| 中文摘要 |
| 介绍一种以FeSO4·7H2O作吸收剂、烟气中SO2为原料合成污水处理药剂——聚合硫酸铁的新脱硫工艺,克服石灰法脱硫效率低、副产品无市场等缺点。研究了温度、吸收液的回流比、Fe离子浓度、pH对脱硫效率影响。实验表明:较高的温度和较高的pH值有利于提高脱硫效率,铁离子对SO2有催化作用,回流比应控制在适当的范围之内。 |
| 英文摘要 |
| This paper presents a new desulphurization process with FeSO4 and NaClO3 as absorbents and SO2 in flue gases as raw material to synthesize flocculent agent——polymeric ferric sulfate.The effects of temperature,reflux ratio,concentration of ferric and ferrous ions and pH have been studied.Higher temperature and pH as well as proper reflux ratio in absorbing tower are crucial for sulfur removal.Moreover,ferric ions catalyze the oxidation of sulfur dioxide. |
