Description

  The present invention relates to a static mixer and a static mixer that are used for effectively stirring a fluid flowing in a flow path of a fluid transport pipe in various industries such as a chemical factory, a semiconductor manufacturing field, a food field, a medical field, and a bio field. The present invention relates to the fluid mixing device used.

  2. Description of the Related Art Conventionally, there is a mixer as shown in FIG. 22 as a static mixer that is attached to a fluid transport pipe and uniformly mixes the fluid flowing in the pipe (see, for example, Patent Document 1). The mixer shown in FIG. 22 includes a joining member 101 obtained by joining two plate-like members 101a and 101b. Each surface of the members 101a and 101b is provided with a zigzag-shaped groove 103 having a through hole 102 serving as an inlet or outlet at one end, and by joining the surfaces provided with the groove 103, Two flow paths 104 are formed in a space formed by the groove 103 surrounded by the members 101a and 101b. Further, the two flow paths 104 are arranged so as to intersect each other.

JP 2008-264640 A

  However, although the conventional mixer joins the surfaces of the two plate-like members 101a and 101b, since the surface of a normal plate material is not completely flat, these surfaces should be joined uniformly. It is difficult to produce a part where the strength of the joint is locally weak, and the surfaces may be easily peeled off. Further, it is difficult to join the members 101a and 101b along the boundary line of the groove 103 serving as the flow path 104. If the joining is insufficient, a gap is formed around the groove 103, and the fluid flows into the gap and stays there. As a result, the flow path 104 may be contaminated. In addition, even if the members 101a and 101b are sufficiently bonded to each other, an adhesive or the like used for bonding may protrude into the flow channel 104 and hinder the flow in the flow channel 104. In particular, in the semiconductor manufacturing field, the food field, the pharmaceutical field, etc., there is a need for a mixer that does not contaminate the flow path 104 caused by the fluid staying in the gap and does not elute the adhesive component from the adhesive that protrudes into the flow path 104. It has been.

  Further, in order to improve the fluid mixing efficiency, it is necessary to extend zigzag grooves 103 provided as flow paths 104 on the surfaces of the plate-like members 101a and 101b on these surfaces while branching and joining them. Therefore, there is a possibility that the length of the mixer becomes long particularly when a fluid that is difficult to mix is mixed. Further, when the flow rate of the fluid to be mixed is increased, it is necessary to increase the cross-sectional area and length of the groove 103. However, as the cross-sectional area and length of the groove 103 increases, the thickness of the bonding member 101 and the bonding between the members 101a and 101b are increased. Since the area of the surface increases, it may be difficult to procure a plate material or to form and process the members 101a and 101b. In many factories such as chemical factories, the flow rate of fluid flowing through the piping line is large, the diameter of the pipe used in the piping line varies, and the pipe is often laid in a narrow space, so it is compact. There is a need for a mixer that is easy to pipe in shape.

  Hereinafter, the static mixer according to the first embodiment of the present invention will be described with reference to FIGS.

  The static mixer has branch points 5a to 5d between an inlet channel 2 having a fluid inlet 1 which is an opening through which fluid flows and an outlet channel 4 having a fluid outlet 3 which is an opening through which fluid flows. And a plurality of mixed cells 8a-d having junction points 6a to 6d and branch channels 7a to 7d that branch and communicate with each other between the branch points 5a to 5d and the junction points 6a to 6d. They are stacked in series via the communication channels 9a to 9c. The inlet flow channel 2 of the static mixer communicates with the branch point 5a of the mixing cell 8a on the most upstream side, and the outlet flow channel 4 communicates with the junction 6d of the mixing cell 8d on the most downstream side. Here, the center points of the fluid inlet 1 and the fluid outlet 3 and all the mixing cells 8 are arranged on the same axis, and the communication channels 9a to 9c connect the center points of the mixing cells 8a to d. It is orthogonal to the axis. Moreover, the inlet channel 2, the branch channels 7a to d, the communication channels 9a to 9c, and the outlet channel 4 are formed in a circular cross section. Moreover, in this embodiment, all the mixing cells 8a-d are formed in the annular shape which has the same outer diameter. 2A, the inclination of each mixing cell 8 with respect to the direction A (that is, the angle of the virtual plane B on which the annular shape of the mixing cell 8 is formed with respect to the direction A) is all the same angle in this embodiment. Is arranged. In FIG. 2A, the direction A is parallel to the axis passing through the center point of each mixing cell 8a-d, but the direction A is the length direction of the static mixer, which is the direction in which the static mixer extends. That's fine. In addition, the state of the static mixer according to the first embodiment is such that at least a part of at least one mixing cell 8 is different from other mixing cells 8 when viewed from a certain direction, particularly from the length direction of the static mixer. It can also be said that they overlap. This also applies to static mixers according to other embodiments described later.

