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。

濕式電除塵(chen)器主要有(you)(you)兩(liang)種(zhong)結構形式，一種(zhong)是使(shi)用耐腐(fu)蝕導電材(cai)料（可以為(wei)導電性(xing)能(neng)優良的的非金(jin)屬(shu)材(cai)料或(huo)具有(you)(you)耐腐(fu)蝕特性(xing)的金(jin)屬(shu)材(cai)料）做集塵(chen)極(ji)，另(ling)一種(zhong)是用通(tong)過噴水或(huo)溢流水形成(cheng)導電水膜，利用不導電的非金(jin)屬(shu)材(cai)料做集塵(chen)極(ji)。

收塵(chen)原理

濕(shi)式(shi)(shi)電(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)器(qi)和與(yu)干式(shi)(shi)電(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)器(qi)的(de)(de)(de)收(shou)塵(chen)(chen)原(yuan)理(li)相同，都是靠高壓電(dian)(dian)(dian)(dian)(dian)暈放電(dian)(dian)(dian)(dian)(dian)使得粉(fen)塵(chen)(chen)荷電(dian)(dian)(dian)(dian)(dian)，荷電(dian)(dian)(dian)(dian)(dian)后的(de)(de)(de)粉(fen)塵(chen)(chen)在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)場力的(de)(de)(de)作用(yong)下(xia)到達(da)集塵(chen)(chen)板/管。干式(shi)(shi)電(dian)(dian)(dian)(dian)(dian)收(shou)塵(chen)(chen)器(qi)主(zhu)要處理(li)含(han)水很(hen)低的(de)(de)(de)干氣(qi)體，濕(shi)式(shi)(shi)電(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)器(qi)主(zhu)要處理(li)含(han)水較高乃至(zhi)飽和的(de)(de)(de)濕(shi)氣(qi)體。在(zai)(zai)對集塵(chen)(chen)板/管上(shang)捕集到的(de)(de)(de)粉(fen)塵(chen)(chen)清除方式(shi)(shi)上(shang)WESP與(yu)DESP有較大區別，干式(shi)(shi)電(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)器(qi)一般采用(yong)機(ji)械振打(da)或聲(sheng)波清灰等方式(shi)(shi)清除電(dian)(dian)(dian)(dian)(dian)極上(shang)的(de)(de)(de)積灰，而濕(shi)式(shi)(shi)電(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)器(qi)則采用(yong)定期沖洗的(de)(de)(de)方式(shi)(shi)，使粉(fen)塵(chen)(chen)隨(sui)著沖刷(shua)液的(de)(de)(de)流動(dong)而清除。
