电磁协同油水分离是一种有前途的技术，用于深度脱水，效率更高，脱水周期较短和对场参数的灵活控制。在本文中，没有胶体和沥青烯的非导电硅油被用作连续相。可以排除磁化强度和洛伦兹力对连续相的影响，以探索电场和磁场协同脱水的机理。首先，表征了液滴的粒径。结果表明，分散相分布均匀，平均粒径为18.24 um。然后比较了不同类型的外场的脱水性能。实验结果表明，AC电场与磁场的脱水性能优于单个AC电场的脱水性能。交流电场和磁场的脱水性能优于直流电场和磁场的脱水性能。在此基础上，提出了交流极化 - 电磁力的理论。最后，探索了磁场强度对脱水性能的影响，包括脱水深度和脱水速度，并获得了该实验中的最佳磁场强度范围，其值为[0.269，0.355]T。
Electromagnetic synergistic oil-water separation is a promising technology for deep dehydration with higher efficiency, shorter dehydration period and flexible control of field parameters. In this paper, non-conductive silicone oil without colloid and asphaltene was used as the continuous phase. The effect of magnetization and Lorentz force on the continuous phase can be excluded to explore the mechanism of the electric field and magnetic field synergistic dehydration. Firstly, the particle size of droplets was characterized. The results showed that the dispersed phase was uniformly distributed and the average particle size was 18.24 um. Then the dehydration performance of different types of outfields was compared. The experimental results showed that the dehydration performance of AC electric field combined with magnetic field was better than that of single AC electric field. The dehydration performance of AC electric field and magnetic field was better than that of DC electric field and magnetic field. On this basis, the theory of AC polarization-electromagnetic force was proposed. Finally, the influence of magnetic field intensity on dehydration performance was explored, including dehydration depth and dehydration speed, and the optimal magnetic field intensity range in this experiment was obtained, and its value was [0.269, 0.355] T.
