Problems solved by technology
At present, there are two mainstream seawater desalination methods in the market. The other is distillation, which has a complex equipment structure, high operating costs, and a large area; the other is reverse osmosis, which requires high-pressure equipment and regular cleaning of the membrane structure. Less than 80% utilization
These factors have greatly limited the supply of hydropower in the sea and offshore areas

Abstract
The invention discloses a seawater evaporation water-taking power generation device and water-taking power generation method based on solar energy. In the device, a fresh water tank hermetically communicates with a seawater tank through a water collecting flow channel, and the water collecting flow channel is higher than the seawater surface and the fresh water surface; a cation exchange membranecomprises a semiconductor film main body for generating a photoelectric poisson effect, nanoparticles arranged on the first side, facing a high-transmittance flat plate, of the semiconductor film mainbody, and a capillary water delivery conduit for delivering seawater from the second side to the first side; the semiconductor film main body is provided with a cation selective channel; sunlight irradiates the cation exchange membrane and the nanoparticles through the high-transmittance flat plate, so that the first temperature, the first seawater concentration and the first potential of the first side are higher than the second temperature, the second seawater concentration and the second potential of the second side, the evaporated seawater enters the fresh water tank through the water collecting flow channel after being condensed, and cations directionally migrate from the first side to the second side through the cation selective channel to form ionic current.
Description
technical field [0001] The invention relates to the technical field of seawater desalination and power generation, in particular to a solar energy-based seawater evaporation water intake power generation device and a water intake power generation method. Background technique [0002] As a treasure trove of resources that is being vigorously developed, the ocean not only provides various forms of energy, including salinity energy, wind energy, wave energy, tidal energy, etc., but also a huge treasure trove of water resources. On the other hand, due to unfavorable factors such as inconvenient transportation and remote location in the sea surface and offshore areas, it is still difficult to obtain electricity and fresh water resources needed for production and life. In order to meet the power and water supply needs under such special environmental conditions, various technologies are currently being developed or put into use. [0003] In order to meet the power supply demand, ...
