Coke oven chamber pressure regulation device

Abstract

The invention discloses a coke oven chamber pressure regulation device and belongs to the field of coal coking equipment. The coke oven chamber pressure regulation device comprises an ascension pipe,a bridge pipe and a gas collecting tube, wherein the ascension pipe is connected with the bridge pipe; a pneumatic actuating tube is hinged onto the gas collecting tube; one end of the pneumatic actuating tube is hinged onto the gas collecting tube, and the other end of the pneumatic actuating tube is hinged to a turning plate axis; a turning plate is fixedly connected onto the turning plate axis;the pneumatic actuating tube is connected with a control device through a wire. According to the coke oven chamber pressure regulation device disclosed by the invention, with the adoption of a singlecoking chamber pressure regulation system, a stable pressure of a single coking chamber can be realized, lots of raw coke oven gas can be guided into the gas collecting tube during coaling so as to prevent smoke dust from overflowing. The phenomenon that the raw coke oven gas in the gas collecting tube flows backwards into the coke oven chamber in the tail coking period can be avoided, the problem that a negative pressure exists at the bottom of the coke oven chamber in the tail coking period can be solved, and coke oven operation production and steady operation can be facilitated.

Description

technical field [0001] The invention relates to the field of coal coking equipment, in particular, the invention relates to a pressure regulating device for a coke oven carbonization chamber. Background technique [0002] The coke oven used in the coking plant is a JN60 55-hole coke oven. It turns out that the pressure in the carbonization chamber of the coke oven is mainly adjusted through the gas collecting pipe for the entire furnace group. Due to the different coking states of the various coking chambers of the coke oven, pressure fluctuations are likely to occur, which will bring adverse effects on the production of the coke oven. For example, when charging coal, the amount of raw gas introduced into the gas collection pipe is not enough, so that a large amount of raw gas escapes, which seriously affects the environment. , or make the coal charging and dust removal system unable to operate normally; at the end of coking in the coke oven, the raw gas generated in the ca...

Problems solved by technology

Due to the different coking states of the various coking chambers of the coke oven, pressure fluctuations are likely to occur, which will bring adverse effects on the production of the coke oven. For example, when charging coal, the amount of raw gas introduced into the gas collection pipe is not enough, so that a large amount of raw gas escapes, which seriously affects the environment. , or make the coal charging and dust removal system unable to operate normally; at the end of coking in the coke oven, the raw gas generated in the carbonization chamber decreases, and sometimes even causes the raw gas in the gas collection pipe to flow back into the carbonization chamber and decompose; and in the final stage of coking in the coking chamber Negative pressure appears at the bottom of the chamber, resulting in leakage in the furnace wall of the carbonization chamber and adverse effects on the coke oven, etc.
