The invention discloses a modeling method of a reverse osmosis seawater desalination system. The modeling method comprises the following steps: establishing an operation cost model of the reverse osmosis seawater desalination system; constructing a dynamic operation model and an operation boundary condition of the reverse osmosis seawater desalination system; and constructing a model of the reverse osmosis seawater desalination system by taking the lowest operation cost model as an objective function and taking the dynamic operation model and the operation boundary condition as constraint conditions. Constructing a mathematical model of the operation cost of the reverse osmosis seawater desalination system, optimizing the operation strategy of the reverse osmosis seawater desalination system, and reducing the operation cost; factors influencing the operation cost, such as the chemical treatment investment cost, the operation cost of a low-pressure centrifugal pump in the water taking process, the operation cost of equipment in the reverse osmosis process, the fixed investment cost of a reverse osmosis membrane, the system maintenance cost and the labor cost, are integrated in the dynamic optimization model, so that the optimal operation point of the reverse osmosis seawater desalination system can be accurately found.
Description
technical field [0001] The invention belongs to the technical field of seawater desalination systems, and relates to a modeling method of a reverse osmosis seawater desalination system. Background technique [0002] Seawater desalination is a freshwater resource incremental technology, which has the advantages of no flooding, no immigration, no competition for water, and no impact of climate. important technology. Among them, reverse osmosis seawater desalination has the advantages of high separation efficiency, simple equipment, convenient operation, and low energy consumption. It has become the main technology for seawater desalination in my country and even in the world at this stage. According to the National Seawater Utilization Report released by the Ministry of Natural Resources in January 2020, 12,536 tons / day of new seawater desalination projects were built in 2018, and reverse osmosis technology accounted for 96%. 68.7% of the scale. Although reverse osmosis sea...
