Description

Nano Bubble Generator {Nano Bubble Generator}

The present invention relates to a nanobubble generator that generates nanobubbles, which are microbubbles, and more particularly, while the mixed water in which water (raw water) and air are mixed is transferred, the gas contained while passing through the dissolution space is water (raw water ) To generate nanobubble water as it dissolves into nanoparticles, and in particular, when nanobubble water is not used, the supply of air is essentially stopped and the driving state is initialized to improve the use efficiency when reused. It relates to a nano-bubble generating device.

In general, nanobubbles are ultra-fine bubbles that cannot be seen by the eye, and are microscopic air particles with a size of 1/2,000 of a normal bubble and less than 25 μm of skin pores. When extinct, 1) 40KHz of ultrasonic waves are generated, and 2) It generates a high sound pressure of 140db, and 3) instantaneous high heat of 4,000 to 6,000 degrees is generated.

In other words, general bubbles rise in water and rupture at the surface, but nanobubbles shrink by pressure in the water and dissipate by generating various energy.

These nanobubbles are mainly generated when water and air are violently rotated with ultra-fine bubbles.

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

In other words, the field of use is widely ranging from hot spring baths to cancer diagnosis, and it is known that it regenerates the skin and has excellent sterilization effects.

The nano-bubbles as described above are generated in a variety of ways, such as a rotating liquid retention type, a state mixer type, an ejector type, a Venturi type, a pressure melting type, an ultrasonic type, an electrolysis type, and a microporous filter type.

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

In the above, the process of converting the feed water into microbubbles is performed through a process in which the feed water containing bubbles (a mixture of water and air) is separated and compressed while passing through the micropipes of the generating means provided with the micropipes.

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 generation chamber having a water inlet through which water flows in, an air inlet through which air flows in, and an outlet through which air is discharged, and a water inlet provided between the water inlet and the air inlet and the discharge port of the bubble generation chamber and rotated by being inserted into the shaft of the motor And a rotating disk provided with a plurality of guide holes through which the water introduced through the air inlet is guided, and the rotating disk is provided to be in close contact with the moving direction of water and air of the rotating disk, and the water and air guided through the guide hole are branched outward. It consists of a fixed disk provided 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, water and air are agitated while being rubbed against the agitating pieces, as well as friction while passing through the jig jack between the agitating pieces, so that the water and air are strongly agitated and compressed at the same time as if crushed.

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

On the other hand, the microbubble generating device of the rotating liquid holding method generates nanobubbles through the conveying pressure introduced in the process of conveying the mixed water mixed with water and air through the space in a vortex, like the impact nozzle method. By forming a vortex type pipe, nanobubbles are generated by the vortex pressure generated while the mixed water is transferred while forming a vortex.

However, the apparatus for generating micro-bubbles of this orbiting liquid holding method has a problem in that it cannot generate micro-bubbles through a single nozzle, and requires a high pressure as well as a bulky mixing tank.

In recent years, a dissolving means provided with a dissolving space to form a dissolving pressure of air inside; a nano-bubble generation system that dissolves the air contained in the mixed water of water and air supplied from the outside through a nano-bubble generation system. This is the situation being proposed.

That is, as the air pressure in the melting space) increases continuously due to the supply of mixed water, a dissolution pressure at which dissolution of the air remaining in the dissolution space occurs is generated.

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

First, as shown in Fig. 5, in the applied state to implement the supply of raw water through the raw water valve 10 provided in the raw water pipe 2, when not driven, the raw water is closed to the raw water valve 10 side. The transfer pressure of ('6 bar' in the case of tap water) is formed, and the water pressure is not formed on the raw water pipe 2, the dissolution tank 7 and the drain pipe 8.

And when driven, through the feed pressure of the raw water ('6 bar' in the case of tap water) formed in the open raw water valve 10, to the raw water pipe 2, the dissolution tank 7 and the drain pipe 8 The feed pressure of the raw water (approximately 4 bar, depending on the decompression caused by the drainage of the raw water) is formed.

At this time, in the input pressure switch 91, a set pressure value for cutting off the power supply to the control means 4 is applied to the feed pressure of the raw water in the raw water pipe 2 (depressurization due to the drainage of the raw water). Accordingly, by setting a value of 3.5 to 4.5 bar based on approximately 4 bar); By maintaining the power supply of the power supply unit 3 to the control means 4, the operating state of the air compressor 5 is maintained.

