Description

[Detailed description of the invention]

The present invention relates to a magnetization device that applies magnetism to iron contained in a liquid, and in particular, applies magnetism to iron contained in ionic form in liquids such as brewing water, covalently bonds it, and coarsens the particles. This invention relates to a device for magnetizing iron in a liquid, which allows iron to be easily and almost completely removed by a subsequent filtration system. In the following explanation, using brewing water as an example, the quality of the fermentation state in brewing is determined by the quality of the brewing water. The conditions that should be provided for brewing water are, of course, that it complies with the water quality standards for tap water, but also the content of metals such as iron and manganese, which can significantly deteriorate the quality of brewed products, and the amount of organic matter to satisfy the requirements for clear water. etc. must be kept particularly low. Since the amount of iron necessary for the growth of yeast is sufficiently supplied from the raw material grains used, water that does not contain any iron is considered suitable water for brewing. In other words, the iron content in the water called suitable water is
0.02ppm or less is desirable, and if it contains more than 0.05ppm, iron and bacteria will combine,
Currently, the brewing industry is working hard to completely remove iron, since bacteria that are harmful to fermentation can grow and the product tends to deteriorate. Iron in water comes in many forms, including suspended fine particles such as iron hydroxide, low-molecular-weight ionic materials, and high-molecular-weight materials combined with organic matter such as humic substances in the form of complex compounds. There are various iron removal methods, and the current iron removal methods include aeration method, sand filtration method, contact oxidation method, and ferrous hydroxide method in which ferrous iron in water is oxidized with chlorine. There are chlorine oxidation methods that remove iron as di-iron, flocculation methods that use chemicals, filtration methods that use activated carbon or granulated carbon, ion exchange resin treatment methods, etc., but these filtration methods alone cannot be expected to remove iron sufficiently. is the current situation. In particular, it is considered extremely difficult to remove low molecular weight ionized iron. Recently, iron removal methods using electromagnets or permanent magnets have been developed, and the present invention provides a device for magnetizing iron in liquid that allows more efficient removal of ionic low molecular weight iron using permanent magnets. It is related to. Conventional methods of magnetizing iron in liquid using permanent magnets have mostly involved passing the liquid through a single permanent magnet at a slow speed to impart magnetism, and it has not been possible to provide sufficient magnetization to the iron in liquid. The present invention allows the liquid to be treated to pass repeatedly between multiple permanent magnet bodies arranged in parallel with a predetermined gap, thereby highly efficiently magnetizing the iron in the liquid. It is an object of the present invention to provide a device for magnetizing iron in a liquid, which is capable of magnetizing iron in a liquid. More specifically, the present invention includes an outer cylinder in which a lid body having a liquid inflow port formed in an opening at one end is fixed, and a lid body having a liquid outflow port formed in the other end opening is fixed. , an inner cylinder located approximately at the center of the outer cylinder, having an opening at one end connected to a liquid inlet formed in the lid, and having a number of liquid passage holes perforated on the circumferential surface; , a large number of annular permanent magnets arranged on the outer periphery of the inner cylinder via gap retainers, an inner partition plate that partitions a liquid flow path in the inner cylinder, and a space between the outer cylinder and the inner cylinder. The liquid flowing into the inner cylinder from the inlet is made to pass between the annular permanent magnet bodies multiple times to remove the liquid contained in the liquid. 1. A device for magnetizing iron in a liquid, characterized in that it promotes magnetization of iron in a liquid. According to the present invention, by providing the gap holder between the permanent magnet bodies, the flow rate of the liquid can always be kept smooth, and the gap holder provides the space between the permanent magnet bodies. Since the liquid flows uniformly through the gap where the magnetic field is strongest and in a state perpendicular to the magnetic field, it is characterized by high magnetization efficiency. After about 24 to 48 hours, the magnetized liquid treated with the apparatus of the present invention becomes cloudy compared to the liquid before passing through the magnetic field. This phenomenon is caused by the ionized iron in the liquid becoming magnetic and becoming larger particles.By passing this magnetized liquid through a precision filtration system in the next step, the coarse particles of iron that become cloudy are removed. Removes the iron content in the water and makes it suitable for brewing water
It becomes possible to remove it down to 0.02ppm or less. Hereinafter, a specific configuration of the present invention will be explained in detail based on illustrated embodiments. FIG. 1 is a longitudinal sectional view showing an embodiment of the device of the present invention, and 1 in the figure indicates an outer cylinder. Reference numeral 2 denotes a lid fixed to an opening at one end of the outer cylinder 1, and a liquid inlet 3 is bored approximately in the center of the lid 2.
