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 invention provides a method for making ice and desalinating sea water by using beach, tide and cold. The method is characterized in that a freezing pond is arranged on a sloping beach; gates on the two sides are floated up in sea water when a big tide rises and the temperature of the surroundings is below 0 DEG C, so that the sea water rushes into the freezing pond; when the water level rises continuously, the gates on the two sides fall down automatically so that the sea water is entrapped in the freezing pond; the sea water in the freezing pond is frozen in a season with air temperature blow 0 DEG C; when the air temperature is higher than 0 DEG C, a rising self-locking mechanism is released so that the gates on the two sides float up in the non-frozen sea water; all the non-frozen sea water in the freezing pond flows back to the sea through the gaps of the rising gates on the two sides; then the gates on the two sides are driven to fall down to close the freezing pond; subsequently, the ice in the freezing pond is frozen and thawed repeatedly due to the change of the air temperature of daytime and night, and brine in the ice slowly flows into a brine trough; when the sea level is lower than the brine trough, a drainage port of the brine trough, which is communicated with a sea is opened to discharge the brine into the sea; and the ice in the freezing pond slowly is thawed into fresh water under natural conditions.

Description

technical field [0001] The invention relates to the field of seawater desalination, in particular to a production method 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 di...
