臥式電(dian)除塵(chen)器是靜(jing)電(dian)除塵(chen)器的一種,是按氣流(liu)方向來定(ding)義的。
工作(zuo)(zuo)原(yuan)理:當含(han)塵(chen)氣(qi)體(ti)進(jin)入(ru)除塵(chen)器入(ru)口時,含(han)塵(chen)氣(qi)體(ti)在(zai)(zai)氣(qi)流分布板(ban)以及折(zhe)流板(ban)的(de)均(jun)(jun)化(hua)下(xia),氣(qi)流均(jun)(jun)勻向電(dian)(dian)(dian)(dian)(dian)場邁進(jin),在(zai)(zai)入(ru)口橫斷面擴大的(de)作(zuo)(zuo)用下(xia),氣(qi)流速度迅速降低(di),其(qi)中(zhong)一些較重的(de)塵(chen)粒便失去(qu)速度而(er)沉降下(xia)來。進(jin)入(ru)電(dian)(dian)(dian)(dian)(dian)場的(de)含(han)塵(chen)氣(qi)體(ti)由于電(dian)(dian)(dian)(dian)(dian)暈(yun)極通(tong)(tong)入(ru)高壓直流電(dian)(dian)(dian)(dian)(dian),則在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)暈(yun)極附近產(chan)生(sheng)電(dian)(dian)(dian)(dian)(dian)暈(yun)現象,使(shi)(shi)氣(qi)體(ti)電(dian)(dian)(dian)(dian)(dian)離,電(dian)(dian)(dian)(dian)(dian)離后的(de)氣(qi)體(ti)中(zhong)存在(zai)(zai)大量(liang)的(de)電(dian)(dian)(dian)(dian)(dian)子和離子,使(shi)(shi)粉塵(chen)帶有電(dian)(dian)(dian)(dian)(dian)子同時使(shi)(shi)其(qi)吸附在(zai)(zai)陰(yin)極板(ban)上。后通(tong)(tong)過設備陰(yin)陽極振打系統的(de)振打,使(shi)(shi)沉積在(zai)(zai)陰(yin)陽電(dian)(dian)(dian)(dian)(dian)極上的(de)粉塵(chen)振落(luo),進(jin)入(ru)集灰(hui)斗(dou)通(tong)(tong)過排灰(hui)裝(zhuang)置(zhi)排出。
要想(xiang)讓含塵氣體更為(wei)均勻地進入到電場當(dang)中(zhong),所(suo)以(yi)在臥式電除塵器當(dang)中(zhong),在進入設(she)備時內按(an)需設(she)置一至三(san)道氣流分布(bu)板(ban)和導流板(ban),這樣可以(yi)讓氣流分布(bu)更為(wei)均勻,從而實現良好的效果,并且還不容易(yi)出現堵孔等(deng)問題。
臥式電除(chu)塵(chen)器優勢
(1)初(chu)期除(chu)塵(chen)效率能達到99%,能捕(bu)集(ji)1um以下的(de)細微粉塵(chen),但(dan)從經濟方面考慮(lv),一(yi)般控制(zhi)一(yi)個合理的(de)除(chu)塵(chen)效率。
(2)處理煙氣量(liang)大,可用(yong)于(yu)高溫(wen)(可高達500℃)、高壓(ya)和(he)高濕(相對濕度可達100%)的場合,能連續(xu)運轉,并能實現自動化。
(3)具有低(di)阻的特點(dian),電除(chu)塵(chen)器壓(ya)力損失僅200~500Pa。
(4)靜(jing)電除塵器(qi)運行(xing)費用低 , 靜(jing)電除塵器(qi)運行(xing)穩定, 故障率極(ji)低;
