In the figure, reference numeral 100 denotes a three-phase AC power supply, 2a to 2c denote output terminals of a three-phase AC power supply, and 2d denotes a three-phase AC power supply. Neutral terminals 1a to 1c of the power supply are arranged in the water tank 30, and wiring 3a is connected to each of the three-phase output terminals 2a to 2c.
Electrodes such as three carbon electrodes connected by 3c
Reference numeral 1d denotes a neutral electrode 90 which is connected to the neutral terminal 2d by a ground wire 3d, and comprises a carbon electrode or the like arranged opposite to the three carbon electrodes 1a to 1c.
Is a plurality of arcs between the electrodes 1a to 1c and the object 800, the electrodes 1a to 1c and the neutral electrode 1d, and the electrodes 1a to 1c. Reference numeral 20 denotes water contained in a container 30 composed of a water tank.

Reference numeral 700 denotes the three carbon electrodes 1 described above.
A storage member formed to surround the arc formed by a to 1c and storing oxygen, hydrogen, and the like generated by Mizuno decomposition.

Next, the operation will be described. In this embodiment, each of the three electrodes 1a to 1c in each of the three electrodes 1a to 1c in the water 20 placed in the water tank 30 has a three-phase AC shown in FIG.
By applying C, the three electrodes 1a to 1
c and the workpiece 800, a plurality of arcs, ie, multi-arcs, are generated between the three electrodes 1a to 1c and the neutral electrode 1d and between the three electrodes 1a to 1c. This multi-arc is very powerful, its temperature reaches a very high temperature, a strong flame like lightning emerges in the water, and due to the heat generated by this, the water is locally heated and boiled, and the water vapor and It forms bubbles by decomposing into hydrogen and oxygen. In addition, when this multi-arc is generated, far infrared rays, ultrasonic waves, light, blue light of the arc, and 5
A shock wave, a rotating magnetic field, etc., having a speed of 10 to 10 times faster are also generated at the same time, swing explosively, and the water is vigorously stirred. Here, in addition to far infrared rays, a very wide variety of wave energies ranging from ultraviolet rays emitted by ultra-high temperatures are generated in water. Further, it is considered that the shock wave is generated by a temperature difference between water and the arc. Thus, during the multi-arc, ultra-high temperature electron ions, various temperature ranges, far infrared rays,
Due to the presence of ultrasonic waves, arc ultraviolet rays, shock waves, electromagnetic forces, currents, voltages, rotating magnetic fields, etc., water is affected by these and water quality is modified, and carbon is eluted from the carbon electrode into the water. This means that the quality of the water will also be improved. Therefore, tap water is used as the water 20, and this multi-arc treatment is performed for about 3 hours.
When performed for 0 seconds, all the bacteria in the tap water are sterilized with an arc or other bactericidal energy, the impurities are heated and evaporated or disintegrated, and the water becomes very pure water. If a small amount or even a few drops of the water subjected to the multi-arc treatment is added to tap water in a cup, the water becomes very delicious water free of impurities and odor.
This is thought to be because the water subjected to the multi-arc treatment has fine particles of water approaching the original water and has been given the wave energy generated by the multi-arc, so that it is given to other water molecules. . In fact, the angle of the two Hs to O of the multi-arced water molecule is smaller than that of the non-multi-arced water, and the two Hs to O as well as the water surface on which the multi-arced water is dropped. NMR shows that the angle formed by
(The magnetic resonance) is observed. In addition, the theory of bacteria has confirmed that water is formed by combining several primitive particles of H ₂ O to form water. It has also been confirmed that today's water, which is polymerized, is dismantled and reformed with various energies generated by the generation of a multi-arc in water.

[0012] The water subjected to the multi-arc treatment is also very good for human health. For example, if the water is contained in a gauze and applied to the affected part when it is injured, it will heal very quickly, It has been demonstrated that stiff shoulders can be cured by exposure to water and that drinking this water can be very energetic. In addition, it has been proved that multi-arc water not only has the ability to make an acidic substance alkaline, but conversely, a strongly alkaline substance has the energy to make it more acidic and neutral.

