Air supply device of nano bubble generation system

The present invention relates to an air supply device capable of selectively adjusting and supplying an amount of air to a bubble generating space in a nanobubble generating system configured to generate nanobubbles, which are microbubbles having microscopic diameters, by dissolving air in raw water. .

Specifically, it is designed to suck and supply external air through the supply pressure (water supply pressure) of raw water supplied to the bubble generating space through the raw water pipe, so that the amount of air supplied is selectively controlled by the user, so that the nano It relates to an air supply device for a nano bubble generating system designed to maximize bubble generating efficiency.

In general, nanobubbles are ultra-fine air bubbles that cannot be seen with the naked eye, and are fine air particles with a size of 1/2,000 of normal bubbles and pores of the skin of 25㎛ or less. It generates high sound pressure of 140db, and 3) instantaneous high heat of 4,000 to 6,000 degrees is generated.

In other words, normal bubbles rise in water and rupture on the surface, but nanobubbles are contracted by pressure in water and generate various energies and disappear.

These nanobubbles are microscopic bubbles that are mainly generated when water and air are vigorously rotated.

Such nanobubbles are used in various fields due to their physical and chemical properties such as "gas dissolution effect, self-pressurization effect, and electrification effect", and recently they are used in various aquaculture and hydroponic cultivation, especially in the fields of fishery and agriculture, In the medical field, it is used for precise diagnosis, and it is used in physical therapy, high-purity water treatment, and environmental devices in various fields.

In other words, it is widely used from hot spring bath to cancer diagnosis, and it is known that it regenerates skin and has excellent sterilization effect.

The nanobubbles as described above are generated in various ways such as a swirling liquid flow method, a state mixer method, an ejector method, a venturi method, a pressure dissolution method, an ultrasonic method, an electrolysis method, and a micropore filter method.

In order to generate nanobubbles through these various nanobubble generating facilities or devices, a gas-mixed liquid (supply water) is supplied and the gas is converted into microbubbles to generate nanobubbles.

In the above, the process of converting the supply water into microbubbles is performed through a process in which the supply water containing bubbles (a mixture of water and air) is separated and compressed while passing through the microtube passage of the generating unit equipped with the microtube passage.

As one of the nanobubble generators that generate nanobubbles as described above, there is Korean Patent Registration No. 10-1146040 (name: nanobubble generator), and the nanobubble generator, as described in the publication, A bubble generating chamber equipped with a water inlet through which water flows in, an air inlet through which air flows in, and a discharge hole through which air is discharged, provided between the water inlet, air inlet, and discharge of the bubble generating chamber, and rotated by being inserted into the shaft of the motor, and the water inlet And a rotating disk provided with a plurality of induction holes through which water introduced through the air inlet is guided, provided to be in close contact with the moving direction of the water and air of the rotating disk, and branching the water and air induced through the induction holes outwardly It consists of a fixed disk equipped with a plurality of stirring pieces protruding in the direction of the rotating disk so as to stir water and air according to the rotation of the rotating disk at the same time.

Accordingly, since the water and air are rubbed while rubbing with the agitating pieces and rubbing while passing between the agitating pieces in a jig jack, the water and air are strongly agitated and compressed at the same time as being crushed.

This impact-type microbubble generator not only requires a high pressure of 5 to 20 bar, but also has a large flow loss, requires a large number of nozzles and a bulky mixing tank, so the structure and equipment of the device are complicated. .

On the other hand, the swirling liquid flow type microbubble generator, like the impact nozzle type, generates nanobubbles through the transfer pressure introduced in the process of transferring the mixed water of water and air through the space in a spiral shape. It is designed to generate nanobubbles by the vortex pressure generated while the mixed water is transported while forming a vortex by forming a spiral conduit.

However, such a swirling liquid flow type microbubble generator does not generate microbubbles through a single nozzle and requires a high pressure as well as a bulky mixing tank.

Recently, a nano-bubble generation system capable of generating nano-bubbles by dissolving air contained in a mixed water of water and air supplied from the outside through a dissolving means having a dissolving space to form an air-dissolving pressure therein. This is currently being proposed.

That is, as the air pressure continuously increases in the dissolving space) according to the supply of the mixing water, the dissolving pressure that dissolves the air remaining in the dissolving space is generated.

Therefore, in the dissolving space, nanobubble water is smoothly formed according to the generation of mixed water according to the mixing of raw water (tap water) and air and the dissolution of the air contained in the mixed water.

