Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a water treatment filter device and a water treatment device that include a water treatment filter device and treat water by passing through the filter. More specifically, the present invention relates to a water treatment filter device and a water treatment device using the above-described filter to neutralize water such as tap water, well water, hollow fiber membrane permeate, or reverse osmosis membrane permeate to make it slightly alkaline.
[0002]
[Prior art]
In general, it is said that water suitable for the body is weak alkaline water having a pH of about 8 to about 8.5. As a method of neutralizing water to increase the PH value, a method using calcium can be considered. Then, the present inventor tried a method of manufacturing a filter using a calcium filter medium and treating water by passing the filter through the filter. According to this method, the water comes into contact with and reacts with the filter medium, and the calcium component is eluted into the water while passing through the filter medium. Therefore, the PH value of the water increases, and the water can be converted to alkaline water.
[0003]
However, according to the above-mentioned method, since all the water passes through the calcium filter medium, the amount of the calcium component eluted in the water, and hence the content of the calcium component in the water, becomes too large, and thus the PH value becomes too high. As a result of an experiment performed using water such as tap water, it was found that the PH value was about 12 to about 14.
If the PH value is too high, it does not have good results on human health. Suitable water for the body ranges from less than about pH 8 to about 8.5 as described above.
[0004]
In addition, since the above-described method allows all water to pass through the calcium filter medium, the amount of the calcium component eluted is large at the beginning of use as described above, and thereafter the amount of the calcium component eluted gradually decreases with time. As a result, the PH value also gradually decreases, and it becomes impossible to neutralize to weak alkaline.
[0005]
As described above, the above method has a problem that the PH value of water passing through the filter changes and cannot be kept constant, and the water cannot be stably alkalized for a long period of time. are doing.
[0006]
[Problems to be solved by the invention]

[0014]
The divalent iron (III) iron salt is a recently developed active substance, and the active substance is an inorganic salt such as iron hydrochloride, sulfate, nitrate, etc., which has an intermediate property between ferrous iron and ferric iron, and formic acid. Organic salts such as salts, acetates, and poropionates. For example, ferric chloride is added to an aqueous solution of a strong alkali such as sodium hydroxide, calcium hydroxide, potassium hydroxide, and lithium hydroxide to convert the valence. Is obtained as a transition form in the case of causing, and can be industrially produced at present.
[0015]
It has been found that the above-mentioned active substance of divalent and trivalent iron salt has the following effects when it comes into contact with water. That is, a very small amount of the active substance (concentration: 2 × 10^-12By mixing (mol = 1/20 trillion), a 1/20 trillion% aqueous solution of this substance (hereinafter, this aqueous solution is referred to as “pie water” for convenience) has been found to have the following properties.
[0016]
(Structural change of water molecule) ... Normally, the water molecule of water has positive and negative polarities because the centers of gravity of hydrogen and oxygen do not change. Therefore, since water molecules are combined in a cage shape by hydrogen bonding, hydrocarbons, methane, gas, and the like are dissolved in the cage. On the other hand, in piwater, the spin structure of water molecules and water molecules is changed from a polar molecule to a nonpolar molecule by electron spin, that is, the center of gravity of H (hydrogen) and O (oxygen) is increased, and bipolarity is eliminated. . In other words, the water molecule itself does not have plus and minus, and as a result, hydrocarbons and the like do not dissolve like ordinary water.
[0017]
(Deionization reaction)… In general, metals and metal salts undergo ion dissociation in water, causing substance changes mainly due to ion reactions. However, since there is no plus or minus in pi water, metal ions are desorbed and non-dissociated. Form an ion reaction system.
[0018]
(Inhibition of pathogenic bacteria) ... Bacteria and other germs are single-celled microorganisms that have a negative charge. They usually inhabit the ion reaction system of water, but suppress the ionic reaction in pie water, change the equilibrium state of the germs, and of course multiply. Create an environment where it cannot live.
[0019]
As described above, it has been experimentally proved that the substance is activated by changing the structure of the water molecule. As described above, the second and third inventions each include the water activation filter, and are configured to allow water to pass through the second water treatment agent layer. Therefore, in the second and third inventions, water passes through the layer and contacts and reacts with the active substance of the ceramic solid to become water containing a ferrous (III) iron salt.

