| 摘 要： | 建立了一套以LiCl水溶液为吸收工质的逆流绝热填料塔吸收除湿装置，在处理空气含湿量为14～20g/kg，处理空气流速为1.0～1.2m/s，空气温度为26.0～34.0℃，溶液入口质量分数为0.340～0.400，溶液入口温度为25.0～34.0℃，溶液入口流量为70～230?L/h的条件下，进行了溶液吸收除湿实验研究，通过改变溶液与空气的入口参数，获得空气出口温、湿度的变化状况。建立了过程的热质传递模型，比较模拟数据与实验数据，验证了理论模型有较好的适用性。应用模型对溶液除湿过程进行了模拟分析，预测了除湿过程的操作优化条件。实验结果与模拟数据对溶液吸收式除湿系统的性能分析与工程设计提供了帮助与指导。

| Abstract: | A countercurrent packed-type tower with lithium chloride as a dehumidifier is described.The influence of varying the solution and the air inlet parameters on the outlet parameters of the air were investigated.A heat and mass transfer model was set up,and the simulation results were found to be in accordance with the experimental data.The model was subsequently used to analyze the process in detail and predict the optimum inlet parameters,which is helpful in terms of improving the engineering design. |
