick according to needs, the adjusting brick rotates around the fulcrum beam, and when the corresponding end of the adjusting brick falls into the adjusting brick groove, the other end of the adjusting brick is lifted up, the chute opening is in an open state; when the corresponding end of the adjusting brick falls above the chute opening, the chute opening can be covered; the sectional area of the gas channel of the chute opening is changed by adjusting different states of the brick, so that the purpose of adjusting the gas flow and pressure in the coke oven is achieved.

Description

technical field [0001] The invention relates to the technical field of coke ovens, in particular to a coke oven chute opening adjustment structure. Background technique [0002] The body of the coke oven is mainly composed of a carbonization chamber, a combustion chamber, a regenerator, a chute and a roof area. The chute is located on the upper part of the regenerator and the lower part of the combustion chamber, and is a passage connecting the regenerator and the combustion chamber. The air and gas in the regenerator enter into the vertical fire channel of the combustion chamber through the ramp to burn. [0003] The reheating coke oven can be heated by coke oven gas with high calorific value, or blast furnace gas or mixed gas with low calorific value. When coke oven gas is used for heating, the two regenerators corresponding to the same combustion chamber are fed with combustion-supporting air at the same time; when blast furnace gas is used for heating, one regenerator i...

Problems solved by technology

[0004] The adjustment accuracy of the cross-sectional area of ​​the airflow channel at the coke oven chute is directly related to the quality of the coke maturation. At present, most of the hooks are used to increase or decrease the adjustment brick to roughly change the cross-sectional area of ​​the airflow channel at the chute, and then change the heating gas flow and The disadvantage of the heating system is that the gas flow cannot be adjusted accurately and quantitatively, so the heating system is difficult to meet the design requirements, which affects the normal production of the coke oven
