[Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2007-098310 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the two-fluid nozzle described in Patent Document 1, the mixing efficiency is increased by colliding the gas and liquid with the inner wall of the mixing space, so the fluid injected into the mixing space needs to have a flow velocity that allows it to collide with the inner wall of the mixing space.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. Note that the following embodiments do not limit the inventions according to the claims, and not all of the combinations of features described in the embodiments are necessarily essential to the solution of the invention. In addition, in the present embodiments, the scale and dimensions of each component may be exaggerated, and some components may be omitted.

[0014] [Overall configuration of the fluid mixing device] First, a fluid mixing apparatus 100 according to this embodiment will be outlined with reference to Fig. 1. The fluid mixing apparatus 100 according to this embodiment generally includes a first fluid supply mechanism 110 capable of supplying a first fluid FF, a second fluid supply mechanism 120 capable of supplying a second fluid SF, and a fluid mixing member 1 for mixing the first fluid FF and the second fluid SF. Note that in this specification, the term "fluid" will be explained as including liquid and gas, and also as including a liquid or gas containing powder or the like.

[0015] The fluid mixing apparatus 100 according to the present embodiment is configured to be used mainly for mixing gas and liquid. However, the use is not limited to this, and the fluid mixing apparatus 100 may be used for any use in which two or more fluids are mixed. For example, the fluid mixing apparatus 100 may be used for mixing gas and gas, for mixing liquid and liquid, or for mixing gas and liquid containing powder.

[0016] 1, the first fluid supply mechanism 110 includes a first fluid supply pump 112. The first fluid supply pump 112 is configured to be connectable to a first flow path 20 of the fluid mixing member 1, which will be described later, via a connecting member (not shown) such as a tube. The first fluid supply pump 112 may have any configuration capable of supplying at least the first fluid FF to the fluid mixing member 1, and various known configurations may be adopted. For example, when the first fluid FF is a gas, an air pump may be adopted as the first fluid supply pump 112, and when the first fluid FF is a liquid, a liquid pump may be adopted.

[0017] 1, the second fluid supply mechanism 120 includes a second fluid supply pump 122. The second fluid supply pump 122 is configured to be connectable to a second flow path 30 of the fluid mixing member 1, which will be described later, via a connecting member (not shown) such as a tube. The second fluid supply pump 122 may have any configuration capable of supplying at least the second fluid SF to the fluid mixing member 1, and various known configurations may be adopted. For example, when the second fluid SF is a gas, an air pump may be adopted as the second fluid supply pump 122, and when the second fluid SF is a liquid, a liquid pump may be adopted.

[0018] In this embodiment, the first fluid supply mechanism 110 and the second fluid supply mechanism 120 are configured to be detachable from the fluid mixing member 1 via connecting members, but this is not limited to this. For example, the first fluid supply mechanism 110 and the second fluid supply mechanism 120 may be formed integrally with the fluid mixing member 1, thereby making them non-detachable.

[0019] Furthermore, in this embodiment, the first fluid supply mechanism 110 is configured so that the supply amount of the first fluid FF to the fluid mixing member 1 is greater than the supply amount of the second fluid SF supplied from the second fluid supply mechanism 120 described below.

[0020] In this embodiment, the first fluid supply pump 112 is a medium pressure pump (not shown) and the second fluid supply pump 122 is a low pressure pump (not shown), thereby creating a difference in the supply amounts of the first fluid FF and the second fluid SF. However, the configuration for creating a difference in the supply amounts of the first fluid FF and the second fluid SF is not limited to the configuration of this embodiment.

[0021] [Overall configuration of fluid mixing components] As shown in Figures 1 to 5, the fluid mixing member 1 according to this embodiment generally comprises a mixing section 10 having a mixing chamber 15 capable of mixing a first fluid FF and a second fluid SF to generate a mixed flow MF, a first flow path 20 for introducing the first fluid FF into the mixing chamber 15, a second flow path 30 for introducing the second fluid SF into the mixing chamber 15, and a discharge port 40 capable of discharging the mixed flow MF.

