臥式電除塵器(qi)是(shi)靜(jing)電除塵器(qi)的一種,是(shi)按氣流(liu)方向(xiang)來定義的。
工作原(yuan)理:當含塵(chen)(chen)(chen)氣(qi)(qi)體進入(ru)(ru)(ru)除塵(chen)(chen)(chen)器入(ru)(ru)(ru)口時(shi),含塵(chen)(chen)(chen)氣(qi)(qi)體在(zai)氣(qi)(qi)流分布板以(yi)及折流板的(de)均(jun)化下,氣(qi)(qi)流均(jun)勻向電(dian)(dian)(dian)(dian)(dian)場邁進,在(zai)入(ru)(ru)(ru)口橫斷(duan)面擴大的(de)作用下,氣(qi)(qi)流速(su)(su)度迅速(su)(su)降低,其中一(yi)些(xie)較重的(de)塵(chen)(chen)(chen)粒便(bian)失(shi)去(qu)速(su)(su)度而沉降下來。進入(ru)(ru)(ru)電(dian)(dian)(dian)(dian)(dian)場的(de)含塵(chen)(chen)(chen)氣(qi)(qi)體由(you)于(yu)電(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)極(ji)通(tong)入(ru)(ru)(ru)高壓直流電(dian)(dian)(dian)(dian)(dian),則在(zai)電(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)極(ji)附近產生(sheng)電(dian)(dian)(dian)(dian)(dian)暈(yun)(yun)現象,使(shi)氣(qi)(qi)體電(dian)(dian)(dian)(dian)(dian)離,電(dian)(dian)(dian)(dian)(dian)離后的(de)氣(qi)(qi)體中存在(zai)大量(liang)的(de)電(dian)(dian)(dian)(dian)(dian)子和離子,使(shi)粉塵(chen)(chen)(chen)帶有(you)電(dian)(dian)(dian)(dian)(dian)子同時(shi)使(shi)其吸附在(zai)陰極(ji)板上。后通(tong)過(guo)設備(bei)陰陽極(ji)振(zhen)(zhen)打系統的(de)振(zhen)(zhen)打,使(shi)沉積在(zai)陰陽電(dian)(dian)(dian)(dian)(dian)極(ji)上的(de)粉塵(chen)(chen)(chen)振(zhen)(zhen)落,進入(ru)(ru)(ru)集灰斗通(tong)過(guo)排(pai)灰裝置排(pai)出。
要想讓含塵氣(qi)(qi)體更為(wei)均勻地進入到電場(chang)當(dang)中,所以在(zai)臥式(shi)電除塵器(qi)當(dang)中,在(zai)進入設備時內按需設置一(yi)至三道氣(qi)(qi)流(liu)分(fen)布(bu)板(ban)和導流(liu)板(ban),這樣(yang)可以讓氣(qi)(qi)流(liu)分(fen)布(bu)更為(wei)均勻,從(cong)而實現良(liang)好的效果,并且還(huan)不容(rong)易出現堵孔(kong)等問(wen)題。
臥(wo)式電除塵器優勢
(1)初期除(chu)塵效(xiao)(xiao)率(lv)能達到99%,能捕集(ji)1um以下的(de)細微粉塵,但(dan)從經濟方面考慮(lv),一(yi)般(ban)控(kong)制一(yi)個(ge)合理的(de)除(chu)塵效(xiao)(xiao)率(lv)。
(2)處(chu)理煙氣量大(da),可用于高(gao)(gao)溫(可高(gao)(gao)達500℃)、高(gao)(gao)壓(ya)和高(gao)(gao)濕(相對濕度可達100%)的場合,能(neng)連續(xu)運(yun)轉,并能(neng)實現自(zi)動化(hua)。
(3)具(ju)有(you)低阻的特點,電(dian)除塵器(qi)壓力損失(shi)僅(jin)200~500Pa。
(4)靜(jing)電(dian)除(chu)塵器(qi)運行(xing)費用(yong)低 , 靜(jing)電(dian)除(chu)塵器(qi)運行(xing)穩(wen)定, 故障(zhang)率極低;
應用范(fan)圍
對酸(suan)霧、有毒重(zhong)金(jin)屬(shu)以及(ji)PM10,尤其(qi)是PM2.5的微(wei)細粉(fen)(fen)塵(chen)有良好(hao)的聯合(he)脫除(chu)效果,對于減(jian)少燃煤鍋爐(lu)、鋼鐵燒結機(ji)、玻璃爐(lu)窯、煤炭化等多行(xing)業的粉(fen)(fen)塵(chen)排放(fang)量(liang),減(jian)少大氣(qi)污染,減(jian)低霧霾天氣(qi)機(ji)率(lv),具有良好(hao)的效果。適用于電廠燃煤鍋爐(lu)、有色(se)治金(jin)爐(lu)窯、玻璃生(sheng)產爐(lu)窯、水泥(ni)生(sheng)產爐(lu)窯、化工生(sheng)產線(xian)、紡織生(sheng)產線(xian)、及(ji)其(qi)它(ta)行(xing)業等經脫硫、脫硝后含PM2.5、氣(qi)溶膠(jiao)、酸(suan)霧霧滴煙(yan)氣(qi)的處理。
