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(shi)式(shi)電(dian)(dian)除塵(chen)(chen)器主(zhu)要有(you)(you)兩種結構形式(shi)，一(yi)種是使用(yong)(yong)耐腐(fu)蝕(shi)導電(dian)(dian)材(cai)(cai)料(liao)(liao)（可以為導電(dian)(dian)性能優良的(de)的(de)非金(jin)屬(shu)(shu)材(cai)(cai)料(liao)(liao)或具有(you)(you)耐腐(fu)蝕(shi)特(te)性的(de)金(jin)屬(shu)(shu)材(cai)(cai)料(liao)(liao)）做集塵(chen)(chen)極，另(ling)一(yi)種是用(yong)(yong)通過(guo)噴水或溢流(liu)水形成導電(dian)(dian)水膜，利用(yong)(yong)不導電(dian)(dian)的(de)非金(jin)屬(shu)(shu)材(cai)(cai)料(liao)(liao)做集塵(chen)(chen)極。

收塵(chen)原理

濕式(shi)(shi)電(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器(qi)(qi)(qi)和與干(gan)式(shi)(shi)電(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器(qi)(qi)(qi)的(de)(de)收塵(chen)(chen)(chen)原理相同，都是靠高壓電(dian)(dian)暈放電(dian)(dian)使得粉塵(chen)(chen)(chen)荷電(dian)(dian)，荷電(dian)(dian)后的(de)(de)粉塵(chen)(chen)(chen)在(zai)電(dian)(dian)場(chang)力的(de)(de)作用下(xia)到達集塵(chen)(chen)(chen)板(ban)(ban)/管(guan)。干(gan)式(shi)(shi)電(dian)(dian)收塵(chen)(chen)(chen)器(qi)(qi)(qi)主要處(chu)理含水很低的(de)(de)干(gan)氣(qi)(qi)體，濕式(shi)(shi)電(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器(qi)(qi)(qi)主要處(chu)理含水較高乃(nai)至飽和的(de)(de)濕氣(qi)(qi)體。在(zai)對集塵(chen)(chen)(chen)板(ban)(ban)/管(guan)上(shang)捕(bu)集到的(de)(de)粉塵(chen)(chen)(chen)清(qing)除(chu)(chu)方(fang)式(shi)(shi)上(shang)WESP與DESP有較大區別，干(gan)式(shi)(shi)電(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器(qi)(qi)(qi)一般采用機械振打或聲波清(qing)灰等方(fang)式(shi)(shi)清(qing)除(chu)(chu)電(dian)(dian)極上(shang)的(de)(de)積灰，而濕式(shi)(shi)電(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器(qi)(qi)(qi)則采用定期沖(chong)洗的(de)(de)方(fang)式(shi)(shi)，使粉塵(chen)(chen)(chen)隨著沖(chong)刷液的(de)(de)流(liu)動而清(qing)除(chu)(chu)。