  FIG. 2B shows a view in the direction of arrow A in FIG. 2A. In FIG. 2B, an axis surrounding surface 7ea (indicated by diagonal lines in FIG. 2B) corresponding to a region surrounded by a channel axis 7fa (indicated by dotted lines in FIG. 2B) passing through the cross-sectional center of the branch channel 7 is shown. )It is shown. Here, while considering FIG. 2B, when the static mixer of FIG. 1 is viewed from the direction A, which is the direction that coincides with the length direction of the static mixer, the branch flow paths 7a to d of the respective mixing cells 8a to 8d. Since the axis enclosing surface 7ea is parallel to an axis passing through the center point of each mixing cell 8a-d and each mixing cell 8a-d has the same shape, the entire axis enclosing surface 7ea is mutually connected. It overlaps. However, when the mixing cell 8 is viewed from the length direction of the static mixer, at least a part of the axis enclosing surface 7ea of the branch flow path 7a to d of any mixing cell 8a to d is mixed with another mixing cell 8a to 8a. As long as it is arranged so as to overlap with the axis surrounding surface 7ea of the branch flow paths 7a to d of the d, the mixed cells 8a to 8d may be arranged in a stacked state. As a result, the length of the static mixer can be made compact without expanding in the width direction. In addition, in the case of a static mixer in which three or more branch flow paths 7 exist in one mixing cell 8, the area of the above-described axis surrounding surface 7ea is maximized when viewed from the length direction of the static mixer. As described above, the flow path axis line 7fa that is the outer edge of the axis surrounding surface 7ea is selected.

  In this embodiment, although the shape of the mixing cells 8a to d is an annular shape, the shapes of the mixing cells 8a to 8d are respectively merged with the branch points 5a to d and the merge points 6a to d and the branch points 5a to d. There is no particular limitation as long as it is formed from branch channels 7a to 7d that branch and communicate with the channels between the points 6a to 6d. As the shape of the mixed cells 8a to 8d, in addition to an annular shape such as a circle and an ellipse, and a polygon such as a triangle and a quadrangle, for example, a shape obtained by combining an annular shape and a polygon, a partial or overall twist, Examples of the shape include bending or meandering. Moreover, in this embodiment, although the magnitude | size of each mixing cell 8a-d is arrange | equalized, it does not specifically limit also about the magnitude | size of mixing cell 8a-d, Each mixing cell 8 is made into a different magnitude | size. It may be formed. In the present embodiment, the mixing cells 8a to 8d are formed so as to have a circular shape with the same outer diameter, thereby facilitating the forming process of the mixing cells 8a to 8d and the assembly of the static mixer.

  Moreover, in this embodiment, although the inclination of all the mixing cells 8a-d with respect to the direction A is equal, this inclination is with the virtual plane B in which the annular shape of the direction A and the mixing cells 8a-d is formed. Need only intersect and have an angle, and is not particularly limited to the configuration of the present embodiment. Moreover, each mixing cell 8a-d may be arrange | positioned how it is laminated | stacked, and it does not specifically limit. In the present embodiment, the mixing cells 8a to 8d are stacked so that the center points of all the mixing cells 8a to 8d are arranged on the same axis. By arranging the mixing cells 8a to 8d in this way, the mixing cells 8a to 8d can be regularly stacked, and the static mixer can be formed compactly. Furthermore, the static mixer can be made more compact by aligning the center point, shape and angle of each mixing cell 8a-d, and accessories such as a heat insulating cover and a protective cover can be easily attached to the outer peripheral surface. It becomes like this.

  Further, the fluid inlet 1 and the fluid outlet 3 of the static mixer may be formed anywhere as long as they are the outer peripheral surface of the static mixer, and are not particularly limited. In this embodiment, the fluid inlet 1 and the fluid outlet 3 are provided on both end faces of the static mixer, and the center point of the fluid inlet 1 and the fluid outlet 3 is an axis connecting the center points of the mixing cells 8a to 8d. They are arranged on the same axis. By forming the fluid inlet 1 and the fluid outlet 3 in this way, the static mixer can be made into a straight shape, and the static mixer can be attached to the straight pipe portion that occupies most of the piping line. Can be easily installed in the line.

