摘要: 提出了一个移动床还原过程的数学模型,并由实验证实,这一模型也能描述实际工业规模的铁矿石移动床还原反应器.利用此模型对移动床还原过程进行了研究,发现了和经典动力学观点有所不同的有关竖炉和高炉固相区还原过程的一些特点和规律,如:所有因素对还原的影响均减弱;H_2的还原能力并不一定总是优越于 CO;传统的热交换曲线应有所改进;对还原过程的反应空区有了新的解释.
Abstract:The experimentally identified math-model of iron ore reduction in moving bed is developed to describe the practical process in industrial reactor.In comparison with the conventional viewpoint of kinetics,some unsimilarity among feature in solid state reduction process of iron ore in D.R.shaft furnace or in shaft of blast furnace is indicated such as:all factors influencing reduction are weakened, the reducibility of H_2 is not always superior to CO,the conventional gas heating curve would be modified and a new understanding of the reserve zone of reduc- tion process is found.
