Description

  The present invention relates to a technique for mixing a plurality of fluids, and more particularly, to a device capable of generating a swirling flow of fluid, miniaturizing by shearing, dissolving at a high concentration, and mixing.

  Conventional methods for mixing fluids, particularly methods for mixing gases in liquids at a high dissolution rate, including mixing using a nozzle, using a hollow fiber filter, installing an impeller in a container, high pressure A method of using a tank, a method of atomizing a liquid, and the like are known.

  In the method using a nozzle, mixing is performed by flowing a high-speed, high-speed gas flow generated by the nozzle into the liquid. Unevenness is likely to occur in mixing, and sufficient mixing alone cannot be achieved.

  In the method using a hollow fiber filter, gas is introduced into a hollow fiber and mixed with a liquid through a minute hole in the hollow fiber, so that a high mixing quality can be maintained. However, filter clogging tends to occur, and parts must be replaced when used for a long time, and frequent maintenance is required.

  The method of providing an impeller in a container requires power such as a motor, and the method of using a high-pressure tank requires a pump that generates high pressure, which increases running costs.

  The method of making the liquid mist is complicated in structure and process, and increases the work cost and the apparatus cost.

  As described above, since there are various problems in each conventional technique, there is a need for a technique that can efficiently mix a plurality of fluids with a simple structure without requiring other power.

  Various techniques have been proposed for this problem. For example, a technique for efficiently dissolving carbon dioxide gas in hot water (see Patent Document 1) has been proposed and is a known technique. More specifically, it is a structure in which a container having a hollow portion is provided, hot water and carbon dioxide gas are swirled in the hollow portion, and fine bubbles are ejected into the bathtub.

  With this technique, hot water and carbon dioxide, which are a plurality of fluids, can be mixed with a simple structure without requiring any other power. However, although carbon dioxide gas and hot water ejected from the hollow part are partially mixed, they are not uniform as a whole because of insufficient mixing immediately after flowing out of the container, and are circulated in the bathtub. Therefore, if there is not enough water level on the bathtub side (a state where the water surface is above the body), it will not be mixed in a high quality and uniform state. Therefore, the problem has not been solved yet.

Hereinafter, an embodiment of a fluid mixing apparatus according to the present invention will be described with reference to the drawings.

  It should be noted that the overall shape of the fluid mixing device and the shape of each part according to the present invention are not limited to the examples shown below, but are within the scope of the technical idea of the present invention, that is, exhibit the same operational effects. It can be changed as appropriate within the range of possible shapes and dimensions.

A first embodiment of the fluid mixing apparatus according to the present invention will be described with reference to FIGS.
1 and 2 show a fluid mixing apparatus 1 according to the present embodiment. FIG. 1 (a) is an overall perspective view, FIG. 1 (b) is a cross-sectional view, FIG. 2 (a) is a plan view, and FIG. 2 (b) is a front view, FIG. 2 (c) is a left side view, and FIG. 2 (d) is a right side view. FIG. 3 is a schematic diagram showing a use process of the fluid mixing device 1 according to the present embodiment, where (a) is a first fluid A inflow process, and (b) is a second fluid B inflow process. , (C) shows the outflow process of the mixed fluid C.

  The fluid mixing device 1 is a device that allows a plurality of fluids to flow in, mixes in the fluid mixing device 1, and flows out the mixed fluid. The fluid mixing apparatus 1 mainly includes a swivel unit 100 and a mixing unit 300, and the swivel unit 100 and the mixing unit 300 are partitioned by a partition plate 200.

  In addition, as a fluid mixed in the fluid mixing apparatus 1, if it is gas, for example, carbon dioxide gas, hydrogen gas, ozone gas, nitrogen gas, air, etc. can be considered, and if it is liquid, for example, water, solvent, fuel, etc. Can be considered.

  The swirl unit 100 is a part that allows the first fluid A and the second fluid B to flow in, swirls in the swirl unit 100, and performs a process prior to mixing. The swivel unit 100 is a substantially rotationally symmetric container having a swivel axis as an axis, and can be a barrel shape or a conical shape. However, considering swirl efficiency, the swivel portion 100 is preferably cylindrical as illustrated. The reason for having a cylindrical shape (substantially rotationally symmetric shape) is to smoothly swirl the fluid within the swivel unit 100. The axis of the cylinder is a line connecting a small hole 210 provided in the partition plate 200 described later and the second fluid inflow port 120, and coincides with a turning axis that is a turning axis of turning. A first fluid inflow port 110 for inflow of the first fluid A is provided in a peripheral portion of the cylinder, and a second fluid for inflow of the second fluid B is provided at one end surface of the cylinder. An inflow port 120 is provided.

