气浮-旋流组合式含油废水分离器数值模拟及优化设计

Experimental research and numerical simulation were done for the oily wastewater separator integrated cyclone and floation unit prototype. Results show that the separator has effect for the small particle diameter emulsified droplets of low concentration oily wastewater, but the highest separation efficiency of the model is only 50%, which cannot meet the application requirements. The numerical simulation was in good agreement with the experimental results which verify the reliability of the simulation. Authors analyzed the causes of lower separator efficiency, further optimized the structure. The optimized model was predicted through the verified numerical simulation method, the highest separation efficiency of the new model can reach 78%, which provide a reference for the further study and optimization of this type separator.
