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(chen)(chen)器(qi)主要有(you)兩(liang)種(zhong)(zhong)結(jie)構(gou)形(xing)式，一種(zhong)(zhong)是(shi)使用(yong)(yong)(yong)耐腐蝕(shi)(shi)導(dao)電(dian)材(cai)料(liao)(liao)（可以為導(dao)電(dian)性能優良的(de)的(de)非(fei)金屬材(cai)料(liao)(liao)或具(ju)有(you)耐腐蝕(shi)(shi)特性的(de)金屬材(cai)料(liao)(liao)）做集塵(chen)(chen)極，另一種(zhong)(zhong)是(shi)用(yong)(yong)(yong)通過(guo)噴(pen)水或溢流水形(xing)成導(dao)電(dian)水膜，利用(yong)(yong)(yong)不導(dao)電(dian)的(de)非(fei)金屬材(cai)料(liao)(liao)做集塵(chen)(chen)極。

收塵(chen)原理(li)

濕式電(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)器(qi)(qi)和與干(gan)式電(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)器(qi)(qi)的(de)(de)收(shou)塵(chen)(chen)(chen)(chen)原理相同，都是靠高壓電(dian)(dian)(dian)(dian)暈放電(dian)(dian)(dian)(dian)使得粉(fen)(fen)塵(chen)(chen)(chen)(chen)荷電(dian)(dian)(dian)(dian)，荷電(dian)(dian)(dian)(dian)后的(de)(de)粉(fen)(fen)塵(chen)(chen)(chen)(chen)在(zai)電(dian)(dian)(dian)(dian)場力的(de)(de)作(zuo)用(yong)下(xia)到達(da)集塵(chen)(chen)(chen)(chen)板/管。干(gan)式電(dian)(dian)(dian)(dian)收(shou)塵(chen)(chen)(chen)(chen)器(qi)(qi)主(zhu)要(yao)(yao)處理含水(shui)很低的(de)(de)干(gan)氣(qi)體，濕式電(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)器(qi)(qi)主(zhu)要(yao)(yao)處理含水(shui)較高乃(nai)至飽和的(de)(de)濕氣(qi)體。在(zai)對集塵(chen)(chen)(chen)(chen)板/管上捕集到的(de)(de)粉(fen)(fen)塵(chen)(chen)(chen)(chen)清(qing)除方式上WESP與DESP有(you)較大區(qu)別，干(gan)式電(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)器(qi)(qi)一般采用(yong)機械振打(da)或聲波清(qing)灰等方式清(qing)除電(dian)(dian)(dian)(dian)極上的(de)(de)積灰，而濕式電(dian)(dian)(dian)(dian)除塵(chen)(chen)(chen)(chen)器(qi)(qi)則(ze)采用(yong)定期沖(chong)洗的(de)(de)方式，使粉(fen)(fen)塵(chen)(chen)(chen)(chen)隨著沖(chong)刷液的(de)(de)流(liu)動而清(qing)除。
