铁水预处理技术中反应器的设计至关重要。本文采用k-ε湍流模型与颗粒随机轨道模型相结合的两相流动模型,建立了铁水、反应剂的两相流动模型;采用数值模拟的方法研究了涡流反应器内的铁水、反应剂的两相流动特征;揭示了颗粒喷入位置、喷入速度、铁水流速、铁水流量等参数对反应器内两相流动、混合的影响。为连续处理工艺所需反应器的优化设计及工艺过程的研究与实现打下了基础。
The design of the reactor in hot metal pretreatment technology is of crucial importance. In this paper, a two-phase flow model of molten iron and reactant was established by using two-phase flow model combining k-ε turbulence model and particle random orbit model. The two-phase flow model of molten iron and reactant was established. Phase flow characteristics of the reactor. The effects of particle injection position, injection velocity, hot metal flow rate and hot metal flow on the two-phase flow and mixing in the reactor were revealed. It laid the foundation for the optimization design and process research and realization of reactors required for continuous treatment process.
