Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a device for producing fine bubble water in which a large amount of dissolved oxygen is greatly increased by dispersing and mixing a large number of fine bubbles in water. It is used for producing bath water, washing water, etc.

[0002]

2. Description of the Related Art When a large number of air bubbles are dispersed and mixed in water,
It has been widely known that the amount of dissolved oxygen in water increases and the growth of plants is promoted by activating water, or that the washing capacity of water is increased to reduce the amount of detergent used. There is.

FIG. 4 shows conventional bubble water (bubble-containing activated water).
Is an example of the manufacturing apparatus of the above, the stirring blade 14 having a large number of small holes 13 is rotated at high speed in the casing 15, and the water supplied from the water supply port 16 is agitated and mixed with the air supplied from the air supply port 17. By doing so, the fine bubbles having an average bubble diameter of 20 μm to 50 μm are 5 to 30 (VOL%).
The bubbly water contained therein is continuously taken out from the outlet 18 (Japanese Utility Model Publication No. 59-184827).

However, in the apparatus shown in FIG. 4, the stirring blade 1
In addition to requiring a considerable amount of drive energy for high speed rotation of No. 4 and a separate air supply compressor, there is a problem in that inevitably an increase in size of the device and complication of operating operations are unavoidable. In addition, in the conventional bubble water manufacturing apparatus, there is considerable variation in the diameter of bubbles mixed in water,
It is extremely difficult to adjust the bubble diameter and its mixing ratio. As a result, it is difficult for the aerated water to be completely emulsified, and there is a problem that so-called ideal emulsion-shaped aerated water cannot be obtained. Furthermore, in the conventional bubbling water production apparatus, not only are there variations in the diameter of bubbles mixed into water, but also because the mixing is relatively insufficient, bubbles may escape early from the produced bubbling water. However, there is a drawback that various problems occur in using the bubbly water.

[0005]

DISCLOSURE OF THE INVENTION The present invention has the above-mentioned problems in the conventional bubble water generator, namely, the structure of the device is complicated and large, and the operation is complicated and troublesome. It is intended to solve problems such as not being able to obtain ideal bubble water in which fine bubbles of uniform diameter are mixed, and the fact that bubbles escape from the bubble water relatively quickly, and it is compact and easy to handle. Moreover, the present invention provides a fine bubble water generator capable of easily obtaining ideal emulsion-like bubble water that contains fine bubbles having a uniform particle size at a high mixing ratio and uniformly.

[0006]

According to the present invention, there is provided an air ejector having a water source connected to a water source having a predetermined water pressure, an air intake valve connected to an air intake side of the air ejector, and water of the air ejector. A bubble-refining mixer connected to the outlet side for refining bubbles in the bubble-water, and an emulsification tank connected to the outlet side of the bubble-refining mixer for re-stirring and mixing the fine bubble water have the basic structure of the invention. The air bubbles ejected and mixed into the water by the air ejector are atomized by the bubble atomization mixer and remixed into the water, and the kinetic energy of the fine air bubble water is used in the emulsification tank. Then, by stirring again, the finely bubbly water which has been almost completely emulsified can be taken out.

[0007]

The water flows through the air ejector, so that the air is sucked and mixed into the water through the air suction valve. The bubble water in which air is suction-mixed is circulated and re-stirred while the bubbles in the bubble finer mixer are circulated in the bubble finer mixer. The fine bubble water from the fine bubble bubble mixer is subsequently introduced into the emulsification tank and again stirred and mixed by using the kinetic energy held by the fine bubble water. As a result, the fine bubble water is almost completely emulsified and becomes active water having an extremely high dissolved oxygen content and is taken out to the outside.

FIG. 1 is a block configuration diagram of an automatic fine bubble water generation device according to the present invention, FIG. 2 is a sectional view of a fine bubble mixing mixer, and FIG. 3 is a sectional view of an emulsification tank.

In FIG. 1, 1 is a raw water tank, 2 is an air suction valve, 3 is an air ejector, 4 is a pump, 5 is a bubble atomizing mixer, 6 is a pressure gauge, 7 is an emulsification tank, and 8 is The pressure control valve 9 is a bubble water storage tank. As shown in FIG. 2, the bubble-refining mixer 5 is formed by filling a metal or synthetic resin cylindrical body 5a with a porous ceramic granular filler 5b, and the specific gravity of the porous ceramic is from 2.5 to 2.5. A spherical body having a diameter of 4.0 and a diameter of 1 to 3 mm is used.

In this embodiment, the porous ceramic granular filler 5b has a spherical shape.
4 mm, cylindrical body with a length of 2 to 5 mm and an outer diameter of 2 to 4 mmφ,
It is also possible to use a cylindrical body having an inner diameter of 1 to 2 mmφ and a length of 2 to 5 mm. It is also possible to use far-infrared radiation as the porous ceramic material. Furthermore,
In the present embodiment, the bubble-refining mixer 5 has a structure in which a cylindrical body 5a is filled with a porous ceramic granular filling body 5b. However, the stirring blade inserted into the casing body is rotated at high speed by water flow or external power. It is also possible to use a mixer-type miniaturized mixer. In addition, as the material of the granular filler 5b, a porous ceramic material having a hard and dense crystal structure, which is not easily cracked or worn, and which has water resistance, alkali resistance, and acid resistance is desirable.

