臥式電除塵(chen)器是(shi)靜電除塵(chen)器的一種,是(shi)按氣流方(fang)向來(lai)定(ding)義的。
工(gong)作(zuo)原理:當含塵(chen)(chen)氣(qi)體(ti)(ti)(ti)進入(ru)除塵(chen)(chen)器入(ru)口時(shi),含塵(chen)(chen)氣(qi)體(ti)(ti)(ti)在(zai)氣(qi)流(liu)分(fen)布板以及折(zhe)流(liu)板的均化下,氣(qi)流(liu)均勻(yun)向(xiang)電(dian)(dian)(dian)(dian)(dian)場邁進,在(zai)入(ru)口橫斷(duan)面擴大的作(zuo)用下,氣(qi)流(liu)速度迅速降低(di),其(qi)中(zhong)一些較(jiao)重的塵(chen)(chen)粒便失去(qu)速度而(er)沉降下來。進入(ru)電(dian)(dian)(dian)(dian)(dian)場的含塵(chen)(chen)氣(qi)體(ti)(ti)(ti)由于電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)通(tong)(tong)入(ru)高壓直流(liu)電(dian)(dian)(dian)(dian)(dian),則在(zai)電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)附近產生電(dian)(dian)(dian)(dian)(dian)暈(yun)現象(xiang),使(shi)(shi)氣(qi)體(ti)(ti)(ti)電(dian)(dian)(dian)(dian)(dian)離(li),電(dian)(dian)(dian)(dian)(dian)離(li)后(hou)(hou)的氣(qi)體(ti)(ti)(ti)中(zhong)存(cun)在(zai)大量的電(dian)(dian)(dian)(dian)(dian)子和離(li)子,使(shi)(shi)粉(fen)塵(chen)(chen)帶有電(dian)(dian)(dian)(dian)(dian)子同時(shi)使(shi)(shi)其(qi)吸(xi)附在(zai)陰極(ji)板上。后(hou)(hou)通(tong)(tong)過設備陰陽極(ji)振(zhen)打系統的振(zhen)打,使(shi)(shi)沉積(ji)在(zai)陰陽電(dian)(dian)(dian)(dian)(dian)極(ji)上的粉(fen)塵(chen)(chen)振(zhen)落(luo),進入(ru)集灰(hui)斗通(tong)(tong)過排(pai)灰(hui)裝置排(pai)出。
要想讓(rang)含塵(chen)氣體更(geng)為均(jun)勻地進(jin)(jin)入(ru)到電(dian)場當中,所以(yi)在臥式電(dian)除(chu)塵(chen)器當中,在進(jin)(jin)入(ru)設備時內按(an)需設置(zhi)一至三道氣流分布(bu)板和導流板,這樣可以(yi)讓(rang)氣流分布(bu)更(geng)為均(jun)勻,從(cong)而實現良好的效果,并(bing)且(qie)還不容易出現堵孔等問題。
臥式電(dian)除塵器優(you)勢(shi)
(1)初期除(chu)塵效率能達到99%,能捕集1um以下的(de)細(xi)微粉塵,但從(cong)經濟方(fang)面考慮,一般控制一個(ge)合理的(de)除(chu)塵效率。
(2)處理(li)煙(yan)氣量大,可(ke)用(yong)于高溫(可(ke)高達500℃)、高壓和(he)高濕(shi)(相對濕(shi)度可(ke)達100%)的(de)場合(he),能(neng)連續運轉,并能(neng)實現自動(dong)化。
(3)具有低(di)阻的特點,電除(chu)塵器壓力損失僅(jin)200~500Pa。
(4)靜電除塵(chen)(chen)器運行費用低 , 靜電除塵(chen)(chen)器運行穩定, 故障率極低;
應用(yong)范圍
對(dui)酸霧、有(you)毒重金(jin)屬以及(ji)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(tuo)除效(xiao)果,對(dui)于減(jian)少(shao)燃煤(mei)(mei)鍋爐(lu)(lu)(lu)、鋼鐵燒結(jie)機、玻(bo)璃(li)爐(lu)(lu)(lu)窯、煤(mei)(mei)炭化等多行業的(de)(de)粉(fen)塵排放(fang)量,減(jian)少(shao)大(da)氣(qi)(qi)污染,減(jian)低霧霾(mai)天氣(qi)(qi)機率(lv),具有(you)良(liang)好的(de)(de)效(xiao)果。適用(yong)于電廠燃煤(mei)(mei)鍋爐(lu)(lu)(lu)、有(you)色治金(jin)爐(lu)(lu)(lu)窯、玻(bo)璃(li)生產爐(lu)(lu)(lu)窯、水泥生產爐(lu)(lu)(lu)窯、化工生產線(xian)、紡織生產線(xian)、及(ji)其(qi)它行業等經脫(tuo)硫、脫(tuo)硝后含PM2.5、氣(qi)(qi)溶膠、酸霧霧滴煙氣(qi)(qi)的(de)(de)處理(li)。
