臥式(shi)電除塵器是(shi)靜(jing)電除塵器的一種(zhong),是(shi)按氣(qi)流方向來(lai)定義的。
工作原理(li):當含(han)塵(chen)(chen)(chen)氣(qi)(qi)體(ti)進入除塵(chen)(chen)(chen)器入口時(shi),含(han)塵(chen)(chen)(chen)氣(qi)(qi)體(ti)在氣(qi)(qi)流(liu)(liu)分布(bu)板(ban)以及折流(liu)(liu)板(ban)的(de)(de)均化(hua)下,氣(qi)(qi)流(liu)(liu)均勻向電(dian)(dian)(dian)(dian)(dian)(dian)場邁進,在入口橫斷面(mian)擴大(da)的(de)(de)作用下,氣(qi)(qi)流(liu)(liu)速度(du)迅速降低,其(qi)中一些(xie)較重(zhong)的(de)(de)塵(chen)(chen)(chen)粒便(bian)失去速度(du)而(er)沉降下來。進入電(dian)(dian)(dian)(dian)(dian)(dian)場的(de)(de)含(han)塵(chen)(chen)(chen)氣(qi)(qi)體(ti)由于(yu)電(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)通入高壓直流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian),則在電(dian)(dian)(dian)(dian)(dian)(dian)暈極(ji)附近產生電(dian)(dian)(dian)(dian)(dian)(dian)暈現象,使氣(qi)(qi)體(ti)電(dian)(dian)(dian)(dian)(dian)(dian)離,電(dian)(dian)(dian)(dian)(dian)(dian)離后的(de)(de)氣(qi)(qi)體(ti)中存在大(da)量的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)子和離子,使粉塵(chen)(chen)(chen)帶(dai)有電(dian)(dian)(dian)(dian)(dian)(dian)子同(tong)時(shi)使其(qi)吸附在陰(yin)極(ji)板(ban)上(shang)。后通過設(she)備陰(yin)陽(yang)極(ji)振(zhen)打系統的(de)(de)振(zhen)打,使沉積(ji)在陰(yin)陽(yang)電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)上(shang)的(de)(de)粉塵(chen)(chen)(chen)振(zhen)落,進入集(ji)灰(hui)(hui)斗通過排(pai)灰(hui)(hui)裝置排(pai)出(chu)。
要想讓含塵(chen)氣(qi)體更(geng)為(wei)均(jun)勻(yun)地(di)進入(ru)到電場當中(zhong),所以(yi)在臥式電除塵(chen)器(qi)當中(zhong),在進入(ru)設備時內按需設置(zhi)一至三道氣(qi)流(liu)分布(bu)板(ban)(ban)和導流(liu)板(ban)(ban),這樣可以(yi)讓氣(qi)流(liu)分布(bu)更(geng)為(wei)均(jun)勻(yun),從而實現(xian)良好的效果,并且還(huan)不容易(yi)出現(xian)堵孔(kong)等問題。
臥式電(dian)除塵器優勢
(1)初(chu)期除塵(chen)效率能達(da)到99%,能捕集1um以下的(de)細微粉塵(chen),但(dan)從經濟方面考(kao)慮,一般控制一個合理的(de)除塵(chen)效率。
(2)處理煙氣量大,可(ke)用于(yu)高溫(wen)(可(ke)高達(da)500℃)、高壓和高濕(shi)(相(xiang)對濕(shi)度(du)可(ke)達(da)100%)的場合,能(neng)連續運轉,并能(neng)實現自動化。
(3)具有(you)低阻的(de)特點,電除塵器壓力損失僅200~500Pa。
(4)靜電(dian)除(chu)(chu)塵器運(yun)行費(fei)用低 , 靜電(dian)除(chu)(chu)塵器運(yun)行穩定(ding), 故障(zhang)率極(ji)低;
應(ying)用范圍
對(dui)酸(suan)霧、有毒重金(jin)屬以(yi)及(ji)PM10,尤其(qi)是PM2.5的(de)(de)(de)微細粉(fen)塵有良好的(de)(de)(de)聯合脫除效果,對(dui)于減(jian)少(shao)燃煤鍋(guo)爐(lu)、鋼鐵(tie)燒(shao)結機、玻(bo)璃(li)爐(lu)窯、煤炭(tan)化等多行業的(de)(de)(de)粉(fen)塵排放量,減(jian)少(shao)大(da)氣(qi)污染,減(jian)低霧霾(mai)天氣(qi)機率,具有良好的(de)(de)(de)效果。適用(yong)于電廠燃煤鍋(guo)爐(lu)、有色治金(jin)爐(lu)窯、玻(bo)璃(li)生產(chan)(chan)(chan)爐(lu)窯、水泥生產(chan)(chan)(chan)爐(lu)窯、化工生產(chan)(chan)(chan)線、紡織生產(chan)(chan)(chan)線、及(ji)其(qi)它(ta)行業等經脫硫、脫硝(xiao)后含PM2.5、氣(qi)溶膠(jiao)、酸(suan)霧霧滴煙氣(qi)的(de)(de)(de)處理。
