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(chen)器主要有(you)(you)兩種(zhong)(zhong)結構(gou)形式，一種(zhong)(zhong)是使用耐腐(fu)蝕導電材料（可以為導電性(xing)能(neng)優良的的非(fei)金屬(shu)(shu)材料或具有(you)(you)耐腐(fu)蝕特性(xing)的金屬(shu)(shu)材料）做集塵(chen)極，另一種(zhong)(zhong)是用通過噴水(shui)或溢流水(shui)形成導電水(shui)膜，利用不導電的非(fei)金屬(shu)(shu)材料做集塵(chen)極。

收塵原理(li)

濕式(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)(qi)(qi)和與干式(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)(qi)(qi)的(de)(de)(de)收塵(chen)(chen)原理(li)相同，都(dou)是靠(kao)高(gao)壓電(dian)(dian)(dian)暈放電(dian)(dian)(dian)使(shi)得(de)粉(fen)塵(chen)(chen)荷(he)電(dian)(dian)(dian)，荷(he)電(dian)(dian)(dian)后的(de)(de)(de)粉(fen)塵(chen)(chen)在電(dian)(dian)(dian)場(chang)力的(de)(de)(de)作用(yong)下到達集(ji)塵(chen)(chen)板/管(guan)。干式(shi)電(dian)(dian)(dian)收塵(chen)(chen)器(qi)(qi)(qi)主要處(chu)理(li)含水很(hen)低的(de)(de)(de)干氣體，濕式(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)(qi)(qi)主要處(chu)理(li)含水較高(gao)乃(nai)至飽和的(de)(de)(de)濕氣體。在對集(ji)塵(chen)(chen)板/管(guan)上捕集(ji)到的(de)(de)(de)粉(fen)塵(chen)(chen)清(qing)除(chu)方式(shi)上WESP與DESP有(you)較大區別，干式(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)(qi)(qi)一般采用(yong)機械(xie)振(zhen)打或聲波清(qing)灰等方式(shi)清(qing)除(chu)電(dian)(dian)(dian)極上的(de)(de)(de)積灰，而濕式(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)器(qi)(qi)(qi)則采用(yong)定期(qi)沖(chong)洗(xi)的(de)(de)(de)方式(shi)，使(shi)粉(fen)塵(chen)(chen)隨著沖(chong)刷(shua)液的(de)(de)(de)流動而清(qing)除(chu)。
