焦爐設備

熄(xi)焦(jiao)(jiao)系統以干(gan)法熄(xi)焦(jiao)(jiao)為主(zhu)，當干(gan)熄(xi)焦(jiao)(jiao)裝(zhuang)置(zhi)年修(xiu)或出現(xian)故障(zhang)時(shi)，利用(yong)濕(shi)法熄(xi)焦(jiao)(jiao)系統熄(xi)焦(jiao)(jiao)。濕(shi)熄(xi)焦(jiao)(jiao)塔高約為53m，熄(xi)焦(jiao)(jiao)塔內設(she)有新型快(kuai)速熄(xi)焦(jiao)(jiao)裝(zhuang)置(zhi)、水霧捕集裝(zhuang)置(zhi)以及折流板式除塵裝(zhuang)置(zhi)。

一(yi)點定位(wei)式熄焦車到達熄焦塔固定位(wei)置后，熄焦系統開始對紅(hong)焦進(jin)行熄焦，時間控制在70～90s。熄焦后的焦炭(tan)水分(fen)可(ke)(ke)穩定在2％～3%,且焦炭(tan)的粒度加均勻(yun)，可(ke)(ke)大(da)大(da)改(gai)善高爐內的爐料透氣性。

當熄焦(jiao)系統(tong)開始(shi)工作時(shi)，水(shui)霧捕(bu)集系統(tong)也(ye)同(tong)時(shi)啟動，并(bing)(bing)在熄焦(jiao)塔(ta)內形成一層(ceng)水(shui)霧，熄焦(jiao)時(shi)產(chan)生(sheng)的(de)(de)(de)(de)(de)大量熄焦(jiao)逸散(san)物在熱(re)浮力的(de)(de)(de)(de)(de)作用下急劇上升(sheng)，在經(jing)過水(shui)霧捕(bu)集系統(tong)形成的(de)(de)(de)(de)(de)霧層(ceng)時(shi)得到冷(leng)卻(que)，蒸汽(qi)中的(de)(de)(de)(de)(de)粉塵(chen)顆粒(li)(li)一部(bu)(bu)分被洗滌(di)掉(diao)，其余(yu)大部(bu)(bu)分形成了以粉塵(chen)顆粒(li)(li)為(wei)(wei)內核的(de)(de)(de)(de)(de)冷(leng)凝液滴，隨蒸汽(qi)繼(ji)續上升(sheng)，進入熄焦(jiao)塔(ta)頂部(bu)(bu)的(de)(de)(de)(de)(de)折流板式除塵(chen)裝置(zhi)，在通(tong)過折流板捕(bu)塵(chen)格柵縫隙時(shi)，以粉塵(chen)顆粒(li)(li)為(wei)(wei)內核的(de)(de)(de)(de)(de)冷(leng)凝液滴被靜電(dian)吸收(shou)，并(bing)(bing)通(tong)過機械(xie)碰(peng)撞而沉(chen)淀在格柵上，后被凈化的(de)(de)(de)(de)(de)汽(qi)體從(cong)熄焦(jiao)塔(ta)出口排(pai)入大氣(qi)。除塵(chen)片上附著的(de)(de)(de)(de)(de)焦(jiao)粉顆粒(li)(li)定期用水(shui)噴淋(lin)洗滌(di)。
