Optimization of structural parameters of axial flow two-stage integrated hydrocyclone
摘要
Abstract
In order to realize the efficient separation of oil and water in the limited space such as the downhole of the oil production wellbore,a new axial-flow two-stage integrated hydrocyclone was designed,the influence of nine different structural parameters of hydrocyclone on the separation performance was systematically studied by numerical simulation.The results were tested and verified.According to the influence of various structural parameters on the separation efficiency of the hydrocyclone,the optimal structural parameters were determined,under this parameter,the highest separation efficiency is 96.38%,and the overflow pressure drop is 89.42 kPa.This study focuses on the reasons why the effect of the change of the secondary steady flow cone angle parameters on the quality efficiency is not stable.It is found that when the specific secondary steady flow cone angle is 12 °,there is no circulating flow at the outer wall of the secondary steady flow cone angle,and there is a backflow phenomenon above the total overflow port,which can maximize the separation efficiency.The circulating flow and reflux in the hydrocyclone also affect the change of pressure drop,and increasing the overflow pressure drop is more conducive to oil phase separation.The research can provide reference for the structural design and practical application of hydrocyclone.关键词
