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(shi)(shi)電(dian)(dian)除塵器(qi)主要(yao)有兩種結構形式(shi)(shi)，一種是(shi)使用耐腐(fu)蝕(shi)導(dao)電(dian)(dian)材(cai)(cai)料（可(ke)以為導(dao)電(dian)(dian)性能優良的的非(fei)金(jin)屬材(cai)(cai)料或(huo)具有耐腐(fu)蝕(shi)特(te)性的金(jin)屬材(cai)(cai)料）做集塵極，另一種是(shi)用通過噴(pen)水(shui)或(huo)溢流水(shui)形成導(dao)電(dian)(dian)水(shui)膜，利用不導(dao)電(dian)(dian)的非(fei)金(jin)屬材(cai)(cai)料做集塵極。

收塵原理

濕式(shi)(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)器(qi)和(he)與(yu)干式(shi)(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)器(qi)的收塵(chen)原理(li)相同，都是靠(kao)高壓電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)使得粉(fen)(fen)塵(chen)荷電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，荷電(dian)(dian)(dian)(dian)(dian)(dian)(dian)后(hou)的粉(fen)(fen)塵(chen)在電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場力的作用(yong)(yong)下到達集塵(chen)板/管。干式(shi)(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)收塵(chen)器(qi)主(zhu)要處理(li)含水很低的干氣(qi)(qi)體，濕式(shi)(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)器(qi)主(zhu)要處理(li)含水較高乃至飽和(he)的濕氣(qi)(qi)體。在對集塵(chen)板/管上(shang)捕集到的粉(fen)(fen)塵(chen)清(qing)除(chu)(chu)(chu)方式(shi)(shi)上(shang)WESP與(yu)DESP有較大(da)區別(bie)，干式(shi)(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)器(qi)一般采用(yong)(yong)機(ji)械振打或聲波清(qing)灰等(deng)方式(shi)(shi)清(qing)除(chu)(chu)(chu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極上(shang)的積灰，而濕式(shi)(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)除(chu)(chu)(chu)塵(chen)器(qi)則(ze)采用(yong)(yong)定期沖洗的方式(shi)(shi)，使粉(fen)(fen)塵(chen)隨著沖刷液的流動而清(qing)除(chu)(chu)(chu)。