In addition, the said manufacturing method showed an example, and it is not limited to this.
[0021]
In the second invention, as the divalent iron (III) salt, a magnetic iron (III) salt may be employed instead of the compound represented by the above formula. The magnetized divalent and trivalent iron salt is an active substance having both characteristics by electromagnetic treatment and characteristics by chemical treatment at the same time, and is obtained by, for example, chemically treating magnetite.
[0022]
The magnetically active substance of divalent and trivalent iron salt has the following properties upon contact with water. That is, a very small amount of the active substance (concentration: 2 × 10^-12By mixing this substance with 1/20 trillion), the 1/20 trillion% aqueous solution of this substance has, in addition to the above-mentioned properties of the pie water, the same properties as the electromagnetically-treated active water. Since it is dissolved in and coexists with water, it acts stronger and more effectively on water than activated water applied with an external magnetic field.
[0023]
In the present invention, as the ferrous salt having magnetism, for example, after dissolving magnetite in concentrated hydrochloric acid, the solution is neutralized, and the neutralized solution is concentrated and crystallized. Is added to a solution in which magnetite is half-dissolved in concentrated hydrochloric acid.

Therefore, the water is neutralized (adjusts the PH value) by the split flow water and becomes weakly alkaline water.
[0052]
In addition, the filter device of the first embodiment is generally considered to be used with the water outlet 20 side positioned at an upper position and arranged in a vertical posture, but in a horizontal or other arbitrary posture. Needless to say, it can be configured to be arranged and used. The arrangement configuration of the above-described posture is the same in each embodiment described later.

In the water treatment filter device of the present invention, in the configuration shown in the first embodiment, the partitioning chamber 18 is omitted, and the housing chamber 12 and the water merging chamber 13 are directly connected by the communication portion 33 (the hole or the groove described above). It is also possible to adopt a configuration for communicating. When this configuration is adopted, the second partition plate 23 and the communication hole 34 become unnecessary. According to this configuration, the water passing through the layer 15 merges with the water flowing out from the main flow pipe 14 in the water merging chamber 13. The above-mentioned modified example of the water treatment filter 1 is the same in the embodiment described later.

