臥式電除塵器是靜電除塵器的一種,是按氣流方(fang)向(xiang)來定義(yi)的。
工作原(yuan)理:當含塵(chen)氣(qi)(qi)體進(jin)入(ru)除塵(chen)器(qi)入(ru)口時,含塵(chen)氣(qi)(qi)體在氣(qi)(qi)流(liu)分(fen)布板以及折(zhe)流(liu)板的(de)(de)均化(hua)下(xia),氣(qi)(qi)流(liu)均勻向電(dian)(dian)(dian)(dian)(dian)場邁進(jin),在入(ru)口橫斷面擴大的(de)(de)作用下(xia),氣(qi)(qi)流(liu)速(su)度(du)迅速(su)降低,其(qi)中一些(xie)較重的(de)(de)塵(chen)粒便失去速(su)度(du)而沉降下(xia)來。進(jin)入(ru)電(dian)(dian)(dian)(dian)(dian)場的(de)(de)含塵(chen)氣(qi)(qi)體由于電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)通(tong)(tong)入(ru)高壓直流(liu)電(dian)(dian)(dian)(dian)(dian),則在電(dian)(dian)(dian)(dian)(dian)暈(yun)極(ji)(ji)附(fu)(fu)近(jin)產(chan)生電(dian)(dian)(dian)(dian)(dian)暈(yun)現(xian)象(xiang),使(shi)氣(qi)(qi)體電(dian)(dian)(dian)(dian)(dian)離,電(dian)(dian)(dian)(dian)(dian)離后(hou)的(de)(de)氣(qi)(qi)體中存在大量的(de)(de)電(dian)(dian)(dian)(dian)(dian)子(zi)和離子(zi),使(shi)粉塵(chen)帶有電(dian)(dian)(dian)(dian)(dian)子(zi)同時使(shi)其(qi)吸附(fu)(fu)在陰(yin)極(ji)(ji)板上(shang)。后(hou)通(tong)(tong)過設備陰(yin)陽極(ji)(ji)振打(da)系統的(de)(de)振打(da),使(shi)沉積(ji)在陰(yin)陽電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)上(shang)的(de)(de)粉塵(chen)振落,進(jin)入(ru)集灰斗(dou)通(tong)(tong)過排(pai)灰裝置排(pai)出。
要想讓含塵氣(qi)體更為均勻地(di)進入(ru)到電場當(dang)中(zhong),所以(yi)在(zai)臥式電除塵器當(dang)中(zhong),在(zai)進入(ru)設備時內按需(xu)設置(zhi)一(yi)至三道(dao)氣(qi)流(liu)(liu)分布(bu)板和導流(liu)(liu)板,這樣可以(yi)讓氣(qi)流(liu)(liu)分布(bu)更為均勻,從而實現良(liang)好(hao)的效果(guo),并且(qie)還不容易(yi)出現堵(du)孔等問題。
臥式電除(chu)塵器優(you)勢(shi)
(1)初期除(chu)(chu)塵效(xiao)率能達到99%,能捕集(ji)1um以下的(de)(de)細微粉塵,但從經(jing)濟(ji)方面(mian)考慮,一(yi)般控制一(yi)個合理的(de)(de)除(chu)(chu)塵效(xiao)率。
(2)處理煙氣量大,可(ke)(ke)用于高溫(可(ke)(ke)高達(da)500℃)、高壓和高濕(shi)(shi)(相(xiang)對濕(shi)(shi)度可(ke)(ke)達(da)100%)的場合,能連續(xu)運轉,并能實現自動化。
(3)具有(you)低阻的特點,電除塵器壓(ya)力損失僅200~500Pa。
(4)靜電除塵(chen)器運(yun)行費用(yong)低(di) , 靜電除塵(chen)器運(yun)行穩定, 故障率(lv)極低(di);
應用范圍
對酸(suan)霧、有毒重金(jin)屬(shu)以及PM10,尤其是PM2.5的微細粉塵有良(liang)好的聯合脫除效(xiao)果,對于(yu)減少(shao)燃煤鍋(guo)爐(lu)、鋼鐵(tie)燒結機(ji)、玻璃爐(lu)窯(yao)、煤炭化(hua)(hua)等(deng)多(duo)行業的粉塵排放(fang)量,減少(shao)大氣(qi)污(wu)染(ran),減低霧霾天氣(qi)機(ji)率,具有良(liang)好的效(xiao)果。適用于(yu)電廠燃煤鍋(guo)爐(lu)、有色治(zhi)金(jin)爐(lu)窯(yao)、玻璃生(sheng)產(chan)(chan)爐(lu)窯(yao)、水(shui)泥生(sheng)產(chan)(chan)爐(lu)窯(yao)、化(hua)(hua)工生(sheng)產(chan)(chan)線、紡織生(sheng)產(chan)(chan)線、及其它行業等(deng)經脫硫、脫硝后含PM2.5、氣(qi)溶膠(jiao)、酸(suan)霧霧滴煙氣(qi)的處理(li)。
