Description

  The present invention relates to a gas-liquid mixed solution generating apparatus that generates a gas-liquid dissolved liquid in which fine bubbles are stably present, a method for producing fine bubble water using the same, these gas-liquid mixed liquid generating apparatus, and fine bubbles The present invention relates to a fine bubble liquid produced using a water production method and containing bubbles of nanometer order to micrometer order, and an electronic device using the fine bubble water.

  Conventionally, it is known that a gas-liquid solution containing fine bubbles having a size of nanometer order to micrometer order has unique properties such as a cleaning effect and a blood flow enhancement effect.

  Patent Document 1 proposes a conventional gas solution generator that generates a gas liquid solution in which fine bubbles are stably present.

  FIG. 4 is a block diagram schematically showing a configuration example of a conventional gas solution generator disclosed in Patent Document 1. As shown in FIG.

  As shown in FIG. 4, in the conventional gas solution generator 100, the gas introduced from the gas inlet 101 is indicated by the symbol A, and the water flowing in from the raw water inlet 102 is indicated by the symbol B. . These gas and water are mixed in the gas-liquid mixing unit 103 to become gas-dissolved water.

  Here, this gas-dissolved water is repeatedly circulated by the circulation mechanism 201 through the gas-liquid mixing unit 103, the pressure pump 104, the shearing / dissolution unit 105, the microbubble generation unit 106, and the nanobubble generation unit 107.

  Meanwhile, the microbubble generating unit 106 generates microbubbles from the gas A in the water, and the nanobubble generating unit 107 generates nanobubbles from the microbubbles using ultrasonic waves in the water.

  A repeat circuit 202 constituting the circulation mechanism 201 is shown. The repeat circuit 202 causes the gas-dissolved water (nanobubble water) discharged from the nanobubble generating unit 107 to flow into the gas-liquid mixing unit 103 again.

  In this way, the gas-dissolved water is repeatedly circulated through the gas-liquid mixing unit 103, the pressure pump 104, the shear / dissolution unit 105, the microbubble generation unit 106, and the nanobubble generation unit 107 by the circulation mechanism 201. Thereby, the process which mixes gas and a liquid, and the process which converts this gas into a micro bubble and also a nano bubble are performed repeatedly. A cooler 108 is connected to the shearing / dissolving unit 105 to cool the heat generated in the shearing / dissolving unit 105.

  Furthermore, the pressurizing pump 104 and the shearing / dissolving unit 105 perform processing for further promoting mixing and dissolution. Thereby, the gas dissolution concentration in gas dissolution water can be raised. With such a circulation mechanism 201, it is possible to control the gas dissolution concentration in the gas dissolution water.

  Further, the microbubble generation unit 106 converts the gas in the gas-dissolved water into microbubbles, and the nanobubble generation unit 107 repeats the process (two-step process) of further converting the microbubbles into nanobubbles. As a result, microbubbles and gas remaining without being converted into nanobubbles in one circulation process are also converted into nanobubbles by repeating the circulation process.

  As a result, the purity of the nanobubbles in the water increases, and conversely the proportion of microbubbles decreases. This makes it possible to generate gas-dissolved water containing nanobubbles at a high concentration and containing a small amount of microbubbles.

  Such gas-dissolved water has an advantage that it is suitable for use as cleaning water in the manufacturing process of semiconductor devices and FPDs, for example. The reason for this is that this gas-dissolved water contains a high concentration of nanobubbles that contribute greatly to cleaning, has little contribution to cleaning, and has a content of microbubbles that may damage semiconductor devices and FPD due to crushing. Because there are few. According to this cleaning water, damage to the semiconductor device and the FPD can be suppressed, and the yield of these can be improved.

  In short, in the conventional gas solution generator 100 proposed in Patent Document 1, the gas-liquid mixing unit 103 for mixing the gas and the liquid and the liquid containing the gas flow in, and the gas contained in the liquid is micronized. A microbubble generation unit 106 that converts into bubbles, a liquid containing the microbubbles flows in, a nanobubble generation unit 107 that converts microbubbles contained in the liquid into nanobubbles, and a liquid that includes the nanobubbles are gas-liquid mixed. A circulation mechanism 201 is provided that increases the gas dissolution concentration in the liquid by circulating through the section 103, the microbubble generation section 106, and the nanobubble generation section 107.

