     종래에는 대형 정유 탱크의 경우, 대규모로 발생하는 슬러지를 처리하기 위하여 정기적으로 청소작업을 실시하는데, 정유탱크 내부에 작업인부가 들어가서 작업대를 설치한 후 슬러지를 수작업으로 포대에 담아 크레인을 이용하여 탱크 밖으로 배출하였다. 
     종래의 이같은 슬러지의 처리 방법은 대부분의 공정을 수작업으로 수행하기 때문에 작업에 많은 시간이 소요되었고, 이에따른 인건비로 인해 처리비용이 많이 들었다.    뿐만 아니라, 슬러지의 처리장은 기름과 유독가스 등 위험물질이 상존하기 때문에 작업효율이 떨어지고 위험도 컸다.    또한 슬러지를 옮겨온 후에도 폐기물을 다시 안전하게 처리하는 후처리 작업을 해야하는 번거러움이 있었다. 
     따라서, 본 발명은 이동 가능한 고성능 진공펌프카에 어큐물레이터와 에어 콤프레사가 설치된 진공장치를 통하여 흡입공기를 만들어 자동적으로 정유탱크의 슬러지를 흡입한 후 블로워와 유수분리기와 원심분리기를 거치면서 슬러지를 자동적으로 처리할 수 있도록 한 장치에 관한 것이다.    보다 구체적으로는, 슬러지를 흡입하기 위하여 투입했던 투입공기를 고속 송풍기(Blower)에서 분리한 후, 유수분리기에서 압출롤러를 사용하여 유분과 슬러지를 분리하고, 원심분리기에서 탈수한 후 슬러지의 부피를 대폭줄인 케이크 상태로 만들어 슬러지를 포대나 드럼통에 담아서 처리하므로써 자동적으로 슬러지를 처리할 수 있다.
