中文摘要：逆向-并向流卧式气浮器具有气泡与絮体碰撞和黏附接触效率高、结合成的泡絮体稳定等优点,采用欧拉多相流模型和realizable k-ε湍流模型进行流体动力学(CFD)数值模拟,研究了结构参数和运行参数对其内部流态和流场的影响。模拟结果表明,挡流板高度为1000mm,并向接触区的距离为250mm,溶气口1到左壁面距离为90mm、溶气口2到左壁面距离为340mm,气泡直径为30μm,回流比为10%时,逆向-并向流卧式气浮器的流态和流场分布合理,气浮除油环境极佳。

外文摘要：The reverse-parallel flow horizontal air floats have the advantages of high collision efficiency and adhe-sion contact between bubbles and flocs,and the stability of the combined flocs.The Euler multiphase flow model and realizable k-εturbulence model were used for CFD numerical simulation to study the effects of structural and operating parameters on the internal flow state and flow field.The simulation results showed that the height of the baffle was 1000 mm,and the distance to the contact area was 250 mm,the distance from the dissolved air inlet 1 to the left wall was 90 mm,the distance from the dissolved air inlet 2 to the left wall was 340 mm,the bubble diameter was 30μm,and the reflux ratio was 10%the flow pattern and flow field distribution of the reverse and parallel flow horizontal air float were reasonable.Air float oil removal environment was excellent.
