Abstract
본 발명은 배기가스 탈질시스템에 관한 것으로, 보다 상세하게는 요소수가 배기가스와 혼합되어 암모니아로 변환되는 화학반응이 일어나는 반응챔버와, 상기 반응챔버에서 유입된 혼합가스에 포함되어 있는 질소산화물이 촉매와의 탈질반응을 통해 질소로 변환되는 화학반응이 일어나는 반응기를 포함하는 배기가스 탈질시스템에 있어서, 상기 반응챔버는 환원제와 배기가스가 짧은 시간 내에 혼합될 수 있도록 하는 다중혼합기를 포함하고, 상기 반응기는 촉매가 코팅되어 있으며 혼합가스가 통과할 수 있는 복수의 관통공의 측면격판이 물결모양형태로 형성되어 있는 촉매필터부를 포함하여, 환원제와 배기가스가 보다 짧은 시간 내에 혼합될 수 있도록 하여 반응챔버의 길이를 줄일 수 있고, 혼합가스와 촉매의 접촉면적은 유지하면서 관통공의 공간을 크게 확보할 수 있어 차압은 최소화하면서도 소음감쇄효과는 높일 수 있는 환원제혼합 및 소음감쇄 구조를 갖는 배기가스 탈질시스템에 관한 것이다.
