摘　　要：以某钢铁厂烧结湿式电除尘器为研究对象,采用计算流体力学数值计算方法,模拟分析其优化前后的流场分布情况。模拟结果表明,通过在适当位置增设导流板组、整流格栅、陶瓷填料多孔分布板以及对连接烟道的改造(直角弯→圆弧弯)等方法,可使得湿电流场均布情况得以明显优化,可为同类装置的湿式静电除尘器设计及改造提供借鉴参考。Taking a sintering wet electrostatic precipitator in an iron and steel plant as an example,the flow field distribution before and after optimization was simulated and analyzed by using computational fluid dynamics(CFD)numerical simulation method.The simulation results show that the uniform distribution of wet current field can be obviously optimized by adding guide plate groups,rectifying grid,Ceramic packing porous distribution plate and the transformation of connecting flue(right angle bending to arc bending),which can provide reference for the wet electricity design and transformation of similar devices.
