摘　　要：利用Fluent软件对静电除尘器烟道进口处流场进行了数值模拟,在此基础上提出一种新型的能有效均风的电晕线布置方法。结果表明,两相邻(垂直叠放)烟道进口处的电晕线平行放置时,在强电场力作用下产生的高速离子风会阻碍气流的均匀分布;两相邻烟道进口处的电晕线交叉放置时,可以起到明显的均风效果,更有利于除尘器内气流的均匀分布和提高除尘效率。该方法为静电除尘器的改造和设计提供了一种新的思路。The flue gas flow in entrance of electrostatic precipitator was simulated by Fluent software.Base on the simulation result,a new corona wires arrangement method was proposed for better gas flow distribution.The results indicated that when the corona wires in entrance of two adjacent flues arranged in parallel,the high speed ion airflow occurred in strong electric field would hamper the even distribution of flow,while when the corona wires was staggered arranged,it would benefit to the even distribution of gas flow in precipitator and further improve the dust removal efficiency.This result can provide very important guidance to the transformation and the design of electrostatic precipitator.
