摘要
将重力沉降和旋流分离相结合设计了一种紧凑型立式三相分离器。利用两相流理论建立了油水分离过程的数值计算模型,并对4种结构进行了四因素四水平的正交实验。结果表明,入口管径对分离效果影响显著,起旋管长度影响次之,排油管入口高度对分离效率有一定影响,起旋管径对分离效果的影响最小。最优结构方案为入口管径D 1=60 mm,起旋管长L=350 mm,起旋管径d 2=110 mm,排油管入口高度h=80 mm,此时,分离效率为96%。最优结构的单因素实验表明,处理量和分流比对分离性能影响显著,处理量越小和分流比越大,油水分离效率越高。
An efficient and compact vertical three-phase separator was designed by combining gravity settlement with cyclone separation.A numerical model for the oil-water separation process in a three-phase separator is established based on two-phase flow theory.Four factors and four levels of orthogonal experiments were carried out on four structures.The results show that the inlet diameter has a significant effect on separation efficiency,and the larger the inlet diameter,the higher the separation efficiency;the length of the spinning tube,which has a second effect,is inversely proportional to the separation efficiency;the inlet height of the draw-off pipe also has a certain effect on the separation efficiency,and the latter increases as the former increases;the diameter of the spinning tube has the smallest effect on the separation efficiency;the optimal structure scheme is the inlet diameter D 1=60 mm,besides the length and the diameter of the spinning tube are L=350 mm and d 2=110 mm,respectively.This structural scheme allows separation efficiency of up to 96%.The single factor experiment on the optimal structure shows that the treatment capacity and split ratio have a significant impact on the three-phase separator.To sum up,the smaller the treatment capacity and the larger the split ratio,the higher the oil-water separation efficiency.
