湿式电除尘器采用液体冲刷集尘极表面来进行清灰,可有效收集微细颗粒物(PM2.5粉尘、SO3酸雾、气溶胶)、重金属(Hg、As、Se、Pb、Cr)、有机污染物(多环芳烃、二恶英)等。使用湿式电除尘器后含湿烟气中的烟尘排放可达10mg/m3甚至5mg/m3吴夹客以下,收尘性能与粉尘特性无关,适用于含湿烟气的处理,尤其适用在电厂、钢厂湿法脱硫之后含尘烟气的处理上,但设备投资费用较高,且需与其它除尘设备配套使用,其投资技术经济性和运行成本要从整体进行评价。

 
 

鉴于我国燃煤电厂烟气除尘环保标准日益严格的状况,我公司于2011年2月自主立项研发湿式电除尘(雾)技术,旨在控制脱硫塔后湿烟气携带雾滴及粉尘,使排入大气的烟尘实现达标排放,PM2.5得到有效控制。目前,该技术经过进行工程示范,取得圆满成功PM2.5的排放达到0.95毫克/立方米

电除雾器,湿式电除尘(雾)器WESP技术原理

湿式电除尘器与干式电除尘器工作原理相同,都是向电场空间输送直流负高压,通过空间气体电离,烟气中粉尘颗粒和雾滴颗粒荷电后在电场力的作用下,移动到收尘极板(集电极),从而被收集在收尘极表面。干式电除尘器利用振打清灰方式将收集到的粉尘震落到灰斗中,而湿式电除尘器则是通过收集烟气中的雾滴颗粒,在收尘极表面形成溢流而将粉尘冲洗到灰斗(水灰斗)中。

湿式电除尘器与干式电除尘器zui大的不同,在于烟气工质的差异,干式电除尘器烟气为干烟气,烟气温度较高,烟气中基本不含雾滴。而湿式电除尘器为湿饱和烟气,烟气温度较低,烟气中含有大量的雾滴。

湿式电除尘器通常设置在湿法脱硫装置后,脱硫后饱和烟气中携带大量水滴,在通过高压电场时被捕获,能够减小石膏雨形成的几率。同时对于收集微细颗粒物PM2.5、酸雾等有较好的效果,烟尘排放浓度可以达到≤10毫克/立方米。




湿式电除尘器,阳极板采用新型防腐材质,不需要连续喷入碱性水,系统结构简单,并实现了五项技术创新:

1.采用新型的耐腐蚀复合材料作为收尘极板,模块化结构、蜂窝布置,能有效利用空间、流场分布均匀。耐腐蚀,放电强力稳定,使设备电压、电流处于较高的参数,从而保证较好的除尘效果。

2.采用新型耐腐蚀复合材料使电除尘(雾)器结构布置灵活,能够适应目前复杂的改造场地,可单独布置于脱硫塔出口净气烟道处,也可布置于脱硫塔塔顶,或者单独布置于电厂场地条件允许的空地。

3.运行时不需要连续喷入碱性水,依靠电场区收集烟气中雾滴,在收尘管束内形成溢流,达到自流清灰的目的。

4.高压电源采用横流源和高效火花控制装置,能够有效避免闪落拉弧现象,保证电场稳定运行。

5.湿式电除尘器是当前先进的PM2.5控制技术之一,能达到如下性能指标:
吴夹客示范项目的成功,表明湿式电除尘器技术已经具备了在大型火力发电厂推广应用的条件,为满足当前和今后日益严格的燃煤电厂粉尘排放要求提供了有效的解决方案,为燃煤机组达到燃气机组的粉尘排放水平提供了一个可行的技术路线。湿式电除尘技术是现阶段湿法脱硫、湿烟气严格控制的有效技术,PM2.5控制效果良好,具备向重点区域、除尘及脱硫系统改造达标难度大的电厂进行推广的条件。
