摘要: 针对吹脱塔内污水温度是影响吹脱法脱氨效率的主要因素,而传统PID控制无法精确控制污水温度的问题,设计了基于PLC的污水温度模糊控制器.该设计在PLC中采用定时中断组织块实现离散论域二维模糊控制,通过改变蒸汽调节阀开度调节蒸汽加入量,进而实现对污水温度的精确控制.实验结果表明,该设计控制精度达1.5℃,可有效提高吹脱法的脱氨效率,且节省成本.Abstract: For Stripping is the main factor of the efficiency of ammonia removal, and the traditional PID control can't get good control on sewage temperature, the sewage temperature fuzzy controller based on PLC was designed.The design adopted the timer interrupt block to implement two-dimensional fuzzy control of discrete domain,and adjusted steam addition amount by changing steam regulation value opening to realized precise control of sewage temperature.The experimental results showed that the practical control precision could reach 1.5℃, the design could effectively improve the efficiency of the deamination of Stripping and cost savings.
