Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to drinking water in which the dissolved oxygen concentration of water before treatment is lowered, a method for producing the same, and an apparatus for the same.

[0002]

2. Description of the Related Art Generally, the concentration of dissolved oxygen contained in tap water and the like is approximately constant, and is about 8 p.pm. This dissolved oxygen is oxygen in a molecular state, maintains an equilibrium state with oxygen in the air in vapor pressure, and is constantly maintained at a constant value. In order to control the dissolved oxygen concentration, deoxidation is conventionally performed with a deoxidizer such as iron ions. It is also known to use an oxygen-selective permeable membrane capable of specifically selecting oxygen.

[0003]

The control of dissolved oxygen by the addition of a deoxidizing agent is not suitable for drinking water due to the problem of the solubility of the agent itself and the side effects of the agent. Further, when dissolved oxygen is controlled using an oxygen-selective permeable membrane, it is rarely used except in special cases due to difficulty in use and economic factors. It is an object of the present invention to solve such problems and to provide a better drinking water, a method for producing the same, and a device thereof easily and economically.

[0004]

According to the present invention, the concentration of dissolved oxygen is lowered by imparting far infrared rays from a fired body having far infrared radiation characteristics and magnetic lines of force from a magnetic material to water before treatment. . The present invention changes the external electronic state of a dissolved oxygen molecule by the action of at least one of a magnetic substance having a magnetic strength of 500 gauss or more and far infrared radiation, that is, a line of magnetic force or a far infrared ray so that the oxygen molecule has an ionization tendency. As shown in the figure, the molecular oxygen is reduced by gently binding with water molecules, and the dissolved oxygen concentration is reduced compared to the water before treatment (especially drinking water with a dissolved oxygen concentration of 6 p.pm or less. ) Can be obtained.

[0005]

EXAMPLE The produced water according to the present invention is capable of obtaining produced water in which the dissolved oxygen concentration is lowered by at least one of the far infrared rays by the fired ceramics having far infrared radiation characteristics and the magnetic lines of force by the magnetic material. The main raw material of the fired body is preferably SiO ₂ and Al ₂ O _3, and the magnetic strength of the magnetic field is preferably about 500 gauss or more. It is preferable that the drinking water produced by the present invention is in direct contact with the water before treatment and the magnetic material having a magnetic field is not in direct contact with water, but the magnetic force acts directly on the water. However, the water passing through these steps has a reduced dissolved oxygen concentration on the output side as compared to the input side due to the action of far-infrared radiation and / or the action of magnetic force.

Example 1 A case is shown in which drinking water is produced using a fired body (ceramics) having far infrared radiation characteristics and a magnetic body (magnet) having a magnetic field. As ceramics, SiO ₂ (45.8%), Al
₂ O ₃ (43.5%), Fe ₂ O ₃ (4.5%), TlO ₂ (2%), K ₂ O
(1.6%), Na ₂ O (1.4%), CaO (0.7), MgO (0.3%), which was formed into a ball shape. This ceramic ball has a far infrared ray characteristic as shown in FIG.

The ceramic ball and magnet are provided in a tank having an inflow / outflow port, and tap water is supplied from the inflow port at a rate of 10 min / min.
A liter of water was flowed in to bring the tap water into direct contact with the ceramic ball, and indirectly through the magnetic poles between the N and S poles of the magnet. Thus, the dissolved oxygen concentration of the drinking water flowing out from the outlet was measured. The results are shown in Table 1. The magnets have magnetic field strengths of 200, 400, 500, 90.
Measurements were made in each case using those of 0, 1300 and 1600 gauss.

[0008]

[Table 1] When the graph of FIG. 2 is created based on this Table 1, the dissolved oxygen concentration of drinking water is decreasing, as is clear from this graph. It should be noted that the dissolved oxygen concentration is remarkably exhibited at about 500 gauss or more, and is 6 p.pm or less.

