Embodiment Construction
[0012] Three air guide pipes 7 are provided in the dedusting water tank 8 . The lower duct 18, the sedimentation tank 19, and the clear water tank 20 are all buried in the ground with a brick-concrete structure, also known as a dark ditch, placed under the open space between the two guide rails of the coke pusher, with low cost and space saving. The bottom of the lower draft pipe 18 is inclined, which is convenient for the sediment in the circulating water to be discharged downward. Circulating water 22 is arranged in the lower air duct 18, and the circulating water 22 can not occupy the space in the lower air duct 18, and the upper space reserved in the lower air duct 18 is used as the air duct 23. An air inlet 30 is arranged above the lower air duct 18 , the air duct 23 communicates with the upper air duct 11 through the air inlet 30 , and the end is connected with the induced fan 25 . A rotary damper 29 is provided above the air inlet 30, and a telescopic sleeve 31 is prov...

A coke oven wet method dedusting station aims to realize small occupied area, small operation energy consumption and high dedusting efficiency. The dedusting station comprises a dedusting water tank, an induced draft tube, a sedimentation tank, a clear water pond, a water pump, a ditch and a draught fan, wherein the dedusting water tank is internally provided with an inclined-arranged air duct, awater curtain sprayer is arranged in the inclined section of the air duct, the dedusting water tank is arranged on a track which is arranged at the top part of the coke oven body, the induced draughttube comprises an upper induced draft tube and a lower induced draft tube, the upper induced draft tube is communicated with the air duct in the dedusting water tank, the lower induced draft tube is arranged underground and is arranged between two tracks of a coke pusher, the lower induced draft tube is provided with an air intake the position of which corresponds to the position of a furnace door, a rotary air door is arranged above the air intake, the lower end of the upper induced draft tube is provided with a flexible jacket, the lower part of the flexible jacket is in abutment joint withthe air intake on the lower induced draft tube, the sedimentation tank and the clear water pond are arranged underground, the front of the sedimentation tank is communicated with the lower induced draft tube, and the back thereof is communicated with the clear water pond via a communicated hole, and the clear water pond is communicated with the ditch.
Description
technical field [0001] The invention relates to a coke oven wet dust removal station. Background technique [0002] During the dry distillation process of the coking oven, a large amount of carbon monoxide, carbon dioxide, sulfur dioxide, nitrogen dioxide, tea, benzene, coal tar and other organic substances are cracked and discharged. At the same time, a large amount of combustible particles and ash are emitted in the form of soot. This part of soot is mainly produced when the coal cake is charged into the furnace and coke is discharged, and of course it also contains the above-mentioned various components. The current coke oven has two sets of discharge systems, one is that the gas generated when the furnace is closed and dry distillation coking is drawn out through the pipeline, and after cooling with ammonia water, sulfur dioxide, tar, etc. are treated separately through desulfurization towers and other equipment, and carbon monoxide gas is led back into the furnace to su...
