  The present invention relates to a gas that is mixed with a liquid, another liquid that is mixed with a liquid, and a miniaturization mixing apparatus that makes a solid mixed with a liquid fine and mixes it with the liquid.

  2. Description of the Related Art Conventionally, a mixed fluid obtained by refining a gas or a liquid and dispersing it in another liquid has been utilized in many technical fields because the finely divided particles exhibit physical properties different from those in a bulk state.

  For example, it has been studied to use water in which bubbles having a diameter of about 10 nm to several 100 nm (hereinafter referred to as nanobubbles) are dispersed for purification of sewage, promotion of growth in aquaculture, and promotion of plant cultivation. As a method for producing nanobubbles, a gas-liquid shearing method is known in which shearing force is applied to a mixed fluid formed by mixing air with water to generate nanobubbles by refining the air. The nano-bubble generating device that performs the gas-liquid shearing method includes an upstream screw portion having a spirally formed flow channel in a cylindrical casing, and a downstream cutter portion in which protrusions are disposed on the flow channel wall. (For example, refer to Patent Document 1).

  This nanobubble generating device applies a swirl force and a centrifugal force to the mixed fluid of air and water pumped into the casing, and then divides and refines the bubbles in the mixed fluid at the cutter portion. Produces a gas-liquid mixed fluid containing fine bubbles of about 0.5 to 3 μm.

  However, the nanobubble generating device described in Patent Document 1 has a problem that the generation efficiency of nanobubbles is low when the turning force and centrifugal force are applied by the screw portion and the bubbles are divided by the cutter portion.

  In the nanobubble generating device, a spiral partition wall is disposed in contact with the inner surface of the casing on the screw portion, and a plurality of protrusions are fixed on the inner surface of the casing on the cutter portion.

An example of a mixed fluid in which a liquid is mixed with a liquid is a water-oil emulsion in which oil particles are mixed with water. An example of a mixed fluid in which a solid is mixed with a liquid is organic sludge in which particles of an organic solid are mixed with water.

Preferably, it means reducing the particle size to a range of 10 nm to 50 μm. For example, when the object of miniaturization is gas, miniaturization refers to generating micro-nano bubbles having a diameter of 10 nm to 50 μm. Here, the micro-nano bubble is a general term for micro-bubbles and micro-nano bubbles.

(First embodiment)
FIG. 1 is a longitudinal sectional view schematically showing a miniaturization mixing apparatus according to a first embodiment of the present invention. This refined mixing apparatus 1 is a refined mixing apparatus that refines air as a gas dispersed in water as a liquid to generate micro-nano bubbles.

  The refinement mixing apparatus 1 includes a cylindrical casing 2 and a cylindrical refinement unit 3 accommodated in the casing 2. On one end face and the other end face of the casing 2, there are an inlet pipe 24 formed with an inlet opening 2a into which the mixed fluid flows and an outlet pipe 25 formed with an outlet opening 2b through which the fine mixed fluid is discharged at the tip. Is provided. An outlet pipe 324 extending from the other end surface of the miniaturization unit 3 is fitted inside the outlet pipe 25. Thereby, the miniaturization unit 3 is detachably attached to the casing 2.

  The miniaturization unit 3 includes an inlet block 320 in which an inlet opening 3a is formed at an end face, a rectifying block 321 in which a rectifying body 6 is built, and a vibration block 322 in which an orifice vibrating member 5 as a perforated vibrating body is built. The outlet block 323 having the outlet pipe 324 formed on the end face is sequentially connected. The inlet block 320, the rectifying block 321, the vibration block 322, and the outlet block 323 have spiral grooves formed at the respective edge portions, and the spiral grooves at the respective edge portions can be screwed together to be separated from each other. It is connected to. The inlet block 320, the rectifying block 321, the vibration block 322, and the outlet block 323 may be detachably connected to each other by a rod or the like extending in the axial direction. Inside the inlet block 320, the rectifying block 321, the vibration block 322, and the outlet block 323, a flow path 4 that guides the mixed fluid flowing from the inlet opening 3 a to the outlet pipe 324 is formed.

