Description

The present invention relates to a water treatment method and a water treatment apparatus for refining the water molecule clusters using the Fleming force by the collapse rupture and magnetic field Ma Ikurobaburu generated by cavitation.

Water cannot exist in a single molecule, but forms a cluster (molecular population) consisting of a large number of molecules by hydrogen bonding. These water clusters vary in size depending on the conditions of their location. For example, natural spring water is thought to have a larger cluster of hydrogen molecules broken, and water molecules surrounding calcium ions, forming smaller clusters than water alone. Water with a small average cluster is physiologically and medically useful to humans, and since it does not contain extra oxygen, it suppresses the growth of microorganisms in nature and preserves a good environment.
Conventionally, useful water with a small cluster on average is, for example, (1) cutting hydrogen bonds by irradiating ultrasonic waves to vibrate water, (2) immersing a ceramic plate in water, Alternatively, by filtering water with a ceramic filter, far infrared rays radiated from ceramics act on water, or (3) an electric field or magnetic field is applied to water like an electrolysis type water purifier (see Patent Document 1) , And so on.
Japanese Patent Laid-Open No. 9-308888

  However, the water of small clusters generated by the above-mentioned means is weak and unstable due to the weak binding force between the water molecules forming the small clusters, and can be restored to a large cluster in several hours to several days. And the problem that it is difficult to produce a large amount at a low cost.

  An object of the present invention is to provide a method and an apparatus capable of producing a large amount of water with a small cluster on average at low cost, which can exist stably for a long period of time.

In order to solve the above problems, the water treatment method of the present invention includes a step of mixing air or ozone bubbles into water flowing at a flow rate of 15 m / sec or more in a water channel, and injection of a high-pressure water jet into the air or ozone bubbles. The method includes a step of colliding microbubbles generated by cavitation, and a step of applying a magnetic field to a region where the microbubbles collide with the air or ozone bubbles to be broken into nanobubbles . Although luma Ikurobaburu be generated in a very short time cavitation is electrically in the insulating body, the individual bubble interface ions and free the electrons are distributed in (electrolytic separation phenomenon), ions and electrons of the cavitation these As a result of collision in a turbulent flow and the occurrence of ionization (impact ionization), it becomes conductive. Ri by that Ma Ikurobaburu tinged the conductivity passes through the magnetic field downstream, acts magnetic field and a direction perpendicular force according to Fleming's left-hand rule to water molecule clusters wrap Ma Ikurobaburu, by the force Water molecule clusters are refined (microclustering). While not pass or passes through the magnetic field, Ma Ikurobaburu is very disintegrated rupture in a short time by the surrounding water pressure and atmospheric pressure, this time, it exerts a strong shock wave around a chain reaction. Although this shock wave is known as a cause of cavitation noise and erosion, the shock wave further refines the water molecule cluster.

Water treatment method of the present invention more as engineering of mixing air bubbles or ozone in the water channel upstream of the high pressure water jet, the miniaturization of the water molecule cluster, the activation of water by the water dissolved oxygen simultaneously realizable.

Further, the water treatment apparatus of the present invention is based on a bubble mixing means for mixing air or ozone bubbles into water flowing at a flow velocity of 15 m / sec or more in the water channel in order from the upstream side of the water channel, and injection of a high-pressure water jet. a cavitation generating means for generating a Ma Ikurobaburu by the cavitation, in that a and a magnetic field forming means for forming a magnetic field in the area to be destroyed nanobubbles microbubbles collides with bubbles of the air or ozone in the water channel Features. Upstream of the cavitation generating means, more Rukoto provided bubbly means of mixing air bubbles or ozone, activation of water by the water of dissolved oxygen can be achieved with respect to the water in the water channel. The magnetic field forming means by Rukoto be placed in an area where the bubbles are destroyed nanobubbles collide with previous KOR Ikurobaburu, miniaturization of ionized water molecule clusters is promoted around nanobubbles.

