Abstract

大型串联一体式电袋复合除尘器气流分布是影响除尘效率的因素。应用数值模拟方法计算300 MW机组电袋复合除尘器内部流场状态,依据除尘器内部全流场、滤袋迎风面气流速度和滤袋单元流量分配的要求,对比3种方案后最终确定采用在电袋复合除尘器中间设置多孔气流分布板,末端灰斗两侧沿宽度方向设置挡风板的方案。该方案应用后的试验结果与数值模拟结果基本一致,可获得良好的气流流场分布。

对比3种方案后最终确定采用在电袋复合除尘器中间设置多孔气流分布板

Abstract

The gas flow distribution in large tandem integrated electrostatic bag precipitator(EBP) was an important factor which affects the equipment performance.By using numerical simulation method

the internal gas flow distribution in EBP of a 300 MW unit has been calculated.According to the requirements for the internal whole flow field in the precipitator

for gas flow speed at the windward side of the filtering bag

and for flow rate distribution in a filtering bag unit

after comparison of three schemes

a scheme of installing porous gas flow distributing plate in EBP

and installing baffle plate along direction of width at two sides of final-end ash hopper has been finally determined.The results of application test is basically conformed with results of numerical simulation

satisfying the requirements of gas flow field distribution.
