본 발명은 코크스 냉각용 안수의 타르 분리 및 제거장치에 관한 것으로, 보다 상세하게는 코크스 생산시 코크스로 상승관 냉각용으로 살수되는 안수액중에 타르, 가스, 미분탄회분, 슬러지 등이 함께 혼합되어 순환되므로 이를 분리, 제거시켜 상승관 살수노즐 폐쇄를 방지할 수 있도록 한 코크스 냉각용 안수의 타르 분리 및 제거장치에 관한 것이다.The present invention relates to an apparatus for separating and removing tar from coking water for cooling, and more specifically, tar, gas, pulverized coal ash, sludge, etc., are mixed together in an ordination liquid that is sprinkled for cooling a coke oven riser during coke production. Therefore, the present invention relates to a tar separation and removal apparatus for coke cooling ordination, which separates and removes the coke cooling water so as to prevent the closing of the riser spray nozzle.

도 1은 종래의 코크스로 상승관 안수 순환 공정도로서, 일반적으로 코크스 생산시 코크스로(10) 상승관(11)은 안수(Ammonia Water)가 살수되어 냉각된다.1 is a conventional coke oven rising pipe ordination circulation process, the coke oven (10) during the coke production, the riser 11 is sprinkled with water (Ammonia Water) is cooled.

냉각시 발생되는 가스에는 타르 및 미분탄회분, 슬러지 성분이 집진되어 살수시킨 안수와 함께 다운컴마(down commer)로 이송되어 1차로 가스와 액체가 분리된다.Tar, pulverized coal ash, and sludge components are collected in cooling, and are transported to a down commer together with the sprinkled water, which separates the gas and the liquid.

2차로 플러싱 리커 데칸타(flushing liquor decanter)(12)에서 1차로 분리된 액체를 비중차를 이용하여 안수, 타르, 슬러지로 분리시켜 가장 가벼운 안수를 오버플로 시켜 안수탱크(14)에 저장시킨다.Secondly, the liquid separated first from the flushing liquor decanter 12 is separated into ordination, tar, and sludge using specific gravity difference, and the lightest ordination is overflowed and stored in the ordination tank 14.

이후, 상기 안수탱크(14)에 집수된 안수를 안수순환펌프(15)에 의해 재순환하여 상승관(11) 냉각 살수용으로 연속 사용한다.Thereafter, the ordination collected in the ordination tank 14 is recycled by the ordination circulation pump 15 to be continuously used for the cooling pipe of the riser 11.

그러나 코크스로(10) 상승관(11)에 부설된 살수노즐(미도시)이 타르나 미분탄회분에 의해 폐쇄되어 살수유량이 감소하게 되고 이에 의하여 상승관(11)의 온도가 급격하게 상승하게 된다.However, the sprinkling nozzle (not shown) installed in the coke oven 10 ascending pipe 11 is closed by tar or pulverized coal ash, so that the flow rate of the sprinkling water is reduced, thereby rapidly increasing the temperature of the rising pipe 11. .

상기와 같은 원인으로 인하여 종래에는 온도 상승을 예방하기 위한 대안으로 살수노즐 폐쇄시 상기 코크스로(10) 상승관(11)에 담수(16)를 살수시켜 냉각시킨 다.Due to the above causes, in the prior art, the fresh water 16 is sprinkled and cooled in the coke oven 10 and the rising pipe 11 when the spray nozzle is closed as an alternative for preventing the temperature rise.

그러나 상기의 공정에 의해 코크스로(10) 상승관(11)의 온도는 하강되지만 상기 담수(16) 살수에 따른 안수 발생량이 증가하게 되며 이 잉여 안수 증가에 따라 처리하는 증류비와 폐수 발생량이 증가하는 등, 부가적인 문제점이 발생되었다.However, although the temperature of the coke oven (10) rising pipe (11) is lowered by the above process, the amount of ordination is increased according to the fresh water (16) sprinkling, and the distillation ratio and the amount of wastewater generated by the increase of the surplus ordination are increased. Additional problems have arisen.
