摘要:
氧化铝赤泥因排放量大、碱性强,很难被大宗利用；而工业烟气因含大量SO2必须经脱硫达标排放,在分析测试中铝河南分公司联合法赤泥的矿物组成、化学组成、粒径等基础上,采用正交试验法和单因素法在自行设计的吸收塔1 700 mm×60 mm及配套装置中,考察了赤泥的液固比、烟气流量、液气比等因素对烟气中SO2吸收率的影响,对比了各影响因素的显著性,获得了最佳工艺条件:液固比7:1,烟气流量3.6 m3/h,液气比12 L/m3.在此条件下,赤泥吸收烟气中SO,的效率高达95％以上,同时,与热电厂现行的石灰石-石膏湿法脱硫工艺对比,相同条件下赤泥脱硫的效果更好.
Abstract:
Aluminaredmud has not been utilized effectively due to its highemission andstrong alkaline．In— dustrial flue gas whichhas high S02 should be desulfurized to meet up to the standards．The mineral component，chemicalcomposition，grain sizeandmicrostructure ofalumina redmud from Henan BranchofChinaAluminum Co．were determined in this article．The orthogonal experiments and single factor experiments have been done in the self—designed 1700×60mmglass absorption device which accessories were installed in the laboratory．The influential factors such as liquid-solid ratio，flue gasflow，and liquid—gas ratio were examined throughthe orthogonal tests．The optimal conditions：liquid—solid ratio is 7：1(kg／kg)，fluegas flow is 3．6 m’／h liquid-gas ratio and 12 L／m3．Under these conditions．the maximum efficiency ofFGD is more than 95％．At the sametime，compared with the currentlimestone—gypsum wetmethod，underthe same conditions redmudhas a better absorption effects．