(Embodiment 1)
FIG. 1 is a schematic diagram illustrating a configuration example of a main part of a gas-liquid mixed liquid generating apparatus according to Embodiment 1 of the present invention.

  In FIG. 1, the gas-liquid mixed-liquid production | generation apparatus 20 of this Embodiment 1 is the water tank 1 which can store a predetermined amount of gas-liquid solution, The deaeration film | membrane 2 which enables the entrance / exit of air for dust prevention, A light emitting source 3 that emits light, an optical sensor 5 that receives scattered light of the emitted light, a water pump 6 that takes water from the water tank 1 and pressurizes it toward the Venturi tube 7, and pressurizes water by the water pump 6. A Venturi tube 7 that performs gas-liquid mixing, an air introduction tube 8 that supplies air to the Venturi tube 7, a dust-proof air filter 9 provided in the air introduction tube 8, and an ultrasonic transducer 10 that performs ultrasonic vibrations And a helical tube 11 that is a helical pipe for applying ultrasonic vibration to the gas-liquid dissolved solution that is pressurized and flows in from the venturi tube 7, and a solvent container 12 in which the helical tube 11 is accommodated. ing.

  The water tank 1 can store a predetermined amount, for example, several CC to 200 CC, of a gas-liquid solution in which fine bubbles of nanometer order to micrometer order exist in water. In the case of several CCs, a fine mist of nanometer order to micrometer order can be generated as fog (mist). That is, by opening a part of the upper part of the water tank 1 in the gas-liquid mixture generating apparatus 20, it is possible to generate a mist-like gas-liquid mixture containing fine bubbles.

  The degassing membrane 2 is a membrane for the air in the water tank 1 to enter and exit from the outside according to the amount of gas-liquid dissolved solution in the water tank 1, and only the excess gas is discharged and the liquid remains in the water tank 1. It is a film. The deaeration membrane 2 also serves as a dust mixing prevention membrane. Thereby, the deaeration membrane 2 has a mechanism for removing excess gas from the fine bubble water in the water tank 1.

  The light emission source 3 is provided at a predetermined depth position (intermediate position) of the transparent side wall of the water tank 1, and emits light toward the opposing transparent side wall inside the water tank 1.

  The optical sensor 5 is provided at a predetermined depth position on the transparent side wall of the water tank 1, and is provided at a position shifted from the predetermined depth position facing the light emitting source 3 by a predetermined distance vertically or horizontally. Irradiation light from the light source 3 hits the gas-liquid solution in the water tank 1 to become scattered light 4 and receives the scattered light 4. In order to receive the scattered light 4, an optical sensor 5 is disposed at a position shifted by a predetermined distance from the position facing the light emitting source 3.

  It has a function of detecting the fine bubble generation concentration by the laser light or LED light from the light source 3 and the optical sensor 5.

  The water flow pump 6 has one end connected to the side wall near the bottom of the water tank 1 and the other end connected to the venturi tube 7 side, and pressurizes the water in the venturi tube 7 by driving the water flow pump 6. Yes. The water flow pump 6 introduces a gas-liquid solution into the spiral tube 11 through the venturi tube 7 in a state where air is dissolved in pressurized water. By driving the water flow pump 6, circulation returning from the water tank 1 to the spiral pipe 11 through the venturi pipe 7 and from the spiral pipe 11 to the water tank 1 is repeated a predetermined number of times.

  Further, a plurality of projections may be provided in the water flow pump 6 as the pump means, and the projections may be vibrated by the water flow to generate ultrasonic waves.

  Further, the water flow pump 6 has a function of improving the output of the water flow pump 6 by providing a swivel part directly connected to the inlet side and the outlet side of the water flow pump 6.

  The Venturi tube 7 is provided between the spiral tube 11 and the water flow pump 6, and has a large tube inner diameter again from a tube having a large tube inner diameter through a tube having a small tube inner diameter. When the inner diameter of the Venturi tube 7 is reduced, the flow velocity increases and the pressure decreases. When the flow rate of water in the tube is increased, when the tube inner diameter is reduced, air is supplied from the air introduction tube 8 and the air dissolves in the water. However, when the tube inner diameter is increased again, fine bubbles are deposited again. Come on.

