Abstract

The invention provides a method for dismantling a coke oven column and a protection plate. The method is characterized by including the following steps that a, preparation work is done for dismantlingthe coke oven column and the protection plate; b, a coke oven machine, an oven column on the coke side and the protection plate are dismantled at the same time; c, before the coke oven column and theprotection plate are dismantled, the coke oven machine and springs of an upper cross brace and a lower cross brace on the coke side are subjected to pressure relief; d, before the coke oven column and the protection plate are dismantled, the coke oven machine, and a big spring and a big spring baffle on the upper cross brace on the coke side are fixed; e, the protection plate is assembled and a lifting point is set; f, the oven column, a protection plate hoist, the coke oven machine, the oven column on the coke side and the protection plate need to be dismantled and hoisted at the same time.The method for dismantling the coke oven column and the protection plate has the advantages that the design of dismantling steps is reasonable, the operability is high, the demolition project is safeand reliable, the coke oven column and the protection plate can be quickly dismantled, the labor intensity is reduced, the construction period is shortened, the construction cost is saved, the projectcost is reduced and economic benefits are remarkable.

Description

technical field [0001] The invention relates to an industrial kiln overhaul, in particular to a method for removing a coke oven column and a protective plate. Background technique [0002] At present, there are more than 100 coke ovens in my country that are in the middle and late stages of their service life. As time goes by, more and more coke ovens need to be dismantled. The structure of the coke oven is complex and there are many holes. There are various connection forms between the iron parts of the coke oven and the masonry of the coke oven. The construction safety risks are high, the construction period is long, and the cost of measures is high. [0003] Therefore there are above-mentioned inconveniences and problems in the known coke oven column, protective plate removal mode. Contents of the invention [0004] The object of the present invention is to propose a fast and safe method for removing coke oven pillars and protective panels. [0005] For realizing the...
