摘　　要：本文首次采用二维相多普勒粒子分析仪 (PDPA)对典型结构的百叶窗浓缩器内颗粒分布进行定量测量 ,得到了百叶窗浓缩器内平均粒径和测量点颗粒分布特点 ,从颗粒分布的角度探讨了百叶窗浓缩器气固分离机理 ,即浓缩机理。The measurements on gas solid two phase flow in the typical louver concentrator were conducted by using a two dimensional Phase Doppler Particle Analyzer (PDPA) system. Several kinds of mean particle diameters and particle composition profile at the measuring points were obtained. From the viewpoint of particle composition profile, the gas solid separation mechanism, namely concentration mechanism, was discussed.
