Problems solved by technology

[0003] Nowadays, seawater desalination methods are divided into freezing method, electrodialysis method, distillation method, and reverse osmosis method. Among them, the freezing method consumes a lot of energy, and the fresh water obtained has a bad taste and is difficult to use. The energy consumption of electrodialysis method is very serious, so It is rarely used in the market. The reverse osmosis method is prone to fouling, and it is inconvenient to clean and maintain. The distillation method consumes a lot of energy. However, if the seawater is desalinated by solar energy, it can solve the problem of serious energy consumption. Therefore, solar seawater desalination is used in seawater. It is more and more widely used in the field of desalination

Abstract

The invention discloses a device for seawater desalination by using solar energy, and belongs to the field of solar energy utilization and seawater desalination. The device mainly comprises a condensing box, a snake-shaped pipe, a vacuum meter and a liquid level height detection device. The device mainly uses the sun for gathering light, and converts the light into light and heat energy to heat seawater; the evaporation speed of the seawater is improved through vacuum manufacturing; the steam is sufficiently condensed through condensing area increase; in addition, the seawater to be evaporated is heated by sufficiently utilizing steam condensing latent heat; the energy source utilization rate is improved; the seawater input quantity is regulated by using the siphon principle. The device has the advantages that the green and environment-friendly effects are achieved; the labor and the materials are greatly saved.

Description

technical field [0001] The invention relates to the fields of solar heat collection and desalination of seawater, in particular to a device for desalination of seawater by utilizing solar energy. Background technique [0002] Fresh water is one of the basic materials for the survival and development of human society, and directly affects everyone's health and national economic construction. However, seawater with too high salinity to drink or irrigate directly accounts for 97% of the total water on the earth. above. Therefore, in order to increase the supply of fresh water, an advantageous way is to desalinize sea water or brackish water. [0003] Nowadays, seawater desalination methods are divided into freezing method, electrodialysis method, distillation method, and reverse osmosis method. Among them, the freezing method consumes a lot of energy, and the fresh water obtained has a bad taste and is difficult to use. The energy consumption of electrodialysis method is very ...
