摘要: 深入探讨了ZnO浆液直接吸收SO2的机理,提出了ZnO浆液间接脱硫工艺并分析了机理,实验研究了浆液固含量、液气比及入口SO2体积分数、空塔气速等因素对脱硫效率的影响。

Abstract: The mechanism of absorption of SO2 by ZnO slurry was investigated,and a novel indirect desulfurization process using ZnO slurry was proposed in order to avoid plugging. Based on experiments,the influence of slurry concentration,liquid-gas ratio,SO2 inlet concentration and superficial velocity on desulfurization efficiency was analyzed.
