Solar water desalination device

Abstract

The invention discloses a solar water desalination device. The device comprises a first water supply device, an evaporation pipeline, a solar light condensation device and a distilled water storage device. An inclined top plate, a to-be-treated water conveying tank and a distilled water collecting tank are arranged in the evaporation pipeline, and the distilled water collecting tank is arranged below the lower end of the inclined top plate and used for collecting distilled water flowing down from the inclined top plate and conveying the distilled water into the distilled water storage device;the to-be-treated water conveying tank is located outside the distilled water collecting tank; a water inlet in one end is connected with the first water supply device, and a discharge outlet in the other end is used for discharging to-be-treated water; the solar light condensation device comprises a condenser lens and an automatic light following system. Visibly, the solar water desalination device collects solar energy in a light condensation mode, the solar energy is used as a heat source, fresh water is produced through the distillation principle, and therefore efficient utilization of thesolar energy and water resources can be achieved, and fossil energy consumption is completely avoided in the working process.

Description

technical field [0001] The invention relates to the technical field of solar energy, in particular to a solar desalination device. Background technique [0002] Water resources and energy are essential and key resources for human social and economic development, among which water resources are basic natural resources and strategic economic resources. Never in history have these two gifts of nature been given such widespread attention and particular concern around the world as they are today. People will soon realize that the freshwater crisis has far more profound impact on human activities than the oil crisis. With the rapid increase of the global population and the rapid development of the economy and society, the human demand for safe and abundant fresh water is increasing, coupled with the uneven distribution of fresh water resources, abnormal changes in the natural climate, the weak awareness of human water conservation and the industrial demand for fresh water resourc...

AI Technical Summary

Problems solved by technology

However, water bodies that cannot be directly drunk or irrigated due to salt or other minerals account for 97.2% of the total water volume, while the remaining 2.8% of fresh water is extremely unevenly distributed, and 3 / 4 of the reserves are frozen at the two poles of the earth In glaciers and alpine regions, the remaining fresh water stored underground is far more than that on the surface, and the fresh water in rivers and lakes that can be directly used by humans is less than 0.36%.

The surge in seawater desalination will inevitably lead to an increase in fossil energy consumption, which will lead to adverse consequences such as environmental pollution and climate warming

Especially for some islands and remote areas, it is unrealistic and impossible to establish a large-scale high-energy-consuming seawater or brackish water desalination system
