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)電除塵器主要有兩(liang)種(zhong)結構形式(shi)，一(yi)種(zhong)是(shi)使(shi)用(yong)耐腐蝕(shi)導(dao)電材(cai)料(liao)（可以為導(dao)電性能(neng)優良(liang)的(de)(de)的(de)(de)非(fei)金(jin)屬材(cai)料(liao)或具有耐腐蝕(shi)特(te)性的(de)(de)金(jin)屬材(cai)料(liao)）做(zuo)集(ji)塵極，另一(yi)種(zhong)是(shi)用(yong)通過(guo)噴(pen)水或溢流水形成導(dao)電水膜(mo)，利用(yong)不導(dao)電的(de)(de)非(fei)金(jin)屬材(cai)料(liao)做(zuo)集(ji)塵極。

收(shou)塵原理

濕式(shi)(shi)電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器和與干式(shi)(shi)電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器的(de)收塵(chen)(chen)原理相同，都是靠(kao)高壓(ya)電(dian)(dian)(dian)(dian)暈放電(dian)(dian)(dian)(dian)使得粉(fen)(fen)塵(chen)(chen)荷電(dian)(dian)(dian)(dian)，荷電(dian)(dian)(dian)(dian)后的(de)粉(fen)(fen)塵(chen)(chen)在電(dian)(dian)(dian)(dian)場力的(de)作用(yong)(yong)下到達集(ji)塵(chen)(chen)板(ban)/管。干式(shi)(shi)電(dian)(dian)(dian)(dian)收塵(chen)(chen)器主要處理含水(shui)(shui)很低(di)的(de)干氣(qi)體(ti)(ti)，濕式(shi)(shi)電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器主要處理含水(shui)(shui)較高乃(nai)至飽和的(de)濕氣(qi)體(ti)(ti)。在對集(ji)塵(chen)(chen)板(ban)/管上(shang)(shang)捕集(ji)到的(de)粉(fen)(fen)塵(chen)(chen)清(qing)(qing)除(chu)方(fang)(fang)式(shi)(shi)上(shang)(shang)WESP與DESP有(you)較大區別，干式(shi)(shi)電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器一般采(cai)用(yong)(yong)機械振打(da)或聲波清(qing)(qing)灰等方(fang)(fang)式(shi)(shi)清(qing)(qing)除(chu)電(dian)(dian)(dian)(dian)極(ji)上(shang)(shang)的(de)積(ji)灰，而濕式(shi)(shi)電(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)器則采(cai)用(yong)(yong)定期沖洗的(de)方(fang)(fang)式(shi)(shi)，使粉(fen)(fen)塵(chen)(chen)隨著沖刷液(ye)的(de)流動(dong)而清(qing)(qing)除(chu)。
