Description

Nano-bubble generator

The present invention relates to a nanobubble generating device configured to dissolve air contained in mixed water to generate nanobubbles, which are microbubbles having a nanometer in diameter.

Specifically, in the process of transporting mixed water in which water and air are mixed with respect to the outside through a closed dissolution space, the gas contained therein is dissolved and nano-formed to generate nanobubbles, and in particular, mixed water in the dissolution space. It relates to a nano-bubble generating device that maximizes the nano-bubble generating efficiency by inducing the vortex to increase the shear pressure.

In general, nanobubbles are ultra-fine air bubbles that cannot be seen with the naked eye. They are microscopic air particles less than 25㎛ in pores of the skin with the size of 1/2000 of normal bubbles. 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, normal bubbles rise in water and burst on the surface, but nanobubbles are reduced by pressure in the water, generating various energy and disappearing.

These nanobubbles are microscopic bubbles that occur mainly when water and air are violently rotated.

Such nanobubbles are being used in various fields due to their physical and chemical properties such as "gas dissolution effect, self-pressurization effect, and electrification effect". In the medical field, it is used for precision diagnosis, and in various fields, it is used for physical therapy, high-purity water treatment, and environmental devices.

In other words, its use ranges from hot spring baths to cancer diagnosis, and it is known to regenerate the skin and to have an excellent sterilization effect.

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

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

The process of converting the feed water into microbubbles in the above is made through the process of separating and compressing the feedwater (a mixture of water and air) containing bubbles while passing through the microtubule of the generating means provided with the microtubule.

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 is, as described in the publication, A bubble generating chamber provided with a water inlet through which water is introduced, an air inlet through which air is introduced and an outlet through which air is discharged, is provided between the water inlet and the air inlet and the outlet of the bubble generating chamber and is rotated by being inserted into the shaft of the motor and rotated through the water inlet. and a rotating disk provided with a plurality of guide holes through which water introduced through the air inlet is guided, and a rotation disk provided to be in close contact with the movement direction of water and air of the rotary disk, and branch the water and air induced through the guide hole in an outward direction 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 not only stirred while rubbing with the stirring pieces, but also rubbed while passing between the stirring pieces with a jig jack, so that the water and air are strongly stirred and compressed at the same time as if crushed.

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

On the other hand, the swirling liquid flow type microbubble generator 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 type nozzle method. Nanobubbles are generated by the vortex pressure generated while the mixed water is transported while forming a vortex by forming a vortex-type pipe.

However, such a device for generating microbubbles of the swirling liquid flow method has a problem in that it cannot generate microbubbles through a single nozzle and requires a high pressure as well as a bulky mixing tank.
