DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of generating a magnetic field in a pipe to ionize and activate a fluid flowing in the pipe, and to form a pipe by a magnetic field perpendicular to the flow direction of the fluid flowing in the pipe. The present invention relates to a fluid ionizer / pipe protector for protecting against scale, corrosion, and the like.

[0002]

2. Description of the Related Art A pipe through which a liquid or gaseous fluid flows gradually deteriorates under the influence of scale, corrosion, microorganisms, etc., depending on the type of fluid. It is said that "pipes are charged" as the cause. For example, in a steel pipe through which water flows, calcium carbonate contained in the water is attracted to the inner surface of the positively charged steel pipe, and calcium salts precipitate on the inner wall of the pipe, forming calcite precipitates, that is, scale, forming water. It will impede the flow.

As an apparatus for preventing the pipe from being charged, there is an apparatus which forms a magnetic field in a pipe and ionizes a fluid flowing therethrough (sometimes called magnetic processing of the fluid). Some of these devices form a magnetic field in the same direction as the direction in which the fluid flows, and others form a magnetic field in a direction perpendicular to the direction in which the fluid flows. In the former case, if the flow of fluid is regarded as the movement of the conductor, no current is generated in the pipe because the magnetic field vector is parallel to the moving direction of the conductor, but the latter is in the conductor because the magnetic field vector is orthogonal to the direction in which the conductor moves. An electric current is generated, and the latter is said to generate a negative charge in the steel pipe. Conventionally, such devices (referred to as a fluid ionization device, a pipe protection device, a fluid magnetic treatment device, and the like) include those shown in FIGS.

In the apparatus shown in FIG. 5, iron pole pieces A and B are provided on the outer peripheral surface of the pipe in contact with the outer peripheral surface.
Permanent magnets C and D such as ferrite ceramics are provided at the end of B, and these permanent magnets C and D are fixed inside a fixture E, and the fixture E is arranged on the opposite side across the pipe F. Pipe F with fixture E of another device
It is attached to the outer circumference. The fixture E is part of a magnetic circuit by magnetically connecting permanent magnets C and D provided inside the fixture E. The fixture E is connected to a pipe by bolts G and screws provided at both ends thereof. It can be fixed to the outer periphery of F. The two magnets C and D of the fixture F are arranged so that the magnetic poles are opposite to each other, and a pipe contact portion O that comes into contact with the pipe F of each pole piece A and B, and one is an S pole The other is magnetically polarized to the N pole, and the magnetic field H in the direction intersecting the flow of the fluid in the pipe F as shown in FIG.
Can be formed. In the pole pieces A and B, the area of the pipe contact portion O is smaller than the area of the magnet contact portion P joined to the permanent magnets C and D.
At the pipe contact portion O.

In the apparatus shown in FIG. 6, substantially cylindrical parts I and J are provided on the outer peripheral surface of the pipe in contact with the outer peripheral surface, and both parts I and J are magnetically coupled by a substantially prismatic bridge K. The joint between each of the components I and J and the bridge K has a concave curved surface so that the substantially cylindrical components I and J can rotate.
In this apparatus, parts I and J can be attached to pipes F having various outer diameters by rotating the parts I and J in the directions of arrows ab in FIG.
Further, in this apparatus, since the parts I and J are magnetically coupled to the bridge K, a component corresponding to the fixture E of the apparatus in FIG. 5 is unnecessary. In this device, a plate-shaped permanent magnet M is sandwiched between one of the components I and J,
The magnet M has a structure in which a pipe contact portion O where the magnets M are in contact with the pipes F of the parts I and J is magnetically poled on one side to the S pole and the other on the N pole. Also, the pipe contact part O of each part I and J
To increase the magnetic flux density at the pipe contact portion O.

[0006]

In the apparatus of FIG. 5, the magnetic flux density from the magnets C and D is increased at the pipe contact portion O by the pole pieces A and B. On the other hand, the narrowing of the magnetic field also causes an increase in magnetic resistance. Therefore, even if the area of the pipe contact portion O is made half the area of the magnet contact portion P, simply doubling the magnetic flux density of the pipe contact portion O cannot be achieved. Can not. On the contrary, when viewed from a magnetic circuit point of view, the thin plate-shaped fixture E to which the two permanent magnets C and D are attached is a negative factor in increasing the magnetic field in the pipe F.

The device shown in FIG. 6 has a large number of components for forming a magnetic circuit, and has a portion that generates magnetic resistance such as a junction between the bridge K and components I and J. However, it is difficult to generate a strong magnetic field in the pipe F. Further, since the permanent magnet M is provided on the component J, the symmetry as a magnetic circuit is lost, which is also a negative factor for forming a uniform magnetic field in the pipe F. In this device, a device in which a permanent magnet M is provided for each of the components I and J has been proposed. However, there is a problem that the number of components increases and the assembly cost increases.
