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(qi)主要有(you)兩(liang)種(zhong)結構形式(shi)，一(yi)種(zhong)是使用(yong)耐腐(fu)蝕(shi)導電材(cai)料（可以為導電性能優良的的非金屬材(cai)料或具有(you)耐腐(fu)蝕(shi)特性的金屬材(cai)料）做集(ji)(ji)塵極，另一(yi)種(zhong)是用(yong)通過(guo)噴水或溢流水形成導電水膜，利(li)用(yong)不導電的非金屬材(cai)料做集(ji)(ji)塵極。

收塵原(yuan)理

濕(shi)式(shi)(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器(qi)(qi)和與(yu)干(gan)式(shi)(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器(qi)(qi)的(de)(de)(de)收塵(chen)(chen)(chen)(chen)原(yuan)理相同，都是靠高(gao)壓電(dian)(dian)(dian)暈放(fang)電(dian)(dian)(dian)使(shi)得(de)粉(fen)塵(chen)(chen)(chen)(chen)荷電(dian)(dian)(dian)，荷電(dian)(dian)(dian)后的(de)(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)在電(dian)(dian)(dian)場力(li)的(de)(de)(de)作用下到達集塵(chen)(chen)(chen)(chen)板/管(guan)。干(gan)式(shi)(shi)電(dian)(dian)(dian)收塵(chen)(chen)(chen)(chen)器(qi)(qi)主要處理含(han)水很低的(de)(de)(de)干(gan)氣(qi)體，濕(shi)式(shi)(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器(qi)(qi)主要處理含(han)水較(jiao)高(gao)乃至飽和的(de)(de)(de)濕(shi)氣(qi)體。在對集塵(chen)(chen)(chen)(chen)板/管(guan)上捕集到的(de)(de)(de)粉(fen)塵(chen)(chen)(chen)(chen)清(qing)除(chu)方式(shi)(shi)上WESP與(yu)DESP有較(jiao)大(da)區別，干(gan)式(shi)(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器(qi)(qi)一般采(cai)用機械振打(da)或聲波清(qing)灰(hui)等方式(shi)(shi)清(qing)除(chu)電(dian)(dian)(dian)極上的(de)(de)(de)積灰(hui)，而濕(shi)式(shi)(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)器(qi)(qi)則采(cai)用定期(qi)沖洗的(de)(de)(de)方式(shi)(shi)，使(shi)粉(fen)塵(chen)(chen)(chen)(chen)隨著沖刷液的(de)(de)(de)流動而清(qing)除(chu)。
