Problems solved by technology

For example, after the water evaporates, the high salt concentration may cause crystallization to block the water delivery channel and affect further evaporation, and the parallel condensation modules during water collection will undoubtedly increase the cost of seawater desalination. These are important factors restricting the application of solar energy and seawater desalination.

Abstract

A solar photo-thermal driven seawater desalination and iontophoresis power generation system and method are disclosed. In the system, a first electrode immersed in seawater is arranged in a first solution chamber, a second solution chamber is connected with the first solution chamber through a cation selective nano-film, a second electrode immersed in seawater is arranged in a third solution chamber, and the third solution chamber is connected with the second solution chamber through an anion selective nano-film. An adjustable shading plate shades the cation selective nano-film to form a firstpreset part of sunlight irradiation and shields the anion selective nano-film to form a second preset part of sunlight irradiation, so that the cation selective nano-film and the anion selective nano-film are respectively under asymmetric illumination to generate a temperature gradient.

Description

technical field [0001] The invention relates to the technical field of seawater desalination and energy conversion and utilization, in particular to a system and method for solar photothermal-driven seawater desalination and iontophoresis power generation. Background technique [0002] As a clean and efficient renewable energy, solar energy has extremely important applications in many fields. However, how to make full use of solar energy and improve its utilization efficiency is still the top priority to solve the energy shortage problem at present. There are three main ways to utilize solar energy: photothermal conversion, photoelectric conversion and photochemical conversion. One of the most important applications of solar thermal conversion is to use solar thermal evaporation to condense to obtain fresh water, which is also an important way to solve the problem of fresh water shortage. Based on this, various 2D and 3D photothermal materials and photothermal structures h...
