Coke oven gas lower spray pipe brick gas duct full-slurry grouting sealing system and method

Abstract

The invention discloses a coke oven gas lower spray pipe brick gas duct full-slurry grouting sealing system and method, and relates to the technical field of coke oven thermal state engineering. The system comprises a slurry spraying pipe, a slurry spraying tank, a slurry return tank and an air compression system, the slurry spraying pipe is arranged at the lower end of a brick gas channel, the slurry spraying pipe extends upwards into the brick gas channel and is in sealing connection with a lower spraying pipe four-way joint through a quick sealing joint, slurry in the slurry spraying tank is poured into the brick gas channel through an air compression system, and the amount of the slurry in the slurry spraying tank is configured to enable the height of the slurry poured into the brick gas channel to be 50 mm higher than the upward position of a horizontal brick joint of a top-layer gas channel pipe brick in the brick gas channel. By means of the technical scheme, the one-time full-height integral grouting sealing effect can be achieved by controlling the slurry amount, the grouting sealing quality of the coke oven gas down-spraying pipe brick gas channel is improved, the construction period is shortened, the construction cost is reduced, the subsequent repairing procedures of the brick gas channel can be effectively reduced, the construction cost is reduced, and a high use and promotion value is achieved.

Description

technical field [0001] The invention relates to the technical field of thermal state engineering of coke ovens, in particular to a grouting sealing system and method for coke oven gas downspray brick gas channel full grouting method. Background technique [0002] After the construction of the coke oven cold state project is completed, before the coke oven production is used, the coke oven body heat state project is carried out, the coke oven body is heated and dried, and the furnace body is heated and dried to reach the high temperature of the coke oven body In use state, coke oven production can be carried out. The brick gas channel is the channel through which the coke oven gas enters the coke oven from the gas nozzle to burn, so that the coke oven gas enters the combustion chamber through the brick gas channel to provide heat for the coke oven production; the brick gas channel is composed of specific types of refractory bricks and When the coke oven body is baked in a ho...

AI Technical Summary

Problems solved by technology

The brick gas channel is the channel through which the coke oven gas enters the coke oven from the gas nozzle to burn, so that the coke oven gas enters the combustion chamber through the brick gas channel to provide heat for the coke oven production; the brick gas channel is composed of specific types of refractory bricks and It is built with clay ash. When the coke oven body is baked in a hot state before the start of construction, the coke oven masonry expands, resulting in cracks in the refractory mud between the bricks, resulting in cracks in the bricks of the lower nozzle brick gas channel , Brick cracks will cause gas leakage during coke oven production, which will seriously affect the temperature and production of the coke oven combustion chamber, which will seriously affect the safe production of the coke oven regenerator
