Description

Manufacturing Apparatus for Salt from Sea Water

The present invention relates to a salt production apparatus using sea water, and more particularly, to a salt production apparatus using sea water to produce salt by removing foreign matter from the sea water and heating to separate the water.

In general, to obtain salt, the saltwater is introduced from a salt field, confined in a reservoir and dried naturally with solar heat and wind to obtain salt crystals, or the saltwater is filled in a large pot and the large pot is burned with wood, coal, or oil. There are other methods, such as heating the brine to evaporate it to produce salt.

Salt produced in the salt field is naturally evaporated, and the salt is produced for a long time, causing severe production disruptions due to changes in weather such as rain and snow, and occupying a large area of land to produce salt.

And, the production of salt by heating the large pot with fossil fuel is the method used by the ancestors in the past used for heating, by heating the seawater accommodated in the large pot to about 600 ℃ using fossil fuel to evaporate the water salt Get The use of this method in modern times is undesirable because of the cost of fossil fuels and the secondary loss of environmental pollution associated with the use of fossil fuels, and is not suitable because of the large time required. In addition, since heating the seawater at a high temperature of 600 ℃ generates agglomerated salts, an additional process, such as grinding or grinding the salt mass may be necessary.

In addition, relatively recently, a method of drying seawater by using a nonwoven fabric such as evaporation to obtain salt by evaporating it with natural solar heat and wind has been developed, but it is difficult to remove impurities contained in salt, and hygiene when using the fabric multiple times Problems may arise.
