Description

[Technical field]

[0001] The present invention relates to a method for producing hollow capsule-containing water, which is water containing hollow capsules formed by providing a coating film around air bubbles generated in water, and a method for using this hollow capsule-containing water. [Background technology]

[0002] The present inventor previously invented a fine-bubble water generating device, and also invented a method for producing so-called hollow nanocapsules using this fine-bubble water generating device (see, for example, Patent Document 1).

[0003] Simply put, in a microbubble water generator, a mixer mixes and stirs gas into supplied water, and the water into which this gas has been mixed and stirred is further stirred using a turbo mixer or the like, so that the gas mixed and stirred into the water becomes bubbles of micro to nano order sizes. Here, the gas that becomes the bubbles can be various gases such as hydrogen and carbon dioxide, and the target gas can be so-called microbubbles or nanobubbles.

[0004] In addition, in the micro-bubble water generator, the generated bubbles are charged by a potential applicator, which causes the bubbles to repel each other and suppresses recombination. In this state, the micro-bubble water generator adds a coating agent to the water containing the bubbles to form a coating film on the bubbles in the water, turning them into hollow capsules.

[0005] The hollow capsules remain charged by the electric potential applicator and can be captured by electrostatic action in a hollow capsule adsorption storage container made of hollow fiber tubes used in artificial dialysis, allowing the hollow capsules to be efficiently collected.

[0006] The present inventors have also invented a method for cultivating agricultural crops, which enables the effective cultivation of agricultural crops by spraying hollow nanocapsules prepared by the above-mentioned method, which contain nitrogen gas, hydrogen gas, carbon dioxide gas, etc., on the leaf surfaces of the crops (see, for example, Patent Document 2).

[0007] [Patent Document 1] Patent Publication No. 2021-045702 [Patent Document 2] Patent Publication No. 2022-021148 Summary of the Invention [Problem to be solved by the invention]

[0008] In paragraph

[0076] of the specification of the above-mentioned Patent Document 2, the inventor mentioned utilizing exhaust gas emitted during thermal power generation as a form of use of hollow capsules for the purpose of cultivating agricultural crops, but did not indicate a specific method of use, and the specific method of use was still under investigation.

[0009] It has now become possible to produce water containing hollow capsules that are beneficial for plant cultivation using exhaust gas emitted during thermal power generation, more specifically, exhaust gas produced by coal combustion in coal-fired power generation, thus completing the present invention. [Means for solving the problem]

[0010] In the method for producing hollow capsule-containing water of the present invention, a microbubble generator is used, which includes a bubble generating means for generating bubbles in water by mixing and stirring water and gas, a charging means for charging the bubbles, an encapsulation means for forming a membrane surrounding the bubbles to generate hollow capsules, and a recovery means for adsorbing and recovering the hollow capsules. In particular, in the method for producing hollow capsule-containing water, which includes a step of recovering hollow capsules using the microbubble generator and a step of generating water containing hollow capsules by passing water through the recovery means, the gas is recovered from exhaust gas generated by burning coal, and a removal step of removing harmful substances from the exhaust gas by a harmful substance removal device is included.

[0011] Furthermore, the method for producing hollow capsule-containing water of the present invention is characterized in the following respects. (1) The hazardous substance removal device is a Venturi scrubber equipped with a cyclone separator, and sprays microbubble water containing microbubbles that encapsulate gas whose main component is chlorine gas into the exhaust gas. (2) In the hazardous substance removal equipment, a fluororesin sheet is attached to the inner surface of the cyclone separation device. (3) Microbubble water is produced using hot water generated in factories that emit exhaust gases. (4) The gas recovered from the exhaust gas is nitrogen dioxide, sulfur dioxide or carbon dioxide.

[0012] Furthermore, in the method of using hollow capsule-containing water of the present invention, the hollow capsule-containing water produced by the above-mentioned method of producing hollow capsule-containing water is stored in a tank mounted on a drone, and the drone is flown to spray the hollow capsule-containing water. Furthermore, the drone is characterized in that it is equipped with an electrostatic nozzle at the end of a spray hose connected to the tank, and further in that spraying the hollow capsule-containing water on the leaf surfaces of plants activates photosynthesis in the leaves where the hollow capsule-containing water has been sprayed, thereby promoting the emission of oxygen. Effect of the Invention

[0013] According to the present invention, exhaust gas generated in the combustion of fossil fuels such as coal can be effectively utilized instead of simply being discarded, and in particular, can be utilized without placing an unnecessary burden on the environment.

