本文的目的是研究二次流注射方法对旋风分离器中亚微米颗粒分离的影响。结果表明，颗粒收集效率随着旋流器上部柱段二次流量的增加而增加。为了获得较高的颗粒收集效率，二次流注射的位置应靠近上板，并应采用较高的注射速度。采用新开发的旋风分离器（a型），颗粒收集效率高。几乎所有的颗粒都被二次注入流体收集。三维模拟结果与实验数据定性一致。
The purpose of this paper is to study the effects of a secondary flow injection method on submicron particle separation in a cyclone. It is found that particle collection efficiency increased with an increased secondary flow rate in the upper cylindrical section of the cyclone.In order to achieve a high particle collection efficiency, the location of the secondary flow injection should be close to the upper plate and a high injection velocity should be used.The use of a newly developed cyclone (type A) resulted in a high particle collection efficiency. Nearly all particles are collected by the secondary injection fluid flow. Three-dimensional simulation results are qualitatively agreed with the experimental data.
