提出高温协同处置集成化治理技术,利用烧结烟气低氧特性、耦合多种工艺实现多污染物协同去除与余热回收。通过构建数学模型与实验研究,明确了低氧烧结烟气对传热系数、燃烧效率及污染物治理效果的影响规律,并优化了工艺设计。结果表明,烧结烟气工况下升/降温反应器传热系数较纯空气条件高20%,优化二次风系统与反应器高度后,CO燃尽率提高了15%以上,为烧结烟气治理提供了新的技术方案与理论支撑。
A high-temperature collaborative treatment integrated governance technology is proposed,which utilizes the low oxygen characteristics of sintering flue gas and couples multiple processes to achieve collaborative removal of multiple pollutants and waste heat recovery.By constructing mathematical models and conducting experimental research,the influence of low oxygen sintering flue gas on heat transfer coefficient,combustion efficiency,and pollutant control effect was clarified,and the process design was optimized.The results showed that the heat transfer coefficient of the heating/cooling reactor under sintering flue gas conditions was 20%higher than that under pure air conditions.After optimizing the secondary air system and reactor height,the CO burnout rate increased by more than 15%,providing new technical solutions and theoretical support for sintering flue gas treatment.