[0015] In recent years, it has been reported that the stomata on the surface of leaves not only take in carbon dioxide (CO2) and release oxygen used in photosynthesis, but also take in nutrients. This is the function of nutrient absorption by the leaves through the stomata. Focusing on this point, fertilization techniques that involve spraying fertilizer components on the leaves are also being considered.

[0016] As one example of this, in an experiment in which plants were grown in an environment where the CO2 concentration in the atmosphere was 800 ppm or higher, compared to a normal atmospheric CO2 concentration of about 360 ppm, it was reported that the growth conditions and crop yields improved by more than 30%.

[0017] In this demonstration example, only the CO2 required for photosynthesis was supplied in excess, but fertilizer components normally required for plant cultivation include nitrogen, phosphorus, potassium, and also sulfur, which has recently attracted attention. These fertilizer components are normally thought to be absorbed by plants' roots, but if we focus on the foliar absorption function of nutrients, it is expected that nitrogen and sulfur can be absorbed through the leaves via nitrogen dioxide (NO2) and sulfur dioxide (SO2), for example.

[0018] On the other hand, nitrogen oxides (NOx) and sulfur oxides (SOx) are also known as air pollutants, and in recent years, there has been much discussion about how to reduce these. In particular, at coal-fired power plants, large amounts of nitrogen oxides (NOx), sulfur oxides (SOx), and carbon dioxide (CO2) are produced when coal is burned, and these are released into the atmosphere as exhaust gases. Along with the release of carbon dioxide (CO2), these are often viewed as problematic from the perspective of preventing global warming in recent years. Furthermore, in addition to coal-fired power plants, there are many other factories that similarly emit nitrogen oxides (NOx), sulfur oxides (SOx), and carbon dioxide (CO2).

[0019] The present inventors have focused on the nitrogen oxides (NOx), sulfur oxides (SOx) and carbon dioxide (CO2) thus produced and emitted, and have hypothesized that they may be utilized for foliar absorption by plants.

[0020] First, gas recovery from exhaust gas generated in a thermal power plant that generates electricity by burning fossil fuels will be described. More specifically, gas recovery from exhaust gas generated in a thermal power plant that generates electricity by burning coal will be described.

[0021] As shown in Fig. 1, in a coal-fired power plant, coal stored in a coal yard 11 is transported to a bunker 12 via a conveyor, and the coal supplied to the bunker 12 is supplied to a coal pulverizer 14 via a coal feeder 13. In this coal pulverizer 14, the coal is pulverized into fine particles so that the coal can be efficiently combusted in a downstream boiler 15, and is supplied to the boiler 15.

[0022] The coal supplied to the boiler 15 is burned, and the heat of combustion generates steam, which rotates a turbine 31 to turn a generator 32, generating electricity. The electricity obtained by the power generation is transmitted via a transformer 33 and a switch 34. An air supply pipe 17 connected to a forced draft fan 16 is connected to the boiler 15, and appropriate air is supplied to control the combustion of the coal.

[0023] Coal ash, which is generated as cinders by the combustion of coal in the boiler 15, is successively discharged from the bottom of the boiler 15.

[0024] Exhaust gas is discharged from the boiler 15, which is under higher pressure than the surroundings due to the air supply by the forced draft fan 16, through an exhaust pipe 18. Normally, the exhaust gas is treated by a denitration device 21 and an electric dust collector 22, and further treated by a desulfurization device 24, and then discharged from a chimney 25. An induced draft fan 23 is provided between the electric dust collector 22 and the desulfurization device 24 to induce the exhaust gas.

[0025] In this embodiment, a branch pipe 19 is connected to the exhaust pipe 18 between the boiler 15 and the denitrification device 21, and a gas recovery passage 20 is provided that also guides exhaust gas to this branch pipe 19 side to recover desired gas from the exhaust gas.

[0026] In this gas recovery passage 20, first, a temperature reducing device 26 for lowering the temperature of the exhaust gas is provided, then a harmful substance removing device 40 for removing harmful substances contained in the exhaust gas is provided, and then a compression and sealing machine 27 for sealing the exhaust gas from which harmful substances have been removed into a gas tank is provided. Note that, in the stage preceding the compression and sealing machine 27, a selector for adsorbing and removing gases other than the desired gas may be provided in order to select only the desired gas.

