摘要：

为了明晰溶液再生温度波动对溶液再生性能的影响规律，建立再生器的动态仿真模型. 搭建溶液再生系统实验台，设计开展溶液再生过程的动态实验，验证动态模型的准确性. 通过仿真模拟分析溶液再生温度的平均温度、波动周期与幅值对再生溶液质量分数极差和平均再生量的影响规律. 结果表明，溶液平均温度对平均再生量的影响最为明显，溶液温度波动幅值对再生溶液质量分数极差的影响最大. 当溶液温度波动周期为0.5 h时，平均再生量随波动幅值的增大而增大；当波动周期为2.0 h时，平均再生量主要受溶液平均温度的影响. 再生溶液质量分数极差在温度波动幅值小时随波动周期的增大而增大，在幅值大时随周期的增大而减小.

Abstract:

A dynamic model of the regenerator was developed to investigate the influence of solution temperature fluctuation on regeneration performance. An experimental platform of solution regeneration system was built to verify the model. The simulation was conducted to investigate the effects of average temperature, fluctuation period, and amplitude of the solution temperature on the range of solution mass fraction and average regeneration rate. Results show that the average temperature of the solution has the most significant impact on the average regeneration rate, while the fluctuation amplitude has the greatest influence on the range of solution mass fraction. When the temperature fluctuation period of the solution is 0.5 h, the average regeneration rate shows an increase with the rise of the fluctuation amplitude. With a fluctuation period of 2.0 h, the average regeneration rate is primarily affected by the average temperature of the solution. The range of solution mass fraction increases with the fluctuation period increases when the temperature fluctuation amplitude is small. Whereas, when the amplitude is large, the mass fraction range exhibits a descending trend with the increase in the period.
Key words: solution regeneration    temperature fluctuation    dynamic performance    regeneration rate
