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。

濕式電除塵器主(zhu)要有(you)兩種(zhong)(zhong)結構形式，一(yi)種(zhong)(zhong)是(shi)使用耐腐蝕導電材(cai)(cai)料(liao)（可以(yi)為導電性(xing)(xing)能優良的(de)(de)的(de)(de)非金屬(shu)材(cai)(cai)料(liao)或具有(you)耐腐蝕特性(xing)(xing)的(de)(de)金屬(shu)材(cai)(cai)料(liao)）做集塵極(ji)，另一(yi)種(zhong)(zhong)是(shi)用通過噴水或溢流(liu)水形成(cheng)導電水膜，利用不(bu)導電的(de)(de)非金屬(shu)材(cai)(cai)料(liao)做集塵極(ji)。

收塵原理

濕式(shi)電(dian)(dian)(dian)(dian)除(chu)(chu)(chu)塵器(qi)(qi)(qi)和(he)與干(gan)式(shi)電(dian)(dian)(dian)(dian)除(chu)(chu)(chu)塵器(qi)(qi)(qi)的(de)(de)收塵原(yuan)理(li)相同，都是靠高(gao)(gao)壓電(dian)(dian)(dian)(dian)暈放電(dian)(dian)(dian)(dian)使得粉(fen)塵荷電(dian)(dian)(dian)(dian)，荷電(dian)(dian)(dian)(dian)后的(de)(de)粉(fen)塵在電(dian)(dian)(dian)(dian)場力的(de)(de)作用(yong)下到(dao)達集塵板/管。干(gan)式(shi)電(dian)(dian)(dian)(dian)收塵器(qi)(qi)(qi)主要處理(li)含水很低的(de)(de)干(gan)氣體(ti)，濕式(shi)電(dian)(dian)(dian)(dian)除(chu)(chu)(chu)塵器(qi)(qi)(qi)主要處理(li)含水較高(gao)(gao)乃至飽和(he)的(de)(de)濕氣體(ti)。在對(dui)集塵板/管上捕集到(dao)的(de)(de)粉(fen)塵清(qing)除(chu)(chu)(chu)方式(shi)上WESP與DESP有較大區別(bie)，干(gan)式(shi)電(dian)(dian)(dian)(dian)除(chu)(chu)(chu)塵器(qi)(qi)(qi)一般采(cai)用(yong)機械振打(da)或聲波清(qing)灰等方式(shi)清(qing)除(chu)(chu)(chu)電(dian)(dian)(dian)(dian)極上的(de)(de)積灰，而濕式(shi)電(dian)(dian)(dian)(dian)除(chu)(chu)(chu)塵器(qi)(qi)(qi)則采(cai)用(yong)定期沖(chong)洗的(de)(de)方式(shi)，使粉(fen)塵隨著沖(chong)刷液的(de)(de)流動而清(qing)除(chu)(chu)(chu)。