As shown in FIG. 3, the emulsification tank is composed of a sealed outer tank 7a and an upper open inner tank 7b which is concentrically arranged inside the outer tank 7a. Fine bubble water 10 pressed downward
Flows in the inner tank 7b as an ascending flow, descends as a downward flow into the outer tank 7a from above, and is discharged outward from the outlet 7c.

Next, the operation of the present invention will be described. Referring to FIG. 1, first, a pump 4 (for example, 100V, 0.4
KW, 12 l / min) is started, and the water in the raw water tank 1 is forced into the bubble-refining mixer 5 through the air ejector 3. At the same time when the pump 4 is started, the opening degree of the air suction valve 2 is adjusted to control the mixing amount of the air 11 mixed into the absorbed water via the air ejector 3 to a predetermined value.

In this embodiment, the water in the raw water tank 1 is press-fitted into the bubble atomizing mixer 5 by the pump 4, but a water source (for example, a water supply) that can obtain a water pressure of 2 to 5 kg / cm or more. If there is equipment, the raw water tank 1 and the pump 4 may be eliminated and tap water or the like may be directly supplied into the bubble atomizing mixer 5 through the air ejector 3. Further, in this embodiment, the air 11 is sucked and mixed into the water absorption 12 through the air suction valve 2. However, an ozone generator (not shown) is connected to the inlet side of the air suction valve 2 and the ozone generator concerned is connected. The ozone from the above may be suction-mixed into the water absorption alone or together with the air.

When the air intake valve 2 is opened, a predetermined amount of air 11 is generated by the suction force generated by the air ejector 3.
Are sucked and mixed into the water absorption 12. Further, the water (bubble water) 12a mixed with the air 11 continues to be 2 to 5 kg /
While being introduced into the bubble-refining mixer 5 at a pressure of cm ² and passing through the pores of the porous ceramic granular filler 5a filled in the cylindrical body 5a, relatively large bubbles in the bubble water 12a are dispersed. It is subdivided into fine bubbles having a diameter of about 1 to 10 μm, and is more uniformly stirred and mixed into water.

In the cylindrical body 5a, the porous ceramic granular filler 5b itself is also agitated and mixed by the water flow,
Repeated friction and collision with each other. As a result, the granular packing 5
So-called triboelectricity and piezoelectricity are generated in b. Further, so-called pyroelectricity is generated in the granular filling body 5b by being heated by collision or absorbing infrared rays or the like. When the granular filling body 5b is charged in this way, the molecules of water flowing inside thereof are electrolyzed or magnetized by the magnetic field generated by the discharge flow of the charging body, so-called water itself is also activated. Will be done.

The fine bubble water 10 of which the bubbles have been made fine by the bubble fine mixer 5 is continuously pressed into the emulsification tank 7 and circulates in the inner tank 7b while flowing as an upward flow. , From the upper opening to the outer tank 7
It is discharged into a and flows downward as a downward flow. During this time,
The fine bubble water 10 is sufficiently stirred and mixed again, and the fine bubble water 10 in the emulsion state in which the fine bubbles are uniformly dispersed is formed.

The fine bubble water 10 made into an emulsion state while passing through the emulsification tank 7 is sent to a fine bubble water storage tank 9 through a pressure control valve 8 and once stored therein, Water will be supplied to the necessary places. Needless to say, the fine bubbly water 10 may be directly supplied from the pressure adjusting valve 9 to a necessary place.

Fine bubble water 1 produced by the apparatus of the present invention
At 0, fine bubbles having a particle size of 1 to 30 μm (average particle size of 3 to 10 μm) are mixed at a mixing ratio of about 20 to 40 VOL%, and as a result, the dissolved oxygen in water has a value of a steady saturation value. It has been confirmed from the test results that the increase is 20 to 50%. In addition, emulsified fine bubble water 10
The fine bubbles inside do not easily separate from the water even when the water bubble 10 is allowed to stand, and are kept in an emulsified state for about 10 minutes. That is, since the storage time of the fine bubble water 10 is long, the use of the bubble water 10 is extremely convenient.

The air bubbles in the fine air bubble water form a relatively stable dispersion system and remain in the aqueous solution for a long time. Moreover, since the fine bubbles in the aqueous solution have a function of adsorbing organic substances and various fine particles, organic substances existing in water are aggregated and precipitated,
Water will be purified. Further, the fine bubbles in the aqueous solution have a function of entering the gaps of the scale that is solidified by rust, organic matter, etc., and dispersing (dissipating) the solidified body by a kind of peptizing action. Therefore, when used as washing water or the like, a desired degree of cleansing can be obtained with a smaller amount of detergent, and when used as bath water, the effect of washing the human body is improved. In addition, the fine air bubbles in the aqueous solution serve to replenish the dissolved oxygen that is consumed one after another, and thus prevent the anaerobicization of water and perform disinfection and sterilization, which is extremely convenient for washing and bath water. is there.
When an ozone generator is connected to the air inlet, the disinfection / sterilization action is further improved.

Can be realized.

Further, since the actions such as suction of air, atomization of bubbles and emulsification of fine bubbles water are all performed by utilizing the kinetic energy of the water flow, the operation of the device can be extremely simplified and the handling can be facilitated. It will be easy. Furthermore, the produced micro-bubble water is kept in an emulsion state for a long time, so that it retains its activity for a long time, which is extremely convenient for use.
