[0058] Specific implementation plan three: combination Figure 1 to Figure 7 As shown, the double-layer condensation cover 4 is connected to the evaporation pool 2 through a sealing gasket 26. The double-layer condensation cover 4 is a sloping roof structure, including two connected condensation covers, and a cavity is formed between the two layers of condensation covers. The outer layer condensation cover of the double-layer condensation cover 4 is connected with the evaporation pool 2 by a sealing gasket 26, and the two layers of the double-layer condensation cover are communicated at the top of the ridge. In time, part of the water vapor will flow into the cavity of the two layers for further condensation, which increases the temperature difference between the inside and outside, and at the same time reduces the pressure caused by a large amount of water vapor to improve the condensation effect. The cavity of the outer condensation cover and the inner condensation cover The...

Abstract

The invention provides a solar seawater desalination and collection device and method based on an interface evaporation principle, and belongs to the field of seawater desalination. The problems that a conventional desalination method consumes much energy and easily causes environmental pollution, and an existing seawater desalination and collection device is high in manufacturing cost and low in desalination efficiency are solved. A solar power supply device, a seawater supply and hydrothermal circulation device, an evaporation and condensation device and a water storage device are arranged on the main support, the seawater tank and the evaporation pond are connected through a first heating pipe and a second heating pipe, a U-shaped pipe, a gradient water conveying groove, a double-layer condensation cover and an evaporator are arranged in the evaporation pond, and the water storage device comprises a fresh water collecting box and a waste water collecting box. Seawater is circularly heated through heat circulation and the evaporator to generate water vapor, and the water vapor is condensed into liquid drops on the surface of the double-layer condensation cover and is collected into the fresh water collection tank through the gradient water conveying groove and the U-shaped pipe. The solar seawater desalination device is simple in structure and easy to move, and has the advantages of reduction of carbon emission, small pollution and efficient utilization of resources.

Description

technical field [0001] The invention relates to the technical field of seawater desalination devices, in particular to a solar seawater desalination collection device and method based on the principle of interface evaporation. Background technique [0002] The shortage of fresh water resources has always been a problem faced by human beings, especially in remote mountainous areas and islands where electricity is scarce. Solar seawater desalination technology is of great significance to solve the desalination of brackish water in islands with shortage of freshwater resources, remote water-scarce areas and inaccessible power resources. With the rapid development of the world economy, the population and cities are increasing and expanding day by day, the poor management of fresh water resources and water pollution have caused the shortage of fresh water resources. As one of the most important and effective ways to obtain fresh water, desalination and collection of seawater ado...
