Simple solar energy seawater desalination system

Abstract

The present invention relates to a simple solar energy seawater desalination system, which comprises a self-made simple solar cooker, a transparent and inverted funnel, an iron bottom disk and a clean container for receiving fresh water, wherein the self-made simple solar cooker comprises a satellite antenna big pot (light reflection film), a light absorption substance material (light absorption film), and a cooker bracket. According to the present invention, the sphere center of the satellite antenna big pot (light reflection film) is found, the light absorption substance material (light absorption film) is placed at the sphere center position, the cooker bracket is arranged on the material, the iron bottom disk is placed on the cooker bracket, seawater is introduced into the bottom disk, the transparent funnel covers the bottom disk in an inverted manner, sunlight heats the seawater through thermal radiation so as to vaporize the seawater, the desalinated water vapor is condensed into water droplets on the funnel wall, the condensed water droplets flow into the concave grooves on the periphery of the funnel so as to be stored, and after a proper amount of the water is stored, the funnel is flipped, and the purified seawater is directly poured into the container; and the system is simple and practical, and provides advantages of convenience, economy, time saving and labor saving for island residents or offshore residents.

Description

technical field [0001] The invention relates to a device for desalinating seawater by using solar energy, in particular to a simple solar desalination system for desalinating seawater by converting solar energy into heat energy to evaporate seawater. Background technique [0002] Although there are inexhaustible water resources in the ocean, they cannot be directly used as drinking water due to the high salt content. Therefore, seawater desalination projects have been established all over the world. However, due to the relatively high cost of seawater desalination, it has not been widely popularized. But if we can use completely clean solar energy to purify seawater, perhaps this project can be vigorously promoted. [0003] The present invention adopts solar energy, which is a renewable energy source, has many advantages. Generally speaking, solar energy is a clean energy source. Different from conventional energy sources, solar energy is highly energy-efficient, pollutio...
