焦化廠地(di)面站除塵器(qi)的組(zu)成(cheng)形(xing)式及原理：

焦爐地面除塵站由離心風機、主電機、變頻器、儀表系統、循環冷卻水系統、壓縮空氣系統及管網系統組成.在煉焦生產過程中,煙塵通過導管被吸入除塵干管,在重力除塵器內將大顆粒粉塵分離,直接流入灰斗.較小的粉塵均勻地進入布袋除塵器中(zhong)部的箱(xiang)體后(hou),吸附(fu)在濾(lv)(lv)袋(dai)的外表(biao)面(mian)上,含(han)塵(chen)氣體經濾(lv)(lv)袋(dai)過濾(lv)(lv)后(hou)進入(ru)凈氣室(shi),經排(pai)風管(guan)排(pai)入(ru)大(da)氣.當濾(lv)(lv)袋(dai)阻力(li)達到(dao)限定(ding)值1500Pa時,清灰裝置(zhi)按差壓(ya)程序(xu)打(da)開(kai)電控(kong)脈沖(chong)閥(fa)進行脈沖(chong)噴吹,此(ci)時壓(ya)縮空氣將濾(lv)(lv)袋(dai)表(biao)面(mian)附(fu)著(zhu)的粉(fen)塵(chen)抖落,經灰斗(dou)由排(pai)灰機(ji)構排(pai)出.該焦爐地(di)面(mian)站除塵(chen)系(xi)統采用PLC自動控(kong)制(zhi)技術,由除塵(chen)地(di)面(mian)站中(zhong)控(kong)制(zhi)室(shi)集(ji)中(zhong)監控(kong),同時還(huan)設置(zhi)了手動控(kong)制(zhi)開(kai)關,便(bian)于檢修(xiu).

焦爐(lu)地面站除塵器系統的使用效果:

    1.采用地面除塵(chen)站系統除塵(chen),降低了(le)煉(lian)焦爐(lu)生產(chan)區(qu)域的粉塵(chen)濃度,凈化了(le)工人生產(chan)操作環境,焦爐(lu)粉塵(chen)治理達到了(le)煉(lian)焦行業和環保(bao)排放標準.

    2.系(xi)統(tong)經過(guo)工藝改進后,提高了系(xi)統(tong)穩定性和性,沒有發(fa)生(sheng)任何事故.

    3.由(you)于操(cao)作(zuo)控制簡單,延(yan)(yan)長了系(xi)統(tong)設備(bei)的使(shi)(shi)用壽命(ming),特(te)別是除(chu)塵(chen)器布袋使(shi)(shi)用時(shi)間的延(yan)(yan)長.該系(xi)統(tong)使(shi)(shi)用18個月沒有更換(huan)過布袋,實現(xian)了經(jing)濟(ji)運行的目標.

    4.該焦(jiao)爐(lu)除塵地(di)面站系統(tong)(tong)變頻技術的成功應用,既節省了(le)用電費用,又了(le)系統(tong)(tong)干管吸力的穩定(ding),對整個焦(jiao)爐(lu)地(di)面站除塵系統(tong)(tong)穩定(ding)運行起到(dao)了(le)關鍵作用。
