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(shi)式(shi)電(dian)(dian)(dian)除塵器(qi)主(zhu)要有兩種(zhong)(zhong)結構形式(shi)，一種(zhong)(zhong)是使用(yong)耐(nai)腐蝕導電(dian)(dian)(dian)材(cai)(cai)料(liao)（可(ke)以為導電(dian)(dian)(dian)性(xing)能優良的(de)的(de)非金屬材(cai)(cai)料(liao)或具有耐(nai)腐蝕特(te)性(xing)的(de)金屬材(cai)(cai)料(liao)）做集(ji)(ji)塵極(ji)，另(ling)一種(zhong)(zhong)是用(yong)通過噴(pen)水或溢(yi)流水形成導電(dian)(dian)(dian)水膜，利(li)用(yong)不導電(dian)(dian)(dian)的(de)非金屬材(cai)(cai)料(liao)做集(ji)(ji)塵極(ji)。

收(shou)塵原理

濕(shi)式(shi)(shi)電(dian)(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)器和(he)(he)與干式(shi)(shi)電(dian)(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)器的(de)(de)收(shou)塵(chen)(chen)(chen)原理(li)相同，都是靠高壓(ya)電(dian)(dian)(dian)(dian)暈(yun)放電(dian)(dian)(dian)(dian)使得(de)粉(fen)塵(chen)(chen)(chen)荷(he)電(dian)(dian)(dian)(dian)，荷(he)電(dian)(dian)(dian)(dian)后的(de)(de)粉(fen)塵(chen)(chen)(chen)在電(dian)(dian)(dian)(dian)場力的(de)(de)作用下到達集(ji)塵(chen)(chen)(chen)板(ban)(ban)/管(guan)(guan)。干式(shi)(shi)電(dian)(dian)(dian)(dian)收(shou)塵(chen)(chen)(chen)器主要(yao)處理(li)含(han)(han)水很(hen)低的(de)(de)干氣體(ti)，濕(shi)式(shi)(shi)電(dian)(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)器主要(yao)處理(li)含(han)(han)水較高乃至(zhi)飽和(he)(he)的(de)(de)濕(shi)氣體(ti)。在對集(ji)塵(chen)(chen)(chen)板(ban)(ban)/管(guan)(guan)上捕集(ji)到的(de)(de)粉(fen)塵(chen)(chen)(chen)清除(chu)(chu)(chu)方式(shi)(shi)上WESP與DESP有較大區別，干式(shi)(shi)電(dian)(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)器一般采用機械振打或聲波清灰等方式(shi)(shi)清除(chu)(chu)(chu)電(dian)(dian)(dian)(dian)極上的(de)(de)積灰，而濕(shi)式(shi)(shi)電(dian)(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)(chen)(chen)器則采用定(ding)期沖(chong)洗的(de)(de)方式(shi)(shi)，使粉(fen)塵(chen)(chen)(chen)隨著沖(chong)刷液的(de)(de)流動(dong)而清除(chu)(chu)(chu)。
