Description
Technical field
The utility model relates to coke oven exhaust gas process field, is particularly related to a kind of coke oven chimney ammoniacal liquor dedusting EGR.
Background technology
In coke oven chimney discharging waste gas every day of coke-oven plant, containing approximately 1.35 tons, dust, because a large amount of diffussion of dusts is in air, cause atmosphere pollution; In coke-oven plant's technique, produce 250 tons of remained ammonias every day simultaneously.Prior art is that remained ammonia is back to quenching after sewage plant is processed, but waste water after treatment is high containing ammonia concentration, and the steam distributing when quenching causes certain influence to surrounding enviroment.
Utility model content
The technical problem that the utility model solves is to provide a kind of coke oven chimney ammoniacal liquor dedusting EGR, to solve the problem proposing in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of coke oven chimney ammoniacal liquor dedusting EGR, comprise clarifier-tank, the first sedimentation basin, deflector, enter mouth, chimney, shower nozzle, the second sedimentation basin, aqua ammonia pump, ammoniacal liquor pond, filter screen, upper spacer, lower clapboard, in described clarifier-tank, be provided with two lower clapboards whole clarifier-tank is divided into the first sedimentation basin, the second sedimentation basin and ammoniacal liquor pond, in described the second sedimentation basin, be provided with upper spacer, dividing plate between the second sedimentation basin and ammoniacal liquor pond is provided with filter screen, described the first sedimentation basin is provided with chimney, and be provided with deflector between the first sedimentation basin and chimney, described chimney is provided with into mouth, the top of entering mouth in chimney is provided with shower nozzle, described shower nozzle connects the aqua ammonia pump of top, ammoniacal liquor pond.
As preferably, described lower clapboard is semi-enclosed dividing plate, and the ammoniacal liquor of the first sedimentation basin can be overflowed in the second sedimentation basin.
As preferably, between described upper spacer and clarifier-tank 1 bottom, be provided with gap, the convenient ammoniacal liquor rapid precipitation from entering in the first sedimentation basin.
This device by arranging the shower nozzle that sprays ammoniacal liquor in chimney, to carry out from the coal gas that enters mouth cooling time, the dust of going out in coal gas, ammoniacal liquor with dust is entered in the first sedimentation basin and is precipitated by deflector, then entered second and precipitated the precipitation that is, with the filtration of filter screen, make to be cleaned and to enter ammoniacal liquor pond with the ammoniacal liquor of dust, the purification that the ammoniacal liquor in described ammoniacal liquor pond can circulate to flue gas by aqua ammonia pump.
Beneficial effect: of the present utility model simple in structure, easy to operate and effectively save the energy when purifying smoke, make ammoniacal liquor can repeat practicality.
