Description

The present invention relates to a cation-containing microbubble generator and a cation generator.

Microbubbles generated in a liquid containing water reach a temperature of several thousand degrees Celsius and several thousand atmospheres of pressure when they disappear, and the gas molecules inside can be forcibly decomposed. As a result, free radicals with strong oxidizing power are generated. Since these free radicals have strong sterilizing power, liquids containing microbubbles, such as water, are used to sterilize foodstuffs.

Surface tension has a large effect on the disappearance of microbubbles. Due to this surface tension, microbubbles present in the liquid cannot maintain a stable state for a long period of time. This is because the smaller the microbubbles are, the faster they disappear due to this surface tension.

In recent years, it has been found that ions contribute to extending the lifespan of such fine bubbles, more specifically microbubbles or nanobubbles. Nanobubbles are, for example, bubbles with a diameter of less than 1 μm, and microbubbles are, for example, bubbles with a diameter of less than 50 μm. The diameter of the stabilized nanobubbles varies depending on the type of electrolyte and ion concentration, but is approximately 50 to 500 nm.

Ions gather around microbubbles, and in microbubbles at the nanobubble level, a strong electrostatic repulsive force acts on them. This electrostatic repulsive force creates a state in which it balances the shrinking force due to surface tension, resulting in stabilization. Due to this stabilization, living foods such as shellfish can be taken into the body and bacteria in the body can be eliminated. Note that, as a device for generating ions, the device described in Patent Document 1, for example, is known.

In this way, in liquids containing microbubbles, ions are useful for stabilizing the microbubbles, that is, extending their lifespan. By generating ions in a liquid, microbubbles in the liquid can be stabilized. In addition to stabilizing microbubbles, these ions also have advantages depending on the type of ion. For example, a liquid containing one of copper ions and silver ions, which are cations, has an excellent antibacterial effect. Microbubbles themselves are expected to be used in a wide variety of fields such as environmental purification and food, as well as medicine and health. For this reason, it would be desirable to be able to generate a liquid containing multiple types of arbitrary cations in addition to microbubbles, depending on the application or purpose of use.

Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. Note that the embodiments described below are merely examples, including modifications, and the technical scope of the present invention is not limited thereto. The technical scope of the present invention also includes various modifications.

FIG. 1 is a diagram illustrating a configuration example and an application example of a cation-containing microbubble generator according to an embodiment of the present invention.
The application example shown in FIG. 1 is an example in which a cation-containing microbubble generator is used for water treatment in a water facility 1. The cation-containing micro-bubble generator is used to generate multiple types of arbitrary cations and micro-bubbles in water supplied as a liquid from the water facility 1. In other words, it is used to generate water containing multiple types of arbitrary cations and microbubbles. Thereby, the water facility 1 supplies water, which is a liquid useful in fields such as environmental purification, food, medicine, and health.

The water facility 1 is, for example, a water supply facility, a water purification facility, a treated water generation facility, or the like. In water facilities, it is used, for example, to sterilize water and supply minerals. As a result, people who drink tap water have benefits such as blood purification, increased resistance, and promotion of health through the supply of minerals. In addition, tap water has higher cleaning power and stronger sterilizing power, so it also has advantages in that respect. This advantage allows the use of cation-containing microbubble generators in water purification facilities. One of its advantages is that it can create a more desirable environment for plants to grow. For these reasons, a cation-containing microbubble generator may be used in a production facility for the purpose of producing treated water.

The cation-containing microbubble generator includes a metal ion generator 2, a microbubble generator 3, and an overflow pump 4.
The metal ion generator 2 is a cation generator in this embodiment, and is capable of generating multiple types of metal ions as cations in the water flowing from the water facility 1. Generation of cations is performed by passing a current between a positive electrode and a negative electrode. The type of cations to be generated is selected by selecting the positive electrode material used as the positive electrode.

The micro-bubble generator 3 generates micro-bubbles in water in which multiple types of cations generated by the metal ion generator 2 are present. The microbubbles here are microbubbles or nanobulbs.
The micro bubble generator 3 is not particularly limited. In other words, various microbubble generating devices can be used, such as those using a venturi tube method, pressurized melting method, orifice method, those using ultrasonic vibration, and those using a microporous filter. can.

The overflow pump 4 pressurizes water containing microbubbles generated by the microbubble generator 3 and sends it to the water facility 1 . Thereby, the overflow pump 4 circulates the water stored in the water facility 1 back to the water facility 1 via the metal ion generator 2, the microbubble generator 3, and its own overflow pump 4. For this reason, the water flowing from the water facility 1 to the outside of the water facility 1 for treatment will be hereinafter referred to as "circulated water" to distinguish it from the water inside the water facility 1.

