摘　　要：电除尘器电场进出口气流分布的均匀性是影响电除尘器除尘效率的重要因素。基于计算流体力学(CFD)技术,采用fluent软件平台,通过对方形和圆筒形两种外形转炉煤气用电除尘器的气流分布进行数值模拟计算,比较了两种外形电除尘器的气流分布差异,说明了圆筒形电除尘器较方形电除尘器气流分布状态的优越性。Electric field uniformity of import and export of electrical precipitator flow distribution is the main factor that affects the efficiency of electrostatic precipitators. On the bases of computational fluid dynamic( CFD) method,the airflow distribution of rectangular and cylindrical shape of electricity precipitator for converter gas were simulated using fluent software platform.Compared the difference between the gas flow distribution of two electrostatic precipitators,the study illustrated superiority of gas flow distribution in cylindrical electrostatic precipitator.