In addition, when the use of bubbled water is completed and the raw water valve 10 is not driven through the closure, the water pressure is not formed on the raw water pipe 2, the dissolution tank 7 and the drain pipe 8, so that the input Is lowered below the set pressure value (3.5 ~ 4.5 ba) of the pressure switch 91; This is sensed through the input pressure switch 91 to cut off the power supply of the power supply unit 3 to the control means 4 to implement initialization through reset for the entire drive.

On the other hand, as shown in Figure 6, in the applied state to implement the drainage of raw water through the drain valve 11 provided in the drain pipe 8, when not driven, the closed 1o water valve 11 side The feed pressure of raw water ('6 bar' in the case of tap water) is formed, and on the raw water pipe 2, the dissolution tank 7 and the drain pipe 8, the feed pressure of raw water ('6 bar' in the case of tap water) Is formed.

And when driven, through the feed pressure of the raw water ('6 bar' in the case of tap water) formed in the opened drain valve 11, to the raw water pipe 2, the dissolution tank 7 and the drain pipe 8 The feed pressure of the raw water (approximately 4 bar, depending on the decompression caused by the drainage of the raw water) is formed.

At this time, in the output pressure switch 92, the set pressure value for cutting off the power supply to the control means 4 is the transfer pressure of the raw water in the drain pipe 2 (according to the decompression by the drainage of the raw water) , About 4bar) by setting a value of 3.5 to 4.5 bar; By maintaining the power supply of the power supply unit 3 to the control means 4, the operating state of the air compressor 5 is maintained.

In addition, when the use of the bubbled water is completed and the drain valve 11 is not driven through the closure, the raw water pipe 2, the dissolution tank 7 and the drain pipe 8, the transfer pressure of the raw water (tap water In the case '6bar') is formed; At this time, it becomes higher than the set pressure value (3.5 ~ 4.5 ba) of the output pressure switch 92; This is sensed through the output pressure switch 92 to cut off the power supply of the power supply unit 3 to the control means 4 to implement initialization through reset for the entire drive.

As another application example of the nanobubble generator 1 according to the present embodiment made as described above, when the input pressure switch 91 and the output pressure switch 92 are simultaneously provided and applied, the input pressure switch (91) and the set pressure values of the output pressure switches 92 are formed to be the same, respectively, and the control means 4, the air compressor 5, the input pressure switch 91, and the output pressure switch ( The electrical connections of 92) are configured in series, and the power supply to the control means 4 independently of each other according to the pressure values sensed by the input pressure switch 91 and the output pressure switch 92, respectively. It is possible to implement initialization through reset for the entire operation by cutting off the power supply of (3); It is desirable to apply it according to the user's choice.

That is, in an applied state in which the supply of raw water is implemented through the raw water valve 10 provided in the raw water pipe 2, the input pressure switch 91 and the output pressure switch 92 include the control means 4 The set pressure value that cuts off the power supply to) is set to a value of 3.5 to 4.5 bar based on the feed pressure of the raw water in the raw water pipe 2 (approximately 4 bar according to the decompression by the drainage of the raw water). ; When not driven through the closing of the raw water valve 10, one of the input pressure switch 91 and the output pressure switch 92 detects a state that decreases below a set pressure value (3.5 ~ 4.5 ba). In this case, the power supply of the power supply unit 3 to the control means 4 may be independently cut off to implement initialization through a reset for the entire operation.

In addition, in the applied state to implement the drainage of the bubble water through the drain valve 11 provided in the drain pipe 8, the input pressure switch 91 and the output pressure switch 92, the control means ( 4) Set a value of 3.5 to 4.5 bar based on the transfer pressure of bubbled water in the drain pipe 8 (approximately 4 bar, depending on the decompression caused by the drainage of raw water). So; When not driven through the closing of the drain valve 11, when detecting a state higher than the set pressure value (3.5 ~ 4.5 ba) in one of the input pressure switch 91 and the output pressure switch 92 , Independently shutting off the power supply of the power supply unit 3 to the control means 4 may be implemented to implement initialization through a reset for the entire operation.
