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)(dian)除塵(chen)器主要有(you)兩種(zhong)結(jie)構形式，一種(zhong)是使用耐腐蝕(shi)導電(dian)(dian)材(cai)料（可以為導電(dian)(dian)性(xing)能優(you)良的的非(fei)金(jin)屬(shu)材(cai)料或具有(you)耐腐蝕(shi)特性(xing)的金(jin)屬(shu)材(cai)料）做(zuo)集塵(chen)極，另一種(zhong)是用通過噴水或溢流(liu)水形成(cheng)導電(dian)(dian)水膜，利用不導電(dian)(dian)的非(fei)金(jin)屬(shu)材(cai)料做(zuo)集塵(chen)極。

濕(shi)式(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)和與干式(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)的(de)(de)收塵(chen)(chen)(chen)原理(li)相同，都是靠(kao)高壓電(dian)(dian)(dian)暈放電(dian)(dian)(dian)使(shi)得粉(fen)(fen)(fen)塵(chen)(chen)(chen)荷電(dian)(dian)(dian)，荷電(dian)(dian)(dian)后的(de)(de)粉(fen)(fen)(fen)塵(chen)(chen)(chen)在(zai)電(dian)(dian)(dian)場力的(de)(de)作(zuo)用下到(dao)達集塵(chen)(chen)(chen)板(ban)/管(guan)。干式(shi)電(dian)(dian)(dian)收塵(chen)(chen)(chen)器(qi)主(zhu)要處理(li)含水(shui)很低(di)的(de)(de)干氣體(ti)，濕(shi)式(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)主(zhu)要處理(li)含水(shui)較高乃至(zhi)飽和的(de)(de)濕(shi)氣體(ti)。在(zai)對(dui)集塵(chen)(chen)(chen)板(ban)/管(guan)上(shang)捕集到(dao)的(de)(de)粉(fen)(fen)(fen)塵(chen)(chen)(chen)清(qing)(qing)除(chu)方式(shi)上(shang)WESP與DESP有(you)較大區別(bie)，干式(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)一般采(cai)用機(ji)械振打或聲波清(qing)(qing)灰等方式(shi)清(qing)(qing)除(chu)電(dian)(dian)(dian)極上(shang)的(de)(de)積灰，而濕(shi)式(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)則采(cai)用定(ding)期沖洗的(de)(de)方式(shi)，使(shi)粉(fen)(fen)(fen)塵(chen)(chen)(chen)隨著(zhu)沖刷液的(de)(de)流動而清(qing)(qing)除(chu)。
