摘要
针对中水反渗透系统运行操作复杂、自动化程度低的问题,该文设计了一套中水反渗透自动化监控系统。详细分析了预处理、反渗透、药剂投加和清洗等关键工艺环节的自动控制原理,重点阐述了监控系统的硬件配置、PLC及上位监控程序的设计,并成功应用于内蒙某电厂50 t/h中水反渗透水处理项目中。运行结果表明:系统稳定可靠,操作简洁方便,可提高自动化水平,实现无人或少人值守。
In order to solve the problems of the reclaimed water reverse osmosis system,such as complex operation,low degree of automation,this paper designed a set of automatic monitoring system for reclaimed water reverse osmosis.Detailed analysis of the automatic control principles of key process links such as pretreatment,reverse osmosis,dosing and cleaning,emphasizes the hardware configuration of the monitoring system,the design of the PLC and the monitoring program.The system was successfully applied to a 50 t/h reclaimed water reverse osmosis project of a power plant in Inner Mongolia.The operation results show that the system is stable and reliable,and the operation is simple and convenient.It can improve the level of automation and achieve unattended or fewer attendance.
