摘要
将轴流式离心分离技术引入沸腾制粒机中,以期提升沸腾制粒机的工作效能。提出一种基于代理模型的轴流式旋风分离器结构参数多目标优化设计方法。以计算流体动力学(CFD)为基础,采用田口法进行试验规划,构建关于分离效率和压降的响应面回归方程,利用NSGA-II求解得到多目标优化模型的Pareto前沿。结果表明:优化结构对(1~10)um微细颗粒的分离效率达到61%,相较初始值提高了24%,在较高的操作条件下可达到90%,性能指标满足其在沸腾制粒机除尘系统中的应用要求,研究结果也为轴流式旋风分离器的设计与优化提供了依据。
The axial flow centrifugal separation technology was introduced into the fluid bed granulation to improve the working efficiency.A multi-objective optimal design method for axial cyclone separator structure parameters based on agent model.Based on Computational Fluid Dynamics(CFD),the Taguchi method is used for experimental planning,a response surface model on separation efficiency and pressure drop was constructed,NSGA-II was used to search for the Pareto optimal solution front for multi-objective optimization model.The results show that the optimized structure's separation efficiency for fine dust of(1~10)um is 24% higher than the initial value,and its value is 61%,which can reach 90% under higher operating conditions,the performance index meets its application requirements in the fluid bed granulation dust removal system,the research results also provide a basis for the design and optimization of the axial cyclone dust separator.
