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(qi)主要有(you)(you)兩種結構(gou)形(xing)式，一種是使(shi)用(yong)耐腐蝕導(dao)電(dian)材料（可以為導(dao)電(dian)性能優良的的非(fei)金(jin)屬材料或(huo)具(ju)有(you)(you)耐腐蝕特(te)性的金(jin)屬材料）做集塵極，另一種是用(yong)通過噴水(shui)或(huo)溢流水(shui)形(xing)成導(dao)電(dian)水(shui)膜，利用(yong)不導(dao)電(dian)的非(fei)金(jin)屬材料做集塵極。

收塵原理

濕式(shi)(shi)(shi)(shi)電(dian)(dian)除(chu)塵(chen)(chen)器(qi)和與(yu)干式(shi)(shi)(shi)(shi)電(dian)(dian)除(chu)塵(chen)(chen)器(qi)的(de)收塵(chen)(chen)原理相同，都是靠(kao)高(gao)(gao)壓電(dian)(dian)暈放電(dian)(dian)使(shi)得粉(fen)(fen)塵(chen)(chen)荷(he)電(dian)(dian)，荷(he)電(dian)(dian)后的(de)粉(fen)(fen)塵(chen)(chen)在(zai)(zai)電(dian)(dian)場(chang)力(li)的(de)作用(yong)下到達集(ji)塵(chen)(chen)板/管(guan)(guan)。干式(shi)(shi)(shi)(shi)電(dian)(dian)收塵(chen)(chen)器(qi)主(zhu)要(yao)(yao)處(chu)理含(han)水(shui)很低(di)的(de)干氣體，濕式(shi)(shi)(shi)(shi)電(dian)(dian)除(chu)塵(chen)(chen)器(qi)主(zhu)要(yao)(yao)處(chu)理含(han)水(shui)較高(gao)(gao)乃至(zhi)飽和的(de)濕氣體。在(zai)(zai)對集(ji)塵(chen)(chen)板/管(guan)(guan)上捕集(ji)到的(de)粉(fen)(fen)塵(chen)(chen)清(qing)除(chu)方(fang)式(shi)(shi)(shi)(shi)上WESP與(yu)DESP有較大區別，干式(shi)(shi)(shi)(shi)電(dian)(dian)除(chu)塵(chen)(chen)器(qi)一般采用(yong)機械振打或(huo)聲波清(qing)灰(hui)等(deng)方(fang)式(shi)(shi)(shi)(shi)清(qing)除(chu)電(dian)(dian)極(ji)上的(de)積灰(hui)，而濕式(shi)(shi)(shi)(shi)電(dian)(dian)除(chu)塵(chen)(chen)器(qi)則采用(yong)定期沖洗(xi)的(de)方(fang)式(shi)(shi)(shi)(shi)，使(shi)粉(fen)(fen)塵(chen)(chen)隨著沖刷(shua)液的(de)流動而清(qing)除(chu)。
