| Gas-liquid cyclone separation technology is widely used in petrochemical,biological,environmental protection and other industries.Previously,researchers developed a high-efficiency tangential inlet cyclone separator by learning from the gas-solid separator with the same separation mechanism,studying the flow characteristics and optimizing it in combination with the actual situation of gas-liquid separation,which has achieved good separation effect and broad industrial application prospects.In the practical industrial application,in order to meet the large processing capacity,relying on the simple similarity principle to enlarge the traditional high-efficiency cyclone separator,or connecting multiple cyclones in parallel,there are some problems and potential safety hazards,such as low separation efficiency,uneven two-phase flow and so on.On the basis of increasing the number of cyclone separators,the performance is improved.In this paper,the effects of inlet number on gas-liquid two-phase flow characteristics,pressure drop and separation efficiency of gas-liquid cyclone separator are investigated by using RSM and DPM models.At the same time,the effects of possible feed heterogeneity on liquid phase distribution and performance in practical industrial application are analyzed.The results show that compared with the single-inlet structure,the multi-inlet cyclone separator presents good symmetry in the distribution of velocity field and pressure field,which can improve the flow pattern of vortex,improve the stability of flow,inhibit the secondary flow and short-circuit flow to a certain extent,and the increase of the number of inlets can also improve the pressure drop and separation efficiency.Among them,the even inlet structure has an effect on the symmetry of flow field The stability and separation performance have been further improved. |