  In the present embodiment, the length and thickness of the inlet channel 2, the branch channels 7a to d, the communication channels 9a to 9c, and the outlet channel 4 are the same. The thickness may be changed and is not particularly limited. Moreover, in this embodiment, the branched flow paths 7a-d of the mixing cells 8a-d are branched at the same branch points 5a-d and merged at the same merge points 6a-d. It may branch at different branch points 5a to 5d for each of 7a to 7d or join at different junctions 6a to 6d, and is not particularly limited.

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

  When the pipe that flows water and the pipe that flows chemical solution are joined upstream from the static mixer, and the chemical liquid in which water and chemical liquid are mixed non-uniformly is flowed to the static mixer, the concentration is partially increased in the flow path. The chemical liquid that is flowing thickly flows into the inlet channel 2 from the fluid inlet 1. When the chemical solution reaches the branch point 5a of the mixing cell 8a from the inlet channel 2, the chemical solution is branched and flows into the branch channel 7a. When the chemical liquid flowing through the branch flow path 7a reaches the confluence 6a, the chemical liquid collides and merges while being stirred, flows into the communication flow path 9a, and flows downstream. When the chemical liquid flowing through the communication channel 9a reaches the branch point 5b of the next mixing cell 8b, the chemical liquid is branched in the same manner as when flowing through the branch point 5a, and reaches the junction 6b via the branch channel 7b. Collide and join together while being agitated and flow into the communication channel 9b and flow downstream. Similarly to the mixing cells 8a and 8b and the communication channels 9a and 9b, the chemical liquid flowing through the communication channel 9b flows into the mixing cell 8d through the mixing cell 8c and the communication channel 9c, and reaches the junction 6d of the mixing cell 8d. To do. The chemical solution that has reached the junction 6d is repeatedly stirred and mixed at the junctions 6a to 6d of the four mixing cells 8a to 8d, so that the concentration in the channel becomes uniform, and the fluid outlet 3 passes through the outlet channel 4. Out of the static mixer.

  In the present embodiment, the communication channels 9a to 9c are connected to the junctions 6a to 6d of the mixing cells 8a to 8d and the branch points 5b to 5d of other mixing cells 8b to 8d adjacent to the downstream side of the mixing cells 8a to 8d. Are communicated with each other at the shortest distance and perpendicular to the axis connecting the center points of the mixing cells 8a to 8d, but the communication channels 9a to 9c communicate with the adjacent mixing cells 8a to 8d. There is no particular limitation as long as it is. When the communication channel 9 is formed such that the angle formed by the communication channels 9a to 9c and the axis connecting the central points of the mixing cells 8a to 8d is inclined from 90 ° to the upstream side, the length of the communication channel 9 is obtained. The interval between the adjacent mixing cells 8a to 8d can be narrowed while securing the static mixer, and the static mixer can be formed more compactly. Further, as shown in FIG. 3, the communication channels 9 a to 9 c may be formed so as to be parallel to the axis connecting the center points of the mixing cells 8 a to d. When formed in this way, when the mixing cells 8a to 8d are communicated with each other, the communication flow easily occurs on the outer peripheral side of the mixing cells 8a to 8d without using the oblique communication channels 9a to 9c that are difficult to assemble and process. Paths 9a-c can be formed. It is particularly suitable when the lengths of the communication channels 9a to 9c do not have a great influence on mixing the chemical solution flowing through the static mixer. In addition, when the communication channels 9a to 9c having a length sufficient to mix the chemical liquid that has collided and stirred at the junctions 6a to 6d are necessary, the communication channels 9a to 9c may be formed in a spiral shape. At this time, if the communication channels 9a to 9c are formed so that the channel central axes of the communication channels 9a to 9c are parallel to the axis connecting the center points of the mixing cells 8a to 8d, the length of the communication channels 9a to 9c is increased. The static mixer can be made compact while increasing the length. Further, when it is desired to further stir the chemical liquid that has collided and stirred at the junctions 6a to 6d in the communication flow paths 9a to 9c, the communication flow paths 9a to c are meandered to flow the chemical liquid in the communication flow paths 9a to 9c. The communication channels 9a to 9c may be formed so that the direction changes.

