Problems solved by technology

Traditional seawater desalination devices mostly use bulk heating and evaporation technology. Due to the direct contact between the absorber and the water body, most of the heat absorbed by the absorber is quickly lost to the water body in the form of heat conduction, which greatly reduces the steam production efficiency.

Abstract

The invention discloses a solar seawater desalination device capable of realizing fresh water-salt-electricity co-production, and a manufacturing method thereof. The device comprises an evaporation part, a condensation part and an electricity generation part, wherein an interface heating technology is adopted, solar energy is converted into heat energy by utilizing a photothermal conversion material loaded on the surface of a matrix to achieve seawater evaporation and separate out salt at the same time, the condensation part adopts an enhanced heat exchange technology to condense the generatedsteam to obtain fresh water, and the electricity generation part adopts a thermoelectric conversion technology to convert low-grade temperature difference energy inside and outside the device into electric energy and store the electric energy. According to the device, interface heating, enhanced heat exchange and thermoelectric conversion technologies are effectively coupled, so that triple generation of fresh water, salt and electricity can be realized only by taking solar energy as a unique energy source.

Description

technical field [0001] The invention relates to the technical field of seawater desalination, in particular to a solar seawater desalination device capable of realizing freshwater-salt-electricity cogeneration and a manufacturing method thereof. Background technique [0002] Solar energy is an emerging renewable energy, which has the advantages of environmental protection and harmlessness, huge energy, and no need for mining and transportation. Using solar energy to desalinate seawater to obtain fresh water has great application value in solving the problems of high energy consumption, high pollution, and high cost of traditional seawater desalination technology, and has gradually become a research hotspot for scholars. [0003] Commonly used solar desalination devices often have low energy utilization rate during the design and use process, and the cost is far greater than the benefit. To obtain the maximum utilization efficiency, it is necessary to improve all aspects of e...
