Spiral guide vanes are often used to improve the collection efficiency of cyclone separators, but they are closely related to the parameter variables of the guide vanes. To further improve the performance of the equipment, the separator and spiral guide vanes need to be optimized. In this study, the performance characteristics of the flat-roof (FR) and spiral-roof (SR) separators were compared, and then the multiobjective optimization of the guide vanes was carried out. The design relationship between the parameters of the spiral guide vanes (pitch, number of turns, and side wall clearance) was analyzed and the optimal values were determined. computational fluid dynamics (CFD) and response surface modeling (RSM) were used to obtain precise output responses, while precise fitness functions were constructed between design variables and objectives (efficiency and pressure drop). Finally, the optimal structure design was carried out through a genetic algorithm (GA). The results show that, under the same conditions, the SR separator configured with guide vanes can reduce the pressure drop by 7.9% while ensuring the same collection efficiency. At the same time, compared with the FR separator, the optimal structure selected reduces the cutting particle size by 22.9%. This article gives the optimal performance design solution, which can select appropriate structural parameters according to the specific requirements of efficiency and pressure drop. It can provide an effective reference for the subsequent design and application of spiral vanes.

提高旋风分离器分离性能的螺旋导叶多目标优化


螺旋导叶常用于提高旋风分离器的收集效率，但与导叶的参数变量密切相关。为了进一步提高设备的性能，需要对分离器和螺旋导叶进行优化。本研究比较了平顶（FR）和螺旋顶（SR）分离器的性能特点，然后对导叶进行了多目标优化。分析了螺旋导叶参数（螺距、圈数、侧壁间隙）之间的设计关系，确定了最佳值。使用计算流体动力学（CFD）和响应面建模（RSM）来获得精确的输出响应，同时在设计变量和目标（效率和压降）之间构建精确的适应度函数。最后，通过遗传算法（GA）进行优化结构设计。结果表明，在同等条件下，配置导叶的SR分离器在保证相同收集效率的情况下，压降可降低7.9%。同时，与FR分离机相比，所选的优化结构使切割粒度减小了22.9%。本文给出了最优性能设计方案，可以根据效率和压降的具体要求选择合适的结构参数。可为后续螺旋叶片的设计和应用提供有效的参考。
