Structure Design Of Inner-cone Type Gas-liquid Cylindrical Cyclone And Its Optimization

Gas-Liquid Cylindrical Cyclone (GLCC) has the advantages of small volume, simplestructure, low energy consumption, light weight, convenient application, large processingquantity, the separation effect of stability and other advantages. So it has broad applicationprospects. GLCC with cone (Inner-Cone Type Gas-Liquid Cylindrical Cyclone) is a new typeof high efficiency centrifugal separation device, it is based on the structure of GLCC. Thisarticle studies of the feasibility of the application on Inner-Cone Type Gas-Liquid CylindricalCyclone in oilfield produced liquid.According to the trend of the current oilfield produced liquid containing a large quantitygas, combining with the structure of original GLCC, we determine the new scheme of thecyclone separating, testing for gas separation effect. Based on the conventional GLCC forresearch reference object, through the numerical simulation to calculate the simulation andstructure optimization design, with the Reynolds stress turbulence model and the SIMPLECalgorithm, obtaining the pressure drop distribution characteristics and separation efficiencycharacteristics of the gas-liquid two-phase. Through the simulation and analysis of the effectof separating a gas-liquid mixture, gradually improved structure, has reasonable structuremodel.According to the simulation results, manufacture the test prototype. Based on theexperimental study of new structure GLCC numerical simulation, compared to the results ofnumerical simulation, this article proved that it is feasible to design and optimize the structureof Inner-Cone Type Gas-Liquid Cylindrical Cyclone, and the optimization parameter isreasonable.The content of this article provide certain theoretical basis for further study of thegas-liquid cyclone separator separation mechanism and the structure optimization.
