Description

Technical Field

[0001] The present invention relates to a bubble water synthesis system capable of routinely utilizing the energy generated when an ultra-fine bubble (UFB) bursts.

Background Art

[0002] Recently, the inventor of the present application has proposed a piston-type bubble water production apparatus equipped with a syringe-type bubble generator (see Patent Document 1 below). According to this proposed bubble water production apparatus, it is said that it is possible to generate UFBs with an extremely high concentration (for example, 10 billion or more per ml).

[0003] By the way, it is known that UFBs generate free radicals when they burst, and in recent years, it has been expected that the energy generated when they burst can suppress the growth of bacteria and viruses.

[0004] That is, UFBs, which are extremely small fine bubbles, are said to have the potential to attack microorganisms with the free radicals generated by the interaction between their high surface energy and surrounding substances. Therefore, in the future, applications in fields such as purification, sterilization, promotion of oxidation reactions, buoyancy control, and / or medicine are expected.

[0005] Incidentally, the internal pressure of UFBs generally depends on the diameter of the bubbles generated in the solution. UFBs are very small bubbles, and usually their diameter is several μm or less. The internal pressure varies depending on the generation method and environment, etc., but is around 30 atm (atmospheric pressure).

Summary of the Invention

Problems to be Solved by the Invention

[0007] However, UFBs generally have a long lifespan, possess high stability in solution, and can exist without rupturing for an extended period. Therefore, in order to be able to routinely utilize the free radicals generated when a UFB ruptures, a means to forcibly destroy the UFB was necessary.

[0008] The present invention has been made in view of the above, and an object thereof is to provide a bubble water synthesis system capable of forcibly destroying a part of a UFB and routinely utilizing the energy generated when the UFB ruptures.

Means for Solving the Problems

[0009] To achieve the above object, one aspect of the present invention includes a storage tank for storing a solution for generating UFB water, a first bubble generator for generating the UFB water using the solution stored in the storage tank, and a second bubble generator for generating the UFB water using the solution stored in the storage tank, wherein the second bubble generator has a different generation capacity from the first bubble generator when generating the UFB water. By performing the generation of the UFB water by the first bubble generator and the generation of the UFB water by the second bubble generator, a part of the UFBs in the UFB water is eliminated.

Mode for Carrying Out the Invention

[0012] Hereinafter, with reference to the drawings, a bubble water synthesis system according to an embodiment of the present invention will be described. It should be noted that in the present embodiment, the drawings schematically show the outline of the invention and are different from the actual ones.

[0013] Embodiment FIG. 1 shows a configuration example of an ultra-fine bubble (UFB) water synthesis system 1 to which a bubble water synthesis system according to an embodiment of the present invention is applied.

[0014] This UFB water synthesis system 1 includes, for example, as shown in FIG. 1, a storage tank 10 for storing bubble water (solution) BW containing supersaturated water and the like, an ultra-high concentration UFB generation device 100 connected to the storage tank 10 via a water conduit (pipe) 20, and a high concentration UFB generation device 200 connected to the storage tank 10 via a water conduit (pipe) 30.

[0015] In the UFB water synthesis system 1 of this embodiment, the ultra-high concentration UFB generator 100 is, for example, a piston-type bubble water production device, and the limit number of UFBs generated per ml of bubble water BW, which is the production capacity of UFB water, is about several hundred million per ml. On the other hand, the high concentration UFB generator 200 is, for example, a circulation-type UFB generator, and the production capacity (limit number of UFBs generated) of UFB water is about 10% of that of the ultra-high concentration UFB generator 100.

[0016] In such a configuration, in the process of generating bubble water BW (when UFB is generated), for example, when the high concentration UFB generator 200 exceeds its own limit number of generated UFBs, it functions as a UFB elimination device (operates to destroy more UFBs while maintaining the limit number of generated UFBs).

[0017] As the ultra-high concentration UFB generator 100, for example, as shown in FIG. 2, it has a syringe-type UFB generation unit 130, a drive unit 101 that drives the plunger (pusher / piston) 134 of the UFB generation unit 130, and a control unit (control unit) 115 that controls the drive unit 101. The UFB generation unit 130 is, for example, a decompression-type bubble generator, and is composed of a syringe (outer cylinder) 133 formed of stainless steel (SUS), or metal, resin, glass, etc. subjected to fluororesin processing, and a plunger 134 that reciprocates inside the syringe 133.

[0018] Details of the UFB generation unit 130 will be described later.

