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)(dian)除塵器(qi)主要有(you)兩種結構形式，一種是使用(yong)耐(nai)腐蝕導電(dian)(dian)材料（可以為導電(dian)(dian)性(xing)能優良的的非(fei)金屬(shu)材料或具(ju)有(you)耐(nai)腐蝕特性(xing)的金屬(shu)材料）做集塵極，另一種是用(yong)通過(guo)噴水(shui)(shui)或溢流水(shui)(shui)形成導電(dian)(dian)水(shui)(shui)膜，利用(yong)不導電(dian)(dian)的非(fei)金屬(shu)材料做集塵極。

收塵(chen)原理(li)

濕式(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器(qi)和與(yu)干(gan)(gan)式(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器(qi)的收塵(chen)(chen)(chen)原理相同，都是(shi)靠(kao)高壓電(dian)(dian)(dian)暈放電(dian)(dian)(dian)使得(de)粉塵(chen)(chen)(chen)荷電(dian)(dian)(dian)，荷電(dian)(dian)(dian)后的粉塵(chen)(chen)(chen)在電(dian)(dian)(dian)場力的作用(yong)下(xia)到(dao)達集塵(chen)(chen)(chen)板/管。干(gan)(gan)式(shi)(shi)電(dian)(dian)(dian)收塵(chen)(chen)(chen)器(qi)主要處理含水很低的干(gan)(gan)氣(qi)體，濕式(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器(qi)主要處理含水較(jiao)高乃(nai)至飽和的濕氣(qi)體。在對集塵(chen)(chen)(chen)板/管上(shang)捕集到(dao)的粉塵(chen)(chen)(chen)清除(chu)(chu)方式(shi)(shi)上(shang)WESP與(yu)DESP有較(jiao)大區別(bie)，干(gan)(gan)式(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器(qi)一般(ban)采(cai)用(yong)機械(xie)振(zhen)打或(huo)聲波清灰(hui)等方式(shi)(shi)清除(chu)(chu)電(dian)(dian)(dian)極上(shang)的積灰(hui)，而濕式(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)器(qi)則(ze)采(cai)用(yong)定期沖洗的方式(shi)(shi)，使粉塵(chen)(chen)(chen)隨著沖刷液的流動而清除(chu)(chu)。
