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)(dian)(dian)除(chu)塵器主要有兩(liang)種結構(gou)形(xing)式(shi)，一(yi)種是(shi)使用耐腐(fu)蝕導(dao)電(dian)(dian)(dian)材(cai)料（可以為導(dao)電(dian)(dian)(dian)性能優良的的非金(jin)屬(shu)材(cai)料或(huo)具有耐腐(fu)蝕特性的金(jin)屬(shu)材(cai)料）做集(ji)塵極(ji)，另一(yi)種是(shi)用通(tong)過噴水(shui)或(huo)溢流水(shui)形(xing)成導(dao)電(dian)(dian)(dian)水(shui)膜，利用不導(dao)電(dian)(dian)(dian)的非金(jin)屬(shu)材(cai)料做集(ji)塵極(ji)。

濕式(shi)(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)器(qi)(qi)(qi)和(he)與干(gan)式(shi)(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)器(qi)(qi)(qi)的(de)(de)收(shou)塵(chen)原理相同，都是(shi)靠高壓電(dian)(dian)(dian)暈放電(dian)(dian)(dian)使得粉(fen)塵(chen)荷電(dian)(dian)(dian)，荷電(dian)(dian)(dian)后的(de)(de)粉(fen)塵(chen)在電(dian)(dian)(dian)場力的(de)(de)作用下到(dao)達集塵(chen)板/管。干(gan)式(shi)(shi)(shi)電(dian)(dian)(dian)收(shou)塵(chen)器(qi)(qi)(qi)主要處(chu)理含水很低的(de)(de)干(gan)氣體(ti)，濕式(shi)(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)器(qi)(qi)(qi)主要處(chu)理含水較高乃至飽和(he)的(de)(de)濕氣體(ti)。在對(dui)集塵(chen)板/管上(shang)捕集到(dao)的(de)(de)粉(fen)塵(chen)清(qing)除(chu)(chu)方(fang)式(shi)(shi)(shi)上(shang)WESP與DESP有較大(da)區(qu)別，干(gan)式(shi)(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)器(qi)(qi)(qi)一般采(cai)用機械振打或聲(sheng)波清(qing)灰(hui)等(deng)方(fang)式(shi)(shi)(shi)清(qing)除(chu)(chu)電(dian)(dian)(dian)極(ji)上(shang)的(de)(de)積灰(hui)，而濕式(shi)(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)器(qi)(qi)(qi)則(ze)采(cai)用定期沖(chong)洗的(de)(de)方(fang)式(shi)(shi)(shi)，使粉(fen)塵(chen)隨著沖(chong)刷液(ye)的(de)(de)流動而清(qing)除(chu)(chu)。
