工作原理
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(jiang)液制備系(xi)統(tong)(tong)(tong)(tong)(tong)、堿液制備系(xi)統(tong)(tong)(tong)(tong)(tong)、脫硫塔系(xi)統(tong)(tong)(tong)(tong)(tong)、除霧系(xi)統(tong)(tong)(tong)(tong)(tong)、脫硫產物除水系(xi)統(tong)(tong)(tong)(tong)(tong)、電(dian)控(kong)系(xi)統(tong)(tong)(tong)(tong)(tong)、檢測系(xi)統(tong)(tong)(tong)(tong)(tong)等。
工藝優點(dian)
(1)具有較(jiao)好的經濟(ji)技術指標。運行成本僅為其它工藝的30~70%。
(2)脫(tuo)硫效率高達99.9%以上,可滿足環保SO2排放低于100mg/Nm3的要求(qiu)。
(3)吸收劑價(jia)格便宜(yi)。
(4)技術成(cheng)熟,運行可(ke)靠性高。由于(yu)設置(zhi)了(le)多級(ji)反應吸收裝置(zhi),因此當任何一(yi)臺設備出(chu)現(xian)問(wen)題時,均(jun)有其它設備可(ke)以補足脫硫效率,因此整套(tao)系統(tong)可(ke)以不(bu)間斷地運行。
(5)設備檢(jian)修方便(bian),每層(ceng)噴(pen)(pen)淋,每個噴(pen)(pen)淋管(guan)均可單獨拆卸(xie),可實現在線更換噴(pen)(pen)頭,不需要(yao)停(ting)機更換。
(6)產(chan)生(sheng)的脫(tuo)硫產(chan)物為石(shi)膏,可以綜合利用,無(wu)廢物排出。