  As shown in the plan view of FIG. 2, the orifice vibrating member 5 as a perforated vibrating body includes a disk-like plate-like body 50, circular circulation holes 51 formed eccentrically on the plate-like body 50, A plurality of slits 52, 52,... Formed radially from the edge of the flow hole 51 toward the edge of the plate-like body 50. The slits 52, 52,... Extend from positions at substantially equal angular intervals on the edge of the flow hole 51. The slit 52 located in the part where the distance between the edge of the plate-like body 50 and the edge of the circulation hole 51 is short is formed short, and the distance between the edge of the plate-like body 50 and the edge of the circulation hole 51 is long. The slit 52 located at is formed long. In addition, slits 52 at target positions with respect to a line connecting the center of the plate-like body 50 and the center of the flow hole 51 are formed to have the same length. A portion of the plate-like body 50 adjacent to the flow hole 51 and having a substantially trapezoidal shape defined by the edge of the flow hole 51 and the slits 52 and 52 vibrates when the mixed fluid flows through the flow hole 51. It is a vibrating part 53.

  The rectifying body 6 has a spherical shape, and the distance between the surface of the rectifying body 6 and the inner side surface of the rectifying block 321 is substantially uniform in the circumferential direction by four rod-shaped arms 61 extending from the surface in the radial direction of the rectifying block 321. The rectification block 321 is fixed in a state where the rectification block 321 is held.

  A space between the inner side surface of the casing 2 and the outer side surface of the miniaturization unit 3 is formed so as to be filled with the mixed fluid flowing from the inlet opening 2 a of the casing 2.

  A premixing device for mixing air and water is connected to the inlet pipe 24 of the casing 2. As the premixing device, for example, a device that includes a pump that pressurizes water and an ejector nozzle that is disposed on the discharge side of the pump and discharges air, and that mixes air with the pressure water discharged from the pump by the ejector nozzle is used. be able to. In addition, as a premixing apparatus, you may use a well-known gas-liquid mixing pump.

  The said refinement | mixing mixing apparatus 1 operate | moves as follows. First, the premixing device is activated, and a mixed fluid, which is water containing bubbles, is supplied to the inlet opening 2a via a supply pipe (not shown). The bubbles of the mixed fluid supplied from the premixing device preferably have a diameter of about 100 μm to several millimeters. The supplied mixed fluid preferably has a flow rate of about 1 to 50 L / min and a pressure of about 0.1 to 5 MPa at the inlet opening 2 a of the inlet pipe 24. In this mixed fluid, water is mixed at a rate of 0.8 to 40 L / min, and air is mixed at a rate of 0.2 to 10 L / min.

  The mixed fluid that has flowed into the casing 2 from the inlet opening 2a through the inlet pipe 24 fills the space between the inner side surface of the casing 2 and the outer side surface of the miniaturization unit 3, and then from the inlet opening 3a to the miniaturization unit 3. Flows into the interior.

  The mixed fluid that has flowed into the micronization unit 3 is micronized in the process of passing through the flow path 4. That is, first, the mixed fluid is rectified by passing between the inner surface of the rectifying block 321 and the surface of the spherical rectifying body 6. The rectified mixed fluid is guided to the vibration block 322, and the flow velocity increases as it passes through the flow hole 51 of the orifice vibration member 5, and the pressure on the downstream side of the orifice vibration member 5 decreases. Due to the pressure change and the flow force, the vibrating portion 53 of the orifice vibrating member 5 vibrates. Due to the action of pressure and flow when the mixed fluid passes through the circulation hole 51 and the vibrating action of the vibrating portion 53 of the orifice vibrating member 5, the bubbles of the mixed fluid are refined, and the micro-nano bubbles having a diameter of 10 nm to 50 μm. Is generated. The micronized mixed fluid containing the micro / nano bubbles thus generated by the orifice vibrating member 5 is discharged to the outside through the outlet pipe 324 of the micronizing unit 3 and the outlet pipe 25 of the casing 2.

