Coke oven chute cleaning technology

Abstract

The invention relates to a coke oven chute cleaning technology, which belongs to the coke oven assistant technology. The coke oven chute cleaning technology is characterized in that a glass mirror which is provided with a support and can adjust the mirror angle is vertically arranged on a chute inlet between a coke oven regenerator and a combustion chamber; the mirror surface of the glass mirror faces to the inside of the chute; when a furnace building worker enters into the coke oven chute for cleaning, the furnace building worker uses a cold-light source to irradiate the fa.ade of the glass mirror and simultaneously continuously adjusts the angle of the mirror surface until the reflected light of the glass mirror surface irradiates the inner wall of the chute and particularly irradiates the corner of the chute, and then fixes the glass mirror; and then the furnace building worker or a cleaner holds a tool to completely scrape residual slurry and other sundries on the inner wall of the chute, uses the reflected light of the glass mirror surface to reexamine until the chute is completely cleaned. Therefore, the cleaning work is quick and labor-saving and the chute is completely cleaned, consequently the masonry quality of a coke oven is guaranteed.

Description

technical field [0001] The invention belongs to coke oven auxiliary technology, in particular to a cleaning technology for large or super-large coke ovens. Background technique [0002] In existing coke ovens, especially in large and extra-large coke ovens, the chute is the channel connecting the regenerator and the combustion chamber, in which thousands of chute holes and gas passages are distributed, responsible for supplying air, gas and discharging The function of exhaust gas is a very important area in coke oven production, so the cleaning of the coke oven chute after masonry construction is particularly important. However, at the corner of the coke oven chute, people cannot directly see the waste gas on the chute wall. Compressed air is usually used to clean the chute for residual mud and debris, but it is difficult to clean it thoroughly, which is labor-intensive and time-consuming, and affects the construction quality of the coke oven.