[0019] The drive unit 101 includes, for example, an electric motor or an air drive mechanism, and also includes a holder unit 110 that supports and fixes the UFB generation unit 130, a fixing unit 111 that fixes the syringe 133 to the holder unit 110, a holding unit 114 that holds the proximal end side of the plunger 134, and a slide unit 112 that slides the holding unit 114 so that the plunger 134 reciprocates in the cylinder direction (the direction of the arrow x in the figure) of the syringe 133.

[0020] The control unit 115 includes, for example, programs for controlling the decompression speed (forward movement speed), the pressurization speed (return movement speed), the position maintenance time (interval time), and the number of times (number of reciprocating movements). Then, based on the setting input of the operator, by controlling (program operation) the drive unit 101 according to the program, it is possible to control the size (bubble particle size) and amount (number of bubbles) of the bubbles generated in the UFB generation unit 130, the time, and so on.

[0021] Here, as the bubble water BW, in addition to the UFB water, in the storage tank 10 where the solution before bubble generation and the intermediate FB (fine bubble) water are mixed, for example, as shown in FIG. 2, at least the tip portion of one water conduit 20a forming the water conduit 20 is immersed in the bubble water BW, and its proximal end portion is connected to the gas-liquid mixing unit portion 123. The other water conduit 20b forming the water conduit 20 has its proximal end portion connected to the gas-liquid mixing unit portion 123, and outside the storage tank 10, the tip portion is connected to the cylinder tip portion of the syringe 133 of the UFB generation unit 130.

[0022] Details will be described later, but the storage tank 10 is connected to a discharge water conduit 30a and a suction water conduit 30b as water conduits 30 leading to the high-concentration UFB generation device 200.

[0023] Further, the storage tank 10 may be configured to include a gas suction portion that sucks in dissolved gas (for example, outside air) from the suction port as a dissolved gas generation portion.

[0024] Details of the gas-liquid mixing unit portion 123 will be described later.

[0025] FIG. 3 is a cross-sectional view showing the schematic configuration of the UFB generation unit 130 in the ultra-high-concentration UFB generation device 100.

[0026] The UFB generation unit 130, which consists of a syringe 133 and a plunger 134, is provided, as shown in FIG. 3 for example, with a gasket 135 provided on the tip side of the plunger 134 so as to have no clearance with the inner diameter of the syringe 133, and a packing member 136 detachably attached to the front side of the gasket 135 by a screw 137 or the like. Due to the multi-layer structure of this gasket 135 and packing member 136, when bubbles are generated, it is possible to suppress the leakage of bubble water BW from exceeding the gasket 135 within the syringe 133. For example, even when introducing ozone gas or the like, it is possible to ensure the safety of the operator.

[0027] A reduced-pressure water suction chamber 138 for taking bubble water BW from the storage tank 10 into the syringe 133 is formed between the packing member 136 and the tip portion of the syringe 133. The volume of this reduced-pressure water suction chamber 138 is changed according to the position of the plunger 134 relative to the syringe 133.

[0028] Here, as the syringe 133, for example, it is desirable to form it such that the inner diameter (diameter) of the cylindrical portion is 15 mm or more, the length (cylinder length) is 50 mm or more, the inner diameter of the cylinder tip portion is 2 mm or more, and the difference between the inner diameter of the cylindrical portion and the inner diameter of the cylinder tip portion is 10 mm or more.

[0029] Also, in the UFB generation unit 130, a liquid acceleration and pressurization unit 131 for accelerating and pressurizing the bubble water BW from the storage tank 10 is provided at the cylinder tip portion of the syringe 133 connected to the other water conduit 20b, for example, by the Venturi effect. This liquid acceleration and pressurization unit 131 is detachably provided on the mounting end side of the half-joint portion 139 with the syringe 133, for example, by an RC connection screw processing technique.

[0030] That is, in this embodiment, it is possible to vary the introduction diameter of the bubble water BW by replacing the liquid acceleration and pressurization unit 131. Thereby, it is possible to change the flow rate of the bubble water BW according to the introduction diameter of the bubble water BW of the liquid acceleration and pressurization unit 131.

[0031] FIG. 4 is a cross-sectional view showing a schematic configuration of a gas-liquid mixing unit portion 123 provided in the middle of the water conduit 20.

