Description

  The present invention relates to a static fluid mixer used for fluid transport piping in various industries such as chemical factories, semiconductor manufacturing fields, food fields, medical fields, and bio fields, and in particular, concentration distribution and temperature in the fluid flow direction. The present invention relates to a static fluid mixer and a device using the static fluid mixer that can be uniformly mixed and mixed.

  Conventionally, as a method for uniformly mixing the fluid flowing in the pipe after being mounted in the pipe, a method using a twisted blade-shaped static mixer element 151 as shown in FIG. 21 has been generally used (for example, Patent Document 1). reference). Usually, the static mixer element 151 is formed by integrally connecting a plurality of minimum unit members in series so that twist directions are alternately different, with a rectangular plate twisted 180 degrees around its longitudinal axis as a minimum unit member. It has a combined structure. This static mixer element 151 is arranged in the pipe 152, a mail connector 153 is attached to both ends of the pipe 152, a flare 155 is attached, and a fastening nut 154 is fastened to form a static mixer. At this time, the outer diameter of the static mixer element 151 is designed to be substantially equal to the inner diameter of the tube 152 so that the fluid is effectively stirred.

  However, since the fluid mixing method using the conventional static mixer is configured to stir the flowing fluid along the flow, the concentration distribution in the radial direction of the pipe is uniform as shown in FIG. Although it can be made uniform, the concentration distribution in the axial direction (flow direction) cannot be made uniform as shown in FIG. 22B. For this reason, for example, when water and chemicals are mixed and flowed upstream of the static mixer, if the mixing ratio of the chemicals temporarily increases, it passes through the static mixer with the concentration partially increased in the flow path. To do. At this time, even if the water and the chemical solution were homogenized in the radial direction and the water and the chemical solution were stirred, the portion where the concentration was partially increased in the flow path in the axial direction (flow direction) became almost undiluted. It flows to the downstream side in the state (see FIG. 22B). As a result, when connected to a semiconductor cleaning device, especially a device that directly applies chemicals to the surface of a semiconductor wafer and performs various treatments, chemicals with different concentrations are applied to the surface of the semiconductor wafer, causing a defective product. There was a problem.

  As a method of avoiding this uneven concentration distribution in the axial direction (flow direction), a tank is installed in the middle of the flow path, the fluid is temporarily stored in the tank, and the concentration in the tank is made uniform. The method of flowing (not shown) etc. are mentioned. However, the installation of the tank requires a large space and the equipment becomes large, and the transport of the fluid from the tank again requires a pump, piping, etc. There was a problem that the cost for constructing the piping line occurred. In this method, fluid stays in the tank. When the fluid stays, bacteria are generated, and the bacteria generated in the tank flow into the piping line, and in the semiconductor manufacturing line, there is a problem that adheres to the semiconductor wafer and causes defective products.

  The object of the present invention has been made in view of the above-mentioned problems of the prior art, and it is possible to uniformly mix the concentration distribution and temperature distribution in the flow direction of the fluid evenly, and to have a compact static fluid mixing And a device using a static fluid mixer.

  The static fluid mixer according to the present invention includes a zigzag-shaped first zigzag channel and a second zigzag channel formed so as to face each other, and a plurality of zigzag channels in the flow direction through the first zigzag channel and the second zigzag channel.

  Hereinafter, embodiments of the present invention will be described with reference to examples shown in the drawings. However, it is needless to say that the present invention is not limited to the examples.

-First embodiment-
Hereinafter, with reference to FIGS. 1-5, the static fluid mixer which is 1st embodiment of this invention is demonstrated. FIG. 1 is a perspective view showing a schematic configuration of a static fluid mixer according to a first embodiment. This static fluid mixer has a mixing channel for mixing different fluids. The mixing channel is formed by, for example, a tube made of PFA (tetrafluoroethylene / perfluoroalkyl vinyl ether copolymer resin). Note that the mixing channel can be formed of other materials such as metal piping.

  The static fluid mixer includes a first zigzag channel 5 and a second zigzag channel 6 formed to face each other, and a plurality of first zigzag channel 5 and second zigzag channel 6 at a plurality of locations in the flow direction. A plurality of branch channels 7 a to 7 h as communication channels to communicate with each other, a first channel 2 connected to an end of the first zigzag channel 5, and a first channel connected to an end of the second zigzag channel 6. And two flow paths 4. A fluid inlet 1 is provided at one end of the first channel 2, and the first channel 2 and the fluid inlet 1 constitute a fluid inlet. A fluid outlet 3 is provided at one end of the second channel 4, and the second channel 4 and the fluid outlet 3 constitute a fluid outlet.

  The first zigzag channel 5 and the second zigzag channel 6 have the same shape as each other, and are arranged in parallel at a certain distance in the height direction (Z direction in the figure). That is, the first zigzag channel 5 and the second zigzag channel 6 are zigzag alternately from one side to the other in the width direction (X direction in the figure) and the other from the other in the width direction via the bent portions 5a and 6a, respectively. The bent portion 5a of the first zigzag channel 5 and the bent portion 6a of the second zigzag channel 6 formed in the longitudinal direction (Y direction in the figure), that is, extending in the XY plane and located at the same position in the longitudinal direction, They are formed in the same direction. The branch flow paths 7 a to 7 h are provided substantially perpendicularly and substantially linearly to the first zigzag flow path 5 and the second zigzag flow path 6, respectively, and are equidistant over the length of the zigzag flow paths 5 and 6. Is arranged. The other end of the first zigzag channel 5 (opposite side of the fluid inlet 1) and the other end of the second zigzag channel 6 (opposite side of the fluid outlet 3) are connected via a branch channel 7h. .

