【Abstract】 The primarily designed high speed rotary self cleaning air filter adopted axial outlet and tangential inlet, the filtering efficiency of the filter was relative low and couldn’t reach the lowest efficiency limit. In order to enhance the filtering efficiency, the inlet and outlet structure of this new style of air filter were improved and the experimental research was carried out. The results showed that the filtering efficiency of the filter exceeded the lowest limit, this new style air filter can be practically developed further.更多还原
