摘要：采用流体力学软件对不同结构径向入口旋风分离器的气固两相流场进行了数值模拟,并基于响应曲面法得到旋风分离器的压降模型及分离效率模型。结果表明升气管直径和入口角度对旋风分离器的分离性能影响较大,且两者对旋风分离器分离性能的影响有着很强的交互作用;直筒段高度、锥体高度及升气管插入深度对分离性能影响相对较弱;下降管直径对分离效率影响较大,但对压降影响较弱;随着下降管长度的增大,压降不断增大,分离效率先减小后增大;在考虑压降及分离效率权重的基础上,得到了最优性能的旋风分离器结构,通过比较该结构旋风分离器的分离性能,发现模拟值和模型预测值吻合良好。
Numerical simulations of cyclone separators with various geometries were performed for the optimization of their structure.Based on response surface methodology and using the statistical software program（SAS）,the prediction models of the pressure drop and the separation efficiency for particles with diameter of 1 μm were obtained.The results show that the vortex finder diameter and inlet angle have significant effect on the cyclone performance and they also have strong interactions on the separate performance of cyclone separator.Relatively,the effect of cylinder height,cone height and vortex finder height on the separation performance is weaker.The cone bottom diameters have greater impact on separation efficiency,but weaker influence on the pressure drop.With increasing the lower cone height,the pressure drop increases,and separation efficiency decreases initially and then increases.Under the consideration of obtaining the minimum pressure drop and maximum separation efficiency,the structure parameters of the cyclone separator with optimum performance were obtained.Via the comparison of the separation performance of the obtained cyclone separator with optimum performance,it was found that the prediction values of models are in good agreement with the values of numerical simulation.
