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(chu)塵器主要有兩種結構形式，一(yi)種是使用(yong)(yong)(yong)耐腐蝕(shi)導(dao)電(dian)材料（可以為導(dao)電(dian)性能優(you)良(liang)的(de)的(de)非金(jin)屬材料或具有耐腐蝕(shi)特性的(de)金(jin)屬材料）做集塵極，另一(yi)種是用(yong)(yong)(yong)通過噴水(shui)(shui)或溢流水(shui)(shui)形成導(dao)電(dian)水(shui)(shui)膜，利(li)用(yong)(yong)(yong)不導(dao)電(dian)的(de)非金(jin)屬材料做集塵極。

濕(shi)式(shi)(shi)電(dian)(dian)(dian)除(chu)塵(chen)器(qi)和與干式(shi)(shi)電(dian)(dian)(dian)除(chu)塵(chen)器(qi)的(de)(de)(de)收(shou)塵(chen)原理相同，都(dou)是靠(kao)高壓電(dian)(dian)(dian)暈(yun)放(fang)電(dian)(dian)(dian)使(shi)得粉(fen)(fen)塵(chen)荷電(dian)(dian)(dian)，荷電(dian)(dian)(dian)后(hou)的(de)(de)(de)粉(fen)(fen)塵(chen)在(zai)電(dian)(dian)(dian)場(chang)力的(de)(de)(de)作用(yong)下到達集塵(chen)板/管(guan)(guan)。干式(shi)(shi)電(dian)(dian)(dian)收(shou)塵(chen)器(qi)主(zhu)要處(chu)理含(han)水(shui)(shui)很(hen)低(di)的(de)(de)(de)干氣體，濕(shi)式(shi)(shi)電(dian)(dian)(dian)除(chu)塵(chen)器(qi)主(zhu)要處(chu)理含(han)水(shui)(shui)較高乃至飽和的(de)(de)(de)濕(shi)氣體。在(zai)對集塵(chen)板/管(guan)(guan)上(shang)捕集到的(de)(de)(de)粉(fen)(fen)塵(chen)清除(chu)方(fang)式(shi)(shi)上(shang)WESP與DESP有較大區別，干式(shi)(shi)電(dian)(dian)(dian)除(chu)塵(chen)器(qi)一(yi)般采(cai)用(yong)機械振(zhen)打(da)或聲波清灰等方(fang)式(shi)(shi)清除(chu)電(dian)(dian)(dian)極上(shang)的(de)(de)(de)積灰，而濕(shi)式(shi)(shi)電(dian)(dian)(dian)除(chu)塵(chen)器(qi)則采(cai)用(yong)定期沖洗的(de)(de)(de)方(fang)式(shi)(shi)，使(shi)粉(fen)(fen)塵(chen)隨著沖刷液的(de)(de)(de)流動而清除(chu)。
