Problems solved by technology

However, after the water evaporates, the high salt concentration may cause the solar thermal film to block and affect further evaporation, and the efficiency of relying on the solar thermal film to absorb solar energy to heat water is low, which cannot meet the actual demand. These are the important factors that restrict the application of solar energy. factor

Embodiment Construction

[0021] The present invention discloses a solar-driven photothermal-salt difference power generation coupling synergistic interface evaporation system. The specific implementation of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0022] figure 1 Schematic diagram of the interfacial evaporation system for solar-driven photothermal-salt difference power generation coupling efficiency. The system of the present invention includes a light concentrating film, a solar thermal film, a salinity difference power generation module, and a collection and storage device.

[0023] The upper part of the system is equipped with a concentrating film to collect sunlight and improve the utilization efficiency of solar energy in the entire system. When sunlight hits the system from above, most of the sunlight can be injected into the system due to the function of the light-concentrating film, so as to maximize the input of initial energy a...

Abstract

The invention provides a solar-driven photo-thermal-salinity gradient power generation coupling synergistic interface evaporation system. The system comprises a light condensation film, a solar photo-thermal film, a salinity gradient power generation module and a collection and storage device, wherein the solar photo-thermal film is used for evaporating the seawater, so that the salt difference power generation module generates power by utilizing the concentration difference generated in the evaporation process and feeds back electric energy in situ to Joule to heat the solar photo-thermal film, and thereby the evaporation temperature of the solar photo-thermal film is increased, and the evaporation efficiency of the process is further improved; the storage device is used for collecting steam or condensate water generated by solar evaporation. Compared with the prior art, the solar photo-thermal conversion and utilization efficiency can be remarkably improved through the solar evaporation coupling salinity gradient power generation technology; the system is expected to be applied to the fields of sea water desalination, waste heat utilization, renewable energy power generation andthe like in a large scale.

Description

technical field [0001] The invention belongs to the field of renewable energy, and in particular relates to an interface evaporation system driven by solar energy to couple and increase efficiency of photothermal-salt difference power generation. Background technique [0002] With the development of economy and technology in today's world and the progress of human society, the contradiction between energy and environment has become increasingly intensified. All over the world, governments of various countries have formulated strategic plans for renewable energy to deal with the possible depletion of fossil fuels in the future. . As a new type of energy, solar energy has many advantages such as clean and non-polluting, large total resources, easy access, and wide distribution, so it has extremely important applications in many fields. However, the utilization of solar energy is not sufficient so far, and there are still defects such as difficult storage and low utilization e...
