摘　　要：分别概述了在石油、化工和矿场领域中,电场和磁场在非均相分离中的应用现状和进展。首先介绍了电脱水(液-液分离、固-液分离)、电除尘(气-固分离)等技术及其原理,分析了影响其分离性能的诸多因素。例如,对于电脱水,影响因素主要包括:电场是否为匀强电场、电场强度及电场方向等;对于电除尘包括:除尘颗粒的性质、除尘器内部流场等因素。磁场作用下的非均相分离目前研究热点集中在磁力旋流器上,介绍了磁力旋流器的结构类型和特点,总结了影响分离效果的诸多因素并对旋流器内部磁性颗粒的运动状况进行了对比分析。最后对电场和磁场在非均相分离中的应用技术进行了系统的论述;对促进分离效果的措施进行了总结和归纳;并展望了该项技术未来的发展趋势和研究热点。Application status and progress of applying both electric field and magnetic field in heterogeneous separation in the petrochemicals and mine areas were summarized. Firstly, both technologies and their working principle for electric dehydration （liquid-liquid separation, solid-liquid separation） and electrostatic precipitation （gas-solid separation） were introduced and the factors influencing their separation peiformance were analyzed, which including the uniformity of electric field, electric field＇ s intensity and direction in the electric dehydration and the properties of dust particles and dust collector＇ s internal flow field in the electrostatic precipitation. Under action of the magnetic field, the research hotspots of heterogeneous separation technology are mainly focused on the application of magnetic cyclone. Magnetic cyclone＇ s structure types and advantages were introduced in this paper and the factors influencing the separation effect were summarized and the movement of magnetic particles in hydrocyclone were compared and analyzed. Finally, applying electric field and magnetic field in heterogeneous separation was systematically discussed and this technology＇ s future trends and research hotspots were prospected, too.
