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(dian)除塵(chen)器主要有兩種(zhong)結構形(xing)(xing)式，一種(zhong)是使用耐腐蝕導電(dian)材(cai)(cai)料(liao)（可以為(wei)導電(dian)性能優(you)良的的非(fei)(fei)金屬(shu)材(cai)(cai)料(liao)或具(ju)有耐腐蝕特性的金屬(shu)材(cai)(cai)料(liao)）做集(ji)塵(chen)極，另一種(zhong)是用通過噴水(shui)或溢流水(shui)形(xing)(xing)成導電(dian)水(shui)膜，利(li)用不(bu)導電(dian)的非(fei)(fei)金屬(shu)材(cai)(cai)料(liao)做集(ji)塵(chen)極。

收塵原理

濕式(shi)電(dian)(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)器(qi)和與(yu)干式(shi)電(dian)(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)器(qi)的收(shou)塵(chen)(chen)(chen)(chen)原理(li)相同，都(dou)是靠高壓電(dian)(dian)(dian)(dian)(dian)暈放電(dian)(dian)(dian)(dian)(dian)使得粉(fen)塵(chen)(chen)(chen)(chen)荷(he)電(dian)(dian)(dian)(dian)(dian)，荷(he)電(dian)(dian)(dian)(dian)(dian)后的粉(fen)塵(chen)(chen)(chen)(chen)在電(dian)(dian)(dian)(dian)(dian)場(chang)力的作用(yong)(yong)下到(dao)達集塵(chen)(chen)(chen)(chen)板/管。干式(shi)電(dian)(dian)(dian)(dian)(dian)收(shou)塵(chen)(chen)(chen)(chen)器(qi)主(zhu)(zhu)要處(chu)理(li)含(han)(han)水(shui)很(hen)低的干氣體，濕式(shi)電(dian)(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)器(qi)主(zhu)(zhu)要處(chu)理(li)含(han)(han)水(shui)較高乃至飽和的濕氣體。在對集塵(chen)(chen)(chen)(chen)板/管上(shang)(shang)捕集到(dao)的粉(fen)塵(chen)(chen)(chen)(chen)清除(chu)(chu)方式(shi)上(shang)(shang)WESP與(yu)DESP有較大區別(bie)，干式(shi)電(dian)(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)器(qi)一般采用(yong)(yong)機械(xie)振打或聲波清灰等方式(shi)清除(chu)(chu)電(dian)(dian)(dian)(dian)(dian)極上(shang)(shang)的積灰，而濕式(shi)電(dian)(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)器(qi)則(ze)采用(yong)(yong)定期沖(chong)洗的方式(shi)，使粉(fen)塵(chen)(chen)(chen)(chen)隨著沖(chong)刷液(ye)的流動(dong)而清除(chu)(chu)。
