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(dian)除塵器主(zhu)要有(you)兩種(zhong)結構形式，一種(zhong)是使(shi)用(yong)耐腐蝕導(dao)電(dian)材料（可以為(wei)導(dao)電(dian)性能(neng)優良的的非金屬材料或具有(you)耐腐蝕特性的金屬材料）做集(ji)塵極，另一種(zhong)是用(yong)通過噴水(shui)(shui)或溢流水(shui)(shui)形成導(dao)電(dian)水(shui)(shui)膜，利用(yong)不導(dao)電(dian)的非金屬材料做集(ji)塵極。

濕(shi)式(shi)(shi)(shi)電(dian)(dian)除(chu)(chu)(chu)塵器(qi)和(he)與干式(shi)(shi)(shi)電(dian)(dian)除(chu)(chu)(chu)塵器(qi)的(de)(de)收塵原理相同(tong)，都是靠高(gao)壓(ya)電(dian)(dian)暈放電(dian)(dian)使得粉(fen)塵荷電(dian)(dian)，荷電(dian)(dian)后的(de)(de)粉(fen)塵在電(dian)(dian)場(chang)力的(de)(de)作用下(xia)到(dao)(dao)達集塵板(ban)(ban)/管(guan)。干式(shi)(shi)(shi)電(dian)(dian)收塵器(qi)主要處理含水很低的(de)(de)干氣(qi)體，濕(shi)式(shi)(shi)(shi)電(dian)(dian)除(chu)(chu)(chu)塵器(qi)主要處理含水較高(gao)乃至飽和(he)的(de)(de)濕(shi)氣(qi)體。在對(dui)集塵板(ban)(ban)/管(guan)上(shang)(shang)捕集到(dao)(dao)的(de)(de)粉(fen)塵清除(chu)(chu)(chu)方(fang)(fang)式(shi)(shi)(shi)上(shang)(shang)WESP與DESP有較大區別，干式(shi)(shi)(shi)電(dian)(dian)除(chu)(chu)(chu)塵器(qi)一般采用機械振打或(huo)聲波清灰(hui)等方(fang)(fang)式(shi)(shi)(shi)清除(chu)(chu)(chu)電(dian)(dian)極上(shang)(shang)的(de)(de)積灰(hui)，而(er)濕(shi)式(shi)(shi)(shi)電(dian)(dian)除(chu)(chu)(chu)塵器(qi)則采用定期(qi)沖(chong)洗(xi)的(de)(de)方(fang)(fang)式(shi)(shi)(shi)，使粉(fen)塵隨(sui)著沖(chong)刷液的(de)(de)流(liu)動而(er)清除(chu)(chu)(chu)。