  The turning unit 100 and the mixing unit 300 are partitioned by a partition plate 200, and a small hole 210 is provided at the center of the partition plate 200. The first fluid inlet 110 is a peripheral portion of the swivel unit 100 and is installed so that the axial direction of the pipe is deviated from the cylindrical axis so as to guide the flow of the first fluid A in the tangential direction of the periphery. (FIGS. 2C and 2D). By setting it as this form, the 1st fluid A swirls within the swivel unit 100. Then, the pressure near the axis of the cylinder in the swivel unit 100 decreases, and the second fluid B can be smoothly sent near the axis of the cylinder.

  Moreover, the axial direction of the pipe | tube of the 1st fluid inflow port 110 is substantially perpendicular | vertical with respect to the axial direction of a cylinder (FIG.2 (b)). This is in order to match the swirl direction of the fluid in the swivel unit 100. Further, the position of the first fluid inflow port 110 in the swivel unit 100 is installed at a position close to the partition plate 200. This is to increase the turning speed in the vicinity of the small hole 210. The axis of the tube of the second fluid inlet 120 coincides with the axis of the cylinder and the swivel axis, and the tube shape of the second fluid inlet 120 is a shape in which the tip portion protrudes to the inside of the swivel unit 100. (FIG. 1B). This is because the second fluid B is more efficiently fed to the vicinity of the turning axis in the turning operation.

The partition plate 200 is a partition plate that partitions the swivel unit 100 and the mixing unit 300, and has a small hole 210 at the center, and the center of the small hole 210 is on the swivel axis of the swivel unit 100. The small hole 210 is a hole through which the first fluid A and the second fluid B swirling in the swivel unit 100 are fed into the mixing unit 300 at a stretch. The effect of the small hole 210 is that when the fluid of the swirl unit 100 passes through the small hole, the swirl speed is maximized and sent to the mixing unit 300 to promote mixing of the first fluid A and the second fluid B. belongs to. Therefore, if the effect is exhibited, the diameter of the small hole 210 is not particularly limited, and the shape is not particularly limited to a simple round hole, a conical shape, a tapered shape, or the like.
The small holes 210 are also called “orifices”.

  The mixing unit 300 is for sufficiently mixing the first fluid A and the second fluid B. The mixing unit 300 has a cylindrical shape (substantially rotationally symmetric shape) like the swivel unit 100 in order to smoothly swirl the fluid. An outlet 310 for allowing the mixed fluid C to flow out is disposed on one end surface of the cylinder of the mixing unit 300 or on a peripheral side surface in the vicinity of the end surface. A partition plate 200 is disposed on the other end surface of the cylinder of the mixing unit 300 and is partitioned from the swivel unit 100.

  The outflow port 310 is arranged at a different position with respect to the axis of the cylinder (FIG. 2C). The first fluid A and the second fluid B enter the mixing unit 300 through the small holes 210 of the partition plate 200 while mixing, but are not sufficiently mixed when the outflow port 310 is arranged on the axis of the cylinder. May flow out of the outlet 310 as it is. By shifting the outflow port 310 from the axis of the cylinder, the fluid that is sufficiently mixed while swirling in the mixing unit 300 can flow out from the outflow port 310.

  Although not shown in the drawings, a mode in which a partition plate 200 is additionally arranged in the mixing unit 300 and the mixing unit 300 is divided into a plurality of parts is also possible. Such an embodiment is possible because it has a low internal resistance and hardly causes pressure loss. By adopting such a mode, even if the fluids are not sufficiently mixed in the preceding mixing unit 300, the mixing is performed again in the subsequent mixing unit 300. It becomes possible to leak.

  Next, the fluid mixing process will be described with reference to FIG. As shown in FIG. 3A, first, the first fluid A is caused to flow into the swivel unit 100 from the first fluid inlet 110. Since the first fluid inflow port 110 is arranged so that the first fluid A flows in the tangential direction of the circumference of the swivel unit 100, the first fluid A is shown in the swirl unit 100 as indicated by an arrow. A swirling flow is generated. The inside of the mixing unit 300 is filled with the first fluid A that flows in through the small hole 210.