With this overflow pump 4, both the metal ion generator 2 and the microbubble generator 3 generate cations and microbubbles in the flowing circulating water. This is to avoid or suppress cations generated at the positive electrode from moving to the negative electrode and disappearing. For this reason, in an environment where water does not flow, the overflow pump 4 is an essential component of the cation-containing microbubble generator. In environments where water flows naturally or for other purposes, the overflow pump 4 is not an essential component.

FIG. 2 is a diagram illustrating a specific example of a metal ion generator that constitutes a cation-containing microbubble generator according to an embodiment of the present invention. As described above, the metal ion generator 2 is a cation generator in this embodiment.
The metal ion generator 2 includes a positive electrode 5, a negative electrode 6, a power supply section 20, a plurality of connection sections that connect the power supply section 20 and the positive electrode 5, and wiring that connects the power supply section 20 and the negative electrode 6. .

The power supply unit 20 is equipped with a DC power supply 10. A negative terminal of this DC power supply 10 is connected to the ground and to a negative connection terminal 16 . A variable resistor 11 and an ammeter 12 are connected in series between the positive terminal of the DC power supply 10 and the positive connection terminal 15 from the positive terminal side. Therefore, the variable resistor 11 is used to adjust the amount of current supplied from the power source 10, and the ammeter 12 is used to check the amount of current.

The negative connection terminal 16 and the negative electrode 6 are connected by wiring. The negative electrode 6 is a plate-shaped member made of stainless steel (SUS), for example.
The positive electrode 5 is formed by forming a plurality of different positive electrode materials 5Cu, 5Mg, 5Mn, 5Na, etc. into a plate shape while electrically insulating them. In the codes such as 5Cu attached to each positive electrode material, the symbol following "5" represents the type of positive electrode material. Therefore, for example, "5Cu" indicates that the positive electrode material is copper (Cu) or a member containing copper. "5Mg", "5Mn", and "5Na" each indicate that the positive electrode material is magnesium (Mg), manganese (Mn), sodium (Na), or a member containing these metals.

Each of the positive electrode materials 5Cu, 5Mg, 5Mn, and 5Na is one positive electrode 5. For this reason, these symbols will also be used as the symbols for the positive electrode 5. "5X" will be used as a code indicating one or more arbitrary positive electrode materials or a positive electrode in which the positive electrode materials are used.

The positive electrode 5 using such a positive electrode material 5X is arranged together with the negative electrode 6 so as to face, for example, the inside of the flow path 30 through which circulating water flows. As a result, when a current flows between each positive electrode material 5X and the negative electrode 6 via circulating water, metal ions corresponding to the positive electrode material 5X are generated as cations in each positive electrode material 5X. It turns out. For example, in the positive electrode material 5Cu, when a current flows, copper that has lost its negative charge is dissolved in the circulating water as copper ions (Cu ²⁺ ). From this, the type of cation to be dissolved in the circulating water can be selected by selecting the positive electrode material 5X.

Each of the positive electrode materials 5X is connected to the positive connection terminal 15 via a connection portion including, for example, wiring, the variable resistor 17, and wiring. Although only four connection parts are shown in FIG. 2, the number is not particularly limited. In other words, since the connecting portions allow current to flow through the connected positive electrode materials 5X, the number thereof may be matched to the number of types or types of positive electrode materials 5X to be employed.

The variable resistor 17 included in each connection portion makes it possible to adjust the amount of current flowing through the connected positive electrode material 5X. Therefore, in this embodiment, the amount of each cation generated can be managed (controlled) by adjusting the resistance value of the variable resistor 17. When the current can be turned on and off, the cations to be generated can be selected. For this reason, a variable resistor 17 that can turn on/off the current may be used, or a switch or the like that can turn on/off the current may be included in the connection part. Furthermore, an ammeter may be included in each connection so that the amount of cations generated can be managed with higher precision.

It is known that the copper, magnesium, manganese, and sodium cations contained in each positive electrode material 5X have the following roles in the human body.
Copper binds to the active centers of about 10 types of enzymes and plays various functions in living organisms. It is an essential mineral for preventing anemia, and is a component of the enzyme cytochrome C oxidase, which is involved in the energy metabolism of immune cells such as macrophages. Therefore, it has the effect of increasing immunity and preventing arteriosclerosis. It is also involved in energy production, iron metabolism, active oxygen removal, extracellular matrix maturation, and neurotransmitter production.

Magnesium is involved in energy production, nucleic acid and protein maintenance, body temperature regulation, nerve excitation, muscle contraction, and hormone secretion. Promotes metabolism as a catalyst.
Manganese is a mineral required to activate bone and liver enzyme activity. In addition to being a component of some enzymes, even enzymes that do not contain manganese are often required for activation. It is also important in lipid and carbohydrate metabolism.

