Abstract

PURPOSE:To make the captioned unit smaller, thereby reducing its weight by stacking a plurality of permanent magnets through soft steel plate. CONSTITUTION:Reducers 5 of round and square sections are connected to a large-sized pipe 6, thereby constituting a magnetic field treatment section 3. In this section 3, a number of ansotropic permanent magnets, which are arranged like a lattice work on both sides of a mild steel plate 2 at its center, are laidout in parallel and stacked like a sandwitch. Adjusting plates 4 are placed on the magnets, and magnetic control is so performed that proper flux density may be adjusted between magnetic poles. At the same time, improper magnetic fields on both sides of a fluid pipe is clogged with buffle plates 7. An improvement in combustion efficiency can be attained by providing a proper magnetic field to the fuel flowing inside the large-sized pipe 6 in this manner.

Description

[Detailed Description of the Invention] The present invention relates to a novel structure of a magnetic field treatment device for applying a magnetic field (industrial! This is referred to as a magnetic field) for the purpose of changing the physical properties of fluid in piping, and is characterized by being small and lightweight. However, it can also be used for large-scale piping by incorporating four of them into the piping.

Conventionally, 18% of the liquid fuel in transfer piping for boilers and furnaces has been used.
There is a known method of applying a magnetic field around 0.00 Gauss to enhance the combustion effect and save fuel, but it has been found that the same method is also effective for engines using liquid fuel. Ta. However, the conventional type was large in both weight and bulk, so it could not be used in the engine room.

Here, a conventional magnetic field processing device or magnetic field generating device for applying a magnetic field to a fluid in a pipe will be explained with reference to the drawings.

The type shown in FIG. 1 consists of a permanent magnet 1 placed in contact with an NS polar core 2, and a connecting piece 3 that connects the permanent magnet 1. In addition, there is also a structure in which the permanent magnet 1 except for the upper connecting piece 3 is arranged symmetrically with the lower permanent magnet 1 so as to prevent magnetic flux leakage from the upper part of the pole core 2. This method applies a magnetic field to the inside of the tube through the non-magnetic tube 4.

The model shown in Figure 2 is the patent application Showa 5l-64353 (Showa 56
The pole core 2 is attracted to the end of the semicircular permanent magnet 1 by the method shown in Japanese Patent Publication No. 5439), and the polar core 2 is attracted to the steel pipe 3.
This method applies a magnetic field to the fluid inside the pipe through a steel pipe, but since the magnetic lines of force pass through the thick part of the steel pipe and flow in the direction of S from N, the magnetic field inside the pipe is considerably demagnetized, and the strength of the magnetic field inside the pipe depends on the outside diameter and thickness of the pipe. , there is a fatal flaw that makes it difficult to obtain an appropriate magnetic field, which will be described later, since it is greatly affected by the length and other factors. Furthermore, it is not possible to apply a magnetic field of 1800 Gauss using this method to the outside of the upper claw, which has a small diameter and little thickness, so this structure is not relevant to the present invention.

The type shown in FIG. 3 is the method shown in Japanese Utility Model Application No. 48-850134, in which a permanent magnet 1 is used as a pole face, a core 2 is connected to the back face of the permanent magnet 1, and a pipe 3 is sandwiched between the poles. When the pipe is a steel pipe and a non-magnetic pipe, the strength of the magnetic field inside the pipe is different, but as will be described later, there is a defect that the distribution of the strength of the magnetic field inside the pipe is not uniform.

The method shown in FIGS. 2 and 3 cannot be used as is in N because the magnetic field processing device requires a uniform magnetic flux density distribution within the tube due to the phenomenon described later.

Next, we will explain the appropriate magnetic field necessary to promote the combustion reaction.4 Figure 4 was created by the Central Research Institute of Electric Power Industry in March 1978.
This was published in the Monthly Research Report 277025, and is about the relationship between magnetic field strength and soot and dust for C heavy oil.

Soot and dust are indicators of combustion conditions; less soot and dust for the same fuel means that it burns better, and more soot and dust means that it burns less.

In FIG. 4, D shows the soot and dust V in the combustion exhaust gas, B shows the Gaussian magnetic flux density at the center of the magnetic field, N shows the case without a magnetic field, and M shows the case where a magnetic field is applied.

In addition, in the diagram, the curve rises and falls when there is no magnetic field because there is a change in the amount of air, and the way to look at the diagram is that there is a large difference in soot and dust when there is no magnetic field and when a magnetic field is applied, based on the magnetic flux density. It turns out that there is a big reaction. From the figure, 1800.2500 gauss is an appropriate magnetic field that improves combustion, and 2300 gauss is an inappropriate magnetic field that worsens thermal sintering. Since a high magnetic field requires a large device, we will discuss below 2000 Gauss.

