摘要

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42mm、直径为18mm，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

Abstract:In order to study the separationperformance and influencing factors of cyclone separator involved in theatmospheric monitoring system

the structure size of the particle was designedand the threedimensional physical model of the flow field was established bythe design criterion of the cyclone separator. Reynolds stress model (RSM) wasused to simulate gas velocity field

then the particles phase was added and thegassolid twophase flow was calculated by the discrete phase model. Theeffect of internal and external vortices on particle motion and the separationof particles is obtained. In order to satisfy the requirements of separation performance

the parameters such as the length and diameter of exhaust pipe were changedsuccessively and the geometric standard deviation of the efficiency curve ofseparation was calculated and compared on the basis of the initial structurescheme. Theresult show that the optimal exhaust pipe length is 42mm and diameter is 18mm. It caneffectively inhibit the generation of short circuit flow

increase the externalvortex area

guarantee the geometric standard deviation is 1.5±0.1

improve the separation efficiency.
