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(shi)式(shi)電(dian)(dian)除塵器主(zhu)要有(you)兩種(zhong)結(jie)構形式(shi)，一種(zhong)是使用耐腐蝕導(dao)電(dian)(dian)材(cai)料(liao)（可以為導(dao)電(dian)(dian)性能優(you)良的(de)的(de)非金(jin)屬材(cai)料(liao)或(huo)具有(you)耐腐蝕特(te)性的(de)金(jin)屬材(cai)料(liao)）做集塵極，另一種(zhong)是用通過噴(pen)水(shui)或(huo)溢流水(shui)形成導(dao)電(dian)(dian)水(shui)膜，利用不導(dao)電(dian)(dian)的(de)非金(jin)屬材(cai)料(liao)做集塵極。

濕式(shi)(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)器(qi)(qi)和與干(gan)(gan)(gan)式(shi)(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)器(qi)(qi)的(de)收塵(chen)(chen)(chen)原理相同，都是靠高(gao)壓(ya)電(dian)(dian)(dian)暈(yun)放電(dian)(dian)(dian)使得粉(fen)塵(chen)(chen)(chen)荷電(dian)(dian)(dian)，荷電(dian)(dian)(dian)后的(de)粉(fen)塵(chen)(chen)(chen)在電(dian)(dian)(dian)場力的(de)作(zuo)用下到達集塵(chen)(chen)(chen)板/管(guan)。干(gan)(gan)(gan)式(shi)(shi)(shi)電(dian)(dian)(dian)收塵(chen)(chen)(chen)器(qi)(qi)主(zhu)要(yao)處(chu)理含(han)水很低的(de)干(gan)(gan)(gan)氣體(ti)，濕式(shi)(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)器(qi)(qi)主(zhu)要(yao)處(chu)理含(han)水較高(gao)乃至飽和的(de)濕氣體(ti)。在對集塵(chen)(chen)(chen)板/管(guan)上捕集到的(de)粉(fen)塵(chen)(chen)(chen)清(qing)除(chu)(chu)(chu)方式(shi)(shi)(shi)上WESP與DESP有較大區別，干(gan)(gan)(gan)式(shi)(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)器(qi)(qi)一般采用機(ji)械(xie)振打或聲波清(qing)灰等方式(shi)(shi)(shi)清(qing)除(chu)(chu)(chu)電(dian)(dian)(dian)極(ji)上的(de)積灰，而濕式(shi)(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)器(qi)(qi)則(ze)采用定期(qi)沖洗的(de)方式(shi)(shi)(shi)，使粉(fen)塵(chen)(chen)(chen)隨著沖刷液(ye)的(de)流動而清(qing)除(chu)(chu)(chu)。
