旋流气浮技术作为新一代油水分离技术具有极大的应用潜力。从旋流气浮技术工艺原理出发，考察了溶气压力、气液比和旋流强度等因素对生成气泡的影响，对旋流气浮的浮选效率进行了分析。结果表明，溶气压力、气液比和旋流强度能直接影响气泡的生成尺寸和分布概率密度，进而决定气浮设备的浮选性能，同时根据单因素方差分析表明这3种因子的最适水平分别为500 kPa、6%和20g（g=9.8 m/s²）；利用正交实验设计，综合评估溶气压力、气液比和旋流强度对浮选性能的影响，结果表明，当溶气压力为600 kPa、气液比约为6%、旋流强度约为18g时，设备整体运行效果最佳，此时的油品去除率不低于90%，悬浮物去除率不低于81%。

As a new generation of oil-water separation technology, cyclone gas flotation technology has a great application potential.The process principle of cyclone gas flotation technology is explored, and the influences of the pressure of dissolved gas, the ratio of gas to liquid, swirling intensity and other factors on bubble formation are investigated.The oil-removing efficiency of cyclone gas flotation is analyzed.Results show that the pressure of dissolved gas, the ratio of gas to liquid and the swirling intensity all can directly affect the bubble size and distribution probability density.Furthermore, the flotation performance of gas floatation equipment is determined, and the optimal levels of these three factors are obtained as 500 kPa, 6% and 20g, respectively through single-factor analysis of variance.As the orthogonal experimental design is utilized to comprehensively evaluate the effects of the pressure of dissolved gas, the ratio of gas to liquid, the swirling intensity on flotation performance, it is found that the overall performance of the equipment reaches the best when the pressure of dissolved gas is 600 kPa, the ratio of gas to liquid is about 6% and the swirling intensity is around 18g.The removal rates of oil and suspended matters are not less than 90% and 81%, respectively under these conditions.
