摘要
运用CFD方法对不同入流含油率、动力黏度以及油滴粒径下的紧凑型油水分离器进行研究,以得到油水分界层高度的变化规律,为工业生产提供技术支持。结果表明,随着入流含油率的增加,分界层高度逐渐变大,当入流含油率达到20%时,分界层高度趋于稳定。通过改变油相粒径及油相动力黏度发现,随着两者的增加,分界层高度逐渐减小,分离器上方的油相区域增大,有利于油水分离过程的进行。在入流含油率及油相物性一定的情况下,分界层高度与流动长度(x/D)的呈反比关系,表明分界层高度与分离效率之间存在必然联系。
CFD method was used to study the compact oil-water separator under different inflow oil content,dynamic viscosity and oil droplet size,so as to obtain the variation law of oil-water boundary layer height and provide technical support for industrial production.The results showed that the height of the boundary layer gradually increased with the increase of the inflow oil content.When the inflow oil content reached 20%,the height of the boundary layer tended to be stable.By changing the oil phase particle size and oil phase dynamic viscosity,it was found that with the increase of the two,the height of the boundary layer gradually decreased and the oil phase area above the separator increased,which was conducive to the process of oil-water separation.When the inflow oil content and oil phase physical properties were constant,the relationship between boundary layer height and flow length(x/D)was inversely proportional,indicating that there was an inevitable relationship between boundary layer height and separation efficiency.
