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。
工作原理(li)
煙(yan)(yan)(yan)(yan)(yan)(yan)氣(qi)(qi)(qi)通過(guo)進煙(yan)(yan)(yan)(yan)(yan)(yan)道進入(ru)(ru),在(zai)喉部(bu)的(de)入(ru)(ru)口(kou)被水(shui)(shui)(shui)(shui)(shui)均勻的(de)噴入(ru)(ru),由于煙(yan)(yan)(yan)(yan)(yan)(yan)氣(qi)(qi)(qi)高(gao)速運動,因此(ci)噴入(ru)(ru)的(de)水(shui)(shui)(shui)(shui)(shui)被其(qi)(qi)融化成(cheng)(cheng)(cheng)細(xi)小的(de)水(shui)(shui)(shui)(shui)(shui)霧(wu)濕煙(yan)(yan)(yan)(yan)(yan)(yan)氣(qi)(qi)(qi)中(zhong)的(de)灰(hui)料,這樣,灰(hui)料與水(shui)(shui)(shui)(shui)(shui)滴就發生了碰撞凝聚(ju),尤其(qi)(qi)是(shi)料徑細(xi)小的(de)灰(hui)塵(chen)料可以被水(shui)(shui)(shui)(shui)(shui)霧(wu)水(shui)(shui)(shui)(shui)(shui)溶。達(da)到次(ci)除塵(chen)和(he)脫硫,這些為灰(hui)料的(de)分(fen)離做好(hao)充分(fen)的(de)準備(bei),此(ci)后(hou)進入(ru)(ru)筒體(ti),迅速降低溫(wen)度(du)的(de)煙(yan)(yan)(yan)(yan)(yan)(yan)氣(qi)(qi)(qi)繼續(xu)沖(chong)擊(ji)池(chi)內(nei)的(de)石灰(hui)水(shui)(shui)(shui)(shui)(shui),煙(yan)(yan)(yan)(yan)(yan)(yan)氣(qi)(qi)(qi)中(zhong)的(de)粉塵(chen)和(he)SO2與池(chi)中(zhong)的(de)石灰(hui)水(shui)(shui)(shui)(shui)(shui)反應生成(cheng)(cheng)(cheng)硫酸鹽,在(zai)慣性(xing)力(li)、重(zhong)力(li)、附著力(li)、凝聚(ju)力(li)的(de)作用下沉入(ru)(ru)水(shui)(shui)(shui)(shui)(shui)底完成(cheng)(cheng)(cheng)第(di)二次(ci)脫硫過(guo)程,被煙(yan)(yan)(yan)(yan)(yan)(yan)氣(qi)(qi)(qi)激(ji)起的(de)水(shui)(shui)(shui)(shui)(shui)花,水(shui)(shui)(shui)(shui)(shui)霧(wu)與洗滌(di)后(hou)的(de)煙(yan)(yan)(yan)(yan)(yan)(yan)氣(qi)(qi)(qi)在(zai)風(feng)機引力(li)下,氣(qi)(qi)(qi)水(shui)(shui)(shui)(shui)(shui)同(tong)時抬開,使(shi)煙(yan)(yan)(yan)(yan)(yan)(yan)氣(qi)(qi)(qi)與石灰(hui)水(shui)(shui)(shui)(shui)(shui)充分(fen)反應,然(ran)后(hou)經(jing)葉輪(lun)脫水(shui)(shui)(shui)(shui)(shui)器進行氣(qi)(qi)(qi)水(shui)(shui)(shui)(shui)(shui)分(fen)離,水(shui)(shui)(shui)(shui)(shui)經(jing)泄水(shui)(shui)(shui)(shui)(shui)管(guan)流進水(shui)(shui)(shui)(shui)(shui)池(chi),并使(shi)煙(yan)(yan)(yan)(yan)(yan)(yan)氣(qi)(qi)(qi)完成(cheng)(cheng)(cheng)第(di)三次(ci)除塵(chen)與脫硫,凈(jing)化后(hou)的(de)氣(qi)(qi)(qi)體(ti)經(jing)過(guo)風(feng)機排入(ru)(ru)大氣(qi)(qi)(qi)。