  Since the refined mixing apparatus 1 includes the refined unit 3 having the orifice vibrating member 5 and the rectifying body 6, the refined mixed fluid containing nanobubbles can be efficiently generated. Further, a micronization unit 3 which is a part for miniaturizing bubbles and is an object of cleaning and repair is detachably attached to the casing 2. Therefore, by removing the miniaturization unit 3 from the casing 2, the miniaturization unit 3 can be easily cleaned and repaired.

  Further, the miniaturization unit 3 is formed by connecting an inlet block 320, a rectifying block 321, a vibration block 322, and an outlet block 323 so as to be separable from each other. Therefore, by separating the blocks from each other, the rectifying body 6 of the rectifying block 321 and the orifice vibration member 5 of the vibration block 322 can be easily cleaned and repaired.

  Further, the micronization unit 3 is vibrated by the operation of the orifice vibration member 5, but the mixed fluid before the micronization of the bubbles is performed between the inner surface of the casing 2 and the outer surface of the micronization unit 3. Therefore, vibration transmitted from the miniaturization unit 3 to the casing 2 can be mitigated. In addition, the pressure difference can be increased by reducing the pressure difference between the inside and outside of the miniaturization unit 3. Further, even if the mixed fluid leaks from the inside of the miniaturization unit 3, the mixed fluid can be recovered in the casing 2, so that leakage of the mixed fluid to the outside of the casing 2 can be prevented.

  Further, the miniaturization mixing apparatus 1 of the present embodiment can generate micro-nano bubbles with a relatively simple configuration in which the miniaturization unit 3 having the orifice vibrating member 5 and the rectifying body 6 is provided in the casing 2. . Therefore, the miniaturization mixing apparatus 1 can be easily reduced in size, can be created with a small number of parts, and cost can be easily reduced. In addition, the miniaturized mixing apparatus 1 of the present embodiment has a smaller pressure loss in the mixed fluid than a conventional nanobubble generating apparatus that includes a swirling flow path and a flow path provided with protrusions. Therefore, since it can operate at a lower pressure and lower flow rate than the conventional one, the countermeasure against pressure resistance can be simplified, and the cost can be reduced.

  The refined mixed fluid containing micro-nano bubbles generated by this refined mixing device 1 has specific physicochemical characteristics compared to water containing micron-level bubbles. For example, in water purification and fish farming It can be used to promote growth and plant cultivation. In addition, the refinement | mixing mixing apparatus 1 of this embodiment can mix oxygen and another gas instead of air according to the intended purpose of refinement | mixing fluid.

Is substantially formed by a through-hole 41 formed in parallel. At substantially the center in the axial direction of the through hole 41, the same orifice vibrating member 5 as in the first embodiment is incorporated so as to extend in the transverse direction of the through hole 41. One end face of the block main body 330 is provided with a communication path 331 formed by a groove that connects the edge of the opening of the gas reservoir 7 and the edge of the through hole 41 on the one end face side. The vibration block 303 is formed with two rod holes 332 and 332 through which the rod 306 is inserted, on both sides of a line connecting the gas reservoir 7 and the through hole 41 when viewed from the end face side.

  FIG. 5 is a perspective view showing the end face plate 304 on the inlet side of the miniaturization unit 30. The end face plate 304 on the entrance side has a disk shape, and a plurality of small-diameter through holes 341, 341,. These through holes 341, 341,... Function as inlet openings of the miniaturization unit 30, and the end plate 304 having these through holes 341, 341,. It functions as a filter that prevents inflow. Two rod holes 342 and 342 are formed at line symmetry positions of the end face plate 304.