  Next, the operation of the static fluid mixer according to the first embodiment of the present invention will be described.

  When water and a chemical solution are mixed on the upstream side of the static fluid mixer and are flowed in a state in which the concentration of the chemical solution is temporarily increased, the chemical solution that is partially concentrated in the flow path flows into the fluid inlet 1. Flows into the first flow path 2 and flows into the first zigzag flow path 5. When the chemical solution that is partially concentrated and flows through the portion where the branch channel 7a of the first zigzag channel 5 is connected, a part of the drug solution flows through the branch channel 7a and passes through the second zigzag channel 6. And flows from the second flow path 4 to the fluid outlet 3. The remaining chemical liquid flows to the downstream side of the first zigzag flow path 5, and a part of the remaining chemical liquid flows at a point where the concentration of the remaining chemical liquid partially flows and flows through the place where the branch flow path 7b is connected. Flows through the branch flow path 7b, passes through the second zigzag flow path 6, and flows from the second flow path 4 to the fluid outlet 3. The remaining chemical liquid flows to the downstream side of the first zigzag flow path 5, and the remaining chemical liquid that is partially concentrated is connected to the branch flow path 7c in the same manner as the chemical liquid that flows through the branch flow path 7b. At the time of flowing through the portion, a part of the flow flows through the branch flow path 7 c, flows through the second zigzag flow path 6, and flows from the second flow path 4 to the fluid outlet 3. Thereafter, the remaining chemical liquid that is partially concentrated and flows in the same manner as the branch flow paths 7a, 7b, and 7c flows from the second flow path 4 through the second zigzag flow path 6 through the branch flow paths 7d to 7h. It flows to the fluid outlet 3.

  At this time, the partially concentrated chemical liquid flowing through the branch flow path 7a flows out from the fluid outlet 3 earlier than the other partially concentrated chemical liquid flowing, and the branched flow paths 7b and 7c are time-dependent. , 7d, 7e, 7f, 7g, and 7h, part of the flowing chemical solution flows out from the fluid outlet 3 partly in order. In other words, the chemical liquid that is partially concentrated in the flow path flows by being divided into 8 by the time difference by the static fluid mixer, and the fluid flows by being mixed with the chemical liquid that is not concentrated in concentration. The density distribution in the direction can be evenly mixed without any unevenness. At this time, if the inner diameters of the respective branch flow paths are substantially the same, the concentration of the chemical is partially increased and the flowing chemical is divided into approximately eight equal parts, so that the concentration distribution in the fluid flow direction is made more uniform and uniform. Can be mixed.

  In FIG. 1, the branch flow paths 7a to 7h are provided at equal distances from the ends of the first and second zigzag flow paths 5 and 6, but the fluid flowing through each branch flow path 7a to 7h is used. In order to adjust the time difference to be applied, the positions where the branch channels 7a to 7h are provided are freely set, or the first and second zigzag channels 5 and 6 are respectively connected to the first channel 2 and the second channel 4. You may form so that a flow-path cross-sectional area may become small gradually toward the other end part (branch flow path 7h side) from the connected one end part (branch flow path 7a side). The number of branch flow paths 7a to 7h is not particularly limited. By providing a larger number of the branch flow paths 7a to 7h, the concentration distribution in the fluid flow direction can be made more uniform and uniform without unevenness.

  Here, an explanation will be given of the operation in which the concentration distribution in the flow direction of the fluid is made uniform evenly by dividing the chemical solution that is partially concentrated and flowing with the static fluid mixer. As shown in FIG. 2, in the line in which the static fluid mixer of FIG. 1 is arranged on the downstream side of the merging portion of the lines through which the two substances, pure water and the chemical solution, flow, the static fluid mixer of FIG. Concentration meters 57 and 58 are installed on the upstream side and the downstream side, respectively, and a device for mixing and flowing pure water and chemical solution from the upstream side is created, and instantaneously in the middle of flowing pure water and chemical solution at a certain ratio After increasing the concentration of the chemical solution (increasing the ratio of the chemical solution with respect to pure water), the upstream side and the downstream side when the concentration distribution becomes uneven by returning to the original constant ratio. The concentration is measured as shown in FIGS.

  FIG. 3 shows the characteristics obtained by the densitometer 57 installed on the upstream side of the static fluid mixer. The horizontal axis is the elapsed time, and the vertical axis is the concentration. When the concentration becomes high for a certain time, a peak (h1) as shown in the figure appears. FIG. 4 shows the characteristics obtained by the densitometer 58 installed downstream of the static fluid mixer. In the figure, the concentration peaks are dispersed into eight, and the height of the peak (h2) is about one-eighth. The interval t1 between the peaks of the concentration corresponds to the time from when the fluid passes through the position of the branch channel 7a in the first zigzag channel 5 to the branch channel 7b. From the channel 7b to the branch channel 7c, t3 from the branch channel 7c to the branch channel 7d, t4 from the branch channel 7d to the branch channel 7e, t5 from the branch channel 7e to the branch channel 7f, t6 Corresponds to the time from the branch channel 7f to the branch channel 7g, and t7 corresponds to the time from the branch channel 7g to the branch channel 7h.

