Description

Nano-bubble generator {Nano-bubble generator}

The present invention relates to a nanobubble generator configured to generate nanobubbles, which are microbubbles having a nano unit in diameter by dissolving air contained in mixed water, and more particularly, to a raw water pipe through which water is supplied (water pipe ) Is connected to the raw water valve (water valve) to open and close, and receives raw water according to the opening and closing operation of the raw water valve, and seals against the outside through the supplied raw water. According to the increase, it is dissolved in raw water to become nano, thereby generating nanobubbles, and when not in use, external air is supplied to fill the air, so that stable air dissolution occurs when nanobubbles are generated. .

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 pores on the skin. 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 their 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 in various aquaculture and hydroponics. 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, 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 nanobubbles 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 (supplied water) mixed with gas 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 carried out through the process of separating and compressing the feed water containing bubbles (a mixture of water and air) 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 equipped with a water inlet through which water flows in, an air inlet through which air flows in, and a discharge port through which air flows in, and between the water inlet and the air inlet and the discharge port of the bubble generation chamber, rotated by being inserted into the shaft of a motor, and a water inlet 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, 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 to stir water and air according to the rotation of the rotating disk at the same time.

Accordingly, water and air are stirred while being rubbed against the agitating pieces, as well as friction while passing through the jig jack between the agitating pieces, so that water and air are strongly agitated and compressed at the same time as if crushed.

This impact-type microbubble generator requires a high pressure of 5 to 20 bar, as well as a large flow loss, and a large number of nozzles and bulky mixing tanks are required, 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 transfer pressure introduced in the process of transferring 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 such a rotating liquid holding method has a problem that it cannot generate micro-bubbles through a single nozzle, and requires a high pressure as well as a bulky mixing tank.

' 형상을 가지는 용해통(3);을 더 가진다.In the nanobubble generator 1 according to the present embodiment made as described above, the dissolving means is assembled while the lower part is opened and the open lower part is bound to the upper part of the dissolution body 2 to form the dissolution space (A). And the cross-sectional shape

'Has a melting vessel (3);

That is, the raw water supplied through the supply port 21 of the dissolution body 2 collides with the inner circumferential surface of the dissolution container 3, and is formed through the combination of the dissolution body 2 and the container 3 As the air remaining in the dissolution space (A) is dissolved in raw water through the dissolution pressure formed in the dissolution space (A) in the process of being supplied to the dissolution space (A) and being moved to the discharge port 22, , After generating the nano-bubble water, it is discharged to a separate discharge pipe 13 through the discharge port 22 and supplied to a use place not shown.

On the other hand, in the nanobubble generator 1 according to the present embodiment, in the dissolution body 2, in the discharge port 22, as shown in FIG. 4, a'tube body' having a'pipe' shape. One end of the'connector 13' made of'is pipe-connected so that it is spatially connected; At the other end of the connecting pipe 13, the supply port 21 of the dissolving body 2 is connected so that it is spatially connected; The supplied mixed water may be nanobubbled while passing through each of the pair of dissolution spaces A connected in series with each other, thereby improving nanobubble generation efficiency and nanobubble quality.

In the nanobubble generating device 1 according to the present embodiment made as described above, the outlet of the supply port 21 from the upper surface of the melting body 2 has a vertical length and the mixed water is transferred therein. A binding pipe 23 to which the injection pipe 4, which has a pipe and sprays the mixed water to the upper surface of the melting vessel 3 to apply a collision pressure, may be provided.

That is, the mixed water supplied to the melting space (A) through the supply port 21 is supplied to the melting space (A) via the injection pipe (4) bound to the binding pipe (23).

At this time, the mixed water is sprayed by the injection pipe 4 and collides with the upper inner circumferential surface of the melting vessel 3 forming the melting space A, and is applied with a collision pressure to form nanobubbles.

Accordingly, as the position where the raw water is supplied in the melting space (A) is disposed at a position higher than the outlet of the discharge port 22, the inside of the discharge port 22 forms a vacuum state by the raw water from the outside. While preventing unauthorized air from being supplied, airtightness of the melting space A is formed, thereby forming a melting pressure by increasing air pressure according to the continuous supply of raw water.

In the inside of the binding pipe 23, the nut pipe 5, which is screwed with the lower end of the injection pipe, is spatially connected and coupled to facilitate the assembly of the melting body 2 and the injection pipe 4 Can be done.

As it is drained, the air density in the melting space (A) decreases, thereby forming a low pressure air pressure.

At this time, the pneumatic check valve 6 is opened according to the low-pressure air pressure formed in the melting space (A) and external air is introduced.

Accordingly, when the raw water valve 11 is intermittently operated by supplying air to the melting space (A), even if there is no forced supply of air through a separate facility and device to the melting space (A). , Later, as the air required for the nanobubble generation process remains sufficiently in the melting space (A), the generation of nanobubbles is made stably. The efficiency of use is improved through structural simplification and miniaturization.

The operational effects of the nanobubble generating device 1 according to the present embodiment made as described above will be described in detail as follows.

The nanobubble generating device 1 according to the present embodiment, according to the selective intermittent operation of the raw water valve 11 by the user with respect to the raw water supplied from the raw water pipe 10, the raw water valve 11 Raw water is selectively supplied to the connected supply port 21.

On the other hand, according to the selective intermittent operation of the raw water valve 11 by the user, in a state in which the supply of raw water to the melting space (A) is stopped, the pneumatic check valve 6 is, the melting space (A) It is opened according to the low-pressure air pressure formed in and external air is introduced, so that air remains in the melting space (A).

The nano-bubble generating device 1 according to this embodiment, according to the selective operation of the raw water valve 11 by the user, passes the supply port 21 to the dissolution space (A) When supplied, raw water is injected by the injection pipe 4 while being supplied to the melting space A via the injection pipe 4 bound to the binding pipe 23, as well as the melting space A The collision pressure is applied while colliding with the upper inner circumferential surface of the melting vessel 3 forming a.

At this time, as the dissolution space (A) forms a dissolution pressure due to the increased air pressure according to the continuous supply of raw water, the pneumatic check valve 6 is closed and the inflow of external air is stopped, and the dissolution space After the air is dissolved in (A) and converted into nanobubbles, it is supplied to a use place (not shown) through the discharge port 22 through the discharge pipe 12 and used.
