Separation performance of hydrocyclone on emulsified oil wastewater floc

In order to improve the separation effect of emulsified oil wastewater flocs, a new separation method was proposed, which used a hydrocyclone to separate emulsified oil flocs. In this paper, the velocity field, pressure loss and floc volume distribution of the two hydrocyclones were studied by numerical simulation, and the difference of the separation performance of two different structures was investigated. The results show that the separation efficiency reaches to 81.7% and 78.9% respectively; the single cone cyclone has smaller pressure loss and energy loss under the same processing capacity; as the particle size of the floc increases, the separation efficiency of the two hydrocyclones increases. This simulation provides a reference for deep treatment of emulsified oil wastewater.
