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(qi)主(zhu)要有兩種結(jie)構形(xing)式，一種是使用耐腐蝕導電(dian)材料（可以為導電(dian)性能優(you)良的的非金屬(shu)材料或(huo)具有耐腐蝕特(te)性的金屬(shu)材料）做(zuo)集(ji)塵極(ji)，另(ling)一種是用通過噴(pen)水或(huo)溢流(liu)水形(xing)成導電(dian)水膜，利用不導電(dian)的非金屬(shu)材料做(zuo)集(ji)塵極(ji)。

濕(shi)式(shi)電(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)(chen)(chen)器(qi)(qi)和(he)與干式(shi)電(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)(chen)(chen)器(qi)(qi)的(de)(de)(de)收塵(chen)(chen)(chen)(chen)(chen)(chen)原理相(xiang)同，都是靠高(gao)壓電(dian)(dian)(dian)暈(yun)放電(dian)(dian)(dian)使(shi)得粉(fen)塵(chen)(chen)(chen)(chen)(chen)(chen)荷電(dian)(dian)(dian)，荷電(dian)(dian)(dian)后的(de)(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)(chen)(chen)在電(dian)(dian)(dian)場力的(de)(de)(de)作用下到(dao)達集(ji)(ji)塵(chen)(chen)(chen)(chen)(chen)(chen)板/管(guan)。干式(shi)電(dian)(dian)(dian)收塵(chen)(chen)(chen)(chen)(chen)(chen)器(qi)(qi)主(zhu)(zhu)要處理含(han)水很(hen)低的(de)(de)(de)干氣體，濕(shi)式(shi)電(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)(chen)(chen)器(qi)(qi)主(zhu)(zhu)要處理含(han)水較高(gao)乃至(zhi)飽和(he)的(de)(de)(de)濕(shi)氣體。在對(dui)集(ji)(ji)塵(chen)(chen)(chen)(chen)(chen)(chen)板/管(guan)上(shang)捕集(ji)(ji)到(dao)的(de)(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)(chen)(chen)清除方(fang)(fang)式(shi)上(shang)WESP與DESP有較大區別，干式(shi)電(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)(chen)(chen)器(qi)(qi)一般采用機(ji)械振打或聲波清灰等方(fang)(fang)式(shi)清除電(dian)(dian)(dian)極(ji)上(shang)的(de)(de)(de)積灰，而濕(shi)式(shi)電(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)(chen)(chen)器(qi)(qi)則采用定期(qi)沖(chong)(chong)洗的(de)(de)(de)方(fang)(fang)式(shi)，使(shi)粉(fen)塵(chen)(chen)(chen)(chen)(chen)(chen)隨著(zhu)沖(chong)(chong)刷液的(de)(de)(de)流動而清除。