For example, the raw material of the ceramic base material 101a is kneaded and formed into a desired size and shape. About 100,000 to about 1 / 10,000,000 in water (preferably distilled water, etc.) used in the process, that is, about 100,000 to about 1 / 10,000,000 in the distilled water or the like. The purpose can be achieved by using the aqueous solution as water for kneading the clay material. However, it is not limited to the above range of%.
[0061]
Next, an example of a specific method for producing the ceramic solid 101 will be described.
First, the active substance of the bivalent and trivalent iron salt represented by the above formula can be produced, for example, by the following method. That is, 1.0 mg of ferric chloride is put into 100 ml of 0.5N aqueous sodium hydroxide solution, stirred and dissolved, and left standing for 24 hours. After removing the insoluble substance generated in the solution, the solution is neutralized with hydrochloric acid, concentrated under reduced pressure, and dried and crystallized in a desiccator. The obtained crystals were re-dissolved by adding 50 ml of an 80% by weight aqueous solution of isopropyl alcohol, concentrated under reduced pressure to remove the solvent, dried, and the re-dissolution, concentration and drying were repeated several times to obtain 0.25 mg of crystals ( An active substance of iron (III) salt was obtained. The crystals are dissolved in about 11 (1 liter) of water (such as distilled water) to obtain a stock solution.
[0062]
Next, the solid material 101 can be produced, for example, by the following method. That is, as shown in FIG. 6, about 70% by weight of clay (powder) is used as a main raw material of the ceramic base material 101a, and about 10% by weight of zeolite (powder) is used as an additive (material). 10% by weight and about 10% by weight of sawdust are blended. Then, the above-mentioned raw materials, that is, the clay 102, the zeolite 103, the alumina 104, and the sawdust 105 are put into an appropriate container 106 as shown in FIG. 6A, and the undiluted solution of the divalent trivalent iron salt is added thereto with distilled water or the like. An appropriate amount of a diluent (aqueous solution) 107 diluted about 1000 to about 2000 times with water is added, uniformly stirred and kneaded, and formed into a desired size (for example, a ball having a diameter of about 10 mm) (FIG. 6B). Then, the molded article 101b is fired at a suitable temperature (for example, about 800 ° C. to about 1100 ° C.) for a suitable time (for example, about 10 hours to about 30 hours). As a result, the molded article 101b is fired and solidified into a ceramic shape, and the divalent and trivalent iron salts are simultaneously sintered and uniformly supported on the ceramic base 101a, and the sawdust is burned to burn the ceramic base 101a. Are formed with a myriad of fine holes (chambers) 108 as a whole, and a ceramic solid 101 is produced (see FIG. 6C).
[0063]
When the ceramic solid 101 manufactured as described above is put into water, the water penetrates into the base material 101a through the holes (chambers) 108 of the ceramic base material 101a and contacts and reacts with the substance. It becomes water containing a divalent and trivalent iron salt represented by the formula. In addition, since the substance is integrally sintered and supported on the ceramic substrate 101a, it does not elute into water at one time, but stays in the substrate and acts stably continuously for a long time (effectively). The duration of action is about 1-2 years).
[0064]
The water activation filter 20 of the water treatment filter device according to the second embodiment includes a second water treatment agent layer 44 formed by filling a desired number of the ceramic solids 101 in a housing 41. With this configuration, water such as tap water introduced from the water inlet 42 of the housing 41 passes through the filter member 45, the water treatment agent layer 44, and the filter member 46 as shown by arrows in FIG. It flows out of 43. Then, while passing through the layer 44, the water comes into contact with and reacts with the ceramic solid substance 101, and becomes water containing the divalent iron (III) salt represented by the above formula.
[0065]
The water flowing out of the water outlet 43 of the water activation filter 20 is supplied to the pipe P₁The water is introduced from the water inlet 19 to the water treatment filter 1 through the water inlet, neutralized (pH value is adjusted) in the same manner as described above, and flows out from the water outlet 20. This water becomes weakly alkaline suitable for the body similarly to the first embodiment, and in addition, becomes water having the above-described properties due to the action of the divalent and trivalent iron salts.
[0066]
In Embodiment 2, as the divalent iron (III) salt, a magnetic iron (III) salt can be employed instead of the compound represented by the above formula. As described above, the ferrous salt having magnetism is an active substance having both the property by the electromagnetic treatment and the property by the chemical treatment at the same time. This active substance can be produced, for example, by the following method.
[0067]
That is, 0.1 g of magnetite is placed in 10 ml of concentrated hydrochloric acid, dissolved by stirring, and allowed to stand for 24 hours. To this solution, 25 ml of a 2N aqueous sodium hydroxide solution is added and left standing for 24 hours to neutralize. The solution is concentrated under reduced pressure to precipitate crystals, and the crystals are dried in an air dryer. The crystals are washed in 10 ml of ethyl alcohol. This washing operation is repeated several times to purify the crystal to obtain an active substance (crystal). The yield at this time was 0.88 g. Next, 5 g of magnetite is put in 10 ml of concentrated hydrochloric acid, and the mixture is half-dissolved by stirring. Then, 0.1 g of the active substance crystal obtained in the above step is added, and the mixture is stirred well and allowed to stand for 24 hours. The supernatant is separated from the insoluble magnetite by a decantation method to obtain an active substance solution (a magnetic substance-containing active substance solution of a ferric (III) salt).
[0068]
Then, using the active substance solution obtained as described above, a treatment is carried out in the same manner as in the case of the ceramic solid 101 to produce a ceramic solid carrying magnetic divalent and trivalent iron salts. In the production of the ceramic solid, the amount of the active substance solution mixed into the raw material of the substrate 101a is the same as that of the ceramic solid 101. In this case, the solution is dissolved in water (distilled water or the like) to obtain a stock solution. As a result, the treated water becomes weakly alkaline suitable for the body as in the first embodiment, and becomes water having the above-mentioned properties due to the action of the ferrous salt of magnetism.