  At this time, by changing the length of each of the first zigzag channels 5 up to the branch channels 7a to 7h, the intervals t1 to t7 at which the peaks (h2) appear can be changed, and the branch channels 7a When the number of ˜7h is further increased, the height of the peak (h2) can be suppressed to a height that is divided by the number of branch channels with respect to the upstream peak (h1). If a static fluid mixer is not installed, the concentration peak shown in FIG. 3 may be slightly lowered depending on the fluid flow, but the peak (h1) appears almost unchanged. Further, in the first and second zigzag flow paths 5 and 6, the chemical solution is agitated by the change in the zigzag flow direction and the branching / merging of the fluid, so that mixing in the radial direction is performed simultaneously with the flow direction.

  In the present embodiment, the unevenness of the concentration distribution is described. However, the same effect can be obtained for the uniform flow direction of the temperature distribution when hot water and cold water are mixed. For the purpose of uniforming the temperature distribution, it can also be used in hot water heaters, etc., and by making the flow direction of the fluid partially heated in the flow path uniform, the temperature becomes more stable, It is possible to prevent the occurrence of burns caused by the flow of water. In addition, in the case of waste liquid treatment, etc., when the concentration change suddenly disturbs the treatment or when the concentration exceeds a certain level, the static fluid mixer of this embodiment is applied. Thus, the concentration in the flow direction can be made uniform, and stable drainage treatment can be performed.

  The fluid flowing through the static fluid mixer may be a gas. For example, in the purification of automobile exhaust gas, if the exhaust gas concentration suddenly increases when the engine is started or accelerated, the load on the catalyst for purification may increase and the purification capacity may decrease. By applying the static fluid mixer of the present embodiment to the line, the concentration in the flow direction can be made uniform, and the exhaust gas can always be stably purified. Further, the flow of the static fluid mixer repeats branching and merging, so that mixing is performed not only in the flow direction but also in the radial direction. In the present embodiment, the fluid inlet 1 and the fluid outlet 3 are used as the fluid inlet and the fluid outlet, respectively. However, the same effect can be obtained by flowing the fluid in the opposite direction. In this case, the fluid outlet 3 becomes a fluid inlet and the fluid inlet 1 becomes a fluid outlet.

  The static fluid mixer may be provided with zigzag folding reversed as shown in FIG. That is, the bending portions of the first zigzag channel 12 and the second zigzag channel 13 at the same position in the longitudinal direction may be opposite to each other. In FIG. 5, the first zigzag flow path 12 and the second zigzag flow path 13 that are folded in the opposite directions at this time are arranged at a predetermined interval so that the flow paths of the respective straight portions are parallel to each other. The first flow path 9 connected to the fluid inlet 8 and the first flow path 9 connected to the fluid inlet 8 are connected to one end of the first zigzag flow path 12, and the fluid outlet 10 from which the fluid flows out and the second flow path 11 connected to the fluid outlet 10. Is connected to one end of the second zigzag channel 13. Further, on the first zigzag flow path 12, a plurality of branch flow paths 14 respectively connected to arbitrary positions on the second zigzag flow path 13 are provided at equal intervals. A branch channel 14 is also connected to the other end of the first zigzag channel 12 and the second zigzag channel 13. That is, the plurality of branch channels 14 branch from different positions on the first zigzag channel 12 and are connected to the second zigzag channel 13 at different positions on the second zigzag channel 13.

  In FIGS. 1 and 5, the plurality of branch channels 7 a to 7 h and 14 may be connected to positions eccentric to the axes of the first zigzag channels 5 and 12, respectively, and the second zigzag channel 6 , 13 may be connected to positions eccentric to the axis. That is, the extension of the central axis of the branch channels 7a to 7h, 14 (the axis passing through the center of the channel cross-sectional area) does not intersect the center axis of the first zigzag channels 5, 12, and the second zigzag channel 6 , 13 may be provided with branch channels 7a to 7h, 14 so as not to intersect with the central axis of 13. At this time, the chemical solution generates a swirling flow along the inner walls of the first and second zigzag channels 5, 6, 12, and 13. Since the chemical solution is agitated, radial mixing is performed. Further, by generating a swirling flow in the flow path, dead space in the flow path can be eliminated and fluid retention can be prevented.

  FIG. 23 is a comparative example of the present embodiment and shows another method for avoiding uneven density distribution in the axial direction (flow direction). FIG. 23 shows a branch dilution apparatus that diverts a fluid by branching a flow path. This apparatus is an apparatus for analyzing a sample solution flowing through a narrow tube 161 at a constant speed, and a sample solution is provided by providing a branching portion 162 for branching the flowing sample into a plurality of channels in the middle of the channel. , The inner diameters and lengths of the narrow tubes 163 and 164 of each branch flow path are changed and merged again at the merge section 166 in front of the detector 165, and diluted using the time difference at which the sample solution is detected.

  However, when the technique of the branch dilution apparatus shown in FIG. 23 is used for the fluid transport pipe, it is necessary to provide a pipe line that is branched in the middle of the pipe and has a different length and is joined again. For this reason, in order to make the concentration distribution in the axial direction (flow direction) uniform in the flow path without unevenness, it is necessary to provide many branched flow paths, and in that case, a large space is required for providing branched piping lines. There is a problem of becoming. Moreover, in order to construct such a piping line, a large number of parts are required, and there is a problem that it is complicated and takes time. In this respect, in the present embodiment, a large space for providing piping is not required, piping can be easily implemented, and piping can be performed in a short time.

-Second embodiment-
Next, with reference to FIGS. 6-8, the static fluid mixer which is 2nd embodiment of this invention is demonstrated. FIG. 6 is an exploded perspective view showing a schematic configuration of the static fluid mixer according to the second embodiment, and FIG. 7 is an AA longitudinal sectional view of FIG. In the second embodiment, the main body portion 21 and a pair of side plates (first side plate 25 and second side plate 28) attached to both surfaces of the main body portion 21 form a mixing channel similar to FIG. .

