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)(zhong)結(jie)構形式，一(yi)種(zhong)(zhong)是(shi)使(shi)用(yong)耐腐蝕(shi)導(dao)電(dian)(dian)材料(liao)(liao)(liao)(liao)（可以為導(dao)電(dian)(dian)性(xing)能優良的(de)的(de)非金(jin)屬材料(liao)(liao)(liao)(liao)或具有(you)耐腐蝕(shi)特(te)性(xing)的(de)金(jin)屬材料(liao)(liao)(liao)(liao)）做(zuo)集塵(chen)極，另一(yi)種(zhong)(zhong)是(shi)用(yong)通過噴水(shui)或溢流水(shui)形成導(dao)電(dian)(dian)水(shui)膜(mo)，利用(yong)不導(dao)電(dian)(dian)的(de)非金(jin)屬材料(liao)(liao)(liao)(liao)做(zuo)集塵(chen)極。

收塵原(yuan)理

濕(shi)(shi)(shi)式(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)和與(yu)干式(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)的(de)(de)收塵(chen)(chen)(chen)原理相同，都(dou)是靠(kao)高(gao)壓電(dian)(dian)(dian)暈(yun)放(fang)電(dian)(dian)(dian)使得(de)粉塵(chen)(chen)(chen)荷電(dian)(dian)(dian)，荷電(dian)(dian)(dian)后(hou)的(de)(de)粉塵(chen)(chen)(chen)在電(dian)(dian)(dian)場(chang)力的(de)(de)作(zuo)用下到達集塵(chen)(chen)(chen)板/管。干式(shi)電(dian)(dian)(dian)收塵(chen)(chen)(chen)器(qi)主(zhu)(zhu)要處理含水(shui)很低的(de)(de)干氣(qi)體，濕(shi)(shi)(shi)式(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)主(zhu)(zhu)要處理含水(shui)較高(gao)乃至飽和的(de)(de)濕(shi)(shi)(shi)氣(qi)體。在對集塵(chen)(chen)(chen)板/管上(shang)捕集到的(de)(de)粉塵(chen)(chen)(chen)清除(chu)方式(shi)上(shang)WESP與(yu)DESP有較大區別，干式(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)一般采用機械振(zhen)打或(huo)聲波清灰等(deng)方式(shi)清除(chu)電(dian)(dian)(dian)極上(shang)的(de)(de)積灰，而濕(shi)(shi)(shi)式(shi)電(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)器(qi)則采用定(ding)期沖(chong)洗的(de)(de)方式(shi)，使粉塵(chen)(chen)(chen)隨著沖(chong)刷液的(de)(de)流動而清除(chu)。
