Simulation Analysis And Experimental Study On A New Type Spiral Inlet Hydrocyclone

Based on the traditional liquid-liquid hydrocyclone,the structure has carried on the innovation.The aim is to ensure that its have larger capacity and higher separation efficiency,on the basis of it to achieve miniaturization of structure size.So a new type spiral inlet hydrocyclone will be invented,based on the improved hydrocyclone to meet the requirements of structure miniaturization.Through liquid axially into the cyclone can adapt to the narrow working environment(such as downhole string,etc.).Using the Fluent software can simulate and analyze the spiral inlet hydrocyclone.The Fluent software can analyze internal flow field characteristics of cyclone.The separation mechanism of cyclone can be mastered by analyzing the effects of changing parameters of spiral inlet structure on the pressure field and velocity field.At the same time,it also can determine the best operating parameters and structure size of the cyclone.Different flow rate,split ratio on the new type of cyclone separation efficiency can be achieved by experimental verification.Also can test the feasibility and its deoiling effect of new type spiral inlet hydrocyclone prototype.When change operating parameters,new type hydrocyclone under the reasonable operating parameters can achieve high separation efficiency,complying with software simulation analysis results.Analyzing the results of the experimental data and simulation conclusion shows that it is feasible to innovate and optimize the structure of cyclone with Fluent soft ware,also operating parameters can be optimized and selected by using the method of numerical simulation.Finally,the prototype of new type hydrocyclone appeared the problems during the experiment are analyzed and summarized,these will laid a good foundation for future application in the downhole oil-water separation.
