利用Fluent软件对镍钴冶炼系统产生的废氯气碱液吸收工艺中的吸收塔进行了模拟计算。考察了一定操作条件下吸收塔内气液两相流的速度、压力及氯气浓度分布。模拟计算的数据表明吸收液喷射量的变化对吸收塔出口氯气浓度影响显著,而对塔内压降影响不大,与实验测试值吻合较好,验证了氯气吸收塔气液两相流数学模型的正确性。

Make numerical simulation on chlorine absorption column for nickel & cobalt metallurgical process by using Fluent software. Under the certain operating conditions, the inside tower gas-liquid flow rate, pressure, chlorine distribution were investigated. The data from analog computation shows that the change of absorption liquid emitted dose has great influence on chlorine density of absorption outlet, while it cause a minor impact on tower inside pressure drop. The test result is finely matched with the experimental measurement, which proves the accuracy of mathematical model of gas-liquid two-phase flows in a chlorine absorption tower.
