WANG Linglong
Abstract：Aiming at the problem of precise temperature control before the membrane of the underground membrane separation nitrogen heat exchange device,an automatic temperature control system for the nitrogen heat exchange device based on PID technology was designed.Through software program optimization design and real-time adjustment of proportional,integral,and derivative control parameters by the controller,fast response PID parameter self-tuning and high-precision temperature control were achieved.The experiment showed that this system conducted pre-membrane tests at 48 ℃ and 52 ℃ for different types of membranes,with little difference in temperature deviation and stabilization time,and tended to stabilize over time,thus achieving constant temperature control of the pre-membrane temperature of the nitrogen heat exchange device.It has the characteristics of simple and easy to understand algorithm,good stability,fast response and high control accuracy.