  The main body 21 is made of PTFE (polytetrafluoroethylene), for example, and has a substantially rectangular parallelepiped shape as a whole. A zigzag-shaped first zigzag groove 22 and a second zigzag groove 23 are provided in parallel to each other on both surfaces of the main body 21. The first zigzag groove 22 and the second zigzag groove 23 have the same shape as each other, and are formed in parallel so as to face each other across the bottom plate part 21a in the center in the height direction (thickness direction) of the main body part 21. . That is, the folding directions of the zigzag grooves 22 and 23 are the same as those shown in FIG. A plurality of through holes (communication holes 24) are opened at equal intervals along the zigzag grooves 22 and 23 in the bottom plate portion 21 a of the main body portion 21. These communication holes 24 are provided substantially perpendicular to the bottom surfaces of the zigzag grooves 22 and 23, that is, perpendicularly or substantially perpendicularly.

  The first side plate 25 and the second side plate 28 are made of, for example, PP (polypropylene), and are formed in a substantially rectangular shape so as to cover the zigzag grooves 22 and 23 according to the shape of the main body 21. A fluid inlet 26 is provided on the surface of the first side plate 25, and the fluid inlet 26 communicates with a first flow path 27 that penetrates the first side plate 25. A fluid outlet 29 is provided on the surface of the second side plate 28, and the fluid outlet 29 communicates with a second flow path 30 that penetrates the second side plate 28.

  The first side plate 25 and the second side plate 28 are fixed by, for example, bolts and nuts, in close contact with the surface of the main body 21. In this fixed state, the end of the first flow path 27 faces the terminal center axis of the first zigzag groove 22, and the end of the second flow path 30 faces the terminal center axis of the second zigzag groove 23. is doing. By sandwiching the main body portion 21 between the first side plate 25 and the second side plate 28, a first zigzag channel 31 is formed between the first zigzag groove 22 and the first side plate 25 of the main body portion 21, and the main body portion 21. A second zigzag channel 32 is formed between the second zigzag groove 23 and the second side plate 28. The first zigzag flow path 31 and the second zigzag flow path 32 communicate with each other through the communication holes 24. The end of the first zigzag channel 31 communicates with the fluid inlet 26 via the first channel 27, and the second zigzag flow located on the opposite side of the end of the first zigzag channel 31 with the bottom plate portion 21a interposed therebetween. A terminal portion of the path 32 communicates with the fluid outlet 29 via the second flow path 30.

  The first side plate 25 and the second side plate 28 may be joined by any method as long as the first side plate 25 and the second side plate 28 are joined in close contact with the main body 21, and an O-ring may be used as a sealing method. A fitting part may be provided in the edge part of the side plate 25 and the 2nd side plate 28, and the main-body part 21 may be fitted to this fitting part. The fixing method may be other than bolts and nuts, for example, shrink fitting, welding or adhesion.

  The communication holes 24 are preferably formed so that their cross-sectional areas are substantially the same, that is, the same or substantially the same. As a result, the flow rate of the fluid divided by the respective communication holes 24 is kept constant, and the fluid flowing into the static fluid mixer is divided approximately equally by the number of the communication holes 24 to join each other with a time difference. As a result, the concentration distribution can be made uniform without unevenness.

  The fluid flowing through the first zigzag flow path 31 may be subjected to pressure loss due to the fluid being divided from each communication hole 24, and the flow velocity on the downstream side of the first zigzag flow path 31 may be reduced. Therefore, it is preferable that the first zigzag flow path 31 is formed so that the cross-sectional area of the passage gradually decreases from one end connected to the first flow path 27 toward the other end in the flow direction. Thus, by gradually reducing the passage cross-sectional area of the first zigzag channel 31, the fluid flows at a constant speed even if pressure loss occurs, and the time difference between the divided and flowing fluids can be stabilized.

  Similarly, the second zigzag channel 32 is preferably formed so that the passage cross-sectional area gradually decreases from one end connected to the second channel 30 toward the other end. As a result, the fluid flowing from the first zigzag flow path 31 to the second zigzag flow path 32 via the first communication hole 24 is quickly discharged via the fluid outlet 29 and goes downstream of the first zigzag flow path 31. Accordingly, the flow rate of the fluid flowing through the second zigzag channel 32 via the communication hole 24 can be gradually decreased, and the time difference of the fluid can be made clearer. In order to reduce the passage cross-sectional area of the zigzag channels 31, 32, the widths of the first and second zigzag grooves 22, 23 are formed to be gradually narrowed, or the depth is formed to be gradually shallow ( The zigzag grooves 22 and 23 may be formed by combining these (not shown).

  As shown in FIG. 8, the static mixer element 16 may be disposed in the second flow path 15. The static mixer element 16 includes a plurality of twisted plates that are alternately twisted in the reverse direction around the flow axis and arranged in series, whereby the second flow channel 15 in which the static mixer element 16 is disposed. When the fluid passes through, the fluid is alternately agitated by reverse rotation along the twisted plate, and radial mixing is performed. As a result, the mixing effect in the radial direction of the static mixer element 16 is added to the mixing effect in the flow direction and the radial direction of the fluid mixer, and the fluid can be mixed more uniformly. In particular, it is suitable for mixing fluids that are viscous and difficult to mix.

  Next, the operation of the static fluid mixer according to the second embodiment of the present invention will be described.

