In order to improve the hydrodynamic characteristics and reduce energy consumption of reciprocating plate column，an energy saving reciprocating plate column based on electro‑permanent magnet technology was proposed. Through the finite element simulation of magnetic field，the average magnetic induction intensity of the electro‑permanent magnet device was 1.48 T，which satisfies its feasibility as a driving mechanism. Subsequently，the water-kerosene system was used in a reciprocating plate column with an inner diameter of 55 mm. The results show that with the increase of vibration frequency，the ratio of dispersed holdup decreases first and then increases，up to 16.7%；The sauter mean diameter decreases with the increase of vibration frequency，and the minimum is 2.75 mm；Due to the introduction of the electro‑permanent magnet device，the reciprocating plate column can enter the dispersion zone when the vibration frequency is higher than 1 time/min；Under low frequency vibration，the reciprocating plate column exhibits a mass transfer surface area of up to 314.5 m-1；The electro‑permanent magnet device consumes only 450.8 J/min，indicating a significant energy‑saving effect.The research provides a theoretical basis for the promotion and application of reciprocating plate column based on electro‑permanent magnet technology in processes such as mixing and separation.
