ことができる。Description: TECHNICAL FIELD [0001] The present invention relates to desalination of seaweeds, especially kelp. [0002] Conventionally, as a method for desalting kelp, kelp is immersed in water for a long time or immersed in hot water. [0003] When seaweeds are immersed in water for a long time or immersed in hot water, considerable partial desalination can be achieved. In this case, calcium and iron, which are important as foods, are used. Since the iodine and the like also dissolve and lose nutrients, a method for selectively extracting only salt is required. SUMMARY OF THE INVENTION In view of the above circumstances, the present invention selectively extracts only salt without losing nutrients such as calcium, iron, and iodine which are important as foods of kelp. In order to provide a method, two glass fiber diaphragm sheets 1 and 2
The three tanks divided by the positive water tank 3, the central water tank 4, and the negative water tank
The positive electrode water tank 3 has a positive electrode 6 made of a carbon alloy.
And a negative electrode 7 made of gold or platinum is provided in the negative electrode water tank 5.
Seaweeds 8, which are desalination objects, are placed in the central water tank 4.
From the central aquarium 4
The fresh water is injected, and the injected fresh water passes through the diaphragm sheets 1 and 2.
To fill the positive electrode water tank 3 and the negative electrode water tank 5 with the positive and negative electrodes 6 and 7.
When a DC current is connected and the current flows, the hook 9
Salt rapidly dissolves in water from seaweeds 8 suspended by water
However, it is ionized into Na + and Cl - ions,
The tank 5 and the positive electrode water tank 3 are shifted to the negative electrode 7 and the positive electrode tank 3, respectively.
Perform ion exchange in 6 to generate NaOH and HCl,
NaOH and HCl are the flow of fresh water injected into the central water tank 4.
Extruded from drainage ports 10 and 11 of negative electrode water tank 5 and positive electrode water tank 3
However, salt in seaweed is limited to salt due to the difference in ionization intensity.
First electrolysis, desalination in seaweed can be done easily in a short time
The desalination method was used for seaweeds. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to specific embodiments shown in the accompanying drawings. As shown in FIG. 1, the desalination apparatus is composed of three tanks separated by two glass fiber membrane sheets 1 and 2, and comprises a positive water tank 3, a central water tank 4, and a negative water tank 5. ing. The positive electrode water tank 3 is provided with a positive electrode 6 made of a carbon alloy, and the negative electrode water tank 5 is provided with a negative electrode 7 made of gold or platinum. Seaweeds 8 to be desalted are suspended by hooks 9 in the central water tank 4. When fresh water is injected from the central water tank 4, the water also fills the positive water tank 3 and the negative water tank 5 through the diaphragm. When a direct current is connected to the positive and negative electrodes 6 and 7 and a current is supplied, salt is rapidly dissolved in water from the seaweeds 8 suspended by the hook 9 of the central water tank 4, and Na + and Cl are dissolved.
- ionized into ions, respectively shifted to negative water tank 5 and the positive electrode water tank 3, respectively by ion exchange with the negative electrode 7 positive electrode 6, NaOH and HCl occurs, which is the central water tank 4
The water is pushed out from the drainage ports 10 and 11 of the negative electrode water tank 5 and the positive electrode water tank 3 by the flow of the fresh water injected into the tank. Since salt in seaweed is initially electrolyzed only by salt due to the difference in ionization intensity, desalination in seaweed is easily performed in a short time. According to the present invention, as described above, two sheets of glass
The three tanks separated by the fiber membrane sheets 1 and 2 are
And a central water tank 4 and a negative water tank 5.
A positive electrode 6 made of a carbon alloy is arranged, and a gold
Or a negative electrode 7 made of platinum, and the central water tank 4 is desalted.
Seagrass 8 which is a target is hung by hook 9
And then inject fresh water from the central water tank 4
Fill the positive electrode water tank 3 and the negative electrode water tank 5 through the membrane sheets 1 and 2.
Full, connect DC current to the positive and negative electrodes 6, 7 and let current flow
And seaweeds 8 suspended by hooks 9 in the central aquarium 4
Salt quickly dissolves in water, turning into Na + and Cl - ions
It is ionized, and moved to the negative electrode water tank 5 and the positive electrode water tank 3, respectively.
Ion exchange is performed between the negative electrode 7 and the positive electrode 6, respectively, and NaO
H and HCl are generated.
Of the negative water tank 5 and the positive water tank 3 by the flow of fresh water injected into the tank
The salt in the seaweed is extruded from the mouth 10 and 11
Due to the difference, only salt first electrolyzes and desalination in seaweed
Is a desalination method for seaweeds that can be easily performed in a short time, so that only salt can be selectively extracted without losing nutrients such as calcium, iron, and iodine that are important as foods for kelp. .