[0027] The deheating device 26 is a heat exchanger that uses cooling water and reduces the temperature of the exhaust gas by bringing the exhaust gas into contact with a cooling pipe through which the cooling water flows. The cooling water that has been heated by heat exchange with the exhaust gas is stored in a hot water tank for generating microbubble water, as described below.

[0028] In this embodiment, the harmful substance removal device 40 is a Venturi scrubber with a cyclone separator as shown in Fig. 2. As shown in Fig. 2(a), the Venturi scrubber is provided with a cylindrical first narrowing wall 41 and a second narrowing wall 42 arranged side by side at a predetermined interval in a direction perpendicular to the exhaust gas flow direction, a cylindrical displacer 43 arranged downstream of the first narrowing wall 41 and the second narrowing wall 42 and parallel to the extension direction of the first narrowing wall 41 and the second narrowing wall 42, and further provided with a shower nozzle body 44 upstream of the first narrowing wall 41 and the second narrowing wall 42 for spraying toward the narrowing walls 41, 42 as shown in Fig. 2(b).

[0029] The displacer 43 is an adjusting body that adjusts the flow velocity of the exhaust gas passing between the first narrowing wall 41 and the second narrowing wall 42. Although not shown, the displacer 43 is provided with an appropriate movable means so that the displacer 43 can move closer to or farther away from the first narrowing wall 41 and the second narrowing wall 42, thereby adjusting the flow velocity of the exhaust gas passing between the first narrowing wall 41 and the second narrowing wall 42.

[0030] The shower nozzle body 44 is equipped with a plurality of spray nozzles that spray the generated microbubble water as described below, and is designed to spray the microbubble water toward the gap formed by the first constriction wall 41 and the second constriction wall 42.

[0031] The microbubble water sprayed by the shower nozzle body 44 contains microbubbles containing gas mainly composed of chlorine gas. This microbubble water is generated by a simplified mechanism of the fine bubble water generating device described in Patent Document 1. Specifically, as described above, the device is equipped with a hot water tank 45 that stores the cooling water that has become hot water, a pressure pump 46 that absorbs the hot water in the hot water tank 45 and pressure-feeds it downstream, and a chlorine gas mixer 47 provided downstream of the pressure pump 46, making it possible to generate microbubble water. A chlorine gas tank 48 containing chlorine gas is connected to the chlorine gas mixer 47 to supply chlorine gas.

[0032] Here, by generating microbubble water from hot water generated in the factory, specifically from hot water generated in the temperature reducing device 26, it is possible to prepare microbubble water suitable for use in a Venturi scrubber without the need to install a heating means for heating the microbubble water. In other words, by generating microbubble water using hot water, the activity of the chlorine contained in the bubbles in the microbubble water can be maintained at a high level when reacting with exhaust gas, as described below, making it easier to promote the reaction with exhaust gas.

[0033] The exhaust gas into which the microbubble water containing chlorine gas has been sprayed in the Venturi scrubber is stirred and mixed with the microbubble water in a cyclone separator 49 provided downstream of the Venturi scrubber.

[0034] The cyclone separator 49 is cylindrical and stretched in the vertical direction, and in particular, a tapered section 51 is provided at the lower side, which is gradually tapered in the vertical downward direction to form a mortar shape, and a dust bunker 52 is provided at the lower end of the tapered section 51. The lower end of the dust bunker 52 serves as a discharge outlet. In the cyclone separator 49, a fluororesin sheet 53 is attached to the inner circumferential surface above the tapered section 51. In FIG. 2(b), reference numeral 54 denotes an inlet for exhaust gas flowing from the venturi scrubber into the cyclone separator 49.

[0035] An exhaust pipe 56 is provided in a ceiling plate 55 provided above the cyclone separator 49, the exhaust pipe 56 penetrating the ceiling plate 55 and having its tip inserted into the cyclone separator. The exhaust pipe 56 in the cyclone separator 49 extends in the vertical direction so as to be concentric with the cylindrical cyclone separator 49.

[0036] The exhaust gas that is mixed and stirred with the microbubble water in the cyclone separator 49 reacts with the chlorine gas in the microbubble water and becomes wet with moisture or water vapor, causing harmful substances contained in the exhaust gas, such as soot and mercury compounds, to settle inside the cyclone separator 49 in the form of powder or an aqueous solution adsorbed or dissolved in moisture.

