生(sheng)物質鍋(guo)爐除(chu)塵(chen)器的運轉(zhuan)與保(bao)護(hu)近來十幾年,我國的除(chu)塵(chen)技術(shu)發展很(hen)快(kuai),清灰方(fang)法和濾料的改善(shan)使鍋(guo)爐除(chu)塵(chen)器的運用規模(mo)愈加廣泛。
生物(wu)質鍋爐(lu)除塵(chen)(chen)器除了(le)處(chu)理通常含塵(chen)(chen)氣(qi)體外,也能處(chu)理高(gao)溫、高(gao)濕、凝(ning)聚、磨(mo)琢及(ji)細煙塵(chen)(chen),有的(de)還(huan)作為出產過程中物(wu)料收(shou)回的(de)設(she)備。運(yun)用(yong)高(gao)壓風機(ji)或(huo)鼓(gu)風機(ji)作為反(fan)(fan)(fan)(fan)(fan)(fan)(fan)吹(chui)(chui)清(qing)(qing)灰(hui)動(dong)(dong)力(li)(li),通過移動(dong)(dong)噴嘴順次對(dui)濾(lv)袋噴吹(chui)(chui),構成劇(ju)烈反(fan)(fan)(fan)(fan)(fan)(fan)(fan)向(xiang)氣(qi)流,使(shi)濾(lv)袋急劇(ju)變形而清(qing)(qing)灰(hui),屬(shu)中等能量(liang)清(qing)(qing)灰(hui)類(lei)型。按噴嘴方法(fa)及(ji)其移動(dong)(dong)軌道可分為反(fan)(fan)(fan)(fan)(fan)(fan)(fan)轉反(fan)(fan)(fan)(fan)(fan)(fan)(fan)吹(chui)(chui)式(shi)(shi)(shi)、往(wang)(wang)復反(fan)(fan)(fan)(fan)(fan)(fan)(fan)吹(chui)(chui)式(shi)(shi)(shi)和(he)氣(qi)環(huan)滑(hua)動(dong)(dong)反(fan)(fan)(fan)(fan)(fan)(fan)(fan)吹(chui)(chui)式(shi)(shi)(shi)等三種。反(fan)(fan)(fan)(fan)(fan)(fan)(fan)轉反(fan)(fan)(fan)(fan)(fan)(fan)(fan)吹(chui)(chui)式(shi)(shi)(shi)和(he)往(wang)(wang)復反(fan)(fan)(fan)(fan)(fan)(fan)(fan)吹(chui)(chui)式(shi)(shi)(shi)清(qing)(qing)灰(hui)方法(fa)的(de)袋式(shi)(shi)(shi)鍋爐(lu)除塵(chen)(chen)器選(xuan)用(yong)帶構造的(de)外濾(lv)扁袋方法(fa),構造緊(jin)湊。脈(mo)(mo)沖(chong)噴吹(chui)(chui)式(shi)(shi)(shi)清(qing)(qing)灰(hui)方法(fa)以緊(jin)縮空(kong)氣(qi)為動(dong)(dong)力(li)(li),運(yun)用(yong)脈(mo)(mo)沖(chong)噴吹(chui)(chui)組織在剎(cha)那間開釋(shi)緊(jin)縮氣(qi)流,誘導數倍的(de)二次空(kong)氣(qi)高(gao)速(su)射入濾(lv)袋,使(shi)濾(lv)袋急劇(ju)脹大,依托沖(chong)擊振蕩和(he)反(fan)(fan)(fan)(fan)(fan)(fan)(fan)向(xiang)氣(qi)而清(qing)(qing)灰(hui),屬(shu)高(gao)動(dong)(dong)能清(qing)(qing)灰(hui)類(lei)型。
生物(wu)質鍋(guo)爐除(chu)塵器是(shi)專門用于處理燃(ran)(ran)煤鍋(guo)爐煙(yan)(yan)氣(qi)的(de)(de)除(chu)塵設備(bei),針對(dui)燃(ran)(ran)煤鍋(guo)爐煙(yan)(yan)氣(qi)的(de)(de)特(te)性:溫度高,煙(yan)(yan)氣(qi)含(han)濕量大(da),煙(yan)(yan)氣(qi)中(zhong)(zhong)含(han)有大(da)量硫(liu)成(cheng)分,具有很強的(de)(de)腐蝕性等特(te)點(dian),鍋(guo)爐布(bu)袋(dai)(dai)除(chu)塵器由(you)于運行平穩、低(di)阻(zu)、低(di)能耗、清灰(hui)效(xiao)果好、占地面積小的(de)(de)lcm型離線清灰(hui)長袋(dai)(dai)脈沖袋(dai)(dai)式除(chu)塵器本體(ti)(ti)、保(bao)護系(xi)統(tong)、壓縮空氣(qi)系(xi)統(tong)、控制系(xi)統(tong)等組成(cheng)。鍋(guo)爐除(chu)塵器的(de)(de)凈(jing)化方式為外濾(lv)(lv)式,含(han)塵氣(qi)體(ti)(ti)由(you)導流(liu)管進入各單元過濾(lv)(lv)室(shi)并(bing)通(tong)過設置于灰(hui)斗(dou)中(zhong)(zhong)的(de)(de)煙(yan)(yan)氣(qi)導流(liu)裝置;由(you)于設計(ji)中(zhong)(zhong)袋(dai)(dai)離進風(feng)口上口垂直(zhi)距離有足夠、合理的(de)(de)凈(jing)空氣(qi)流(liu)通(tong)適當導流(liu)和自(zi)然(ran)流(liu)向分布(bu),達到整個過濾(lv)(lv)室(shi)內(nei)氣(qi)流(liu)分布(bu)均勻,含(han)塵氣(qi)體(ti)(ti)中(zhong)(zhong)的(de)(de)顆粒粉(fen)塵通(tong)過自(zi)然(ran)沉降分離后直(zhi)接落如(ru)灰(hui)斗(dou)、其(qi)余粉(fen)塵在導流(liu)系(xi)統(tong)的(de)(de)引導下,隨(sui)氣(qi)流(liu)進入中(zhong)(zhong)箱體(ti)(ti),過濾(lv)(lv)后的(de)(de)潔凈(jing)氣(qi)體(ti)(ti)透過濾(lv)(lv)袋(dai)(dai)經(jing)上箱體(ti)(ti)、排風(feng)管排出。
