摘要：
The characteristics of an axial flow cyclone separator were studied. The effects of blade space, rotating angle and dust exhaust gap on the pressure drop and tangential velocity of the cyclone separator at 2.5~6 m/s inlet air velocity were analyzed. The results showed that the pressure drop of the cyclone separator increases with the increase of inlet air velocity. The rotating angle of blades has little effect on the pressure drop of the cyclone, while the maximum tangential velocity increases with the increase of the rotating angle. The pressure drop and tangential velocity are greatly influenced by the change of blade space, and the pressure drop increases 31.1% when the blade space changes from 16 mm to 12 mm at 6 m/s inlet air velocity, while the tangential velocity increases 11%. Larger dust exhaust gap can significantly increase the pressure drop, and has little effect on tangential velocity. The efficiency of the cyclone separator with 16 mm blade space, blade rotating angle of 90 degrees and dust exhaust gap of 7.15 mm for A4 coarse dust can reach more than 85%. The results provide a basis for designing geometric parameters of axial flow cyclone separator. © 2019, Editorial Department of Journal of Northeastern University. All right reserved.