[0032] As shown in FIG. 4, for example, the gas-liquid mixing unit portion 123 includes a gas-liquid contact member 125 having gas intake ports (gas introduction paths) 125b and 125c connected to the water conduit 125a, wherein the base end portions of one water conduit 20a and the other water conduit 20b are respectively connected via tube joint connectors 124a and 124b. A gas-liquid flow rate adjusting member 120 is provided movably up and down at the gas intake port 125b of the gas-liquid contact member 125 to take in gas (air or gas) in the storage tank 10 from the gas intake port 125c.

[0033] This gas-liquid mixing unit portion 123 dissolves (mixes) the gas self-aspirated from the gas intake port 125c into the bubble water BW flowing through the water conduit 125a disposed so as to penetrate in the lateral direction, according to the gas-liquid flow rate adjusting member 120.

[0034] That is, the gas-liquid flow rate adjusting member 120 is formed by connecting, for example, special Imoneji (also called a hollow set, etc.) having through passages with different diameters in the vertical direction, and by closing it, the flow rate of the gas taken in from the gas intake port 125c can be adjusted. Further, by changing the degree of protrusion into the water conduit 125a by closing it and changing the flow of the bubble water BW in the water conduit 125a, the particle diameter and the number of bubbles can be adjusted.

[0035] According to the configuration according to the present embodiment, as the UFB water generation ability, an ultra-high concentration UFB generation device 100 can be provided in which the generation limit number of UFBs is about several tens of billions per ml (100 billion per ml or more).

[0036] On the other hand, as the high-concentration UFB generation device 200, for example, as shown in FIG. 2, a multi-stage (for example, two-stage) pressure dissolution type UFB generation device called a circulation type is used. This circulation type UFB generation device 200 is composed of, for example, a UFB generation unit 210 that generates bubble water BW and a gas supply device 220, as shown in FIG. 5.

[0037] The UFB generation unit 210 includes, for example, a first-stage initial pressure dissolution generation tank 213, a second-stage second pressure dissolution generation tank 223, a first-stage pressure dissolution bubble generation nozzle 214, and a second-stage pressure dissolution bubble generation nozzle 216. In addition, this UFB generation unit 210 has a gas-liquid mixing nozzle 219, a gas supply nozzle 222, a gas mixer (gas-liquid mixer) 215, a generation control unit 231, a drive pump 212, and a pump drive unit 211, etc.

[0038] The gas supply device 220 supplies a gas (for example, air or a chemical-resistant gas, etc.) that is a raw material for generating UFBs, which are nano-level fine bubbles, and FBs, which are micro-level fine bubbles, as the bubble target gas, to the UFB generation unit 210. A gas supply nozzle 222 is connected to this gas supply device 220 via a gas supply pipe (gas pipe) 221.

[0039] The gas supply nozzle 222 is for introducing the bubble target gas from the gas supply device 220 from one side surface of the gas mixer 215. In order to make the gas supply ratio, for example, about 5% to 30% of the circulating bubble water BW, the hole diameter of the nozzle port connected to the gas inlet of the gas mixer 215 is set to about 0.3 mmφ.

[0040] In order to enable fine adjustment of the gas supply ratio by the gas supply nozzle 222, a flow meter (not shown) may be provided.

[0041] The gas mixer 215 is for mixing the gas from the gas supply device 220 into a solution (for example, pure water or a chemical-resistant liquid) before bubble generation, and adjusts so that the dissolved gas concentration of the gas to be mixed is within a predetermined value range.

[0042] For example, as shown in FIG. 2, the gas mixer 215 is connected to the deepest part on the side surface of the storage tank 10 through an intake water conduit 30b forming a water conduit 30, and the bubble water BW stored in the storage tank 10 is supplied thereto.

[0043]

[0042] Also, a gas-liquid mixing nozzle 219 is connected to, for example, the upper surface of the gas mixer 215. The hole diameter of the nozzle opening on the suction port side of the drive pump 212 is set to about 3.0 mmφ so that the gas-liquid mixing nozzle 219 does not cause resistance when the drive pump 212 sucks the bubble water BW (in the decompression precipitation state).

[0044] The gas-liquid mixing nozzle 219 has a spherical plug member 219a that can float up and down, and a stopper member 219b that restricts the movement (lifting) of the plug member 219a in the direction of the nozzle opening connected to the drive pump 212. By this plug member 219a, when the drive pump 212 discharges the bubble water BW (in the pressurized dissolution state), the water injection port on the gas mixer 215 side is blocked so as to prevent the backflow of the bubble water BW to the gas mixer 215 side. Conversely, when the drive pump 212 sucks the bubble water BW (in the decompression precipitation state), the water injection port on the gas mixer 215 side is opened.

