进气烟箱气流特性对气流分布影响的仿真研究
|
摘要
为了更深入地认识进气烟箱气流特性对电除尘器内气流分布均匀性的影响,采用欧拉-拉格朗日多相流模型,应用CFX软件对电除尘器进气烟箱气流特性进行数值模拟计算,获得进气速度和入口粒子浓度对电除尘器内气流分布状况的影响。研究结果可为电除尘器进气烟箱气流特性的选择提供参考。
For a better understanding of influence of flow characteristic of inlet evase on airflow distribution for electrostatic precipitation,we used the Euler- La Grange multiphase flow model and the software of CFX to simulate the flow characteristic of inlet evase to obtain the influence of inlet speed and particle concentration on electrostatic precipitation airflow distribution. The result of this study can provide the useful reference for optimization of flow characteristic of the inlet evase for ESP.
