Particulate Matter discharged from diesel engines is noxious for the human body and it's severe emission regulation is planned and executed. Diesel Particulated Filter (DPF) is widely studied as an effective method for removing PM in exhaust gas from the diesel engines. However, the DPF has an essential weak point which is not to be able to remove smaller size of PM than the mesh size of the filter. Then the water driven scrubber system which can remove ultra small size of PM (less than 1μm) is proposed. As the first step of this study, the removal capability of PM of jet scrubber system and venturi scrubber system is examined. As the second step, by cooling the exhaust gas before entering the scrubber, the removal capability of PM is drastically improved and long-time operation becomes possible without supplementation of the operating water.