According to FIG. 4, a magnetic field between 1,400 and 1,600 Gauss has not been tested, but even if it is actually used, a stable effect cannot be obtained and the magnetic field is unstable. Therefore, the range that can be used industrially is between 1600 and 1800 Gauss, and the acceptable range is 200 Gauss.
For the sake of certainty with Gauss, I would like to use 150 Gauss.

Next, in a magnetic field processing device using permanent magnets, the properties of the magnets must be taken into consideration. This may occur if the strength of the magnetic field decreases while using the magnetic field processing device. Causes of this include friction between the back of the magnet and the mild steel core that makes up the magnetic field line circuit, temperature rise, vibration, and aging, but ferrite magnets are resistant to demagnetization factors other than temperature, so they are used in automobiles. It is ideal for things that vibrate a lot. The drawback is that the temperature changes by 4 Gauss for every ±1°C (variability).

In boilers and furnaces, the annual swing width reaches a maximum of around 35 degrees Celsius.

The temperature in the engine compartment of a car in summer exceeds 50 degrees Celsius, and in winter it may not reach 20 degrees Celsius. Therefore, the above difference 3
At 5°C, there is a difference of 140 Gauss. That is, a tolerance of ±70 Gauss is required. If we assume a measurement and adjustment error of ±3% when assembling the magnetic field processing device, ±3% of the average 1700 Gauss of 1600 to 1800 Gauss is ±51 Gauss.
Therefore, a total tolerance of 242 gauss of ±12υ gauss is required. Since this value exceeds the appropriate magnetic field range of 200 Gauss, it is an absolute requirement for the magnetic field processing device that the magnetic field distribution be uniform.

From the above, it is also a condition that the magnetic field processing device according to the present invention be installed in a non-magnetic tube.

Next, in Fig. 5, in order to give a uniform magnetic field to the fluid inside the tube, the inner diameter of the tube must be made uniform by at least the same amount (d), but in general, the uniform magnetic flux density distribution between the magnetic poles is It is much smaller than the thickness T of pole 7A.

Although there are high-quality permanent magnets that are small and produce a strong magnetic field, ferrite magnets, which are not so strong but are inexpensive and have abundant raw materials, are usually used, so take this into consideration and target a magnetic field of around 1800 Gauss. explain.

For example, an anisotropic ferrite magnet (D
iscn I'
The relationship between the thickness T of the polar core and the uniform magnetic flux density distribution is expressed by the sixth
The result will be as shown in the figure.

Figure 6 (■) shows the relationship between the uniform magnetic flux density at the center of the upper and lower homopolar cores and the polar core thickness TIIM. The relationship with the volume V port is shown. However, if the thickness of the polar core is increased,
Although the uniform magnetic flux density increases, the magnetic flux density in the magnetic field decreases, so the magnet must be made stronger. To this end, the method shown in FIG. 1 uses a method of increasing the number of permanent magnet cylinders to increase the magnetic flux density. To take a specific example, in the case of a rubber tube with an outer diameter of 14φ to which a magnetic field is to be applied, the thickness of the tube is 3 mm, and the inner diameter is 8φ. If this value is entered in Figure 6, the thickness of the magnetic pole core will need to be 18 mm.

6. If the thickness of the pole core is 1f3tnH, the weight will be 4.2Ky and the volume will be 600ee, so such a large magnetic field processing device cannot actually be used in the engine room of an automobile. A small boiler requires a support stand, etc., which can get in the way of daily maintenance. If the method shown in FIG. 1 is adopted as described above, the weight will increase considerably.

The method shown in Figure 3 is preferable in order to reduce weight by using two parts, so we modified it a little and separated the core shown in Figure 3 into side plates 2 and bottom plate 3 as shown in Figure 7, and placed an N-8 pole inside the first side plate. For example, anisotropic strontium ferrite permanent magnets 1 are arranged so that they face each other. For example 70 x 50 x 12t(fi)
When two magnets are placed at both poles and set at the center of the magnetic field distribution in the vertical, left and right directions perpendicular to the plane of the paper, i.e. the magnetic core 0, at 1800 Gauss (20°C), the magnetic pole spacing will be approximately 9.6Q-, so the outer diameter Consider the case where a magnetic field is applied to the fluid inside the tube through the stainless steel tube 4 of 22φ×2t. Figure M shows the measurement results of the magnetic flux density distribution in the vertical direction and the right direction of the figure, but as of now, the difference in distribution within the tube is 240 Gauss, so it cannot be used as a magnetic field processing device.

Next ζThis is a general attraction magnet, and an armature is attached to the pole face of the magnet to generate a strong magnetic field at the pole. The armature is 3. At ゛p- or more, the suction force is the highest and constant. Below that, it becomes smaller in proportion to the thickness of the armature. However, it was found that the strength of the magnetic field decreases as the thickness of the armature increases. Therefore, based on the structure shown in Fig. 7, a thin mild steel plate 4 of 35 x 50 el was attached to the center of the magnetic pole face, and the relationship was obtained by changing this thickness, as shown in Fig. 8. In this figure, (b) shows the magnetic flux density at the center of the magnetic field in the MH' direction at a distance Cqng from the magnetic pole face and the center 0
The difference between the values is shown in Gauss, and t is the thickness h# of the mild steel plate attached to the pole surface.
The magnetic flux distribution in the -v' direction is shown, and b represents the length (mm) of the uniform portion.

