摘　　要：目前T型管式分离技术分离效率较低,为提高油水分离效率,提出一种U型管式分离结构。为验证新型管式分离结构的性能,利用Fluent定量研究了外部参数对U型管油水分离装置内部流场的变化规律,主要研究因素包括入口速度、入口含油率、旋转半径、油滴粒径等参数对U型管分离效率的影响。主要得出如下结论:混合物入口速度对分离效率影响较大,随着入口速度的增大,油水分离率分离率减小;油水分离率随着U型管旋转半径增大而增大,但当旋转半径超过0.6 m时,分离效率不再显著增加;油水分离率随着油滴粒径的增大而逐渐提高。研究结论为油水分离U型管设计提供了参考。To improve the oil-water separation efficiency,a U-tube separation structure is proposed since the seperation efficiency of the existing T-tube separation technology is relatively low.In order to verify the performance of the new tubular separation structure,the variation of the internal flow field of the U-tube oil-water separation device is studied by Fluent quantitative analysis.The research mainly focuses on the influence of some external parameters such as inlet velocity,inlet oil content,rotation radius,oil droplet size andαangle on the separation efficiency of the U-tube.The main conclusions are as follows:the inlet velocity of the mixture has a great influence on the separation efficiency.The oil-water separation rate decreases with the increase of the inlet velocity,the oil-water separation rate increases with the increase of the rotation radius of the U-tube,but when the radius of rotation exceeds 0.6 m,the separation efficiency no longer increases significantly,and the oil-water separation rate gradually increases as the oil droplet size increases.The research results provide a reference for the design of oil-water separation U-tube.
