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(shi)式電(dian)除(chu)塵(chen)器主要(yao)有兩(liang)種結構(gou)形式，一(yi)種是(shi)使用(yong)耐腐蝕(shi)導電(dian)材(cai)料(liao)（可以為導電(dian)性能優(you)良的的非(fei)金屬材(cai)料(liao)或具(ju)有耐腐蝕(shi)特性的金屬材(cai)料(liao)）做集塵(chen)極(ji)，另一(yi)種是(shi)用(yong)通過噴水(shui)或溢流水(shui)形成(cheng)導電(dian)水(shui)膜，利用(yong)不(bu)導電(dian)的非(fei)金屬材(cai)料(liao)做集塵(chen)極(ji)。

濕式(shi)(shi)電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器(qi)(qi)和與干式(shi)(shi)電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器(qi)(qi)的收塵(chen)(chen)(chen)(chen)原理(li)(li)相同(tong)，都是(shi)靠(kao)高壓電(dian)(dian)(dian)(dian)暈放(fang)電(dian)(dian)(dian)(dian)使(shi)得粉(fen)(fen)塵(chen)(chen)(chen)(chen)荷電(dian)(dian)(dian)(dian)，荷電(dian)(dian)(dian)(dian)后的粉(fen)(fen)塵(chen)(chen)(chen)(chen)在電(dian)(dian)(dian)(dian)場力的作用(yong)下到達集(ji)塵(chen)(chen)(chen)(chen)板/管。干式(shi)(shi)電(dian)(dian)(dian)(dian)收塵(chen)(chen)(chen)(chen)器(qi)(qi)主要處理(li)(li)含(han)水很低的干氣體(ti)，濕式(shi)(shi)電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器(qi)(qi)主要處理(li)(li)含(han)水較高乃(nai)至飽和的濕氣體(ti)。在對集(ji)塵(chen)(chen)(chen)(chen)板/管上(shang)捕集(ji)到的粉(fen)(fen)塵(chen)(chen)(chen)(chen)清(qing)除(chu)方式(shi)(shi)上(shang)WESP與DESP有較大區別，干式(shi)(shi)電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器(qi)(qi)一般采用(yong)機械振(zhen)打或聲波清(qing)灰(hui)等方式(shi)(shi)清(qing)除(chu)電(dian)(dian)(dian)(dian)極上(shang)的積灰(hui)，而(er)濕式(shi)(shi)電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器(qi)(qi)則采用(yong)定期(qi)沖洗的方式(shi)(shi)，使(shi)粉(fen)(fen)塵(chen)(chen)(chen)(chen)隨著沖刷液(ye)的流動而(er)清(qing)除(chu)。
