臥式電(dian)除塵(chen)器(qi)是靜電(dian)除塵(chen)器(qi)的一種,是按氣(qi)流方向(xiang)來定義的。
工作原理:當(dang)含(han)塵(chen)(chen)氣(qi)體(ti)(ti)(ti)進入除塵(chen)(chen)器入口時,含(han)塵(chen)(chen)氣(qi)體(ti)(ti)(ti)在(zai)(zai)氣(qi)流(liu)分(fen)布板以(yi)及折流(liu)板的(de)均(jun)(jun)化下(xia),氣(qi)流(liu)均(jun)(jun)勻向電(dian)(dian)(dian)(dian)(dian)(dian)場邁進,在(zai)(zai)入口橫(heng)斷面擴大(da)的(de)作用下(xia),氣(qi)流(liu)速度迅速降低,其(qi)中一些較重的(de)塵(chen)(chen)粒便失去速度而沉(chen)(chen)降下(xia)來。進入電(dian)(dian)(dian)(dian)(dian)(dian)場的(de)含(han)塵(chen)(chen)氣(qi)體(ti)(ti)(ti)由于電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)通(tong)(tong)(tong)入高壓直流(liu)電(dian)(dian)(dian)(dian)(dian)(dian),則(ze)在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)附(fu)(fu)近產生(sheng)電(dian)(dian)(dian)(dian)(dian)(dian)暈(yun)現象,使氣(qi)體(ti)(ti)(ti)電(dian)(dian)(dian)(dian)(dian)(dian)離,電(dian)(dian)(dian)(dian)(dian)(dian)離后(hou)的(de)氣(qi)體(ti)(ti)(ti)中存在(zai)(zai)大(da)量的(de)電(dian)(dian)(dian)(dian)(dian)(dian)子和離子,使粉塵(chen)(chen)帶(dai)有電(dian)(dian)(dian)(dian)(dian)(dian)子同時使其(qi)吸附(fu)(fu)在(zai)(zai)陰極(ji)板上。后(hou)通(tong)(tong)(tong)過(guo)(guo)設備陰陽(yang)極(ji)振(zhen)打系統(tong)的(de)振(zhen)打,使沉(chen)(chen)積在(zai)(zai)陰陽(yang)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上的(de)粉塵(chen)(chen)振(zhen)落,進入集灰(hui)斗通(tong)(tong)(tong)過(guo)(guo)排(pai)灰(hui)裝置排(pai)出。
要想讓(rang)含(han)塵氣體(ti)(ti)更為均(jun)勻(yun)地進入(ru)到電(dian)場當中,所以在臥式(shi)電(dian)除塵器當中,在進入(ru)設備時(shi)內按(an)需設置(zhi)一至三道氣流(liu)分(fen)布板和導流(liu)板,這樣(yang)可以讓(rang)氣流(liu)分(fen)布更為均(jun)勻(yun),從而實現(xian)良(liang)好的效(xiao)果,并且還不容易出現(xian)堵孔等問題。
臥式電除(chu)塵(chen)器優勢
(1)初(chu)期除塵效率能達到99%,能捕(bu)集1um以下的細微粉塵,但從經濟方(fang)面考慮(lv),一般控制一個合(he)理(li)的除塵效率。
(2)處理煙(yan)氣量大,可用于(yu)高溫(可高達500℃)、高壓和高濕(相對濕度可達100%)的場合(he),能連續(xu)運轉,并(bing)能實(shi)現自動化。
(3)具有低阻的特點,電除塵器壓力損(sun)失僅200~500Pa。
(4)靜(jing)電(dian)除(chu)塵器(qi)運行(xing)費(fei)用(yong)低 , 靜(jing)電(dian)除(chu)塵器(qi)運行(xing)穩定, 故障率極(ji)低;
應用(yong)范圍
對(dui)酸霧(wu)、有(you)毒重金屬(shu)以及PM10,尤其(qi)是PM2.5的(de)(de)微細粉(fen)塵有(you)良(liang)好的(de)(de)聯合脫除(chu)效果,對(dui)于(yu)減(jian)(jian)少(shao)燃(ran)煤鍋爐、鋼鐵燒結機(ji)、玻(bo)璃(li)爐窯(yao)、煤炭化等(deng)多行業(ye)的(de)(de)粉(fen)塵排放量,減(jian)(jian)少(shao)大氣(qi)(qi)污染,減(jian)(jian)低(di)霧(wu)霾天(tian)氣(qi)(qi)機(ji)率(lv),具有(you)良(liang)好的(de)(de)效果。適用于(yu)電廠(chang)燃(ran)煤鍋爐、有(you)色治金爐窯(yao)、玻(bo)璃(li)生(sheng)產(chan)爐窯(yao)、水泥(ni)生(sheng)產(chan)爐窯(yao)、化工生(sheng)產(chan)線、紡織生(sheng)產(chan)線、及其(qi)它行業(ye)等(deng)經(jing)脫硫、脫硝后含PM2.5、氣(qi)(qi)溶膠(jiao)、酸霧(wu)霧(wu)滴煙氣(qi)(qi)的(de)(de)處理。