  The air introduction pipe 8 communicates with the venturi pipe 7 where the air is narrowed, and introduces air into the water from the outside via the air introduction pipe 8. One end of the air introduction pipe 8 is opened to the outside, and the other end is communicated with a portion of the venturi pipe 7 where the pipe inner diameter is reduced. In the portion where the tube inner diameter of the Venturi tube 7 is narrowed down, the flow rate of water is increased and the internal pressure is lowered. The air dissolved in the water appears as fine bubbles when the tube diameter increases.

  The air filter 9 is a filter provided for dust prevention at an opening that takes in air from the outside opposite to the opening that takes in air from the narrowed portion of the venturi pipe 7 of the air introduction pipe 8.

  The ultrasonic vibrator 10 is provided at the bottom of a container containing a solvent such as water, and efficiently applies ultrasonic vibration to the gas-liquid mixture in the spiral tube 11 in the container via the solvent.

  The spiral tube 11 is provided in a container containing a solvent such as water. Ultrasonic vibration is effectively applied to the gas-liquid mixture in the spiral tube 11 through a solvent to further refine the gas-liquid mixture in the spiral tube 11. In order to further refine the bubbles by applying ultrasonic vibration to the gas-liquid mixture in the spiral tube 11, the spiral tube 11 is formed in a spiral shape so that a tube as long as possible can be provided in the container. doing. The helical tube 11 has a length in a range where ultrasonic cavitation extends, and if the helical tube 11 is too long, pressure loss increases.

  In the solvent container 12, the ultrasonic vibrator 10 is disposed below the bottom surface of the container, and the bottom surface of the container is filled with a solvent such as water. A spiral tube 11 is accommodated in a container filled with a solvent such as water. One end of the helical tube 11 is communicated with the other end of the venturi tube 7 that enters from the bottom wall of the solvent container 12, and the other end of the helical tube 11 protrudes from the side wall of the solvent container 12 and extends from the upper side wall of the water tank 1. The gas-liquid mixture in the spiral tube 11 is further refined by the ultrasonic vibrator 10 and returned to the water tank 1 in communication with the inside of the water tank 1.

  By covering the exterior of the solvent in the solvent container 12 to which the ultrasonic waves are applied with a material having a large difference in specific acoustic impedance from the solvent, the ultrasonic waves can be reflected so that the ultrasonic waves can be used repeatedly.

  After circulating the circulating water for a certain period of time, it has a function of changing the number of revolutions of the water flow pump 6 and the ultrasonic frequency to give it to the gas-liquid mixture.

  In short, the gas-liquid mixed liquid generating apparatus 20 includes a water tank 1 for storing fine bubble water as a fine bubble liquid, and a venturi as a venturi pipe means for precipitating bubbles after dissolving the gas in the circulating water from the water tank 1. An ultrasonic wave application tank that generates ultrasonic bubbles by applying ultrasonic waves to the circulating water from the tube 7 and the venturi pipe 7, and returns from the water tank 1 via the venturi pipe 7 to the ultrasonic wave application tank and further to the water tank 1. A water flow pump 6 as a pumping means for circulating the fine bubble water is disposed at least one between the water tank 1 and the venturi pipe 7, between the venturi pipe 7 and the ultrasonic wave application tank, and between the ultrasonic wave application tank and the water tank 1. That's fine. Here, the water pump 6 is disposed only between the water tank 1 and the venturi pipe 7.

  This ultrasonic wave application tank is a spiral pipe as a helical pipe that passes through the ultrasonic vibration propagating solvent (water) in the solvent container 12 stored in the ultrasonic wave application tank and the microbubble water immersed in the solvent. 11 and an ultrasonic transducer 10 as ultrasonic vibration means for generating ultrasonic bubbles by propagating ultrasonic vibrations from the solvent to the fine bubble water in the spiral tube 11.

