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)除塵器主(zhu)要有(you)兩種結(jie)構形式，一種是使用(yong)耐(nai)腐蝕導(dao)(dao)電(dian)材(cai)料(liao)（可(ke)以為(wei)導(dao)(dao)電(dian)性能優良的(de)的(de)非金(jin)屬材(cai)料(liao)或具(ju)有(you)耐(nai)腐蝕特性的(de)金(jin)屬材(cai)料(liao)）做集塵極，另一種是用(yong)通(tong)過(guo)噴水或溢流(liu)水形成導(dao)(dao)電(dian)水膜，利(li)用(yong)不導(dao)(dao)電(dian)的(de)非金(jin)屬材(cai)料(liao)做集塵極。

收(shou)塵原理(li)

濕式(shi)電(dian)(dian)(dian)除塵(chen)器(qi)(qi)和與(yu)干式(shi)電(dian)(dian)(dian)除塵(chen)器(qi)(qi)的收塵(chen)原理相同，都是(shi)靠高壓電(dian)(dian)(dian)暈放(fang)電(dian)(dian)(dian)使(shi)(shi)得粉(fen)塵(chen)荷電(dian)(dian)(dian)，荷電(dian)(dian)(dian)后的粉(fen)塵(chen)在電(dian)(dian)(dian)場力的作(zuo)用下(xia)到(dao)達(da)集(ji)塵(chen)板/管。干式(shi)電(dian)(dian)(dian)收塵(chen)器(qi)(qi)主要處理含(han)水很低的干氣體，濕式(shi)電(dian)(dian)(dian)除塵(chen)器(qi)(qi)主要處理含(han)水較(jiao)高乃至(zhi)飽和的濕氣體。在對(dui)集(ji)塵(chen)板/管上捕(bu)集(ji)到(dao)的粉(fen)塵(chen)清除方式(shi)上WESP與(yu)DESP有較(jiao)大區別，干式(shi)電(dian)(dian)(dian)除塵(chen)器(qi)(qi)一般采用機械(xie)振打或聲波清灰(hui)等方式(shi)清除電(dian)(dian)(dian)極上的積灰(hui)，而濕式(shi)電(dian)(dian)(dian)除塵(chen)器(qi)(qi)則采用定期沖洗的方式(shi)，使(shi)(shi)粉(fen)塵(chen)隨著(zhu)沖刷液的流(liu)動(dong)而清除。
