鉴于单一物理手段难以实现乳化油的高效破乳脱水处理，提出了一种高压脉冲电场-旋流离心场联合实现乳化油的破乳脱水工艺，并利用三维建模设计了相应的双场联合破乳脱水装置。从非线性振动动力学理论的角度得到了高压脉冲电场单元的最佳工作电场参数，并运用数值的方法，确定了旋流离心场单元最佳工作参数。通过双场联合破乳脱水装置试验结果表明，高压脉冲电场-旋流离心场联合作用能对废油乳化液进行高效破乳脱水，破乳脱水效率要高于单一旋流离心场的脱水效率。

Considering that single physical method is difficult to realize efficiently demulsification and dewatering treatment of emulsified oil,the technology combining high voltage pulsed electric field with swirl centrifugal field is put forward to achieve demulsification and dewatering to emulsified oil.The corresponding equipment is designed by using three-dimensional modeling.The optimal working electrical field parameters for high voltage pulsed electric field unit are obtained from the perspective of the nonlinear vibration dynamic theory.The optimal operating parameters for the swirl centrifugal field unit are obtained by applying numerical method.The results of experiments performed on the two-field combined demulsification and dewatering equipment indicate that the combining action of these two fields can accomplish efficiently demulsification and dewatering to waste emulsified oil,with higher efficiency compared with that by swirl centrifugal field alone.
