摘　　要：工业除尘器作为工业安全生产、绿色制造的重要装置,如何提高其除尘效率和降低耗能是未来产品的发展方向。针对除尘器滤筒仓核心部分,选取滤筒安装位置A、底部漏斗结构B和扰流板长度C三因素二水平进行全因子流场仿真优化实验,以过滤总流量与流量综合不均系数作为评价指标,对实验数据进行极差分析获得最优组合。仿真结果表明,改进机型相较原型机,过滤总流量提升了4.21%,流量综合不均系数降低了75.75%,并解决了位于进气口处的滤筒易受气流冲蚀作用与滤筒仓内存在二次扬尘的问题。根据仿真结果试制了改进机型,改进机型的实际过滤总流量测试与仿真计算得到的过滤总流量误差为0.54%,数值仿真优化方法能有效指导滤筒除尘器优化设计,有利于延长滤筒的使用寿命和提高产品品质。Industrial dust collector is an important device for industrial safety production and green manufacturing.How to improve dust removal efficiency and reduce energy consumption is the development direction of future products.For the core part of the filter silo of the dust collector,three factors and two levels of the filter cartridge installation position A,the bottom funnel structure B and the spoiler length C were selected to carry out the full-factor flow field simulation optimization test.The total filtration flow and the comprehensive flow uneven coefficient were taken as the evaluation index,and the optimal combination of the test data was obtained by range analysis.The simulation results show that compared with the prototype,the improved cartridge dust collector can increase the total filtration flow by 4.21%,and reduce the comprehensive flow uneven coefficient by 75.75%,and solve the problem that the filter cartridge located at the air inlet is vulnerable to airflow erosion and secondary dust in the filter silo.According to the numerical simulation results,an improved cartridge dust collector was produced,and the error of the actual total filtration flow of the improved cartridge dust collector was 0.54%.The numerical simulation optimization method can effectively guide the optimization design of cartridge dust collector,and is conducive to extending the service life of the filter cartridge and improving the product quality.
