[Abstract]:Seawater desalination technology is an important way to solve the increasingly severe shortage of fresh water resources. As a new type of desalination technology, reverse osmosis seawater desalination technology has developed very rapidly since it came into being. The desalination project using reverse osmosis technology is increasing year by year. The problem of this technology is that the water production cost is on the high side. The optimal design of reverse osmosis seawater desalination membrane system can effectively reduce the energy consumption of water production. Reverse osmosis desalination system is a typical process industry system. The purpose of this paper is to find out the optimal process design of membrane system and desalination system running state in order to achieve the lowest water production cost. The research contents mainly include the following aspects:. Aiming at the optimal design of reverse osmosis seawater desalination membrane system, the traditional optimization method of membrane system is transformed, and the mathematical model with the lowest energy consumption for water preparation is obtained. Firstly, according to the process characteristics of reverse osmosis seawater desalination membrane system, The mathematical model of the process unit is established and the reverse osmosis process is simulated by the model. Secondly, the investment cost of the equipment and the energy consumption cost during the operation of the system are taken as the decision variables to establish the economic model of reverse osmosis seawater desalination. Based on the process model and the economic model, the optimization design model is established for the first stage process and the first stage process respectively, the optimal objective function, the constraint relation and the optimization variable are established. The optimal design process of reverse osmosis seawater desalination membrane system is determined by using GAMS software to solve the optimal design model, and the annual energy consumption cost is obtained. This paper studies the design of membrane system under different conditions, and obtains the optimal design scheme of membrane system under different conditions. The energy consumption cost of tons of water is lower than the actual value of the project, which shows that the optimized design scheme is effective. Aiming at the optimal operation and dispatching of reverse osmosis seawater desalination system, this paper applies the branch and bound method, which is widely used in power dispatching field, to solve the optimal dispatching model. Firstly, based on the analysis of different prediction methods, According to the characteristics of the historical water consumption data in Liuheng Island, the method of autoregressive moving average prediction is used to predict the water consumption in the future dispatching period. Secondly, on the basis of obtaining the predicted water consumption, According to the process characteristics and operation state of the desalination system, the water supply plan of the production pool and the start and stop plan of the desalination unit are taken as the decision variables, and the scheduling model with the objective function of minimizing the running cost is established. The branch and bound method is used to solve the optimal scheduling model. Through the analysis of scheduling examples, the optimal scheduling scheme can effectively reduce the running cost of the system. On the basis of the above research work, combined with the process characteristics of desalination system, the optimal dispatching system of reverse osmosis seawater desalination is designed and developed on the platform of .net with C # language. The requirement and feasibility of the system software realization are analyzed. This paper introduces the overall design framework of the system software, mainly analyzes and explains the realization methods of each functional module, and expounds the testing method and flow chart of the system software. The system can predict the future water consumption according to the historical data, carry out optimal scheduling, and generate reasonable water production plan and water supply plan.
