Embodiment Construction

[0017] The present invention proposes a device that combines solar energy and salt differential energy reverse electrodialysis to generate electricity. In order to make the advantages and technical solutions of the present invention clearer and clearer, the present invention will be further clearly and completely described below in conjunction with specific examples.

[0018] The present invention relates to a power generation system, which is composed of a solar distillation device and a salt difference energy reverse electrodialysis power generation device, wherein the salt difference energy power generation device is as figure 1 As shown, it includes a pool body, which is divided into five areas evenly spaced by a selective permeable membrane, which are seawater pool 1, fresh water pool 2, sea water pool 1, fresh water pool 2 and sea water pool 1, two phases If the adjacent area is a group, the pool body contains two sets of seawater pools and freshwater pools, and a separat...

Abstract

The invention discloses a solar energy and osmotic energy (reverse electro dialysis method) combined power generation device which comprises a solar energy distillation device and an osmotic energy reverse electro dialysis device. The bottom of a pool body of the osmotic energy reverse electro dialysis device is black, light absorption ability of the black is good, the block and an obliquely-arranged light-transmitting plate located at the top of the pool body jointly play the effect to absorb sunlight, and water vapor evaporated from a seawater pool and a fresh water pool is condensed on the light-transmitting plate to flow into the fresh water pool. The solar energy and osmotic energy reverse electro dialysis method combined power generation device has the advantages that due to the fact that fresh water evaporated from the seawater pool flows into the fresh water pool, the power generating process implementation can be retarded in the process, the fresh water salinity of the fresh water pool is improved, the seawater of the seawater pool is reduced, and accordingly osmotic energy generating efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of power generation devices, and in particular relates to a device for generating electricity by combining solar energy and salt difference energy (reverse electrodialysis method). Background technique [0002] In today's world, the population continues to grow, the industry is developing rapidly, and resources are scarce, and the ocean contains a large amount of energy that can be developed. Among the many available ocean energy, the salinity difference energy is favored by researchers for its simple principle and rich resources. , with huge room for development. [0003] Salt difference energy utilizes a certain chemical potential difference energy formed between two kinds of water with different salinity concentrations. Salt difference energy is ocean energy that exists in chemical energy, and it mainly exists at the junction of rivers and seas. The most common methods are osmotic pressure method and rev...
