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)除塵器主要有(you)(you)兩(liang)種結構形(xing)式，一(yi)種是使用(yong)(yong)耐(nai)腐(fu)蝕導(dao)電(dian)材(cai)料(liao)（可以為導(dao)電(dian)性能優良(liang)的的非(fei)金屬(shu)材(cai)料(liao)或(huo)具有(you)(you)耐(nai)腐(fu)蝕特性的金屬(shu)材(cai)料(liao)）做集(ji)塵極(ji)，另一(yi)種是用(yong)(yong)通過噴水或(huo)溢流(liu)水形(xing)成導(dao)電(dian)水膜，利用(yong)(yong)不導(dao)電(dian)的非(fei)金屬(shu)材(cai)料(liao)做集(ji)塵極(ji)。

收塵原理

濕(shi)(shi)式(shi)(shi)(shi)電(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)器和與(yu)干式(shi)(shi)(shi)電(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)器的收(shou)塵(chen)(chen)(chen)(chen)原理相(xiang)同，都是靠高壓電(dian)(dian)暈放電(dian)(dian)使(shi)得(de)粉(fen)塵(chen)(chen)(chen)(chen)荷電(dian)(dian)，荷電(dian)(dian)后的粉(fen)塵(chen)(chen)(chen)(chen)在電(dian)(dian)場力的作用(yong)下到達集塵(chen)(chen)(chen)(chen)板(ban)/管(guan)。干式(shi)(shi)(shi)電(dian)(dian)收(shou)塵(chen)(chen)(chen)(chen)器主要處(chu)理含(han)水很低的干氣體，濕(shi)(shi)式(shi)(shi)(shi)電(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)器主要處(chu)理含(han)水較高乃至飽和的濕(shi)(shi)氣體。在對(dui)集塵(chen)(chen)(chen)(chen)板(ban)/管(guan)上(shang)(shang)捕集到的粉(fen)塵(chen)(chen)(chen)(chen)清除(chu)(chu)(chu)方(fang)(fang)式(shi)(shi)(shi)上(shang)(shang)WESP與(yu)DESP有(you)較大區(qu)別，干式(shi)(shi)(shi)電(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)器一般采用(yong)機械振(zhen)打或聲波清灰等(deng)方(fang)(fang)式(shi)(shi)(shi)清除(chu)(chu)(chu)電(dian)(dian)極上(shang)(shang)的積(ji)灰，而濕(shi)(shi)式(shi)(shi)(shi)電(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)器則采用(yong)定期沖洗的方(fang)(fang)式(shi)(shi)(shi)，使(shi)粉(fen)塵(chen)(chen)(chen)(chen)隨(sui)著沖刷液的流動(dong)而清除(chu)(chu)(chu)。
