一、石灰廠燒結煙塵(chen)簡(jian)述(shu)：

石(shi)(shi)灰(hui)(hui)(hui)廠在生(sheng)產(chan)的時候，有(you)一道燒結工序(xu)。用(yong)生(sheng)石(shi)(shi)灰(hui)(hui)(hui)替代石(shi)(shi)灰(hui)(hui)(hui)石(shi)(shi)作(zuo)為熔劑，可以強(qiang)化(hua)燒結生(sheng)產(chan)，提(ti)高(gao)燒結礦(kuang)產(chan)量(liang)和質量(liang)，降低固體燃料消(xiao)耗，但是(shi)在生(sheng)石(shi)(shi)灰(hui)(hui)(hui)消(xiao)化(hua)過程中，產(chan)生(sheng)大量(liang)蒸汽和粉塵(chen)，現場環境差(cha)。生(sheng)石(shi)(shi)灰(hui)(hui)(hui)粉塵(chen)斷(duan)裂(lie)強(qiang)度大于(yu)600Pa，屬于(yu)強(qiang)親水(shui)性和強(qiang)粘結性粉塵(chen)，易結塊或(huo)黏附于(yu)除塵(chen)器(qi)(qi)及(ji)管道內壁(bi)。采用(yong)傳(chuan)統的布(bu)袋(dai)除塵(chen)器(qi)(qi)或(huo)干式(shi)電(dian)除塵(chen)器(qi)(qi)，由于(yu)粉塵(chen)中含有(you)CaO成分(fen)以及(ji)水(shui)蒸氣(qi)，會造(zao)成布(bu)袋(dai)除塵(chen)器(qi)(qi)糊堵，干式(shi)電(dian)除塵(chen)器(qi)(qi)易掛泥導致腐蝕嚴重(zhong)，除塵(chen)效果較差(cha)。

二、石(shi)灰廠(chang)燒結煙塵除塵方案：

結(jie)合石(shi)灰(hui)廠燒結(jie)工況和多年粉(fen)塵(chen)(chen)處理經(jing)(jing)驗，除塵(chen)(chen)設備使用(yong)氣(qi)動旋流(liu)(liu)塔+濕(shi)式(shi)靜電(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)器。濕(shi)式(shi)靜電(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)器的(de)工作原(yuan)理是：金屬放電(dian)(dian)(dian)(dian)(dian)線在直流(liu)(liu)高電(dian)(dian)(dian)(dian)(dian)壓的(de)作用(yong)下(xia)，將(jiang)其周(zhou)圍(wei)氣(qi)體(ti)電(dian)(dian)(dian)(dian)(dian)離，使粉(fen)塵(chen)(chen)或霧滴粒子(zi)表面荷電(dian)(dian)(dian)(dian)(dian)，荷電(dian)(dian)(dian)(dian)(dian)粒子(zi)在電(dian)(dian)(dian)(dian)(dian)場力的(de)作用(yong)下(xia)向收(shou)塵(chen)(chen)極運動，并沉(chen)積在收(shou)塵(chen)(chen)極上(shang)(shang)(shang)，水流(liu)(liu)從集塵(chen)(chen)板(ban)頂(ding)端(duan)流(liu)(liu)下(xia)，在集塵(chen)(chen)板(ban)上(shang)(shang)(shang)形成一層均勻(yun)穩定的(de)水膜，將(jiang)板(ban)上(shang)(shang)(shang)的(de)顆粒帶(dai)走。因此，濕(shi)式(shi)電(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)器與(yu)干(gan)式(shi)靜電(dian)(dian)(dian)(dian)(dian)除塵(chen)(chen)原(yuan)理相同，都要經(jing)(jing)歷(li)荷電(dian)(dian)(dian)(dian)(dian)、收(shou)集和清(qing)(qing)灰(hui)三(san)個階段(duan)。然(ran)而，與(yu)干(gan)式(shi)靜電(dian)(dian)(dian)(dian)(dian)清(qing)(qing)洗(xi)不同的(de)是，濕(shi)式(shi)靜電(dian)(dian)(dian)(dian)(dian)裝置(zhi)是采用(yong)液體(ti)沖(chong)刷集塵(chen)(chen)表面來進(jin)行清(qing)(qing)灰(hui)。

三、濕式靜電除(chu)塵(chen)器(qi)

環(huan)保濕(shi)電除塵(chen)(chen)(chen)器(qi)的(de)原(yuan)理(li)和干(gan)式(shi)吸塵(chen)(chen)(chen)器(qi)有著異曲(qu)同工之處，都是利(li)用高壓(ya)吸收灰塵(chen)(chen)(chen)，但是干(gan)式(shi)電除塵(chen)(chen)(chen)器(qi)主(zhu)要(yao)(yao)(yao)處理(li)含(han)水分量(liang)較低(di)的(de)有害氣(qi)體(ti)，濕(shi)式(shi)電除塵(chen)(chen)(chen)器(qi)和與干(gan)式(shi)電除塵(chen)(chen)(chen)器(qi)的(de)收塵(chen)(chen)(chen)原(yuan)理(li)相同，都是靠高壓(ya)電暈(yun)放電使(shi)得粉塵(chen)(chen)(chen)荷(he)電，荷(he)電后(hou)的(de)粉塵(chen)(chen)(chen)在電場力的(de)作(zuo)用下到(dao)達(da)集塵(chen)(chen)(chen)板(ban)管(guan)。干(gan)式(shi)電除塵(chen)(chen)(chen)器(qi)主(zhu)要(yao)(yao)(yao)處理(li)含(han)水很低(di)的(de)干(gan)氣(qi)體(ti)，濕(shi)式(shi)電除塵(chen)(chen)(chen)器(qi)則主(zhu)要(yao)(yao)(yao)進行含(han)水量(liang)較高的(de)有害氣(qi)體(ti)。

四、石灰(hui)廠燒結煙(yan)塵處理設備優勢：

1、細顆粒物凈化效率可達(da)95%以上，

2、酸霧(wu)、油煙(yan)氣體、水蒸氣移除凈化效率可達92%以上

3、設(she)備投(tou)資小，運(yun)行成(cheng)本低

4、自動安全保護、維護方便、使用壽命長、凈化效率高。