  As a method for producing fine bubble water according to the first embodiment, circulating water from the water tank 1 is sent out to the venturi pipe 7 by the water flow pump 6, and after the gas is dissolved in the circulating water from the water tank 1 by the venturi pipe 7 The fine water bubbles in the water tank 1 can be obtained by repeating the circulation with the water pump 6 after applying ultrasonic waves to the circulating water in which the air bubbles have been deposited in the ultrasonic wave application tank to generate fine bubbles and then returning to the water tank 1. Produce water.

  With the above configuration, the water supplied from the water tank 1 and pressurized from the water flow pump 6 is sent out toward the venturi tube 7, and the air through the air filter 9 from the air introduction tube 8 is self-sucked by the venturi tube 7 and is supersaturated. By expanding the tube diameter of the gas-liquid dissolved solution in a state at once, fine bubbles of atmospheric components are precipitated in water.

  Next, when the tube diameter of the Venturi tube 7 is increased, fine bubbles are deposited in the water, and a gas-liquid mixture containing the fine bubbles is introduced into the spiral tube 11. When the gas-liquid mixed solution passes through the spiral tube 11, the ultrasonic vibrator 10 applies ultrasonic vibration to the spiral tube 11 through water as a solvent to further reduce the particle size of the fine bubbles in the water tank 1. Returned.

  In this way, the gas-liquid solution is circulated from the water tank 1 to the water tank 1 through the water flow pump 6 by further reducing the particle size of the fine bubbles in the venturi pipe 7 and the helical pipe 11. By continuing this circulation, water with a finer bubble size and higher bubble concentration can be produced.

  During the repetition of these steps, the concentration of fine bubbles can be further improved by changing the discharge pressure of the water pump 6 and the ultrasonic vibration of the ultrasonic vibrator 10.

  Since even a small amount can produce fine bubbly water within a few minutes, it can be used for personal drinking or in a narrow range. The Venturi tube 7 of each component has a gas dissolving function, the ultrasonic transducer 10 and the spiral tube 11 have a fine bubble forming function, and the gas-liquid mixed liquid is circulated to increase the number of components. A mist-like fine mixture containing fine bubbles of water or fine bubbles can be obtained.

  FIG. 2 is a diagram illustrating the center diameter of fine bubbles and the number of fine bubbles per unit volume with respect to the number of circulations performed by the gas-liquid mixed liquid generating apparatus 20 according to the first embodiment. FIG. 3 is a graph showing the relationship between the center diameter of the fine bubbles and the number of fine bubbles per unit volume with respect to the number of circulations in FIG.

As shown in FIGS. 2 and 3, as the number of circulations performed by the gas-liquid mixed liquid generating apparatus 20 increases, for example, when the number of circulations is 1, the number of circulations is 5 when the center diameter of the fine bubbles is 100. Thus, the center diameter of the microbubbles is 50, which is half of that, and the center diameter of the microbubbles becomes 10 which is 1/10 when the circulation frequency is 30 times. Further, for example, when the number of circulations is 1, the number of fine bubbles per unit volume is 1E4 (1 × 10 ⁴ ), and when the number of circulations is 5 and the number of fine bubbles per unit volume is 1E6 ( 1 × 10 ⁶ ), and the number of circulations is 30 times, and the number of fine bubbles per unit volume is 1E10 (1 × 10 ¹⁰ ). Accordingly, the center diameter of the fine bubbles with respect to the number of circulations and the number of fine bubbles per unit volume also increase dramatically as the number of circulations increases and the center diameter of the fine bubbles decreases.

  As described above, according to the first embodiment, in order to reduce the number of constituent members, each member is carefully selected and achieved by combining a plurality of functions. The water flow pump 6 uses a vortex pump to combine the function of pressurizing the circulating water and the function of generating cavitation, and by providing a swivel part having the same axis for the water flow on the input side and the water flow on the outlet side, the energy saving function is also achieved. Use together. The Venturi tube 7 can be self-supplied with gas and have a function of generating bubbles, and the ultrasonic tank can have a reflection function to apply sound waves in a complex manner. Furthermore, by circulating the whole, gas can be dissolved to the limit, bubble generation and bubble shredding can be repeated, and the bubble particle size and concentration can be brought into an equilibrium state.

