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。

濕式電除(chu)塵器主(zhu)要有兩種結(jie)構形(xing)式，一種是使用(yong)耐腐蝕導電材(cai)(cai)料(liao)（可(ke)以(yi)為(wei)導電性(xing)能優良的(de)的(de)非金屬材(cai)(cai)料(liao)或具有耐腐蝕特性(xing)的(de)金屬材(cai)(cai)料(liao)）做(zuo)集塵極，另一種是用(yong)通過噴(pen)水或溢流水形(xing)成(cheng)導電水膜，利用(yong)不(bu)導電的(de)非金屬材(cai)(cai)料(liao)做(zuo)集塵極。

收塵(chen)原理

濕(shi)(shi)(shi)式(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)器(qi)(qi)和(he)與干(gan)式(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)器(qi)(qi)的收塵(chen)(chen)(chen)(chen)(chen)原理(li)相同，都是靠高壓電(dian)(dian)(dian)暈放電(dian)(dian)(dian)使(shi)得(de)粉(fen)(fen)塵(chen)(chen)(chen)(chen)(chen)荷(he)(he)電(dian)(dian)(dian)，荷(he)(he)電(dian)(dian)(dian)后的粉(fen)(fen)塵(chen)(chen)(chen)(chen)(chen)在電(dian)(dian)(dian)場力的作用(yong)下到達集(ji)塵(chen)(chen)(chen)(chen)(chen)板(ban)/管。干(gan)式(shi)(shi)電(dian)(dian)(dian)收塵(chen)(chen)(chen)(chen)(chen)器(qi)(qi)主(zhu)(zhu)要處(chu)理(li)含(han)水很低的干(gan)氣體(ti)(ti)(ti)，濕(shi)(shi)(shi)式(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)器(qi)(qi)主(zhu)(zhu)要處(chu)理(li)含(han)水較高乃至飽和(he)的濕(shi)(shi)(shi)氣體(ti)(ti)(ti)。在對集(ji)塵(chen)(chen)(chen)(chen)(chen)板(ban)/管上(shang)捕集(ji)到的粉(fen)(fen)塵(chen)(chen)(chen)(chen)(chen)清(qing)除(chu)(chu)(chu)(chu)方式(shi)(shi)上(shang)WESP與DESP有較大區別，干(gan)式(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)器(qi)(qi)一般采用(yong)機械振打或聲波清(qing)灰等(deng)方式(shi)(shi)清(qing)除(chu)(chu)(chu)(chu)電(dian)(dian)(dian)極(ji)上(shang)的積灰，而(er)濕(shi)(shi)(shi)式(shi)(shi)電(dian)(dian)(dian)除(chu)(chu)(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)器(qi)(qi)則采用(yong)定期沖(chong)(chong)洗的方式(shi)(shi)，使(shi)粉(fen)(fen)塵(chen)(chen)(chen)(chen)(chen)隨著沖(chong)(chong)刷液的流動而(er)清(qing)除(chu)(chu)(chu)(chu)。