  When water and a chemical solution are mixed on the upstream side of the static fluid mixer and flowed in a state in which the concentration of the chemical solution is temporarily increased, the chemical solution that is partially concentrated in the flow path flows into the fluid inlet 26. And flows into the first zigzag channel 31 through the first channel 27. The chemical liquid flowing in the first zigzag flow path 31 with a partially concentrated concentration flows divided by the communication holes 24 serving as the branch flow paths, and the chemical liquid flowing with the partial concentration increased in a time difference. By flowing through the second zigzag flow path 32 and mixing with the chemical solution that is not concentrated, the liquid is uniformized and mixed in the fluid flow direction, and flows out from the fluid outlet 29 through the second flow path 30. The configuration of the flow path of the second embodiment is the same as that of the first embodiment, and the action of uniformizing the concentration distribution in the fluid flow direction without any unevenness is the same as in the first embodiment. Omitted.

-Third embodiment-
Next, with reference to FIG. 9, FIG. 10, the static fluid mixer which is 3rd embodiment of this invention is demonstrated. FIG. 9 is an exploded perspective view showing a schematic configuration of the static fluid mixer according to the third embodiment, and FIG. 10 is a BB longitudinal sectional view of FIG. The third embodiment is the same as the second embodiment except that the installation locations of the fluid inlet 38 and the fluid outlet 41 are different from those of the second embodiment.

  That is, a first zigzag groove 34 is provided on one end surface of the PTFE main body portion 33, and a second zigzag groove 35 is provided on the other end surface of the main body portion 33. The first zigzag groove 34 and the second zigzag groove 35 are provided in parallel on both sides of the plate, and are formed so that the folding direction is the same and the flow paths of the respective straight portions are parallel. The first zigzag groove 34 is provided with communication holes 36 at equal intervals on the bottom surface of the first zigzag groove 34, which serve as a plurality of branch channels communicating with the bottom surface of the second zigzag groove 35. A fluid inlet 38 and a fluid outlet 41 are juxtaposed on the side surface of the main body 33. The fluid inlet 38 communicates with the first flow path 39 that penetrates the side end of the main body 33, and the fluid outlet 41 communicates with the second flow path 42 because it penetrates the side end of the main body 33.

  The first side plate 37 and the second side plate 40 made of PP are formed in the same shape as the main body 33. The first side plate 37 and the second side plate 40 are fixed by bolts and nuts while being in close contact with both surfaces of the main body portion 33. By sandwiching the main body portion 33 between the first side plate 37 and the second side plate 40, a first zigzag channel 43 is formed between the first zigzag groove 34 and the first side plate 37 of the main body portion 33, and the main body portion 33. A second zigzag channel 44 is formed between the second zigzag groove 35 and the second side plate 40. The first zigzag channel 43 and the second zigzag channel 44 communicate with each other through the communication holes 36. The end of the first zigzag channel 43 communicates with the fluid inlet 38 via the first channel 39, and the end of the second zigzag channel 44 located on the opposite side of the end of the first zigzag channel 43 is The fluid outlet 41 communicates with the second flow path 42.

  Next, the operation of the static fluid mixer according to the third embodiment of the present invention will be described.

  When water and a chemical solution are mixed on the upstream side of the static fluid mixer and flowed in a state where the concentration of the chemical solution is temporarily increased, the chemical solution that is partially concentrated in the flow path flows into the fluid inlet 38. And flows into the first zigzag channel 43 through the first channel 39. The chemical liquid that is partially concentrated and flows through the first zigzag channel 43 flows in a divided manner through the communication holes 36 that form the respective branch channels. For this reason, the chemical solution that is partially concentrated in concentration flows through the second zigzag flow path 44 with a time difference and mixes with the non-concentrated chemical solution, and is uniformly mixed in the fluid flow direction. The mixed fluid flows out from the fluid outlet 41 through the second flow path 42. The configuration of the flow path of the third embodiment is the same as that of the second embodiment, and the action of uniformizing the concentration distribution in the fluid flow direction without any unevenness is the same as that of the second embodiment, so the description is omitted. To do.

-Fourth embodiment-
Next, a static fluid mixer according to a fourth embodiment of the present invention will be described with reference to FIGS. FIG. 11 is an exploded perspective view showing a schematic configuration of a static fluid mixer according to the fourth embodiment, and FIG. 12 is a CC longitudinal sectional view of FIG. The fourth embodiment differs from the third embodiment in that zigzag grooves 46 and 47 are provided inside the side plates 49 and 52 instead of the main body portion 45.

  The first side plate 49 and the second side plate 52 of the fourth embodiment are each made of PTFE. A first zigzag groove 46 is provided on the inner surface of the first side plate 49, and a fluid inlet 50 is provided on one side surface of the first side plate 49. The fluid inlet 50 communicates with the first flow path 51 that faces the first zigzag groove 46 and penetrates the side end portion of the first side plate 49. Similarly, a second zigzag groove 47 is provided on the inner surface of the second side plate 52, and a fluid outlet 53 is provided on one side surface of the second side plate 52. The fluid outlet 53 communicates with the second flow path 54 that faces the second zigzag groove 47 and penetrates the side end portion of the second side plate 52. Note that the first zigzag groove 46 and the second zigzag groove 47 are formed such that when facing each other, the folding direction is the same and the flow paths of the respective linear portions are parallel.

