The effect of the two types vortex finder on the performance of the single and double inlet cyclone separators was experimentally investigated. In particular, the collection efficiency, pressure drop, and overall performance of single inlet cyclone separator with a cylindrical vortex finder, single inlet cyclone separator with an inverted-cone vortex finder, double inlet cyclone separator with a cylindrical vortex finder, and double inlet cyclone separator with an inverted-cone vortex finder were obtained and compared. The results show that the increasing diameter of the vortex finder would decrease the collection efficiency and pressure drop of the double inlet cyclone separators and increase the overall performance. It also found that inverted-cone vortex finder provides higher collection efficiency and pressure drop. Furthermore, when the vortex finder shape of the single inlet and double inlet cyclone separator changed, the variation of the collection efficiency and pressure drop was different, which is the same as changing the cyclone from a single inlet to double inlet.

实验研究了两种涡流探测器对单入口和双入口旋风分离器性能的影响。特别是，带有圆柱形涡流探测器的单入口旋风分离器，带有倒锥涡流探测器的单入口旋风分离器，带有圆柱形涡旋探测器的双入口旋风分离器和双入口旋风器的收集效率，压降和整体性能获得并比较了带有倒锥涡旋分离器的分离器。结果表明，增大旋涡分离器的直径将降低双入口旋风分离器的收集效率和压降，并提高整体性能。还发现倒锥形涡流探测器可提供更高的收集效率和压降。此外，
