高爐煤氣一體化脫硫裝置及方法與流程

本發(fa)明涉(she)及高爐煤氣,具體(ti)涉(she)及高爐煤氣一體(ti)化脫硫裝置及方法。


背景技術:

1、現有煤氣脫硫工(gong)藝(yi)主要采(cai)用(yong)水解催化工(gong)藝(yi)將(jiang)高爐(lu)煤氣中所含的有機硫化物如cos、cs2等有機硫轉變為h2s,之后利(li)用(yong)活性炭吸附原理將(jiang)其吸附,得(de)到凈化后的高爐(lu)煤氣。

2、為了實(shi)現上(shang)述(shu)工藝(yi),現有(you)煤(mei)(mei)氣脫(tuo)硫裝(zhuang)置(zhi)一般根據(ju)其功能拆分(fen)(fen)為多(duo)個結構,分(fen)(fen)布不在各個區(qu)域,彼此之間通(tong)過復(fu)雜(za)的管道相連;存在占地面積廣(guang)、管路走(zou)向(xiang)復(fu)雜(za)的缺點。其次,在現有(you)的脫(tuo)硫系統(tong)重,煤(mei)(mei)氣是通(tong)入(ru)加熱(re)(re)裝(zhuang)置(zhi),然后(hou)加熱(re)(re)至預設溫度(du)后(hou)排出,加熱(re)(re)裝(zhuang)置(zhi)外置(zhi)熱(re)(re)量外散嚴重,對能源消(xiao)耗較大。

3、另外,現有的煤(mei)氣(qi)在(zai)脫硫(liu)系統中的流(liu)向均為立式軸向或者臥式軸向,煤(mei)氣(qi)在(zai)水(shui)解及吸附(fu)單元處(chu)存在(zai)過于(yu)集中在(zai)某(mou)一反(fan)應區域(yu)內,導致(zhi)反(fan)應截面(mian)積過小(xiao),脫硫(liu)反(fan)應效率過低。

技術總結
本發明公開了高爐煤氣一體化脫硫裝置及方法,包括筒狀結構,環形水解層,加熱結構,環形脫硫層,冷卻結構。一是,通過設置環形水解層和環形脫硫層,使得煤氣在水解催化和吸附脫硫過程中均沿徑向流程,增大煤氣在環形水解層和環形脫硫層的流通區域,達到增大反應截面積的目的,最終提高反應效率。二是,將脫硫工藝的冷熱交換、水解、吸附等多個環節均設置在筒狀結構內,極大地減少了設備占地尺寸及規模,提高了裝置的集中度。三是,將加熱結構安裝在環形水解層內側,避免熱量外散至周圍環境空氣中;另外設置隔熱層,避免冷卻結構對上層空間熱量的消耗和上層空間的熱量經過輻射輸入至下層空間;從而達到降低能源消耗的目的。