[0037] In particular, the surface of the fluororesin sheet 53 provided on the inner surface of the cyclone separator 49 is wetted by contact with the microbubble water, and water droplets are generated successively. Therefore, the generated water droplets can wash away the inner surface of the cyclone separator 49, making it easier to guide harmful substances and the like adhering to the inner surface of the cyclone separator 49 to the dust bunker 52 below.

[0038] Meanwhile, gas components such as nitrogen oxides (NOx) and sulfur oxides (SOx) contained in the exhaust gas stirred in the cyclone separator 49 react with chlorine to become nitrogen dioxide (NO2) and sulfur dioxide (SO2) in large amounts, which then flow into the exhaust pipe 56 and are sent downstream together with carbon dioxide (CO2). The gas components sent downstream are sealed in a gas tank by the compression sealer 27.

[0039] The exhaust gas sent downstream from the cyclone separator 49 contains not only nitrogen dioxide and sulfur dioxide, but also carbon dioxide, selenium compounds, boron compounds, etc. In the following, for the sake of convenience, these gases sealed in the gas tank by the compression and sealing machine 27 will be called active ingredient gases.

[0040] Next, a microbubble generating device for producing hollow capsules containing an active ingredient gas will be described.

[0041] 3, the microbubble generator 60 used in this embodiment is provided with a water storage tank 61 and a first pipe 62 having one end connected to the water storage tank 61 and the other end connected to the water storage tank 61 to form a circulation flow path. The first pipe 62 is provided with, from the upstream side, a first pump 63, a first mixer 64-1, a second mixer 64-2, a turbo mixer 65, a microbubble mixer 66, a first mixer 67-1, a second mixer 67-2, and an adjustment mixer 68. The first pipe 62 portion is the bubble generating means of the microbubble generator 60.

[0042] Furthermore, in the microbubble generator 60, a first switching valve 69 is provided in the first pipe 62 downstream of the adjustment mixer 68, and a second pipe 71 is connected to this first switching valve 69 as a branch pipe.

[0043] The second pipe 71 is provided with an electric potential applicator 72, a third mixer 73, a static mixer 74, and a temporary storage tank 75 from the upstream side. Furthermore, a third pipe 77 having a second pump 76 provided in the middle is connected to the temporary storage tank 75, and an adsorption storage container 78 is connected to the downstream side of the second pump 76 of the third pipe 77. A fourth pipe 79 is connected to the adsorption storage container 78, and the downstream end of the fourth pipe 79 is connected to the downstream side of the third mixer 73 of the second pipe 71. The electric potential applicator 72 in the second pipe 71 is the charging means of the microbubble generator 60, the third mixer 73, the static mixer 74, and the temporary storage tank 75 provided in the second pipe 71 are the encapsulation means of the microbubble generator 60, and the adsorption storage container 78 connected to the third pipe 77 is the recovery means of the microbubble generator 60.

[0044] The first mixer 64-1 and the second mixer 64-2 of the first piping 62 are connected in communication with the first air supply pipe 57-1 and the second air supply pipe 57-2, respectively, so that the gas supplied from the first air supply pipe 57-1 to the first mixer 64-1 is mixed with water in the first mixer 64-1, and the gas supplied from the second air supply pipe 57-2 to the second mixer 64-2 is mixed with water in the second mixer 64-2.

[0045] In this embodiment, the first air supply pipe 57-1 and the second air supply pipe 57-2 are pipes branched from the main air supply pipe 57 on the upstream side, and the main air supply pipe 57 is connected to the gas tank via the second switching valve 58. The gas tank is filled with the desired gas to be mixed with water in the first mixer 64-1 and the second mixer 64-2, and in this embodiment, as shown in FIG. 3, a hydrogen gas tank G1 filled with hydrogen gas, an active ingredient gas tank G2 filled with the above-mentioned active ingredient gas, and a gas tank G3 filled with an appropriate gas are connected to the main air supply pipe 57. Each gas tank G1, G2, and G3 are connected to the main air supply pipe 57 via opening and closing valves V1, V2, and V3, respectively, and the gas to be supplied to the first mixer 64-1 and the second mixer 64-2 can be adjusted by opening and closing the opening and closing valves V1, V2, and V3.

[0046] In addition, an air supply pipe 59 that supplies air to the main air supply pipe 57 is connected to the second switching valve 58, making it possible to generate bubble-mixed water that contains air bubbles containing air components. An air supply pump G4 is connected to the air supply pipe 59, and the air is pressure-supplied by this air supply pump G4.

