摘　　要：为改善普通旋风器的分离效率,提出一种内置滤袋旋风器。通过对该模型不同滤袋尺寸下内部气固两相流场的模拟,观察其不同截面处的速度和压力云图得出:当滤袋直径与旋风器排气口直径相同且开始逐渐增大,设备的性能趋好;直到滤袋侧面与旋风器进气口内侧壁在俯视图投影中即将相切时,旋风器性能最为稳定;滤袋长度到达旋风器锥体时设备表现更稳定。To improve the separation efficiency of ordinary cyclones,a cyclone with a built-in filter bag is proposed.when the diameters of both filter bag and cyclone exhaust port are the same and enlarging gradually,the performance of the equipment tends to improve.When the side of the filter bag and the inner wall of the cyclone inlet are about to be tangent in the top view projection,the cyclone performance is very stable,and even more stable when the length of the filter bag reaches the cone of the cyclone.
