Zusammenfassung:An exhaust gas treatment apparatus according to an embodiment of the present invention is provided. The exhaust gas treatment apparatus according to an embodiment of the present invention comprises: an exhaust pipe which includes an inlet part into which exhaust gas containing soot generated from a combustion engine flows and an outlet part from which the exhaust gas is discharged; a stepped part which is formed inside the exhaust pipe between the inlet part and the outlet part and has an inner diameter decreasing stepwise; a blade part which is installed inside the exhaust pipe between the inlet part and the stepped part and rotates the exhaust gas to generate centrifugal force; a soot collection tank which collects soot contained in the exhaust gas due to the protrusion of at least a portion of the exhaust pipe between the blade part and the stepped part; and an injection nozzle which sprays at least one of ammonia, ammonia solution, and urea water inside the exhaust pipe between the inlet part and the outlet part. Thus, nitrogen oxides contained in the exhaust gas can be effectively removed in a selective catalytic reduction reactor. 본 발명의 일 실시예에 의해 배기가스 처리장치가 제공된다. 본 발명의 일 실시예에 따른 배기가스 처리장치는, 연소기관에서 발생한 수트(soot)를 포함하는 배기가스가 유입되는 입구부와 상기 배기가스가 배출되는 출구부를 포함하는 배기관과, 입구부와 출구부 사이의 배기관 내부에 형성되며,내경이 단차지게 감소하는 단차부와, 입구부와 단차부 사이의 배기관 내부에 설치되어 배기가스를 회전시켜 원심력을 발생시키는 날개부와, 날개부와 단차부 사이의 배기관 중 적어도 일부가 돌출 형성되어 배기가스 속에 포함된 수트를 포집하는 수트포집탱크, 및 입구부와 출구부 사이의 배기관 내부에 암모니아, 암모니아 수용액, 요소수 중 적어도 하나를 분사하는 분사노즐을 포함할 수 있다.
