【摘要】 为了有效提高新型多效旋风分离器对粒径为0.1~3μm颗粒的分离效率,获取该设备的阻力性能,采用实验方法研究该新型多效旋风分离器压降与进口气速的关系,并与Lapple型旋风分离器进行比较。结果表明:进口风速为5~30m/s时,主体直径为0.25m的多效旋风分离器总阻力系数为7.29,其中,一级和二级预分离螺旋管的阻力系数分别为1.04和1.73;主体的阻力系数为4.52。直径为0.25m的Lapple型旋风分离器的阻力系数为7.21。更多还原

【Abstract】 In order to increse the collection efficiency for particle with size of 0.1 ～3 μm by the new type multi-effect cyclone separator and obtain its pressure drop performance, the total pressure drop for five types of cyclone separator was studied by experiments and was compared with Lapple cyclone. The results showed that within 5～30 m/s inlet velocity, the drag coefficient was 7.29 for the multi-effect cyclone separator with diameter of 0.25 m, 1.04 for the fist stage of helical pipe, 1.73 for the second stage, and 4.52 for the cylinder. The drag coefficient of Lapple cyclone with diameter of 0.25 m was 7.21.更多还原
