Description of the Related Art Most conventional aeration, for example, aeration by a fine bubble generator installed in an aquatic growth apparatus, grows air from the pores of a tubular or plate-like fine bubble generator installed in a growth tank. Is it a method to subdivide air bubbles by pressurizing and jetting into water, or is it to subdivide air by introducing air into the growing water flow in which a shearing force has been formed by a rotating blade or air jet? Alternatively, it is a system in which air dissolved in water is vaporized by rapid depressurization of pressurized water to generate bubbles. Then, in aeration by the fine bubble generator having these functions, basically, necessary adjustments are made depending on the amount of air fed and the number of facilities of each fine bubble generator, etc. It is necessary to dissolve such gas in water with high efficiency and further promote water circulation.

Then, there have been problems of clogging and power cost increase that occur with the operation for a long time. Further, in the method of subdividing air into a water flow in which a shearing force is formed by a rotating blade or a bubble jet, a high rotation speed is required to generate cavitation, and the power cost There are problems such as blade corrosion and vibration that rapidly progress with the occurrence of cavitation, and there is also a problem that the generation rate of fine bubbles is low. In addition, in the method in which the gas-liquid two-phase flow collides with other rotary blades and protrusions, for example, in lakes, fish tanks, etc., fish and aquatic small organisms are destroyed, and the environment necessary for the growth of aquatic organisms is destroyed.

The device was large and expensive, and required a large operating cost. And, by any of the above conventional techniques,
For example, it was impossible to generate fine bubbles having a diameter of 20 μm or less on an industrial scale.

The essential point of the present invention is as shown in FIG. 1 which is an explanatory view of the principle of the device of the present invention. First, a conical space 100 is provided in the device container,
Further, a pressurized liquid introduction port 500 is opened in a tangential direction of a part of the inner wall circumferential surface of the space, and a gas introduction hole 80 is opened in the central portion of the conical space bottom portion 300. Swirling gas / liquid outlet 1 near the top of the space
01 is provided to configure the fine bubble generator. Therefore, by swirling the device body or at least the swirling gas-liquid outlet 101 in the liquid and pumping the pressurized liquid into the conical space 100 from the pressurized liquid inlet 500, a swirling flow is generated inside the device. A negative pressure portion is formed on the conical tube axis. By this negative pressure, the gas is sucked from the gas introduction hole 80, and the gas passes through the pipe axis having the lowest pressure, whereby the thin swirling gas cavity portion 60 is formed. In this conical space 100, a swirl flow is introduced from an inlet (pressurized liquid inlet) 500 to an outlet (swirl gas-liquid outlet) 10
1, the swirl flow velocity and the flow velocity toward the outlet increase at the same time toward the swirl gas / liquid outlet 101 as the cross section of the space 100 shrinks. With this swirl, the centrifugal force acts on the liquid and the centripetal force acts on the gas at the same time due to the difference in specific gravity between the liquid and the gas. Therefore, the liquid part and the gas part can be separated, and the gas is thread-shaped to the outlet 101. Then, it is ejected from there, but at the same time as the ejection, the turning is sharply weakened by the surrounding static liquid (water), and a sharp turning speed difference is generated before and after the turning. Due to the generation of the swirling speed difference, the filamentous gas cavity portion 60 is continuously and stably cut, and as a result, a large amount of fine bubbles, for example, fine bubbles having a diameter of 10 to 20 μm, are generated in the vicinity of the outlet 101. It is released into the outside liquid.

In the present invention, as shown in the principle explanatory view of the device of the present invention in FIG. 1, first, a conical space 100 is provided in the device container, and a liquid pressurized under the tangential direction is formed in a part of the inner peripheral surface of the space. Open the inlet 500,
Further, a gas introduction hole 80 is opened in the center of the conical space bottom 300, and a swirling gas / liquid outlet 101 is provided near the top of the conical space to form a fine bubble generator. Therefore, by swirling the device body or at least the swirling gas-liquid outlet 101 in the liquid and pumping the pressurized liquid into the conical space 100 from the pressurized liquid inlet 500, a swirling flow is generated inside the device. A negative pressure portion is formed on the conical tube axis. By this negative pressure, the gas is sucked from the gas introduction hole 80, and the gas passes through the pipe axis having the lowest pressure, whereby the thin swirling gas cavity portion 60 is formed. In this conical space 100, a swirling flow is formed from an inlet (pressurized liquid inlet) 500 toward an outlet (swirl gas-liquid outlet) 101, and the swirling gas-liquid outlet 10 is reduced as the cross section of the space 100 is reduced.
As it goes to 1, the swirling flow velocity and the flow velocity toward the outlet simultaneously increase. With this swirl, the centrifugal force acts on the liquid and the centripetal force acts on the gas at the same time due to the difference in specific gravity between the liquid and the gas. Therefore, the liquid part and the gas part can be separated, and the gas is thread-shaped to the outlet 101. Subsequently, it is jetted from there, but at the same time as the jet, the turning is sharply weakened by the surrounding static liquid (for example, water), and a sharp turning speed difference is generated before and after the turning. Due to this difference in turning speed,
The filamentous gas cavity portion 60 is continuously and stably cut, and as a result, a large amount of fine bubbles, for example, a diameter of 10 to 20 μm.
Micro bubbles of m are generated in the vicinity of the outlet 101 and are discharged to the outside of the device into the liquid.