The present invention is a cavitation by high pressure water injection into the water channel to generate Ma Ikurobaburu in waterways, it is so arranged to apply a magnetic field downstream to call between Ikurobaburu, the ions and electrons distributed in microbubbles interface Ma Ikurobaburu began to take on conductivity by impact ionization, by receiving a magnetic field effect when passing through the magnetic field downstream receives a magnetic field perpendicular to the direction of force by the Fleming's left-hand rule, the force As a result, the water molecule cluster surrounding the bubble is refined. And, the very collapse rupture in a short time by the surrounding water pressure and atmospheric pressure while the Ma Ikurobaburu does not pass or passes through the magnetic field, finer water molecule clusters is promoted by the strong shock wave generated by the collapse rupture The The water molecule clusters thus refined are not easily broken because the bonding state is stronger than that of hydrogen bonds, and can remain stable for a long time as small clusters.

  For this reason, oxygen that was dissolved in large agglomerates in an unstable state between large water molecule clusters before treatment remains in a small amount in a stable and small granular form between microclusters after treatment. . In addition, before the treatment, rot caused by the growth of microorganisms such as aerobic bacteria due to unstable dissolved oxygen, which caused water-bloom in the reservoir, etc., but it was dissolved even if organic matter was contained after treatment. Because there is little oxygen, the activity of bacteria is greatly restricted, the water will not rot, the transparency will not change, and no water will be generated.

  When air (or ozone) bubbles are mixed from the upstream side of the high-pressure water jet, viruses such as koi herpes can be completely killed by the sterilization effect of ozone generated from the bubbles. A mechanism for generating ozone from air bubbles will be described later (see [0018] stage).

  Hereinafter, an embodiment of a water treatment method according to the present invention and a water treatment apparatus used therefor will be described with reference to the drawings. FIG. 1 is a schematic configuration diagram when the water treatment apparatus of the present invention is applied to purify a reservoir. Reference numeral 1 denotes a stainless steel pipe disposed substantially horizontally. The inside of the pipe 1 becomes a water channel for flowing the water of the reservoir 2. The pipe 1 is horizontal in the illustrated example, but there is no particular problem even if it is disposed in an inclined or meandering manner. The material of the pipe 1 is not particularly limited, and is not limited to stainless steel, and other metal or resin pipes can be used. An electromagnetic coil 3 is attached to the outer periphery of the intermediate portion of the pipe 1. This electromagnetic coil 3 uses three-phase 200 volts as a power source, and realizes a maximum of 4 Tesla by incorporating a converter. By the way, in the permanent magnet neodymium, it is at most 1 to 2 Tesla. In addition to the electromagnetic coil 3 alone, a neodymium may be additionally arranged on the downstream side of the electromagnetic coil 3 as necessary. This is to compensate for the effect of the magnetic field when the relatively small electromagnetic coil 3 is used.

  A high-pressure air base 4 and a high-pressure water base 5 are attached to the pipe 1 upstream of the electromagnetic coil 3 (right side of the electromagnetic coil in the illustrated example) in order from the upstream side. The caps 4 and 5 have substantially the same structure as shown in FIGS. 2 and 3, and a pair of left and right female screw portions 4a and 5a into which the male screw portion 1a of the pipe 1 is screwed, and a butted portion 1b of the pipe 1 are circular. It has annular spaces 4b, 5b formed so as to surround in the circumferential direction, and joint holes 4c, 5c communicating with the outside from the annular spaces 4b, 5b radially outward. In the pipe 1 in the high pressure air cap 4, small holes 6 are formed at five locations at equal intervals in the circumferential direction. The number of small holes 6 is not limited to five, and may be an appropriate number. These small holes 6 have a diameter of 0.5 mm, for example, and the axis of the small holes 6 is perpendicular to the axis of the pipe 1 for the convenience of processing, but the axis of the small holes 6 is on the downstream side or the upstream side. There is no particular problem even if it is tilted. In the pipe 1 in the high-pressure water base 5, small holes 7 are formed at five locations at equal intervals in the circumferential direction. The number of small holes 7 is not limited to five, and may be an appropriate number. These small holes 7 have a diameter of 0.5 mm, for example, and the axis of the small holes 7 is inclined 45 ° toward the downstream side with respect to the axis of the pipe 1. The inclination angle is not necessarily 45 °. For example, you may make it incline in the downstream within the range of 30 degrees-60 degrees. In addition, the downstream side of the inclination direction of the axis of the small hole 7 is desirable.

