A self-regulating raw gas device for coke oven with single carbonization chamber

Abstract

The present invention provides a self-regulating raw gas device for a coke oven with a single carbonization chamber, which includes a rising pipe, a bridge pipe, a gas collecting pipe, an integrated water seal valve, a first nozzle, and a second nozzle; one end of the bridge pipe is connected to a rising The other end of the integrated water seal valve is connected to the upper end of the integrated water seal valve along the vertical direction; the bottom of the integrated water seal valve is connected to the top of the air collecting pipe, and the piston rod inside the integrated water seal valve is fixed on the top at one end and fixed at the other end. Extending to the inside of the bridge tube, the integrated water seal valve includes a nozzle seat; the first nozzle is connected to one end of the bridge tube through threads, and the nozzle includes a base and a protrusion; the second nozzle is provided with multiple groups, fixed and installed symmetrically along the circumference On the nozzle seat on the surface of the integrated water seal valve. When the device is charging coal into the carbonization chamber, the gas collecting pipe can fully inhale the crude gas by using the negative pressure, thereby reducing the escape of the crude gas, achieving the effect of dust reduction and dust removal, and can also reduce equipment loss and production costs.

Description

technical field [0001] The invention belongs to the field of coke oven equipment, in particular to a self-regulating raw gas device for a coke oven with a single carbonization chamber. Background technique [0002] The coke oven gas collecting pipe is mainly used to collect the raw coal gas produced after coal combustion inside the coke oven. Its internal pressure value is a very important coking process parameter. decided. The stability of the gas collecting pipe pressure is directly related to the quality of coke cake products, and at the same time affects the air quality above the coke oven. Once the pressure in the single carbonization chamber of the coke oven is too high, smoke, waste gas and harmful gases will escape from the furnace door cover or the seal of the carbonization chamber, and this waste gas contains a large amount of harmful ingredients to the human body, which not only endangers the workers on the job healthy, while polluting the atmospheric environmen...

AI Technical Summary

Problems solved by technology

Once the pressure in the single carbonization chamber of the coke oven is too high, smoke, waste gas and harmful gases will escape from the furnace door cover or the seal of the carbonization chamber, and this waste gas contains a large amount of harmful ingredients to the human body, which not only endangers the workers on the job healthy, while polluting the atmospheric environment around the coke oven

At present, the pressure adjustment method of the coke oven gas collecting pipe is extensive, the effect is relatively poor, the gas recovery rate is very low, a large amount of harmful gas is discharged into the atmosphere, and the environment is seriously polluted

[0003] Some manufacturers or enterprises use coke oven water seal valves to improve the above problems, but the conventional coke oven water seal valves still have the following problems: (1) The water storage tank parts are easily damaged by the vibration of the fixing nut of the tie rod during the production process. Loose, and the loose displacement of the three tie rod nuts is different, resulting in imbalance and deflection

When the deflection reaches a certain angle, the middle part of the tie rod will rub against the right-angled side of the flange for a long time, and the thrust of the valve core and the control rod is mainly concentrated on the worn tie rod, causing the tie rod to break

(2) During the production process of the water storage tank parts, the surface finish and the strength of the thread root will be reduced to a certain extent after thread processing

However, when spraying ammonia water or high-speed water flow, the spraying environment is in the coke oven production process, and there are many objects such as smoke and dust, which may easily cause spray blockage, affect the production process, and reduce work efficiency
