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)除塵器主要有兩種(zhong)結構形式(shi)，一種(zhong)是使用(yong)耐腐蝕(shi)導電(dian)材(cai)料（可(ke)以(yi)為(wei)導電(dian)性(xing)能優良(liang)的(de)的(de)非(fei)(fei)金(jin)(jin)屬(shu)材(cai)料或具有耐腐蝕(shi)特性(xing)的(de)金(jin)(jin)屬(shu)材(cai)料）做集塵極(ji)(ji)，另一種(zhong)是用(yong)通過噴(pen)水(shui)或溢流水(shui)形成導電(dian)水(shui)膜，利用(yong)不導電(dian)的(de)非(fei)(fei)金(jin)(jin)屬(shu)材(cai)料做集塵極(ji)(ji)。

濕(shi)式(shi)(shi)(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)器(qi)(qi)和與干(gan)(gan)式(shi)(shi)(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)器(qi)(qi)的(de)(de)收塵(chen)原理相同，都是靠(kao)高壓(ya)電(dian)(dian)(dian)暈放電(dian)(dian)(dian)使得粉(fen)塵(chen)荷(he)電(dian)(dian)(dian)，荷(he)電(dian)(dian)(dian)后的(de)(de)粉(fen)塵(chen)在電(dian)(dian)(dian)場力的(de)(de)作用下(xia)到達集塵(chen)板/管。干(gan)(gan)式(shi)(shi)(shi)(shi)電(dian)(dian)(dian)收塵(chen)器(qi)(qi)主(zhu)要處理含(han)水(shui)很低的(de)(de)干(gan)(gan)氣體(ti)(ti)，濕(shi)式(shi)(shi)(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)器(qi)(qi)主(zhu)要處理含(han)水(shui)較高乃(nai)至飽和的(de)(de)濕(shi)氣體(ti)(ti)。在對集塵(chen)板/管上捕集到的(de)(de)粉(fen)塵(chen)清(qing)(qing)除(chu)(chu)方(fang)(fang)(fang)式(shi)(shi)(shi)(shi)上WESP與DESP有較大(da)區別，干(gan)(gan)式(shi)(shi)(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)器(qi)(qi)一般采用機械振打或聲(sheng)波清(qing)(qing)灰等方(fang)(fang)(fang)式(shi)(shi)(shi)(shi)清(qing)(qing)除(chu)(chu)電(dian)(dian)(dian)極上的(de)(de)積(ji)灰，而濕(shi)式(shi)(shi)(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)器(qi)(qi)則采用定期沖(chong)洗(xi)的(de)(de)方(fang)(fang)(fang)式(shi)(shi)(shi)(shi)，使粉(fen)塵(chen)隨著沖(chong)刷液的(de)(de)流動而清(qing)(qing)除(chu)(chu)。