  Thereby, in the gas-liquid mixed liquid production | generation apparatus 20 of this Embodiment 1, in order to produce | generate a fine bubble by gas-liquid mixing with the venturi tube 7, and providing an ultrasonic wave to a gas-liquid mixed liquid with an ultrasonic application tank, or Although only a small amount of a mist-like gas-liquid mixture can be produced at a time, a method that can reduce the energy required for nano-order fine bubbles can be proposed.

  The gas-liquid mixture containing fine bubbles is as small as about 200CC, but it can make gas-liquid mixture with a high concentration of fine bubbles, which can be installed in consumer electronic devices and has fine bubbles Efficacy can be developed with inexpensive equipment.

  In this way, in order to repeatedly generate gas bubbles by mixing the gas and liquid in the Venturi tube 7 and applying ultrasonic waves to the gas and liquid mixture in the ultrasonic wave application tank, a gas and liquid mixture containing nanobubbles is used. The number of parts to obtain can be greatly reduced from the conventional one, and the configuration can be simplified and downsized.

  Although not specifically described in the first embodiment, the gas-liquid mixed liquid generating apparatus 20 of the first embodiment is incorporated into a washing machine or a washing machine, for example, a face washing machine, a face washing machine, a dish washing machine, or the like to form fine bubbles. It can be washed with water or washed for good washing, water retention and sterilization. The gas-liquid mixed liquid generating apparatus 20 of the first embodiment can be used when the amount of fine bubble water used in a small size may be small (the volume of the water tank 1 is about 200 CC, for example). The size of the gas-liquid mixed liquid production | generation apparatus 20 of this Embodiment 1 is about 1 liter whose one side is 10 cm. The gas-liquid mixed liquid generating apparatus 20 of the first embodiment having a small volume and a reduced weight can be used as a micro / nano bubble engine. Fine bubble water can also be used as drinking water or lotion. Since those containing hydrogen have a reducing action, they become oxidation-resistant agents. For improving blood flow, fine bubble water can be used as hot water in the bath. In this case, since a large amount of fine bubble water is required, the volume of the water tank 1 is required to be, for example, 1000 CC or more, which increases the overall size of the gas-liquid mixed liquid generating apparatus 20 of the first embodiment. However, the size can be greatly reduced as compared with the conventional one. When ozone is contained in the fine bubble water, there is a further sterilizing effect. When oxygen is contained in the fine bubble water, the active action can be further enhanced. Inclusion of carbonic acid in the fine bubble water further improves blood circulation.

  As described above, for example, a washing machine, a refrigerator, a washing machine, such as a facial washing machine, a face washing machine, a dishwashing machine, or the like that uses the fine bubble water containing fine bubbles produced by the gas-liquid mixed liquid production apparatus 20 according to the first embodiment. Can be obtained.

  Further, although not particularly described in the first embodiment, the gas-liquid mixed liquid generating apparatus 20 of the first embodiment does not simply generate ultrasonic bubbles by applying ultrasonic vibration to the gas-liquid mixed liquid, While passing the gas-liquid mixed solution through the thin and long spiral tube 11, ultrasonic vibration can be applied to the spiral tube 11 through a solvent to efficiently further reduce the particle size of the fine bubbles in the gas-liquid mixed solution. . As described above, even in the gas-liquid mixed liquid generating apparatus 20 of the first embodiment that is small in size and reduced in weight, the ultrasonic vibration is efficiently applied to the gas-liquid mixed liquid, and the particle diameter of the fine bubbles is further efficiently increased. Can be small.

  Further, although not particularly described in the first embodiment, in the gas-liquid mixed liquid generating apparatus 20 of the first embodiment, the air-introducing pipe 8 communicating with the venturi pipe 7 is connected to the gas-liquid mixed liquid a predetermined number of times. There was no explanation about shutting off after circulation, but by shutting off the air introduction tube 8, the air can be introduced without gas-liquid mixing, that is, without containing new large bubbles. The fine bubbles of the gas-liquid mixed solution in the spiral tube 11 can be further refined by ultrasonic vibration through the Venturi tube 7 and the density of the fine bubbles can be improved and the bubble size can be increased by circulating this. It can also be made smaller.

It is understood that the scope of the present invention should be construed only by the claims. It is understood that those skilled in the art can implement an equivalent range from the description of the specific preferred embodiment 1 of the present invention based on the description of the present invention and the common general technical knowledge.
