志新炭素廠電捕焦油(you)器(qi)分為(wei)上(shang)、中(zhong)、下3段,上(shang)、中(zhong)部(bu)為(wei)高壓(ya)靜電場,下部(bu)為(wei)集灰室。焙燒爐煙氣(qi)由下端(duan)側面進(jin)入,凈(jing)化后的潔凈(jing)氣(qi)體由上(shang)端(duan)頂部(bu)排出(chu)。

在(zai)除(chu)塵器內部(bu),每個正(zheng)方(fang)體的(de)(de)(de)(de)陽極板與其正(zheng)中的(de)(de)(de)(de)1根電(dian)(dian)(dian)暈線構(gou)成一(yi)(yi)(yi)(yi)個電(dian)(dian)(dian)場(chang)。炭素(su)廠18室(shi)(shi)-34室(shi)(shi)焙燒(shao)一(yi)(yi)(yi)(yi)般(ban)(ban)采(cai)用(yong)(yong)(yong)2-3個電(dian)(dian)(dian)場(chang),面積一(yi)(yi)(yi)(yi)般(ban)(ban)采(cai)用(yong)(yong)(yong)30-60m2。一(yi)(yi)(yi)(yi)次電(dian)(dian)(dian)流(liu)一(yi)(yi)(yi)(yi)般(ban)(ban)為50-150A,二(er)次電(dian)(dian)(dian)壓(ya)一(yi)(yi)(yi)(yi)般(ban)(ban)為45-80KV。電(dian)(dian)(dian)捕(bu)(bu)法對(dui)瀝青煙氣(qi)中焦油的(de)(de)(de)(de)處(chu)理效率(lv)主要取決于電(dian)(dian)(dian)捕(bu)(bu)焦油器除(chu)塵面積大小和二(er)次電(dian)(dian)(dian)壓(ya)(高(gao)(gao)壓(ya))的(de)(de)(de)(de)大小。除(chu)塵面積的(de)(de)(de)(de)增加可通過增加電(dian)(dian)(dian)場(chang)個數來實現(xian)。二(er)次電(dian)(dian)(dian)壓(ya)高(gao)(gao)低的(de)(de)(de)(de)調整可以通過對(dui)一(yi)(yi)(yi)(yi)次電(dian)(dian)(dian)流(liu)的(de)(de)(de)(de)調整來實現(xian)。當(dang)煙氣(qi)量小且運(yun)行爐室(shi)(shi)少時(shi),可采(cai)用(yong)(yong)(yong)較低電(dian)(dian)(dian)流(liu),當(dang)煙氣(qi)濃(nong)度大且運(yun)行爐室(shi)(shi)多時(shi),可采(cai)用(yong)(yong)(yong)較高(gao)(gao)電(dian)(dian)(dian)流(liu)。

電捕焦油器設計原則

由(you)于瀝青煙(yan)性質，成分復(fu)雜，治(zhi)理(li)難度較(jiao)大，為治(zhi)理(li)效果和系統的(de)長期(qi)穩定運(yun)行(xing)，通過反復(fu)論證(zheng)、反復(fu)研究、優化設(she)計，在總(zong)體設(she)計上堅持以下原則(ze)：

新的(de)(de)凈(jing)化工藝流程順暢(chang)、投資省、能(neng)耗(hao)低(di)、操作簡便，不影響焙燒(shao)爐的(de)(de)運行；

在凈化(hua)效率的同(tong)時，充分(fen)考慮(lv)系(xi)統(tong)的長期穩定運行(xing)，注重防范措施，避免由(you)于瀝青粉(fen)塵(chen)著火給設備造成損失；

充分考慮煙氣中(zhong)粉塵(chen)濃度(du)大于瀝青煙濃度(du)對(dui)(dui)系統(tong)的(de)影(ying)響（排灰、電暈封閉等問題），對(dui)(dui)電捕器進行(xing)優化設(she)計，

充分利用現有場地(di)情況，優化(hua)工(gong)藝配置，設備配置緊湊合理。

蜂窩式電捕(bu)焦油器原理：

 從炭素焙燒爐排(pai)出的(de)高(gao)溫煙(yan)(yan)(yan)氣(qi)(qi)(qi),在風機(ji)負壓作(zuo)用(yong)(yong)下,由集(ji)煙(yan)(yan)(yan)道匯集(ji)到主煙(yan)(yan)(yan)道,經(jing)過(guo)風量調節(jie)閥,進(jin)(jin)入(ru)水(shui)洗塔(ta),水(shui)流從上至(zhi)下通(tong)過(guo),使高(gao)溫煙(yan)(yan)(yan)氣(qi)(qi)(qi)冷(leng)卻。其作(zuo)用(yong)(yong)是一(yi)方面可去除(chu)煙(yan)(yan)(yan)氣(qi)(qi)(qi)中(zhong)顆(ke)粒(li)較大(da)的(de)粉塵和二(er)氧化硫,達到預(yu)處理作(zuo)用(yong)(yong),另一(yi)方面可降(jiang)低煙(yan)(yan)(yan)氣(qi)(qi)(qi)溫度,從而降(jiang)低了煙(yan)(yan)(yan)氣(qi)(qi)(qi)比(bi)電(dian)(dian)(dian)阻(zu),便于顆(ke)粒(li)物和瀝(li)青煙(yan)(yan)(yan)在電(dian)(dian)(dian)場中(zhong)荷(he)電(dian)(dian)(dian)。預(yu)處理后的(de)煙(yan)(yan)(yan)氣(qi)(qi)(qi)進(jin)(jin)入(ru)電(dian)(dian)(dian)捕(bu)焦(jiao)油(you)器(qi)(qi),煙(yan)(yan)(yan)氣(qi)(qi)(qi)顆(ke)粒(li)在電(dian)(dian)(dian)捕(bu)焦(jiao)油(you)器(qi)(qi)內荷(he)電(dian)(dian)(dian)、收集(ji),凈化后的(de)煙(yan)(yan)(yan)氣(qi)(qi)(qi)通(tong)過(guo)引風機(ji)送入(ru)50m高(gao)、1.4m內徑(jing)的(de)煙(yan)(yan)(yan)囪(cong)高(gao)空排(pai)放。電(dian)(dian)(dian)捕(bu)焦(jiao)油(you)除(chu)塵器(qi)(qi)捕(bu)集(ji)下來的(de)焦(jiao)油(you)物質和煙(yan)(yan)(yan)塵顆(ke)粒(li)定期排(pai)入(ru)除(chu)塵器(qi)(qi)下部的(de)貯油(you)罐。
