Abstract

The invention discloses a reverse electrodialysis power generation device which comprises a reverse electrodialysis membrane stack, the reverse electrodialysis membrane stack comprises a cathode plate, anion exchange membranes and cation exchange membranes, and an anode plate, the anion exchange membranes and the cation exchange membranes are alternately arranged, the anion exchange membranes andthe cation exchange membranes are spaced through partition plates, and the partition plates comprise partition plate pads. An anode net, an anion exchange net layer, a cation exchange net layer and acathode net are sequentially stacked on each partition plate pad; the partition plate between an anion exchange membrane and a cation exchange membrane is a forward partition plate, the partition plate between a cation exchange membrane and an anion exchange membrane is a reverse partition plate, and the anion exchange net layer is close to the anion exchange membrane; the reverse electrodialysismembrane stack is connected with a concentrated water tank and a fresh water tank, the concentrated water tank is communicated with the forward clapboard, and the fresh water tank is communicated withthe reverse partition plates. The influence of the shadow effect on reverse electrodialysis can be reduced, the ion migration rate is increased by applying an electric field, and the reverse electrodialysis power generation efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of power generation equipment, and relates to a reverse electrodialysis power generation device. Background technique [0002] Salt difference energy is the potential energy between two solutions with different ion concentrations. It is a kind of physical and chemical energy, which mainly exists in river estuaries, inland salt lakes and salt mines. Our country has a vast sea area, a long coastline, many rivers entering the sea, and huge runoff into the sea. There are abundant salinity energy resources near the mouths of the rivers along the coast. Reverse electrodialysis power generation is a new type of renewable, sustainable, green and clean energy that uses salt difference energy to generate electricity. As one of the most promising and potential technologies of salt differential power generation, reverse electrodialysis power generation has higher energy density, stronger operability and lower cost than...