In Korea Patent Registration No. 10-2105794 (name: nano bubble generator), as described in the publication, it has a supply port through which mixed water having a transfer pressure is supplied and a discharge port through which the mixed water is discharged to the outside, and a gap between the supply port and the discharge port is provided. A nanobubble generating device comprising: a dissolving means sealed against the outside and equipped with a dissolving space configured to form a dissolving pressure of gas against water; In the dissolving means, in a state where the inlet of the supply port is disposed on the outer surface, the outlet of the supply port is disposed on the upper surface so that the supply pipe through which the mixed water is supplied from the outside is connected to discharge to the upper surface, and the inlet of the discharge port is on the upper surface. Dissolving bodies discharged to the outside by being connected to a discharge pipe through which the mixed water is discharged from the outside with the outlet of the discharge port disposed on the outer surface in the arranged state; A dissolving container having a dissolving space having a dissolving space so as to form a dissolving pressure with respect to the mixed water supplied through the outlet of the supply port; ; At the outlet of the supply port on the upper surface of the dissolving body, the injection pipe has a vertical length and has a transfer pipe through which the mixed water is transported, and sprays the mixed water to the upper surface of the dissolving container to apply collision pressure. A nanobubble generating device equipped with a binding tube to be bound is described.

Embodiments of the present invention may be modified in various forms, and the scope of the present invention should not be construed as being limited to the examples described in detail below. This embodiment is provided to more completely explain the present invention to those skilled in the art. Therefore, the shapes of elements in the drawings may be exaggerated to emphasize a clearer explanation. It should be noted that in each drawing, the same members are sometimes indicated by the same reference numerals. Detailed descriptions of well-known functions and configurations that may unnecessarily obscure the subject matter of the present invention are omitted.

1 to 8 are views showing the air supply device 1 of the nano bubble generating system according to an embodiment of the present invention, and the air supply device 1 of the nano bubble generating system 10 according to the present embodiment. ) is a nanobubble generating system 10 designed to dissolve air in raw water to generate nanobubbles, which are fine bubbles having a minute diameter, by dissolving air contained in mixed water in raw water to generate nanobubbles. It is particularly applied to supply by selectively adjusting the supply amount of air to the bubble generating space (A).

That is, according to the difference in the supply pressure (water supply pressure) of the raw water in the nanobubble generating environment, the appropriate air supply amount is adjusted according to the difference, so that the quality of use is improved.

The raw water pipe 100 for supplying raw water in the nanobubble generating system 10 is provided with a supply pump 300 for forcibly pumping and supplying the raw water, so that the dissolving pressure in the bubble generating space (A) is reduced. It can be formed appropriately, and it is preferable to be suitably applied according to the user's choice.

The air supply device 1 of the nano bubble generating system 10 according to this embodiment includes a raw water pipe 100 to supply raw water having a transfer pressure, and raw water supplied from the raw water pipe 100 flows in. and is applied to the nanobubble generating system 10 having a bubble generating means 200 equipped with a bubble generating space A to generate nanobubbles therein.

That is, it is spatially connected to the movement path of the raw water of the raw water pipe 100 and the bubble generating means 200 to supply air from the outside, and is connected to an unshown raw water supply facility (including water supply equipment) to supply raw water Through the raw water pipe 100 to which (including tap water) is supplied, raw water having a transfer pressure generated by the raw water supply facility is supplied to the bubble generating space A according to the user's selection.

At this time, as the water pressure in the bubble generating space (A) is continuously increased according to the continuous supply of the mixing water, dissolving pressure for air is generated by the high pressure water pressure in the bubble generating space (A).

Accordingly, in the bubble generation space (A), nanobubble water is smoothly formed according to the generation of mixed water according to the mixing of raw water and air and the dissolution of the air contained in the mixed water.

In the above, the raw water pipe 100 may be composed of a 'water supply pipe' connected to the water pipe or/and a 'water valve' connected to the water supply pipe; It may consist of a 'water supply pipe' connected to a separate water supply device such as a 'water purification device' or/and a 'water valve' connected to the water supply pipe, and is preferably applied suitably according to the user's selection.

