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)器主要有(you)(you)兩種(zhong)結構形式(shi)，一種(zhong)是(shi)使用(yong)耐腐(fu)蝕導(dao)電(dian)材料(liao)（可以為導(dao)電(dian)性(xing)(xing)能優(you)良的(de)(de)的(de)(de)非(fei)金(jin)屬(shu)材料(liao)或具有(you)(you)耐腐(fu)蝕特(te)性(xing)(xing)的(de)(de)金(jin)屬(shu)材料(liao)）做集塵(chen)極，另一種(zhong)是(shi)用(yong)通過噴(pen)水(shui)或溢(yi)流水(shui)形成(cheng)導(dao)電(dian)水(shui)膜(mo)，利用(yong)不(bu)導(dao)電(dian)的(de)(de)非(fei)金(jin)屬(shu)材料(liao)做集塵(chen)極。

收塵(chen)原理

濕式(shi)電(dian)(dian)(dian)(dian)除(chu)塵器(qi)(qi)(qi)和與干式(shi)電(dian)(dian)(dian)(dian)除(chu)塵器(qi)(qi)(qi)的(de)(de)(de)收塵原理(li)相同(tong)，都是靠高(gao)壓電(dian)(dian)(dian)(dian)暈放電(dian)(dian)(dian)(dian)使得粉塵荷(he)(he)電(dian)(dian)(dian)(dian)，荷(he)(he)電(dian)(dian)(dian)(dian)后(hou)的(de)(de)(de)粉塵在(zai)電(dian)(dian)(dian)(dian)場力的(de)(de)(de)作用下到達(da)集塵板/管。干式(shi)電(dian)(dian)(dian)(dian)收塵器(qi)(qi)(qi)主要處(chu)理(li)含水(shui)很低的(de)(de)(de)干氣(qi)體，濕式(shi)電(dian)(dian)(dian)(dian)除(chu)塵器(qi)(qi)(qi)主要處(chu)理(li)含水(shui)較高(gao)乃至飽(bao)和的(de)(de)(de)濕氣(qi)體。在(zai)對集塵板/管上(shang)(shang)捕集到的(de)(de)(de)粉塵清除(chu)方式(shi)上(shang)(shang)WESP與DESP有較大(da)區別，干式(shi)電(dian)(dian)(dian)(dian)除(chu)塵器(qi)(qi)(qi)一般采用機(ji)械振打(da)或聲波(bo)清灰等(deng)方式(shi)清除(chu)電(dian)(dian)(dian)(dian)極(ji)上(shang)(shang)的(de)(de)(de)積灰，而(er)濕式(shi)電(dian)(dian)(dian)(dian)除(chu)塵器(qi)(qi)(qi)則采用定期沖(chong)洗(xi)的(de)(de)(de)方式(shi)，使粉塵隨(sui)著(zhu)沖(chong)刷液的(de)(de)(de)流動而(er)清除(chu)。
