臥式電除塵(chen)器是靜電除塵(chen)器的(de)一(yi)種,是按(an)氣流方向來定義(yi)的(de)。
工(gong)作原理:當含塵(chen)(chen)氣(qi)(qi)(qi)(qi)(qi)體進(jin)入(ru)除(chu)塵(chen)(chen)器(qi)入(ru)口(kou)時(shi),含塵(chen)(chen)氣(qi)(qi)(qi)(qi)(qi)體在氣(qi)(qi)(qi)(qi)(qi)流(liu)(liu)分布板(ban)(ban)以及折流(liu)(liu)板(ban)(ban)的(de)(de)(de)(de)均化下,氣(qi)(qi)(qi)(qi)(qi)流(liu)(liu)均勻向電(dian)(dian)(dian)(dian)場邁進(jin),在入(ru)口(kou)橫(heng)斷(duan)面擴大的(de)(de)(de)(de)作用下,氣(qi)(qi)(qi)(qi)(qi)流(liu)(liu)速(su)度(du)迅速(su)降低,其中一些較重的(de)(de)(de)(de)塵(chen)(chen)粒便失去速(su)度(du)而沉(chen)降下來(lai)。進(jin)入(ru)電(dian)(dian)(dian)(dian)場的(de)(de)(de)(de)含塵(chen)(chen)氣(qi)(qi)(qi)(qi)(qi)體由(you)于電(dian)(dian)(dian)(dian)暈極(ji)通(tong)(tong)入(ru)高(gao)壓(ya)直(zhi)流(liu)(liu)電(dian)(dian)(dian)(dian),則在電(dian)(dian)(dian)(dian)暈極(ji)附近產生電(dian)(dian)(dian)(dian)暈現象(xiang),使(shi)氣(qi)(qi)(qi)(qi)(qi)體電(dian)(dian)(dian)(dian)離(li),電(dian)(dian)(dian)(dian)離(li)后的(de)(de)(de)(de)氣(qi)(qi)(qi)(qi)(qi)體中存在大量的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)子(zi)和(he)離(li)子(zi),使(shi)粉塵(chen)(chen)帶(dai)有電(dian)(dian)(dian)(dian)子(zi)同時(shi)使(shi)其吸附在陰極(ji)板(ban)(ban)上(shang)(shang)。后通(tong)(tong)過(guo)設備陰陽極(ji)振(zhen)打(da)系(xi)統的(de)(de)(de)(de)振(zhen)打(da),使(shi)沉(chen)積(ji)在陰陽電(dian)(dian)(dian)(dian)極(ji)上(shang)(shang)的(de)(de)(de)(de)粉塵(chen)(chen)振(zhen)落,進(jin)入(ru)集灰(hui)斗通(tong)(tong)過(guo)排灰(hui)裝置排出。
要(yao)想讓含塵氣(qi)(qi)體更(geng)(geng)為均勻地進(jin)入(ru)到電場當中,所以(yi)在臥式電除塵器當中,在進(jin)入(ru)設備時內按需設置一至三道氣(qi)(qi)流分布板和(he)導(dao)流板,這樣可以(yi)讓氣(qi)(qi)流分布更(geng)(geng)為均勻,從而(er)實現良好的效果,并且(qie)還不容易出現堵孔(kong)等問(wen)題。
臥(wo)式電除(chu)塵器優勢
(1)初期除塵效(xiao)(xiao)率(lv)能達到99%,能捕集1um以(yi)下(xia)的細微粉塵,但從經濟方面考慮,一般(ban)控制一個合理(li)的除塵效(xiao)(xiao)率(lv)。
(2)處理煙氣量(liang)大,可(ke)(ke)用于(yu)高(gao)溫(可(ke)(ke)高(gao)達500℃)、高(gao)壓(ya)和高(gao)濕(shi)(shi)(相對濕(shi)(shi)度(du)可(ke)(ke)達100%)的場(chang)合(he),能(neng)連續(xu)運轉(zhuan),并能(neng)實現自動化(hua)。
(3)具有低(di)阻的特點,電除塵器(qi)壓力損失僅200~500Pa。
(4)靜(jing)電(dian)除塵(chen)器運行費用(yong)低(di) , 靜(jing)電(dian)除塵(chen)器運行穩定, 故障率極低(di);
應用范圍
