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)式電(dian)除(chu)塵器主要有(you)兩種(zhong)結構形(xing)式，一(yi)種(zhong)是(shi)使用(yong)耐(nai)腐蝕(shi)導(dao)(dao)電(dian)材(cai)(cai)(cai)料（可以(yi)為導(dao)(dao)電(dian)性能優良(liang)的(de)的(de)非金屬材(cai)(cai)(cai)料或具有(you)耐(nai)腐蝕(shi)特性的(de)金屬材(cai)(cai)(cai)料）做(zuo)(zuo)集塵極，另一(yi)種(zhong)是(shi)用(yong)通過噴水或溢流水形(xing)成導(dao)(dao)電(dian)水膜，利用(yong)不導(dao)(dao)電(dian)的(de)非金屬材(cai)(cai)(cai)料做(zuo)(zuo)集塵極。

收塵(chen)原理

濕(shi)式(shi)(shi)電(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器(qi)(qi)和(he)與(yu)干(gan)式(shi)(shi)電(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器(qi)(qi)的(de)收塵(chen)(chen)(chen)原理(li)(li)相同，都是靠高(gao)壓電(dian)(dian)(dian)(dian)暈放電(dian)(dian)(dian)(dian)使得粉塵(chen)(chen)(chen)荷電(dian)(dian)(dian)(dian)，荷電(dian)(dian)(dian)(dian)后的(de)粉塵(chen)(chen)(chen)在(zai)電(dian)(dian)(dian)(dian)場力的(de)作用下到達集塵(chen)(chen)(chen)板(ban)/管。干(gan)式(shi)(shi)電(dian)(dian)(dian)(dian)收塵(chen)(chen)(chen)器(qi)(qi)主要處理(li)(li)含水很低的(de)干(gan)氣(qi)體(ti)，濕(shi)式(shi)(shi)電(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器(qi)(qi)主要處理(li)(li)含水較高(gao)乃至飽和(he)的(de)濕(shi)氣(qi)體(ti)。在(zai)對集塵(chen)(chen)(chen)板(ban)/管上(shang)捕集到的(de)粉塵(chen)(chen)(chen)清(qing)除(chu)(chu)方(fang)式(shi)(shi)上(shang)WESP與(yu)DESP有較大區(qu)別，干(gan)式(shi)(shi)電(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器(qi)(qi)一(yi)般采(cai)用機械振打或(huo)聲(sheng)波清(qing)灰(hui)等方(fang)式(shi)(shi)清(qing)除(chu)(chu)電(dian)(dian)(dian)(dian)極(ji)上(shang)的(de)積灰(hui)，而濕(shi)式(shi)(shi)電(dian)(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器(qi)(qi)則采(cai)用定期(qi)沖洗的(de)方(fang)式(shi)(shi)，使粉塵(chen)(chen)(chen)隨(sui)著沖刷液的(de)流動而清(qing)除(chu)(chu)。
