A device for taking water from seawater using solar energy

Abstract

The invention discloses a device for taking water from seawater by using solar energy heat collection, which relates to the technical field of solar energy and includes an evaporation unit and a solar heat collection unit. The solar heat collection unit includes a connected solar heat collection component and a solar heat exchange component; The evaporation unit includes a fresh water collection component and a seawater evaporation component, the fresh water collection component is used to collect the fresh water generated by the seawater evaporation component, and the solar heat collection component is used to absorb the heat energy of the sun. The invention has a reasonable structure, realizes rapid heating and evaporation of seawater to form water vapor, and cools it into water, improves the evaporation effect and evaporation speed, realizes heating by using the reflected light of the sea surface and sunlight, and improves the heating effect of the heat medium in the spiral heating tube , by setting the lower reflector and the upper reflector, the sunlight is further collected, the heating effect is further improved, and the utilization rate of solar energy is improved.

Description

technical field [0001] The invention relates to the technical field of solar energy, in particular to a device for taking water from seawater by using solar energy to collect heat. Background technique [0002] With the rapid development of modern society and economy, the human demand for energy is increasing. However, the reserves of traditional energy such as coal, oil, and natural gas continue to decrease and become increasingly scarce, resulting in rising prices. At the same time, the environmental pollution caused by conventional fossil fuels is also becoming more and more serious. These greatly limit the development of society and the improvement of human life quality. . Energy issues have become one of the most prominent issues in the contemporary world. Therefore, seeking new energy sources, especially non-polluting clean energy sources has become a research hotspot. [0003] Solar energy is an inexhaustible clean energy with a huge amount of resources. The total ...

Problems solved by technology

There are more than 10,000 islands in China, but most of them are uninhabitable due to the lack of fresh water, and there are less than 500 permanent residents, which restricts the functions of island development and national defense.

[0004] Although the existing solar heat collectors use some solar heat collectors to generate heat to evaporate seawater, and the evaporated water vapor cools down to form fresh water, but these solar heat collectors have complex structures and general heat collection effects, and cannot make full use of solar energy, resulting in some waste of solar energy, and the evaporation rate of seawater is slow, and the effect is general. Therefore, the application provides a device for taking water in seawater using solar heat collection to meet the demand
