Abstract

The invention relates to a solar sea water desalinating device which comprises a medium and high temperature solar heat collecting and storing device, a heat exchanging device and a condensation heat transfer device, wherein the medium and high temperature solar heat collecting and storing device is connected with the heat exchanging device, and the heat exchanging device is connected with the condensation heat transfer device by a heat transfer tube. The technology provided by the invention provides the solar sea water desalinating device which carries out desalination of sea water by a combined mode of energy accumulation and photo-thermal conversion, has high solar heat utilization ratio, high water yield, novel structure and low cost, and can operate in all weather.

Description

technical field [0001] The invention provides a seawater desalination device utilizing solar energy technology. Background technique [0002] Fresh water is one of the basic materials for the survival and development of human society. 97% of the total water on the earth is sea water, and fresh water accounts for less than 3%, and the distribution is extremely uneven. The total amount of water resources in my country ranks sixth in the world, but the per capita water resources are only 1 / 4 of the world's per capita water resources. It is listed by the United Nations as one of the 13 countries with the poorest water resources. [0003] With the rapid increase of the world's population and the rapid development of modern industry, the demand for fresh water has increased sharply, and due to the massive discharge of industrial waste, the original clean water has been seriously polluted, which has further aggravated the contradiction of human fresh water supply. The shortage of...
