摘要： 为了系统评价天然气净化用多管旋风分离器的分离性能，在线测量了入口气速6~24 m/s、入口颗粒浓度30~2000 mg/m3范围内多管旋风分离器的分离效率和分级效率. 结果表明，多管旋风分离器的分离效率和分级效率都随入口气速和入口颗粒浓度增大而提高. 与单管旋风分离器相比，在相同实验条件下，多管旋风分离器的分离效率下降2%~15%；单管旋风分离器基本能除净粒径大于10 mm的颗粒，而多管旋风分离器只能去除15 mm以上的颗粒. 多管旋风分离器的压降主要是内部单管旋风分离器的压降，占整个压降的80%~90%.

Abstract: In order to evaluate the separation performance of multi-cyclone separator for purification of natural gas, the overall collection and grading efficiencies of a multi-cyclone separator with inlet velocities of 6~24 m/s and particle concentrations of 30~2000 mg/m3 were investigated under atmospheric pressure and room temperature. The particle concentration and particle size distributions of inlet and outlet of the cyclone separator were measured by aerosol spectrometer based on measured particle number. The experimental results showed that the overall collection efficiency and grade efficiency increased with increasing of particle concentrations and inlet velocities. The overall collection efficiency of multi-cyclone separator was 2%~15% less than that of single cyclone separator at the same operation condition. Most of the particles with the diameters bigger than 15 mm could be removed by multi-cyclone separator while single cyclone separator could remove clearly the particles bigger than 10 mm. The pressure drop of the single cyclone separators in a multi-cyclone occupied 80%~90% of the overall pressure drop of multi-cyclone separator.
