Facilities for ice desalination and salt production using natural resources

Abstract

The invention relates to a facility for making ice to desalinize and preparing salt by utilizing natural resources. The facility is characterized in that: a freezing pond, a brine sun-curing pond and a crystallizing pond are orderly arranged on a slope beach, wherein the freezing pond is provided with a buoyancy gate comprising a one-side gate, a gas valve and an ejection block; when the spring tide rises, the one-side gate automatically floats, the seawater floods into the ponds, the one-side gate raises along with the water, a handle of the gas valve is in contact with the ejection block, a drainage bolt is rotated and unscrewed, and the water in the one-side gate is automatically sunk to retain the seawater in the ponds. The brine sun-curing pond is provided with a buoyancy gate comprising gates on both sides and a self-locking mechanism, wherein the gates on the both sides are controlled to float and sink by the self-locking mechanism. A drainage channel is arranged on a lowermost position of the freezing pond and communicated with the brine bathing pond, and a brine sun-curing channel is arranged on the lowermost position of the brine sun-curing pond and communicated with the crystallizing pond. The facility for preparing the ice to desalinize and preparing the salt by utilizing the natural resources has the capabilities of basically automatically opening the gates to divert the water and discharging the water as well as making the ice to desalinize and preparing the salt by natural energy.

Description

technical field [0001] The invention relates to the fields of seawater desalination and salt production, in particular to a production facility for desalination of seawater and salt production 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 making 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 natural...
