[0003]

Since the conventional magnetic deoxidizing method is constituted as described above, there are the following problems. That is, when the above-mentioned conventional method is adopted, the configuration of the apparatus itself becomes large and expensive, and the energy required for the processing becomes enormous,

The present invention has been made to solve the above problems, and in particular, a magnetic field for achieving deoxidation by utilizing the zero position of the magnetic field formed by a strong magnetic field gradient in the air or water. It is an object to provide a deoxidizing method and apparatus.

[0005]

The magnetic deoxidation method according to the present invention is a method for separating paramagnetic oxygen in the air or water by using the zero position of the magnetic field generated by a strong magnetic field gradient.

More specifically, the strong magnetic field gradient is generated by magnetic field lines of a magnetic field coil or a permanent magnet.

The magnetic deoxidizing apparatus according to the present invention comprises a plurality of strong magnetic field generators arranged to face each other to generate a strong magnetic field, and a magnetic field formed at a substantially central portion between each strong magnetic field generated from the strong magnetic field generators. And the magnetic field zero position where the strength of becomes zero,
The oxygen density at the position where the magnetic field is zero is kept low.

More specifically, each of the strong magnetic field generators is provided in a container and an oxygen discharge hole is provided in the container.

More specifically, each of the strong magnetic field generators is provided in a water container, and the water container is provided with a water supply pipe, a drainage pipe, and an oxygen-free water take-out pipe. The tip of the take-out pipe is provided near the zero magnetic field position.

More specifically, the strong magnetic field generator comprises a strong magnetic field coil.

More specifically, the strong magnetic field generator is a permanent magnet.

[0012]

In the magnetic deoxidizing method and apparatus according to the present invention, a plurality of strong magnetic field coils or permanent magnets are provided so as to face each other, thereby generating a magnetic field zero position where the magnetic field strength becomes zero. A strong magnetic field gradient is generated around it. Therefore, the paramagnetic oxygen existing in the air or water is expelled from the magnetic field zero position, so that the oxygen-free region can appear at the magnetic field zero position. Therefore, in the air, an oxygen-deficient region can be obtained, and, for example, oxidation of a metal or the like that is easily oxidized can be prevented. Also, in the case of underwater, by positioning the tip of the oxygen-free water extraction pipe at this magnetic field zero position,
It is possible to take out water in a relatively oxygen-free state, and to obtain water with little oxidation and change in taste.

FIG. 4 is a configuration diagram showing an embodiment of FIG. 4, and FIG. 4 is a configuration diagram showing another embodiment using a permanent magnet.

In FIG. 1, reference numerals 1 and 2 denote a first strong magnetic field coil and a second strong magnetic field coil, which are annular strong magnetic field generators provided facing each other and having the same standard. The strong first, second, third, and fourth magnetic force lines 3, 4, 5, and 6 indicated by solid arrows are obtained by causing the currents in the coils 1 and 2 to flow in opposite directions.

The magnetic lines of force 3, 4, 5, 6 flow from the center of the space 7 between the coils 1, 2 so as to press each other on a plane of symmetry, and the magnetic lines of force 3, 4 are located at the center of the space 7. 5,
The strong magnetic field gradient of 6 forms a zero magnetic field position 8 where the magnetic field strength is zero (oxygen density is kept low).

Therefore, if a metal or the like that is easily oxidized is placed at the zero position 8 of the magnetic field, paramagnetic oxygen is separated by a strong magnetic field other than the zero position 8 of the magnetic field. Is extremely diluted, and the oxidation of metal or the like can be prevented.

The atmosphere in the configuration of FIG. 1 can be applied to both the case of being in the air and the case of being in the water.

The structure shown in FIG. 2 is a structure in which the structure shown in FIG. 1 is applied in the air, and a metal member 11 is arranged at the magnetic field zero position 8 using a container 9 having an oxygen discharge hole 10. The oxygen density is relatively high near the container wall 9a of the container 9.

Therefore, the air having the high oxygen density is exhausted to the outside through the oxygen exhaust hole 10, the oxygen density at the magnetic field zero position 8 where the metal member 11 is located is kept low, and the metal member 11 is kept. Oxidation is prevented. The magnetic field in the vicinity of the container wall 9a in this case is about 2 tesla.

When water is supplied from the water, the oxygen in the water is separated by the strong magnetic field, and the water containing excess oxygen is discharged from the drain pipe 32 to the outside.

Further, since the oxygen density of water at the magnetic field zero position 8 is extremely low, water with a low oxygen density is taken out from this oxygen-free water take-out pipe 33.

Further, since the water taken out from the oxygen-free water take-out pipe 33 has an extremely low oxygen density, microorganisms do not grow and organic substances are not oxidized. Therefore, water whose taste does not change must be supplied. You can In addition, near the inner wall 30a of the water container 30, it is preferable that the strength of the magnetic field is 2 Tesla or more.