The air supply device 1 of the nano-bubble generating system 10 according to this embodiment made in this way is air spatially connected to the movement path of the raw water between the raw water pipe 100 and the bubble generating means 200. a supply pipe (3); an air inlet pipe 4 that is spatially connected to the air supply pipe 3 and through which external air is introduced; It is provided on the air movement path between the air supply pipe 3 and the air inlet pipe 4 to selectively adjust the spatial area of the air movement passage and is supplied per unit time to the air supply pipe 3 a control solenoid valve 5 to selectively control the amount of air; an air pressure detection sensor 6 provided on an air movement path between the air supply pipe 3 and the control solenoid valve 5 to detect air supply pressure; It is controlled by receiving power from the power supply unit 71, calculates the sensing data held through the air pressure sensor 6, adjusts the control solenoid valve 5, and supplies per unit time to the air supply pipe 3 A control means (7) configured to adjust the amount of air;

That is, through the supply pressure (water supply pressure) of the raw water supplied to the bubble generating space (A) through the raw water pipe 100, external air is sucked through the air supply pipe 3 to mix water and air. Mixed water is supplied to the bubble generating space (A) to generate nanobubbles.

At this time, the detected data sensed through the air pressure sensor 6 is received, calculated based on the data set in the control means 7, and the control solenoid valve 5 is electrically driven according to the calculated data. By controlling the amount of air supplied to the bubble generating space (A), the nanobubble generating efficiency is maximized.

On the other hand, the air supply device 1 of the nano bubble generating system 10 according to this embodiment is electrically connected to the control means 7 and is configured to selectively control the amount of air supplied to the air supply pipe 3.

That is, in accordance with the air supply amount selected by the user through the control switch 72, the error due to the difference in the supply pressure (water supply pressure) of the raw water in the use environment is adjusted to the air supply detected through the air pressure sensor 6. By detecting the scent, the detected data is transmitted to the control means 7 in real time, and the control means 7 adjusts to the air supply amount selected through the control switch in real time through the control electronic valve 5. By supplying an appropriate amount of air supply, the quality of use is improved.

Accordingly, while external air is sucked through the air supply pipe 3, it is supplied to the inside, mixed with raw water, and supplied to the bubble generating means 200.

Therefore, air consumed when nanobubbles are generated in the bubble generating space (A) can be stably supplied without a separate air supplier; In particular, economic benefits and space usage efficiency are maximized through structural simplification.

In the above, the space in which the vacuum suction pressure is formed in the movement path of the raw water pipe 100 and the bubble generating means 200 may be formed at a portion having a shape in which the diameter is reduced or enlarged on the movement path, According to 'Pascal's principle' and 'Bernoulli's theorem', 'cavity lines (cavitation)' can be generated in a space with a shrinking diameter.

That is, as the vacuum suction pressure is naturally formed during the movement of the raw water, a vacuum suction force to the air supply pipe 3 is generated, so that external air can be supplied naturally.

At this time, according to the moving pressure of the air generated inside the sensor tube 61, the floating body 62 floats while changing its position according to the amount of air intake inside the sensor tube 61, The sensing element 63 senses the floating position of the floating body 62 and transmits it to the control means 7 .

Accordingly, after calculating based on the sensed data transmitted from the control unit 7, the control electronic valve 5 is adjusted so that the air pressure selected through the control switch 72 is electrically operated so as to be supplied.

Therefore, the quality of use is improved by supplying an appropriate air supply amount while adjusting the error according to the difference in the supply pressure (water supply pressure) of raw water in the use environment.

In the above, the sensor pipe 61 may be provided with a 'seeing window' that allows the user to see the inside with the naked eye from the outside to recognize the position of the floating body 62, which is suitably applied according to the user's selection. it is desirable

That is, in a state in which the user recognizes the position of the floating body 62 while looking through the viewing window, the user recognizes the floating position of the floating body 5 through the air supply pressure controlled through the control solenoid valve 5. will do

In the above sensor pipe 61, 'display scales' to schematically recognize the position of the floating body 62 can be engraved so that the recognition of information can be made more clear.

Depending on the presence or absence, a one-way check valve 8 configured to open and close the supply of air may be provided.

That is, when the raw water is supplied from the raw water pipe 100, when a vacuum pressure is formed by the moving pressure of the raw water, the one-way check valve 8 is opened and external air is supplied via the air supply pipe 3. After being mixed with raw water, it is supplied to the bubble generating space (A) of the bubble generating means (200).

In addition, according to the user's selection, when the supply of raw water from the raw water pipe 100 is stopped, the vacuum pressure is released in the movement path of the raw water, and in the bubble generating space (A) of the bubble generating means 200 As the one-way check valve 8 is closed by the reverse flow of mixed water, leakage to the outside is not generated.
