【Abstract】 This paper described the principle and four kinds of cleaning methods of a bag filter, analyzed the defects of traditional round bag filters. A new box bag filter that can clean itself automatically with high efficiency, and its experimental system were developed. The filtrating and regenerating efficiencies of the new box bag filter were investigated by the experimental system of a diesel engine. The results of the experiments indicate that the filtrating efficiency of the box filter is higher than 90%, and the design of the regenerating framework of the box filter is reasonable. In addition, the effects of pressure stabilizing and cooling of exhaust gas were also investigated, which proved that the design was feasible.更多还原