4 indicates a lid fixed to the opening at the other end of the outer cylinder 1;
A liquid outlet 5 is provided approximately in the center of the lid 4 . 6 is a long fixing rod that connects the lid 2 and the lid 4 and fixes the outer cylinder 1, the lid 2, and the lid 4 in a watertight manner, 7 is an annular O-ring, and 8
9 indicates a connecting member screwed onto the inlet 3 of the lid 2, and 9 represents a connecting member screwed onto the outlet 5 of the lid 4. Reference numeral 10 denotes an inner cylinder located approximately at the center of the outer cylinder 1, and a large number of liquid passage holes 11 are bored in the circumferential surface of the inner cylinder. A male screw is formed on the outer periphery of both ends of the inner cylinder 10, and one end is screwed into a female screw formed on the inlet 3 of the lid body 2.
The other end is screwed into a female screw cut into the holding body 12. Reference numeral 13 denotes a large number of annular permanent magnet bodies arranged on the outer periphery of the inner cylinder 10 with gap holders 14 in between, and each permanent magnet body 13 is arranged so that the S pole and the N pole face each other. be. The gap holder 14 is a second
In the case of the embodiment shown in Figures and Figure 3, the permanent magnet body 1
It has approximately the same outer diameter shape as 3, and has several protrusions 15 protruding from both sides on its flat surface, and several claws 17 on the inner periphery of a through hole 16 bored in the center. It is formed by bending it. Permanent magnet 1
By interposing the gap holder 14 between the three permanent magnet bodies 13, there is a slight gap 18 between the permanent magnet bodies 13.
At the same time, a slight gap 19 is created between the inner circumferential surface of the permanent magnet body 13 and the inner tube 10 due to the claws 17 coming into contact with the outer circumferential surface of the inner tube 10. Note that the structure of the gap holder 14 is not limited to the embodiment shown in FIGS. 2 and 3;
In short, as long as there is a slight gap between adjacent permanent magnet bodies 13 and between the inner circumferential surface of the permanent magnet bodies 13 and the outer circumferential surface of the inner cylinder 10, it is possible to A plate-shaped one may also be used. Reference numeral 20 denotes a liquid passage 21 in the inner cylinder 10.
22 is an inner partition plate that separates the outer cylinder 1 and the inner cylinder 1.
This is an outer partition plate that partitions a liquid flow path 23 formed between the two. In the illustrated embodiment, a large number of permanent magnet bodies 1 are arranged.
The outer partition plate 22 is fixed in a watertight manner at a position that substantially divides the flow path 23 into two blocks, and the outer partition plate 22 is also fixed in a watertight manner on the side of the outlet 5 to divide the flow path 23 into two blocks. None, internal partition plates 20,
20 are fixed in a water-tight manner, but the number of inner first plates 20 and outer partition plates 22 and the length of each block can be changed as appropriate. Note that the outer partition plate 22 placed on the outlet 5 side is
By screwing the suppressing body 12, it is sandwiched and fixed between it and the permanent magnet body 13 at the rear end. In addition, the inner cylinder 10 whose one end is screwed to the inlet 3 of the lid body 2 is connected to the outer partition plate 2.
