Description

Nano bubble generation system {Nano bubble generation system}

The present invention relates to a nanobubble generating system configured to generate nanobubbles, which are microbubbles having microscopic units in diameter, through the dissolution pressure of air in raw water.

Specifically, it relates to a nanobubble generation system designed to improve the nanobubble generation efficiency by preventing the drop in nanobubble generation efficiency due to a decrease in water pressure when mixed water is drained from the dissolving space.

More specifically, it relates to a nanobubble generating system to improve usability as the structure can be miniaturized and nanobubbles can be generated using tap water as raw water in an ordinary household.

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 mixing water, the dissolving pressure for dissolving 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.
