Purification water through soul water stripper the most directly enters sewage treatment plant, but is delivered to acidity of the present utility model
Steam carries the coke cooling water oil removing pot 40 of after-purification water pre-treatment means to carry out settling oil removing remove impurity, makes as coke cooling water when cold Jiao
With, absorption and the high-temperature evaporation at cold burnt process initial stage by microporosity petroleum coke make stripping after-purification water be purified.This
The operation principle of the sewage stripping after-purification water pre-treatment means of utility model is as follows:
Stripping after-purification water is delivered to coke cooling water water tank 20, and (branched pipe 14 that also can first pass through on water inlet pipe 11 is introduced into
Coke cooling water oil removing pot 40), when normally producing, stripping after-purification water is delivered in coke cooling water water tank 20 by water inlet pipe 11,
In the cold burnt process medium and small feedwater stage, start coke cooling water pump 21, purification water be delivered to coke drum 30, feed water the most on a small quantity into
Entering bottom coke drum 30, the coke with in coke drum 30 about 300 DEG C contacts and is vaporized, and vapour phase enters contact by soda pop pipe 13
Cooling tower 80, coke drum 30 pressure on top surface starts gradually to rise, and along with the reduction of temperature, the most slowly drops to 0.006-
0.007MPa (gauge pressure), now gives to coke drum 30 water-cooled burnt in a large number, when coke drum 30 pushes up pressure-fired, closes to contact cooling
First valve of tower 80, is opened into the second valve of coke cooling water oil removing pot 40, by from stream mode to one-level coke cooling water settling tank
51 and two grades of coke cooling water settling tanks 52, turn water pump 61 with cold Jiao and extract out from two grades of coke cooling water settling tanks 52, through filter 60 He
Air cooler 70 will divide two-way after being water-cooled to 50-60 DEG C, a road is entered coke cooling water water tank 20, so recycled, additionally
One tunnel decontaminated water treatment plant.In the decoking stage, start coke cutting water elevator pump and deliver to high-order water pot, be used for cutting burnt supplementary water, flow into
Filtration Adsorption is carried out in storing burnt pond.
The many micropores of coke in coke drum 30 of the present utility model, include abundant functional group, are carbon back absorption well
Agent, can highly desirable transfer in coke by the COD, sulfide, phenols and the ammonia nitrogen absorption that purify in water, purify COD in water
Can remove 50-60%, ammonia nitrogen removal more than 90%, sulfide removes more than 80%, and can also be to biochemical sewage process bacterium
Plant harmful aldehydes matter substantially to remove, be substantially reduced the load of sewage treatment plant.Purifying COD in water is Organic substance, by inhaling
Attached transferring to obtains resource recycling, saving water resource simultaneously in coke.
Purification water after sewage stripping is changed to strip after-purification water pre-treatment means and carries out high temperature vapour by this utility model
Mentioning that coke adsorbs, the COD, sulfide and the ammonia nitrogen that purify in water are greatly reduced.Owing to stripping after-purification water water quality is poor, unsuitable
Be directly entered sewage treatment plant, be passed to strip after-purification water pre-treatment means for delay coking device coke cooling water, then
Drain into sewage treatment plant again, achieve good effect.Sewage stripping after-purification water pre-treatment means of the present utility model can
Part removes COD, sulfide, ammonia nitrogen and aldehydes matter in stripping after-purification water, reduces sewage disposal difficulty, both can save water money
Source, can avoid again the high purified water containing COD, sulfide, ammonia nitrogen and aldehydes matter to run in sewage treatment plant, significantly alleviate dirt
Water processes load, it is ensured that outside sewage treatment plant, draining is qualified.
The above is preferred implementation of the present utility model, certainly can not with this limit this utility model it
Interest field, it is noted that for those skilled in the art, before without departing from this utility model principle
Putting, it is also possible to make some improvement and variation, these improve and variation is also considered as protection domain of the present utility model.
