高爐煤氣布袋除塵器刮板是卸灰機嗎？高溫袋式除塵器的研究和應用可以提高袋式除塵器的除塵效果，減少設備故障。國內高爐煤氣布袋除塵器采用的布袋除塵器有兩種：反吹內濾袋除塵器和低壓長袋外濾袋脈沖布袋除塵器。自1989年以來，國(guo)產反吹袋(dai)(dai)式除(chu)(chu)塵(chen)器(qi)(qi)(qi)已用于高爐煤氣凈化。由于其除(chu)(chu)灰強度低(di)，過濾負荷小(xiao)，資金投入(ru)大，除(chu)(chu)塵(chen)箱多，除(chu)(chu)灰頻繁。隨(sui)著除(chu)(chu)塵(chen)技術的(de)發(fa)展，脈(mo)沖(chong)(chong)閥、電磁(ci)閥和脈(mo)沖(chong)(chong)隔膜的(de)故障率有所降低(di)。我國(guo)所有煉鐵企業(ye)均對原(yuan)有除(chu)(chu)塵(chen)器(qi)(qi)(qi)進行了技術改造，采用低(di)壓長袋(dai)(dai)外濾脈(mo)沖(chong)(chong)除(chu)(chu)塵(chen)器(qi)(qi)(qi)。確定了長袋(dai)(dai)外濾器(qi)(qi)(qi)脈(mo)沖(chong)(chong)除(chu)(chu)塵(chen)器(qi)(qi)(qi)。

高爐煤氣(qi)布(bu)袋除塵器輸送系統：

卸灰(hui)(hui)輸(shu)(shu)(shu)送(song)系統(tong)采用氮(dan)(dan)氣(qi)(qi)(qi)氣(qi)(qi)(qi)力(li)輸(shu)(shu)(shu)送(song)，由氣(qi)(qi)(qi)力(li)卸灰(hui)(hui)球(qiu)閥(fa)(fa)、氣(qi)(qi)(qi)動(dong)(dong)(dong)鐘形閥(fa)(fa)、氣(qi)(qi)(qi)動(dong)(dong)(dong)球(qiu)閥(fa)(fa)、輸(shu)(shu)(shu)灰(hui)(hui)管道、大(da)型灰(hui)(hui)倉等組成(cheng)。卸灰(hui)(hui)輸(shu)(shu)(shu)送(song)系統(tong)工藝流程如下：除塵器(qi)灰(hui)(hui)斗→DN300氣(qi)(qi)(qi)動(dong)(dong)(dong)卸灰(hui)(hui)球(qiu)閥(fa)(fa)→DN300氣(qi)(qi)(qi)動(dong)(dong)(dong)鐘型閥(fa)(fa)→DN100氣(qi)(qi)(qi)動(dong)(dong)(dong)球(qiu)閥(fa)(fa)→DN150輸(shu)(shu)(shu)灰(hui)(hui)管道→大(da)型灰(hui)(hui)庫(ku)。壓縮氮(dan)(dan)氣(qi)(qi)(qi)將(jiang)粉(fen)塵輸(shu)(shu)(shu)送(song)至大(da)型灰(hui)(hui)倉，通(tong)過灰(hui)(hui)倉頂部(bu)的袋(dai)式除塵器(qi)進行過濾，然后通(tong)過排氣(qi)(qi)(qi)管（氮(dan)(dan)氣(qi)(qi)(qi)）進行排氣(qi)(qi)(qi)。

袋式(shi)(shi)除塵器(qi)刮(gua)板和卸灰(hui)器(qi)不(bu)是同(tong)(tong)一產品(pin)，具有不(bu)同(tong)(tong)的(de)(de)功能。刮(gua)板一般指刮(gua)板輸(shu)送(song)(song)機(ji)。刮(gua)板輸(shu)送(song)(song)機(ji)的(de)(de)工作(zuo)(zuo)(zuo)原理是利用開(kai)式(shi)(shi)溜(liu)槽作(zuo)(zuo)(zuo)為煤、矸石或物料的(de)(de)承(cheng)載(zai)部(bu)分，刮(gua)板作(zuo)(zuo)(zuo)為牽(qian)引部(bu)件固定在鏈(lian)(lian)(lian)條(tiao)(tiao)上（形成刮(gua)板鏈(lian)(lian)(lian)條(tiao)(tiao)）。當頭部(bu)傳動(dong)部(bu)件啟(qi)動(dong)時，帶(dai)式(shi)(shi)輸(shu)送(song)(song)機(ji)頭部(bu)軸上的(de)(de)鏈(lian)(lian)(lian)輪旋轉，使刮(gua)板鏈(lian)(lian)(lian)條(tiao)(tiao)循環(huan)(huan)，并沿溜(liu)槽移動(dong)動(dong)物材(cai)料，直到動(dong)物材(cai)料在頭部(bu)卸載(zai)。刮(gua)板鏈(lian)(lian)(lian)條(tiao)(tiao)繞過鏈(lian)(lian)(lian)輪進行無級閉(bi)環(huan)(huan)操作(zuo)(zuo)(zuo)，完(wan)成物料輸(shu)送(song)(song)。刮(gua)板和卸灰(hui)器(qi)不(bu)是產品(pin)，但統稱為輸(shu)灰(hui)系(xi)統。
