静电旋风分离器的流场分析

Flow Field Analysis of an Electrostatic Cyclone Separator

分别测试了CLT型静电旋风分离器 (C—除尘器 ;L—离心 ;T—筒体 )内安装电晕极和不安装电晕极两种情况下的三维速度分布 ;并与XCY型静电旋风分离器 (X—旋风 ;C—长锥体 ;Y—烟气 )内安装电晕极和不安装电晕极两种情况下的三维速度分布的测试结果进行对比 ,分析了电晕极的安装对静电旋风分离器内三维速度分布的影响。指出 :如果合理地选用旋风分离器 ,并在特定的位置上安装电晕极 ,能使旋风分离器内的速度分布更有利于提高离心力的分离作用 ,同时降低静电旋风分离器内的阻力 ;

A three dimensional speed distribution was tested respectively for two versions of CLT type (C-dust remover, L-centrifuge, T-cylinder) of electrostatic cyclone-separator, i.e., with and without a corona electrode being installed. The above-cited distribution was compared with that of two versions of XCY type (X-cyclone, C-long cone, Y-flue gas) of electrostatic cyclone separator, i.e., with and without a corona electrode being installed. After an analysis of the effect of corona electrode installation on the three-dimensional speed distribution the authors made the following observations. With the rational selection of a cyclone separator and the installation of a corona electrode at a specified location the favorable speed distribution in the cyclone separator will be conducive to enhancing the separation function of a centrifugal force and lowering the resistance in the electrostatic cyclone separator. The authors also discussed how to achieve a rational configuration of the electrostatic cyclone separator.
