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。

濕式電除塵器主要有兩種(zhong)(zhong)結構形式，一(yi)種(zhong)(zhong)是使(shi)用耐(nai)腐蝕(shi)導電材料(liao)（可以(yi)為導電性(xing)能優良(liang)的的非(fei)金(jin)屬(shu)(shu)材料(liao)或(huo)具有耐(nai)腐蝕(shi)特性(xing)的金(jin)屬(shu)(shu)材料(liao)）做集塵極(ji)，另一(yi)種(zhong)(zhong)是用通過噴水或(huo)溢流水形成導電水膜(mo)，利用不導電的非(fei)金(jin)屬(shu)(shu)材料(liao)做集塵極(ji)。

濕式電(dian)除塵(chen)(chen)(chen)(chen)(chen)(chen)器(qi)(qi)和與(yu)干(gan)式電(dian)除塵(chen)(chen)(chen)(chen)(chen)(chen)器(qi)(qi)的收塵(chen)(chen)(chen)(chen)(chen)(chen)原理相(xiang)同，都是靠(kao)高壓(ya)電(dian)暈放電(dian)使(shi)得粉(fen)(fen)(fen)塵(chen)(chen)(chen)(chen)(chen)(chen)荷(he)電(dian)，荷(he)電(dian)后的粉(fen)(fen)(fen)塵(chen)(chen)(chen)(chen)(chen)(chen)在(zai)電(dian)場(chang)力的作用下到達集(ji)塵(chen)(chen)(chen)(chen)(chen)(chen)板/管(guan)。干(gan)式電(dian)收塵(chen)(chen)(chen)(chen)(chen)(chen)器(qi)(qi)主(zhu)要處(chu)理含(han)水(shui)(shui)很(hen)低的干(gan)氣體，濕式電(dian)除塵(chen)(chen)(chen)(chen)(chen)(chen)器(qi)(qi)主(zhu)要處(chu)理含(han)水(shui)(shui)較高乃至飽(bao)和的濕氣體。在(zai)對(dui)集(ji)塵(chen)(chen)(chen)(chen)(chen)(chen)板/管(guan)上捕集(ji)到的粉(fen)(fen)(fen)塵(chen)(chen)(chen)(chen)(chen)(chen)清(qing)除方式上WESP與(yu)DESP有較大(da)區別，干(gan)式電(dian)除塵(chen)(chen)(chen)(chen)(chen)(chen)器(qi)(qi)一般采(cai)用機械振打或聲(sheng)波清(qing)灰(hui)等方式清(qing)除電(dian)極上的積灰(hui)，而濕式電(dian)除塵(chen)(chen)(chen)(chen)(chen)(chen)器(qi)(qi)則采(cai)用定期沖(chong)洗的方式，使(shi)粉(fen)(fen)(fen)塵(chen)(chen)(chen)(chen)(chen)(chen)隨著(zhu)沖(chong)刷液(ye)的流(liu)動而清(qing)除。