Example 2 The above tap water was flowed in from the input side at 10 liters per minute, and only a magnetic line of force was applied to the water using a magnet, and the dissolved oxygen concentration of the drinking water was measured. The magnetic field strength is 20 as in the first embodiment.
It was performed at 0,400,500,900,1300,1600 gauss. The results are shown in Table 2 and shown in a graph as shown in FIG.

[0010]

[Table 2] As is clear from the graph of FIG. 3, the dissolved oxygen concentration of tap water decreased. Also in this case, the difference between the dissolved oxygen concentration on the input side and the input side was remarkable at about 500 gauss or more.

Example 3 The above tap water was flowed in from the input side at a rate of 10 liters per minute, the water was brought into contact with (passed through) the ceramic ball to give only far infrared rays, and the dissolved oxygen concentration of the drinking water was adjusted. It was measured.
The contact time between the water and the ceramic ball was set to 30, 60, 90, 120, and 150 minutes for passage. The results are shown in Table 3 and FIG.

[0012]

[Table 3] From this result, it was found that the concentration of dissolved oxygen in the tap water was reduced even when only the far infrared rays due to the ceramics were used.

An apparatus for reducing the dissolved oxygen concentration of the tap water is shown in FIGS. The illustrated one accommodates a plurality of ceramic balls (4) in a stacked state in a lower tank (3) supported by legs (2) in the form of a vertical tank (1), and also an upper tank ( A flowing water pipe (6) fixed by a support plate (17) is provided in the inside of 5), and a magnet (7) is mounted around the flowing water pipe.

The ceramic ball (4) is usually 13 to 1
Use a hole having a diameter of about 5 mm, and use these holes with a large number of holes (9) such as a punching board (8)
mm diameter is used, but other diameters may be used). Cleaning, replacement, inspection, etc. of the ceramic ball are performed from the inspection port (10).
Instead of the ceramic ball, a ceramic block body (12) having a water flow hole (11) as shown in FIG. 18 or another shape may be used.

The magnet provided on the outer periphery of the water flow pipe (6) is formed in a plate shape as shown in the figure, and the magnet is laminated in three stages or another number of stages, and the outer periphery thereof is a band (13).
However, the magnet may be formed in a cylindrical shape so as to cover the outer circumference of the running water pipe, or the magnet may be fixed with a contact agent. The magnetic poles of the stacked magnets are shown in FIG.
It may be arranged in an arrangement as shown in FIG. 10 or another arrangement, but in any case, it is formed so that the magnetic force lines are given to the tap water flowing through the water pipe.

The flowing water pipes (6) can be formed in an appropriate number, and can be provided, for example, as shown in FIGS.

Tap water (water before treatment, source water) flowing in from the inlet (14) directly contacts the ceramic ball (4) through the hole (9) of the punching board (8). Far infrared rays are given from the ball here and then pass through the flowing water pipe (6). At that time, magnetic lines of force are given from a magnet (7) provided on the outer circumference of the flowing water pipe, and from the outlet (15). leak. When the water is brought into contact with the ceramic ball, if the ceramic ball is accommodated between the upper and lower punching boards in a state of about 80%, the ceramic ball floats by hydraulic pressure and the ceramic ball is suspended. The contact area with the solder is increased. An intake / exhaust port (16) is appropriately provided in the tank.

In the illustrated example, tap water is introduced from the lower part, but it may be introduced from the upper part depending on the mounting condition of the tank, or the tank may be laid sideways. In addition, when the tap water was first applied to the magnetic field lines, better results were obtained than when the far infrared rays were first applied.

The above-mentioned magnet (magnetic material) is designed so as not to come into direct contact with water. However, if there is no partial destruction of the magnet, it may be brought into direct contact, or a coating may be formed on the surface of the magnet. You may make it contact water directly.

The above device can be formed of a corrosion resistant material such as synthetic resin or stainless steel.
