Optimization of the inlet velocity and pipe structure of electrostatic fabric integrated precipitator was numerically simulated by computational fluid dynamic (CFD) software through changing the inlet velocity ,increasing the length before the electric coagulator ,and adding flow deflectors in the last elbows of inlet pipe .Results showed that inlet velocity had little influence on the dust removal efficiency but adding flow deflectors had great influence . When the inlet velocity was 18 .00 m/s ,the length before the electric coagulator was 0 .50 m ,and 3 flow deflectors were added ,the velocity distribution of both electric coagulator and electrostatic precipitator tended to be uniform .The mean square root were 0 .17 and 0 .14 ,respectively .Vortex was almost disapperared .%利用计算流体动力学(CFD)软件对电袋复合除尘器进行数值模拟,通过改变气流入口流速 、调整电凝并区前水平管道长度和增设入口管道内导流板等方法进行优化.结果表明,气流入口流速对改善电袋复合除尘器的除尘效果影响不大,而入口管道增设导流板影响很大.当气流入口流速为18.00 m/s、电凝并区前水平管道长度为0.50 m、入口管道后一弯管处增设置3块导流板时,电凝并区入口断面 、电除尘区入口断面气流分布均匀,相对均方根分别为0.17、0.14,涡流区域基本消失.
