| 摘 要： | 采用计算流体动力学软件,分别选取了过滤速度和渗透率的4种工况对下进风袋式除尘器的流场进行了数值模拟计算,研究其对气流稳定性的影响。结果表明：随着过滤风速的增大,下进风除尘器内气流分布的不均匀现象反而变得更严重;随着渗透率的增加,气流速度变化就越剧烈,气流的分配也就越不均匀。

| Abstract: | Under inlet bag-type dust collector have accepted extensive application in heat and power engineering.It is very important to study gas-flow field theory for increasing dust removal efficiency and life.Using computational fluid dynamics(CFD) to simulate the flow field distribution within the dust collector,the effect of the filtration velocity and penetration rate to the stability of the airstream have been studied with selecting four conditions and the model had been simulated.The results show that the une... |
