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)除塵(chen)(chen)器主要有(you)兩種結構形式(shi)，一種是(shi)使用(yong)耐腐蝕(shi)(shi)導(dao)電(dian)材(cai)料（可以為(wei)導(dao)電(dian)性(xing)能優良的的非金屬材(cai)料或(huo)具有(you)耐腐蝕(shi)(shi)特性(xing)的金屬材(cai)料）做集(ji)(ji)塵(chen)(chen)極，另一種是(shi)用(yong)通(tong)過(guo)噴水(shui)或(huo)溢流(liu)水(shui)形成導(dao)電(dian)水(shui)膜，利用(yong)不導(dao)電(dian)的非金屬材(cai)料做集(ji)(ji)塵(chen)(chen)極。

收塵原理(li)

濕式(shi)(shi)電(dian)(dian)(dian)除塵(chen)(chen)器和與干式(shi)(shi)電(dian)(dian)(dian)除塵(chen)(chen)器的(de)(de)收塵(chen)(chen)原理(li)相同，都(dou)是靠高(gao)壓(ya)電(dian)(dian)(dian)暈(yun)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)(de)粉(fen)塵(chen)(chen)在電(dian)(dian)(dian)場力的(de)(de)作用(yong)下到達集(ji)塵(chen)(chen)板/管。干式(shi)(shi)電(dian)(dian)(dian)收塵(chen)(chen)器主(zhu)要處(chu)(chu)理(li)含(han)水很(hen)低的(de)(de)干氣(qi)(qi)體(ti)，濕式(shi)(shi)電(dian)(dian)(dian)除塵(chen)(chen)器主(zhu)要處(chu)(chu)理(li)含(han)水較高(gao)乃至飽(bao)和的(de)(de)濕氣(qi)(qi)體(ti)。在對集(ji)塵(chen)(chen)板/管上捕集(ji)到的(de)(de)粉(fen)塵(chen)(chen)清(qing)除方(fang)式(shi)(shi)上WESP與DESP有較大(da)區(qu)別(bie)，干式(shi)(shi)電(dian)(dian)(dian)除塵(chen)(chen)器一般采用(yong)機械振打(da)或聲波清(qing)灰等方(fang)式(shi)(shi)清(qing)除電(dian)(dian)(dian)極上的(de)(de)積灰，而濕式(shi)(shi)電(dian)(dian)(dian)除塵(chen)(chen)器則采用(yong)定期(qi)沖洗的(de)(de)方(fang)式(shi)(shi)，使粉(fen)塵(chen)(chen)隨著(zhu)沖刷液的(de)(de)流動而清(qing)除。