  The distance between the high pressure air base 4 and the high pressure water base 5 is not particularly limited. The mutual space between the high pressure water base 5 and the electromagnetic coil 3 is not particularly limited. However, as will be described later, the electromagnetic coil 3 is preferably disposed within a range in which air bubbles are broken into nanobubbles by the high-pressure water jet ejected from the high-pressure water base 5.

  The upstream end of the pipe 1 is connected to the discharge port 11 a of the water pump 11 via the connecting hose 10. A suction port 11 b of the water supply pump 11 is communicated with the inside of the reservoir 2 through a water absorption hose 12. The downstream end of the pipe 1 is communicated with the reservoir 2 through a drain hose 13. The joint hole 4 c of the high pressure air cap 4 is connected to the discharge port 15 a of the air pump 15 via the connecting hose 14. The joint hole 5 c of the high-pressure water base 5 is connected to the discharge port 17 a of the high-pressure water pump 17 through the connecting hose 16. The suction port 17 b of the high-pressure water pump 17 is communicated with the inside of the reservoir 2 through the water suction hose 18.

  The water treatment apparatus according to the present invention is configured as described above. This water treatment device can be used in two ways. The first usage is a usage in which only the air pump 15 is stopped and all other devices are operated. The second usage is a usage in which all devices including the air pump 15 are operated. First, the first usage will be described, and then the second usage will be described.

First, the water in the reservoir 2 is pumped by the water pump 11 and is preferably flowed through the pipe 1 at a flow velocity of 15 m / sec or more. The reason why the flow velocity is set to 15 m / sec or more is that the water molecule cluster sufficiently receives the force necessary for miniaturization by the magnetic field of the electromagnetic coil 3. The water from pipe 1 is returned to reservoir 2 again. The following water treatment is performed while water passes through the pipe 1.

For the water introduced into the pipe 1, for example, a high-pressure water jet having a pressure of 5.0 MP is jetted to the downstream side at an angle of 45 ° from the small hole 7 of the high-pressure water base 5. Fine fine bubbles Sunawa Chima Ikurobaburu is generated in the water by the cavitation effect due to local high-speed water flow caused by the jet. Entity of this Ma Ikurobaburu includes a saturated steam, a mixture of dissolved gas separated from the water at low pressure (dissolved oxygen, etc.). Ma Ikurobaburu is very occur in a short period of time, and, and disappear collapse in a very short time. Since Ma Ikurobaburu is is an insulator, so to speak "air holes", a is not subjected to the action of the magnetic field by the electromagnetic coil 3 on the downstream side as it is. However, by Lima Ikurobaburu the following behavior changes to the conductor of an insulating material, a water molecule clusters are refined by simultaneously subjected to the action of a magnetic field.

That is, since ions and free electrons are distributed at the interface of each bubble (electrolytic separation phenomenon), these ions and electrons collide in the turbulent flow of cavitation, resulting in ionization (impact ionization). Become sexual. Ri by that Ma Ikurobaburu tinged the conductivity passes through the magnetic field downstream, acts magnetic field and a direction perpendicular force according to Fleming's left-hand rule to water molecule clusters wrap Ma Ikurobaburu, by the force Water molecule clusters are refined (microclustering). And While Ma Ikurobaburu does not pass or passes through the magnetic field, very collapse rupture in a short time by the surrounding water pressure and atmospheric pressure, this time, it exerts a strong shock wave around a chain reaction. This shock wave enables further miniaturization of the water molecule cluster. In this way, oxygen that was dissolved in large agglomerates in an unstable state between large water molecule clusters before treatment remains in a small amount in a stable and small granular state between microclusters after treatment, or at all. Will not.