2 and 22, it is held approximately at the center inside the outer cylinder 1. In using the apparatus of the present invention, first, a stock solution tube is connected to the connecting member 8, and the stock solution before treatment is supplied into the inner cylinder 10 from the stock solution tube. The stock solution flows through the flow path 21 toward the first inner partition plate 20, but the inner tube 1
Since a large number of communication holes 11 are formed on the circumferential surface of the tube 0, the stock solution passes through the communication holes 11 and enters the communication path 23 located between the outer cylinder 1 and the inner cylinder 10. At that time, the stock solution passes through the gap 18 between the permanent magnets 13, and the maximum magnetic field of the permanent magnets 13 (in this example, the outer diameter is 80
mm, inner diameter 40mm, thickness 10mm, using a 360K/G permanent magnet) in a fan shape and perpendicular to the magnetic field, so it receives the strongest magnetism. In addition, since the gap holder 14 has the claws 17 bent as described above, a slight gap 19 is also obtained between the permanent magnet body 13 and the inner cylinder 10, and the undiluted solution on the outer periphery of the inner cylinder 10 is This will help ensure a smooth circulation. The undiluted solution that has entered the flow path 23 is prevented from going straight by the outer partition plate 22 and returns to the flow path 21 in the inner cylinder 10 through the maximum magnetic field between the permanent magnets 13 again. Then, the stock solution enters the second block bordered by the outer partition plate 22, passes through the flow hole 11 in the inner cylinder 10, moves through the flow path 23 in the outer cylinder 1, and passes through the outer partition plate at the rear end. 22, the gap 1 between the permanent magnet bodies 13 is again
8 and enters the final flow path 21 in the inner cylinder 10, and is discharged outside the apparatus as a magnetized liquid through an outlet 5 formed in the lid 4. According to the present invention, the undiluted solution can smoothly flow through multiple maximum magnetic fields in a fan shape and perpendicularly to the magnetic fields, and by passing through the magnetic fields multiple times, a large amount of magnetic fluid can be reliably passed through in a short period of time. , which can be obtained without changing the water quality like iron removal using chlorine oxidation method or chemical flocculation method, converts the ionic low molecular weight iron in the stock solution into polymeric particles, and then processes it in the next stage of precision filtration. This makes it possible to easily remove iron. Table 1 below shows the iron content of three types of raw water before treatment, each with a different iron content, when it is directly subjected to ceramic filtration treatment, and when it is treated with the device of the present invention and then subjected to ceramic filtration treatment. This is a comparison of their respective contents. In this example, the outer diameter is 80 mm, the inner diameter is 40 mm, and the thickness is 80 mm.
A 10mm, 360K/G permanent magnet was used. As shown in Table 1, if the iron content in the raw water of type 3 is about 0.25 ppm, the iron content will not be detected even after passing through the magnetic field between the permanent magnets of the present invention twice, followed by ceramic filtration once. It is possible to remove iron up to Considering this iron removal theory, it is due to covalent addition of ionic iron present in raw water under the influence of the magnetic field of a permanent magnet, and the form of covalent addition is as shown in Table 2. Become. If the covalently bonded iron molecules form two or more molecules due to the magnetism they receive when they pass through the magnetic field between the permanent magnets, the magnetic field will be at least 0.4μ.
This is greater than the filtration capacity of a filter (diameter 4.0 x 10 ^-7 mm), so it is removed with a 0.4μ filter. If the water is filtered using a 0.2μ filter (diameter 2.0 x 10 ^-7 mm), all covalently bound iron will be removed and only ionic iron will remain in the water. Table 3 below shows the content of Fe ²⁺ when raw water is passed once between the permanent magnet bodies of the present invention and then filtered through a 0.2μ filter. As shown in Table 3, it can be seen that the Fe ²⁺ content decreases as time passes. Therefore, it can be seen that it is desirable to filter the water that has passed through the magnetic field between the permanent magnet bodies as long as possible. Considering the above test results as a whole, when water passes through the magnetic field between the permanent magnets of the present invention, the influence of iron in the water is due to the effect of covalently bonding Fe ions, and the effect of covalently bonding Fe. Possible actions include an action of aggregating Fe 2+ , and an action of aggregating Fe ²⁺ using methods described above and other methods to increase its diameter. Therefore, as shown in Table 1, after the magnetic field between the permanent magnet bodies of the present invention is passed through water,
By filtering with a 0.2 to 0.4μ filter, the iron content in brewing water, for example, can be filtered down to 0.02 ppm or less, which is the preferred water.
