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)氣(qi)(qi)通過進(jin)(jin)煙(yan)(yan)道(dao)進(jin)(jin)入(ru)(ru)(ru)，在(zai)喉部的入(ru)(ru)(ru)口被(bei)(bei)(bei)水(shui)(shui)(shui)(shui)(shui)均(jun)勻的噴(pen)(pen)入(ru)(ru)(ru)，由(you)于煙(yan)(yan)氣(qi)(qi)高速運動，因此(ci)噴(pen)(pen)入(ru)(ru)(ru)的水(shui)(shui)(shui)(shui)(shui)被(bei)(bei)(bei)其融(rong)化成(cheng)細(xi)小的水(shui)(shui)(shui)(shui)(shui)霧(wu)(wu)濕煙(yan)(yan)氣(qi)(qi)中(zhong)的灰料，這樣(yang)，灰料與水(shui)(shui)(shui)(shui)(shui)滴就發生了(le)碰(peng)撞凝聚，尤其是(shi)料徑細(xi)小的灰塵料可以被(bei)(bei)(bei)水(shui)(shui)(shui)(shui)(shui)霧(wu)(wu)水(shui)(shui)(shui)(shui)(shui)溶。達(da)到次(ci)除塵和脫硫，這些為灰料的分離(li)做(zuo)好充(chong)分的準(zhun)備，此(ci)后(hou)進(jin)(jin)入(ru)(ru)(ru)筒體，迅速降低溫度的煙(yan)(yan)氣(qi)(qi)繼續沖擊(ji)池內的石灰水(shui)(shui)(shui)(shui)(shui)，煙(yan)(yan)氣(qi)(qi)中(zhong)的粉(fen)塵和SO2與池中(zhong)的石灰水(shui)(shui)(shui)(shui)(shui)反(fan)應生成(cheng)硫酸鹽，在(zai)慣性力(li)、重力(li)、附著(zhu)力(li)、凝聚力(li)的作用下(xia)沉(chen)入(ru)(ru)(ru)水(shui)(shui)(shui)(shui)(shui)底完成(cheng)第二次(ci)脫硫過程，被(bei)(bei)(bei)煙(yan)(yan)氣(qi)(qi)激起的水(shui)(shui)(shui)(shui)(shui)花，水(shui)(shui)(shui)(shui)(shui)霧(wu)(wu)與洗滌(di)后(hou)的煙(yan)(yan)氣(qi)(qi)在(zai)風機(ji)引力(li)下(xia)，氣(qi)(qi)水(shui)(shui)(shui)(shui)(shui)同(tong)時(shi)抬(tai)開，使煙(yan)(yan)氣(qi)(qi)與石灰水(shui)(shui)(shui)(shui)(shui)充(chong)分反(fan)應，然后(hou)經(jing)葉輪脫水(shui)(shui)(shui)(shui)(shui)器進(jin)(jin)行(xing)氣(qi)(qi)水(shui)(shui)(shui)(shui)(shui)分離(li)，水(shui)(shui)(shui)(shui)(shui)經(jing)泄水(shui)(shui)(shui)(shui)(shui)管流進(jin)(jin)水(shui)(shui)(shui)(shui)(shui)池，并(bing)使煙(yan)(yan)氣(qi)(qi)完成(cheng)第三(san)次(ci)除塵與脫硫，凈化后(hou)的氣(qi)(qi)體經(jing)過風機(ji)排入(ru)(ru)(ru)大氣(qi)(qi)。
