摘　　要：利用CFD方法对燃煤电厂电改袋式除尘器气流分布进行数值分析,给出了袋式除尘器箱体流量分配,每个滤袋单元处理风量、滤袋迎面气流速度大小和分布。数值分析结果与模型试验、现场测试结果基本吻合,可作为除尘器结构设计优化的依据。The gas flow distribution of bag filter reformed from ESP in Jiaozuo coalfired Power Plant has been analyzed numerically by using computational fluid dynamics method. Through the numerical analysis, the filter box flow capacity assignment,operation air volume of every filter bag cell, head - on gas flow velocity distribution of a filter bag are discussed. The calculated results are consistent with the model experimental and measured results basically. The results provide the basis of structure design optimization of bag filter.
