Optimized Design of a Separator for Dust Loading Test of High Efficiency Particulate Air Filters

为了使旋风分离器分离出来的颗粒大小适用于高效过滤器容尘性能试验,采用试验设计(Design of Experiment,DOE)法,并借助计算流体力学(Computational Fluid Dynamics,CFD)软件优化旋风分离器的结构尺寸,显著提升了分离性能,使切割粒径从微米级减小至亚微米级。同时,分析了各结构尺寸对分离效率的显著影响及交互作用。

In order to make the particle size separated from the cyclone suitable for the dust holding performance test of HEPA filter,the Design of Experiment(DOE)method is adopted,and the Computational Fluid Dynamics(CFD)is adopted.The CFD software optimizes the structural size of the cyclone separator,significantly improving the separation performance and reducing the cutting size from micron to sub-micron.At the same time,the significant influence and interaction of each structure size on the separation efficiency were analyzed.
