反射式入流构件对重力油水分离器流动均匀性的影响及结构优化

文章导读

摘要为探究反射式入流构件结构参数及安装方式对重力油水分离器流动均匀性的影响规律并确定优化结构参数,通过Fluent软件对油水分离器进行模拟研究。结果表明,流速平均均匀度N与入流构件射流距离d、入流角度θ和入流口垂直位置h均呈先增大后减小的规律,分别在d=0.075D、θ=90°、h=0.25D处N取得极大值,且下装方式的流场均匀性好于上装方式;随着入流雷诺数(Re_i)的增大,分离器流场均匀性逐渐变差;下装反射式入流构件的流场均匀性优于下管箱式入流构件;单参数下入流构件的最优值与响应面分析法优化结果相差不大,优化结构参数分别为h=0.25D,d=0.07D,θ=90°。

Abstract： In order to explore the influence of the structural parameters and installation methods of the reflective inlet component on the flow uniformity of the gravity oil-water separator and determine the optimal structural parameters, the Fluent software is adopted to numerically simulate the oil-water separator. The results show that as the jet distance d, the inflow angle θ and the vertical position of the inlet port h increase, the average uniformity of flow rate N increase first and then decrease. When d=0.075D, θ=90°, h=0.25D respectively, the maximum value of N is obtained, and the uniformity of the flow field of the bottom device is better than that of the top device. As the inflow Reynolds number(Re_i) increases, the uniformity of the flow field gradually deteriorates; the uniformity of the flow field of the bottom-mounted reflective inlet component is better than that of the down-tube box-type inlet component; the optimal value under a single parameter of the reflective inlet component is not much different from the optimization result of response surface analysis, the optimized parameters are as follows: h=0.25D, d=0.07D, θ=90°.
