【摘要】 采用五孔探针测试技术及相应的计算机数据采集与处理系统，测定了旋转直流内循环式旋风分离器的三维流场分布。对所测流场分4个区域进行了分析讨论，并对内循环气量进行了衡算。结果表明该新型旋风分离器设计合理，结构有利于气流中颗粒的分离。更多还原

【Abstract】 By employing the five-hole exploring needle technique and its computer systemfor data collecting and processing, the flow field of rotary uniflow & inner-recycle cyclone separator was experimentally studied in this paper. The measured flow field was respectively discussdand analyzed in four different regions, and flow rate mass balance of the inner-recycled gasstream was conducted.The result reveals that the design of the new type of cyclone separator ispracticable and its structure is good for the separation of particles from gas stream.更多还原
