工作原理(li)
石灰石膏法脫硫法的原理是依據雙堿法脫硫與石灰石膏法脫硫相結合,利用電石渣中含有的OH-與煙氣中的二氧化硫反應,從而進行脫硫,達到排放要求。電石渣脫硫的產物脫硫石膏主要應用于凈水裝置和建筑行業。從而實現電石渣固廢的有效處理。
主要設備
漿液制備系統(tong)(tong)(tong)(tong)(tong)、堿液制備系統(tong)(tong)(tong)(tong)(tong)、脫硫塔系統(tong)(tong)(tong)(tong)(tong)、除霧系統(tong)(tong)(tong)(tong)(tong)、脫硫產物除水系統(tong)(tong)(tong)(tong)(tong)、電(dian)控(kong)系統(tong)(tong)(tong)(tong)(tong)、檢測系統(tong)(tong)(tong)(tong)(tong)等(deng)。
工(gong)藝(yi)優點
(1)具有較好(hao)的經濟技(ji)術指標。運(yun)行成(cheng)本(ben)僅為其它工藝的30~70%。
(2)脫硫效率高(gao)達99.9%以(yi)上,可滿足環保(bao)SO2排放(fang)低于(yu)100mg/Nm3的要(yao)求。
(3)吸收劑價格便宜。
(4)技術成熟,運行可(ke)靠性高(gao)。由于設(she)(she)置(zhi)了多級(ji)反應吸收裝置(zhi),因(yin)此當任何一臺(tai)設(she)(she)備(bei)出(chu)現問題時,均有其它設(she)(she)備(bei)可(ke)以(yi)補足(zu)脫硫效(xiao)率(lv),因(yin)此整(zheng)套系統可(ke)以(yi)不(bu)間斷(duan)地運行。
(5)設(she)備檢修(xiu)方便,每層噴淋,每個噴淋管均可單獨拆卸,可實現在線更換(huan)噴頭,不需(xu)要停機更換(huan)。
(6)產生的脫硫產物為石膏,可以綜(zong)合利用(yong),無廢物排(pai)出。
