Coupling Unit of Demulsification Device and Structural Optimization

Abstract

The demulsification dehydration of emulsified lubricating oil is very important in the resource recycling process of industrial waste oil. At present, it is difficult for traditional dehydration processes and devices to accomplish the demulsification dehydration treatment of waste oil with water quickly and efficiently. The coupling of high-voltage pulsed electric field and jet centrifugal field is put forward to accomplish the dehydration of emulsified oil rapidly. By the design of technological process and the use of FLUENT software, the optimal structure parameters of coupling unit, which is applied on the demulsification dehydration treatment of waste oil, are obtained. The double-field coupling demulsification device is designed and manufactured. The performance test results show that, the experimental results are basically consistent with the numerical simulation results, the double-field coupling demulsification dehydration device has a stable working performance and can achieve the oil-water separation of emulsified oil effectively and rapidly.
