摘要
随着氢能源在冶金化工生产过程中广泛应用和氢冶金技术的快速发展,氢基竖炉直接还原铁已成为国内外绿色低碳冶金新技术领域的研究热点,然而,氢基竖炉内存在物理能和化学能严重不匹配、气体利用率低、炉顶还原势高等问题,针对上述问题,就氢基竖炉反应器还原域传输特性行为,通过还原理论分析、静态模型结合数值模拟的方法,在还原需气量、反应器内还原气运动规律以及其内温度分布方面展开了相关研究,相关模拟研究结果可为氢基竖炉反应器的设计和操作优化提供参考。
With the wide application of hydrogen energy in metallurgical engineering process and the rapid development of hydrogen metallurgy technology,the direct reduction iron produced from hydrogen-based shaft furnace has become a research hotspot in the field of green and low-carbon metallurgical new technology worldwide.However,there are still many problems in the hydrogen-based shaft furnace,such as serious mismatch between physical and chemical energy,low gas utilization rate and high reduction potential of furnace top.Through the reduction theoretical analysis,static model combined with numerical simulation,relevant studies were carried out on the reduction gas demand,the reducing gas movement behavior and its internal temperature distribution in the reactor.The relevant simulation results could provide references for the design and operation optimization of the hydrogen-based shaft furnace reactor.
