臥式電除(chu)塵器是靜電除(chu)塵器的一(yi)種,是按氣流方向來定義的。
工作(zuo)原理:當含(han)(han)塵(chen)(chen)(chen)氣(qi)體(ti)(ti)(ti)進(jin)(jin)入(ru)(ru)(ru)除塵(chen)(chen)(chen)器入(ru)(ru)(ru)口時,含(han)(han)塵(chen)(chen)(chen)氣(qi)體(ti)(ti)(ti)在(zai)氣(qi)流(liu)分布板(ban)以及(ji)折流(liu)板(ban)的(de)均(jun)化下(xia),氣(qi)流(liu)均(jun)勻向電(dian)(dian)(dian)(dian)場邁進(jin)(jin),在(zai)入(ru)(ru)(ru)口橫斷面(mian)擴(kuo)大(da)的(de)作(zuo)用下(xia),氣(qi)流(liu)速(su)度(du)迅速(su)降低,其中一些較重的(de)塵(chen)(chen)(chen)粒便失去速(su)度(du)而(er)沉降下(xia)來(lai)。進(jin)(jin)入(ru)(ru)(ru)電(dian)(dian)(dian)(dian)場的(de)含(han)(han)塵(chen)(chen)(chen)氣(qi)體(ti)(ti)(ti)由于電(dian)(dian)(dian)(dian)暈(yun)極(ji)通(tong)入(ru)(ru)(ru)高壓(ya)直流(liu)電(dian)(dian)(dian)(dian),則在(zai)電(dian)(dian)(dian)(dian)暈(yun)極(ji)附近產生(sheng)電(dian)(dian)(dian)(dian)暈(yun)現象,使(shi)氣(qi)體(ti)(ti)(ti)電(dian)(dian)(dian)(dian)離,電(dian)(dian)(dian)(dian)離后的(de)氣(qi)體(ti)(ti)(ti)中存在(zai)大(da)量的(de)電(dian)(dian)(dian)(dian)子(zi)和離子(zi),使(shi)粉塵(chen)(chen)(chen)帶(dai)有(you)電(dian)(dian)(dian)(dian)子(zi)同時使(shi)其吸附在(zai)陰極(ji)板(ban)上。后通(tong)過設備陰陽極(ji)振(zhen)打系統的(de)振(zhen)打,使(shi)沉積在(zai)陰陽電(dian)(dian)(dian)(dian)極(ji)上的(de)粉塵(chen)(chen)(chen)振(zhen)落(luo),進(jin)(jin)入(ru)(ru)(ru)集灰斗通(tong)過排(pai)灰裝置排(pai)出。
要想讓(rang)含塵氣(qi)體(ti)更為均(jun)勻地進入到(dao)電(dian)場當(dang)(dang)中(zhong)(zhong),所以在臥式電(dian)除塵器當(dang)(dang)中(zhong)(zhong),在進入設備時內(nei)按(an)需設置(zhi)一至三道(dao)氣(qi)流(liu)分布板和導(dao)流(liu)板,這樣可以讓(rang)氣(qi)流(liu)分布更為均(jun)勻,從而實現(xian)良好的(de)效果,并(bing)且還(huan)不(bu)容(rong)易(yi)出現(xian)堵孔等問題。
臥(wo)式電除(chu)塵器優勢
(1)初期(qi)除(chu)(chu)塵效率(lv)能(neng)達到(dao)99%,能(neng)捕集1um以下的(de)細(xi)微粉塵,但從經濟方面考慮,一般控(kong)制(zhi)一個(ge)合理的(de)除(chu)(chu)塵效率(lv)。
(2)處理煙氣量大,可用于高(gao)(gao)溫(可高(gao)(gao)達(da)500℃)、高(gao)(gao)壓和高(gao)(gao)濕(shi)(相對(dui)濕(shi)度可達(da)100%)的場合,能連續運轉,并能實(shi)現(xian)自(zi)動(dong)化。
(3)具有低(di)阻的特點,電除塵器(qi)壓力損(sun)失僅(jin)200~500Pa。
(4)靜電除(chu)塵器運(yun)行(xing)費用低(di) , 靜電除(chu)塵器運(yun)行(xing)穩定(ding), 故障(zhang)率極低(di);
應用(yong)范圍
對(dui)酸霧、有毒重金(jin)屬以(yi)及PM10,尤其是PM2.5的(de)微細粉塵(chen)(chen)有良好的(de)聯(lian)合脫除效果,對(dui)于(yu)減(jian)少燃(ran)煤(mei)鍋(guo)爐、鋼鐵(tie)燒結機(ji)、玻璃(li)爐窯(yao)(yao)(yao)、煤(mei)炭化(hua)等(deng)多行業(ye)的(de)粉塵(chen)(chen)排放量(liang),減(jian)少大氣污(wu)染,減(jian)低霧霾天氣機(ji)率,具有良好的(de)效果。適用(yong)于(yu)電廠燃(ran)煤(mei)鍋(guo)爐、有色(se)治(zhi)金(jin)爐窯(yao)(yao)(yao)、玻璃(li)生產爐窯(yao)(yao)(yao)、水泥生產爐窯(yao)(yao)(yao)、化(hua)工生產線(xian)(xian)、紡織生產線(xian)(xian)、及其它行業(ye)等(deng)經(jing)脫硫、脫硝后含(han)PM2.5、氣溶膠、酸霧霧滴(di)煙氣的(de)處理。