With this swirl, the centrifugal force acts on the liquid and the centripetal force acts on the gas at the same time due to the difference in specific gravity between the liquid and the gas. Therefore, the liquid portion and the gas portion can be separated, and the negative pressure gas is formed into a filament. It will continue to the exit 101. Then, the gas is automatically sucked from the gas introduction hole 80 (self-priming), and the gas is taken into the swirling gas-liquid flow as a thin swirling cavity 60. Thus
The filamentous thin gas swirling cavity 60 at the center and the liquid swirling fluid around it are jetted from the outlet 101. At the same time as the jetting, the swirling is sharply weakened by the surrounding static liquid, and before and after that, the swirling is suddenly increased. A large turning speed difference occurs. Due to the generation of the swirling velocity difference, the filamentous gas cavity portion 60 at the swirling flow center is continuously and stably cut, and as a result, a large amount of minute bubbles, for example, minute bubbles having a diameter of 10 to 20 μm, are generated near the outlet 101. Occurs in.

Fine bubbles having a thickness of about 1 cm were accumulated on the entire water surface of the aquarium during operation. This device has a volume of 200
It was applicable to the purification of water in a pond of 0 m 3 or more. In the case of a small size, for example, the pump has a motor of about 30w and a discharge rate of 20 liters / minute.
It could be used in a water tank of about 3 m 3 . In addition, when applied to seawater, since micro bubbles are very likely to be generated, the use conditions can be further expanded. Figure 1

を発生する。Based on the explanatory views shown in FIGS. 11 to 14, four side discharge ports 71, 72, 73, 7 are provided at the central reflux port 6.
The generation structure of the fine bubbles when having No. 4 will be described below. The gas vortex tube 24 which swirls and descends the central portion 4c of the above-mentioned covered cylindrical body 4 and the swirling descending water-liquid flow 22 in the order of the swirling direction (viewed by arrow D) of the central reflux port 6 has four side surface discharges. It is sent toward the outlets 71, 72, 73, 74. FIG. 12 shows the state of being discharged to the first side surface discharge port 71. The lower portion 24b of the gas vortex tube receives the passage resistance due to the feeding and reduces the swirling speed, and a swirling speed difference is generated between the lower portion 24b and the upper portion 24a of the gas vortex tube, and the vortex tube is twisted and cut to generate fine bubbles. To do. Reference numeral 25 indicates a cutting portion.
FIG. 13 shows a state in which the gas vortex tube 24 receives a passage resistance that collides with the adjacent side wall 6a of the return port while the gas vortex tube 24 is being directed to the next second side surface discharge port 72. The lower part 24b of the gas vortex tube is the side wall 6a.
The turning speed is changed by colliding with the cutting part 2 and
Similarly, in step 5, fine bubbles are generated. FIG. 14 shows a state in which the gas vortex tube 24 is discharged to the second discharge port 72, and the swirling speed is different from that in FIG.
To generate fine bubbles. As described above, the discharge to the four side surface discharge ports 71, 72, 73, and 74 and the collision with the adjacent side wall 6a are alternately repeated four times during one turn, and the vortex tube upper and lower portions 24a and 24a are repeated each time. , 24b, a swirling speed difference is generated, and the vortex tube is cut to generate a large amount of fine bubbles.

And the number of turns of the gas vortex tube 24 and the number of cutting parts 25.
In order to enable a high number of turns, a high pressure pump
It is necessary to swirl the water liquid in the initial stage. As the number of turns increases, the cutting portion (face) 25 becomes smaller, the gas elution due to the negative pressure becomes remarkable, and it becomes possible to generate smaller and larger amount of fine bubbles. In addition, the side discharge port 7
The number of fine bubbles also increases by increasing the number of cells. From the experimental results, it was found that the optimum number of outlets was related to the amount of water introduced at a constant rotation speed, but at 40 liters / minute and a lift of about 15 m, the optimal number of outlets was four.

Following this, since the discharge direction is bent by 45 ° in the direction of the arrow D to project, the swirl type fine bubble generator 1 is installed in the water tank 13.
When installed inside (FIG. 16), a circulating flow in the direction of the arrow D is generated around the swirl-type generator 1, which is discharged from the discharge connecting pipe 9 into the water tank 13 as a swirl jet, and oxygen is generated. The contained fine bubbles are evenly distributed in the water tank 13. In the above configuration example device 1 of the present invention, the bubble diameter 1
A water stream containing fine bubbles, of which 0 to 20 μm accounted for 90% or more, was discharged. When installed in the water tank 13, the lower flow table 2 is preferably made of a heavy material, but when made of plastic, a heavy stainless steel plate may be further attached to the bottom thereof. Further, if the covered cylindrical body 4 is made of a transparent material, there is an advantage that the formation of the swirling rising water liquid flow and the like and the formation of the descending reflux of them are observed.
