DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magnetically active material for passing a fluid through a magnetic field space, in particular, making use of a specific magnetic gradient of a permanent magnet to perform a magnetic treatment to prevent the scale from adhering to the inner wall of the flow pipe and to electronically excite the fluid. It concerns the device.

[0002]

2. Description of the Related Art In recent years, removal of scale adhering to the inner wall of a fluid flow pipe, prevention of adhesion of red rust, prevention of slime and bacteria, prevention of generation of algae and mold, prevention of carbon adhesion of engines and burners for improving fuel efficiency, and the like. With the increasing demand for longer life of related equipment and prevention of environmental pollution, there is a growing demand for more efficient magnetic activation devices, and among them, magnetic activation devices using permanent magnets In particular, since external power for applying magnetism is not required and running cost is not required, it is particularly noted.

[0003] In the magnetic activation device, the fluid flowing in the liquid flow pipe 1 is passed through the SS pole magnetic field space of the permanent magnet.
For example, in the case of water (H ₂ O), ion decomposition is promoted by electron excitation, causing a decrease in surface tension and neutralization of pH,
Black rust (Fe) that easily attacks and dissolves crystals of a scale such as CaCO ₃ contained in water and reduces red rust (Fe ₂ O ₃ ) generated on the inner wall of a flow iron pipe or the like and is easily dissolved.
₃ O ₄ ). or,
Regarding fuel, polymer saturated or unsaturated hydrocarbon chains are promoted to be decomposed by electron excitation, resulting in a finely reduced molecular weight.
It is said that the permanent magnet used in these magnetically active devices has the effect of being easily combusted completely and reducing the emission of harmful gases such as carbon monoxide (CO). Whether standards are required or not disclosed remains unclear.

[0004] However, in order to meet the demands of the industry, for example, as shown in FIG. The two divided permanent magnets 21 and 22 are inserted in combination and fixed with the sandwiching material 4 or the divided permanent magnet 21 having a bay-shaped inner peripheral portion formed by embedding a plurality of permanent magnets 2 in the resin 3. 22, surrounding the outer circumference of the liquid flow pipe 1, the divided magnet 21,
There is a magnetic activation device in which the holding member 4 provided on the outer periphery of the screw 22 is screwed and fixed with screws and nuts (not shown). (US Patent
These fluids flow through the liquid flow pipe 1 through the S-pole magnetic field space.

In order to improve efficiency, in addition to the above, permanent magnets are further provided in the liquid flow pipe 1 along a direction intersecting with the direction in which the fluid flows to concentrate the lines of magnetic force, and the magnetic field is increased. A prior art and the like are disclosed in which a fluid flowing at a high density is magnetically processed by passing through a magnetic field. (Japanese Patent Publication No. 7-106352)

In recent years, as shown in FIGS. 5A and 5B, permanent magnets 2 are provided on a flexible support 4a having an angle corresponding to the outer diameter of the liquid flow pipe 1 with an interval. In addition to disposing and fixing with an adhesive or the like, a protrusion fixing portion 5 for suppressing displacement is provided near both ends thereof, and the whole is covered and fixed with a casting resin 3 or the like.
A magnetic activation device mounted and fixed to the outer periphery of the flow pipe 1 has been developed for convenient insertion and is extremely useful. However, the magnetic active device is inserted into the outer circumference of the liquid flow pipe 1 by an attachment portion 6 formed on the support 4a. In the case of attaching and tightening, if the outer diameter of the flow pipe 1 is larger, the closing force is strongly displaced and the stress is applied to the permanent magnet 2, and the protrusion fixing part 5 suppresses the displacement of the permanent magnet 2. However, since the end of the permanent magnet 2 is pressed against the circumferential surface of the cross-section of the flow pipe 1 in an unreasonable and unreasonable state, the permanent magnet 2 has a structure weak against external force. For this reason, it is necessary to prepare a flexible support 4a having an angle for each outer diameter of the flow pipe 1, and the design management becomes complicated, and there is a problem that it is necessary to provide many types and the like. are doing.

Further, in the prior arts of these typical examples, there are many cases where magnetic processing is performed at the SS counter pole using a magnetic field that does not effectively utilize the magnetic flux density generated by the permanent magnet 2. Although it is more effective as a magnetic activation device applied by a simplified and simplified means, it is designed without using an effective magnetic field, and a large amount of scale or the like adheres to the inner wall of the flow pipe 1, so that the original effect is exhibited. The fact is that it has not been done. Therefore, there is a case where the magnet is used as a magnetic activation device using the permanent magnet 2 without considering the technical pursuit of giving an appropriate magnetic field to the magnetic field space for the fluid by the magnetic treatment. It is becoming more complicated.

[0008]

SUMMARY OF THE INVENTION The present invention returns to the origin and is based on basic technical means, that is, magnetically, water is a diamagnetic substance and weak dy.
has the property of being drawn in the direction of decreasing the strength of the magnetic field with a force of n (× 10 ⁻⁵ N) unit, and the flow velocity of the fluid in the flow pipe generally decreases as approaching the pipe inner wall; In addition, technical properties such as the fact that substances having low solubility are apt to precipitate in portions where the flow rate is slow, that is, the property that deposits such as scale easily accumulate on the inner wall of the flow pipe over a long period of time. In view of the background, the material in the portion where the flow velocity is slow acts magnetically in the direction of the central flow region, and a hard scale or slime scale mainly containing calcium carbonate (CaCO ₃ ) or the like and red rust are formed on the inner wall of the flow pipe. The purpose is to suppress the adhesion of the like.

