基于PV型旋风分离器的结构优化实验

Experimental study on structural optimization of cyclone separator based on PV type

设计了一种新型旋风分离器。相对于PV型旋风分离器,新型旋风分离器采用弧形导流板分隔进气的入口结构、分流型排气的出口结构、加长型的筒体和锥体的结构,有锥顶过渡段的灰斗结构,并匹配了合理的尺寸。为了验证新型分离器的性能,设计并搭建新型结构和基准PV型旋风分离器的冷模对比实验装置,在入口气速为14.4-26.1m/s、入口含尘质量浓度为0.01kg/m^3时,同时测量2种分离器的效率和压降。对比实验结果表明:相对于基准PV型分离器,新型旋风分离器能够减小压降约32.36%,同时保证新型分离器的效率与基准效率相当。

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/m^3. 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.
