Abstract

본 발명은 습식배연탈황장치에 관한 것으로서, 간단한 구성이면서도 각별히 낮은 출구미스트농도를 실현할 수 있고, 또한 보수가 용이한 습식배연탈황장치를 제공하는 것을 목적으로 한 것이며, 그 구성에 있어서, 바닥부의 탱크에 흡수제슬러리가 공급되는 흡수탑과, 상기 탱크내의 슬러리를 흡수탑상부의 배연도입부에 보내서 배연과 접촉시키기 위한 순환펌프를 구비하고, 상기 배연도입부로부터 도입한 배연속의 아황상가스를 상기 흡수제슬러리에 의해 흡수제거하고, 상기 탱크끝부분의 상부면쪽으로부터 위로 올라가도록 형성한 배기덕트로부터, 아황산가스가 제거된 처리후 배연을 도출하는 습식배연탈황장치에 있어서, 상기 배기덕트에 있어서의 위로 올라간부분을 세로 칸막도록 미스트분리기를 배설하고, 이 미스트분리기의 하단부를 탱크내의 흡수제슬러리액면내에 연장하여 이루어지는 것을 특징으로 한 것이다.