[0022] In this specification, in a state where the first flow path 20 is connected to the first fluid supply mechanism 110 and the second flow path 30 is connected to the second fluid supply mechanism 120 (state in FIG. 1), the direction in which the first flow path 20 is located (upward direction in FIG. 1) is described as "upward", and the direction in which the discharge port 40 is located (downward direction in FIG. 1) is described as "downward". In addition, in this specification, the direction from the first flow path 20 and the second flow path 30 toward the discharge port 40 is described as "downstream", and the opposite direction is described as "upstream". Furthermore, in this specification, a cross section along the vertical direction of the fluid mixing member 1 (cross section along line AA' in FIG. 2) is referred to as a "vertical cross section" (see FIG. 3), and a cross section perpendicular to the vertical direction of the fluid mixing member 1 (cross section along line BB' in FIG. 3) is referred to as a "horizontal cross section" (see FIG. 4). However, the vertical direction in this specification is not necessarily the vertical direction in an actual use state.

[0023] In this embodiment, the first fluid FF supplied to the fluid mixing member 1 is a gas, and the second fluid SF is a liquid, but is not limited thereto. The fluid mixing member 1 according to this embodiment can be used in any combination, such as a combination in which the first fluid FF is a liquid and the second fluid SF is a gas, a combination in which the first fluid FF is a liquid and the second fluid SF is also a liquid, or a combination in which the first fluid FF is a gas containing powder and the second fluid SF is a liquid. Examples of gas include air, ozone, oxygen, and carbon dioxide, and examples of liquid include water, sewage (wastewater), alcohol, oil, acid, sugar solution, and chemicals such as sodium hypochlorite solution, but are not limited thereto.

[0024] The material of the fluid mixing member 1 is not particularly limited, and various known materials can be adopted depending on the application, the type of liquid and gas to be mixed, etc. Furthermore, the fluid mixing member 1 is preferably formed by integral molding using the above-mentioned materials, etc., but is not limited thereto, and may have a structure in which the mixing section 10, the first flow path 20, the second flow path 30, and the discharge port 40, which are molded as separate members, are assembled into an integral unit.

[0025] [Mixing section configuration] As shown in FIGS. 3 to 5, the mixing section 10 includes an outer wall 12, a mixing chamber 15 formed inside the outer wall 12, and a central pillar section 16 provided inside the mixing chamber 15.

[0026] As shown in Fig. 1, the outer wall 12 has a cylindrical peripheral wall and an upper wall covering the upper end of the peripheral wall, and is generally formed in a substantially cylindrical shape with a recess near the center. However, this is not limited thereto, and for example, the mixer 10 may be generally formed in a rectangular or prismatic shape, or in other shapes. A first flow path 20 and a second flow path 30 are provided on the upper wall of the outer wall 12, and a discharge port 40 is provided on the lower end of the outer wall 12.

[0027] As shown in Figures 3 to 5, the mixing chamber 15 is an internal space defined by the outer wall 12 and the central pillar portion 16. In this embodiment, as shown in Figure 4, the mixing chamber 15 has a circular horizontal cross section and forms a space that is continuous in the circumferential direction as a whole.

[0028] The mixing chamber 15 is formed so that the projected area in a predetermined horizontal cross section is larger than the opening projected area of ​​the introduction hole 26 of the first flow path 20 in the horizontal cross section. The mixing chamber 15 is configured so that the projected area in a predetermined horizontal cross section is more than twice the opening projected area of ​​the introduction hole 26 of the first flow path 20 described later in the horizontal cross section. Specifically, the projected area of ​​the mixing chamber 15 in a cross section (horizontal cross section) perpendicular to the extending direction of the wall surface 16b described later is preferably from two to ten times, more preferably from five to ten times, the projected area of ​​the introduction hole 26 in the same cross section (horizontal cross section). Here, when the projected area of ​​the mixing chamber 15 differs depending on the position of the horizontal cross section, the projected area of ​​the mixing chamber 15 can be the projected area in the horizontal cross section (cross section along the line BB' in FIG. 3) at the lower end of the introduction hole 26 described later.

[0029] 3 and 5, the central pillar 16 is formed in a generally conical shape extending downward from the upper end of the mixing chamber 15. Specifically, the central pillar 16 includes a tapered portion 16a having a generally conical cylindrical shape that tapers from the upper wall of the outer wall 12 toward the discharge port 40, and a generally cylindrical wall surface 16b that extends further toward the discharge port 40 from the lower end of the tapered portion 16a.

