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(chen)器主要(yao)有兩種結構形(xing)式，一(yi)種是(shi)使用(yong)耐腐(fu)蝕(shi)導電材(cai)料（可以為導電性(xing)能優良的的非金(jin)(jin)屬材(cai)料或具(ju)有耐腐(fu)蝕(shi)特性(xing)的金(jin)(jin)屬材(cai)料）做集塵(chen)極，另一(yi)種是(shi)用(yong)通過噴水(shui)或溢流水(shui)形(xing)成導電水(shui)膜(mo)，利用(yong)不導電的非金(jin)(jin)屬材(cai)料做集塵(chen)極。

濕(shi)(shi)式(shi)電(dian)(dian)除塵(chen)(chen)(chen)器(qi)(qi)(qi)和與干式(shi)電(dian)(dian)除塵(chen)(chen)(chen)器(qi)(qi)(qi)的收塵(chen)(chen)(chen)原理(li)相(xiang)同，都是靠高壓(ya)電(dian)(dian)暈(yun)放電(dian)(dian)使得粉塵(chen)(chen)(chen)荷(he)電(dian)(dian)，荷(he)電(dian)(dian)后的粉塵(chen)(chen)(chen)在(zai)(zai)電(dian)(dian)場(chang)力的作(zuo)用(yong)下到達集(ji)塵(chen)(chen)(chen)板(ban)/管(guan)。干式(shi)電(dian)(dian)收塵(chen)(chen)(chen)器(qi)(qi)(qi)主要(yao)(yao)處理(li)含(han)水很低的干氣體(ti)(ti)(ti)，濕(shi)(shi)式(shi)電(dian)(dian)除塵(chen)(chen)(chen)器(qi)(qi)(qi)主要(yao)(yao)處理(li)含(han)水較高乃至飽(bao)和的濕(shi)(shi)氣體(ti)(ti)(ti)。在(zai)(zai)對集(ji)塵(chen)(chen)(chen)板(ban)/管(guan)上(shang)(shang)捕集(ji)到的粉塵(chen)(chen)(chen)清(qing)(qing)除方式(shi)上(shang)(shang)WESP與DESP有(you)較大區(qu)別(bie)，干式(shi)電(dian)(dian)除塵(chen)(chen)(chen)器(qi)(qi)(qi)一般采(cai)用(yong)機械振打或聲波清(qing)(qing)灰(hui)等方式(shi)清(qing)(qing)除電(dian)(dian)極上(shang)(shang)的積灰(hui)，而濕(shi)(shi)式(shi)電(dian)(dian)除塵(chen)(chen)(chen)器(qi)(qi)(qi)則采(cai)用(yong)定期沖(chong)(chong)洗的方式(shi)，使粉塵(chen)(chen)(chen)隨著沖(chong)(chong)刷液的流動而清(qing)(qing)除。
