For realizing above-mentioned utility model purpose, the utility model has adopted following technical scheme:
A kind of coke oven ammoniacal liquor system's tar slag pre-separation and removal system comprise:
Be used for the mixture of tar, ammoniacal liquor and tar slag is carried out the tar slag preseparator of initial gross separation;
Be used to accept institute's tar slag that obtains and residual tar after the initial gross separation, ammonia water mixture, and carry out the mechanical settling tank of Gravity Separation, be provided with in the said mechanical settling tank and be used for slag scraping mechanism that tar slag is scraped;
Be used to accept the tar slag case of the tar slag that scrapes in the mechanical settling tank;
The storage tank jar that is used for ccontaining tar/ammonia water mixture,
Said tar slag preseparator, mechanical settling tank and storage tank jar are communicated with through pipeline.
Further, said mechanical settling tank is connected with the tar slag case through the tar sealing device.
Said tar slag preseparator is more than two.
Said storage tank jar adopts underground emptying groove, is provided with submerged pump in the said underground emptying groove, and said submerged pump is communicated with the tar slag preseparator through pipeline.
A kind of coke oven ammoniacal liquor system's tar slag pre-separation and removal technology comprise the steps:
(1) mixture with tar, ammoniacal liquor and tar slag carries out initial gross separation through the tar slag preseparator;
(2) tar that initial gross separation is gone out/ammonia water mixture input next procedure is imported mechanical settling tank with the tar slag that initial gross separation goes out with residual tar, ammonia water mixture simultaneously;
(3) through mechanical settling tank tar slag and residual tar, ammonia water mixture are carried out Gravity Separation, the upper strata is tar/ammonia water mixture, and lower floor is a tar slag;
(4) step (3) tar/ammonia water mixture that obtains is entered the storage tank jar, subsequently with in the tar in the storage tank jar/ammonia water mixture input tar slag preseparator;
(5) step (3) tar slag that obtains is scraped in mechanical settling tank through slag scraping mechanism, and be transferred to coal blending in the tar slag adding set.
Further, the storage tank jar adopts underground emptying groove described in the step (4), and through the submerged pump that is provided with in the underground emptying groove tar/ammonia water mixture is imported in the tar slag preseparator.
Preferably, be at first tar slag to be scraped from mechanical defecator in the step (5), and change in the tar slag case, then again tar slag is transferred to coal blending in the tar slag adding set.