  The end face plate 301 on the outlet side of the miniaturization unit 30 is provided with an outlet pipe 305 passing through the center, and the outlet pipe 305 is fitted inside the outlet pipe 25 of the casing 20. The miniaturization unit 30 is detachably connected to the casing 20 by the outlet pipe 305. The end face plate 301 on the outlet side is formed with rod holes on both sides of the outlet pipe 305. Rods 306 and 306 are inserted into rod holes of the end face plate 304 on the inlet side, the end block 302, the five vibration blocks 303, 303,..., The end block 302 and the end face plate 301 on the outlet side. Yes. The end plates 301 and 304 on the entrance and exit sides are pressed against each other in the opposite direction by bolts 307 and 307 screwed to both ends of the rods 306 and 306, and the constituent members of the miniaturization unit 30 are connected and fixed together.

  In the miniaturization unit 30, the five vibration blocks 303, 303,... And the end block 302 are connected to each other, so that the through holes 41, 41,. .. and the inside of the end block 302 communicate with each other to form a flow path 4 of the mixed fluid. The opening of the bottomed hole formed in one end face of the vibration block 303 is closed by the adjacent vibration block 303 or the end face plate 304 on the inlet side, and the gas reservoir 7 is provided for each vibration block 303, 303,. 7, ... are formed. These gas reservoirs 7,7, ... are connected to the flow path 4 through the communication paths 331,331, ... formed for each vibration block 303,303, ....

  The orifice vibration members 5, 5,... Provided for each vibration block 303, 303,... Across the flow path 4 are arranged between the adjacent orifice vibration members 5, 5 in the flow hole 51. The positions are arranged so as to be different when viewed in the axial direction. Thereby, the flow of the mixed fluid formed in the flow path 4 is appropriately disturbed, and the refinement of the bubbles contained in the mixed fluid is promoted.

  The space between the inner side surface of the casing 20 and the outer side surface of the miniaturization unit 30 is formed so as to be filled with the mixed fluid flowing from the inlet opening 20 a of the casing 20.

  Similarly to the first embodiment, a premixing device that mixes air and water is connected to the inlet pipe 24 of the casing 20.

  The above-mentioned fine mixing device 11 operates as follows. First, the premixing device is activated, and a mixed fluid, which is water containing bubbles, is supplied to the inlet opening 20a through a supply pipe (not shown). The mixed fluid flowing into the casing 20 from the inlet opening 20 a through the inlet pipe 24 fills the space between the inner surface of the casing 20 and the outer surface of the miniaturization unit 30, and then the through holes 341 and 341 of the end face plate 304. ,... Flow into the micronization unit 30.

  The mixed fluid that has flowed into the micronization unit 30 is micronized in the process of passing through the flow path 4. That is, the mixed fluid flows into the through hole 41 of the vibration block 303 through the end block 302 and passes through the flow hole 51 of the orifice vibration member 5 disposed in the through hole 41. At this time, the vibration portion 53 of the orifice vibration member 5 vibrates due to the pressure change and the flow force generated between the upstream and downstream of the orifice vibration member 5, and this vibration is applied to the mixed fluid. Here, the mixed fluid flows through the flow path 4 in a state where the air separated from the mixed fluid or the air present in the flow path 4 at the beginning of operation is accumulated in the gas reservoir 7 communicating with the flow path 4. Thereby, a buffering action is imparted to the flow of the mixed fluid flowing through the flow path 4 and the fluctuation of the pressure. The action of pressure and flow when the mixed fluid passes through the flow hole 51 of the orifice vibration member 5, the vibration action of the vibration part 53 of the orifice vibration member 5, and the buffer action of the gas reservoir 7 are five vibration blocks. 303, 303,... Are applied to the mixed fluid, and the bubbles contained in the mixed fluid are effectively miniaturized. Bubbles thus refined become micro-nano bubbles having a diameter of 10 nm or more and 50 μm or less, and the refined mixed fluid containing the micro-nano bubbles passes through the outlet pipe 305 of the miniaturization unit 30 and the outlet pipe 25 of the casing 20 to the outside. Discharged. The miniaturized mixing apparatus 10 has the ability to generate water containing air micro-nano bubbles having a diameter of 10 nm to 50 μm at a rate of about 1 to 50 L / min.

