摘　　要：概述了国内外基于电场-旋流耦合场来强化非均多相分离的研究进展,并对相应强化分离方法进行分析与归纳。根据不同介质类别分别介绍了电场-旋流耦合强化液-液分离、气-固分离、气-液分离、固-液分离等多相介质分离技术、设备及工作原理,例如:动态/静态静电旋流脱水装置、静电旋风除尘器/摩擦旋风分离器、静电旋风除雾器及电动旋液分离器。总结了电场类型与分布、耦合场与液滴、颗粒作用、耦合场数值模拟方法等,为研究电场-旋流耦合强化分离多相介质提供依据。针对特殊多相介质(如黏度大、密度差小及弱/无电导率等)分离性能较差的问题,本文提出应综合考虑耦合设备的结构尺寸、操作参数及安装条件,在提高分离效率的基础上,应加强电场-旋流耦合装置运行安全性的研究以扩大耦合强化多相介质分离的适用范围。The research progress of strengthening non-homogeneous multiphase separation based on electrostatic-cyclonic coupling field at home and abroad was outlined,and the corresponding strengthening separation methods were analyzed and summarized.The multi-phase media separation technologies,equipment and working principles such as electrostatic-cyclone coupling enhanced liquidliquid separation,gas-solid separation,gas-liquid separation and solid-liquid separation were introduced according to different media categories,for example:dynamic/static electrostatic cyclone dewatering device,electrostatic cyclone dust collector/friction cyclone separators,electrostatic cyclone mist eliminator and electric cyclone liquid separators.The electric field type and distribution,coupling field with droplet and particle action,as well as numerical simulation method of coupling field were summarized to provide a basis for the study of electrostatic-cyclone coupling to strengthen the separation of multiphase media.In view of the poor separation performance of special multiphase media(such as large viscosity,small density difference and weak/no conductivity,etc.),this paper proposed that the structural dimensions,operating parameters and installation conditions of the coupling equipment should be considered comprehensively,and on the basis of improving the separation efficiency,the research on the operational safety of the electric field-cyclone coupling device should be strengthened to expand the applicable scope for coupling to strengthen the multiphase media separation.
