The invention discloses a reverse electrodialysis salt-difference energy power generation device without a partition plate. The device takes an ion exchange membrane device as an axis, and is respectively provided with a second gasket, a flow reducing device, a first liner on both sides from the inside to the outside. The gasket, the first cation exchange membrane, the gasket, and the electrodes are connected with an ammeter between the two electrodes, and a voltmeter is connected between the two current reducing devices. The technical solution proposed by the present invention improves the power density and power generation efficiency of the system by combining the structure improvement of the RED device and the optimization of the performance of the ion exchange membrane, thereby accelerating the process of commercial application of reverse electrodialysis power generation.
Description
technical field [0001] The invention belongs to the technical field of salt difference energy power generation equipment, and relates to a separatorless reverse electrodialysis salt difference energy power generation device. Background technique [0002] Salt difference energy is the potential energy existing between two solutions with different ion concentrations. The reverse electrodialysis method uses an ion exchange membrane to separate two solutions of different concentrations, and ions move directionally from a place with a high concentration to a place with a low concentration. Combined with the characteristics of the ion exchange membrane, such as selective permeability, it can effectively penetrate ions, in order to achieve the purpose of generating electricity by using the salt difference energy. [0003] Among the many forms of ocean energy, salinity energy is the most available for power generation. Usually, the potential difference between fresh water and sea ...
