鍋爐布袋除塵器是把粉塵從煙氣中分離出來的設備。鍋爐除塵器是鍋爐及工業生產中常用的配套設備。它的功能是將鍋爐燃料,燃燒排放煙氣中的顆粒煙塵加以清除,從而大幅度降低排入大氣層中的煙塵量,這是改善環境污染,提高空氣質量的重要環保設備。
工(gong)作原理
煙(yan)(yan)(yan)氣通(tong)過(guo)(guo)進煙(yan)(yan)(yan)道(dao)進入(ru),在喉部的入(ru)口被水(shui)(shui)(shui)(shui)均勻(yun)的噴入(ru),由于煙(yan)(yan)(yan)氣高速(su)運動(dong),因(yin)此噴入(ru)的水(shui)(shui)(shui)(shui)被其(qi)融化成(cheng)細小的水(shui)(shui)(shui)(shui)霧濕煙(yan)(yan)(yan)氣中(zhong)的灰(hui)料(liao),這樣,灰(hui)料(liao)與(yu)(yu)水(shui)(shui)(shui)(shui)滴就發生(sheng)了(le)碰撞凝(ning)聚,尤其(qi)是(shi)料(liao)徑細小的灰(hui)塵(chen)料(liao)可以被水(shui)(shui)(shui)(shui)霧水(shui)(shui)(shui)(shui)溶。達到次(ci)除(chu)塵(chen)和(he)脫(tuo)硫,這些為灰(hui)料(liao)的分離做好充(chong)分的準(zhun)備,此后(hou)(hou)進入(ru)筒體,迅速(su)降低溫度的煙(yan)(yan)(yan)氣繼續沖擊池內的石(shi)灰(hui)水(shui)(shui)(shui)(shui),煙(yan)(yan)(yan)氣中(zhong)的粉(fen)塵(chen)和(he)SO2與(yu)(yu)池中(zhong)的石(shi)灰(hui)水(shui)(shui)(shui)(shui)反應生(sheng)成(cheng)硫酸鹽,在慣性力、重力、附著力、凝(ning)聚力的作用下沉入(ru)水(shui)(shui)(shui)(shui)底完成(cheng)第二次(ci)脫(tuo)硫過(guo)(guo)程(cheng),被煙(yan)(yan)(yan)氣激起的水(shui)(shui)(shui)(shui)花(hua),水(shui)(shui)(shui)(shui)霧與(yu)(yu)洗(xi)滌后(hou)(hou)的煙(yan)(yan)(yan)氣在風(feng)機引力下,氣水(shui)(shui)(shui)(shui)同時抬開,使煙(yan)(yan)(yan)氣與(yu)(yu)石(shi)灰(hui)水(shui)(shui)(shui)(shui)充(chong)分反應,然(ran)后(hou)(hou)經(jing)葉輪脫(tuo)水(shui)(shui)(shui)(shui)器進行氣水(shui)(shui)(shui)(shui)分離,水(shui)(shui)(shui)(shui)經(jing)泄水(shui)(shui)(shui)(shui)管流進水(shui)(shui)(shui)(shui)池,并(bing)使煙(yan)(yan)(yan)氣完成(cheng)第三次(ci)除(chu)塵(chen)與(yu)(yu)脫(tuo)硫,凈化后(hou)(hou)的氣體經(jing)過(guo)(guo)風(feng)機排(pai)入(ru)大氣。
