The present invention relates to an exhaust reduction apparatus and method for a diesel engine, which remove pollutants (harmful materials or the like) included in an exhaust gas by passing the exhaust gas of an engine sequentially through a main pollutant collection duct, a middle pollutant collection duct and an exhaust gas discharge duct, while inducing the exhaust gas passing through an exhaust gas discharge unit to revolve to generate a centrifugal force and also inducing the exhaust gas to be dissolved in a catalyst solution, thereby maximizing pollutant reduction efficiency. In addition, the exhaust gas discharge unit is arranged to be inclined at 30-40° along an outer circumferential surface of each collection duct such that the exhaust gas discharged through the exhaust gas discharge unit generates the centrifugal force as the exhaust gas revolves and at this time collides against an inner wall of each collection duct to separate particulate materials, thereby further enhancing exhaust gas filtering effect.

    본 발명은 디젤엔진용 매연 저감장치 및 저감방법에 관한 것으로, 엔진의 배기가스가 메인 매연 포집 덕트, 미들 매연 포집 덕트, 배기가스 배출 덕트를 순차적으로 거치면서 배기가스에 포함된 매연(유해물질 등)을 제거하도록 하되, 배기가스 배출 부를 통과하는 배기가스가 선회(旋回)하면서 원심력을 발생하도록 함과 아울러, 촉매용액에 용해되도록 유도함으로써, 매연 저감 효율을 극대화할 수 있으며, 각 포집 덕트의 외주 면을 따라 배기가스 배출 부의 배치가 30°∼40°로 경사지게 형성되어서, 배기가스 배출 부를 통해서 배출되는 배기가스가 선회하면서 원심력을 발생하며, 이때 각 포집 덕트의 내벽에 충돌하여서 입자상 물질이 분리되어 배기가스 여과효과를 더욱 높일 수 있다.
