摘　　要：实验测定了常规旋风分离器内断面流量沿高度的分布 ,发现了在排气芯管入口断面附近有近 2 4%的短路流量并提出设法减少这部分短路流量是提高分离效率研究的一个方向 .通过对安装不同类型减阻杆后下降流量的测定比较 ,发现了非全长减阻杆下端固定时有增加减阻杆上方断面下降流量的功能 .这将延长含尘气流在分离器内的停留时间 。The distribution of flow rate on different heights of cyclone with and without Repds is presented. It is found that about 24 percent of total flow rate near the exit of normal cyclone is short circuited. Because the short Repds can increase the flow rate in different heights of cyclone, it is reasonable to consider that this kind of Repds can increase the separation efficiency of cyclone while reducing the pressure drop. \;