[0030] 3 and 5, the tapered portion 16a has a hollow interior, and the hollow constitutes an introduction portion 24 (described later) of the first flow path 20. Also, an introduction hole 26 (described later) of the first flow path 20 is formed in the tapered portion 16a.

[0031] The wall surface 16b is formed in a substantially cylindrical shape extending in a substantially straight line from the introduction hole 26 formed in the tapered portion 16a toward the discharge port 40. Specifically, the wall surface 16b is configured to extend along the same direction as the axial direction of the first flow path 20. More specifically, as shown in FIG. 3 and FIG. 5, the wall surface 16b is provided at a position coaxial with the first flow path 20 formed on the central axis of the mixing portion 10, and the extending direction of the wall surface 16b is configured to be the same direction as the extending direction of the first flow path 20. The lower end of the wall surface 16b is separated from the discharge port 40 and is formed in a conical shape that tapers toward the discharge port 40. Note that the wall surface 16b is preferably formed to extend from the introduction hole 26 to the vicinity of the upper end of the discharge port 40, but is not limited thereto, and may be formed to extend from the introduction hole 26 to the vicinity of the center of the mixing chamber 15.

[0032] As shown in FIG. 3, the wall surface 16b is located entirely within the mixing chamber 15 and is configured to cause a mixed flow MF consisting of a first fluid FF introduced into the mixing chamber 15 from an inlet hole 26 of the first flow path 20 and a second fluid SF introduced into the mixing chamber 15 from an inlet hole 34 of the second flow path 30 (described later) to flow along the wall surface 16b.

[0033] [Configuration of the first flow path] As shown in Figs. 1 to 4, the first flow path 20 is configured to be able to introduce the first fluid FF into the mixing chamber 15. Specifically, as shown in Figs. 1 and 3, the first flow path 20 includes a cylindrical portion 22 connectable to the first fluid supply mechanism 110 via a connecting member, an introduction portion 24 formed in the internal space of the central column portion 16, and an introduction hole 26 penetrating the tapered portion 16a of the central column portion 16 and facing the mixing chamber 15. The internal space of the cylindrical portion 22 and the introduction portion 24 are in communication with the mixing chamber 15 via the introduction hole 26, and the first fluid FF supplied from the first fluid supply mechanism 110 via the connecting member is caused to flow through the cylindrical portion 22, the introduction portion 24, and the introduction hole 26 in this order, and is introduced into the mixing chamber 15.

[0034] The cylindrical portion 22 extends upward from the upper wall of the outer wall 12 of the mixing section 10, and has at its upper end a connecting portion 22a to which a connecting member can be connected. The cylindrical portion 22 is preferably formed at a position where its central axis is coaxial with the central axis of the mixing section 10, but is not limited thereto.

[0035] The introduction part 24 is formed in the internal space of the tapered part 16a of the central column part 16, as shown in Fig. 3. The introduction part 24 is continuous with the internal space of the cylindrical part 22, and is formed in a conical shape as a whole. Specifically, as shown in Fig. 3, the introduction part 24 has a diameter larger than the inner diameter of the cylindrical part 22 at its upper part, and a diameter smaller than the inner diameter of the cylindrical part 22 at its lower part. However, this is not limited to this, and the introduction part 24 may have the same inner diameter as the cylindrical part 22. In addition, the shape of the introduction part 24 is not limited to this, and various shapes can be adopted.

[0036] The introduction hole 26 is provided penetrating the tapered portion 16a of the central pillar portion 16, and is configured to be able to introduce the first fluid FF supplied to the introduction portion 24 into the mixing chamber 15. The introduction hole 26 is formed along the axial direction of the first flow path 20 in the tapered portion 16a which is inclined with respect to the axial direction of the first flow path 20. By being configured in this manner, the introduction hole 26 is recognized as a substantially elliptical shape as a whole in the vertical cross-sectional view shown in FIG. 3, and recognized as a substantially perfect circle as a whole in the horizontal cross-sectional view shown in FIG.

