The technique problem to be solved is to provide the pressure regulating device for the coke oven carbonization chamber with facilitation of structure and convenience for operation and maintenance; the used technique scheme is as follows: the pressure regulating device for the coke oven carbonization chamber comprises an ascension pipe, a bridge pipe, a valve body, a valve disk, a regulating cylinder, a lifting mechanism and an air collecting pipe, wherein one end of the bridge pipe is connected with the ascension pipe, and the lower part of the other end of the bridge pipe is connected with the upper part of the valve body in a sealing manner; the lower end of the valve body is connected with the air collecting pipe; a guiding cylinder is installed in the bridge pipe, and is movably coated with the regulating cylinder inside; and the regulating cylinder is communicated with the bridge pipe and the valve body; a plurality of breaks are arranged on the periphery of the lower end of the regulating cylinder; the upper end of the regulating cylinder is connected with the lifting mechanism; the valve disk is installed under the regulating cylinder, and is located in the valve body, the ammonium hydroxide is in the valve disk, the breaks of the lower end of the regulating cylinder are completely immersed in the ammonium hydroxide in the valve disk; the pressure regulating device disclosed by the invention is installed on the coke oven carbonization chamber for regulating the pressure therein.

Description

technical field [0001] The invention discloses a coke oven carbonization chamber pressure regulating device, which belongs to the technical field of coke oven carbonization chamber pressure regulation. Background technique [0002] At present, the pressure in the coke oven carbonization chamber at home and abroad is mainly adjusted through the gas collecting pipe to adjust the entire furnace group. Due to the different coking states of the coke oven carbonization chambers, pressure fluctuations are likely to occur, which will bring adverse effects on coke oven production, such as During coal charging and at the initial stage of coking, the amount of raw gas introduced into the gas collection pipe is not enough, and sometimes even the gas collection pipe runs backwards, causing a large amount of raw gas to escape, seriously affecting the environment of the coke oven, or making the coal charging and dust removal system unable to operate normally; at the end of coal charging and...
