Method and system for using clean energy for conducting sea water desalination

Abstract

The invention relates to a method and system for using clean energy for conducting sea water desalination. The method for using the clean energy for conducting sea water desalination comprises the following steps of (1) transmitting unstable electricity generated by using a clean energy power generation system to electric steam boilers, which use the electricity for generating steam, to generate superheated steam; (2) transmitting the superheated steam to a steam power generation system to output stable electricity; and (3) transmitting the stable electricity to a sea water desalination system, and producing fresh water. The unstable electricity generated by the clean energy power generation system is converted into the high-quality stable electricity through the electric steam boilers andthe steam power generation system, the problem of the unstable electricity generated by the clean energy power generation system is solved, and by supplying the high-quality electricity to the sea water desalination system for sea water desalination work, a stable energy supply environment of the sea water desalination system can be conveniently guaranteed.

Description

technical field [0001] The invention relates to a method and system for desalinating seawater by using clean energy. Background technique [0002] With the growth of modern population and the rapid development of modern industry, the demand for water resources, especially fresh water resources, is increasing. Desalination of seawater is an important way to solve the problem of scarcity of fresh water resources. Traditional seawater desalination is to use coal or Oil is used as an energy source, and with the reduction of coal and oil storage and pollution problems, people are paying more attention to clean energy such as wind energy, solar energy, tidal energy, and ocean current energy. [0003] The application publication number is CN105589331A, and the application publication date is 2016.05.18. The Chinese invention patent application discloses an energy management method for wind-light-pumped-storage-seawater desalination composite system. The relationship between the el...

Problems solved by technology

[0004] However, when the energy management method of the above-mentioned wind-solar-pumped-storage-seawater desalination composite system is in use, the electric energy generated by wind energy and solar energy is directly supplied to seawater desalination and people's life, and due to changes in natural conditions, the electric energy generated by wind energy and solar energy is reduced. The quality is uneven, the voltage and current are unstable, and people's life and seawater desalination operations need continuous and stable power supply. When using tidal energy and ocean current energy to generate electricity, the generated electricity also has problems of uneven quality.
