The invention discloses a multi-chamber rotary furnace, which is scientific and reasonable in structure, good in drying effect, low in energy consumption, low in cost, high in efficiency and easy to realize. On this basis, the invention provides a numerical simulation method for performing catalyst particle heating by utilizing the multi-chamber rotary furnace. Computational fluid dynamics software CFX is adopted to perform numerical computation on a heating process of catalyst materials in the gas multi-chamber rotary furnace and an accompanying heat transfer process, so that high cost and technical risks caused by experiments or blind design are avoided to a certain extent; and the method is of a certain guiding significance for actual operation conditions of the multi-cavity rotary furnace. 本发明公开了种多腔回转炉，结构科学合理，干燥效果佳，耗能少，成本低，效率高，易于实现。在此基础上，本发明提供了种利用多腔回转炉进行催化剂颗粒加热的数值模拟方法，采用计算流体动力学软件CFX对燃气多腔回转炉内催化剂物料的加热过程及伴随的热量传递过程进行数值计算，定程度上避免实验或盲目设计导致的高成本和技术风险，对多腔回转炉实际操作条件具有定的指导意义。
