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。

濕式電除塵器主要有(you)兩(liang)種(zhong)(zhong)(zhong)結構形式，一(yi)種(zhong)(zhong)(zhong)是(shi)使(shi)用耐腐(fu)蝕導電材(cai)料（可以(yi)為導電性能優(you)良的的非(fei)金(jin)屬材(cai)料或具有(you)耐腐(fu)蝕特性的金(jin)屬材(cai)料）做集(ji)塵極，另(ling)一(yi)種(zhong)(zhong)(zhong)是(shi)用通過噴水(shui)(shui)或溢流水(shui)(shui)形成(cheng)導電水(shui)(shui)膜，利用不導電的非(fei)金(jin)屬材(cai)料做集(ji)塵極。

收塵原理

濕(shi)式電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器(qi)和(he)與干式電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器(qi)的收(shou)塵(chen)(chen)(chen)原理相同，都(dou)是(shi)靠高(gao)壓電(dian)(dian)(dian)暈(yun)放電(dian)(dian)(dian)使得(de)粉(fen)(fen)塵(chen)(chen)(chen)荷電(dian)(dian)(dian)，荷電(dian)(dian)(dian)后的粉(fen)(fen)塵(chen)(chen)(chen)在(zai)電(dian)(dian)(dian)場力(li)的作用下到達集塵(chen)(chen)(chen)板/管(guan)。干式電(dian)(dian)(dian)收(shou)塵(chen)(chen)(chen)器(qi)主(zhu)要處理含水(shui)很低的干氣體，濕(shi)式電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器(qi)主(zhu)要處理含水(shui)較高(gao)乃至飽和(he)的濕(shi)氣體。在(zai)對集塵(chen)(chen)(chen)板/管(guan)上(shang)捕(bu)集到的粉(fen)(fen)塵(chen)(chen)(chen)清(qing)除(chu)(chu)方式上(shang)WESP與DESP有(you)較大區別，干式電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器(qi)一般采用機械振打或聲波(bo)清(qing)灰(hui)等方式清(qing)除(chu)(chu)電(dian)(dian)(dian)極上(shang)的積灰(hui)，而(er)濕(shi)式電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器(qi)則采用定期沖洗的方式，使粉(fen)(fen)塵(chen)(chen)(chen)隨著沖刷液(ye)的流動而(er)清(qing)除(chu)(chu)。