Sodium is a mineral necessary for regulating the balance of body fluids inside and outside cells, or osmotic pressure. It is also greatly involved in muscle contraction, nerve transmission, etc.
A cation-containing microbubble generator not only makes these minerals ingestible as cations, but also stabilizes the microbubbles with the cations, making the benefits of the microbubbles more accessible. To make it easier to utilize the advantages of microbubbles while also making it possible to utilize the advantages depending on the cations contained. For this reason, it is possible to provide a liquid that can be more widely used and more useful in a wide variety of fields such as environmental purification, food, medicine, and health. This liquid, that is, water, can be widely used for improving water quality in rice fields, ponds, lakes, etc., improving soil in fields, improving the growing environment for plants, etc.

Note that the cations to be contained in the liquid (circulating water) are not limited to those mentioned above. It is desirable to determine the type of cation to be included, the amount of the cation, etc. depending on the person who will ingest it, the condition of the land to be improved, the condition of the growing environment, etc. The metal ion generator 2 is useful in producing a desired liquid because it can not only individually generate determined cations but also adjust the amount of the cations generated.

In this embodiment, one positive electrode 5 is manufactured using multiple types of positive electrode materials 5X, but as shown in FIG. , 5Na may be arranged facing each other. In this case, the effective area of the positive electrodes 5Cu, 5Mg, 5Mn, and 5Na can be made larger. Further, the same positive electrode material 5X can be used as a plurality of positive electrodes 5. For this reason, there is an advantage that the range of adjustment of the cations to be included, the amount of each cation generated, etc. can be made wider.

The positional relationship of the metal ion generator 2, the microbubble generator 3, and the overflow pump 4 that constitute the cation-containing microbubble generator is not limited to that shown in FIG. 1. As long as the flow of circulating liquid water can be ensured, the positional relationship between them can be modified in various ways. For this reason, as shown in FIG. 4, for example, the circulating water from the water facility 1 is circulated back to the water facility 1 via the micro bubble generator 3, the excess flow pump 4, and the metal ion generator 2. Also good.

FIG. 5 is a diagram illustrating an example of a positive electrode and a negative electrode employed in a metal ion generator that constitutes a cation-containing microbubble generator according to another embodiment of the present invention. FIG. 6 is an explanatory diagram showing a configuration example of a positive electrode and a negative electrode employed in a metal ion generator that constitutes a cation-containing microbubble generator according to another embodiment of the present invention. FIG. 6 particularly shows an example of the configuration of the positive electrode 5 in a top view.

As shown in FIG. 5, the positive electrode 5 is manufactured as a cylindrical structure 50 as a whole, and the negative electrode 6 is manufactured into a rod shape. The rod-shaped negative electrode 6 is arranged so that its axial direction coincides with or almost coincides with the radial center of the structure 50 or approximately with the center.

A water inlet 51 is provided at the lower part, which is one end of the structure 50, for letting the circulating water flow into the inside, and a water inlet 51 is provided at the upper part, which is the other end of the structure 50, for discharging the circulating water that has flowed into the inside. A discharge port 52 is provided. Thereby, the circulating water that has flowed into the structure 50 from the water inlet 51 flows upward along the inner surface of the structure 50 with the negative electrode 6 as the center, as shown by the arrow in FIG. It becomes a spiral flow and flows out from the discharge port 52. In this way, since the circulating water existing between the negative electrode 6 and the structure 50 flows throughout, cations can be efficiently generated.

As shown in FIG. 6, the structure 50 is formed into a cylindrical shape using four types of electrically insulated positive electrode materials 5Cu, 5Mg, 5Mn, and 5Na. The four types of positive electrode materials 5Cu, 5Mg, 5Mn, and 5Na all form a pair and are arranged at point-symmetrical positions with the axis of the structure 50 as the center. Each of the pair of positive electrode materials 5Cu, 5Mg, 5Mn, and 5Na is connected to the positive connection terminal 15 via a connection portion. In FIG. 6, for convenience, only one of the positive electrode materials 5Cu, 5Mg, 5Mn, and 5Na is connected to the positive connection terminal 15 via the connection portion.

In the case of such a structure 50, the distances between each of the positive electrode materials 5Cu, 5Mg, 5Mn, and 5Na and the negative electrode 6 can all be matched within a narrow range. Therefore, the amount of each cation generated can be controlled more easily.

Note that in this other embodiment, there are four types of positive electrode materials 5X constituting the structure 50, but the number of types is not particularly limited. In addition, if there is a cation that should be generated in a larger amount than others, the positive electrode material 5X for generating the cation is placed between the structure 50 and the negative electrode 6 in the radial direction of the structure 50. It may be placed between the two. The closer the distance to the negative electrode 6 is, the larger the amount of current flowing becomes, so more cations can be generated. The positive electrode material 5Ca indicated by a broken line in FIG. 6 is an example of the positive electrode material 5X, and represents an example of its arrangement.
