电袋复合除尘器气流分布的数值模拟和优化
Numerical simulation and optimization of gas flow distribution on electrostatic-fabric integrated precipitator
摘要
Abstract
Flow field in the electrostatic-fabric integrated precipitator (EFIP) of a 150 MW unit was investigated by numerical simulation,and the optimized design was obtained.A comparison of the numerical simulation results reveals that installing guide plates in the inlet pipe,adjusting the guide vanes of the perforated plates and the porosity of the third perforated plate in the inlet nozzle,and adding a perforated plate in the conjunction of the electric and bags zone have a significant positive effect on the flow field.After optimizing,the flow distribution in the inlet of the electric field,the gas velocity at the windward side of the filtering bags,the gas flow devi ation of the six bag units,and the relative root mean square value of each bag's flow in per bag unit satisfy the design requirements for flow field.This study can provide a reference for designing the electrostatic-fabric integrated precipitator.关键词
