Description

Technical Field

[0001] The present invention relates to a bubble water synthesis system that can routinely utilize the energy when an ultra-fine bubble (UFB) bursts.

Background Art

[0002] Recently, the inventors of the present application have proposed a piston-type bubble water production device equipped with a syringe-type bubble generator (see Patent Document 1 below). According to this proposed bubble water production device, it is said that it is possible to generate UFBs of an ultra-high concentration (for example, 100 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 is expected that the energy when they burst can suppress the growth of bacteria and viruses.

[0004] That is, UFBs, which are extremely small microbubbles, are said to generate free radicals that may attack microorganisms due to the high surface energy and the interaction with 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 it 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 long periods. Therefore, in order to routinely utilize the free radicals generated when UFBs rupture, a means of forcibly destroying UFBs was necessary.

[0008] The present invention has been made in view of the above, and its object is to provide a bubble water synthesis system that can forcibly destroy a portion of the UFB and make it possible to routinely utilize the energy generated when the UFB bursts. [Means for solving the problem]

[0009] To achieve the above objectives, one aspect of the present invention comprises a storage tank for storing a solution for generating UFB water, a first bubble generating device for generating UFB water using the solution stored in the storage tank, and a second bubble generating device for generating UFB water using the solution stored in the storage tank, the second bubble generating device having a different generation capacity for generating UFB water than the first bubble generating device, wherein the generation of UFB water by the first bubble generating device and the generation of UFB water by the second bubble generating device eliminates a portion of the UFB in the UFB water. [Effects of the Invention]

[0010] According to the present invention, it is possible to provide a bubble water synthesis system that can forcibly destroy a portion of the UFB and utilize the energy generated when the UFB bursts on a daily basis. [Brief explanation of the drawing]

[Figure 8] This example illustrates bubble water measurement data when the ultra-high concentration UFB generator and the high concentration UFB generator are driven simultaneously in the UFB water synthesis system according to this embodiment. [Modes for carrying out the invention]

[0012] The bubble water synthesis system according to an embodiment of the present invention will be described below with reference to the drawings. It should be noted that in this embodiment, the drawings are schematic representations of the invention and may differ from the actual system.

[0013] Embodiment Figure 1 shows an example of the configuration of an ultrafine bubble (UFB) water synthesis system 1 to which the bubble water synthesis system according to an embodiment of the present invention is applied.

[0014] As shown in Figure 1, for example, this UFB water synthesis system 1 includes a storage tank 10 for storing bubble water (solution) BW containing supersaturated water, an ultra-high concentration UFB generator 100 connected to the storage tank 10 via a water conduit (piping) 20, and a high concentration UFB generator 200 connected to the storage tank 10 via a water conduit (piping) 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 1 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 UFBs are 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 within the syringe 133.

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

[0019] The drive unit 101 is equipped with, for example, an electric motor or an air drive mechanism, and also has 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 (arrow x direction in the figure) of the syringe 133.

[0020] The control unit 115 includes, for example, programs for controlling the depressurization speed (forward movement speed), pressurization speed (return movement speed), position maintenance time (interval time), and number of cycles (number of reciprocating movements). Based on the operator's input settings, the drive unit 101 is controlled according to the program (program operation), making it possible to control the size (bubble particle size), quantity (number of bubbles), and duration of the bubbles generated by the UFB generation unit 130.

[0021] Here, in the storage tank 10, where bubble water BW is a mixture of UFB water, the solution before bubble generation, and intermediate FB (fine bubble) water, for example, as shown in Figure 2, at least the tip portion of one of the water conduits 20a that make up the water conduit 20 is immersed in the bubble water BW, and its base portion is connected to the gas-liquid mixing unit 123. The base portion of the other water conduit 20b that makes up the water conduit 20 is connected to the gas-liquid mixing unit 123, and outside the storage tank 10, its tip portion is connected to the nozzle portion of the syringe 133 of the UFB generation unit 130.

[0022] As will be explained in more detail later, the storage tank 10 is connected to a discharge pipe 30a and an intake pipe 30b, which serve as a water conduit 30 leading to the high-concentration UFB generation device 200.

[0023] Furthermore, the storage tank 10 may be configured to include a gas intake section that draws in dissolved gas (for example, outside air) from an inlet, which serves as a dissolved gas generation section.