[0045] For example, as shown in FIGS. 6(a) and 6(b), the drive pump 212 has a diaphragm pump (also referred to as a diaphragm pump) structure. The volume inside the chamber 212d of the drive pump 212 is made variable by the pump drive unit 211, so that the suction / discharge operation (pump operation) of the bubble water BW is performed.

[0046]

[0043] That is, when the volume of the chamber 212d of the drive pump 212 is expanded, a decompression precipitation state (during suction) is achieved, and when the volume is reduced corresponding to the restoration to the original state, a pressurized dissolution state (during discharge) is achieved.

[0047] Here, referring to FIG. 6, the operation of the drive pump 212 will be described. Note that FIG. 6(a) is a schematic cross-sectional view in the reduced-pressure deposition state, and FIG. 6(b) is a schematic cross-sectional view in the pressurized dissolution state.

[0048] As shown in FIGS. 6(a) and 6(b) for example, the drive pump 212 includes a cylindrical chamber main body portion 212a having a suction port and a discharge port, a chamber variable portion 212b provided so as to close the opening portion of the chamber main body portion 212a, and a chamber operation portion 212c that operates (deforms) the chamber variable portion 212b.

[0049] In the drive pump 212, the nozzle port of the gas-liquid mixing nozzle 219 is connected to the suction port of the chamber main body portion 212a, and the injection port of the generation control unit 231 is connected to the discharge port.

[0050] The chamber variable portion 212b keeps the inside of the chamber 212d in a sealed state, and is capable of changing the volume of the inside of the chamber 212d by being deformed into a convex shape or a concave shape (flat shape) according to the operation of the pump drive portion 211. This chamber variable portion 212b is formed of, for example, a resin member made of silicon, a resin member subjected to fluororesin processing, or a thin metal plate having flexibility that can be deformed into a concave shape or a convex shape.

[0051] As shown in FIG. 6(a) for example, in the drive pump 212, when the chamber operation portion 212c is pulled in the direction of arrow Xa in the figure by the pump drive portion 211, the chamber variable portion 212b is curved into a convex shape so as to expand. As a result, as the volume inside the chamber 212d increases by an amount of variable volume 212e corresponding to the variable amount (about 6 ml), the inside of the drive pump 212 is set to the reduced-pressure deposition state.

[0052] Conversely, for example, as shown in Fig. 6(b), when the chamber operation part 212c is pushed in the direction of arrow Xb in the figure by the pump drive part 211, the chamber variable part 212b shrinks into a concave shape so as to return to its original state (restore to the original state). As a result, as the volume of the inside of the chamber 212d decreases by the variable volume amount 212e and returns to the original state, the inside of the drive pump 212 is brought into a pressure dissolution state.

[0053] That is, by alternately repeating the reduced pressure precipitation state and the pressure dissolution state, at the time of the reduced pressure precipitation state, bubble water BW also flows into the portion where the volume has increased due to the deformation of the chamber variable part 212b (variable volume amount 212e). Along with this, the dissolved gas concentration in the bubble water BW in the drive pump 212 is increased, and raw materials for generating bubble water BW containing UFB of nano level or more are mass-produced.

[0054] Further, at the time of the pressure dissolution state, each time the bubble water BW passes through the first-stage pressure dissolution bubble generation nozzles 214 and the second-stage pressure dissolution bubble generation nozzles 216, which will be described later, a larger amount of bubble water BW is generated step by step, and the number of generated bubbles is sequentially increased (plus).

[0055] In this embodiment, at least the portion in contact with the bubble water BW may be formed using a material such as a fluororesin, a silicone resin, or vinyl chloride that can also cope with an organic solvent or the like. Alternatively, it is also possible to form using a material that can cope with an acid such as stainless steel (SUS).

[0056] With such a configuration, bubble water BW can be generated at a pressure within the range of about 0.1 Mpa to 0.5 Mpa.

[0057] In the UFB generation part 210 shown in Fig. 5, a water injection port of the generation control part 231 is provided at the discharge port of the drive pump 212. This generation control part 231 is for controlling the backflow of the bubble water BW from the side of the first-stage pressure dissolution bubble generation nozzles 214 to the side of the drive pump 212 at the time of the reduced pressure precipitation state.

