Embodiment Construction

[0036] On the coast with cold winter, there are different degrees of icing every year. The ice edge line is parallel to the coastline; for example, the northern part of the Bohai Sea and the Yellow Sea in China, the perennial glacial period is about 3 to 4 months, and the fixed ice width is 0.2 to 2 kilometers during the maximum glacial period; ice thickness: 20 to 40 cm in the north, 10 to 30 cm in the south cm, and has little effect on navigation. There is a saying in the agricultural proverb that "the tide rises on the fifteenth day of the lunar new year, and the beach can be seen everywhere on the twenty-third day of the eighth day". The present invention utilizes the above-mentioned natural phenomenon to implement tidal freezing and desalination of seawater.

[0037] Specific facilities: On sloped beaches, set up freezing pool 1 (see figure 1 , figure 2 ), the height of the dam 3 that constitutes the freezing pool is higher than the highest peak of the local tide over...

Abstract

The present invention relates to a facility for desalting seawater with ice preparation by using beach, tide and cold. The facility is characterized in that an freezing tank is arranged on a sloping beach, and a dam of the freezing tank is provided with a buoyancy gate; the buoyancy gate comprises a bilateral gate, a gas valve, a top block and self-locking mechanisms; in the high flood tide day, the bilateral gate floats in the seawater, the seawater pours into the freezing tank; the water level is ceaselessly increased, and the bilateral gate automatically sinks so as to maintain the seawater in the freezing tank; in a season with the temperature less than 0 DEG C, the seawater in the freezing tank freezes; in a season with the temperature more than 0 DEG C, a rising self-locking mechanism is loosened, and the bilateral gate floats in the non-freezing seawater; all the non-freezing seawater in the freezing tank flows into the sea from the clearance of the floating bilateral gate; then the bilateral gate sinks to close the freezing tank; the ice in the freezing tank repeatedly thaws and freezes under the temperature change condition of day and night, the salt brine in the ice is discharged to the sea; the ice in the freezing tank gradually thaws into fresh water under the natural state.

Description

technical field [0001] The invention relates to the field of seawater desalination, in particular to a production facility for desalinating seawater by using natural energy. Background technique [0002] Seawater desalination has always been a subject of concern. At present, the indirect desalination method of seawater desalination (mainly the method of producing fresh water from sea ice) is particularly concerned by people. Among them, the method of using natural energy to make sea ice and sea ice to make fresh water is most in line with the requirements of environmental protection and is most worthy of promotion. But do not utilize above-mentioned method to carry out large-scale factory production so far. [0003] Patent CN1686839A (method of using natural cold source to make ice to desalinate brackish water), its main feature is to fill natural or artificial ponds with seawater or brackish water taken from the ground, freeze naturally, then collect ice for storage, and ...