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

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

[0026] The UFB generating unit 130, consisting of a syringe 133 and a plunger 134, has, for example as shown in Figure 3, a gasket 135 provided on the tip side of the plunger 134 so as to have no gap between it and the inner diameter of the syringe 133, and a packing member 136 attached to the front side of the gasket 135 in a replaceable manner by a screw 137 or the like. This multi-layered structure of the gasket 135 and packing member 136 suppresses the leakage of bubble water BW beyond the gasket 135 inside the syringe 133 when bubbles are generated, and ensures the safety of the operator, for example, when introducing ozone gas.

[0027] A depressurized water intake chamber 138 is formed between the packing member 136 and the tip of the syringe 133, which takes in bubble water BW from the storage tank 10 into the syringe 133. The volume of this depressurized water intake chamber 138 changes depending on the position of the plunger 134 relative to the syringe 133.

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

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

[0030] In other words, in this embodiment, the introduction diameter of the bubble water BW can be changed by replacing the liquid acceleration pressurization unit 131. This makes it possible to change the flow velocity of the bubble water BW according to the introduction diameter of the bubble water BW in the liquid acceleration pressurization unit 131.

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

[0032] The gas-liquid mixing unit 123 consists of, for example, as shown in Figure 4, a gas-liquid contact member 125 having gas intake ports (gas introduction channels) 125b and 125c connected to the gas intake port 125a, and a gas-liquid flow velocity adjusting member 120 which is provided so as to be vertically movable at the gas intake port 125b of the gas-liquid contact member 125 and takes in gas (air or gas) from the storage tank 10 through the gas intake port 125c.

[0033] This gas-liquid mixing unit 123, in accordance with the gas-liquid flow rate adjustment member 120, dissolves (mixes) the gas that has been self-inhaled from the gas intake port 125c into the bubble water BW flowing through the water conduit 125a, which is arranged to penetrate horizontally.

[0034] In other words, the gas-liquid flow velocity adjusting member 120 is made up of, for example, special grub screws (also called set screws) having through passages of different diameters in the vertical direction, and by tightening them, it is possible to adjust the flow velocity of the gas taken in from the gas intake port 125c. Furthermore, by changing the degree of protrusion into the water conduit 125a by tightening them, the flow of bubble water BW in the water conduit 125a can be changed, thereby adjusting the size and number of bubbles.

[0035] According to the configuration of this embodiment, the ultra-high concentration UFB generating device 100 can be configured such that the maximum number of UFBs that can be generated is approximately several tens of billions / ml (10 billion / ml or more).

[0036] In contrast, the high-concentration UFB generator 200 is a multi-stage (e.g., two-stage) pressurized dissolution type UFB generator, known as a circulating type, as shown in Figure 2. This circulating type UFB generator 200 consists of a UFB generating unit 210 that generates bubble water BW and a gas supply device 220, as shown in Figure 5.

[0037] The UFB generation unit 210 includes, for example, a first-stage pressurized dissolution generation tank 213, a second-stage pressurized dissolution generation tank 223, a first-stage pressurized dissolution bubble generation nozzle 214, and a second-stage pressurized dissolution bubble generation nozzle 216. The UFB generation unit 210 also includes 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.

[0038] The gas supply device 220 supplies the UFB generation unit 210 with gases (for example, air or chemical-resistant gases) that serve as raw materials for generating nano-level microbubbles (UFB) and micro-level microbubbles (FB), which are the target gases for bubble generation. 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 into the gas mixer 215 from one side. The diameter of the nozzle opening connected to the gas inlet of the gas mixer 215 is set to approximately 0.3 mmφ so that the gas supply ratio is, for example, about 5% to 30% of the circulating bubble water BW.

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

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

[0042] The gas mixer 215 is connected to the deepest part of the side of the storage tank 10 via an intake water conduit 30b that forms a water conduit 30, as shown in Figure 2, for example, and is supplied with bubble water BW stored in the storage tank 10.

[0043] Furthermore, a gas-liquid mixing nozzle 219 is connected to, for example, the top surface of the gas mixer 215. The diameter of the nozzle opening on the suction side of the drive pump 212 is approximately 3.0 mmφ so as not to create resistance when the drive pump 212 draws in bubble water BW (in a reduced pressure deposition state).

