In the high efficiency oil removal technology aspect, the theory study and application experiment of air sparged liquid-liquid hydrocyclone was carried out, enlightened by the air sparged solid-liquid hydrocyclone. Firstly, the strength and movement of dispersed phase was analyzed in theory, it was proved that the air bubble-oil drop polymer trend to move to the axes of hydrocyclone. Secondly, using CFD method, the characteristics of oil-air-water flow field were studied, including velocity distribution, pressure distribution, turbulent motion energy and its dissipation distribution. The characteristics and separation effect under different air injection methods were simulated. Thirdly, the separation ex-periment of air sparged liquid-liquid hydrocyclone was carried out at Lab. The major structure parameters of the hydrocyclone were optimized, the reasonable air injection method and performance parameters were determined through 4 groups of air injection experiments.
