[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.