Next, as shown in FIG. 3B, the second fluid B is introduced from the second fluid inlet 120. The inside of the swirling unit 100 is filled with the first fluid A, and a swirling flow is generated by the first fluid A. Therefore, a low pressure portion is formed in the vicinity of the turning axis. Since the low pressure portion is generated along the axis of the swirling flow, it has a long and narrow spiral shape, which is a so-called tornado (second fluid passage T). The second fluid B flowing from the second fluid inlet 120 enters the swivel unit 100 along the tornado. Therefore, the second fluid B can flow widely in the vicinity of the swirling flow axis. In addition, since the pipe portion of the second fluid B is inside the swivel unit 100, the second fluid B can smoothly flow into the passage T of the second fluid.
If the swirl flow is not generated, the second fluid B cannot smoothly enter the swirl unit 100 and stays in the vicinity of the second fluid inlet 120.

  Next, as shown in FIG. 3C, fluid mixing is performed in the mixing unit 300. The first fluid A generating a swirl flow in the swirl unit 100 and the second fluid B distributed in the low pressure portion near the swirl flow axis (second fluid passage T) are formed in the small holes 210. Enters the mixing unit 300 via Since the small hole 210 has a small diameter and is narrow, the first fluid A and the second fluid B pass through the small hole 210 while increasing the turning speed. Therefore, when the second fluid B enters the mixing unit 300, the second fluid is sheared and subdivided. Thereby, the subdivided second fluid B can be easily dissolved in the first fluid A. If the 2nd fluid B is gas, it will become a microbubble of 1 mm or less, and can dissolve gas in water etc. Note that, in the mixing unit 300, the swirl flow remaining in the swirl unit 100 is received and a swirl flow is generated as in the swirl unit 100. This is effective for further mixing of the first fluid A and the second fluid B.

  Since the position of the outlet 310 from which the mixed fluid C flows out is out of the axial direction of the swirling flow, the mixed fluid C is further mixed while swirling in the mixing unit 300. Thereafter, it flows out from the outlet 310.

  As described above, according to the fluid mixing apparatus 1 according to the present embodiment, it is possible to cope with from low pressure to high pressure, it is possible to easily flow in gas, and it has a structure that does not easily clog, and a plurality of fluids can be efficiently supplied. It is a device that can be mixed. Therefore, when mixing multiple fluids, no other power is required, it is possible to work efficiently with a simple structure, and the excellent effect of reducing work cost and equipment cost is demonstrated. To do.

  In addition, since the internal resistance is structurally small, pressure loss is unlikely to occur, so there is no need to increase the pressure of the fluid to be introduced unnecessarily, and the equipment cost can be reduced.

  Furthermore, by making the axis of the pipe of the first fluid inlet 110 and the axis of the pipe of the outlet 310 orthogonal, the pulsation can be suppressed and the retention in the mixing unit 300 can be lengthened.

  Furthermore, if carbon dioxide gas is used as the second fluid B, it is possible to easily dissolve with high efficiency. If water is used as the first fluid A, a carbonated spring is generated if the water is high-concentration carbonated water or hot water. It is possible. If highly pure water and hydrogen gas are used, hydrogen water in which hydrogen is dissolved can be easily generated. Also, if ozone, chlorine, hypochlorous acid is used, sterilizing water having such sterilizing action, and air, microbubble water can be generated by swirling shear, so rivers, lakes, etc. It can also be applied as a water quality improvement device. Furthermore, if fuel is used for the liquid, development such as mixing with air or water to emulsify can be expected. In this way, it is possible to generate a liquid in which a gas is dissolved and the properties of the gas are added.

  Furthermore, if the container is made of metal or the like to have pressure resistance and durability and the liquid is allowed to flow in with a high-power pump, the contact between the gas and liquid can be enhanced, and more efficient dissolution and mixing can be expected. And, for example, if you put hot water in a bathtub and circulate while flowing carbon dioxide using a low-pressure pump, the concentration can be gradually increased, and finally the high concentration up to the vicinity of the solubility limit It is possible to produce carbonated springs.

A second embodiment of the fluid mixing apparatus according to the present invention will be described with reference to FIG. Parts similar to those of the first embodiment are omitted.
FIG. 4 shows the fluid mixing apparatus 1 according to the present embodiment, where (a) is an overall perspective view and (b) is a cross-sectional view.

