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)除塵(chen)器(qi)主要有(you)(you)兩種(zhong)結構形式(shi)，一(yi)種(zhong)是使用耐腐蝕(shi)導(dao)(dao)電(dian)材料(liao)（可以為導(dao)(dao)電(dian)性(xing)能(neng)優良的的非金(jin)屬(shu)材料(liao)或具(ju)有(you)(you)耐腐蝕(shi)特(te)性(xing)的金(jin)屬(shu)材料(liao)）做集(ji)塵(chen)極(ji)，另(ling)一(yi)種(zhong)是用通過噴水(shui)或溢流(liu)水(shui)形成導(dao)(dao)電(dian)水(shui)膜，利用不導(dao)(dao)電(dian)的非金(jin)屬(shu)材料(liao)做集(ji)塵(chen)極(ji)。

收塵原理

濕(shi)(shi)式(shi)(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)(qi)(qi)和與(yu)干(gan)式(shi)(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)(qi)(qi)的(de)(de)(de)收塵(chen)(chen)(chen)原理(li)相同(tong)，都是靠高壓電(dian)(dian)(dian)暈放(fang)電(dian)(dian)(dian)使得粉(fen)(fen)塵(chen)(chen)(chen)荷電(dian)(dian)(dian)，荷電(dian)(dian)(dian)后的(de)(de)(de)粉(fen)(fen)塵(chen)(chen)(chen)在(zai)電(dian)(dian)(dian)場力的(de)(de)(de)作用下到達集(ji)塵(chen)(chen)(chen)板/管(guan)。干(gan)式(shi)(shi)電(dian)(dian)(dian)收塵(chen)(chen)(chen)器(qi)(qi)(qi)主要(yao)處(chu)理(li)含(han)水很低的(de)(de)(de)干(gan)氣體(ti)，濕(shi)(shi)式(shi)(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)(qi)(qi)主要(yao)處(chu)理(li)含(han)水較高乃至飽和的(de)(de)(de)濕(shi)(shi)氣體(ti)。在(zai)對(dui)集(ji)塵(chen)(chen)(chen)板/管(guan)上(shang)(shang)捕集(ji)到的(de)(de)(de)粉(fen)(fen)塵(chen)(chen)(chen)清(qing)除(chu)方(fang)(fang)式(shi)(shi)上(shang)(shang)WESP與(yu)DESP有較大區別，干(gan)式(shi)(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)(qi)(qi)一(yi)般采(cai)用機械振打或聲波清(qing)灰等方(fang)(fang)式(shi)(shi)清(qing)除(chu)電(dian)(dian)(dian)極上(shang)(shang)的(de)(de)(de)積灰，而濕(shi)(shi)式(shi)(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)(qi)(qi)則采(cai)用定期沖(chong)洗的(de)(de)(de)方(fang)(fang)式(shi)(shi)，使粉(fen)(fen)塵(chen)(chen)(chen)隨著(zhu)沖(chong)刷(shua)液的(de)(de)(de)流動(dong)而清(qing)除(chu)。
