摘要：为深入研究导叶式旋风管的分离机理,用不同粒度分布的SiO₂颗粒对分离总效率与粒级效率进行了对比研究。实验结果表明:入口颗粒的粒度分布不但对旋风管的分离总效率有影响,而且对粒级效率也有较大影响;不同粒径大小的颗粒在旋风管中的分离机理不同。

Abstract: In order to improve the separation mechanism of guide vane cyclone tube, the effect of particle size distribution of the SiO₂ particles on the separation efficiency and grade efficiency was investigated. The experimental results indicated that particle sizes had an effect on separation efficiency of cyclone tube, and also made a difference to grade efficiency. The particle's separation mechanism of different sizes in cyclone tube was different. 

Keywords: cyclone tube; particle size distribution; separation efficiency
