摘要： Abstract The present invention discloses a chaotic frequency pulsed electric field demulsification method and system for waste oil emulsion. Firstly, a chaotic frequency pulsed electric field with constant amplitude and equal pulse width is generated by adjusting the chaotic pulse frequency. The chaotic frequency includes the resonant frequency of the emulsion droplet. Then the chaotic frequency pulsed electric field is applied to the waste oil emulsion for demulsification and dehydration. The method for demulsification of waste oil emulsion with chaotic frequency pulsed electric field provided by the invention applies the method of chaotic frequency electric field with constant amplitude and equal pulse width in view of the characteristics of demulsification and dehydration of the pulsed electric field to make up for the shortcoming that the common constant pulsed electric field cannot cover the resonant frequency of the droplet in the emulsified oil. Constant amplitude and equal pulse width can avoid the influence of demulsification efficiency due to the uncertainty of electric field amplitude and pulse width. The chaotic, adjustable and controllable pulse frequency can realize the full coverage of the electric field resonance frequency of the emulsified droplets, give full play to the maximum efficiency of electric field demulsification, and meet the requirements of efficient demulsification and dehydration in the process of industrial waste oil recycling.
