[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water reformer, and more specifically, it allows tap water or well water to pass through two layers consisting of an anion exchange resin layer and a water-insoluble material layer having a large surface area. Drinking, cooking, food manufacturing, plant cultivation,
The present invention relates to a water reformer capable of providing modified water suitable for beauty and the like.

2. Description of the Related Art Conventionally, it has a pleasant mouthfeel similar to groundwater and hot spring water that springs between rocks and sand for a long period of time.
As a method of converting water having high penetrating power, that is, water having a small line width of water, an electrolysis method, an ultrasonic method, a magnetizing method, a far infrared method and the like are known. However, the electrolysis method has a problem that it becomes alkaline water and acidic water and is costly, and the ultrasonic method, the magnetizing method, and the far-infrared method require a long time to change water, and continuous There is a problem that it can not be done.

By the way, the cathode water (alkaline water) of the electrolyzed ion water generator, which was approved as a medical device (60B No. 779) by the Ministry of Health and Welfare in 1965, is
It is said to be effective for drinking, abnormal fermentation in the gastrointestinal tract, chronic diarrhea, indigestion, antacid, and excess gastric acid. (In addition, anodic water is used for beauty as a weakly acidic astringent). This is because the water is reformed into water with high penetrating power. Regarding this, Mr. Kazuhiro Matsushita of JEOL Ltd. makes one hypothesis. The hypothesis is that by measuring the linewidth of water using a nuclear magnetic resonance apparatus (NMR),
It is a theory that the state of clusters of water molecules can be elucidated. In other words, the line width of water gives a signal corresponding to the size of the lump of water molecules, and is a numerical value of this. The smaller the value, the smaller the lump of molecules. For example, the line width of electrolyzed water is 55 to 80 Hertz, tap water is 90 to 150 Hertz, and well water is 85 to 12 Hertz.
0 hertz and distilled water are 110 to 130 hertz. In this way, the line width value of water is proportional to the penetrating power of water, and as the line width of water becomes smaller, the penetrating power of water becomes larger, and when this water is drunk, it tastes good and is delicious. It can be expected to have effects such as fast absorption in the stomach, rapid excretion, and clean stool (according to data of electrolyzed water).

When used for food, the flavor of food and food is improved, and the freshness of food is long-lasting.When used for plant cultivation, plant growth is promoted, yield is increased, and fruit and vegetable flavors are increased. It increases energy consumption, increases sugar content, increases density, and has the effect of smoothing the skin when used as a bath or shower or face wash, and does not harm human bodies or plants, and uses energy. It is an object of the present invention to provide a water reformer which is effective for a long period of time and has a low cost.

The present invention is directed to an anion exchange resin layer and a water insoluble material layer having a large surface area (hereinafter referred to as
(Sometimes referred to simply as a “material layer”) and a water conditioner. Hereinafter, the anion exchange resin layer and the material layer constituting the water rectifier of the present invention will be described separately.

Anion exchange resin layer The anion exchange resin used in the anion exchange resin layer is
Nitrite-based nitrogen (N, a nitrogen compound existing in water)
O ₂ -N) and nitrate nitrogen (NO ₃ ^- -N) removed, small lumps of which is the object of high penetrating power (water molecules break water dispenser of the present invention) to Aratamesui water It is used as a pretreatment of. Therefore, in the water improver of the present invention, it is necessary to set this anion exchange resin layer on the water supply side and arrange the material layer on the downstream side of the water.

The anion exchange resin is a Cl ^- ion,
A resin that exchanges anions such as NO ₃ ⁻ ions or SO ₄ ²⁻ ions. Depending on the strength of its basicity, there are two types of resins, strong basic anion exchange resins and weak basic anion exchange resins.
There are types. Here, the strongly basic anion exchange resin has a quaternary ammonium group as an exchange group, and has NaOH or K
At the same time, strong alkali such as OH is dissociated to show strong basicity, and mineral acids and neutral salts are decomposed and ion-exchanged. On the other hand, the weakly basic anion exchange resin has primary to tertiary amino groups as exchange groups and is weakly basic, so that it does not dissociate in an alkaline aqueous solution and has no ion exchange ability. Therefore, mineral acids such as HCl and H ₂ SO ₄ and weakly basic salts such as NH ₄ Cl can be ion-exchanged, but weak acids and neutral salts cannot be ion-exchanged. Therefore, the anion exchange resin used in the present invention is preferably a strongly basic anion exchange resin. In addition,
When the anion exchange resin becomes saturated, for example, N
It can be easily regenerated by washing with an aOH aqueous solution.

The anion exchange capacity of the anion exchange resin is

1, weakly basic anion exchange resin 1.2-2.5 meq
/ Ml, the reaction rate and reaction rate were 1 in 2 seconds.
0-15%, 5-30 seconds 20-30%, 10 seconds 35-50
%, It is about 65 to 85% in 20 seconds. The amount of total anions in water is 0.5 to 4.0 mg of nitrate nitrogen and nitrite nitrogen, 3.0 to 30 mg of chloride ion, phosphate ion, etc. in 1 liter of water in ordinary tap water. Anion of 0.01-0.2 mg, total 3.51-4.2 m
It is about g. By the way, in order to reduce the lump of water by passing through the material layer and to obtain water with high osmotic power, the pretreatment with this anion-exchange resin layer, which is the pretreatment step, is used to remove the nitrate chip in water. It is preferable that the content of nitrogen and nitrite nitrogen is at least 0.9 mg or less, preferably 0.5 mg or less, per liter of water.

Therefore, the necessary amount of the anion exchange resin for the water reformer of the present invention is, considering the practical treatment time of water,
By contacting water for at least 2 to 30 seconds, preferably 5 to 20 seconds, the content of nitrate nitrogen and nitrite nitrogen in water is at least 0.9 per 1 liter of water.

[Table 6] Note) The water reformer F-1-2 is a FB type (see FIG. 8), and the anion-exchange resin layer and the material layer are arranged in reverse, so that a material layer with a large surface area of water is used. It can be seen that even after removing the nitrate nitrogen and the nitrite nitrogen after passing, the water does not have a large dialysis power and the line width is large.

[0048]

[Table 7] Note) The water reformer F-2-0 is an F-A2 type (see FIG. 7), and since the activated carbon layer and the anion exchange resin layer are sequentially arranged, Similarly, it can be seen that even after removing the nitrate nitrogen and nitrite nitrogen after the water has passed through the activated carbon layer having a large surface area, the water does not have large dialysis power and the line width is small. .

[0049]

[Table 8] Note) The water reformer F-2-0 is an F-A2 type (see FIG. 7), and since the activated carbon layer and the anion exchange resin layer are sequentially arranged, the activated carbon layer having a large surface area for water is used. After passing through, even if the nitrate nitrogen and nitrite nitrogen are removed,
It can be seen that the line width of water is large when compared with the water reformers A-1-1 and D-3-1.
