Problems solved by technology

[0005] The purpose of the present invention is to propose a high-voltage pulse electric field-swirl centrifuge for the problems of long time consumption, high energy consumption, and poor treatment effect in the demulsification and dehydration of high-water lubricating oil in traditional processes such as vacuum heating and separation. Field joint lubricating oil demulsification and dehydration device, high-voltage pulse electric field is used to complete the rapid coalescence of emulsified droplets in lubricating oil and the settlement of large droplets, and the swirl centrifugal field is used to quickly remove medium and small droplets in lubricating oil. The effective synergy between the high-voltage pulsed electric field and the swirling centrifugal field improves the demulsification and dehydration efficiency and realizes the rapid and efficient demulsification and dehydration of lubricating oil
