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(zhu)要設備
漿液制(zhi)備系統(tong)(tong)(tong)(tong)(tong)、堿液制(zhi)備系統(tong)(tong)(tong)(tong)(tong)、脫(tuo)(tuo)硫塔(ta)系統(tong)(tong)(tong)(tong)(tong)、除霧系統(tong)(tong)(tong)(tong)(tong)、脫(tuo)(tuo)硫產(chan)物除水(shui)系統(tong)(tong)(tong)(tong)(tong)、電(dian)控系統(tong)(tong)(tong)(tong)(tong)、檢(jian)測系統(tong)(tong)(tong)(tong)(tong)等。
工藝優點
(1)具(ju)有較好的(de)經(jing)濟技術(shu)指標。運行成本僅為(wei)其它工藝的(de)30~70%。
(2)脫硫(liu)效率高(gao)達99.9%以上,可(ke)滿足環保SO2排放低于100mg/Nm3的要(yao)求。
(3)吸收劑價格便宜。
(4)技術成熟,運行可(ke)靠(kao)性高。由于(yu)設(she)置(zhi)了多(duo)級反應吸(xi)收裝置(zhi),因此當任(ren)何一臺設(she)備出(chu)現(xian)問題(ti)時,均有(you)其它設(she)備可(ke)以補足脫硫效率(lv),因此整套系統可(ke)以不間斷地運行。
(5)設(she)備檢(jian)修方便,每層(ceng)噴淋,每個噴淋管(guan)均可單獨拆(chai)卸,可實(shi)現在線更換噴頭,不需要停機更換。
(6)產(chan)生的脫硫產(chan)物為(wei)石膏(gao),可以綜合利用,無廢物排出。
