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)除塵器主要有兩種(zhong)(zhong)(zhong)結構形式，一種(zhong)(zhong)(zhong)是使(shi)用耐腐蝕導電(dian)材料（可以為(wei)導電(dian)性能優良的的非(fei)金(jin)屬(shu)材料或具有耐腐蝕特性的金(jin)屬(shu)材料）做集塵極，另(ling)一種(zhong)(zhong)(zhong)是用通過噴(pen)水(shui)或溢(yi)流水(shui)形成導電(dian)水(shui)膜，利用不導電(dian)的非(fei)金(jin)屬(shu)材料做集塵極。

收塵(chen)原理(li)

濕(shi)式(shi)(shi)(shi)電(dian)(dian)(dian)(dian)除(chu)塵(chen)器(qi)(qi)和與干(gan)式(shi)(shi)(shi)電(dian)(dian)(dian)(dian)除(chu)塵(chen)器(qi)(qi)的(de)(de)(de)收(shou)塵(chen)原(yuan)理相同，都是靠高(gao)壓(ya)電(dian)(dian)(dian)(dian)暈放(fang)電(dian)(dian)(dian)(dian)使得粉(fen)塵(chen)荷(he)電(dian)(dian)(dian)(dian)，荷(he)電(dian)(dian)(dian)(dian)后(hou)的(de)(de)(de)粉(fen)塵(chen)在電(dian)(dian)(dian)(dian)場(chang)力的(de)(de)(de)作用(yong)下到達(da)集塵(chen)板/管(guan)。干(gan)式(shi)(shi)(shi)電(dian)(dian)(dian)(dian)收(shou)塵(chen)器(qi)(qi)主要處理含水(shui)很低的(de)(de)(de)干(gan)氣體(ti)，濕(shi)式(shi)(shi)(shi)電(dian)(dian)(dian)(dian)除(chu)塵(chen)器(qi)(qi)主要處理含水(shui)較高(gao)乃至飽和的(de)(de)(de)濕(shi)氣體(ti)。在對集塵(chen)板/管(guan)上(shang)捕集到的(de)(de)(de)粉(fen)塵(chen)清除(chu)方式(shi)(shi)(shi)上(shang)WESP與DESP有較大區別，干(gan)式(shi)(shi)(shi)電(dian)(dian)(dian)(dian)除(chu)塵(chen)器(qi)(qi)一般采用(yong)機(ji)械振打或聲波清灰等方式(shi)(shi)(shi)清除(chu)電(dian)(dian)(dian)(dian)極上(shang)的(de)(de)(de)積灰，而(er)濕(shi)式(shi)(shi)(shi)電(dian)(dian)(dian)(dian)除(chu)塵(chen)器(qi)(qi)則采用(yong)定期沖洗的(de)(de)(de)方式(shi)(shi)(shi)，使粉(fen)塵(chen)隨著沖刷液的(de)(de)(de)流動而(er)清除(chu)。