  The main body 45 is made of PP and has a plate shape. The first side plate 49 and the second side plate 52 are fixed to both surfaces of the main body 45 with bolts and nuts (not shown) in close contact with each other. By sandwiching the main body 45 between the first side plate 49 and the second side plate 52, a first zigzag channel 55 is formed between the first zigzag groove 46 of the first side plate 49 and the main body 45, and the second side plate A second zigzag channel 56 is formed between the second zigzag groove 47 and the main body 45. A plurality of through holes (communication holes 48) are opened at equal intervals over the length of the channel at a position facing the first zigzag channel 55 and the second zigzag channel 56. The flow path 55 and the second zigzag flow path 56 communicate with each other through a communication hole 48.

  Next, the operation of the static fluid mixer according to the fourth embodiment of the present invention will be described.

  When water and a chemical solution are mixed on the upstream side of the static fluid mixer and flowed in a state where the concentration of the chemical solution is temporarily increased, the chemical solution that is partially concentrated in the flow path flows into the fluid inlet 50. And flows into the first zigzag channel 55 through the first channel. The chemical liquid flowing in the first zigzag channel 55 with a partially concentrated concentration flows divided by the communication holes 48 serving as the respective branch channels, and the chemical solution flowing with the partially concentrated flow passes through the second time difference. By flowing through the zigzag flow path 56 and mixing with the liquid chemicals that are not concentrated, the liquid is made uniform in the fluid flow direction and flows out from the fluid outlet 53 through the second flow path. The effect of uniformizing the concentration distribution in the flow direction of the fluid in the fourth embodiment without unevenness is the same as in the third embodiment, and thus the description thereof is omitted.

  In the present embodiment, the first zigzag groove 46 is formed in the first side plate 49 and the second zigzag groove 47 is formed in the second side plate 52, and the communication hole 48 communicating with these is provided in the main body 45. For this reason, by replacing the main body 45 in which the number and arrangement of the communication holes 48 are changed, the uniformity of the fluid flow direction can be changed and adjusted depending on the application. In the second, third, and fourth embodiments, the first and second zigzag flow paths are formed with the zigzag folding direction being the same direction, but the zigzag folding directions may be opposite to each other.

  In the second, third, and fourth embodiments, square plates are attached to both sides of the main body to form the first and second zigzag flow paths, but rectangular and circular plates may be used. The cross-sectional shape of the part may be other than a rectangular shape. For example, a curved zigzag groove may be formed in accordance with the shape of the main body. The first and second zigzag flow paths may be formed in accordance with the installation space, so that the situation of the installation location can be flexibly handled. Since the zigzag groove has a shape that is easy to cut even with a small size, it can be easily manufactured with a small diameter.

-Fifth embodiment-
Hereinafter, a static fluid mixer according to a fifth embodiment of the present invention will be described with reference to FIG. FIG. 13 is a perspective view showing a schematic configuration of a static fluid mixer according to a fifth embodiment. In the fifth embodiment, as in the first embodiment, a static fluid mixer is configured by pipe-connecting tubes or the like, for example.

  The static fluid mixer according to the fifth embodiment includes a fluid inlet 61 into which fluid flows, a linear first flow path 62 connected to the fluid inlet 61, a fluid outlet 63 from which fluid flows out, and a fluid outlet. 63, a linear second flow path 64 parallel to the first flow path 62, a first zigzag flow path 65 connected to the end of the first flow path 62, and an end of the second flow path 64 And a second zigzag channel 66 connected thereto. The first zigzag channel 65 and the second zigzag channel 66 are each extended in a zigzag longitudinal direction in the circumferential direction so as to be a semi-cylindrical shape in which the cylinder is vertically divided in the longitudinal direction. Symmetrically with respect to each other.

  A plurality of substantially straight branching channels 67a to 67h are connected to the first zigzag channel 65 and the second zigzag channel 66 at the center in the circumferential direction of the zigzag channels facing each other. These branch flow paths 67a to 67h are provided in parallel to each other, and the first zigzag flow path 65 and the second zigzag flow path 66 are communicated at a plurality of locations via the branch flow paths 67a to 67h. One end of the branch channel 67 h is connected to the other end of the first zigzag channel 65, and the other end of the branch channel 67 h is connected to the other end of the second zigzag channel 66. That is, the plurality of branch channels 67 a to 67 h are branched from different positions on the first zigzag channel 65 and connected to the second zigzag channel 66 at different positions on the second zigzag channel 66. .

  Next, the operation of the static fluid mixer according to the fifth embodiment of the present invention will be described.

  When water and a chemical solution are mixed on the upstream side of the static fluid mixer and flowed in a state where the concentration of the chemical solution is temporarily increased, the chemical solution that is partially concentrated in the flow path flows into the fluid inlet 61. Flows into the first flow path 62 and flows into the first zigzag flow path 65. When the chemical solution that is partially concentrated and flows through the portion where the branch channel 67a of the first zigzag channel 65 is connected, a part of the chemical flows through the branch channel 67a and passes through the second zigzag channel 66. And flows from the second flow path 64 to the fluid outlet 63. The remaining chemical liquid flows to the downstream side of the first zigzag flow path 65, and a part of the remaining chemical liquid flows at a point where the concentration of the remaining chemical liquid partially flows and flows through the place where the branch flow path 67b is connected. Flows through the branch flow path 67b, passes through the second zigzag flow path 66, and flows from the second flow path 64 to the fluid outlet 63. The remaining chemical liquid flows to the downstream side of the first zigzag flow path 65, and further, the remaining chemical liquid that is partially concentrated and flows in the branch flow path 67c in the same manner as the chemical liquid that flows through the branch flow path 67b. When it flows through the connected portion, a part thereof flows through the branch channel 67 c and flows from the second channel 64 to the fluid outlet 63 through the second zigzag channel 66. Thereafter, the remaining chemicals that are partially concentrated and flow in the same manner as the branch channels 67a, 67b, and 67c flow through the branch channels 67d, 67e, 67f, 67g, and 67h, and then pass through the second zigzag channel 66. It flows from the second flow path 64 to the fluid outlet 63.

