Experiment And Application Basis Study Of Gas-injected Hydrocyclone

Gas-injected liquid-liquid hydrocyclone, a new kind of high efficient centrifugal separation equipment, developed based on the normal used liquid-liquid hydrocyclone. It has many virtues, such as small volume, large capacity, small cut size and high floatation speed.By mechanism analyzing and experiment study, the separation mechanism and characteristic of the gas-injected liquid-liquid Hydrocyclone were studied.Through the numerical simulation, the optimal structure sizes of liquid-liquid hydrocyclone were obtained, such as the inlet area, the overflow gate diameter, the enter length of overflow, and so on. And has carried on the experimental verification to the optimal most superior parameter. The contrast to the simple point gas injection and the micro-pore gas injection of big cone and small cone were carried on, the more appropriate gas injection way was chosen—the gas injection of small cone. The influence of separation performance was studied of split, flowrate and the gas injection measures.Through the oil field test, the optimal design parameter and the experimental parameter obtained in laboratory experiment were made further confirmation, which explained the gas injection may improve the processing effect of hydrocyclone to the sewage. The scene complex operating mode was able to adapt by the gas injected liquid-liquid hydrocyclone, which has certain handling ability to the sewage.Through the development hydrocyclone craft system reliability analysis, the improvement system reliable measure has been analyzed.This work provided theoretical base and experience for further research of the separation mechanism, separation characteristic and structural optimization design of the gas-injected liquid-liquid hydrocyclones. It has laid the foundation for the hydrycyclone and work system's application...
