Embodiment 1

[0018] Such as figure 1 As shown, the integrated seawater desalination concentrated water zero discharge and unstable renewable energy stable power generation device involved in this embodiment includes a wind power generation module, a grid power distribution system, an electrodialysis seawater desalination module, a concentrated seawater storage tank, and a freshwater storage tank. Pool, reverse electrodialysis power generation module and intelligent control system; the wind power generation module uses the existing wind power generation technology to generate electric energy; the power grid power distribution system converts, outputs and / or distributes the generated electric energy, and finally supplies it to power users In use, the power grid power distribution system specifically refers to the line equipment that direct current is transmitted to the electricity users; the electrodialysis seawater desalination module realizes the concentration and desalination of seawater, ...

Embodiment 2

[0027] The difference between this embodiment and Embodiment 1 is that the reverse osmosis seawater desalination module replaces the electrodialysis seawater desalination module, the solar power generation module replaces the wind power generation module, and the others are the same.

[0028] The all-weather solar / wind power generation and zero concentrated water seawater desalination integrated process of the present invention has excellent technical promotion value and social benefits for overcoming the technical disadvantages of renewable energy and reducing environmental hazards caused by seawater desalination concentrated water discharge.

Abstract

The invention discloses a method and device integrating sea water desalination concentrated water zero discharge and unstable renewable energy source for stable power generation, and relates to unstable renewable energy power generation process, electrodialysis seat water desalination process and inverse electrodialysis osmotic energy power generation process. Insufficient power generation quantity of an unstable renewable power generation module is made up by coupling an inverse electrodialysis osmotic energy power generation module and the unstable renewable power generation module, and meanwhile, the concentrated water generated during the sea water desalination process is processed; the residual power generation quantity of the unstable renewable energy source is consumed by storage of a seat water desalination module; and the process is ingenious in design idea, the energy source utilization ratio is high, 24-hour all-weather stable power generation is achieved, and the device and the method have extremely good technical promotion value and social benefit.

Description

technical field [0001] The invention discloses a method and device for integrating seawater desalination concentrated water with zero discharge and unstable renewable energy for stable power generation, and specifically relates to wind energy / solar power generation process, electrodialysis seawater desalination process and reverse electrodialysis salt differential energy power generation process. Background technique [0002] Under the background of global energy crisis, environmental crisis and water resources crisis, the coupling technology of renewable energy and seawater desalination will greatly solve the disadvantages existing in the development process of current seawater desalination technology and renewable energy utilization technology: energy-intensive If the seawater desalination technology uses conventional energy (oil, coal, natural gas and other non-renewable energy sources), although it can effectively alleviate the shortage of fresh water resources to a certa...
