目(mu)前焦化廠地面站(zhan)除塵器應(ying)用的三大技術：

1.攔焦(jiao)采用干管皮(pi)帶小車，爐(lu)頂采用M管煤氣回收(shou)技術。

2.攔焦采(cai)用(yong)干管皮帶小(xiao)車，爐頂(ding)采(cai)用(yong)導(dao)煙技術(shu)。

3.采(cai)用(yong)預噴布袋除塵，爐(lu)頂采(cai)用(yong)雙(shuang)對接導(dao)煙技術。

焦爐布袋除塵器工藝原理：

焦爐(lu)(lu)除(chu)塵(chen)(chen)地面站系統(tong)用(yong)于(yu)導(dao)(dao)通(tong)除(chu)塵(chen)(chen)器(qi)與攔(lan)焦車集塵(chen)(chen)罩(zhao),使(shi)焦側(ce)煙(yan)塵(chen)(chen)通(tong)過此干(gan)管(guan)進(jin)入(ru)除(chu)塵(chen)(chen)地面站進(jin)行處理,是移動塵(chen)(chen)源與固(gu)(gu)(gu)定設備之(zhi)間的(de)(de)連接(jie)(jie)通(tong)道.出焦集塵(chen)(chen)干(gan)管(guan)由固(gu)(gu)(gu)定接(jie)(jie)口翻板(ban)(ban)(ban)閥、伸縮器(qi)、平(ping)衡翻板(ban)(ban)(ban)閥、干(gan)管(guan)端部消(xiao)音器(qi)組成(cheng).固(gu)(gu)(gu)定翻板(ban)(ban)(ban)閥由閥板(ban)(ban)(ban)、支臂、管(guan)體等部分(fen)組成(cheng).焦爐(lu)(lu)出焦時(shi),攔(lan)焦車的(de)(de)液壓推(tui)桿(gan)將該翻板(ban)(ban)(ban)閥的(de)(de)翻板(ban)(ban)(ban)推(tui)開,閥門控(kong)制桿(gan)旋轉75度使(shi)閥門打開,攔(lan)焦車導(dao)(dao)管(guan)的(de)(de)可伸縮接(jie)(jie)口與該翻板(ban)(ban)(ban)閥端面對接(jie)(jie),使(shi)含(han)塵(chen)(chen)煙(yan)氣由攔(lan)焦車集塵(chen)(chen)罩(zhao)進(jin)入(ru)由固(gu)(gu)(gu)定翻板(ban)(ban)(ban)閥組成(cheng)的(de)(de)集塵(chen)(chen)干(gan)管(guan);推(tui)焦完(wan)成(cheng)后,攔(lan)焦車上的(de)(de)液壓推(tui)桿(gan)及可伸縮接(jie)(jie)口退(tui)回,該翻板(ban)(ban)(ban)閥關閉(bi),完(wan)成(cheng)一(yi)爐(lu)(lu)除(chu)塵(chen)(chen)計劃.固(gu)(gu)(gu)定翻板(ban)(ban)(ban)閥處于(yu)高(gao)溫狀(zhuang)態又處于(yu)經(jing)常(chang)開、閉(bi)狀(zhuang)態,受熱不(bu)(bu)變(bian)型,采用(yong)U型骨架周邊均布,使(shi)閥板(ban)(ban)(ban)長期使(shi)用(yong)不(bu)(bu)變(bian)型,在密封(feng)處加金屬(shu)絲(si)石棉密封(feng)墊,閥門密封(feng)效果;每組翻板(ban)(ban)(ban)閥之(zhi)間、翻板(ban)(ban)(ban)閥與直(zhi)管(guan)段之(zhi)間以及平(ping)衡閥、伸縮節(jie)和(he)端部消(xiao)聲器(qi)法蘭之(zhi)間使(shi)用(yong)金屬(shu)纏繞墊,靜(jing)密封(feng)漏(lou)氣率低于(yu)0.5%.

??由(you)于焦爐的工(gong)藝特(te)點即煉焦用煤揮發份,裝煤時會產(chan)生大(da)(da)量的煙(yan)塵(chen),針對裝煤煙(yan)塵(chen)煙(yan)氣含濕(shi)量大(da)(da)，露(lu)點溫度(du)比較高,且煙(yan)塵(chen)呈(cheng)絮狀,漂浮性等特(te)點,焦化廠(chang)治理大(da)(da)氣環(huan)境污(wu)染采用阻火布袋除塵(chen)地面站(zhan)系(xi)統,除塵(chen)效果(guo)理想。
