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(zhu)要(yao)有(you)兩種結構形式，一種是使用(yong)(yong)耐腐蝕導(dao)(dao)(dao)電材料(liao)（可(ke)以為導(dao)(dao)(dao)電性能優良的(de)的(de)非金(jin)(jin)屬(shu)材料(liao)或具(ju)有(you)耐腐蝕特性的(de)金(jin)(jin)屬(shu)材料(liao)）做集塵(chen)極，另(ling)一種是用(yong)(yong)通過噴水(shui)或溢流水(shui)形成導(dao)(dao)(dao)電水(shui)膜，利用(yong)(yong)不導(dao)(dao)(dao)電的(de)非金(jin)(jin)屬(shu)材料(liao)做集塵(chen)極。

收塵原理

濕(shi)式(shi)(shi)電(dian)(dian)(dian)(dian)除(chu)塵(chen)器(qi)和與干式(shi)(shi)電(dian)(dian)(dian)(dian)除(chu)塵(chen)器(qi)的(de)(de)(de)收塵(chen)原理相(xiang)同(tong)，都是靠高壓電(dian)(dian)(dian)(dian)暈放電(dian)(dian)(dian)(dian)使得粉(fen)塵(chen)荷電(dian)(dian)(dian)(dian)，荷電(dian)(dian)(dian)(dian)后的(de)(de)(de)粉(fen)塵(chen)在電(dian)(dian)(dian)(dian)場力的(de)(de)(de)作用(yong)下到達集(ji)塵(chen)板/管。干式(shi)(shi)電(dian)(dian)(dian)(dian)收塵(chen)器(qi)主要處理含(han)水很低的(de)(de)(de)干氣(qi)體，濕(shi)式(shi)(shi)電(dian)(dian)(dian)(dian)除(chu)塵(chen)器(qi)主要處理含(han)水較高乃至飽和的(de)(de)(de)濕(shi)氣(qi)體。在對集(ji)塵(chen)板/管上(shang)捕集(ji)到的(de)(de)(de)粉(fen)塵(chen)清(qing)(qing)除(chu)方式(shi)(shi)上(shang)WESP與DESP有較大區別(bie)，干式(shi)(shi)電(dian)(dian)(dian)(dian)除(chu)塵(chen)器(qi)一般采(cai)用(yong)機械振打(da)或聲波清(qing)(qing)灰(hui)等方式(shi)(shi)清(qing)(qing)除(chu)電(dian)(dian)(dian)(dian)極上(shang)的(de)(de)(de)積灰(hui)，而濕(shi)式(shi)(shi)電(dian)(dian)(dian)(dian)除(chu)塵(chen)器(qi)則采(cai)用(yong)定期沖(chong)洗的(de)(de)(de)方式(shi)(shi)，使粉(fen)塵(chen)隨(sui)著沖(chong)刷(shua)液的(de)(de)(de)流(liu)動而清(qing)(qing)除(chu)。
