HEAVY TAR RECOVERING APPARATUS FOR PREVENTING HEAVY TAR FROM STICKING TO HEAVY TAR CONVEYOR BY FLOWING MIXTURE AFTER MIXING HEAVY TAR DISCHARGED FROM DECANTERS WITH BENZOL
PURPOSE: To provide an apparatus for preventing bulk heavy tar from sticking between the bottom of tar conveyor and chain, blocking generation of spark caused by strong friction between a vibro-mill and bulk heavy tar and preventing heavy tar from accumulating in heavy tar tank to efficiently recover heavy tar and improve operation efficiency. CONSTITUTION: The apparatus(100) for recovering heavy tar in coke manufacturing process comprises decanters(110,120,130,140) for separating heavy tar flown in along with ammonia liquor from coke oven; a heavy tar receiver(150) which is slantly installed to flow the mixture after mixing the heavy tar with benzol by receiving the heavy tar separated in the decanters, to a lower portion of which a separation plate is mounted adjacently to separate flowing heavy tar from bulk heavy tar, and in which downward pipes are branched off from the lower side of the separation plate to guide heavy tar passing through the separation plate; bulk heavy tar milling means connected to a lower portion of the heavy tar receiver to mill bulk heavy tar that could not pass through the separation plate; and a heavy tar tank(200) which contains heavy tar flown in through the downward pipes from the heavy tar receiver and heavy tar milled by the bulk heavy tar milling means and includes a benzol separating and discharging means for separating and discharging benzol contained in the heavy tar.
