摘　　要：针对常规双锥旋流器对小粒径油滴难以分离的问题,设计了一种主直径为20 mm的微型旋流器。为进一步增强微型旋流器的分离性能,利用PB试验和响应面分析法的CCD (中心组合设计)试验对影响微型旋流器分离性能的结构参数进行优化。PB试验对影响微型旋流器分离性能的6个因素进行了评价,筛选出具有显著效应的大锥角和溢流管直径两个因素;采用RSM试验设计确定了主要影响因素的最优结构参数值:大锥角为15.28°和溢流管直径为7.25 mm;明确了大锥角与溢流管直径对分离效率的交互影响关系,分别构建了分离性能与待优化参数的数学模型。通过数值模拟,对完成结构优化的微型旋流器进行分离性能验证,结果表明,分离效率较优化前的91.15%提升至优化后的93.77%,分离效率可提升2.62个百分点,该研究为微型旋流器分离性能的进一步提升提供了优化思路。Aiming at the problem that small-sized oil droplets are difficult to separate with conven-tional double-cone hydrocyclones,a mini hydrocyclone with a main diameter of 20 mm is designed.To further enhance the separation performance of the mini hydrocyclone,the structural parameters af-fecting the separation performance are optimized by Plackett-Burman(PB)test and CCD(Center Com-bination Design)test of Response Surface Methodology(RSM).Six factors that affect the separation per-formance of the mini hydrocyclone are evaluated by the PB test,and two key factors with significant ef-fects are screened:overflow pipe diameter and large cone angle.The optimal structural parameter values of the main influencing factors are determined by RSM test:the large cone angle is 15.28°and the overflow pipe diameter is 7.25 mm.Also,the interaction between the large cone angle and the over-flow pipe diameter on the separation efficiency is clarified,and the mathematical models for separation performance and the two parameters to be optimized are built,respectively.Through numerical simula-tion,the separation performance of the optimized mini hydrocyclone is verified.The results show that the separation efficiency is increased from 91.15%before optimization to 93.77%after optimization,i.e.,the separation efficiency can be improved by 2.62%.This study provides an optimization idea for the further improvement of the separation performance of mini hydrocyclones.