[0037] The inlet hole 26 of the first flow path 20 is preferably formed downstream of the inlet hole 34 of the second flow path 30 described below. Specifically, as shown in Fig. 3, the inlet hole 26 of the first flow path 20 is provided below the inlet hole 34 of the second flow path 30, and is configured to introduce the first fluid FF downstream of the second fluid SF introduced into the mixing chamber 15 via the inlet hole 34.

[0038] 3 and 4, a plurality of introduction holes 26 are provided in the circumferential direction of the introduction portion 24. Specifically, the introduction holes 26 are provided at equal intervals in the circumferential direction of the introduction portion 24. Note that the introduction holes 26 are not limited to being provided at equal intervals along the circumferential direction of the introduction portion 24, and may be, for example, a configuration in which only one introduction hole is formed.

[0039] [Configuration of the second flow path] 1 to 4, the second flow path 30 is configured to be able to introduce the second fluid SF into the mixing chamber 15. Specifically, as shown in Figs. 1 and 3, the second flow path 30 includes a cylindrical portion 32 connectable to the second fluid supply mechanism 120 via a connecting member, and an introduction hole 34 facing the mixing chamber 15. The internal space of the cylindrical portion 32 communicates with the mixing chamber 15 via the introduction hole 34, and is configured to cause the second fluid SF supplied from the second fluid supply mechanism 120 via the connecting member to flow through the cylindrical portion 32 and the introduction hole 34 in this order, and to be introduced into the mixing chamber 15.

[0040] The cylindrical portion 32 extends obliquely upward from the upper wall of the outer wall 12 of the mixing section 10, and has a connection portion 32a at its upper end to which a connection member can be connected. The cylindrical portion 32 is formed extending from the upper end of the mixing section 10 in a direction intersecting the axial direction of the mixing section 10, but is not limited thereto. For example, the cylindrical portion 32 may be formed extending in the same direction as the axial direction of the mixing section 10.

[0041] The introduction hole 34 is a through hole penetrating the upper wall of the outer wall 12 of the mixing section 10, and is configured to be able to introduce the second fluid SF supplied to the cylindrical section 32 into the mixing chamber 15. The introduction hole 34 is formed above (upstream of) the introduction hole 26 of the first flow path 20. Note that, in this embodiment, only one introduction hole 34 is formed, but this is not limited thereto, and a plurality of introduction holes may be formed. The introduction hole 34 is formed to have the same diameter as the inner diameter of the cylindrical section 32, but this is not limited thereto, and the inner diameter of the introduction hole 34 may be, for example, smaller or larger than the inner diameter of the cylindrical section 32.

[0042] [Outlet configuration] As shown in Figures 1 to 3, the discharge port 40 is configured to be able to discharge the mixed flow MF generated in the mixing chamber 15. Specifically, as shown in Figure 3, the discharge port 40 is formed in a cylindrical shape having the same axis as the mixing section 10, and is formed to extend downward from the mixing section 10. In addition, the discharge port 40 is provided with a connection part 40a at its lower part, and is configured to be able to be connected to another member such as a storage tank (not shown) or a water tank (not shown).

[0043] In this embodiment, the discharge port 40 is formed in a cylindrical shape having the same axis as the mixing section 10, but is not limited to this. For example, the discharge port 40 may be formed to extend in a direction perpendicular to the axial direction of the mixing section 10, and may not be formed in a cylindrical shape. In this embodiment, the discharge port 40 is configured to have a diameter narrower than the diameter of the mixing section 10, but is not limited to this, and the diameter of the discharge port 40 may be formed to be the same as the inner diameter of the mixing section 10.

[0044] [Operation of the fluid mixing device according to this embodiment] Next, the operation of the fluid mixing apparatus 100 according to this embodiment will be described with reference to Fig. 1. First, as shown in Fig. 1, a first fluid FF is supplied to the fluid mixing member 1 by a first fluid supply pump 112 of a first fluid supply mechanism 110. In parallel with the supply of the first fluid FF by the first fluid supply mechanism 110, a second fluid SF is supplied to the fluid mixing member 1 by a second fluid supply pump 122 of a second fluid supply mechanism 120.

