Description

Nano-bubble generator

The present invention relates to a nano-bubble generating device capable of generating nano-bubbles, which are micro-bubbles, by dissolving air contained in mixed water. When not in use, when the supply of raw water is stopped, it is opened and supplied with external air to fill the consumed air when used later. It is about the generator.

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 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, 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.

In the nano-bubble generating device according to the present invention made as described above, when raw water is supplied to the dissolution space of the dissolving means to generate nano bubbles, the pressure (water pressure + air pressure) of the dissolution space is increased by the raw water supplied to the dissolution space. As it gradually increases and becomes larger than the external pressure of the dissolution space, the opening/closing space of the air supply means is closed to secure airtightness to the outside, preventing raw water from leaking to the outside, and preventing the dissolution pressure of the dissolution space from lowering. It has the effect of preventing the bubble generation efficiency from falling.

In addition, when the supply of raw water is selectively stopped due to the interruption of the nanobubble generation operation, the water pressure in the dissolution space drops and the total pressure in the dissolution space forms an equilibrium pressure with the external air pressure. As the air is filled into the dissolution space via the opening/closing space, it provides air to be consumed during later use, so that the nano-bubble-generating operation is smoothly performed.

In addition, it is possible to stably supply air without a separate and complicated air supply means, and thus it is possible to realize economic benefits through structural simplification and to maintain nanobubble quality.

In the above, each of the return spring 37 and the support spring 38 has the same elastic support force so that the opening and closing body 34 is not biased in any one direction of the supply hole 31 and the inlet hole 32 side. It is preferable to form a , but it is not limited thereto, and it is preferable to be selectively applied by the user.

In the supply end 36, the spacer protrusions 39 to separate the opening and closing body 34 from the inlet hole 32 when the opening and closing body 34 is in close contact may be protruded.

That is, the opening and closing body 34 may be prevented from closing the inlet hole 32 through the spacing protrusion 39 .

In the opening and closing body 34, the external pressure in the opening and closing space B and the internal pressure of the supply port 21 are released from a pressure equilibrium state, and the internal pressure of the supply port 21 is increased to increase the external pressure The supply hole 31 side while overcoming the elastic support force of the return spring 37 while the elastic force of the support spring 38 and the increased internal pressure of the supply port 21 are combined while having a greater pressure state direction to close the supply hole 31 .

That is, when an increase value (elastic support force of the return spring 37) set for the increase value of the internal pressure of the supply port 21 with respect to the external air pressure is formed, the supply hole 31 is closed.
