Abstract

The invention discloses a solar seawater desalination device which comprises a solar collecting lens and a surface evaporation seawater desalination device body. The surface evaporation seawater desalination device body comprises a chain plate type solar thermal collector. The installation position of the chain plate type solar thermal collector is matched with that of the solar collecting lens. An inlet of the chain plate type solar thermal collector is communicated with a seawater storage tank. An outlet of the chain plate type solar thermal collector is communicated with an inlet of a cooler. A freshwater circulating water tank is arranged below an outlet of the cooler. A drain valve is arranged at the bottom of the seawater storage tank. The solar seawater desalination device is of an open structure and has the advantages that the freshwater recovery rate is high, energy efficiency cost is low, the structures of all the parts are simple, installation and maintenance are easy, the service life is long, and manufacturing cost is low.

Description

technical field [0001] The invention relates to the field of seawater desalination, in particular to a seawater desalination device 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. Nowadays, there are many methods of desalination of seawater. Although some methods adopt advanced technology or process to achieve high freshwater recovery rate, the equipment structure is complicated or the cost is high; and some methods need to use non-renewable conventional energy as the drive, so that the system can Consumption costs increase, which is very detrimental to ...