  In the present embodiment, the inlet channel 2 having the fluid inlet 1 and the outlet channel 4 having the fluid outlet 3 are arranged so as to communicate with the mixing cell 8a on the most upstream side and the mixing cell 8d on the most downstream side, respectively. However, as shown in FIG. 4, the fluid inlet 1 and the fluid outlet 3 may be formed directly on the mixing cells 8 a and 8 d without forming the inlet channel 2 and the outlet channel 4. Moreover, in this embodiment, although the adjacent mixing cells 8a-d are mutually connected by the communication flow paths 9a-c, as shown in FIG. 4, adjacent mixing cells 8a-d are communication flow paths 9a-c. You may arrange | position so that it may communicate without going through.

  Further, in the present embodiment, the branch points 5a to d and the merge points 6a to d of the mixing cells 8a to d are arranged at opposing positions on the mix cells 8a to d, but the branch point 5 and the merge point 6 are It may be arranged anywhere as long as it is on the mixed cell 8, and is not particularly limited. As shown in FIG. 5, the branch point 5 and the junction 6 may be arranged at different positions for each mixing cell 8.

  In the present embodiment, there are two branch channels 7a to 7d that branch the channel from the branch points 5a to 5d, but the number of each of the branch channels 7a to 7d is not particularly limited. As shown in FIG. 6, the number of branch flow paths 7 may be different for each mixing cell 8.

  The chemical liquid that has flowed into the inlet channel 2 from the fluid inlet 1 flows into the mixing cell 8 and flows into the branch channel 7 via the branch point 5. When the branch channel 7 reaches the junction 6, the branched chemical solution is collided and mixed and flows into the communication channel 9. Since the cross-sectional shape of the communication channel 9 is continuously deformed from a circular shape to an elliptical shape again while maintaining a cross-sectional area from the upstream side to the downstream side, the chemical liquid flowing through the communication channel 9 Are stirred and mixed inside the communication channel 9.

  In the present embodiment, the branch channel 7 is provided with a portion where the channel cross-sectional area changes. The branch channel 7 has the same channel cross-sectional area as the inlet channel 2 at the branch point 5, but the channel cross-sectional area continuously decreases from the branch point 5 to the junction 6.

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

  The chemical liquid that has flowed into the inlet channel 2 from the fluid inlet 1 flows into the mixing cell 8 and flows into the branch channel 7 via the branch point 5. Since the cross-sectional shape of the branch channel 7 continuously decreases from the branch point 5 to the junction point 6, the flow rate of the chemical solution flowing through the branch channel 7 increases as it approaches the junction point 6. When reaching the junction 6 from the branch flow path 7, the branched chemical solution collides and is mixed, and flows into the communication flow path 9. At this time, since the chemical solution is accelerated in the branch flow path 7, it collides more violently and is efficiently mixed. The chemical solution that has passed through the communication channel 9 flows downstream, passes through all the mixing cells 8 and the communication channel 9, flows into the outlet channel 4, and flows out from the fluid outlet 3 to the outside of the static mixer.

  Since the branch channel 7 communicates at the junction 6 at a position that is eccentric with respect to the central axis of the communication channel 9 or the outlet channel 4, the chemical solution is communicated with the communication channel 9 or the outlet channel 4. A swirling flow is generated along the inner wall. Thereby, while the chemical | medical solution which flows through the communication flow path 9 or the exit flow path 4 is stirred efficiently, the dead space in the communication flow path 9 or the exit flow path 4 can be eliminated, and the retention of a chemical | medical solution can be prevented. Moreover, the pressure loss which arises when the chemical | medical solution which passes the branch flow path 7 joins at the junction 6 can be reduced. In addition, the branch flow paths 7 communicate with each other at the branch point 5 at positions eccentric with respect to the flow path central axis of the inlet flow path 2 or the communication flow path 9. At this time, if the branch channel 9 is formed in the same direction as the flow swirling along the inner wall of the communication channel 9, the chemical solution flows into the branch channel 7 according to the flow generated in the communication channel 9. The pressure loss at the branch point 5 can be reduced. In addition, when the branch flow path 9 is formed in a direction different from the flow swirling along the inner wall of the communication flow path 9, the flow direction of the chemical solution is rapidly changed against the flow generated in the communication flow path 9. Since it flows into the branch flow path 7, a chemical | medical solution can be stirred and can be mixed effectively.

  In this embodiment, the branch flow path 7 merges at the same location and the same angle in the communication flow path 9 or the outlet flow path 4, but from different angles and different directions at different locations for each branch flow path 7. They may join and are not particularly limited.
