Description

Nano-bubble generator

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a nano bubble generating device for generating nano bubbles which are micro bubbles having a diameter of nano units, and more particularly, The present invention relates to a nano bubble generator capable of improving the efficiency of generating nano bubbles and achieving economical benefits through structural simplification and downsizing.

In general, nano bubbles are microscopic air bubbles that can not be seen by eyes. They are 1 / 2,000 size of normal bubbles and are minute air pores of skin pores less than 25 μm. When they disappear, 1) 40KHz ultrasonic waves are generated. 2) And 3) an instantaneous high temperature of 4,000 to 6,000 degrees is generated.

That is, the normal bubbles rise in the water and rupture at the surface, but the nano bubbles are reduced by the pressure in the water and generate various energy and disappear.

Such a nano bubble occurs when the water and the air are vigorously rotated by the ultra-fine bubble.

Such nano bubbles have been utilized in various fields by physical and chemical characteristics such as "gas dissolving effect, self-pressurizing effect, and charging effect". In recent years, the nano bubbles have been used for various aquaculture and hydroponics, In medical field, it is used for precision diagnosis, and in various fields, it is used in physical therapy, high-purity water treatment, environment device and the like.

In other words, the field of use is wide ranging from hot spring bath to cancer diagnosis, it is known that it has excellent sterilization effect as well as regenerating skin.

The nano bubbles are generated by various methods such as a circulating liquid flow type, a state liquid type, an ejector type, a vanishing type, a pressure dissolving type, an ultrasonic type, an electrolysis type, and a micro pore filter type.

In order to generate nano bubbles through the various types of nano bubble generating devices, nano bubbles are generated by converting a gas into a fine nano-bubbles by supplying a liquid (supply water) mixed with a gas.

The process of converting the supply water to the microfluidic system is performed through the process of separating and compressing the supply water containing the bubbles while passing through the micropilot of the generation means provided with the microfilm.

As described above, Korean Patent Registration No. 10-1146040 (name: a nano bubble generator) is one of the nano bubble generating devices for generating nano bubbles. The nano bubble generating device, as described in the publication, A bubble generation chamber provided with a water inlet port through which water is introduced and an air inlet port through which air is introduced and a discharge port through which air is introduced; a water supply port provided between the water inlet port and the air inlet port and the discharge port of the bubble generation chamber, And a plurality of induction holes through which water introduced through the air inlet is guided, and a plurality of induction holes for guiding water and air introduced through the induction hole in the outward direction, And a plurality of stirring pieces protruded in the direction of the rotating disk to stir the water and air according to the rotation of the rotating disk It consists of a disc information.

As a result, water and air are stirred while being frictioned with the agitating pieces, and friction between the agitating pieces is made while passing through the jig jack. Therefore, water and air are strongly stirred and pressed at the same time.

Such a shock-type micro-bubble generator requires a high pressure of 5 to 20 bar, has a large flow loss, requires a large number of nozzles and a large-volume mixing tank, thereby complicating the structure and equipment of the apparatus .

On the other hand, in the apparatus for generating fine bubbles in the circulating liquid flow system, as in the impact type nozzle system, a mixed water in which water and air are mixed is transferred through the space in the form of a vortex, And the nano bubbles are generated by the vortex pressure generated while the mixed water is formed while forming the vortex flow.

However, such a circulating liquid flow type micro-bubble generating apparatus has a problem that a micro-bubble can not be generated through a single nozzle, a high pressure is required, and a bulky mixing tank is required.