[0058] That is, the generation control unit 231 has, for example, a spherical plug member 231a that can float and sink, and a stopper member 231b that restricts the movement (lifting) of the plug member 231a in the lateral direction of the primary pressure dissolution bubble generation nozzle 214. By this plug member 231a, when in the reduced pressure precipitation state, the water injection port of the generation control unit 231 on the discharge port side of the drive pump 212 is blocked (the drain port of the generation control unit 231 is in an open state). Conversely, when in the pressure dissolution state, the water injection port of the generation control unit 231 on the discharge port side of the drive pump 212 is opened without blocking the drain port of the generation control unit 231.

[0059] The primary pressure dissolution bubble generation nozzle 214 is for generating finer bubbles by allowing the bubble water BW from the generation control unit 231 to pass through. This primary pressure dissolution bubble generation nozzle 214 has a nozzle port 214a with an aperture diameter (about 2.0 mmφ) substantially the same as that of the nozzle port 216a of the secondary pressure dissolution bubble generation nozzle 216, which will be described later.

[0060] In the primary pressure dissolution generation tank 213, when the bubble water BW passes through the nozzle port 214a of the primary pressure dissolution bubble generation nozzle 214, further generation (refinement / high concentration) of the bubble water BW in the first-stage pressure dissolution state is performed. This primary pressure dissolution generation tank 213 may have, for example, a volume (about 6 ml or so) equal to or greater than the variable volume of the drive pump 212, that is, it may have a volume at least the same as the variable volume amount 212e of the drive pump 212.

[0061] Connected to the primary pressure dissolution generation tank 213 in series with the primary pressure dissolution bubble generation nozzle 214 is a secondary pressure dissolution bubble generation nozzle 216. This secondary pressure dissolution bubble generation nozzle 216 is for generating (producing) finer bubbles by allowing the bubble water BW in the primary pressure dissolution generation tank 213 to pass through. The secondary pressure dissolution bubble generation nozzle 216 has a nozzle port 216a with an aperture diameter substantially the same as that of the primary pressure dissolution bubble generation nozzle 214 (for example, the diameter difference is within ±20%).

[0062] The nozzle opening 216a of the two-stage pressure dissolution bubble generation nozzle 216 is connected to the vicinity of the upper surface portion on the side surface of the storage tank 10 via the two-stage pressure dissolution production tank 223 and the discharge conduit 30a forming the water conduit 30, as shown in FIG. 2 for example. By passing the bubble water BW through the nozzle opening 216a of the two-stage pressure dissolution bubble generation nozzle 216 and the two-stage pressure dissolution production tank 223, further generation of the bubble water BW in the second-stage pressure dissolution state is performed.

[0063] Also, in the two-stage pressure dissolution production tank 223, temporary storage of the generated bubble water BW is performed. Thereafter, the temporarily stored bubble water BW is sent to the storage tank 10 by the discharge conduit 30a and stored therein. As the two-stage pressure dissolution production tank 223, for example, any tank having a volume at least the same as the variable volume 212e of the drive pump 212 may be used.

[0064] According to the configuration according to the present embodiment, as the UFB water generation ability, a high-concentration UFB generation device 200 can be provided in which the UFB generation limit number is about 2 billion pieces / ml (about 10% of the UFB water generation ability by the ultra-high concentration UFB generation device 100).

[0065] FIG. 7 illustrates measurement data of the bubble water BW generated by the ultra-high concentration UFB generation device 100 by a nanoparticle analysis system (NANOSIGHT).

[0066] In FIG. 7, the graph on the left side shows the results of the experiment (for example, five times), and the graph on the right side shows the average value. In both cases, the vertical axis represents the FTLA concentration (particles / ml), and the horizontal axis represents the particle size (nm).

[0067] Note that FIG. 7 shows the results when, in the generation of the bubble water BW, the UFB water generation conditions are such that the amount of pure water (WE200) as a solution is 100 ml, the generation time is 60 minutes, the number of driving times of the plunger 134 is 1200 St, and the supply amount of oxygen in the storage tank 10 is 0.05 ml.

[0068] As is also apparent from FIG. 7, according to the ultra-high concentration UFB generator 100, it was confirmed that, for example, bubble water BW containing UFB having a peak in particle size per 100 nm at a ratio of 114e+008 pieces / ml can be generated at an ultra-high concentration.

[0069] Disappearance experiment The results of the disappearance experiment of UFB in the UFB water synthesis system 1 according to the present embodiment will be described below.

[0070] FIG. 8 illustrates measurement data by a nanoparticle analysis system of bubble water BW when the ultra-high concentration UFB generator 100 and the high concentration UFB generator 200 are simultaneously operated in the UFB water synthesis system 1 according to the present embodiment.

