摘      要：Experimental and computational fluid dynamics was used in this study to predict the escape particles and evaluate the performance of PSC type cyclone tube with slotted vortex *** simulation results showed that the PSC type cyclone tube could remove the particles with a diameter greater than 5 μ*** PSC type cyclone tube increased the grade efficiency of particles with a diameter greater than 2 μm as compared with the Shell type cyclone *** circuit flow occurred around the vortex finder slots and there was almost no short circuit flow under the vortex finder *** small particles escaped from vortex finder slots of the PSC type cyclone *** slotted vortex finder could develop upwards flow near the vortex finder inlet outside wall and control the escape particles under the vortex finder *** force analysis of particles near the slotted vortex finder slots showed that gas flow carried the particles with a diameter smaller than 3 μm out the separator.
