摘要:为了研究大气监测系统中涉及的旋风分离器的分离性能及影响因素,根据旋风分离器设计准则,设计了结构尺寸,建立流场三维物理模型,应用雷诺应力模型(RSM)模拟气相速度场,然后加入颗粒相应用离散相模型进行气固两相流耦合计算,得出内外旋涡形式的流场对颗粒运动影响及颗粒的分离情况;为满足分离性能的要求,在初始结构方案基础上,依次改变排气管长度、直径等参数,计算并比较分离效率曲线的几何标准差。结果表明:较优结构排气管长度为42mm、直径为18mm,可有效抑制短路流产生,增大外部漩涡区域,保证了几何标准差为15±01,提升了分离效率。

Abstract:In order to study the separation performance and influencing factors of cyclone separator involved in the atmospheric monitoring system, the structure size of the particle was designed and the threedimensional physical model of the flow field was established by the design criterion of the cyclone separator Reynolds stress model (RSM) was used to simulate gas velocity field, then the particles phase was added and the gassolid twophase flow was calculated by the discrete phase model The effect of internal and external vortices on particle motion and the separation of particles is obtained In order to satisfy the requirements of separation performance, the parameters such as the length and diameter of exhaust pipe were changed successively and the geometric standard deviation of the efficiency curve of separation was calculated and compared on the basis of the initial structure scheme The result show that the optimal exhaust pipe length is 42mm and diameter is 18mm It can effectively inhibit the generation of short circuit flow, increase the external vortex area, guarantee the geometric standard deviation is 15±01, improve the separation efficiency
