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(shi)電(dian)(dian)除塵器主要有(you)兩種(zhong)結構(gou)形式(shi)，一(yi)種(zhong)是(shi)(shi)使用耐(nai)腐蝕(shi)導電(dian)(dian)材(cai)(cai)料(liao)(liao)（可以為導電(dian)(dian)性(xing)能優良(liang)的的非金(jin)屬材(cai)(cai)料(liao)(liao)或具有(you)耐(nai)腐蝕(shi)特性(xing)的金(jin)屬材(cai)(cai)料(liao)(liao)）做(zuo)集塵極(ji)，另一(yi)種(zhong)是(shi)(shi)用通過噴水(shui)或溢流水(shui)形成導電(dian)(dian)水(shui)膜，利用不導電(dian)(dian)的非金(jin)屬材(cai)(cai)料(liao)(liao)做(zuo)集塵極(ji)。

濕式(shi)(shi)(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)器和(he)與干式(shi)(shi)(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)器的(de)收塵(chen)(chen)原理相同，都(dou)是靠高壓電(dian)(dian)(dian)暈放電(dian)(dian)(dian)使得(de)粉(fen)塵(chen)(chen)荷電(dian)(dian)(dian)，荷電(dian)(dian)(dian)后的(de)粉(fen)塵(chen)(chen)在(zai)電(dian)(dian)(dian)場力的(de)作(zuo)用下到達集塵(chen)(chen)板(ban)(ban)/管。干式(shi)(shi)(shi)電(dian)(dian)(dian)收塵(chen)(chen)器主要(yao)處理含水很低(di)的(de)干氣(qi)體，濕式(shi)(shi)(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)器主要(yao)處理含水較(jiao)高乃至飽和(he)的(de)濕氣(qi)體。在(zai)對集塵(chen)(chen)板(ban)(ban)/管上捕集到的(de)粉(fen)塵(chen)(chen)清(qing)(qing)除(chu)方式(shi)(shi)(shi)上WESP與DESP有較(jiao)大區(qu)別，干式(shi)(shi)(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)器一(yi)般(ban)采用機械振(zhen)打(da)或(huo)聲波清(qing)(qing)灰(hui)(hui)等(deng)方式(shi)(shi)(shi)清(qing)(qing)除(chu)電(dian)(dian)(dian)極(ji)上的(de)積灰(hui)(hui)，而(er)濕式(shi)(shi)(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)器則采用定期(qi)沖洗的(de)方式(shi)(shi)(shi)，使粉(fen)塵(chen)(chen)隨著沖刷液的(de)流動而(er)清(qing)(qing)除(chu)。
