Description

Nano bubble generator for living water {Nano bubble generator}

The present invention relates to a nanobubble generating device for living water to increase the use efficiency by generating nanobubbles in the tap water supplied when using the domestic water, such as washing, washing, bathing, etc., in more detail, air in tap water The nanobubble generator for living water, which is able to obtain high quality nanobubble water by improving the generation efficiency of nanobubbles by imparting collision and pressure to the mixed air in the process of moving the mixed water, as well as smoothly supplying water. It is about.

Generally, nano bubbles are microscopic bubbles which are not visible to the eye, and are 1 / 2,000 of normal bubbles, fine air particles having a skin pore size of 25 μm or less, and when extinguished, 1) 40KHz ultrasonic wave generation, 2) It generates high sound pressure of 140db and 3) instantaneous high heat of 4,000 ~ 6,000 degrees.

In other words, general bubbles rise in water and rupture at the surface, but nano-bubbles are reduced by pressure in water and generate various energy and disappear.

And such nano-bubbles are mainly generated when the water and air are violently rotated into ultra-fine bubbles.

Such nano bubbles are utilized in various fields by physical and chemical properties such as "gas dissolving effect, self-pressing effect, and charging effect", and in recent years, they are used in various aquaculture and hydroponics in the fishing and agricultural fields. It is used for precision diagnosis in the medical field, and is used for physical therapy, high purity water treatment, and environmental devices in various fields.

In other words, it is widely used in hot spring baths for cancer diagnosis, and it is known to regenerate skin and to have excellent sterilizing effect.

Such nano-bubbles are produced in a variety of ways, such as swirling liquid suspension, state mixer, injector, banchuri, pressure dissolution, ultrasonic, electrolysis, microporous filter.

In order to generate nanobubbles through the various types of nanobubble generators such as these, nanobubbles are generated by converting a gas into microbubbles by receiving a liquid (feed water) mixed with a gas.

In the above process, the supply water is converted into micro bubbles through a process in which the feed water containing bubbles is separated and compressed while passing through the micro pipeline of the generating means having the micro pipeline.

As one of the nanobubble generating device for generating nanobubbles as described above, there is a Korean Patent Registration No. 10-1146040 (name: nanobubble generating device), the nanobubble generating device, as described in the publication, A bubble generating chamber having a water inlet for inflowing water, an air inlet for inflowing air, and an outlet for discharging air, and 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 a rotating disk having a plurality of induction holes for introducing water introduced through the air inlet, and provided to be in close contact with the moving direction of water and air of the rotating disk, and branching the water and air induced through the induction hole to the outside direction. And a plurality of stirring pieces protruding in the direction of the rotating disk to agitate water and air according to the rotation of the rotating disk. It consists of a disc information.

Accordingly, since water and air are agitated while being rubbed with the stirring pieces, as well as being rubbed while passing through the jig jacks between the stirring pieces, the water and air are crushed while being strongly stirred and simultaneously compressed.

The microbubble generator of such an impact type not only requires a high pressure of 5 to 20 bar, but also has a disadvantage in that the structure and equipment of the apparatus are complicated by a large flow loss, requiring a large number of nozzles and a large mixing tank. .

On the other hand, the microbubble generating device of the swinging liquid flow method, as in the impact nozzle method, 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 form In this case, the nanobubbles are generated by the vortex pressure generated while the vortex tube is formed and the mixed water is transported while forming the vortex.

In recent years, there is a situation that a nanobubble generator for living water is proposed to increase the use efficiency by generating a nanobubble in the tap water supplied when using the domestic water, such as washing, washing, bathing, etc. by attaching to a faucet in a general home.

In Korea Patent Registration No. 10-2012-7033796 (name: bubble generator), as described in the publication, it is opened between the pressure liquid supply member and the discharge member for discharging the liquid supplied from the pressure fluid supply member, A bubble generator for generating microbubbles in the liquid discharged from the discharge member, comprising: an upstream main body provided with a first flow path that retracts toward a downstream side, and a classification housed in the first flow path to form a plurality of liquid passage holes And a downstream body having a top and a second flow path attached to the upstream body and extending toward the downstream side, the downstream end of the first flow path being opposed to the upstream end of the second flow path. At least one surface roughness (Ra) of the contact surface of the upstream body or the contact surface of the downstream body, which is in contact with each other, is 0.2 to 6.3, and the minute contact between these contact surfaces is minute. There is a bubble generator is described to introduce the outside air into the inside from.
