摘要
对不同反应温度和反应时间下脱硫渣中亚硫酸钙的氧化率进行了研究,研究结果表明:在氧气量充足,保持反应时间不变的条件下,提高反应温度能够促进脱硫渣中亚硫酸钙向硫酸钙转化,从能源利用方面综合考虑,最佳反应温度为400℃;在氧气量充足,反应温度恒定,亚硫酸钙氧化率随反应时间增长略有提高,但效果不明显,最佳反应时间为10 min。
The effect of reaction temperature and reaction time on the oxidation rate of CaSO3 in the desulphurization slag was investigated.The results indicated that in the presence of enough O2,the increase of reaction temperature could promote the conversion of CaSO3 to CaSO4,with a constant reaction time,and the best reaction temperature should be 400 ℃.In the presence of enough O2,the CaSO3 conversion rate increased slightly with reaction time,but not effectively,with a constant reaction temperature,and the best reaction time should be 10 min.