[0044] The gas-liquid mixing nozzle 219 has a spherical stopper member 219a that can float and sink, and a stopper member 219b that restricts the movement (floating) of the stopper member 219a toward the nozzle opening connected to the drive pump 212. When the bubble water BW is being drained from the drive pump 212 (pressurized dissolution state), the stopper member 219a closes the water inlet on the gas mixer 215 side to prevent backflow of the bubble water BW toward the gas mixer 215 side. Conversely, when the bubble water BW is being drawn in by the drive pump 212 (reduced pressure deposition state), the water inlet on the gas mixer 215 side is opened.

[0045] The drive pump 212 has a diaphragm pump structure, as shown in Figures 6(a) and 6(b), for example. The volume of the chamber 212d inside the drive pump 212 is varied by the pump drive unit 211, thereby enabling the suction / drainage operation (pump operation) of the bubble water BW.

[0046] In other words, the volume of the chamber 212d inside the drive pump 212 is expanded, resulting in a reduced-pressure precipitation state (during water intake), and the volume is reduced, corresponding to returning to the original state, resulting in a pressurized dissolution state (during drainage).

[0047] Now, with reference to Figure 6, the operation of the drive pump 212 will be explained. Figure (a) is a schematic cross-sectional view during the reduced-pressure precipitation state, and Figure (b) is a schematic cross-sectional view during the pressurized dissolution state.

[0048] The drive pump 212 is composed of, for example, a cylindrical chamber body 212a having an inlet and an outlet, a chamber variable part 212b provided to close the opening of the chamber body 212a, and a chamber operating part 212c that operates (deforms) the chamber variable part 212b, as shown in Figures 6(a) and 6(b).

[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 body 212a, and the inlet port of the generation control unit 231 is connected to the discharge port.

[0050] The chamber variable section 212b maintains a sealed state inside the chamber 212d and is capable of changing the volume inside the chamber 212d by deforming into a convex or concave (flat) shape in accordance with the operation of the pump drive unit 211. This chamber variable section 212b is formed from a material that can be deformed into a concave or convex shape, such as a silicone resin member, a resin member with a fluororesin coating, or a flexible metal sheet.

[0051] As shown in Figure 6(a), for example, the chamber operating part 212c of the drive pump 212 is pulled in the direction of the arrow Xa by the pump drive unit 211, causing the chamber variable part 212b to be curved into a convex shape so that it expands. As a result, the volume of the inside of the chamber 212d increases by the amount of the variable volume 212e corresponding to the variable amount (approximately 6 ml), and the inside of the drive pump 212 is subjected to a reduced pressure deposition state.

[0052] Conversely, as shown in Figure 6(b), for example, when the chamber operating part 212c is pushed in the direction of the arrow Xb by the pump drive unit 211, the chamber variable part 212b collapses into a concave shape, returning to its original state. As a result, the volume of the chamber interior 212d is reduced by the amount of the variable volume 212e and returns to its original state, and the inside of the drive pump 212 is brought into a pressurized melting state.

[0053] In other words, as the vacuum precipitation state and the pressurized dissolution state are repeated alternately, during the vacuum precipitation state, bubble water BW flows into the portion (variable volume 212e) whose volume has increased due to the deformation of the variable chamber section 212b. Consequently, the dissolved gas concentration in the bubble water BW in the drive pump 212 increases, and raw materials for generating bubble water BW containing UFB at the nano level or higher are mass-produced.

[0054] Furthermore, in the pressurized dissolution state, each time the bubble water BW passes through the first-stage pressurized dissolution bubble generation nozzle 214 and the second-stage pressurized dissolution bubble generation nozzle 216, as described later, a larger amount of bubble water BW is generated in stages, and the number of bubbles generated is successively increased.

[0055] In this embodiment, at least the portion that comes into contact with the bubble water BW may be formed using a material that can withstand organic solvents, such as fluororesin, silicone resin, or PVC. Alternatively, it may be formed using an acid-resistant material such as stainless steel (SUS).

[0056] With this configuration, bubble water (BW) can be generated at a pressure within the range of approximately 0.1 MPa to 0.5 MPa.

