借助HSC软件对除钒浆液制备过程中化学反应过程的模拟,对除钒浆液制备过程进行热平衡计算,包括对除钒系统中化学反应热、物料热量变化、体系散热(系统向反应炉不同部位的传热,反应炉向周围环境的散热)等过程的计算方法进行了详细的推导分析,并结合生产实际,给出了具体的计算方法。结果表明该计算方法能完整地计算出各项热收入与支出,形成一个完整的热平衡体系,以校核反应炉的运行水平,可以作为工业实际生产的辅助计算方法。同时,将未纳入计算的热量控制在2%以内,根据实际生产数据,可以计算出制备的浆液中Ti Cl3和Al Cl3的量,不仅可以验证实际化验结果的准确性,在设备确保完好的时候还可以直接反映出除钒浆液质量的好坏,避免了因为化验时间太长带来的不便,为实际生产提供指导作用。
HSC software was used to simulate the chemical reaction process during the preparation of vanadium-bearing slurry, and the heat balance calculation was carried out on the preparation process of vanadium-bearing slurry, including the chemical reaction heat, the change of material heat, the heat dissipation of the system Heat transfer, heat dissipation from the reaction furnace to the surrounding environment) and other processes are deduced and analyzed in detail, and the specific calculation methods are given according to the actual production. The results show that this calculation method can calculate all the heat revenues and expenditures completely and form a complete heat balance system to check the operation of the reactor, which can be used as a supplementary calculation method for industrial actual production. At the same time, the calorific value not included in the calculation should be controlled within 2%. According to the actual production data, the amount of TiCl3 and AlCl3 in the prepared slurry can be calculated not only to verify the accuracy of the actual test results, but also to ensure that the equipment is in good condition But also can directly reflect the quality of the vanadium slurry, to avoid the inconvenience caused by the long test time, to provide guidance for the actual production.
