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(shi)電除塵器主要有(you)(you)兩(liang)種結構形式(shi)，一(yi)(yi)種是(shi)使用(yong)耐(nai)腐(fu)蝕導(dao)(dao)電材(cai)(cai)料(liao)（可以為(wei)導(dao)(dao)電性能(neng)優良的(de)的(de)非金(jin)(jin)屬(shu)材(cai)(cai)料(liao)或(huo)具有(you)(you)耐(nai)腐(fu)蝕特性的(de)金(jin)(jin)屬(shu)材(cai)(cai)料(liao)）做集(ji)(ji)塵極(ji)，另一(yi)(yi)種是(shi)用(yong)通過噴水或(huo)溢流水形成導(dao)(dao)電水膜(mo)，利用(yong)不導(dao)(dao)電的(de)非金(jin)(jin)屬(shu)材(cai)(cai)料(liao)做集(ji)(ji)塵極(ji)。

濕(shi)式(shi)(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)器(qi)(qi)和與干式(shi)(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)器(qi)(qi)的(de)(de)收(shou)塵(chen)(chen)(chen)(chen)原理相同(tong)，都是靠高(gao)壓電(dian)(dian)(dian)暈放電(dian)(dian)(dian)使得粉塵(chen)(chen)(chen)(chen)荷電(dian)(dian)(dian)，荷電(dian)(dian)(dian)后的(de)(de)粉塵(chen)(chen)(chen)(chen)在電(dian)(dian)(dian)場力的(de)(de)作用下到達集塵(chen)(chen)(chen)(chen)板/管。干式(shi)(shi)(shi)電(dian)(dian)(dian)收(shou)塵(chen)(chen)(chen)(chen)器(qi)(qi)主(zhu)要處理含(han)水很(hen)低的(de)(de)干氣體(ti)(ti)，濕(shi)式(shi)(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)器(qi)(qi)主(zhu)要處理含(han)水較高(gao)乃至飽和的(de)(de)濕(shi)氣體(ti)(ti)。在對集塵(chen)(chen)(chen)(chen)板/管上捕集到的(de)(de)粉塵(chen)(chen)(chen)(chen)清(qing)除(chu)(chu)方式(shi)(shi)(shi)上WESP與DESP有(you)較大區別，干式(shi)(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)器(qi)(qi)一般采(cai)用機械振(zhen)打或聲波清(qing)灰等方式(shi)(shi)(shi)清(qing)除(chu)(chu)電(dian)(dian)(dian)極上的(de)(de)積(ji)灰，而濕(shi)式(shi)(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)器(qi)(qi)則采(cai)用定期沖洗的(de)(de)方式(shi)(shi)(shi)，使粉塵(chen)(chen)(chen)(chen)隨著沖刷液(ye)的(de)(de)流動而清(qing)除(chu)(chu)。