Further, in this underwater multi-arc,
It is considered that a large amount of ions and electrons are generated in the water flow due to the multi-arc between the carbon electrodes, but the atoms of carbon itself are reduced, and this is due to the fact that C jumps out of the carbon electrode to generate CO. it is conceivable that. In this multi-arc, the temperature of the multi-arc is extremely high as described above, but the temperature of water rises only slightly. In this multi-arc, water is H ₂
And the reaction to decompose into O ₂ and the decomposed H ₂ and O ₂ are bonded,
That is, it is considered that the explosion and H ₂ O reaction occur simultaneously.

In the above-described embodiment, the case where a three-phase three-electrode multi-arc is performed has been described. However, a three-phase six-electrode multi-arc or a six-phase six-electrode multi-arc may be used. Further, it is also possible to generate an arc with two or four electrodes using + and-of AC or DC as counter electrodes.

FIG. 2 shows an arc processing apparatus according to a second embodiment of the present invention, in which the ground wire 3d is eliminated in the first embodiment. Therefore, the object to be processed 80
0 is not connected to ground and is not a neutral electrode. This multi-arc uses a three-phase AC power supply, and the sum of the arc current of each phase is always 0, so that an arc is generated even without a ground wire.

In the first and second embodiments, the electrode 1
A storage member 700 that absorbs a gas such as oxygen or hydrogen is provided around a to 1c, thereby storing oxygen or hydrogen, taking it out of the water tank 30, and taking out oxygen or hydrogen or the like therefrom. . In addition, as the storage member, a storage member that stores only one kind of gas of oxygen or hydrogen may be provided, or two types of storage members may be provided at the same time. However, in the case of obtaining drinking water, it is preferable that oxygen be introduced into the water, and it is considered that it is better to provide only the hydrogen storage member.

In the above embodiment, a carbon electrode is used as an electrode, and the carbon electrode is dissolved in water to help improve water quality. However, activated carbon is used as a substance for improving the water quality. Alternatively, a mineral or the like may be put in the electrode or the water tank.

FIG. 4 shows a third embodiment of the present invention. In the figure, 81 is a phase controller for controlling the phase firing angle of the three-phase alternating current to be supplied, and 200 is a phase controller for the primary iron core.

Reference numerals 1a to 1c denote three electrodes connected to the respective secondary outputs, and reference numeral 2d denotes a neutral electrode connected to the neutral terminals of the three primary coils 82, 83, 84. Also, the arc 9 between the electrodes
0 is not normally generated at a firing angle of 120 ° or more, and 500 is a processing unit that performs a multi-arc processing of water.

Shows the sum of the secondary outputs of.

FIGS. 6 (a) and 6 (b) are diagrams for explaining the operating principle of a normal single-wound transformer. Reference numeral 300 denotes a primary coil, from which a secondary output is extracted from an intermediate point thereof. ing. Numerals 310 and 320 denote the resistance of the upper half and lower half of the primary coil 300, respectively.

Next, the operation will be described. In the present embodiment, energization of the three-phase coils 82, 83 and 84 of the autotransformer 200 from the output terminals 1a to 1c of the three-phase AC power supply is controlled by the phase controller 81, as shown in FIG. As shown, each of the coils 82, 83 and 84 has a phase angle of 120 ° to 180 ° of the AC sine waveforms X, Y and Z of each phase (c and f for X, b and e, Z for Y). In the case of (1), energization is performed only in a and d), and each coil is in an open state at other times.

Thus, the three-phase coils 82, 83,
When the energization is repeated in sequence at 84, the iron core becomes as shown in FIG.
Since the magnetic flux having the triple frequency drooping characteristic as shown in FIG. 7 is induced, and the secondary output of the single turn transformer 200 is taken out from the intermediate point of each of the primary coils 82, 83 and 84, each of the electrodes 1a to 1 Each of the sawtooth waves having the drooping characteristics shown in FIG. 5B flows through 1c, and an arc current having a triple frequency flows as a whole. In this case, by adjusting the input on the primary side, various secondary composite wave outputs can be obtained, and a wide arc adjustment can be obtained. Thereby, an appropriate arc can be generated according to the water quality.

