摘要

在铁法脱硫的基础上引入过H2O2,对铁粉和H2O2组成的类Fenton体系进行了烟气脱硫研究。利用自行设计的实验室简易鼓泡吸收罐,考察了过H2O2质量浓度、铁粉用量、进口气速和进口SO2体积分数等因素对脱硫效果的影响。实验结果表明,H2O2的质量浓度可低至6g/L;铁粉用量为4.2g/L时处理效果稳定;在气速400L/h下,该法脱硫效果能达到99%以上;SO 2进口体积分数对脱硫效果影响不大。填料塔小试结果与简易鼓泡吸收罐反应结果基本相符。

Abstract

Flue gas desulfurization using iron in Fenton's reagent, Fe/H2O2, to remove SO2 has been demonstrated. The effects of varying the mass concentration of H2O2, dosage of Fe, gas flow rate and inlet volume fraction on desulfurization efficiency were studied using a simple bubbler designed in our laboratory. High desulfurization levels were observed even when the mass concentration ofH2O2was only 6g/L. The optimum dosage of Fe was found to be 4.2g/L. The removal efficiency of SO2 was above 99% when the gas flow rate was 400L/h, and was unaffected by the inlet volume fraction. Similar results were demonstrated in a ring packed tower experiment.
