STUDY ON AMMONIA-BASED SIMULTANEOUS DESUFURIZATION AND DENITRIFICATION FOR SINTERING FLUE GAS

摘要: 在鼓泡反应器中进行烧结烟气湿式氨法同时脱硫脱硝的实验研究,考察了添加剂/NO物质的量比、吸收液NH3-NH+4浓度和烟气性质对烧结烟气脱硫脱硝的影响。实验结果表明:随着添加剂/NO物质的量比、烟气温度和NO浓度的增加,脱硝率均呈现先增大后减小的趋势。脱硝率随着吸收液中NH3-NH+4浓度的增大而增大。随着SO2浓度的增大,脱硝率逐渐减小。在所有实验条件下,脱硫率均接近或达到100%。在最佳实验条件下,脱硝率可达61.49%。通过添加添加剂部分氧化烧结烟气,可使烧结烟气湿式氨法脱硫工艺的脱硝率提高20%~30%。

Abstract: Experimental researches of enhancing ammonia-based sintering flue gas simultaneous desulfurization and denitrification were performed in bubbling reactor． Effects of molar ratio of additive to NO，NH3 － NH + 4 concentration in absorbing liquid and properties of flue gas on sintering flue gas desulfurization and denitrification were studied． According to the research results，with increasing molar ratio of additive to NO，flue gas temperature and NO concentration，NOx removal efficiency increased at first，but then decreased with further increase of molar ratio of additive to NO，flue gas temperature and NO concentration． NOx removal efficiency increased with increasing NH3 －NH + 4 concentration in absorbing liquid． Increasing SO2 concentration decreased NOx removal efficiency． Under all experimental conditions，SO2 removal efficiency approached or reached 100%． And under optimal conditions，NOx removal efficiency could reach 61. 49%． NOx removal efficiency of ammonia-based sintering flue gas desulfurization process raised 20% ～ 30% by adding additive to partially oxidize sintering flue gas．