In the first embodiment, the example in which the first fluid inflow port 110 is provided at a position that is substantially perpendicular to the turning axis and does not intersect the turning axis is described.
In the present embodiment, the first fluid inlet 110 is provided substantially outside the swivel axis and outside the second fluid inlet 120 (peripheral position).

  By making the first fluid inlet 110 substantially horizontal rather than substantially perpendicular to the swivel axis, a swirl flow due to the first fluid A does not occur in the swirl unit 100 as it is. Therefore, a spiral turning path 130 is provided in the turning unit 100. The swirl path 130 is provided in a spiral shape so as to go around the protruding second fluid inlet 120.

  By adopting such a mode, the first fluid A that has flowed in from the first fluid inlet 110 is forcibly swirled by passing through the spiral swirl path 130, and in that state, the swirl unit 100 has the swirl. By being released, a swirl flow in the swirl unit 100 is generated.

A third embodiment of the fluid mixing apparatus according to the present invention will be described with reference to FIG. Parts similar to those of the first embodiment are omitted.
5A and 5B are a schematic view and a cross-sectional view showing the shape of the second fluid inlet of the fluid mixing device 1 according to the present embodiment, and FIG. 5A is a schematic view of the shape of the second fluid inlet 120 in the first embodiment. Sectional views and (b) and (c) are a schematic view and a sectional view of the conical and cylindrical second fluid inlet 120, respectively.

  In the first embodiment, as shown in FIG. 5A, the flow of the swirl flow of the first fluid A is inhibited by the structure in which the pipe portion of the second fluid inlet 120 protrudes into the swirl unit 100. The second fluid B can be introduced from the second fluid inlet 120. However, the pressure in the vicinity of the outlet of the second fluid inlet 120 is affected by the fluctuation of the pressure in the vicinity of the pipe portion of the second fluid inlet 120 protruding into the swirl unit 100. For this reason, the inflow amount of the second fluid B may become unstable due to pressure fluctuation.

  Therefore, in order to reduce the influence of the pressure in the vicinity of the pipe portion of the second fluid inflow port 120 protruding into the swirl unit 100, the shape of the second fluid inflow port 120 is conical as shown in FIG. It can be considered to be a mold or a cylindrical shape as shown in FIG. With such a structure, fluctuations in internal pressure are not concentrated at the outlet of the second fluid inlet 120. Therefore, the influence of the internal pressure of the swivel unit 100 when the second fluid B is introduced can be suppressed, and the inflow of the second fluid B can be made smoother.

  Thus, mixing can be performed with higher efficiency by changing the shape of the second fluid inlet 120.

A fourth embodiment of the fluid mixing apparatus according to the present invention will be described with reference to FIG. Parts similar to those of the first embodiment are omitted.
6A and 6B are a schematic view and a cross-sectional view showing the shape of the small hole 210 of the fluid mixing apparatus 1 according to the present embodiment, where FIG. 6A is a tapered shape of the small hole 210 and FIG. (C) shows a small hole 210 having a Venturi tube shape.
In the first embodiment, the small hole 210 has been described as an example of a simple hole, but the effect of mixing can be enhanced by changing the shape.

  The first fluid A, the second fluid moving from the swivel unit 100 to the mixing unit 300 by making the shape wide at the inflow side of the small hole 210 as shown in FIGS. 6A and 6B and narrow at the outflow side. With the taper structure, the fluid B has a narrow turning speed with a narrow hole 210, and then the shearing and fragmentation can be more effectively advanced.

  As shown in FIG. 6C, in the case of a venturi tube shape, the shape is wide on the inflow side of the small hole 210, narrow at the center, and wide at the outflow side, so that the flow into the small hole 210 is smooth, and The flow rate is increased at the center, and shearing and subdivision can be more effectively advanced on the outflow side.

  Thus, mixing can be performed more efficiently by changing the shape of the small holes 210.

A fifth embodiment of the fluid mixing apparatus according to the present invention will be described with reference to FIG. Parts similar to those of the first embodiment are omitted.
FIG. 7 is an overall perspective view of a fourth embodiment of the fluid mixing apparatus 1 according to this embodiment, where (a) shows an example in which the fluid mixing apparatuses 1 are connected in series, and (b) shows the fluid mixing apparatus. 1 shows an example in which a plurality of second fluids B are connected in series, (c) shows an example in which fluid mixing devices 1 are connected in parallel, and (d) shows a fluid mixing device 1 in parallel. In this example, a plurality of second fluids B are connected.
In the first embodiment, the example in which the fluid mixing device 1 is used alone has been described. However, by using a plurality of the fluid mixing devices 1, fluid can be mixed more effectively.

