摘要/Abstract

摘要： 钴氨络合剂可同时脱除SO2和NO，对燃煤电厂排放控制有积极意义。在分析钴氨配合物同时脱硫脱硝反应机理的基础上，设计了同时脱硫脱硝实验装置，在反应器中对[Co（ＮＨ3）6]Cl2吸收剂同时脱硫脱硝的影响因素进行实验研究。结果表明：提高[Co（ＮＨ3）6]Cl2的浓度可以提高SO2和NO的去除率；过高温度不利于NO的吸收，实验过程中48 ℃时NO的去除率最高；碱性溶液可促进NO的氧化，但是碱性过强导致配合物不稳定，会降低NO的去除率，实验条件下溶液最佳pH值为9.88。

Abstract: By using cobalt ammonia complexing agent SO2 and NO can be removed simultaneously, which is of great significance for the emission control of coal power plants. Based on the analysis of the reaction mechanism of simultaneous desulfurization and denitrification with cobalt ammonia complexing agent, the experimental device is designed such that the major factors affecting [Co(NH3)6]Cl2 absorbent can be explored. The experimental results show that increasing the [Co(NH3)6]Cl2 concentration can improve the removal efficiency of SO2 and NO while extraordinarily high temperatures are disadvantageous to NO absorption. During the experiment, it is observed that the removal efficiency of NO reaches maximum at the temperature of 48 ℃. In addition, alkaline solutions can promote the oxidation of NO, while too strong alkaline solutions may cause instability of complexes and reduce the NO removal efficiency. Under the experimental conditions the best pH value of solution is 9.88.

Key words: coal-fired power plant, emission control, simultaneous desulfurization and denitrification, cobalt ammonia complexing agent, simulation experiment
