Description

Technical Field

[0001] The utility model relates to the technical field of liquid discharge devices, in particular to a coke oven gas liquid discharge device. Background Art

[0002] The 650-750℃ raw gas from the coke oven is cooled by spraying circulating ammonia water and cooling in the gas primary cooler to 21-23℃. Most of the water vapor, tar gas, naphthalene and solid particles contained in the gas are condensed and separated, and some ammonia, hydrogen sulfide, hydrogen cyanide, etc. in the gas are dissolved. Then the gas enters the electric tar precipitator to further remove the tar in the gas. After desulfurization or directly enters the gas blower for pressurization, it enters the ammonium sulfate process and other processes.

[0003] In normal production, due to the high temperature control of the primary cooler, the poor operation of the electric tar collector, and the unreasonable control of the desulfurization liquid-to-gas ratio, the coal gas is prone to high levels of tar, water vapor, naphthalene, desulfurization liquid and solid particles. Coke powder, coal powder, water vapor, desulfurization liquid, etc. are easily mixed and condensed together to increase the particle diameter. Especially after being pressurized by the gas blower, under the action of centrifugal force, large particles are thrown to the casing and pipe wall. If the direction of the gas flow changes, under the action of gravity, they are deposited at the bottom of the pipeline behind the machine, blocking the pipeline and increasing the resistance of the gas system. The corrosive substances such as hydrogen sulfide and hydrogen cyanide contained in it accelerate the corrosion of the gas pipeline and affect the safe and stable operation of the gas purification and recovery system.

[0004] At present, the coke oven gas drainage device is mainly based on gas water seal, which only discharges the liquid flowing at the bottom of the pipeline, and some large particles cannot be discharged, which still causes pipeline blockage. Generally, when the gas pipeline is blocked, steam purging and circulating ammonia water spraying and flushing are often used to clean it, which does not fundamentally solve the problem of gas pipeline blockage, wastes energy, and affects the water-gas balance and heat balance in the gas.

[0005] Therefore, a coke oven gas drainage device is proposed. Utility Model Content
