Description

technical field [0001] The invention belongs to the field of seawater desalination and energy saving and emission reduction, and in particular relates to a multi-energy coupling seawater desalination system. Background technique [0002] As a scarce basic resource, fresh water resources have become the focus of attention of countries all over the world. Desalination of seawater is a method of separating salt and water in seawater to obtain fresh water, which can provide a stable supply of fresh water resources. The current conventional seawater desalination technologies mainly include thermal distillation desalination and membrane reverse osmosis desalination. Whether it is thermal method or reverse osmosis, they all consume high-grade energy in exchange for fresh water, and have a strong dependence on high-grade electricity. For now, it is still an energy-intensive industry, and the increasingly tense energy problem is difficult to cope with the growing demand for fresh w...