[0071] In FIG. 8, the left graph shows the results of the disappearance experiment (for example, five times), and the right graph shows the average value. In both cases, the vertical axis represents the FTLA concentration (particles / ml), and the horizontal axis represents the particle size (nm).

[0072] Note that FIG. 8 shows the results when, in the generation of bubble water BW, the generation conditions of UFB water are such that the amount of pure water (WE200) as a solution is 100 ml, the generation time is 60 minutes, and the supply amount of oxygen in the storage tank 10 is 0.05 ml. Also, the generation conditions of UFB water by the ultra-high concentration UFB generator 100 are the same as those in the case of FIG. 7 (the number of driving times of the plunger 134 is 1200 St).

[0073] As is also apparent from FIG. 8, according to the UFB water synthesis system 1 according to the present embodiment, it was confirmed that, for example, bubble water BW containing UFB having a peak in particle size per 100 nm at a ratio of 60.4e+008 pieces / ml can be generated at a high concentration. That is, in the storage tank 10, the UFB generated by the ultra-high concentration UFB generator 100 and the high concentration UFB generator 200 in 60 minutes decreased (disappeared) by more than 5.36 billion pieces / ml compared to the case where bubble water BW is generated only by the ultra-high concentration UFB generator 100 as shown in FIG. 7, for example.

[0074] Such a phenomenon is presumably caused by the fact that, for example, the limit number of UFBs generated by the high-concentration UFB generator 200 is about 20 billion / ml. When this limit is exceeded, the UFBs with a number of 100 billion / ml or more generated by the ultra-high-concentration UFB generator 100 can no longer be maintained.

[0075] That is, in the UFB water synthesis system 1 according to the present embodiment, by operating the ultra-high-concentration UFB generator 100 and the high-concentration UFB generator 200 simultaneously, a phenomenon such as the disappearance of UFBs due to saturation while maintaining the limit number of UFBs generated by the high-concentration UFB generator 200 itself is utilized. As a result, according to the UFB water synthesis system 1 according to the present embodiment, it becomes possible to simultaneously achieve the generation of a large amount of UFBs and the active reduction of UFBs. Therefore, a part of the UFBs can be forcibly destroyed, and the free radicals (energy at the time of rupture) generated at the time of their rupture can be utilized daily. That is, the bubble water BW thus generated can be freely used in various applications (fields) such as purification, sterilization, promotion of oxidation reaction, buoyancy control, and / or medical treatment in a timely manner.

[0076] Finally, when the generation efficiency (generation capacity) of the UFB generator is different, we will consider the factors of the phenomenon that the excessively generated UFBs disappear and the number of bubbles decreases to the extent of the generation number of the UFB generator with low generation efficiency.

[0077] Regarding the changes in pressure and solubility, it is presumed that the internal pressure of the high-concentration UFB generator is lower than that of the ultra-high-concentration UFB generator, so the solubility of UFBs in the bubble water tends to decrease, leading to the disappearance of bubbles.

[0078] Also, when comparing the high-concentration UFB generator and the ultra-high-concentration UFB generator, it is considered that the cavitation in the high-concentration UFB generator is insufficient, so the existing UFBs cannot maintain stability and disappear. Cavitation plays an important role in the generation and stabilization of bubbles.

[0079] As described above, according to the present embodiment, a part of the UFB can be forcibly destroyed, and the free radicals generated when the UFB ruptures can be used daily.

[0080] That is, the ultra-high-concentration UFB generation device 100 and the high-concentration UFB generation device 200 with different UFB generation limit numbers are combined, and the combined ultra-high-concentration UFB generation device 100 and high-concentration UFB generation device 200 are operated simultaneously. Thereby, it is possible to actively reduce more UFB while maintaining the UFB generation limit number by the high-concentration UFB generation device 200. Therefore, the free radicals generated when the UFB ruptures can be easily used for reaction promotion and the like on a daily basis.

[0081] Note that the ultra-high-concentration UFB generation device 100 is not limited to a piston-type bubble water production device, and the high-concentration UFB generation device 200 is not limited to a circulation-type UFB generation device, especially a multi-stage pressure dissolution type UFB generation device.

[0082] As described above, several embodiments have been exemplified to explain the aspects of the present invention. However, each embodiment is an example, and the scope of the invention described in the claims can be variously modified without departing from the gist of the invention.