[0047] The water mixed with the desired gas in the first mixer 64-1 and the second mixer 64-2 is stirred and mixed by passing sequentially through the turbo mixer 65 downstream of the first piping 62, the fine bubble mixer 66, the first mixer 67-1, the second mixer 67-2, and the adjustment mixer 68, resulting in water containing at least so-called micron-order bubbles, and the water is then sent to the water storage tank 61.

[0048] The water containing air bubbles sent to the water storage tank 61 is sent to the first pipe 62 by the first pump 63 attached to the first pipe 62, and circulates through the first pipe 62, passing through the first mixer 64-1, the second mixer 64-2, the turbo mixer 65, the fine bubble mixer 66, the first mixer 67-1, the second mixer 67-2, and the adjustment mixer 68 many times, thereby reducing the size of the air bubbles in the water containing air bubbles.

[0049] When the size of the air bubbles in the air-mixed water reaches a desired size, the first switching valve 69 is operated to supply the air-mixed water to the second pipe 71.

[0050] In the electric potential applicator 72 provided in the second pipe 71, the air bubbles in the water containing the air bubbles and fed from the first pipe 62 are charged.

[0051] In the third mixer 73 provided in the second pipe 71, the coating film agent is added to and mixed with the water containing bubbles fed from the electric potential applicator 72, and the mixture is fed to the downstream static mixer 74. A coating film agent supply pipe 73-2 equipped with a flow control valve 73-1 is connected to the third mixer 73, so that an appropriate amount of coating film agent can be supplied. The coating film agent supply pipe 73-2 is connected to a coating film agent storage tank 73-3. As the coating film agent, it is preferable to use a solution mainly composed of various amino acids, for example, glutamic acid.

[0052] In the static mixer 74, the water containing air bubbles and the coating film agent are thoroughly mixed and stirred, so that the air bubbles in the water containing air bubbles are coated with the coating film agent.

[0053] The temporary storage tank 75 stores the water containing air bubbles delivered from the static mixer 74, and hardens the coating film agent that covers the air bubbles in the water containing air bubbles to produce hollow capsules. In the temporary storage tank 75, excess water that exceeds a predetermined amount is drained by overflowing. This is because the hollow capsules are likely to settle in the temporary storage tank 75, and the concentration of hollow capsules in the supernatant water among the water stored in the temporary storage tank 75 becomes extremely low. In other words, the supernatant water, in which the concentration of hollow capsules is extremely low, is drained by overflowing, thereby increasing the storage efficiency of the hollow capsules in the temporary storage tank 75.

[0054] When generating water mixed with bubbles, if hydrogen gas from the hydrogen gas tank G1 is fed to the first mixer 64-1 and the second mixer 64-2 of the first pipe 62, a hydrogen hollow capsule can be generated. Also, when generating water mixed with bubbles, if active ingredient gas from the active ingredient gas tank G2 is fed to the first mixer 64-1 and the second mixer 64-2 of the first pipe 62, an active ingredient hollow capsule can be generated. Also, when generating water mixed with bubbles, if appropriate gas from the gas tank G3 containing appropriate gas is fed to the first mixer 64-1 and the second mixer 64-2 of the first pipe 62, a hollow capsule made of appropriate gas can be generated. Also, when generating water mixed with bubbles, if air fed from the air feed pipe 59 is fed to the first mixer 64-1 and the second mixer 64-2 of the first pipe 62, an air hollow capsule can be generated.

[0055] After the desired hollow capsules are formed in the temporary storage tank 75, the second pump 76 of the third pipe 77 connected to the temporary storage tank 75 is operated to supply the water mixed with the hollow capsules in the temporary storage tank 75 to the adsorption storage vessel 78.

[0056] The hollow capsules in the water mixed with the hollow capsules that are fed to the adsorption storage vessel 78 are charged while in a bubble state by the electric potential applicator 72, and therefore are in a predetermined electric potential state even when they become hollow capsules.

[0057] In the adsorption storage container 78, water containing hollow capsules is passed through the hollow fibers while a buffer solution having a predetermined electric potential is circulated, so that the hollow capsules are attracted to the inner surface of the hollow fibers by electrostatic action. The hollow capsules attracted to the inner surface of the hollow fibers are adsorbed by the mutual surface action of the hollow fibers and the hollow capsules, making it possible to recover the hollow capsules. The remaining water containing hollow capsules after the hollow capsules have been adsorbed and removed by the adsorption storage container 78 is returned to the second pipe 71 via the fourth pipe 79 connected downstream of the adsorption storage container 78.

