Description

Nano Bubble Generator

The present invention relates to a nano-bubble generator for generating nano-bubbles, which are microbubbles having a nano-unit in diameter, and more particularly, to a plurality of nano-bubble generators arranged in series while a mixed water in which water (raw water) and air are mixed is transferred. As the contained gas is dissolved in water (raw water) and formed into microbubbles while passing through the melting space of Of course, it relates to a nano-bubble generator to improve the nano-bubble generation efficiency by stably maintaining the amount of air required when nano-bubbles are generated by sharing the air pressure formed inside the plurality of dissolution spaces.

In general, nanobubbles are ultra-fine bubbles that cannot be seen with the naked eye. They are microscopic air particles less than 25㎛ in pores of the skin with 1/2 the size 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 utilized 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 precise diagnosis, and in various fields, it is used for physical therapy, high-purity water treatment, and environmental devices.

In other words, it has a wide range of uses, from hot spring baths to cancer diagnosis, and is known to regenerate the skin as well as 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 in which the feed water is converted into microbubbles is made through a process in which the feedwater containing air bubbles (a mixture of water and air) is separated and compressed while passing through the microtubules of the generating means provided with the microtubules.

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 provided to be in close contact with the moving direction of water and air of the rotary disk, the water and air induced through the guide holes 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 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 spiral shape, 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, the 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.

Recently, a dissolution means provided with a dissolution space (A) configured to form a dissolution pressure of air inside; nano-bubbles are generated by dissolving air contained in a mixture of water and air supplied from the outside. A bubble generating system is being proposed.

That is, according to the continuous increase of the air pressure in the dissolution space (A) according to the supply of the mixed water, the dissolution pressure at which the 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 (tap water) and air in the dissolution space and the dissolution of air contained in the mixed water.
