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(shi)電(dian)(dian)除塵器(qi)主要有兩(liang)種(zhong)結構形式(shi)，一種(zhong)是使用耐腐蝕(shi)導電(dian)(dian)材(cai)料(liao)（可以為導電(dian)(dian)性能優良(liang)的的非金(jin)(jin)屬(shu)材(cai)料(liao)或具有耐腐蝕(shi)特(te)性的金(jin)(jin)屬(shu)材(cai)料(liao)）做集塵極，另一種(zhong)是用通過噴(pen)水或溢(yi)流(liu)水形成導電(dian)(dian)水膜，利用不(bu)導電(dian)(dian)的非金(jin)(jin)屬(shu)材(cai)料(liao)做集塵極。

濕(shi)式(shi)(shi)電(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)器和與干式(shi)(shi)電(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)器的收塵(chen)(chen)原(yuan)理(li)相(xiang)同，都(dou)是靠高(gao)壓(ya)電(dian)(dian)暈放電(dian)(dian)使得粉(fen)塵(chen)(chen)荷電(dian)(dian)，荷電(dian)(dian)后的粉(fen)塵(chen)(chen)在電(dian)(dian)場力的作用(yong)(yong)下(xia)到達(da)集(ji)塵(chen)(chen)板/管。干式(shi)(shi)電(dian)(dian)收塵(chen)(chen)器主要(yao)處理(li)含水很低的干氣體(ti)(ti)，濕(shi)式(shi)(shi)電(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)器主要(yao)處理(li)含水較高(gao)乃至飽和的濕(shi)氣體(ti)(ti)。在對集(ji)塵(chen)(chen)板/管上捕集(ji)到的粉(fen)塵(chen)(chen)清除(chu)(chu)(chu)方式(shi)(shi)上WESP與DESP有較大區別，干式(shi)(shi)電(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)器一般采用(yong)(yong)機械振打或聲波(bo)清灰(hui)等方式(shi)(shi)清除(chu)(chu)(chu)電(dian)(dian)極上的積灰(hui)，而濕(shi)式(shi)(shi)電(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)器則(ze)采用(yong)(yong)定期沖(chong)(chong)洗的方式(shi)(shi)，使粉(fen)塵(chen)(chen)隨(sui)著沖(chong)(chong)刷(shua)液(ye)的流動而清除(chu)(chu)(chu)。
