Heat strengthening of double-field coupling demulsification of industrial waste oil emulsion
Demulsification of highly aqueous waste oil is difficult to complete by a single process efficiently. The dewatering-type hydrocyclone is used as the unit body and includes the high-voltage electrode to realize demulsification and dewatering ability of the coupling of high-voltage electric and swirling centrifugal fields in waste oil emulsion efficiently. This study considers the influence of heating temperature on demulsification in coupled field. Thus, a heat-strengthening double-field demulsification process is proposed. Specifically, the effect of heat strengthening on demulsification, dewatering, and separation of double-field coupled by numerical simulation and experimental methods was investigated. The temperatures of heat-strengthening were 60?°C, 65?°C, 70?°C, and 75?°C. The results show that the separation efficiency predicted by numerical simulation are in good agreement with the experimental results. And the heat-strengthening can effectively enhance the separation effect of two fields and improve the efficiency of the oil–water separation of industrial waste oil. When the heating temperature is raised from 60 to 65?°C, and from 65 to 70?°C, the separation efficiency increases by approximately 4.1% and 6.7%, respectively.
