Demolition and reconstruction method of coke oven body

Abstract

The invention discloses a demolition and reconstruction method of a coke oven body. The method is characterized by comprising the following steps: a, preparatory work before demolition of the coke oven body; b, protective measures; c, demolition of the coke oven body; d, cleaning and repair of a oven hearth plate and a lower spray pipe; and e, oven body construction and equipment mounting. The demolition and reconstruction method of the coke oven body has the advantages that the construction step design is scientific and reasonable, the operability is high, the coke oven body is subjected to demolition and reconstruction, construction safety is guaranteed, the construction period is shortened, the investment cost is reduced, and the economic benefits are remarkable.

Description

technical field [0001] The invention relates to an overhaul of a coke oven kiln, in particular to a method for dismantling and rebuilding a coke oven body. Background technique [0002] At present, there are more than 100 coke ovens in my country that are in the middle and late stages of the furnace age. As time goes by, the coke oven masonry will become more and more aging, the refractory bricks will be seriously damaged, and the furnace wall will be deformed, denuded, perforated and other problems, resulting in coke pushing. Difficulties; the iron parts of the furnace protection were broken, and the seal with the body masonry was not tight, which caused a large area of ​​the coke oven body to emit smoke and fire during the production process, which seriously affected the production and failed to meet the environmental protection requirements. However, the original civil structures of the coke oven, such as the coal tower, inter-platform, coke oven foundation, resistance wal...

[0002] At present, more than 100 coke ovens in my country are in the middle and late stages of furnace age. As time goes by, the coke oven masonry will become more and more aging, the refractory bricks will be seriously damaged, and the furnace wall will be deformed, denuded, perforated and other problems, resulting in coke pushing. Difficult; the iron parts of the furnace are broken and the seal with the masonry of the main body is not tight, resulting in a large area of ​​smoke and fire in the coke oven main body during the production process, which seriously affects production and fails to meet environmental protection requirements
