臥式(shi)電(dian)除(chu)塵器是靜電(dian)除(chu)塵器的一種(zhong),是按氣(qi)流(liu)方向來定義的。
工作原理:當含塵(chen)(chen)氣(qi)體(ti)(ti)進入(ru)除塵(chen)(chen)器入(ru)口時(shi),含塵(chen)(chen)氣(qi)體(ti)(ti)在(zai)(zai)氣(qi)流分布板(ban)以及折(zhe)流板(ban)的(de)(de)均(jun)化(hua)下(xia),氣(qi)流均(jun)勻(yun)向電(dian)(dian)(dian)(dian)(dian)場(chang)邁進,在(zai)(zai)入(ru)口橫斷面(mian)擴(kuo)大的(de)(de)作用下(xia),氣(qi)流速度迅速降低,其中(zhong)(zhong)一些較(jiao)重(zhong)的(de)(de)塵(chen)(chen)粒便失去速度而沉(chen)降下(xia)來。進入(ru)電(dian)(dian)(dian)(dian)(dian)場(chang)的(de)(de)含塵(chen)(chen)氣(qi)體(ti)(ti)由于電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)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(ji)(ji)附近產生電(dian)(dian)(dian)(dian)(dian)暈(yun)現象(xiang),使(shi)氣(qi)體(ti)(ti)電(dian)(dian)(dian)(dian)(dian)離,電(dian)(dian)(dian)(dian)(dian)離后的(de)(de)氣(qi)體(ti)(ti)中(zhong)(zhong)存在(zai)(zai)大量的(de)(de)電(dian)(dian)(dian)(dian)(dian)子(zi)和(he)離子(zi),使(shi)粉塵(chen)(chen)帶(dai)有電(dian)(dian)(dian)(dian)(dian)子(zi)同時(shi)使(shi)其吸附在(zai)(zai)陰極(ji)(ji)板(ban)上。后通(tong)(tong)過設備(bei)陰陽極(ji)(ji)振(zhen)(zhen)打系統的(de)(de)振(zhen)(zhen)打,使(shi)沉(chen)積在(zai)(zai)陰陽電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上的(de)(de)粉塵(chen)(chen)振(zhen)(zhen)落,進入(ru)集灰斗通(tong)(tong)過排灰裝置(zhi)排出。
要想讓含塵氣體更(geng)為(wei)均(jun)勻(yun)地進入到(dao)電(dian)(dian)場當中,所以在臥(wo)式電(dian)(dian)除塵器當中,在進入設備時(shi)內按需設置一至三道氣流(liu)分布(bu)板(ban)(ban)和導流(liu)板(ban)(ban),這樣可以讓氣流(liu)分布(bu)更(geng)為(wei)均(jun)勻(yun),從而實現良(liang)好的效(xiao)果,并且還不容易出(chu)現堵孔等問(wen)題(ti)。
臥式電(dian)除塵器優勢
(1)初期除塵(chen)(chen)(chen)效率能達到99%,能捕集1um以(yi)下(xia)的(de)細微(wei)粉塵(chen)(chen)(chen),但(dan)從經(jing)濟方面考慮,一般控制一個合理的(de)除塵(chen)(chen)(chen)效率。
(2)處(chu)理(li)煙氣(qi)量(liang)大(da),可用于(yu)高(gao)(gao)溫(可高(gao)(gao)達500℃)、高(gao)(gao)壓和(he)高(gao)(gao)濕(相對濕度可達100%)的場合,能連續運轉,并能實現自動化(hua)。
(3)具有低(di)阻的特點(dian),電(dian)除塵器(qi)壓力損失僅(jin)200~500Pa。
(4)靜電除塵(chen)器運行費用低 , 靜電除塵(chen)器運行穩定(ding), 故障率極低;
應用范圍(wei)
