本發(fā)明涉及一種從氣流中同時去除二氧化硫和氮氧化物脫除劑的制備及脫除方法和裝置，屬于大氣污染控制和環(huán)境保護技術(shù)領(lǐng)域。背景技術(shù)：人類活動產(chǎn)生的二氧化硫(SO2)和氮氧化物(NOx，主要為NO和NO2)有害氣體，由燃料燃燒產(chǎn)生的占90％以上。二氧化硫和氮氧化物對人和生物都有致毒作用，是引起大氣酸雨的主要原因。中國環(huán)境狀況公報統(tǒng)計數(shù)據(jù)表明我國部分城市的酸雨污染性質(zhì)已開始由***型向硝酸根離子不斷增加的復(fù)合型轉(zhuǎn)化(國家環(huán)保部：2010年中國環(huán)境狀況公報)。近年來，國家新制定了一些新的法律法規(guī)，對特別是火電等燃料燃燒過程排放的二氧化硫和氮氧化物等污染物作出了更加嚴(yán)格的控制規(guī)定和減排要求。一般地，火力發(fā)電廠等以化石燃料燃燒產(chǎn)生的煙氣中的二氧化硫濃度約為幾百到幾千mg/m3，石灰/石灰石等堿液吸收法是目前煙氣SO2廢氣治理的主要方法，但濕法吸收需要消耗大量水，設(shè)備投資大，系統(tǒng)復(fù)雜。干法一般是采用爐內(nèi)噴鈣的方式，但爐內(nèi)噴鈣效率不高，并對鍋爐效率有一定影響。燃料燃燒產(chǎn)生的煙氣中的氮氧化物濃度約為幾百到幾千ppm，其中95％以上是一氧化氮，目前選擇性催化轉(zhuǎn)化法(SCR)是目前治理煙氣NOx的主要手段之一，但催化劑對運行條件要求嚴(yán)格，需要氨作為還原劑。合肥高純度硫酸鈉售后無水***鈉，俗稱元明粉，是非常常見的粉末型礦產(chǎn)無機化學(xué)原料。</p><div