Generally, an electrolyte is separated into cations and anions in an aqueous solution. Therefore, in the presence of a magnetic field, ions in a fluid receive a force in a direction perpendicular to the flow direction and the direction of the magnetic field. It is considered that the forces received by the ions and the anions are in opposite directions, and are easily separated in water, that is, easily dissolved in water.

On the other hand, in the absence of a magnetic field, ions chemically react with other impurities to deposit sediment, or the Coulomb force causes an increase in crystals in the sediment, that is, an increase in the crystal grain size. It is presumed that the synergistic effect causes the scale to adhere to the inner wall of the flow pipe, but the details have not been elucidated.

Accordingly, the present invention forcibly concentrates the substance in the slow flow rate portion into the central flow region by the action of the magnetic field so as to overcome the sedimentation phenomenon that occurs magnetochemically in the slow flow rate portion in the flow pipe. It is an object of the present invention to provide a magnetic activation device capable of suppressing a scale or the like adhering to the inner wall of the flow pipe by causing the flow.

[0017]

BEST MODE FOR CARRYING OUT THE INVENTION (Sample and Measuring Method) A 30 mm long, 25 mm wide, 30 mm long, N pole is magnetized on the flow tube side which is inserted into the outer periphery of a 1-inch glass flow tube. A permanent magnet having a through-hole of 30 mm in length was formed by changing the magnetic flux density gradient (Bx / dx) at the center point of the central flow region of the flow pipe to 3.39 × 1.
^{0 - 3 (T / mm)} [ Sample ^{1], 1.38 × 10 -3 (} T / mm)
[Sample 2], 1.03 × 10 ⁻³ (T / mm) [Sample 3] and 0.1.
Using four points having the characteristic of 79 × 10 ⁻³ (T / mm) [sample 4], the scale and the like of the fluid adhering to the inner wall of the flow tube were measured. In this measurement, under the same conditions for the blank and the sample of each example, J
A filter paper determined by IS is cylindrically arranged and fixed, and a saturated solution of calcium carbonate (CaCO ₃ ) is introduced into a glass tube at a flow rate of 20%.
After continuous circulation operation at L / sec for 200 hours, the filter paper was taken out of the crow tube, dehydrated and dried in a vacuum desiccator, and the residue generated by burning the filter paper was subjected to chemical analysis to calculate calcium (Ca).
Was measured.

(Magnetic characteristics of each sample) Magnetic flux density T (× 10 ^-2 [T]) in the Bx direction for each distance from the radial center point (0 mm) to the inner circumference (12.5 mm) of the flow pipe of each sample. Was measured on the basis of the center point, and the results are shown in Table 1. Also,
The gradient of the magnetic flux density of each of the distance (Bx / dx) value S (× 10 ^{- 3}
[T / mm]) were measured, and the results are shown in Table 2.
In addition, these measurements were performed with a Gauss meter.

[0019]

[Table 1]

[0020]

[Table 2]

(Relationship Between Magnetic Field Force and Magnetic Flux Density Gradient) As can be seen from Tables 1 and 2, B approaches
x The magnetic field force T is strong. Therefore, the mixed pure water of the fluid flowing in the flow pipe arranged within the inner diameter of each sample acts on the central flow region where the magnetic field is small as described above,
It can be guessed that it induces the action of magnetically preventing the stagnation of the flow that has occurred over the inner wall of the flow pipe.
It can be inferred that the larger the gradient (Bx / dx) value S of the magnetic flux density of m is, the stronger the magnetic field lines are and the more the effect is.

(Relationship Between Attached Amount and Magnetic Flux Density Gradient)
Based on each sample described above, for verification, C
As a result of measuring the attached amount of a, it was as shown in Table 3.
The comparative example shows a case where no permanent magnet is used under the same conditions as described above.

[0023]

[Table 3] N = 4

As can be seen from Table 3 above, in each case,
Ca (that is, calcium carbonate) adheres to the inner wall of the glass tube. If the gradient of the magnetic flux density with respect to the central flow region of the mixed pure water is less than 1.01 × 10 ⁻³ (T / mm), that is, in Sample 4, the amount of Ca attached (deposited) is In the case of the gradient, that is, about three times as large as that of the samples 1, 2, and 3. In the case of sample 4, the number of depositions is smaller than that of the sample 4 which does not use a permanent magnet (comparative example) because the magnetic field force is too low and the effect is reduced.
It is considered that no remarkable result has been obtained.
Therefore, the gradient of the magnetic flux density with respect to the central flow region of the saturated liquid of calcium carbonate is at least 1.0 × 10 ⁻³ (T / m
m) or more, it is possible to overcome the deposition and meet the expectation stably.

It is needless to say that the selection of the gradient value of the magnetic flux density needs to be determined by the speed and the flow rate of the fluid flowing in the flow pipe. In the above description, the S-pole is described. However, it goes without saying that the same effect can be obtained by using the N-pole.

(Embodiment of Specific Apparatus) The magnetic flux is transmitted so that the gradient of the magnetic flux density with respect to the central flow region of the fluid in the flow pipe is at least 1.0 × 10 ⁻³ (T / mm) or more. It is configured by magnetizing.
