Description

Nano bubble generator {A nano bubble generator}

The present invention relates to a nanobubble generator that dissolves air in raw water to generate nanobubbles, which are fine bubbles with a microscopic diameter.

Specifically, it relates to a nanobubble generator that improves nanobubble generation quality by stably supplying mixed water to a pump that pumps mixed water into the dissolution space to form supply pressure. .

More specifically, it relates to a nanobubble generator that suctions and mixes external air according to the transport pressure of raw water through pumping, thereby stably supplying air without a separate air supply device. .

More specifically, it relates to a nanobubble generator that improves the quality of nanobubble generation by allowing the user to selectively control the amount of external air flowing into raw water.

In general, nanobubbles are ultra-fine bubbles that cannot be seen with the eye. They are 1/2,000 the size of regular bubbles and are fine air particles in skin pores of 25㎛ or less. When they disappear, 1) they generate ultrasonic waves at 40KHz, and 2) It generates a high sound pressure of 140db, and 3) generates instantaneous high heat of 4,000 to 6,000 degrees.

In other words, normal bubbles rise in water and burst at the surface, but nanobubbles shrink under pressure under water and disappear while generating various types of energy.

These nanobubbles are ultra-fine bubbles that mainly occur when water and air are violently 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 in recent years, they have been used in various aquaculture and hydroponic cultivation, especially in the fishing and agricultural fields. , In the medical field, it is used for precise diagnosis, and is used in various fields such as physical therapy, high-purity water treatment, and environmental devices.

In other words, its field of use is wide ranging from hot spring bathing to cancer diagnosis, and it is known to regenerate the skin and also has an excellent sterilizing effect.

In order to generate nanobubbles through various nanobubble generating facilities or devices as described above, mixing water (feed water) containing gases is supplied and the gases are converted into fine bubbles to generate nanobubbles.

One of these nanobubble generators is Korean Patent Registration No. 10-1146040 (name: nanobubble generator), and as described in the publication, the nanobubble generator includes a water inlet through which water flows, and It is provided between a bubble generating chamber equipped with an air inlet through which air is introduced and an outlet through which air is discharged, a water inlet and an air inlet and an outlet of the bubble generating chamber, and is inserted into and rotated on the shaft of a motor and flows in through the water inlet and air inlet. A rotating disk is provided with a plurality of guide holes through which water is guided, and is provided to be in close contact with the moving direction of the water and air of the rotating disk. It diverges the water and air guided through the guide holes in an outward direction and at the same time, the rotating disk It consists of a fixed disk equipped with a number of stirring pieces protruding in the direction of the rotating disk to agitate water and air as it rotates.

Accordingly, the water and air are not only stirred by friction with the stirring pieces, but also are rubbed while passing between the stirring pieces in a jig jack, so that the water and air are strongly stirred and compressed as if crushed.

This impact-type microbubble generating device has the disadvantage of requiring a high pressure of 5 to 20 bar, large flow loss, and requiring multiple nozzles and a large mixing tank, making the structure and equipment of the device complicated.

On the other hand, the swirling liquid retention type microbubble generator generates nanobubbles through the inflowing transfer pressure in the process of transferring mixed water of water and air through the space in a spiral shape, like the impact nozzle type. It is designed to generate nanobubbles due to the eddy pressure generated while the mixed water is being transported while forming a vortex by forming a vortex-shaped pipe.

However, this swirling liquid retention type microbubble generating device has the problem of not being able to generate microbubbles through a single nozzle and not only requiring high pressure but also requiring a large mixing tank.

Recently, a nanobubble generating system is used to generate nanobubbles by dissolving the air contained in the mixed water of water and air supplied from the outside through a dissolving means provided with a dissolving space internally designed to create dissolution pressure of the air. This is being proposed.

In other words, as the air pressure in the dissolution space continues to increase due to the supply of mixed water, a dissolution pressure that causes dissolution of the air remaining in the dissolution space is generated.

Therefore, in the dissolution space, nanobubble water is smoothly formed by the generation of mixed water due to mixing of raw water (tap water) and air and the dissolution of air contained in the mixed water.

In Korean Patent Application No. 10-2019-0117140 (name: Nanobubble generator/2019.09.24.), as known in the gazette, a raw water pipe to receive raw water from the outside; an air compressor that is spatially connected to the raw water pipe and is supplied with power through control means for controlling the power of the power supply unit, compresses external air, pumps it, and supplies it; It is spatially connected to the raw water pipe and has a supply port through which mixed water having a conveying pressure is supplied and a discharge port discharging to the outside, and is sealed against the outside between the supply port and the discharge port to form a dissolution pressure of gas in water. A dissolution tank provided with space; A nanobubble generator is described, including a drain pipe spatially connected to the discharge port of the dissolution tank to drain nanobubble water generated inside the dissolution tank to the outside.
