Embodiment Construction

[0011] Such as figure 1 Shown is the sea (salty) waters embodiment of the present invention. The daylighting cover (2) that the double-layer transparent material is made is covered on the foam plastic box (4) without cover floating on the water surface (that is to make up for the missing surface) to form an airtight space——solar collection room, sea (salt) The water evaporation chamber (6) functionally enables the solar energy collection chamber and the sea (salt) water evaporation chamber (6) to have thermal insulation effect. There are some holes on the bottom surface of the foamed plastic box (4) without a cover, and black hydrophilic fiber bundles (3) are placed in the holes. One end of the black hydrophilic fiber bundle (3) is immersed in the sea (salt) water area (10), and the other end extends into the solar energy collection chamber and the sea (salt) water evaporation chamber (6). One deck of black hydrophilic fiber cloth (5) is pasted on the inner bottom surface of...

Abstract

The invention relates to a high-efficiency and energy-saving type solar energy seawater (salt water) desalination technology which belongs to the technical field of solar energy utilization and low-temperature flash evaporation of water. In the invention, aiming at the technical problems of serious heat loss, low desalination (or water condensation) efficiency, poor maneuverability, and the like in the prior art, a heat insulation space which is formed by a light-absorbing shade made of double-layer transparent materials and an uncovered foam plastic box is designed so as to reduce the heat energy loss; fiber bundles provide seawater (salt water) for a solar energy collection chamber and an evaporation chamber by utilizing the tension of water, therefore, a water film which is formed due to the existence of fiber cloth reasonably controls the mass of a heated medium in a desalination device and improves the flash evaporation efficiency; an integrated steam circulating system is built so as to ensure that a condenser is in an appropriate condensing condition, rapidly condenses steam in the solar energy collection chamber and the seawater (salt water) evaporation chamber, enlarges and keeps a relative temperature difference among the solar energy collection chamber, the seawater (salt water) evaporation chamber and the condenser and improves the water condensation efficiency; and the corresponding devices are simple in structures and also high in maneuverability.