In this embodiment, the following effects can be obtained.

In this embodiment, a single-phase iron core transformer is used. However, when a current of 10 A flows through the primary winding as shown in FIGS. In addition, a current of 20 A is obtained in the secondary output, and a single-winding transformer without a secondary winding is used, so that a significant reduction in size and weight can be achieved.

Since the power supply used in this embodiment has the drooping characteristic as described above, in order to obtain the drooping characteristic, a leakage flux type device generally used or a saturable reactor L has been conventionally used. It is not necessary to use such a method, and there is no accompanying loss or reduction of the power factor.

Also, since the frequency obtained is tripled,
The transformer becomes smaller, the weight is reduced to one third of that of the conventional one, and it becomes very small and light. Further, since the structure of the transformer is simple and small and lightweight, the manufacturing cost can be greatly reduced.

By appropriately adjusting the firing angle of the AC sine waveform of each phase, the arc intensity can be largely adjusted.

In the above-described embodiment, a three-phase output is obtained using a single-winding transformer, and multi-arc is performed using the three-phase output. Three coils are wound, and one secondary coil is wound on the secondary side, and the output of the triple frequency and sawtooth wave shown in FIG. 5B is taken out from the secondary coil, and is output between the two electrodes. Between electrodes (two electrodes have the same potential), between six electrodes (three electrodes have the same potential)

The multi-arc generator used in the present invention has the following features.

An ultra-high temperature arc carrying negative electron ions is generated regardless of whether it is in air, liquid, or vacuum.

Since a heat source of 4,000 ° C. or more can be obtained at the same time when the switch is turned on, a high melting point substance can be melted and dissolved.

Since a rotating magnetic field is generated at the tip of the electrode,
It can be expected that an electric stirring action will be applied to the secret irradiation object.

The number of phases and the number of electrodes can be increased by a multiple of 3, and the electrode diameter can be increased, and the load current can be increased to process a large-capacity substance in a short time.

A multi-phase alternating current such as three-phase or six-phase is used.
Since the total current of each phase is always 0 and a ground wire is not required, the arc is non-transitional and does not require a counter electrode such as a counter electrode. Therefore, it is necessary to use a material other than metal as the counter electrode. Therefore, refractories having no conductivity can be directly heated, sintered and melted.

By providing a neutral electrode at the center of the plurality of electrodes, a more cooperative plasma arc is generated.

Instead of providing the above-mentioned neutral electrode, a solvent or gas or the like can be discharged from the central portion.

Next, the operation will be described. In this embodiment, the water 20 is put into the container 30 through the inlet 31 so that the non-consumable electrodes 1 a to 1 c made of at least three carbon members are immersed in the water 20. Next, 3

0 occurs. This plasma arc is compressed by water pressure, but its temperature reaches an extremely high temperature of about 11,000 ° C., and due to this heat, the water 17 is locally heated and boiled to be steam or to be decomposed into hydrogen and oxygen. It causes bubbles. Further, when this plasma arc is generated, far infrared rays, ultrasonic waves, light, blue light of the arc, shock waves 5 to 19 times faster than the sound waves, rotating magnetic fields, and the like are also generated at the same time. Will be agitated.

As described above, in the multi-arc, ultra-high temperature electron ions, various temperature ranges, far infrared rays, ultrasonic waves,
Due to the presence of light, ultraviolet rays of an arc, a shock wave, a rotating magnetic field, and the like, the water 20 is affected by these substances, and the water quality is modified. By dissolving in water, the water 20 will also have improved water quality. The water 20 treated by this multi-arc is a faucet 33
Can be taken out of the appropriate amount.

In this way, the treatment and reforming of the water by the multi-arc are performed. As the arc is generated, the tips of the electrodes 1a to 1c are gradually consumed. When the tip of each of the electrodes 1a to 1c is consumed to some extent, the distance between the electrodes 1a to 1c increases, and the arc 9
0 is weak or no longer occurs.
