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)(dian)除塵器主要有(you)兩種結(jie)構形(xing)式，一種是(shi)(shi)使用(yong)耐(nai)腐(fu)蝕導(dao)電(dian)(dian)材料(liao)（可(ke)以(yi)為導(dao)電(dian)(dian)性能優良的(de)(de)(de)的(de)(de)(de)非(fei)金(jin)屬(shu)材料(liao)或(huo)(huo)具有(you)耐(nai)腐(fu)蝕特性的(de)(de)(de)金(jin)屬(shu)材料(liao)）做集(ji)塵極，另(ling)一種是(shi)(shi)用(yong)通過噴水或(huo)(huo)溢流水形(xing)成(cheng)導(dao)電(dian)(dian)水膜，利用(yong)不(bu)導(dao)電(dian)(dian)的(de)(de)(de)非(fei)金(jin)屬(shu)材料(liao)做集(ji)塵極。

濕(shi)式(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器(qi)和(he)與干式(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器(qi)的(de)(de)(de)(de)收塵(chen)(chen)原理相同，都(dou)是靠高(gao)壓(ya)電(dian)(dian)(dian)暈放電(dian)(dian)(dian)使得粉塵(chen)(chen)荷電(dian)(dian)(dian)，荷電(dian)(dian)(dian)后(hou)的(de)(de)(de)(de)粉塵(chen)(chen)在電(dian)(dian)(dian)場力的(de)(de)(de)(de)作用下到(dao)達集塵(chen)(chen)板/管。干式(shi)(shi)電(dian)(dian)(dian)收塵(chen)(chen)器(qi)主(zhu)要處理含(han)水很低的(de)(de)(de)(de)干氣(qi)體(ti)(ti)，濕(shi)式(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器(qi)主(zhu)要處理含(han)水較高(gao)乃至飽和(he)的(de)(de)(de)(de)濕(shi)氣(qi)體(ti)(ti)。在對集塵(chen)(chen)板/管上(shang)捕集到(dao)的(de)(de)(de)(de)粉塵(chen)(chen)清(qing)(qing)除(chu)(chu)方(fang)式(shi)(shi)上(shang)WESP與DESP有較大區(qu)別，干式(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器(qi)一般采(cai)用機械振(zhen)打或聲波清(qing)(qing)灰等方(fang)式(shi)(shi)清(qing)(qing)除(chu)(chu)電(dian)(dian)(dian)極上(shang)的(de)(de)(de)(de)積灰，而濕(shi)式(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器(qi)則采(cai)用定(ding)期沖(chong)洗的(de)(de)(de)(de)方(fang)式(shi)(shi)，使粉塵(chen)(chen)隨著沖(chong)刷(shua)液(ye)的(de)(de)(de)(de)流動(dong)而清(qing)(qing)除(chu)(chu)。