[0058] The adsorption storage container 78 is intended to be replaced for each type of hollow capsule, and in this embodiment, it can be an adsorption storage container storing hydrogen hollow capsules, an adsorption storage container storing active ingredient hollow capsules, an adsorption storage container storing hollow capsules made of an appropriate gas, or an adsorption storage container storing atmospheric hollow capsules.

[0059] From the adsorption storage container 78 in which the desired hollow capsules are stored, the hollow capsules are peeled off from the hollow fibers by passing an appropriate amount of water through the hollow fibers of the adsorption storage container 78 while vibrating the hollow fibers, making it possible to recover the hollow capsules in a high concentration.

[0060] Specifically, as shown in FIG. 4, a vibration-type extraction device 80 is used to extract and recover hollow capsules from an adsorption storage container 78.

[0061] The vibrating extractor 80 includes a base 81, a support 82 erected on the base 81, a hanging arm 83 extending horizontally from the upper end of the support 82, a water supply bottle 84 hung from the hanging arm 83, an adsorption storage container 78 having one end connected to it via a water supply pipe 85 connected to the lower side of the water supply bottle 84, and a recovery bottle 87 connected to it via a recovery pipe 86 connected to the other end of the adsorption storage container 78. The vibrating extractor 80 further includes an oscillator 88 for applying vibration to the adsorption storage container 78 in the suspended state. The output shaft 88a of the oscillator 88 is attached to the adsorption storage container 78. In FIG. 4, reference numeral 88b denotes a chucking claw provided at the tip of the output shaft 88a of the oscillator 88, and the adsorption storage container 78 is chucked by the chucking claw 88b. The oscillator 88 is connected to a control device 89 for operation control.

[0062] In the adsorption storage container 78, water is passed through the container from the water supply bottle 84 and the container is vibrated by an oscillator 88, thereby causing the hollow capsules adsorbed to the hollow fibers to peel off. The hollow capsules peeled off from the hollow fibers are discharged into a recovery bottle 87 together with the water supplied from the water supply bottle 84. By using the adsorption storage container 78 to recover the hollow capsules, it is possible to produce hollow capsule-containing water that contains hollow capsules at a high concentration.

[0063] In particular, in this embodiment, as shown in Figure 5, it is possible to prepare a hydrogen hollow capsule bottle CB1 containing hollow capsule-containing water containing a high concentration of hydrogen hollow capsules, an active ingredient hollow capsule bottle CB2 containing hollow capsule-containing water containing a high concentration of active ingredient hollow capsules, an appropriate gas hollow capsule bottle CB3 containing water containing hollow capsules containing a high concentration of appropriate gas hollow capsules, and an air hollow capsule bottle CB4 containing water containing hollow capsules containing a high concentration of air hollow capsules.

[0064] The particle size distribution and concentration of the hollow capsules contained in each of these bottles CB1-4 can be made almost the same if the operating conditions of the microbubble generator 60 and the vibration type extraction device 80 are the same. Therefore, by adjusting the amount of extraction from each of the bottles CB1-4, the blending amount of each hollow capsule can be adjusted, and a hollow capsule-containing mixed water with a constant blending state can be obtained. This hollow capsule-containing mixed water is called super functional water.

[0065] This super functional water can be produced by a blending device 90 shown in Fig. 5. This blending device 90 is a super functional water production device.

[0066] The blending device 90 is equipped with a mounting table 91 on which a hydrogen hollow capsule bottle CB1, an active ingredient hollow capsule bottle CB2, an appropriate gas hollow capsule bottle CB3, and an air hollow capsule bottle CB4 can be placed at a predetermined height, and a frame 92 that supports this mounting table 91.

[0067] Each of the bottles CB1-4 is placed on a mounting table 91 with its outlet facing downward, and a measuring bottle 94 is connected to the outlet of each bottle via a connecting pipe 93, so that the hollow capsule-containing mixed water can be fed to each of the measuring bottles 94 by gravity. In FIG. 5, reference numeral 95 denotes a supporting frame that supports each of the measuring bottles 94.

[0068] One end of a supply pipe 96 is connected to the lower end of each measuring bottle 94, and the other end of the supply pipe 96 is connected to a mixed water bottle 97. In this embodiment, the supply pipes 96 connected to the lower end of each measuring bottle 94 are connected at their midpoints and then connected to the mixed water bottle 97, but this connection may or may not be required. In this embodiment, the mixed water bottle 97 is placed on a mixer 98 so that the mixed water containing hollow capsules in the mixed water bottle 97 can be stirred.