[0045] 1, the first fluid FF supplied to the fluid mixing unit 1 passes through the cylindrical portion 22 of the first flow path 20, is supplied to the introduction portion 24, and is then introduced into the mixing chamber 15 via the introduction hole 26. In parallel with this, the second fluid SF supplied to the fluid mixing unit 1 passes through the cylindrical portion 32 of the second flow path 30, and is introduced into the mixing chamber 15 via the introduction hole 34. At this time, in the fluid mixing device 100 according to this embodiment, the volume of the first fluid FF changes (becomes larger) due to negative pressure when it is introduced into the mixing chamber 15, thereby further increasing the mixing efficiency with the second fluid SF.

[0046] The first fluid FF and the second fluid SF introduced into the mixing chamber 15 are mixed in the mixing chamber 15 to generate a mixed flow MF, and as shown in Fig. 1, the generated mixed flow MF is caused to flow along a wall surface 16b provided in the mixing chamber 15 toward the discharge port 40 and is discharged from the discharge port 40 to the outside of the fluid mixing unit 1. At this time, by causing the mixed flow MF to flow in a laminar state along the wall surface 16b, the two fluids can be effectively mixed.

[0047] [Advantages of the fluid mixing member and fluid mixing device according to this embodiment] As described above, the fluid mixing component 1 according to this embodiment is a fluid mixing component 1 comprising a mixing chamber 15 capable of mixing a first fluid FF and a second fluid SF to generate a mixed flow MF, a first flow path 20 for introducing the first fluid FF into the mixing chamber 15, a second flow path 30 for introducing the second fluid SF into the mixing chamber 15, and a discharge port 40 capable of discharging the mixed flow MF, wherein the first flow path 20 has an inlet hole 26 facing the mixing chamber 15 formed therein, and within the mixing chamber 15 is a wall surface 16b extending from the inlet hole 26 of the first flow path 20 towards the discharge port 40, and the projected area of ​​the mixing chamber 15 in a cross-sectional view perpendicular to the extension direction of the wall surface 16b is at least twice the projected area of ​​the inlet hole 26 of the first flow path 20 in the same cross-sectional view.

[0048] The fluid mixing member 1 having such a configuration has the advantage that, even if the flow rate of either or both of the first fluid FF and the second fluid SF supplied into the mixing chamber 15 is weak, the two fluids can be efficiently mixed by utilizing the change in fluid volume. Furthermore, the wall surface 16b provided in the mixing chamber 15 makes it possible to make the introduced first fluid FF and second fluid SF into laminar flows along the wall surface 16b, so that the first fluid FF and the second fluid SF can be mixed more efficiently.

[0049] Moreover, in the fluid mixing member 1 according to this embodiment, the second flow path 30 is formed with an inlet 34 facing the mixing chamber 15, and the inlet 26 of the first flow path 20 is formed downstream of the inlet 34 of the second flow path 30. According to the fluid mixing member 1 having such a configuration, it is possible to more effectively draw in the second fluid SF, and therefore it is possible to more efficiently generate the mixed flow MF.

[0050] Furthermore, in the fluid mixing member 1 according to this embodiment, the wall surface 16b is configured to extend along the same direction as the axial direction of the first flow path 20. According to the fluid mixing member 1 having such a configuration, it is possible to generate the mixed flow MF more efficiently.

[0051] Moreover, in the fluid mixing member 1 according to this embodiment, the introduction hole 26 of the first flow path 20 is formed along the axial direction of the first flow path 20. According to the fluid mixing member 1 having such a configuration, it is possible to increase the efficiency of the volume change of the first fluid FF, and therefore it is possible to generate the mixed flow MF more efficiently.

[0052] Furthermore, in the fluid mixing apparatus 100 according to this embodiment, the first fluid supply mechanism 110 is configured so that the supply amount of the first fluid FF is greater than the supply amount of the second fluid SF supplied from the second fluid supply mechanism 120. According to the fluid mixing apparatus 100 having such a configuration, by generating a flow rate difference between the first fluid FF and the second fluid SF, even if the flow rate of one fluid is low, it is possible to efficiently generate a mixed flow MF by utilizing the flow rate of the other fluid.
