Embodiment Construction

[0027] A method for controlling seawater intrusion by using natural energy, comprising three parts: a floating solar seawater desalination device, a desalinated water source transfer device under the action of wind force, and a coastal aquifer water storage infiltration ditch.

[0028] Among them, the floating solar seawater desalination device includes a condensation plate, a solar heat collector, an empty-bottomed water collection bucket, a condensed water collection device and a rubber floating ring. The device is open-bottomed and floats on the sea surface. It uses solar energy to collect heat to evaporate seawater and filter it to solve the problem of fresh water source. Among them, the empty-bottom water collection bucket is in direct contact with seawater, which is the main seawater inlet channel, and plays the role of water exchange and drainage of filter residues. The ring is embedded in the outer wall of the water collection bucket, and is made of anti-corrosion rubb...

Abstract

The invention relates to the field of solar-powered seawater desalination, and aims to provide a novel device for controlling seawater intrusion. The novel device can effectively utilize sufficient natural energy to desalt seawater for a long time and replenish a water bearing stratum, has low pollution to the surrounding environment, is free of energy consumption and has very high applicability, and the engineering is easy to realize. Therefore, the technical scheme is that the device for controlling seawater intrusion by the natural energy comprises a floating type solar-powered seawater desalination device, a wind-acting desalted water source transporting device and a coastal aquifer stored water permeating ditch, wherein the floating type solar-powered seawater desalination device comprises a condensing plate, a solar thermal collector, an empty-bottom water collecting bucket, condensate water collecting equipment and a rubber floating ring, and adopts a structure opened at the bottom, and the empty-bottom water collecting bucket is directly contacted with seawater, is a main seawater inlet channel and has functions of water volume exchange and filter residue discharge. The device is mainly applied to solar-powered seawater desalination.

Description

technical field [0001] The invention relates to the field of solar desalination of seawater, and the prevention and control measures and methods of seawater intrusion. In particular, it relates to devices that utilize natural energy to control seawater intrusion. Background technique [0002] Seawater intrusion is a special form of groundwater pollution. It is caused by the destruction of the balance between seawater and freshwater caused by the excessive exploitation of groundwater. It will not only increase the salinity of the water body, making it exceed the standard of drinking water and irrigation water, but also cause crisis. Future development and utilization of coastal aquifers. At present, the problem of seawater intrusion has been found in dozens of countries and hundreds of places around the world, such as the Netherlands, Germany, Italy, the United States, India, Japan, and China. The problem of seawater intrusion has brought huge economic losses to the coastal...
