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)(dian)除(chu)塵(chen)器(qi)主要有(you)兩(liang)種(zhong)(zhong)結構形(xing)式，一(yi)種(zhong)(zhong)是使用耐腐(fu)(fu)蝕導(dao)電(dian)(dian)材(cai)(cai)(cai)料(liao)（可以為(wei)導(dao)電(dian)(dian)性能優良(liang)的(de)(de)的(de)(de)非金屬(shu)材(cai)(cai)(cai)料(liao)或具有(you)耐腐(fu)(fu)蝕特性的(de)(de)金屬(shu)材(cai)(cai)(cai)料(liao)）做集塵(chen)極，另一(yi)種(zhong)(zhong)是用通(tong)過噴水(shui)(shui)(shui)或溢流水(shui)(shui)(shui)形(xing)成導(dao)電(dian)(dian)水(shui)(shui)(shui)膜，利用不導(dao)電(dian)(dian)的(de)(de)非金屬(shu)材(cai)(cai)(cai)料(liao)做集塵(chen)極。

收塵原理

濕式(shi)電(dian)(dian)(dian)除塵(chen)(chen)器(qi)(qi)和與干式(shi)電(dian)(dian)(dian)除塵(chen)(chen)器(qi)(qi)的(de)(de)收塵(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)塵(chen)(chen)荷電(dian)(dian)(dian)，荷電(dian)(dian)(dian)后(hou)的(de)(de)粉(fen)塵(chen)(chen)在(zai)電(dian)(dian)(dian)場力的(de)(de)作用(yong)下到達集塵(chen)(chen)板/管(guan)。干式(shi)電(dian)(dian)(dian)收塵(chen)(chen)器(qi)(qi)主(zhu)要(yao)處理含水(shui)很低的(de)(de)干氣(qi)體(ti)，濕式(shi)電(dian)(dian)(dian)除塵(chen)(chen)器(qi)(qi)主(zhu)要(yao)處理含水(shui)較高乃至飽和的(de)(de)濕氣(qi)體(ti)。在(zai)對(dui)集塵(chen)(chen)板/管(guan)上捕(bu)集到的(de)(de)粉(fen)塵(chen)(chen)清(qing)除方(fang)式(shi)上WESP與DESP有(you)較大區別，干式(shi)電(dian)(dian)(dian)除塵(chen)(chen)器(qi)(qi)一般采用(yong)機械(xie)振打(da)或聲波清(qing)灰(hui)等方(fang)式(shi)清(qing)除電(dian)(dian)(dian)極上的(de)(de)積灰(hui)，而濕式(shi)電(dian)(dian)(dian)除塵(chen)(chen)器(qi)(qi)則采用(yong)定期沖(chong)洗的(de)(de)方(fang)式(shi)，使粉(fen)塵(chen)(chen)隨著沖(chong)刷液的(de)(de)流動而清(qing)除。
