| 摘 要： | 烟气增湿对半干半湿法烟气脱硫起着关键作用。本文分析了空气雾化效果优于机械雾化效果;计算了FM10型空气喷嘴雾化粒径可满足给定烟气条件下的蒸发粒径;烟气流中雾羽角度收缩,喷嘴均匀布置于烟道,避免湿壁;烟气增湿后,袋式除尘器需采取良好的保温措施,应选用表面处理的易清灰滤料,圆筒状滤袋。

| Abstract: | Humidification plays a key role in SO_2 removal for semi-dry flue gas desulfurization(FGD).In the article.the analysis is derived that performance of air atomizing is more effective than that of mechanical atomizing.The calculation results show that drop size distribution of FM10 air atomizing nozzle can meet flue gas condition in evaporation.It is deduced that atomizing contrail angle is constrained in the flue gas and laying out of the nozzle in the duct uniformly to avoid drop from wetting wall.Fabric filter is supposed to be nice in heat preservation and easy in ash cleaning.A smooth-surfaced filter material is selected. |