  An example in which the fluid mixing device 1 is connected in series is shown in FIG. The outlet 310 of the fluid mixing device 1a is connected to the first fluid inlet 110 of the fluid mixing device 1b via the connecting pipe 400a. Further, the outlet 310 of the fluid mixing device 1b is connected to the first fluid inlet 110 of the fluid mixing device 1c via the connection pipe 400b. The fluid mixing device 1b and the second fluid inlet 120 of the fluid mixing device 1c are kept closed.

The first fluid A flows into the first fluid inlet 110 of the fluid mixing device 1a, and the second fluid B flows into the second fluid inlet 120. Due to the effect of the fluid mixing device 1, the mixed fluid C flows out from the outlet 310 of the fluid mixing device 1a. By mixing the mixed fluid C into the first fluid inlet 110 of the fluid mixing device 1b through the connection pipe 400a, further mixing is performed in the fluid mixing device 1b, and the first fluid A and the second fluid are mixed. The mixing ratio of B increases. Furthermore, the mixing ratio of the first fluid A and the second fluid B can be further increased by performing an equivalent operation for the fluid mixing device 1c.
Since the structure of the fluid mixing device 1 according to the present invention has a small pressure loss, such a serial configuration can be easily performed.

  Thus, by using the fluid mixing apparatus 1 connected in series, the mixing rate can be further increased even for fluids that are difficult to mix. In addition, the mixing ratio can be increased to the limit.

  As shown in FIG. 7B, by connecting the fluid mixing apparatus 1 in series, other effects can be enhanced. The configuration and connection method of the fluid mixing device 1 in FIG. 7B are the same as those in FIG. The difference is that the second fluid B2 and the second fluid B3 flow in from the second fluid inlet 120 of the fluid mixing device 1b and the fluid mixing device 1c.

In the fluid mixing device 1a, the first fluid A and the second fluid B1 are mixed, and in the fluid mixing device 1b, the second fluid B2 is further mixed. In the fluid mixing device 1c, the second fluid B3 is further mixed. Mix. By using this configuration, a plurality of fluids can be mixed with the first fluid A.
Since the structure of the fluid mixing apparatus 1 according to the present invention has a small pressure loss, such a series configuration can be easily performed.

  As shown in FIG. 7C, other effects can be enhanced by connecting the fluid mixing devices 1 in parallel. With respect to the fluid mixing device 1a, the fluid mixing device 1b, and the fluid mixing device 1c, the first fluid A flows into the first fluid inlet 110 via the connection pipe 420. The second fluid B flows into each second fluid inlet 120 via the connection pipe 430. The respective outlets 310 merge through the connection pipe 410. By using this configuration, a large amount of mixing can be performed.

  As shown in FIG. 7D, other effects can be enhanced by connecting the fluid mixing devices 1 in parallel. With respect to the fluid mixing device 1a and the fluid mixing device 1b, the first fluid A flows into the first fluid inlet 110 via the connection pipe 420. The respective outlets 310 merge through the connection pipe 410. This configuration is the same as in FIG. The second fluid B1 is allowed to flow into the second fluid inlet 120 of the fluid mixing device 1a, and the second fluid B2 is allowed to flow into the fluid mixing device 1b. By using this configuration, a plurality of fluids can be mixed with the first fluid A.

A sixth embodiment of the fluid mixing apparatus according to the present invention will be described with reference to FIG. Parts similar to those of the first embodiment are omitted.
FIG. 8 is an explanatory view showing a usage example of the fluid mixing apparatus 1 according to the present invention.
In the first embodiment, the method of mixing a plurality of fluids has been described. As one of the effective usage methods, an example of a carbonated spring manufacturing apparatus will be described.

