Problems solved by technology
Most of the salinity energy is used for power generation, and reverse electrodialysis is one of the main methods to convert the salinity energy into electrical energy, but the power density of the existing method is relatively low, and the structure of the reverse electrodialysis (RED) module is complex and the water consumption is high. Large, need to constantly replenish fresh concentrated fresh water and other problems, and reverse electrodialysis has relatively high requirements for ion exchange membranes, resulting in high cost of power generation through reverse electrodialysis
[0003] However, the existing energy conversion devices mainly focus on directly converting the salt difference energy into electrical energy, which limits their transmembrane current flux and output power density.

Abstract
The disclosure discloses a solar energy-assisted enhanced salinity cycle power generation system, including: a power generation device and an auxiliary power generation device; wherein, the power generation device includes multiple low-salt liquid chambers, multiple high-salt liquid chambers, multiple cation-selective nano-films and multiple Anion-selective nano-films; the low-salt solution chambers and the high-salt solution chambers are arranged alternately, and the number of the low-salt solution chambers is one more than the number of the high-salt solution chambers or the number of the high-salt solution chambers One more than the number of the low-salt solution chambers; the number of the plurality of cation-selective nano-films and the anion-selective nano-films is the same, and are alternately arranged in adjacent low-salt solution chambers and high-salt solution chambers between; the auxiliary power generation device includes a movable shading plate for blocking a part of the cation-selective nano-film and the anion-selective nano-film, so that sunlight can affect the cation-selective nano-film and the anion-selective nano-film Another portion of the anion-selective nanofilm is irradiated.
Description
technical field [0001] The disclosure belongs to the technical field of salinity difference power generation, and in particular relates to a solar energy-assisted enhanced salinity difference cycle power generation system and method. Background technique [0002] The traditional mainstream power generation methods have disadvantages such as low power generation efficiency, environmental pollution and non-renewable. Therefore, strengthening the recycling of new energy and seeking the coordinated development of energy economy and environmental protection are exactly the problems we are facing. Salt difference energy, as a kind of blue energy, is clean and renewable, and it is also a renewable energy with the highest energy density in ocean energy. Most of the salinity energy is used for power generation, and reverse electrodialysis is one of the main methods to convert the salinity energy into electrical energy, but the power density of the existing method is relatively low, ...
