Abstract: A new cyclone separator is designed. Compared with the base of model PV cyclone separator, the new cyclone separator adopts a new inlet structure with arc guide plate separating the intake, a diverged vortex finder, a lengthened cylinder and cone, and a new dust hopper structure with cone transition section, which match the appropriate size. To verify the separation performance of the new separator, a comparative experimental facility including the two kinds of cyclone separators is designed and established. The experiments measuring efficiencies and pressure drop are conducted at the inlet velocity of 14.4～26.1 m/s under a fixed dust concentration of 0.01 kg/m3. The results show that the new cyclone separator can reduce the pressure drop by 32.36% compared with the model PV cyclone separator, while the efficiency of both the separators are approximately equal.
Keywords: cyclone separator; structure optimization; diverged vortex finder; pressure drop; separation efficiency
