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(chen)器主要有兩種(zhong)結構形(xing)式，一種(zhong)是(shi)使(shi)用(yong)(yong)耐腐(fu)蝕導(dao)電(dian)材料(liao)(liao)（可以(yi)為導(dao)電(dian)性能優良(liang)的(de)的(de)非(fei)(fei)金屬材料(liao)(liao)或具(ju)有耐腐(fu)蝕特性的(de)金屬材料(liao)(liao)）做集塵(chen)極，另(ling)一種(zhong)是(shi)用(yong)(yong)通過噴水或溢流水形(xing)成導(dao)電(dian)水膜，利(li)用(yong)(yong)不導(dao)電(dian)的(de)非(fei)(fei)金屬材料(liao)(liao)做集塵(chen)極。

濕式(shi)電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)器(qi)和與干式(shi)電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)器(qi)的(de)收塵(chen)(chen)原理相(xiang)同，都是靠高壓電(dian)(dian)(dian)暈放電(dian)(dian)(dian)使得粉(fen)(fen)塵(chen)(chen)荷電(dian)(dian)(dian)，荷電(dian)(dian)(dian)后的(de)粉(fen)(fen)塵(chen)(chen)在電(dian)(dian)(dian)場力的(de)作用下到達集(ji)(ji)塵(chen)(chen)板(ban)/管(guan)。干式(shi)電(dian)(dian)(dian)收塵(chen)(chen)器(qi)主(zhu)要(yao)處理含水很低的(de)干氣(qi)(qi)體，濕式(shi)電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)器(qi)主(zhu)要(yao)處理含水較(jiao)高乃(nai)至飽(bao)和的(de)濕氣(qi)(qi)體。在對集(ji)(ji)塵(chen)(chen)板(ban)/管(guan)上捕集(ji)(ji)到的(de)粉(fen)(fen)塵(chen)(chen)清(qing)除(chu)(chu)(chu)方式(shi)上WESP與DESP有較(jiao)大(da)區別，干式(shi)電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)器(qi)一般采(cai)用機械(xie)振(zhen)打或聲波清(qing)灰等方式(shi)清(qing)除(chu)(chu)(chu)電(dian)(dian)(dian)極上的(de)積灰，而濕式(shi)電(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)器(qi)則采(cai)用定期(qi)沖洗的(de)方式(shi)，使粉(fen)(fen)塵(chen)(chen)隨著沖刷液的(de)流(liu)動而清(qing)除(chu)(chu)(chu)。
