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)氣(qi)(qi)(qi)(qi)通過進(jin)(jin)煙(yan)道進(jin)(jin)入(ru)(ru)(ru),在(zai)喉部的入(ru)(ru)(ru)口被(bei)(bei)水(shui)(shui)(shui)(shui)(shui)均勻(yun)的噴入(ru)(ru)(ru),由于煙(yan)氣(qi)(qi)(qi)(qi)高速運動,因此噴入(ru)(ru)(ru)的水(shui)(shui)(shui)(shui)(shui)被(bei)(bei)其融化成細小的水(shui)(shui)(shui)(shui)(shui)霧(wu)濕(shi)煙(yan)氣(qi)(qi)(qi)(qi)中(zhong)(zhong)(zhong)的灰(hui)料(liao)(liao)(liao),這樣,灰(hui)料(liao)(liao)(liao)與(yu)(yu)水(shui)(shui)(shui)(shui)(shui)滴就發生(sheng)了碰(peng)撞凝(ning)聚(ju),尤(you)其是料(liao)(liao)(liao)徑細小的灰(hui)塵(chen)料(liao)(liao)(liao)可以被(bei)(bei)水(shui)(shui)(shui)(shui)(shui)霧(wu)水(shui)(shui)(shui)(shui)(shui)溶(rong)。達(da)到次(ci)(ci)除(chu)塵(chen)和(he)脫硫(liu),這些為灰(hui)料(liao)(liao)(liao)的分(fen)離做好充分(fen)的準(zhun)備(bei),此后(hou)進(jin)(jin)入(ru)(ru)(ru)筒(tong)體,迅速降低溫度的煙(yan)氣(qi)(qi)(qi)(qi)繼續沖擊池(chi)內的石灰(hui)水(shui)(shui)(shui)(shui)(shui),煙(yan)氣(qi)(qi)(qi)(qi)中(zhong)(zhong)(zhong)的粉塵(chen)和(he)SO2與(yu)(yu)池(chi)中(zhong)(zhong)(zhong)的石灰(hui)水(shui)(shui)(shui)(shui)(shui)反(fan)(fan)應(ying)生(sheng)成硫(liu)酸鹽,在(zai)慣性(xing)力、重力、附(fu)著力、凝(ning)聚(ju)力的作用下沉入(ru)(ru)(ru)水(shui)(shui)(shui)(shui)(shui)底完成第二次(ci)(ci)脫硫(liu)過程,被(bei)(bei)煙(yan)氣(qi)(qi)(qi)(qi)激(ji)起的水(shui)(shui)(shui)(shui)(shui)花(hua),水(shui)(shui)(shui)(shui)(shui)霧(wu)與(yu)(yu)洗滌(di)后(hou)的煙(yan)氣(qi)(qi)(qi)(qi)在(zai)風機引力下,氣(qi)(qi)(qi)(qi)水(shui)(shui)(shui)(shui)(shui)同時(shi)抬開,使煙(yan)氣(qi)(qi)(qi)(qi)與(yu)(yu)石灰(hui)水(shui)(shui)(shui)(shui)(shui)充分(fen)反(fan)(fan)應(ying),然后(hou)經葉(xie)輪脫水(shui)(shui)(shui)(shui)(shui)器進(jin)(jin)行氣(qi)(qi)(qi)(qi)水(shui)(shui)(shui)(shui)(shui)分(fen)離,水(shui)(shui)(shui)(shui)(shui)經泄水(shui)(shui)(shui)(shui)(shui)管流進(jin)(jin)水(shui)(shui)(shui)(shui)(shui)池(chi),并(bing)使煙(yan)氣(qi)(qi)(qi)(qi)完成第三次(ci)(ci)除(chu)塵(chen)與(yu)(yu)脫硫(liu),凈化后(hou)的氣(qi)(qi)(qi)(qi)體經過風機排入(ru)(ru)(ru)大氣(qi)(qi)(qi)(qi)。
