Repairing protection apparatus of coke oven charing chamber, production method thereof and repairing method of charing chamber

Abstract

The invention discloses a repairing protection apparatus of a coke oven charing chamber, a production method thereof and a repairing method of the charing chamber, the repairing protection apparatus comprises an inner side thermal insulation board arranged in the charing chamber and comprises furnace wall heat insulation combination plates arranged on the furnace wall at two sides of the charing chamber, the furnace wall heat insulation combination plates on the furnace wall at two sides are respectively connected to two ends of the inner side thermal insulation board; a gap with size bigger than that of metope of furnace wall and used for repairing is arranged on the furnace wall heat insulation combination plate positioned at furnace wall side to be repaired; and the repairing protection apparatus also comprises a top heat insulation combination plate arranged over the heat insulation combination plate and a bottom heat insulation structure paved at bottom of the charing chamber. According to the invention, the furnace wall repairing can be carried out under high temperature of 700-800 DEG C which is kept in a combustion chamber, damage of repairing at low temperature on a furnace can be avoided, repairing time can be shortened, repairing efficiency is increased; repairing effect can be ensured, service life of coke oven is increased, and coke output and quality can be ensured.

Description

technical field [0001] The invention relates to coke oven maintenance technology, in particular to a coke oven carbonization chamber repair protection device, a manufacturing method thereof and a carbonization chamber repair method. Background technique [0002] During long-term production and use, the coke oven is damaged due to high temperature, mechanical force, physical and chemical reactions, etc. The damage is mainly manifested in wall erosion, furnace wall cracks and holes, and furnace bottom brick cracking and wear. When the furnace wall of the carbonization chamber is damaged, and the hole in the furnace wall of the carbonization chamber is large and far away from the furnace mouth, repair personnel need to enter the interior of the carbonization chamber for repair. However, due to the high temperature in the carbonization chamber and the lack of good heat insulation protection measures, people cannot enter the repair area. Therefore, the temperature of the combusti...

Problems solved by technology

This will cause great damage to the coke oven and affect the service life of the coke oven

[0004] On the other hand, due to the long cooling and heating time before and after the repair of the carbonization chamber, the repair efficiency is low, and more abnormal furnace numbers are generated, which disrupts the normal production sequence and affects the coke output and quality
