摘要
为得到阴极阻流板的最佳形状和气流速度
对加装阴极阻流板后电场通道内的气流进行模拟。使用Gambit软件建立计算模型
利用Fluent软件计算得到电除尘器电场通道的气流速度分布。模拟及计算结果表明:加装阴极阻流板
能在电晕线附近形成低流速区
利于阴极收尘;加装管状阻流板时气流分布相对较好;阻流板形状一定时
降低烟气流速利于改善气流分布。
Abstract
In order to obtain the optimal shape and flue gas velocity for cathode spoilers
flow field in electric field channel of the electrostatic precipitator(ESP)equipped with cathode spoiler was simulated.The Gambit software was applied to build the model.The flow gas velocity distribution in electric field channel was obtained by the Fluent software.The results show that:installation of the cathode spoiler can form a low velocity zone in the vicinity of the corona wire
which was conducive for cathode dust collection;the tubular spoiler can make the flue gas velocity be well-distributed;decreasing the flue gas velocity was favorable to improving its distribution when the spoiler shape was constant.
