Description

Description of the Related Art [0002] Seawater desalination apparatus and bay salt manufacturing method [

The present invention relates to a seawater desalination apparatus and a method for manufacturing a salt of a salt, and more particularly, to a method for producing a salt for producing a salt by evaporating seawater to remove salt from the seawater for use as drinking water, agricultural water, industrial water, .

Generally, the solar salt is concentrated by exposing the salt water supplied to the evaporation paper from the tidal reservoir storing the seawater (sea water) to the sunlight and wind, and concentrating the concentrated saturation function moving from the evaporation paper to the salt plate The salt crystals can be spread out by depositing.

Seawater desalination refers to the removal of various impurities and salts contained in seawater containing saline to obtain fresh water. Sea water desalination methods include evaporation, reverse osmosis, and freezing.

The evaporation method is a method of obtaining fresh water by low-pressure evaporation which evaporates at low temperature by supplying heat to seawater and then reducing the pressure.

The reverse osmosis membrane method is a method for extracting fresh water by filtering an ionic substance dissolved in seawater by a semi-permeable membrane (membrane) in which almost no ionic substance dissolved in water is passed and pure water is passed, And it is widely used because it is easy to operate.

To separate ionic material from pure water in seawater requires high pressure above osmotic pressure, which is called reverse osmosis.

Seawater desalination requires a high pressure of about 42 to 70 bar. The seawater desalination facilities using the reverse osmosis membrane method can be composed of a pretreatment device, a seawater desalination device, and a post-treatment device to remove foreign matter and salt contained in seawater.

The pretreatment device is intended to remove the foreign matter contained in the seawater in advance before removing the salt from the seawater to increase the seawater desalination efficiency.

When the pretreatment step is not carried out, reverse osmosis is required to remove salt from the seawater by the reverse osmosis method, and foreign substances are excessively adhered to the membrane, thereby lowering the permeability of the fresh water through the membrane .

Pretreatment water that has undergone the pretreatment is introduced into desalination reverse osmosis filtration system and separated into desalinated treated water and concentrated water. The concentrated water is discharged and the desalinated treated water is mineralized and sterilized in the post-treatment step, and is put into the final storage tank.

In the desalination process, which removes salt from the seawater, when the osmotic pressure is applied to the seawater, the water passes through the reverse osmosis membrane and is purified. The ions and molecules can not pass through the reverse osmosis membrane and are concentrated.

As the salt is removed from the seawater, the concentration of the seawater becomes higher and higher, so that the water in the seawater can pass through the reverse osmosis membrane only when a higher reverse osmosis pressure is applied.

The salinity of the seawater is about 3.5%. As the salinity is removed from the seawater during the desalination process, the concentration of the seawater increases by 5% to 8%.

In the seawater desalination process, a higher reverse osmosis pressure is required due to an increase in the concentration of seawater, thereby increasing the energy cost.
