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)除塵(chen)器主要有(you)兩種結構形(xing)式，一種是(shi)(shi)使(shi)用耐腐(fu)(fu)蝕(shi)(shi)導(dao)(dao)電(dian)(dian)材(cai)料(liao)（可以為導(dao)(dao)電(dian)(dian)性能優良(liang)的(de)(de)的(de)(de)非金屬材(cai)料(liao)或(huo)具有(you)耐腐(fu)(fu)蝕(shi)(shi)特(te)性的(de)(de)金屬材(cai)料(liao)）做(zuo)集(ji)塵(chen)極(ji)，另一種是(shi)(shi)用通過噴水(shui)或(huo)溢流水(shui)形(xing)成導(dao)(dao)電(dian)(dian)水(shui)膜，利用不導(dao)(dao)電(dian)(dian)的(de)(de)非金屬材(cai)料(liao)做(zuo)集(ji)塵(chen)極(ji)。

收塵原理

濕(shi)式(shi)(shi)(shi)電(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)器(qi)和與(yu)干式(shi)(shi)(shi)電(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)器(qi)的(de)收(shou)(shou)塵(chen)(chen)(chen)(chen)原理相同，都是靠(kao)高(gao)壓電(dian)(dian)(dian)(dian)暈放電(dian)(dian)(dian)(dian)使(shi)得粉(fen)塵(chen)(chen)(chen)(chen)荷電(dian)(dian)(dian)(dian)，荷電(dian)(dian)(dian)(dian)后的(de)粉(fen)塵(chen)(chen)(chen)(chen)在電(dian)(dian)(dian)(dian)場力(li)的(de)作用(yong)下到達集塵(chen)(chen)(chen)(chen)板/管(guan)(guan)。干式(shi)(shi)(shi)電(dian)(dian)(dian)(dian)收(shou)(shou)塵(chen)(chen)(chen)(chen)器(qi)主要處(chu)理含(han)水很(hen)低(di)的(de)干氣體(ti)，濕(shi)式(shi)(shi)(shi)電(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)器(qi)主要處(chu)理含(han)水較高(gao)乃(nai)至飽(bao)和的(de)濕(shi)氣體(ti)。在對集塵(chen)(chen)(chen)(chen)板/管(guan)(guan)上捕集到的(de)粉(fen)塵(chen)(chen)(chen)(chen)清除方式(shi)(shi)(shi)上WESP與(yu)DESP有較大區別，干式(shi)(shi)(shi)電(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)器(qi)一般采(cai)用(yong)機械振打或(huo)聲波清灰等方式(shi)(shi)(shi)清除電(dian)(dian)(dian)(dian)極上的(de)積(ji)灰，而濕(shi)式(shi)(shi)(shi)電(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)器(qi)則采(cai)用(yong)定期(qi)沖(chong)洗(xi)的(de)方式(shi)(shi)(shi)，使(shi)粉(fen)塵(chen)(chen)(chen)(chen)隨著沖(chong)刷液的(de)流動而清除。
