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)(dian)除塵(chen)器主要有兩種結構(gou)形式，一種是使用耐腐(fu)蝕(shi)導電(dian)(dian)材(cai)(cai)料(liao)（可以為(wei)導電(dian)(dian)性(xing)能優良的(de)的(de)非金(jin)屬(shu)材(cai)(cai)料(liao)或具有耐腐(fu)蝕(shi)特性(xing)的(de)金(jin)屬(shu)材(cai)(cai)料(liao)）做集(ji)塵(chen)極，另一種是用通過噴水(shui)或溢流水(shui)形成(cheng)導電(dian)(dian)水(shui)膜，利用不(bu)導電(dian)(dian)的(de)非金(jin)屬(shu)材(cai)(cai)料(liao)做集(ji)塵(chen)極。

收塵原理

濕式(shi)(shi)(shi)電(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)器(qi)(qi)(qi)和與干(gan)(gan)式(shi)(shi)(shi)電(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)器(qi)(qi)(qi)的(de)收(shou)塵(chen)(chen)(chen)(chen)(chen)原理相同，都(dou)是靠(kao)高(gao)壓電(dian)(dian)暈放電(dian)(dian)使得(de)粉(fen)(fen)塵(chen)(chen)(chen)(chen)(chen)荷電(dian)(dian)，荷電(dian)(dian)后的(de)粉(fen)(fen)塵(chen)(chen)(chen)(chen)(chen)在電(dian)(dian)場力的(de)作(zuo)用(yong)下(xia)到達集(ji)塵(chen)(chen)(chen)(chen)(chen)板/管。干(gan)(gan)式(shi)(shi)(shi)電(dian)(dian)收(shou)塵(chen)(chen)(chen)(chen)(chen)器(qi)(qi)(qi)主要處理含水(shui)很低(di)的(de)干(gan)(gan)氣(qi)體，濕式(shi)(shi)(shi)電(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)器(qi)(qi)(qi)主要處理含水(shui)較高(gao)乃至飽和的(de)濕氣(qi)體。在對集(ji)塵(chen)(chen)(chen)(chen)(chen)板/管上(shang)捕集(ji)到的(de)粉(fen)(fen)塵(chen)(chen)(chen)(chen)(chen)清除(chu)(chu)方式(shi)(shi)(shi)上(shang)WESP與DESP有(you)較大區別(bie)，干(gan)(gan)式(shi)(shi)(shi)電(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)器(qi)(qi)(qi)一般(ban)采(cai)用(yong)機械振打或(huo)聲波清灰(hui)等(deng)方式(shi)(shi)(shi)清除(chu)(chu)電(dian)(dian)極上(shang)的(de)積灰(hui)，而濕式(shi)(shi)(shi)電(dian)(dian)除(chu)(chu)塵(chen)(chen)(chen)(chen)(chen)器(qi)(qi)(qi)則采(cai)用(yong)定期沖洗的(de)方式(shi)(shi)(shi)，使粉(fen)(fen)塵(chen)(chen)(chen)(chen)(chen)隨著(zhu)沖刷液(ye)的(de)流動而清除(chu)(chu)。