  Since the refinement mixing apparatus 10 of the present embodiment includes the refinement unit 30 formed by connecting five vibration blocks 303 having the orifice vibrating member 5 and the gas reservoir 7, the refined mixed fluid including nanobubbles is efficiently used. It can be generated well. In addition, a micronization unit 30 that is a part that performs micronization of bubbles and is an object of cleaning and repair is formed to be detachable from the casing 20. Therefore, by removing the miniaturization unit 30 from the casing 20, the miniaturization unit 30 can be easily cleaned and repaired.

  Further, the miniaturization unit 30 is formed by connecting end face plates 301 and 304, an end block 302 and a vibration block 303 so as to be separable from each other. Therefore, by separating the end face plates 301 and 304 and the blocks 302 and 303, the orifice vibration member 5 and the gas reservoir 7 of the vibration block 303 can be easily cleaned and repaired.

  Furthermore, since the space between the inner side surface of the casing 2 and the outer side surface of the miniaturization unit 30 is filled with the mixed fluid, vibration transmitted from the miniaturization unit 30 to the casing 20 during operation can be reduced. Moreover, the pressure difference between the inside and outside of the miniaturization unit 30 can be reduced by the mixed fluid between the inner side surface of the casing 2 and the outer side surface of the miniaturization unit 30, and pressure resistance can be improved. Even if the mixed fluid leaks from the inside of the miniaturization unit 30, the mixed fluid can be recovered in the casing 2, so that leakage of the mixed fluid to the outside of the casing 2 can be prevented. In particular, even if the mixed fluid leaks from the connecting portions of the end face plates 301 and 304 and the blocks 302 and 303 forming the miniaturization unit 30, the leaked mixed fluid can be effectively recovered, and the mixed fluid to the outside of the casing 2 can be recovered. Can prevent leakage.

The end face partition plate 377 and the end face connecting plate 376 are pressed against each other by bolts 307 and 307 screwed to both ends of the rod 306, and the connecting pipe 378, the buffer block 370, and the vibration diaphragm 375 are connected and fixed to each other. ing. A flow path 4 of the mixed fluid is formed inside the connection pipe 378 fixed to each other and inside the flow pipe portion 371 of the buffer block 370.

  When the fine mixing device 14 of the present embodiment is activated, a mixed fluid in which air bubbles are mixed with water is supplied from the inlet opening 20 a of the casing 20 to the inlet pipe 24. The mixed fluid supplied to the inlet pipe 24 flows into the miniaturization unit 37 through the inner peripheral side through hole 377a of the end face partition plate 377 and passes through the outer peripheral side through hole 377b of the end face partition plate 377. It flows between the outer side surface of 37 and the inner side surface of the trunk portion 21 of the casing 20.