  At this time, a part of the chemical liquid that is partially concentrated in the branch channel 67a flows out from the fluid outlet 63 earlier than the chemical liquid that is partially concentrated and flows. Further, a part of the solution whose concentration is partially increased is a branched flow path 67b, a branched flow path 67c, a branched flow path 67d, a branched flow path 67e, a branched flow path 67f, a branched flow path 67g, or a branched flow with a time difference. A part of the chemical liquid that passes through any of the passages 67h and partially has a high concentration flows out from the fluid outlet 63. In other words, the chemical solution that is partially concentrated in the flow path flows into eight parts by the time difference by the static fluid mixer, and flows by being mixed with the chemical solution that is not concentrated. The concentration distribution in the flow direction can be uniformly mixed without any unevenness. At this time, if the inner diameters of the respective branch flow paths are substantially the same, the chemical solution that is partially concentrated and flows is divided into approximately eight equal parts, so that the concentration distribution in the fluid flow direction is made more uniform and uniform. Can be mixed.

  In FIG. 13, the branch flow paths 67a to 67h are provided at equal intervals along the axis of the cylinder. However, in order to adjust the time difference applied to the fluid flowing through each of the branch flow paths 67a to 67h, the connected positions Can be set freely, or the first zigzag flow path 65 can be formed so that the cross-sectional area of the passage gradually decreases from one end connected to the first flow path 62 to the other end. You may form so that a channel cross-sectional area may become small gradually toward the other end part from the one end part which connected 66 with the 2nd flow path 64. FIG. The number of branch flow paths 67a to 67h is not particularly limited. By providing a larger number of branch flow paths 67a to 67h, the concentration distribution in the fluid flow direction can be made more fine and uniform without unevenness.

-Sixth embodiment-
Next, with reference to FIGS. 14-16, the static fluid mixer which is the 6th embodiment of this invention is demonstrated. In the sixth embodiment, the main body 68 is made of PTFE, and is formed in a substantially columnar shape, that is, a columnar shape or a substantially columnar shape. FIG. 14 is a longitudinal sectional view showing a schematic configuration of a static fluid mixer according to a sixth embodiment, and FIGS. 15A and 15B are a front view and a rear view of the main body of FIG. 14, respectively. It is.

  The outer peripheral surface of the main body 68 is divided into a half-cylindrical portion by dividing the cylinder vertically, a first zigzag groove 73 is provided on one side of the outer peripheral surface, and a second zigzag groove 74 is provided on the other side of the outer peripheral surface. Is provided. These first and second zigzag grooves 73 and 74 are arranged so as to be symmetric with respect to the axis. A plurality of through holes (communication holes 75) are opened at equal intervals in the longitudinal direction from the bottom surface of the first zigzag groove 73 to the bottom surface of the second zigzag groove 74 in the central portion of the main body 68.

  The cylindrical body 76 as a housing is made of PP, for example, and has a substantially cylindrical shape. The cylindrical body 76 has an inner diameter that is substantially the same as the outer diameter of the main body 68, and is fitted and fixed in a state of being sealed to the outer peripheral surface of the main body 68 by shrink fitting. By fitting the cylindrical body 76 to the main body portion 68, a first zigzag channel 77 is formed between the first zigzag groove 73 of the main body portion 68 and the cylindrical body 76, and the second zigzag groove of the main body portion 68 is formed. A second zigzag channel 78 is formed between 74 and the cylindrical body 76.

  The first zigzag channel 77 and the second zigzag channel 78 communicate with each other at a plurality of locations in the longitudinal direction through a plurality of communication holes 75. A fluid inlet 69 and a fluid outlet 71 are provided on the outer peripheral surface of the cylindrical body 76. The fluid inlet 69 is connected to the terminal portion of the first zigzag channel 77 via the first channel 70 that penetrates the cylindrical body 76, and the fluid outlet 71 is connected via the second channel 72 that penetrates the cylindrical body 76. The second zigzag channel 78 is connected to the end portion.

  The cylindrical body 76 as the casing may be fitted by any method as long as it is fitted in a sealed state with the main body 68. As a sealing method, an O-ring or a tube is used. The cylindrical body 76 made of a soft member such as may be used for close contact. In addition to shrink-fitting, joining may be performed by welding or adhesion. Even if the cylindrical body 76 and the main body portion 68 are fixed in a state where the bottomed cylindrical cylindrical body is fitted to the main body portion 68 and the cylindrical body is sealed to the outer peripheral surface of the main body portion 68 by a seal ring. Alternatively, the main body 68 may be screwed into the cylindrical body 76.

  Next, the operation of the static fluid mixer according to the sixth embodiment of the present invention will be described.

  When water and a chemical solution are mixed on the upstream side of the static fluid mixer and flowed in a state where the concentration of the chemical solution is temporarily increased, the chemical solution that is partially concentrated in the flow path flows into the fluid inlet 69. From the first flow path 70 to the first zigzag flow path 77. The partially concentrated chemical solution flowing through the first zigzag channel 77 is divided and flows by the respective communication holes 75, and the partially concentrated chemical solution flowing through the first zigzag channel 77 is secondly zigzag channel 78 with a time difference. Are mixed in the fluid flow direction by mixing with each of the liquid chemicals that are not concentrated. The effect of uniformizing the concentration distribution in the fluid flow direction of the sixth embodiment without any unevenness is the same as that of the fifth embodiment, and thus the description thereof is omitted.