[0057] In the UFB generation unit 210 shown in Figure 5, the discharge port of the drive pump 212 is provided with an inlet for the generation control unit 231. This generation control unit 231 is for controlling the backflow of bubble water BW from the first-stage pressurized dissolution bubble generation nozzle 214 to the drive pump 212 during the reduced-pressure precipitation state.

[0058] Specifically, the generation control unit 231 includes, for example, a spherical stopper member 231a that can float and sink, and a stopper member 231b that restricts the movement (floating) of the stopper member 231a toward the first-stage pressurized dissolution bubble generation nozzle 214. This stopper member 231a closes the water inlet of the generation control unit 231 on the discharge side of the drive pump 212 when in a reduced-pressure deposition state (the drain port of the generation control unit 231 remains open). Conversely, when in a pressurized dissolution state, the water inlet of the generation control unit 231 on the discharge side of the drive pump 212 is opened without closing the drain port of the generation control unit 231.

[0059] The first-stage pressurized dissolution bubble generation nozzle 214 is designed to generate finer bubbles by passing the bubble water BW from the generation control unit 231 through it. This first-stage pressurized dissolution bubble generation nozzle 214 has a nozzle opening 214a with approximately the same hole diameter (about 2.0 mmφ) as the nozzle opening 216a of the second-stage pressurized dissolution bubble generation nozzle 216, which will be described later.

[0060] In the first-stage pressurized dissolution generation tank 213, bubble water BW is further generated (micronized / high-concentrated) in the first-stage pressurized dissolution state as it passes through the nozzle opening 214a of the first-stage pressurized dissolution bubble generation nozzle 214. For example, the volume of this first-stage pressurized dissolution generation tank 213 (approximately 6 ml) should be equal to or greater than the variable volume of the drive pump 212, that is, it should have at least the same volume as the variable volume 212e of the drive pump 212.

[0061] The first-stage pressurized dissolution generation tank 213 has a second-stage pressurized dissolution bubble generation nozzle 216 connected in series with the first-stage pressurized dissolution bubble generation nozzle 214. This second-stage pressurized dissolution bubble generation nozzle 216 is used to generate (create) finer bubbles by passing the bubble water BW in the first-stage pressurized dissolution generation tank 213 through it. The second-stage pressurized dissolution bubble generation nozzle 216 has a nozzle opening 216a with approximately the same hole diameter as the first-stage pressurized dissolution bubble generation nozzle 214 (for example, a diameter difference of ±20% or less).

[0062] The nozzle opening 216a of the two-stage pressurized dissolution bubble generation nozzle 216 is connected to the upper side of the storage tank 10 via a discharge pipe 30a that forms a two-stage pressurized dissolution generation tank 223 and a water conduit 30, as shown in Figure 2, for example. As the bubble water BW passes through the nozzle opening 216a of the two-stage pressurized dissolution bubble generation nozzle 216 and the two-stage pressurized dissolution generation tank 223, further generation of bubble water BW occurs in the second stage of pressurized dissolution.

[0063] Furthermore, the generated bubble water BW is temporarily stored in the two-stage pressurized dissolution generation tank 223. The temporarily stored bubble water BW is then sent to the storage tank 10 via the discharge conduit 30a and stored there. The two-stage pressurized dissolution generation tank 223 can be, for example, one that has at least the same volume as the variable volume 212e of the drive pump 212.

[0064] According to the configuration of this embodiment, the high-concentration UFB generator 200 can be configured such that the maximum number of UFBs that can be generated is approximately 2 billion / ml (about 10% of the UFB water generation capacity of the ultra-high-concentration UFB generator 100).

[0065] Figure 7 shows an example of measurement data obtained by a nanoparticle analysis system (NANOSIGHT) for bubble water BW generated by the ultra-high concentration UFB generation device 100.

[0066] In Figure 7, the graph on the left shows the experimental results (for example, five trials), and the graph on the right shows the average value. In both graphs, the vertical axis represents FTLA concentration (particles / ml), and the horizontal axis represents particle size (nm).

[0067] Figure 7 shows the results when the conditions for generating UFB water (Bubble Water BW) were set to 100 ml of pure water (WE200) as a solution, 60 minutes for generation, 1200 St for the plunger 134, and 0.05 ml of oxygen supplied to the storage tank 10.