  The mixed fluid that has flowed into the micronization unit 37 is micronized in the process of passing through the flow path 4. That is, first, the mixed fluid that has flowed into the connection pipe 378 from the end face partition plate 377 flows between the edge of the through hole of the vibration diaphragm 375 adjacent to the connection pipe 378 and the outer peripheral surface of the spacer 379. Due to the pressure change and flow force generated between the upstream and downstream of the diaphragm 375, the vibration part 365 of the vibration diaphragm 375 vibrates, and this vibration is applied to the mixed fluid. Bubbles are refined by the action of the pressure and flow of the mixed fluid and the vibration action of the vibration part of the vibration diaphragm 375. The mixed fluid refined by the vibration diaphragm 375 flows into the buffer block 370. Here, the air separated from the mixed fluid and the air present in the flow path 4 at the beginning of operation are accumulated in the buffer pipe portion 372, so that a buffering action is imparted to the flow of the mixed fluid and the pressure fluctuation. The mixed fluid that has flowed into the buffer block 370 is rectified when it flows on the outer peripheral side of the spherical rectifier 373, and thereafter is guided to the downstream diaphragm 375 to be refined. In the buffer block 370, the rectifying effect by the rectifying body 373 and the miniaturization by the vibration diaphragm 375 are promoted by the air buffering action of the buffer pipe portion 372. As the mixed fluid flows through the five buffer blocks 370, the diameter of the bubbles is reduced to 10 nm to several tens of μm to generate micro-nano bubbles. The micronized mixed fluid containing micro / nano bubbles generated in this way flows out from the through holes 376a, 376a,... Of the end face connecting plate 376 on the outlet side to the outlet pipe 25 of the casing 2 and is discharged to the outside. This fine mixing device 14 has the ability to generate water containing micro nano bubbles of air having a diameter of 10 nm to 50 μm at a rate of about 1 to 50 L / min.

  According to the miniaturization mixing apparatus 14 of the present embodiment, the buffer block 370 having the rectifier 373 and the vibration diaphragm 375 are alternately connected to constitute the miniaturization unit 37. Therefore, the buffer block 370 and the vibration diaphragm 375 having the same structure are configured. It is possible to produce micro / nano bubbles relatively inexpensively and effectively using a plurality.

  Further, according to the fine mixing device 14 of the present embodiment, since the fine unit 37 can be separated into the individual buffer blocks 370 and the vibration diaphragm 375, cleaning and repair can be easily performed. In addition, by adjusting the number of buffer blocks 370 and vibration diaphragms 375 constituting the miniaturization unit 37, the performance of the miniaturization mixing device 14 is set according to the type of the mixed fluid and the amount of fluid to be miniaturized. And a highly versatile miniaturization mixing device 14 is obtained.

  Note that, in the refinement mixing device 14 of the present embodiment, a gas reservoir may be formed between the casing 20 and the refinement unit 37.

  The micronization mixing apparatus of the first to sixth embodiments generates micro / nano bubbles by micronizing air as a gas mixed in water as a liquid of a medium as a mixed fluid. You may refine | miniaturize gas with respect to the mixed fluid with which other gas was mixed. Further, any liquid may be refined with respect to a mixed fluid in which another liquid is mixed with the liquid of the medium.

  Examples of the mixed fluid in which another liquid is mixed with the liquid of the medium include a mixed fluid in which oil is mixed with water. The water or oil of the mixed fluid is refined to form an emulsion of water and oil. Can be formed. The water-oil emulsion formed by the fine mixing device of the present invention can be used as a fuel for diesel engines, turbine engines, boilers and the like. Since the miniaturized mixing apparatus of the present invention has no portion driven by power, there are few failures, it is easy to disassemble, and cleaning and repair are easy. Therefore, it is possible to reduce the cost of the fuel supply mechanism such as the engine and the boiler and improve the maintainability.

  Moreover, the mixed fluid containing the micro / nano bubbles generated by the miniaturization mixing apparatus of the present invention can be used for various processing applications depending on the miniaturized gas. For example, a liquid mixture containing fine air can be added to the treatment target to purify water quality in lakes and rivers, sewage treatment, promotion of aquaculture in agriculture, hydroponics in agriculture, and agricultural water. It can be used for purification. Moreover, the liquid mixture containing refined ozone can be used for industrial wastewater treatment, parts cleaning, purification of food waste liquid, and the like.

  Moreover, the refined mixing apparatus of the present invention can also produce a refined mixed fluid by refining a solid with respect to a mixed fluid in which a solid is mixed with a liquid of a medium. As such a mixed fluid, there is organic sludge in which organic solids are mixed with water of a medium. According to the refined mixing apparatus of the present invention, organic solids of organic sludge can be refined and dispersed in water to promote aggregation of organic solids. Other examples of this type of mixed fluid include food wastewater such as boiled food such as udon.
