The continuous drying and pyrolysis process of wet cerium oxalate(Ce2(C2O4)3·10H2O)has a direct impact on the properties of CeO2.In this study,a new type of continuous pyrolysis equipment of wet Ce2(C2O4)3·10H2O has been numerically simulated using Fluent 19.0 software.The continuous drying and pyrolysis process of wet Ce2(C2O4)3·10H2O has been deeply studied and the effects of different heating conditions on the temperature field and the material heating process in the equipment have also been analysed.The results indicate that it is the heating power that is an indispensable factor for ensuring the successful completion of drying,pyrolysis and oxidation of the materials,and for meeting the required temperature increases.The assembly methods and installation positions of the electric heaters have a certain impact on the temperature distribution and the heating process of the materials in the equipment,but have little impact on the quality of the final products.The maximum temperature of the heating tubes are above 800℃,so it is recommended to use heat-resistant steel.
