摘　　要：针对当前KJS-Y系列矿用降尘器性能不佳以及叶片使用寿命不长的问题,采用流固耦合方法,分别对不同叶轮叶片的降尘器进行数值模拟,分析空气的运动轨迹以及降尘器内部流场的应力分布特性。结果表明前掠、弯掠叶片能够有效改善叶顶处流体流动不稳定的情况,同时采用弯掠叶片能够增强叶片的强度,提升降尘器的性能,同时延长了叶片寿命。对KJS-Y系列矿用降尘器的叶片优化和寿命延长提供了理论和技术基础。In order to solve the problems of poor performance of KJS-Y series mine dust collector and short service life of blades,the fluid-structure coupling method was adopted to carry out numerical simulation of the dust collector with different impeller blades,and the air movement trajectory and the stress distribution characteristics of the flow field in the dust collector were analyzed.The results show that the forward swept and curved swept blades can effectively improve the fluid flow instability at the tip,and the curved swept blade can enhance the strength of the blade,improve the performance of the dust collector,and prolong the blade life.Provide theoretical and technical basis for blade optimization and life prolongation of KJS-Y series mine dust collector.