From the figure, the vertical direction is t -0.2mm and b = 23mm.
This results in a sufficiently uniform magnetic field, and the magnetic flux distribution in the left and right directions is at a level that can be used for practical purposes at 0.4 t.

This has made it possible to accurately apply an appropriate magnetic field to the fluid inside the tube through the non-magnetic tube by using the magnetic pole surface without using a magnetic pole core, and it has become possible to reduce the weight. Hereinafter, this mild steel plate will be referred to as an adjustment plate. Now, when comparing the method in Figure 1 and the method in Figure 8, in the case of uniform magnetic flux density b -29mtn in the method in Figure 1 as shown in Figure 6, the weight is 7.3 K9 and the bulk is 1.
000 cq Ryuuru was able to be made considerably smaller and lighter with the Figure 8 method, weight '2.62Kf bulk 370 (c and weight, 1/4.5 volume, which is about 1/4.5. Figure 9 is Figure 8. The magnetic flux density Bo Gauss at the center of the magnetic field when the thickness of the 35X50 adjustment plate is changed with the magnetic pole distance W!23m constant is determined. In order not only to make the magnetic flux density uniform but also to adjust its strength, the side plates and bottom plate shown in Fig. 8 are formed into a U-shape by pressing as one core, and after placing the magnets [Due to manufacturing irregularities in 6] The strength can be adjusted by adjusting the thickness of the adjustment plate, making it suitable for mass production. For example, as a magnetic field processing device for automobile engines, a magnetic pole spacing of 14 m"h and a 50 x 30 x 12 t (about 4002 can be manufactured using my strontium ferrite) As a result, it can be used in the engine room without the need for support.
B) Use a strong plate magnet to attach the core [U-shaped or U-shaped]
It has become possible to create a magnetic field processing device with a small diameter mold. In both cases, magnet unevenness and magnetic field type can be eliminated by adjusting plates, and the magnetic flux density can be adjusted, making mass production possible.

The above-mentioned lightweight magnetic field treatment equipment is widely used in boilers and furnaces, from small oil fan heaters to large boilers.In particular, it is used for equipment that until now required mounting stands and supports, and even for alligator piping without support. It is easy to install with a hose band. For automobile engines, 10 mode fuel efficiency is 11.5
&/j' When installed on the rubber pipe of the carburetor's fuel pipe in a 1600ccN car, the actual fuel consumption of 1q5 4 increased to 12.5 K, /i.

In FIG. 10, 1 is a permanent magnet, 2 is a core, 3 is an adjustment plate, 4 is a pipe support, and 5 is an oil transport pipe.

Next, the case where the device of the present invention is applied to a large diameter pipe will be explained. Figure 11 is an example of its application, and (A) is a cross-sectional view (B
) is a secondary sectional view. A circular pipe with different diameters 5 is attached to a large diameter pipe 6, and a magnetic field processing device section whose outer frame is made of mild steel connecting pieces 2, 3.3 is connected. In this part, a large number of anisotropic permanent magnets arranged in a lattice pattern on both sides of the mild steel plate 2 are arranged in parallel in a sandwich style, and an adjustment plate 4 is placed on top of the magnets to adjust the magnetic force. Therefore, by adjusting the magnetic flux density between the magnetic poles to an appropriate value and blocking the inappropriate magnetic field portions on both sides of the fluid passage with baffle plates 7 so that 4° of fluid passes between these poles, an appropriate magnetic field will be created for the fluid passing through the large diameter pipe. can be given. This method was published in Japanese Unexamined Patent Publication No. 4)7, -51-
8! Although it resembles the casing shown in the '224 publication, it is completely different, and is intended to be a lightweight magnetic field processing device that applies an appropriate magnetic field to a fluid using a combination of a magnetic circuit and an adjusting plate. be.

In particular, ferrite magnets can only have a size of about 100 degrees of angle at most, so when magnets are arranged in a grid, adjacent magnets push each other against each other, creating gaps between the magnets, which causes the magnetic field to become strong and uneven. The adjustment plate has the effect of alleviating and almost evening out the unevenness, making it indispensable for large-scale magnetic field processing equipment.

The above example describes the use of sintered or metal permanent magnets, but
Depending on the strength of the magnetic field, plastic plate or film-like strip permanent magnets can be used in a similar manner.

Magnetizing the combustion air of boilers and furnaces promotes combustion, suppresses soot generation, and improves thermal efficiency, but it is also used to magnetize air or gas in this way.
