濕式電除塵器是一種用來處理含微量粉塵和微顆粒的新除塵設備，主要用來除去含濕氣體中的塵、酸霧、水滴、氣溶膠、臭味、PM2.5等有害物質，是治理大氣粉塵污染的理想設備。

濕式電除塵器通常簡稱WESP，與干式電除塵器的除塵基本原理相同，要經歷荷電、收集和清灰三個階段。

濕式電(dian)(dian)除塵器主(zhu)要有兩種結構形式，一種是(shi)使用耐(nai)(nai)腐蝕導(dao)電(dian)(dian)材料（可以為導(dao)電(dian)(dian)性(xing)能優良的(de)的(de)非金(jin)屬(shu)材料或(huo)具有耐(nai)(nai)腐蝕特性(xing)的(de)金(jin)屬(shu)材料）做(zuo)集塵極，另一種是(shi)用通過(guo)噴水或(huo)溢流水形成導(dao)電(dian)(dian)水膜，利用不導(dao)電(dian)(dian)的(de)非金(jin)屬(shu)材料做(zuo)集塵極。

收塵(chen)原(yuan)理

濕(shi)(shi)式(shi)電(dian)(dian)除塵(chen)(chen)(chen)器(qi)和與干(gan)式(shi)電(dian)(dian)除塵(chen)(chen)(chen)器(qi)的收塵(chen)(chen)(chen)原理(li)相(xiang)同，都是靠高壓電(dian)(dian)暈放電(dian)(dian)使得(de)粉塵(chen)(chen)(chen)荷電(dian)(dian)，荷電(dian)(dian)后的粉塵(chen)(chen)(chen)在電(dian)(dian)場力的作(zuo)用(yong)(yong)下到(dao)(dao)達集(ji)塵(chen)(chen)(chen)板/管。干(gan)式(shi)電(dian)(dian)收塵(chen)(chen)(chen)器(qi)主要處(chu)理(li)含(han)水(shui)(shui)很低(di)的干(gan)氣(qi)體，濕(shi)(shi)式(shi)電(dian)(dian)除塵(chen)(chen)(chen)器(qi)主要處(chu)理(li)含(han)水(shui)(shui)較高乃至飽和的濕(shi)(shi)氣(qi)體。在對集(ji)塵(chen)(chen)(chen)板/管上捕集(ji)到(dao)(dao)的粉塵(chen)(chen)(chen)清(qing)除方(fang)式(shi)上WESP與DESP有較大區別，干(gan)式(shi)電(dian)(dian)除塵(chen)(chen)(chen)器(qi)一般采用(yong)(yong)機械振打或聲波清(qing)灰(hui)等方(fang)式(shi)清(qing)除電(dian)(dian)極(ji)上的積(ji)灰(hui)，而濕(shi)(shi)式(shi)電(dian)(dian)除塵(chen)(chen)(chen)器(qi)則(ze)采用(yong)(yong)定期沖洗的方(fang)式(shi)，使粉塵(chen)(chen)(chen)隨著沖刷(shua)液的流動而清(qing)除。
