臥式電(dian)除塵(chen)(chen)器是(shi)靜電(dian)除塵(chen)(chen)器的一種,是(shi)按氣(qi)流方向(xiang)來定義(yi)的。
工作(zuo)原理:當含(han)塵氣(qi)(qi)體(ti)進入除塵器入口時,含(han)塵氣(qi)(qi)體(ti)在氣(qi)(qi)流分布板以及折流板的(de)均(jun)化下(xia),氣(qi)(qi)流均(jun)勻(yun)向(xiang)電(dian)(dian)(dian)(dian)(dian)場(chang)(chang)邁進,在入口橫斷面擴大的(de)作(zuo)用(yong)下(xia),氣(qi)(qi)流速度迅速降低(di),其中一些較重的(de)塵粒便失(shi)去速度而(er)沉降下(xia)來。進入電(dian)(dian)(dian)(dian)(dian)場(chang)(chang)的(de)含(han)塵氣(qi)(qi)體(ti)由于(yu)電(dian)(dian)(dian)(dian)(dian)暈極(ji)通入高壓直(zhi)流電(dian)(dian)(dian)(dian)(dian),則在電(dian)(dian)(dian)(dian)(dian)暈極(ji)附近產生電(dian)(dian)(dian)(dian)(dian)暈現(xian)象,使(shi)氣(qi)(qi)體(ti)電(dian)(dian)(dian)(dian)(dian)離,電(dian)(dian)(dian)(dian)(dian)離后(hou)的(de)氣(qi)(qi)體(ti)中存在大量的(de)電(dian)(dian)(dian)(dian)(dian)子和離子,使(shi)粉塵帶有電(dian)(dian)(dian)(dian)(dian)子同時使(shi)其吸附在陰極(ji)板上(shang)。后(hou)通過設備陰陽極(ji)振打(da)系統的(de)振打(da),使(shi)沉積在陰陽電(dian)(dian)(dian)(dian)(dian)極(ji)上(shang)的(de)粉塵振落(luo),進入集灰斗通過排(pai)灰裝置排(pai)出。
要想(xiang)讓含塵(chen)氣體更(geng)為(wei)均勻地進入到電(dian)場當(dang)中,所以(yi)在臥式電(dian)除塵(chen)器當(dang)中,在進入設(she)備時內按需設(she)置一至三(san)道氣流分(fen)布(bu)板(ban)和導流板(ban),這樣可以(yi)讓氣流分(fen)布(bu)更(geng)為(wei)均勻,從而(er)實現(xian)良(liang)好的效果(guo),并且還不容易出現(xian)堵孔等問(wen)題。
臥式電除塵(chen)器(qi)優勢
(1)初期除塵效率(lv)能(neng)達到99%,能(neng)捕(bu)集(ji)1um以下的細(xi)微粉塵,但從經(jing)濟(ji)方(fang)面考慮,一般控(kong)制(zhi)一個合理的除塵效率(lv)。
(2)處(chu)理煙氣量大,可用于高(gao)(gao)溫(可高(gao)(gao)達500℃)、高(gao)(gao)壓和(he)高(gao)(gao)濕(shi)(相對(dui)濕(shi)度(du)可達100%)的場合,能連續(xu)運(yun)轉(zhuan),并能實現自動化。
(3)具有低阻的(de)特點,電除塵器(qi)壓(ya)力損失僅200~500Pa。
(4)靜電除塵器運行費(fei)用低 , 靜電除塵器運行穩定, 故(gu)障率極低;
應用范圍
對酸霧(wu)、有(you)(you)(you)毒(du)重金(jin)屬以及(ji)PM10,尤其(qi)是PM2.5的微細粉(fen)塵有(you)(you)(you)良好的聯合脫除效(xiao)果(guo),對于(yu)減少(shao)燃(ran)煤鍋爐(lu)、鋼鐵燒結機(ji)、玻璃爐(lu)窯(yao)、煤炭(tan)化等多行業的粉(fen)塵排(pai)放量,減少(shao)大(da)氣污染,減低霧(wu)霾天氣機(ji)率,具有(you)(you)(you)良好的效(xiao)果(guo)。適用于(yu)電廠燃(ran)煤鍋爐(lu)、有(you)(you)(you)色治金(jin)爐(lu)窯(yao)、玻璃生(sheng)(sheng)產(chan)爐(lu)窯(yao)、水泥生(sheng)(sheng)產(chan)爐(lu)窯(yao)、化工生(sheng)(sheng)產(chan)線(xian)、紡織(zhi)生(sheng)(sheng)產(chan)線(xian)、及(ji)其(qi)它行業等經脫硫、脫硝后含(han)PM2.5、氣溶膠、酸霧(wu)霧(wu)滴煙氣的處理。
