Embodiment Construction

[0026] The present invention will be described in further detail below in conjunction with accompanying drawing description and embodiment:

[0027] A method for automatically adjusting the pressure of a coke oven carbonization chamber. The method controls the flow of raw gas by controlling the opening of the water seal valve disc to change the size of the passage section of the raw gas in the water seal valve device of the bridge tube, thereby achieving control of coke. The purpose of furnace carbonization chamber pressure.

[0028] See figure 1 , figure 2 , image 3 , coke oven carbonization chamber pressure automatic adjustment device, including rising pipe 1, bridge pipe valve body 2, bridge pipe water sealing valve device 3, gas collecting pipe 4, computer control system 5, pressure control device 6, pressure measuring device 7, rising pipe 1 is located at the upper part of the coke oven carbonization chamber, the upper part of the rising pipe 1 is connected to the br...

Abstract

The invention relates to an automatic pressure regulating method and a device for a coke oven chamber, which is characterized in that the lower end of a cylinder of a bridge pipe water sealing valve device is an inclined surface, the inclined surface is formed by inclining downwards towards the nearest (farthest) end from the farthest (nearest) end of a water sealing valve disc shaft of the bridge pipe water sealing valve device in a mode of oblique lines with same slope or broken lines and curve contours with different slopes, rotation of the water sealing valve disc shaft enables one end of the water sealing valve disc shaft closing to the inclined surface to firstly sink into a water sealing valve disc, a gas channel is formed between the upper end of the inclined surface and the water sealing valve disc, and size of gas flow is controlled by the opening size of the water sealing valve disc. The device is used for controlling the pressure of single coke oven chamber, realizes no overflow of soot when coals are charged in a coke oven and in coking period, avoids negative pressure occurring in the coking chamber in coking terminal, and prevents air from leaking into the coking chamber to burn coke and damage the oven body; the equipment has simple structure, low manufacture cost and low operation and maintenance requirement, and is easy to manufacture.

Description

technical field [0001] The invention relates to a coke oven, in particular to an automatic adjustment device for the pressure of a carbonization chamber used in a top-charging coke oven or a tamping coke oven. 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; , the raw gas produced...
