Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fluid treatment apparatus using a vector potential field generated by a magnet.

[0002]

2. Description of the Related Art Conventionally, as a treatment of a fluid by magnetism, for example, a treatment of forming magnetic wave water, a magnet m is arranged around a flow pipe P as shown in a schematic sectional view of FIG. There is a configuration in which the same pole (N pole in the figure) is disposed toward the flow pipe P to allow water flowing in the flow pipe P to pass through a magnetic field generated by the magnet m.

[0003] Since water is a polar molecule, it undergoes a clustering effect by passing through a modulated magnetic field, while free electrons in impurities dissolved in water or ionized substances are converted to water. It is known that an electromotive force according to Faraday's law of electromagnetic induction works, and a small current is generated, thereby producing an effect such as denaturation of red rust and enabling water reforming.

[0004]

However, in the conventional magnetic wave water treatment technology, since the same poles are opposed to each other with the flow path interposed therebetween, a strong magnetic field can be generated. Since the direction of the action of the magnetic field applied to the water flowing through the water varies depending on the location, the generation efficiency of the microcurrent generated by the magnetic field is low, and the water reforming efficiency is low.

[0005] Further, by the magnetic field lines of the generated magnetic field,
Magnetic material such as iron powder dissolved in the water in the flow channel, especially when groundwater is used for pumping, iron sand etc. is sucked and adsorbed on the inner surface of the flow channel, the pipe diameter is narrowed,
There was a problem that the amount of flowing water was reduced.

[0006]

In order to solve the above-mentioned problems, according to the present invention, two sets of even-numbered magnets are provided, each having a different polarity with respect to a fluid flow path. It is an object of the present invention to provide a fluid processing apparatus in which fluids flowing in a flow path are arranged to face each other and are orthogonal to magnetic lines of force generated by a magnet.

According to the second aspect of the present invention, a cylindrical processing main body is provided in a part of the flow path through which the fluid flows, and the processing body is arc-shaped. A magnet having an N pole, a magnet having an N pole on the inside, and a magnet having an S pole on the outside are disposed in the processing body with the inside facing each other, and the magnet is covered with a magnet protection cover, To provide a fluid processing device in which the fluid flowing through the fluid is orthogonal to the magnetic lines of force generated by the magnet.

Further, according to the present invention, a magnet arrangement hole in which a magnet can be arranged is formed, the magnet is arranged in the magnet arrangement hole, and the magnet is fixed with a magnet fixing screw. A fluid treatment device surrounded by two symmetrical magnet holders across a flow path tube through which a fluid flows, wherein one magnet holder has an even number of magnet arrangement holes formed therein, In the magnet arrangement hole, magnets are arranged with the N pole side facing the flow tube side,
In the remaining half of the magnet arrangement holes, a fluid treatment apparatus in which a magnet is arranged with the S pole side facing the flow path pipe side and a buffer plate made of a magnetic material is interposed between the magnet holder and the flow path pipe Is to be provided.

Further, in the fluid processing apparatus, the magnet mounting holes of the opposed magnet holders are located at positions where the magnet mounting holes formed in the two magnet holders face each other across the flow path pipe. The magnets arranged in the respective magnet arrangement holes facing each other are also characterized in that they are arranged with different poles facing each other.

[0010]

DETAILED DESCRIPTION OF THE INVENTION The present invention is directed to the modification of fluids, in particular, to the vector potential field generated by a magnet,
This is a fluid processing device that atomizes water clusters.

[0011] When generating conventionally known magnetic wave water, as described in the related art, water passes through a magnetic field generated by a magnet, so that water clusters become finer, and It is considered that an electromotive force is generated according to Faraday's law of electromagnetic induction, and that water is reformed.

However, it is not the magnetic field (in this case, the magnetic field is described as “B”, but the vector quantity) that contributes to the water cluster micronization, but “B = ro”.
tA ”(where“ A ”indicates a vector potential,
(A is also a vector quantity).

In other words, microscopically, water, which is a polar molecule, passes through the vector potential field generated by the magnet, thereby interacting with the vector potential field, and water clusters are made finer. -ing

When the water cluster is formed into fine particles, the solubility of impurities or physical properties such as permeability are improved, so that the water cluster feels delicious when taken and the skin becomes smooth when used for bathing. It can improve the off-flavor and off-taste of tap water.

Therefore, when water clusters in a fluid are atomized, essentially a modulated vector potential field only needs to be present. In the present invention, a more strongly modulated vector potential field is obtained. Use powerful magnets.

The higher the percentage of the modulation of the vector potential field, the smaller and finer the water clusters are, and the better the physical properties can be.

According to the present invention, in order to form a strong vector potential field, an even number of magnets are set in pairs, and the magnets are arranged so that different poles are opposed to each other so as to sandwich the flow path through which the fluid flows. Then, the fluid flowing through the flow path is caused by the vector potential field generated by the magnet,
It is configured to receive the water cluster micronization action.

In particular, since the magnetic field generated by the magnet and the fluid flowing through the flow path are configured to be orthogonal to each other, the law of Faraday's electromagnetic induction by the magnetic field can be used most efficiently, and free impurities in water dissolved in water can be used. It is configured to perform the most efficient modification of electrons or ionized substances.

However, when a magnetic field is applied to the fluid flowing through the flow path by the fluid processing apparatus, magnetic substances such as iron powder and iron sand mixed in the fluid are attracted and adsorbed on the flow path wall. In order to reduce the diameter of the flow path, the fluid processing device is removably interposed in a part of the flow path through which the fluid flows. The processing unit is removed to make it easier to remove the adsorbed magnetic material.

As another method, a plate made of a magnetic material is interposed between a magnet and a flow path so that the plate functions as a damping plate, and the flow path is brought into a zero magnetic field state. The magnetic material such as iron powder and iron sand is prevented from adsorbing to the inner surface of the flow path.

Although the inside of the flow path is in a zero magnetic field state, there is a vector potential field, and the water cluster can be made finer by the vector potential field, and the water quality can be reformed.
