Reflection heat gathering and Fresnel light gathering composite core type solar energy seawater desalination system

Abstract

The invention discloses a reflection heat gathering and Fresnel light gathering composite core type solar energy seawater desalination system, which mainly comprises a water overflow pipe opening, a water containing groove plate, a distilled water outlet, a Fresnel lens, a reflecting mirror, a water absorption core, a tin foil sealing edge, a high-transparency glass cover plate, a seawater pool, awater inlet pipe opening, a seawater desalination device, a valve, a water storage box, a distilled water collecting bottle, an overflow water collecting box, a thick brine flushing pipe opening anda necessary connecting pipeline. After the Fresnel lens receives sun light, large-area sun light is gathered onto the small-area water absorption core; an adsorbed water film in the water absorption core is heated. The reflection mirror receives a part of sun light reflecting to the cavity wall by the Fresnel lens; one part of sun light irradiated by the sun to the cavity wall through the high-transparency glass cover plate is reflected onto the water absorption core through a plane mirror, so that the temperature of the water absorption core is raised. The box body is filled with the glass cotton for heat insulation; the periphery of the device is subjected to heat insulation; temperature differences are formed between the inside of the cavity and the outside; the water steam is formed onthe glass cover plate to be condensed again, so that fresh water is generated.

Description

technical field [0001] The invention relates to a seawater desalination system, in particular to a core solar seawater desalination system combined with reflection heat collection and Fresnel light concentration, belonging to the field of solar heat utilization. Background technique [0002] The water coverage area on the earth is as high as 70.8%, but more than 97% of the water resources contain a large amount of minerals, and the salinity is as high as 30000-4500ppm, which cannot be directly drunk or irrigated. Of the remaining 3% fresh water resources, 3 / 4. The shortage of fresh water resources has become a global problem in frigid zones or glaciers at the two levels of the earth. [0003] Since the 1960s to the present, seawater desalination technology has developed rapidly, and mature methods such as distillation have been widely used in industrial production. At present, there are mainly two types of seawater desalination in my country: thermal method and membrane met...