  According to the static fluid mixer of the present embodiment, the communication hole 75 extending from the bottom surface of the first zigzag groove 73 to the bottom surface of the second zigzag groove 74 can be easily formed. For this reason, the installation position and the number of installation of the communication holes 75 can be freely provided, the flow time difference can be adjusted finely and evenly, and the concentration distribution in the fluid flow direction can be made more uniform and uniform. Can do. In addition, the static fluid mixer of this embodiment can be easily manufactured because it is relatively easy to process for the complexity of the flow path and the number of parts is small. Moreover, since the flow path structure is small, the static fluid mixer can be miniaturized and can be installed without taking up piping space. When connecting the static fluid mixer to the piping line, the construction is completed simply by connecting the fluid inlet 69 and the fluid outlet 71 with joints or the like, so that the piping construction is easy and the piping construction is performed in a short time. be able to.

  When manufacturing the main body 68 in the sixth embodiment, the main body 68 is formed by, for example, injection molding. The first zigzag groove 73 and the second zigzag groove 74 of the main body portion 68 do not intersect obliquely with respect to the axis line, for example, like a spiral, and are formed by planes that intersect perpendicularly to the axis line. For this reason, if it forms so that a metal mold | die may be divided by the surface (FIG. 15 (a)) with the folding | turning part of the 1st, 2nd zigzag grooves 73 and 74, and the surface on the opposite side (FIG.15 (b)). The cavity structure in the mold manufacture becomes simple, the mold manufacture is easy, there is no undercut part, and the mold can be easily removed during molding.

  Here, it is desirable that the communication holes 75 are formed so that their passage cross-sectional areas are substantially the same. As a result, the flow rate of the fluid divided by each communication hole 75 flows at a constant value, and the fluid flowing into the static fluid mixer is divided approximately equally by the number of communication holes 75 and merges with a time difference. As a result, the concentration distribution can be made uniform without unevenness.

  In addition, the fluid flowing through the first zigzag flow path 88 may cause a pressure loss due to the fluid being divided and flowing from each communication hole 86, and the flow velocity on the downstream side of the first zigzag flow path 88 may be reduced. Therefore, as shown in FIG. 16, the first zigzag flow path 88 may be formed such that the cross-sectional area of the passage gradually decreases from one end connected to the first flow path 81 toward the other end in the flow direction. preferable. Thus, by gradually reducing the passage cross-sectional area of the first zigzag channel 88, the fluid can flow at a constant speed even if pressure loss occurs, and the time difference between the divided and flowing fluids can be stabilized.

  Similarly, the second zigzag flow path 89 is preferably formed so that the cross-sectional area of the passage gradually decreases from one end connected to the second flow path 83 to the other end. As a result, the fluid flowing from the first zigzag flow path 88 to the second zigzag flow path 89 via the first communication hole 86 is quickly discharged via the fluid outlet 82 and goes downstream of the first zigzag flow path 88. Accordingly, the flow rate of the fluid flowing through the second zigzag channel 89 via the communication hole 86 is gradually decreased, and the time difference between the fluids can be further clarified.

  In FIG. 16, the outer peripheral surface of the main body 79 is the other end from the one end side where the fluid inlet 80 and the fluid outlet 82 are provided as the main body 79 having the bottom surface positions of the first and second zigzag grooves 84 and 85 aligned. The first and second zigzag flow paths 88 and 89 are formed by fitting a cylindrical body 87 that is provided so as to be gradually reduced in diameter toward the side and matching the outer peripheral surface shape. The method of gradually reducing the passage cross-sectional areas of the paths 88 and 89 from the one end connected to the first flow path 81 and the second flow path 83 toward the other end is not limited thereto. For example, the depths of the first and second zigzag grooves 84 and 85 may be gradually reduced (not shown), or the width of the zigzag grooves may be gradually reduced (not shown), or a combination thereof may be used.

The static fluid mixer of the present embodiment is easy to disassemble and assemble, and can be suitably used particularly in the food field where operations of disassembling and cleaning and assembling parts are frequently performed.

  Next, an apparatus using the above static fluid mixer will be described with reference to FIGS.

  The static fluid mixer according to the embodiment of the present invention is applied, for example, in a line in which the temperature or concentration of the fluid changes with time. That is, for example, a heater is installed in the line, and the temperature of the fluid changes with time due to variations in the temperature of the fluid with respect to the time axis heated by this heater, or solid matter immersed in the tank This is applied to the case where the concentration eluted in the line that is eluted into the flow line changes over time, and the temperature or concentration of the fluid in the line can be made uniform by using the inside of the static fluid mixer. In addition, if the substance sent as a fluid is gas or a fluid, it will not specifically limit.

  FIG. 19 is a diagram illustrating an example of an apparatus using the static fluid mixer according to the present embodiment. In the figure, a static fluid mixer 136 is arranged on the downstream side of the merge part 133 of the lines 131 and 132 through which two substances flow. Each substance is supplied by pumps 134 and 135, respectively. For this reason, the mixing ratio when the fluids merge may change over time due to the pulsation of the pumps 134 and 135, etc., but the static fluid mixer 136 makes the mixing ratio of the substance uniform, The temperature and concentration can be made constant with respect to the time axis. In the state where the high temperature fluid and the low temperature fluid are respectively flowed through the lines 131 and 132, for example, when the high temperature fluid flows non-uniformly and the temperature of the fluid varies with respect to the time axis, or the predetermined concentration fluid is changed to other fluids.
