A seawater desalination system based on wind-solar hybrid power generation and hydrogen power supply

Abstract

The invention relates to the technical field of seawater desalination, and especially relates to a seawater desalination system based on wind-solar hybrid power generation and hydrogen energy power supply. The seawater desalination system comprises a wind-solar hybrid power generation module, a hydrogen energy power supply module, and a seawater desalination module. The wind-solar hybrid power generation module comprises a wind power generation device, a photovoltaic power generation device, a wind-solar hybrid controller for controlling the wind power generation device and the photovoltaic power generation device, and an energy accumulator, which is electrically connected to the wind-solar hybrid controller. The hydrogen energy power supply module comprises a hydrogen energy electrolytic tank, which is individually and electrically connected to the wind-solar hybrid power generation module and the energy accumulator, a fuel power generator, which is connected to the hydrogen energy electrolytic tank, a PLC controller, which is individually connected to the hydrogen energy electrolytic tank and the fuel power generator, and a water energy recovery device, which is connected to the fuel power generator. The seawater desalination module is connected to the fuel power generator. The wind-solar hybrid power generation module and the hydrogen energy power supply module are used together and directly applied to seawater desalination and the generating efficiency is high.

Description

technical field [0001] The invention relates to the technical field of seawater desalination, in particular to a seawater desalination system based on wind-solar complementary power generation and hydrogen energy power supply. Background technique [0002] As we all know, 71% of the earth's surface is covered by water, and the fresh water resources that can be used for people's lives only account for 2.5% of the total water resources, and the corresponding seawater content accounts for 97.5%. With the rapid development of the world, the demand for water resources, especially fresh water resources, is increasing. Therefore, the scarcity of fresh water resources has become a very serious global problem facing the world today. [0003] In recent years, as more and more countries pay attention to the problem of water scarcity, desalination of seawater is considered the best way to obtain fresh water resources. Seawater desalination is the process of separating the salt and wat...