[0069] A metering ball valve BV1 is provided in each of the connecting pipes 93 that communicates with each of the bottles CB1-4 and each of the measuring bottles 94. By opening the metering ball valve BV1, the hollow capsule-containing mixed water is fed from each of the bottles CB1-4 to the corresponding measuring bottle 94, and by closing the metering ball valve BV1, the feeding of the hollow capsule-containing mixed water from each of the bottles CB1-4 to the corresponding measuring bottle 94 is stopped.

[0070] A capping ball valve BV2 is also provided in the supply pipe 96 that connects the measuring bottle 94 and the mixed water bottle 97. With the capping ball valve BV2 in a closed state, a predetermined amount of hollow capsule-containing mixed water is supplied from each of the bottles CB1-4 to the measuring bottle 94, and then, by opening the capping ball valve BV2, a predetermined amount of hollow capsule-containing mixed water can be supplied from each of the measuring bottles 94 to the mixed water bottle 97.

[0071] The super functional water produced in this manner is a mixed water containing hollow capsules as described above, and one of the effective ways to use this super functional water is to spray it on the leaves of plants.

[0072] In particular, the inventor originally focused on the function of foliar absorption of nutrients through stomata, and the super functional water of the present invention is formulated to be effective in foliar absorption. In particular, by containing hollow capsules generated from exhaust gas from coal-fired power plants, it is possible to apply not only nitrogen and sulfur components expected as fertilizer components from nitrogen dioxide and sulfur dioxide, but also carbon dioxide, selenium compounds, boron compounds, etc.

[0073] One effective way to spray super functional water onto leaves is to use a drone.

[0074] Specifically, as shown in Fig. 6, a spray liquid tank 101 for storing the super functional water is attached to a drone 100 that can be flown by remote control, and a spray hose 102 is connected in communication with the spray liquid tank 101. Then, while flying the drone 100, the super functional water supplied to the spray hose 102 can be sprayed downward from the drone 100.

[0075] In particular, an electrostatic nozzle 103 is provided at the tip of the spray hose 102. The microcapsules in the super-functional water remain charged to a predetermined potential by the electric potential applicator 72 of the microbubble generator 60, and by spraying the super-functional water using the electrostatic nozzle 103, the super-functional water can be sprayed while being atomized. In Fig. 6, reference numeral 104 denotes a high-voltage generator that supplies a predetermined voltage to the annular electrode of the electrostatic nozzle 103.

[0076] The drone 100 is equipped with a camera 105 that photographs the spraying area, and spraying can be prevented by checking the target of spraying while spraying with this camera 105. In particular, the super functional water of this embodiment contains hollow capsules containing nitrogen dioxide or sulfur dioxide, so that it is possible to prevent unexpected situations from occurring due to spraying to unintended targets.

[0077] The super functional water sprayed onto the leaf surface contains hollow capsules that are themselves electrically charged, and when sprayed from an electrostatic nozzle 103, the hollow capsules are attracted to the leaf surface by electrostatic action.

[0078] The hollow capsules in the super functional water sprayed on the leaf surface are taken into the leaf through the stomata, and the hollow capsules collapse due to the energy of sunlight, releasing nitrogen dioxide, sulfur dioxide, carbon dioxide, etc., from inside the hollow capsules into the leaf. Note that the hollow capsules taken into the leaf do not all collapse at the same time, but rather collapse gradually over a long period of time, making it possible to effectively supply nitrogen dioxide, sulfur dioxide, carbon dioxide, etc.

[0079] The carbon dioxide released into the leaves by the hollow capsules activates photosynthesis and promotes the emission of oxygen, while the fertilizing effect of nitrogen dioxide and sulfur dioxide contributes to improving the productivity and quality of plants. In particular, the promotion of oxygen emission suppresses greenhouse gases and contributes to preventing environmental pollution. In other words, it purifies the air and creates an ideal carbon neutral effect.

[0080] Furthermore, nitrogen oxides (NOx) and sulfur oxides (SOx), which would normally be released as air pollutants, are effectively utilized as nitrogen dioxide and sulfur dioxide, which also contributes to preventing soil pollution caused by nitrogen and sulfur, and environmental pollution caused by greenhouse gases.
