Abstract

배기가스 처리장치를 개시한다. 본 발명의 일실시예에 따른 배기가스 처리장치는 배기가스에 포함된 배출규제가스를 처리액에 접촉시켜 배출규제가스를 흡수제거하는 기액반응기; 상기 기액반응기에 상기 처리액을 공급하는 처리액 공급탱크; 및 상기 배출규제가스를 흡수한 처리액인 폐처리액을 배출규제가스를 흡수하지 않은 처리액으로 재생하고, 재생된 처리액을 상기 처리액 공급탱크에 공급하는 기액분리 처리액 재생유닛; 을 포함하고, 상기 기액분리 처리액 재생유닛은 기체는 통과하지만 액체는 통과하지 못하는 기액분리막을 포함하여 기액분리막은 폐처리액이 유동하는 액체유동로와 배출규제가스가 유동하는 기체유동로를 구획하고, 폐처리액에 흡수된 배출규제가스는 상기 액체유동로를 유동하면서 기액분리막을 통과하여 낮은 배출규제가스 분압이 형성된 기체유동로로 이동하여 배출규제가스와 처리액으로 분리할 수 있다.
