【摘要】：为解决现行固定床稀土氟化炉内因温度分布不均而导致的氟化效果不佳问题,以新型立式氟化炉为研究对象,通过合理简化建立数学物理模型,采用CFD软件对模型进行计算分析,得到了不均匀的反应器温度场;结合传热理论讨论了导致温度场不均匀的主要因素,主要有气体入口直径和物料层厚度。采用单因素分析法对立式稀土氟化炉反应器进行优化分析,研究了反应器内温度场随气体入口直径与物料层厚度的变化规律,并获得最佳入口直径和物料层厚度值。根据优化结果建立几何模型并模拟计算,温度场较优化前有较大改善。
[Abstract]:In order to solve the problem of poor fluorination effect caused by the uneven temperature distribution in the present fixed bed rare earth fluorination furnace, a new vertical fluorination furnace is taken as the research object, and the mathematical and physical model is established through reasonable simplification. The non-uniform temperature field of the reactor is obtained by using the CFD software, and the main factors leading to the uneven temperature field are discussed in combination with the heat transfer theory. The gas inlet diameter and the thickness of the material layer are mainly studied. The variation of temperature field with the inlet diameter of the gas and the thickness of the material layer in the reactor is studied by using the single factor analysis method to optimize the reactor of rare earth fluorination furnace. The optimum inlet diameter and material layer thickness are obtained. Based on the optimization results, the geometric model is established and the simulation results show that the temperature field is better than that before optimization.
