- 摘要:
- 再生温度是影响分子筛再生效果的关键因素，研究再生工艺过程的温度变化，进而对控制方案进行优化，对提高分子筛脱水装置运行效率及降低能耗有重要意义。为提高自控设计水平，在设计过程中通过建立再生工艺系统内分子筛塔、气体换热器和再生气加热炉等工艺对象的动态数学模型，对整个再生过程温度变化情况动态模拟仿真，探索通过PID参数整定、分子筛塔切换流程优化、前馈反馈控制和智能控制优化控制等方法提高装置运行性能、降低能耗。
Regeneration temperature is the key factor influencing regeneration effect.Taking advantage of simulation technology to research molecular sieve system temperature dynamic change on regeneration process and optimizing control algorithm can improve the performance of molecular sieve regeneration operation and reducing energy consumption.To improve the instrmentation level,dynamic simulation has been conducted for the temperature change of the whole regeneration process by establishing dynamic mathematical model for molecular sieve tower,heat exchanger and heating furnace.There are several optimizing methods,including optimizing PID tunning parameters and the molecular sieve switching sequence,feedforward-feedback controller and intelligent controller.
