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)(dian)除塵器主要有兩種(zhong)結構形式，一(yi)種(zhong)是使用耐(nai)腐蝕(shi)導電(dian)(dian)材(cai)(cai)料(liao)(liao)(liao)(liao)（可以為導電(dian)(dian)性能優(you)良的的非金屬(shu)(shu)材(cai)(cai)料(liao)(liao)(liao)(liao)或具(ju)有耐(nai)腐蝕(shi)特性的金屬(shu)(shu)材(cai)(cai)料(liao)(liao)(liao)(liao)）做集塵極(ji)，另(ling)一(yi)種(zhong)是用通過噴(pen)水(shui)或溢流水(shui)形成導電(dian)(dian)水(shui)膜，利用不導電(dian)(dian)的非金屬(shu)(shu)材(cai)(cai)料(liao)(liao)(liao)(liao)做集塵極(ji)。

濕(shi)式(shi)(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器和(he)與(yu)(yu)干式(shi)(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器的(de)(de)收(shou)塵(chen)(chen)原理相同，都是(shi)靠(kao)高(gao)壓電(dian)(dian)(dian)暈放電(dian)(dian)(dian)使得粉(fen)塵(chen)(chen)荷(he)電(dian)(dian)(dian)，荷(he)電(dian)(dian)(dian)后的(de)(de)粉(fen)塵(chen)(chen)在電(dian)(dian)(dian)場力的(de)(de)作用下到(dao)達集塵(chen)(chen)板(ban)(ban)/管(guan)(guan)。干式(shi)(shi)(shi)電(dian)(dian)(dian)收(shou)塵(chen)(chen)器主要處理含水(shui)很低的(de)(de)干氣體(ti)，濕(shi)式(shi)(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器主要處理含水(shui)較高(gao)乃至飽(bao)和(he)的(de)(de)濕(shi)氣體(ti)。在對集塵(chen)(chen)板(ban)(ban)/管(guan)(guan)上捕(bu)集到(dao)的(de)(de)粉(fen)塵(chen)(chen)清(qing)除(chu)(chu)方(fang)式(shi)(shi)(shi)上WESP與(yu)(yu)DESP有較大區別，干式(shi)(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器一般采(cai)用機械(xie)振(zhen)打或聲波清(qing)灰等方(fang)式(shi)(shi)(shi)清(qing)除(chu)(chu)電(dian)(dian)(dian)極上的(de)(de)積灰，而濕(shi)式(shi)(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)器則(ze)采(cai)用定期沖(chong)洗的(de)(de)方(fang)式(shi)(shi)(shi)，使粉(fen)塵(chen)(chen)隨著沖(chong)刷(shua)液的(de)(de)流動而清(qing)除(chu)(chu)。
