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。

濕式電除塵(chen)器(qi)主要有(you)兩(liang)種(zhong)結構(gou)形(xing)式，一種(zhong)是使(shi)用耐(nai)腐蝕(shi)導(dao)(dao)(dao)電材料（可以(yi)為導(dao)(dao)(dao)電性能優良的(de)(de)的(de)(de)非金(jin)屬材料或具(ju)有(you)耐(nai)腐蝕(shi)特性的(de)(de)金(jin)屬材料）做(zuo)集塵(chen)極，另一種(zhong)是用通(tong)過噴水(shui)或溢流水(shui)形(xing)成導(dao)(dao)(dao)電水(shui)膜，利用不導(dao)(dao)(dao)電的(de)(de)非金(jin)屬材料做(zuo)集塵(chen)極。

濕(shi)(shi)式(shi)(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)(chen)(chen)器(qi)和與(yu)干式(shi)(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)(chen)(chen)器(qi)的(de)收塵(chen)(chen)(chen)(chen)(chen)(chen)原理相同，都(dou)是靠高壓電(dian)(dian)(dian)暈放電(dian)(dian)(dian)使得粉(fen)(fen)塵(chen)(chen)(chen)(chen)(chen)(chen)荷電(dian)(dian)(dian)，荷電(dian)(dian)(dian)后的(de)粉(fen)(fen)塵(chen)(chen)(chen)(chen)(chen)(chen)在(zai)電(dian)(dian)(dian)場力的(de)作用(yong)(yong)下到達(da)集塵(chen)(chen)(chen)(chen)(chen)(chen)板/管。干式(shi)(shi)電(dian)(dian)(dian)收塵(chen)(chen)(chen)(chen)(chen)(chen)器(qi)主要處理含(han)(han)水(shui)(shui)很(hen)低的(de)干氣體，濕(shi)(shi)式(shi)(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)(chen)(chen)器(qi)主要處理含(han)(han)水(shui)(shui)較高乃至飽和的(de)濕(shi)(shi)氣體。在(zai)對集塵(chen)(chen)(chen)(chen)(chen)(chen)板/管上捕(bu)集到的(de)粉(fen)(fen)塵(chen)(chen)(chen)(chen)(chen)(chen)清除(chu)方(fang)式(shi)(shi)上WESP與(yu)DESP有較大區別，干式(shi)(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)(chen)(chen)器(qi)一般采用(yong)(yong)機(ji)械振打(da)或聲(sheng)波清灰(hui)等方(fang)式(shi)(shi)清除(chu)電(dian)(dian)(dian)極(ji)上的(de)積灰(hui)，而(er)濕(shi)(shi)式(shi)(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)(chen)(chen)器(qi)則(ze)采用(yong)(yong)定期沖(chong)(chong)洗(xi)的(de)方(fang)式(shi)(shi)，使粉(fen)(fen)塵(chen)(chen)(chen)(chen)(chen)(chen)隨著沖(chong)(chong)刷液的(de)流(liu)動而(er)清除(chu)。
