循环水加酸智能控制系统的研发及应用OA

Through experimental research on online water quality monitoring technology,suitable online monitoring instruments for circulating water quality were selected from aspects such as high stability,anti-pollution ability,easy maintenance,and cost performance,and a circulating water online monitoring system was developed to realize the phenolphthalein alkalinity of circulating water.Online monitoring of indicators such as total alkalinity and pH.Through research on circulating water dosing control technology,an automatic acid dosing control model with three indicators of circulating water total alkalinity,phenolphthalein alkalinity and pH as the main feedback signals was established.A circulating water diagnosis and prediction system based on deep convolutional neural network technology has been developed to automatically extract real-time water quality data and condenser operating parameters,realize diagnosis and prediction of circulating water fouling and corrosion tendencies,and realize stable control of circulating water concentration ratio,as well as intelligent adjustment of water replenishment and sewage discharge.A prototype of an intelligent device was developed and the industrial application of the intelligent circulating water control and management system was completed in a power plant.The results showed that the error of the acid addition amount of circulating water was between±0.2 times(calculated by pH),and the operation of the circulating water system was realized.Unmanned control,the system's continuous and stable operation time exceeded 720 hours.
