[0002]

2. Description of the Related Art The pH of conventional tap water is usually neutral, but it may become weakly acidic due to the effects of carbon dioxide and acid rain in the atmosphere, and contains chlorine ions for disinfection. Sometimes.

[0003]

However, when water containing chlorine ions or weakly acidic water flows in the water pipe, there is a problem that rust is generated on the inner wall surface of the water pipe and the water flowing in the water pipe becomes turbid. . In particular, rusting was severe at the joints of water pipes.

Here, the magnetic field generating means includes a plurality of magnet units circumferentially arranged in the flow path at predetermined intervals, and the magnet units include a yoke member and a magnet laminated in the water flow direction. It is preferable that the magnetic poles of the magnet units adjacent to each other have opposite directions.

As a result, it is possible to increase the magnitude of the magnetic field without disturbing the flow of the water flow simply by increasing the number of laminated magnets, and the magnetic field in the water flow direction generated by the magnet is applied to the yoke member. At this position, it is possible to change the direction of the water flow in the direction perpendicular to the water flow and allow the water to permeate through the water flow, thereby increasing the Lorentz force applied to the water flow.

Further, it is preferable that the turbulent flow plate is a ferromagnetic material extending radially from the center of the circumference of the flowing water pipe between the magnet units.

This makes it possible to concentrate the magnetic field on the water flow diffused by the turbulent flow plate while increasing the velocity of the water flow at the position of the turbulent flow plate, while suppressing the pressure loss in the pipe. The plate and the magnet unit can be efficiently arranged in the pipe, and the water treatment device can be made compact without degrading the performance of the water treatment device.

Further, it is preferable that the turbulent flow plates are arranged at irregular intervals in the water flow direction.

As a result, a turbulent flow can be effectively generated with respect to the water flowing in the pipe, and the Lorentz force applied to the water flow can be increased.

Further, it is preferable that the turbulent flow plate is subjected to an oxidation resistance treatment.

The magnetic force of the magnet unit is 600 gauss or more, and the flow velocity of the water flow is 0.2 m / sec or more.
It is preferably 5 m / sec or less.

As a result, the water flowing in the flowing water pipe can be effectively alkalized and the generation of rust on the inner wall surface of the pipe can be suppressed.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram showing an operation principle of a water treatment device according to an embodiment of the present invention. In FIG. 1, a flow path 7 is provided between the magnet units 1a and 1b, and a water flow 5 can flow between the magnet units 1a and 1b. The magnet units 1a, 1b are provided with yoke materials 2a, 2b and magnets 3a, 3b, and the yoke materials 2a, 2b and magnets 3a, 3b are stacked in the direction of the water flow 5. Here, the magnetic force of each magnet 3a, 3b can be about 800 to 1200 gauss, and the magnetic force can be 250 by stacking the magnets 3a, 3b.
It is preferably about 0 gauss.

As a magnet material for the magnets 3a and 3b,
Ferrite magnets (barium ferrite, strontium ferrite, etc.), rare earth magnets (samarium / cobalt magnets, neodymium / iron / boron magnets, etc.) can be used. As the yoke materials 2a and 2b, ferrite, pure iron, iron-silicon alloy, iron-nickel alloy, iron-chromium alloy, iron-cobalt alloy, sendust, etc. can be used.

The directions of the magnetic poles of the magnets 3a and 3b are set to be opposite to each other between the magnet units 1a and 1b. As a result, the magnetic field flowing out from the yoke material 2b of the one magnet unit 1b can be absorbed by the yoke material 2a of the other magnet unit 1a to form the magnetic path 6 circulating between the magnet units 1a and 1b. As a result, a magnetic field can be applied vertically to the water flow 5 passing between the yoke members 2a and 2b, and the Lorentz force applied to the water flow 5 can be increased.

By increasing the number of stacked magnets 3a and 3b, the magnetic force generated by the magnet units 1a and 1b can be easily increased, and the Lorentz force applied to the water flow 5 can be increased. . Here, since the magnets 3a and 3b are laminated in the direction of the water flow 5, it is possible to prevent the flow of the water flow 5 from being obstructed even when the magnetic force generated by the magnet units 1a and 1b is increased. A turbulent flow plate 4 for diffusing a water flow 5 passing between the yoke members 2a and 2b is provided between the magnet units 1a and 1b. With this turbulent flow plate 4, the yoke material 2a,
It is possible to increase the flow velocity of the water flow 5 passing between the yoke members 2a and 2b by generating a turbulent flow in the water flow 5 passing between the water flows 2b, and to increase the Lorentz force applied to the water flow 5. . The material of the turbulent flow plate 4 is preferably a ferromagnetic material, and for example, iron or stainless steel 430 can be used. Further, in order to prevent the turbulent flow plate 4 from being rusted, the turbulent flow plate 4 may be subjected to an oxidation resistance treatment. Here, as a method of oxidation resistance treatment, in addition to a method of coating fluororesin (Teflon etc.), plating treatment, heat treatment (nitriding treatment, vacuum heat treatment etc.), vacuum thin film forming treatment (vacuum evaporation, sputtering, CVD) etc. Can be used.
In addition, the oxidation resistance effect may be obtained by changing the surface texture or surface condition of the material, or the surface may be passivated.

Lorentz force is generated in the water stream 5,
By generating an electromotive force, the redox reaction can be promoted and the water flowing in the pipe can be alkalized, and the generation of rust on the inner wall surface of the pipe can be suppressed. Further, by making the water flowing in the pipe alkaline, it becomes possible to form magnetite on the surface of the inner wall of the pipe, and it is possible to prevent corrosion of the water system pipe and tank using the steel material.

The water inspection result on the 11th day after the start of operation showed that the water in the circulation tank 81 became completely transparent.

When the operation was carried out at a flow rate of 2 m / min for about 13 hours per day, it was confirmed that magnetite was formed on the 5th day. When the operation was performed at a flow rate of 1.3 m / min for about 13 hours a day, it was confirmed that magnetite was formed on the 10th day.
Here, the experiment was performed with the standard value of the Japan Water Works Association.

From the above experimental results, it is possible to make water alkaline by passing the water through the water treatment device 83, and to prevent the generation of red rust on the inner wall surface of the tube by magnetizing the inner wall surface of the tube. I understand.

As described above, according to the present invention,
While applying a vertical magnetic field to the water flow in the pipe,
It is possible to increase the flow velocity of the water flow flowing through it, and the electromotive force generated in the water flow accelerates the redox reaction, making it possible to alkalize the water flowing in the water flow pipe. It is possible to suppress the corrosion of the water system pipes and tanks.

Further, it becomes possible to efficiently arrange the turbulent flow plate and the magnet unit while suppressing the pressure loss in the pipe in the limited space in which the water flow flows, without deteriorating the performance of the water treatment device. The water treatment device can be made compact.
