濕式(shi)靜電(dian)除塵器(qi)也是一種靜電(dian)除塵器(qi)。濕式(shi)靜電(dian)除塵器(qi)由除塵器(qi)系(xi)統(tong)(tong)和供電(dian)設備自動控制(zhi)系(xi)統(tong)(tong)兩部分組成。今天，國昌環保就來介紹濕式(shi)靜電(dian)除塵器(qi)工作原理和優勢。

　　濕式靜電除(chu)塵器工作原理

　　濕(shi)式電(dian)(dian)(dian)(dian)(dian)(dian)(dian)除塵器是一(yi)種利用(yong)強電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)(chang)將固體(ti)和(he)液體(ti)懸浮(fu)顆(ke)粒與氣(qi)體(ti)分離的氣(qi)體(ti)凈化系統。在(zai)(zai)(zai)(zai)其電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極系統中通(tong)(tong)過(guo)高壓直流電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，在(zai)(zai)(zai)(zai)極間產生強電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)(chang)，使(shi)周圍(wei)氣(qi)體(ti)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)離，產生大量(liang)的電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)和(he)正負離子(zi)。當粉塵、煙霧(wu)(wu)和(he)水霧(wu)(wu)進入(ru)(ru)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)(chang)時(shi)，粉塵和(he)細(xi)液體(ti)在(zai)(zai)(zai)(zai)這些電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)和(he)離子(zi)的作用(yong)下，會以極快(kuai)的速度(du)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，并在(zai)(zai)(zai)(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)(chang)力的作用(yong)下迅速傾向于相反極性的電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極，最終釋放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)荷并吸附在(zai)(zai)(zai)(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極上。由于濕(shi)法(fa)脫硫過(guo)程中產生的水霧(wu)(wu)，粉塵凝結(jie)、加濕(shi)，粉塵和(he)水霧(wu)(wu)在(zai)(zai)(zai)(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)(chang)中充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，一(yi)起收集，水霧(wu)(wu)在(zai)(zai)(zai)(zai)粉塵板(ban)上產生水膜，水膜保持電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極安靜(jing)。噴(pen)(pen)霧(wu)(wu)清洗裝置噴(pen)(pen)出一(yi)定壓力的水霧(wu)(wu)，噴(pen)(pen)入(ru)(ru)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極表(biao)面，加速粉塵液沿陰陰電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極表(biao)面流入(ru)(ru)料倉(cang)，最后排(pai)沉沙池(chi)池(chi)，凈化氣(qi)體(ti)通(tong)(tong)過(guo)排(pai)氣(qi)口(kou)排(pai)入(ru)(ru)大氣(qi)。

　　濕式電除(chu)塵器的(de)基(ji)本工作過程主要(yao)分為(wei)三個階段：①粉塵顆粒(li)和(he)水霧顆粒(li)進入電除(chu)塵器充(chong)電;②移(yi)動和(he)沉積荷(he)電塵粒(li)和(he)液體;③噴淋清(qing)洗裝置(zhi)清(qing)洗電極表面加速(su)粉塵脫落(即除(chu)塵)。

　　濕(shi)(shi)(shi)式電(dian)除(chu)塵(chen)器(qi)的工(gong)作原理與傳統(tong)電(dian)除(chu)塵(chen)器(qi)相似，依靠靜電(dian)。區(qu)別在(zai)(zai)(zai)于工(gong)作環境(jing)是(shi)一個“濕(shi)(shi)(shi)”一“干(gan)”。干(gan)試電(dian)除(chu)塵(chen)器(qi)布置在(zai)(zai)(zai)濕(shi)(shi)(shi)法(fa)脫硫(liu)前端，濕(shi)(shi)(shi)式電(dian)除(chu)塵(chen)器(qi)處理脫硫(liu)后(hou)(hou)的濕(shi)(shi)(shi)煙(yan)塵(chen)，布置在(zai)(zai)(zai)除(chu)塵(chen)脫硫(liu)系統(tong)末端，是(shi)煙(yan)氣處理的最(zui)后(hou)(hou)守門(men)員(yuan)。

　　二、濕式(shi)靜電除塵器(qi)的優勢

　　①除塵效率高;

　　選擇噴(pen)水清洗電極表面(mian)粉(fen)塵(chen)(chen)，無二(er)次粉(fen)塵(chen)(chen)，顯著降(jiang)低(di)出口(kou)粉(fen)塵(chen)(chen)排放濃(nong)度(du)，保證除(chu)塵(chen)(chen)器出口(kou)粉(fen)塵(chen)(chen)排放濃(nong)度(du)為10mg/Nm3。

　　②除灰質量穩定;

　　濕法脫硫工藝后(hou)續煙(yan)塵(chen)中(zhong)含有一(yi)(yi)定量(liang)的水霧。收集到電極表面(mian)可(ke)使電極表面(mian)始(shi)終保(bao)(bao)持(chi)一(yi)(yi)定厚度的水膜，有利于煙(yan)塵(chen)中(zhong)的灰塵(chen)和液體流向料倉;噴(pen)(pen)淋清洗系統(tong)的噴(pen)(pen)淋清洗可(ke)以保(bao)(bao)持(chi)電極表面(mian)安靜(jing)，保(bao)(bao)證除塵(chen)器能夠長期順利排放(fang)。

　　③高于電阻粉塵的收集能力;

　　電場用(yong)水噴灑清洗(xi)，水顆(ke)粒(li)附(fu)著在粉(fen)塵(chen)(chen)表(biao)面，特別是高比電阻粉(fen)塵(chen)(chen)顆(ke)粒(li)附(fu)著在水顆(ke)粒(li)表(biao)面，加速粉(fen)塵(chen)(chen)顆(ke)粒(li)在粉(fen)塵(chen)(chen)中的異常速度，有(you)效處理高比電阻粉(fen)塵(chen)(chen)的收集問題。

　　④PM2.5微(wei)粉塵(chen)和氣(qi)溶膠去除(chu)效率高(gao);

　　通過收集(ji)濕式電除(chu)塵(chen)器，可以收集(ji)濕式脫(tuo)硫(liu)工藝后續煙(yan)塵(chen)中的煙(yan)塵(chen)PM2.5微粉塵(chen)和氣溶膠，去除(chu)率>90%，提(ti)高(gao)煙(yan)塵(chen)排放透明度，滿足我國空氣質量(liang)控制(zhi)要(yao)求。

　　⑤處理濕(shi)法脫(tuo)硫(liu)引起的石膏雨、藍煙酸霧環(huan)境(jing)問(wen)題;

　　脫硫塔對SO3和(he)水(shui)霧的(de)(de)去除率很(hen)低，SO3以氣溶膠的(de)(de)形式(shi)隨水(shui)霧和(he)煙(yan)(yan)塵排出，導(dao)致(zhi)煙(yan)(yan)管風(feng)向下(xia)游經常出現(xian)“霧霾”，“石膏雨”等現(xian)象，或長煙(yan)(yan)尾“藍煙(yan)(yan)”現(xian)象。濕式(shi)電除塵器能有效解決上述問題(ti)，其中SO3的(de)(de)去除率>90%，水(shui)霧去除率>75%。

　　⑥煙塵中汞和重(zhong)金屬去除效率高(gao);

　　濕(shi)式(shi)電除塵器采(cai)(cai)用(yong)，可采(cai)(cai)集濕(shi)式(shi)脫硫后續煙塵中的汞及重金屬，其去除率>90%。
