Description

Nano bubble generator

The present invention relates to a nanobubble generating device configured to maximize use efficiency by supplying air while pumping water and providing air mixed with water into nanobubbles.

In general, nanobubbles are ultra-fine bubbles that cannot be seen by the eye, and are microscopic air particles with a size of 1/2,000 of normal bubbles and less than 25㎛ of pores on the skin, and when extinct 1) 40KHz of ultrasonic waves are generated, and 2) 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, general bubbles rise in the water and rupture at the surface, but the nanobubbles shrink by pressure in the water, generating various energies and extinguishing.

In addition, nanobubbles as described above are mainly generated when water and air are violently rotated with ultra-fine bubbles.

Such nano bubbles are used in various fields due to physical and chemical properties such as "gas dissolution effect, self-pressurization effect, charging effect", and in recent years, especially in the fields of fishing and agriculture, they are used in various aquaculture and hydroponic cultivation. 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, the field of use is widely ranging from hot spring baths to cancer diagnosis, and it is known that it regenerates the skin and has excellent sterilization effects.

The nanobubbles as described above are generated in a variety of ways, such as a rotating liquid retention type, a state mixer type, an ejector type, a Venturi type, a pressure melting type, an ultrasonic type, an electrolysis type, and a microporous filter type.

In order to generate nanobubbles through such various types of nanobubble generators, a liquid (supplied water) mixed with gas is supplied and the gas is converted into microbubbles to generate nanobubbles.

In the above, the process of converting the feed water into micro-bubbles is performed through a process of separating and compressing the feed water containing bubbles while passing through the micro-pipe of the generating means provided with the micro-pipe.

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 generation chamber equipped with a water inlet through which water flows in, an air inlet through which air flows in, and a discharge port through which air flows in, and between the water inlet and the air inlet and the discharge port of the bubble generation chamber and rotated by being inserted into the shaft of the motor And a rotating disk provided with a plurality of guide holes through which the water introduced through the air inlet is guided, and the rotating disk is provided to be in close contact with the moving direction of water and air, and the water and air guided through the guide hole are branched outward. It consists of a fixed disk provided with a plurality of stirring pieces protruding toward 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 stirred while being rubbed against the stirring pieces, as well as friction while passing through the jig jack between the stirring pieces, so that water and air are strongly agitated and compressed at the same time as if crushed.

Such an impact-type microbubble generator requires a high pressure of 5 to 20 bar, as well as a large flow loss, and a large number of nozzles and a bulky mixing tank are required, thereby complicating the structure and equipment of the device. .

On the other hand, the microbubble generating device of the rotating liquid flow method generates nanobubbles through the transfer pressure introduced in the process of transferring the mixed water mixed with water and air through the space in a vortex, like the impact nozzle method. By forming a vortex type pipe, nanobubbles are generated by the vortex pressure generated while the mixed water is transferred while forming a vortex.

In recent years, a nanobubble generator for living water has been proposed to increase usage efficiency by generating nanobubbles in tap water supplied when household water is used for washing, washing, bathing, etc. by attaching it to the faucet in general households.

In Korean Patent Registration No. 10-2012-7033796 (name: bubble generator), as described in the publication, it is opened between a pressure liquid supply member and a discharge member that discharges the liquid supplied from the pressure fluid supply member, As a bubble generator for generating microscopic bubbles in the liquid discharged from the discharge member, an upstream main body provided with a first flow path that constricts toward a downstream side, and a classification in which a plurality of liquid passing holes are formed by being accommodated in the first flow path It is constituted by a downstream body having a top and a second flow path attached to the upstream body and widening toward a downstream side, wherein the downstream end of the first flow path faces the upstream end of the second flow path. , So that the surface roughness (Ra) of at least one of the contact surfaces of the upstream main body or the contact surface of the downstream main body in contact with each other is 0.2 to 6.3, and external air can be introduced into the interior from a minute gap between these contact surfaces. One bubble generator is described.