Next, the 2nd usage of the water treatment apparatus of this invention is demonstrated. In this second usage, air (or ozone as necessary) is blown from the small hole 6 of the high pressure air base 4 at a pressure of 9 kg / cm ² , for example. This air becomes bubbles 21 having a diameter of about 0.5 to 2 mm, for example, and enters the water (see FIG. 4A). The bubbles flow in the pipe 1 along with the water flow toward the downstream side. On the other hand, as described above, from the small hole 7 of the high-pressure water base 5, for example, a high-pressure water jet having a pressure of 5.0 MP is ejected toward the downstream side at an angle of 45 °. By local high-speed water flow by the jet, fine fine bubbles Sunawa Chima Ikurobaburu occurs in the water.

Ma Ikurobaburu is is to disappear destruction within a very short period of time, prior to its destruction annihilation, a relatively large bubbles flowing from upstream, at once nanobubbles size of the bubble call between Ikurobaburu collide at high speed (The peak of the particle size distribution is, for example, 100 to 200 nm) (see FIG. 4B). A sudden adiabatic compression phenomenon occurs when the bubbles 21 are broken into nanobubbles 22, thereby forming an extreme reaction field of ultrahigh pressure and ultrahigh temperature in the nanobubbles 22. In the ultrahigh pressure / high temperature extreme reaction field, water molecules around the nanobubbles 22 are decomposed to form free radicals (hydroxy radicals) such as OH. Further, part of oxygen in the bubbles due to the blowing of air forms O ³ (ozone) by the action of the extreme reaction field.

Free radicals and ozone have an extremely strong oxidizing ability, and this strong oxidizing ability exerts a strong bactericidal, deodorizing and bactericidal action. It has been confirmed that the addition of a small amount of saline to the high-pressure water jet significantly enhances the bactericidal, deodorant and antibacterial effects. This is considered to be related to HClO (hypochlorous acid) and ClO ⁻ (hypochlorite ion), which are generated by some mechanism from saline and have strong bactericidal activity. The saline concentration in water after adding the saline may be, for example, about 0.5%.

In addition, a magnetic field generated by the electromagnetic coil 3 acts in a range where the bubbles 21 are destroyed by the nanobubbles 22 . Although Ma Ikurobaburu and nanobubbles 22 disappears destroyed within a very short time, the force by the Fleming's left-hand rule described in the first usage, the synergy with ultra-high pressure and ultra high temperature extremes reaction field described above The water molecule cluster is further refined. In this way, oxygen which was relatively abundantly dissolved in a large lump in an unstable state between large water molecule clusters before treatment remains in a small amount in a stable and small granular form between the microclusters after treatment.

  As mentioned above, although embodiment of this invention was described, this invention can be variously deformed without being limited to the said embodiment. For example, in the above-described embodiment, the present invention is applied to the purification of the reservoir. However, the present invention can be used for water quality improvement for industrial, medical, or household use, and also for purification of factory wastewater. Is possible. In addition, when the degree of miniaturization of the water molecule cluster varies depending on the application, the present invention adjusts the increase / decrease of the magnetic field of the electromagnetic coil 3 (for example, up to 4 Tesla) by adjusting the injection water amount or injection pressure of the high pressure water jet. By doing so, the cluster size can be changed as appropriate. This allows the range of dissolved oxygen in the water to be adjusted freely, from low oxygen levels that make virus and bacterial activity completely impossible, to high oxygen levels that allow freshwater and seawater fish to grow in the same tank. Various water treatments are possible depending on the application.
