Description

Assembly-type nano bubble generator {Assembly-type nano bubble generator}

The present invention relates to a prefabricated nanobubble generating device configured to generate nanobubbles, which are microbubbles, by dissolving air contained in mixed water.

Specifically, in the process of transporting mixed water in which water and air are mixed passing through a dissolving space closed to the outside, gas contained therein is dissolved to form nanobubbles, and in particular, use efficiency can be improved through miniaturization. It relates to a prefabricated nanobubble generating device.

More specifically, a prefabricated nanobubble generator that is structurally simple and easy to separate and assemble to increase economic benefits through productivity improvement, as well as to maximize use efficiency by selectively forming multi-stage melting spaces. It is about.

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.

Accordingly, in recent years, nanobubble generators having various structures in which gas contained in a mixture of water and air is transported while passing through a dissolution space closed to the outside is dissolved to generate nanobubbles. is being proposed to

As one of them, there is Korean Patent Application No. 10-2019-0100676 (name: nano bubble generator), and as described in the publication, it is connected to a raw water valve to open and close the supply of raw water having a transfer pressure, and the raw water A nanobubble generator comprising: a dissolving means provided with a dissolving space configured to receive raw water as the valve opens and closes and to form a dissolving pressure of remaining air by the raw water supplied therein; The dissolving means is provided with a supply port connected to the raw water valve to supply raw water supplied to the dissolving space and a discharge port configured to drain the raw water filled in the dissolving space to the outside, and the inlet of the supply port is an outer surface.