The carbonated spring manufacturing apparatus 500 is an apparatus that is attached to the bathtub 600, increases the carbonate concentration of hot water in the bathtub 600, and uses hot water as the carbonated spring.
The carbonated spring manufacturing apparatus 500 includes a fluid mixing apparatus 1, a circulation pump 530, a valve 510, a check valve 520, a cylinder 540, and a circulation port 610 in the bathtub 600. Hot water in the bathtub 600 is taken in from the circulation port 610, pressurized by the circulation pump 530, and flows into the swivel unit 100 of the fluid mixing device 1 from the first fluid inlet 110 of the fluid mixing device 1. Carbon dioxide gas to be mixed flows from the cylinder 540 through the valve 510 and the check valve 520 into the second fluid inlet 120 of the fluid mixing apparatus 1. In the fluid mixing apparatus 1, hot water and carbon dioxide are mixed, and the mixed carbonated spring flows out from the outlet 310 of the fluid mixing apparatus 1 as the mixed fluid C. The carbonated spring that is the mixed fluid C flows out from the circulation port 610 into the bathtub 600.

As described above, by circulating in this manner, the concentration of carbonic acid can be gradually increased, and finally a carbonated spring having a high concentration can be generated up to the limit of solubility.
With this structure, the hot water in the bathtub 600 can be efficiently changed to a carbonated spring without using other power.

  The fluid mixing device according to the present invention has a simple structure, does not require any other power when mixing a plurality of fluids, and can be efficiently mixed without pressure loss. It can be used in any scene where a plurality of fluids are mixed, such as mixing. Therefore, it is considered that the industrial applicability of the present invention is great.

The swirl unit 100 is a part that allows the first fluid A and the second fluid B to flow in, swirls in the swirl unit 100, and performs a process prior to mixing. The swivel unit 100 is a substantially rotationally symmetric container having a swivel axis as an axis, and can be a barrel shape or a conical shape. However, considering swirl efficiency, the swivel portion 100 is preferably cylindrical as illustrated. The reason for having a cylindrical shape (substantially rotationally symmetric shape) is to smoothly swirl the fluid within the swivel unit 100. The axis of the cylinder is a line connecting a small hole 210 provided in the partition plate 200 described later and the second fluid inflow port 120, and coincides with a turning axis that is a turning axis of turning. On the peripheral portion of the cylinder, a first fluid inlet 110 is provided one for flowing the first fluid A, the one end face of the cylinder, for flowing a second fluid B first second fluid inlet 120 is provided one.

The mixing unit 300 is for sufficiently mixing the first fluid A and the second fluid B. The mixing unit 300 has a cylindrical shape (substantially rotationally symmetric shape) like the swivel unit 100 in order to smoothly swirl the fluid. One outlet 310 for allowing the mixed fluid C to flow out is disposed on one end surface of the cylinder of the mixing unit 300 or on the peripheral side surface in the vicinity of the end surface. A partition plate 200 is disposed on the other end surface of the cylinder of the mixing unit 300 and is partitioned from the swivel unit 100.

Still further, in the fluid mixing device according to the present invention, the first fluid inflow port is substantially perpendicular to the swivel axis, and the inflow direction does not intersect the swirl axis and is more than the second fluid inflow port. It is the structure provided in the position near a partition plate .

In addition, the fluid mixing device according to the present invention may employ a configuration in which the outlet is a surface facing the second fluid inlet and is provided at a position different from the turning axis.

Moreover, the axial direction of the pipe | tube of the 1st fluid inflow port 110 is substantially perpendicular | vertical with respect to the axial direction of a cylinder (FIG.2 (b)). This is in order to match the swirl direction of the fluid in the swivel unit 100. Further, the position of the first fluid inlet 110 in the swivel unit 100 is installed at a position closer to the partition plate 200 than the second fluid inlet 120 . This is to increase the turning speed in the vicinity of the small hole 210. The axis of the tube of the second fluid inlet 120 coincides with the axis of the cylinder and the swivel axis, and the tube shape of the second fluid inlet 120 is a shape in which the tip portion protrudes to the inside of the swivel unit 100. (FIG. 1B). This is because the second fluid B is more efficiently fed to the vicinity of the turning axis in the turning operation.

The mixing unit 300 is for sufficiently mixing the first fluid A and the second fluid B. The mixing unit 300 has a cylindrical shape (substantially rotationally symmetric shape) like the swivel unit 100 in order to smoothly swirl the fluid. One outlet 310 for allowing the mixed fluid C to flow out is disposed on one end face of the cylinder of the mixing unit 300 . A partition plate 200 is disposed on the other end surface of the cylinder of the mixing unit 300 and is partitioned from the swivel unit 100.