[0068] As is clear from Figure 7, it was confirmed that the ultra-high concentration UFB generator 100 can produce bubble water BW containing, for example, UFBs with a particle size peak per 100 nm at an ultra-high concentration of 114e+008 particles / ml.

[0069] Disappearance Experiment The following describes the results of an experiment on the elimination of UFB in the UFB water synthesis system 1 according to this embodiment.

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

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

[0072] Figure 8 shows the results when the conditions for generating UFB water (Bubble Water BW) were set to 100 ml of pure water (WE200) as the solution, a generation time of 60 minutes, and an oxygen supply of 0.05 ml in the storage tank 10. The conditions for generating UFB water using the ultra-high concentration UFB generator 100 were the same as in Figure 7 (1200 St of plunger 134).

[0073] As is clear from Figure 8, it was confirmed that the UFB water synthesis system 1 according to this embodiment can produce bubble water BW containing a high concentration of UFBs, for example, 60.4e+008 per ml, each having a particle size peak per 100 nm. In other words, the amount of UFBs generated in the storage tank 10 over 60 minutes by the ultra-high concentration UFB generator 100 and the high concentration UFB generator 200 decreased (disappeared) by more than 5.36 billion per ml compared to when bubble water BW is produced using only the ultra-high concentration UFB generator 100, as shown in Figure 7.

[0074] This phenomenon is presumed to have occurred because, for example, the high-concentration UFB generator 200 has a UFB production limit of approximately 2 billion particles / ml, and once this limit is exceeded, it becomes impossible to maintain the production of tens of billions of UFB particles / ml or more by the ultra-high-concentration UFB generator 100.

[0075] In other words, in the UFB water synthesis system 1 according to this embodiment, by operating the ultra-high concentration UFB generator 100 and the high concentration UFB generator 200 simultaneously, the system utilizes the phenomenon of UFB disappearance due to saturation while maintaining the UFB generation limit of the high concentration UFB generator 200. As a result, the UFB water synthesis system 1 according to this embodiment can simultaneously achieve the generation of a large amount of UFB and the active reduction of UFB. Therefore, a portion of the UFB can be forcibly destroyed, and the free radicals (energy at the time of rupture) generated during their rupture can be utilized on a daily basis. In other words, the bubble water BW thus produced can be freely used as needed for various applications (fields) such as purification, sterilization, promotion of oxidation reactions, buoyancy control, and / or medical use.

[0076] Finally, we will consider the factors behind the phenomenon where, when UFB generators have different generation efficiencies (generation capabilities), excess UFBs disappear, and the number of bubbles decreases to approximately the level produced by the less efficient UFB generator.

[0077] Regarding the changes in pressure and solubility, it is presumed that the internal pressure of a high-concentration UFB generator is lower than that of an ultra-high-concentration UFB generator, which makes it easier for the solubility of UFB in the bubble water to decrease, leading to the collapse of bubbles.

[0078] Furthermore, when comparing a high-concentration UFB generator with an ultra-high-concentration UFB generator, it is believed that the cavitation generated by the high-concentration UFB generator is insufficient, causing existing UFBs to lose stability and disappear. Cavitation plays an important role in the generation and stabilization of bubbles.

[0079] As described above, according to this embodiment, a portion of the UFB can be forcibly destroyed, and the free radicals generated when the UFB ruptures can be utilized on a daily basis.

[0080] Specifically, a super-high concentration UFB generator 100 and a high-concentration UFB generator 200, each with different UFB generation limits, are combined, and the combined super-high concentration UFB generator 100 and high-concentration UFB generator 200 are operated simultaneously. This makes it possible to actively reduce UFBs beyond the generation limit of the high-concentration UFB generator 200 while maintaining that limit. Consequently, the free radicals generated when UFBs burst can be easily utilized on a regular basis for reaction acceleration and other purposes.

[0081] Furthermore, the ultra-high concentration UFB generating device 100 is not limited to a piston-type bubble water production device, and the high concentration UFB generating device 200 is not limited to a circulating type UFB generating device, in particular to a multi-stage pressurized dissolution type UFB generating device.

[0082] Although the embodiments of the present invention have been described above with reference to several examples, each embodiment is merely an example, and the scope of the invention as described in the claims can be modified in various ways without departing from the spirit of the invention.
