摘　　要：概述了国内外基于磁场来强化非均相介质分离的研究进展,对相关的强化方法进行了分析和对比。根据磁场作用的非均相介质类别介绍了不同领域磁场辅助多相介质分离技术、设备及工作原理,如磁选机、涡电流分选机、重介质磁力旋流器、磁盘分离器、磁场辅助分离气-固旋流器、磁流化床等。根据应用领域可简要概括为磁场辅助固体分离(具有不同导磁性的固体)、气-固分离、固-液分离、液-液分离等。总结了磁场分布、磁场与颗粒作用、磁场与流场耦合的模拟方法,为磁场强化多相介质分离提供依据。针对普通设备分离能力存在的瓶颈问题,文中提出应综合考虑磁场与设备操作参数等因素以最大限度提高分离效率,应加强磁场与流场耦合研究并将磁场强化分离领域扩大至非磁性流体。The research progress of magnetic field-based enhancement of heterogeneous media separation is reviewed, and the related enhancement methods are analyzed and compared. According to the types of heterogeneous media affected by magnetic field, the technology, equipment and working principle of magnetic field-assisted multiphase media separation in different fields are introduced,namely, magnetic separator, eddy-current separator, heavy medium magnetic cyclone, disk separator,magnetic field-assisted separation gas-solid cyclone, magnetic fluidized bed and so on. It can be summarized as magnetic field-assisted solid separation(solids with different magnetic conductivity), gassolid separation, solid-liquid separation, liquid-liquid separation, etc. The simulation methods of magnetic field distribution, interaction between magnetic field and particles, coupling of magnetic field and fluid field are summarized, which provides a basis for magnetic field enhancing multiphase media separation. Aiming at the bottleneck problem of common equipment separation ability, it is proposed that magnetic field and equipment operation parameters should be considered to maximize separation efficiency, the coupling between magnetic field and fluid field test should be strengthened and the field of magnetic field separation should be extended to non-magnetic fluid.
