The temperature of the second fluid L2 supplied to the merging portion 14 is substantially constant. The supply amount of the second fluid L <b> 2 supplied to the merge unit 14 is adjusted by the supply amount adjusting device 43. The supply amount of the first fluid L1 supplied to the junction 14 is not adjusted. The supply amount of the first fluid L1 supplied to the merge portion 14 is substantially constant.

  Since the first fluid L1 is cooled and the second fluid L2 is not cooled, the temperature of the first fluid L1 supplied to the junction 14 is different from the temperature of the second fluid L2. In the present embodiment, the supply amount of the second fluid L2 supplied to the merging portion 14 is adjusted by the supply amount adjusting device 43, and the mixing ratio of the first fluid L1 and the second fluid L2 in the merging portion 14 is adjusted.

The distance C is 7.3D. The distance E is 1.6D. The diameter D is 550 mm.

  Next, operation | movement of the mixing apparatus 1 which concerns on this embodiment is demonstrated. A part of the fluid L0 supplied from the fluid supply source to the first pipe portion 11 is branched at the branching portion 17 and supplied to the second pipe 20. The temperature of the first fluid L <b> 1 in the first pipe portion 11 is adjusted (cooled) by the cooler device 42. The supply amount of the second fluid L <b> 2 of the second pipe 20 is adjusted by the supply amount adjusting device 43. The supply amount of the second fluid L2 is adjusted based on the detection result of the temperature sensor 41.

  The 1st fluid L1 of the 1st pipe part 11 and the 2nd fluid L2 of the 2nd piping 20 merge in the junction part 14, and are mixed. Thereby, the mixed fluid LM is generated. The mixed fluid LM in the merging portion 14 flows in the flow path of the second pipe portion 12 after flowing in the flow path of the bent portion 13.

  A part of the mixed liquid LM flowing through the flow path of the bent portion 13 flows into the internal space 30 </ b> S of the protruding member 30. The mixed fluid LM that has flowed into the internal space 30 </ b> S hits the inner peripheral surface 33 and the closing surface 34. When the mixed fluid LM hits the blocking surface 34, the mixing of the mixed fluid LM is promoted. The mixed fluid LM sufficiently mixed in the internal space 30 </ b> S flows out (returns) to the flow path of the bent portion 13 through the first opening 31.

  The mixed fluid LM that has returned from the internal space 30 </ b> S to the flow path of the bent portion 13 is mixed with the mixed fluid LM of the flow path of the bent portion 13 at the connection portion 15. The flow direction of the mixed fluid LM flowing from the first pipe portion 11 through the bent portion 13 to the second pipe portion 12 is different from the flow direction of the mixed fluid LM returning from the internal space 30S to the flow path of the bent portion 13. . Therefore, in the connection part 15, mixing with the mixed fluid LM which flows into the 2nd pipe part 12 through the bending part 13 from the 1st pipe part 11, and the mixed fluid LM which returns to the flow path of the bending part 13 from internal space 30S is mixed. Promoted.

  Thus, since the protruding member 30 is provided, mixing of the mixed fluid LM is promoted. Thereby, in the case where the mixed fluid LM is generated by mixing the first fluid L1 and the second fluid L2 having different temperatures, the temperature of the generated mixed fluid LM is suppressed from becoming uneven.

  The sufficiently mixed fluid LM flows through the flow path of the second pipe portion 12 and then flows out from the outlet 16. As shown in FIGS. 1 and 2, the outlet 16 of the second pipe portion 12 is connected to an inlet 203 of a piping system 200 having a first branch channel 201 and a second branch channel 202. The mixed fluid LM that has flowed out from the outlet 16 of the second pipe portion 12 is supplied to each of the first branch channel 201 and the second branch channel 202 via the inlet 203.

  The mixed fluid LM that has flowed through the first branch flow path 201 is supplied to the first device 101. The mixed fluid LM that has flowed through the second branch flow path 202 is supplied to the second device 102. The temperature of the first device 101 is adjusted (cooled) by the mixed fluid LM supplied via the first branch channel 201. The temperature of the second device 102 is adjusted (cooled) by the mixed fluid LM supplied via the second branch flow path 202.

  In the present embodiment, the temperature of the first device 101 and the second device 102 is adjusted with the mixed fluid LM having a uniform temperature. Therefore, poor temperature control (cooling failure) of the first device 101 and the second device 102 is suppressed.

  As described above, according to the present embodiment, since the projecting member 30 is provided, when the mixed fluid LM is generated by mixing the first fluid L1 and the second fluid L2, the generated mixed fluid LM The temperature can be made uniform. Therefore, the temperature of the equipment of the plant 100 can be sufficiently adjusted using the mixed fluid LM.

  Moreover, the mixing of the mixed fluid LM can be promoted only by providing the protruding member 30, and an increase in the size of the mixing device 1 can be suppressed.

  Further, in the present embodiment, the protruding member 30 is disposed so that the central axis AX11 of the first pipe portion 11 and the central axis AX33 of the inner peripheral surface 33 coincide with each other. Thereby, the mixed fluid LM from the 1st pipe part 11 (merging part 14) can flow smoothly into internal space 30S.

  In the present embodiment, the closing surface 34 is disposed so as to be orthogonal to the central axis AX11 (central axis AX33). As a result, the mixed fluid LM is sufficiently agitated by hitting the closing surface 34 to promote mixing.

  In the present embodiment, the central axis AX11 of the first pipe part 11 and the central axis AX12 of the second pipe part 12 are orthogonal to each other. Thereby, mixing with the mixed fluid LM which returned to the flow path of the bending part 13 from the internal space 30S, and the mixed fluid LM which flows into the 2nd pipe part 12 through the bending part 13 from the 1st pipe part 11 is promoted more. The

  Moreover, in this embodiment, the outflow port 16 of the 2nd pipe part 12 is connected with the inflow port 203 of the piping system 200 which has a some branch flow path (201,202). Thereby, the mixed fluid LM is efficiently supplied to the plurality of devices via the plurality of branch channels, and the temperature adjustment of the plurality of devices can be performed efficiently and smoothly.

  Further, in the present embodiment, the temperature sensor 41 disposed in the second pipe part 12, the cooler device 42 disposed in the first pipe part 11, the second pipe 20, and the first pipe part 11. A supply amount adjusting device 43 capable of adjusting the supply amount of the second fluid L2 to be supplied is provided. Based on the detection result of the temperature sensor 41, the supply amount of the second fluid L2 is adjusted by the supply amount adjusting device 43, whereby the temperature of the mixed fluid LM can be adjusted to the target temperature. Therefore, the occurrence of poor temperature control of the device is suppressed.

  Further, the first end 21 of the second pipe 20 is connected to the first pipe part 11, and the second fluid L <b> 2 is supplied from the first pipe part 11. Accordingly, the mixed fluid LM having the desired temperature can be generated using the fluid L0 from one fluid supply source without providing a plurality of fluid supply sources.

  In the present embodiment, each of the first fluid L1 and the second fluid L2 is a liquid. Therefore, compared with gas, an apparatus can be efficiently and fully cooled.

  In the present embodiment, the temperature of the first fluid L1 supplied to the merging portion 14 and the second fluid L2 supplied from the second end 22 of the second pipe 20 to the merging portion 14 of the first pipe portion 11. Unlike the temperature, the protruding member 30 makes the temperature distribution of the mixed fluid LM uniform. The composition of the first fluid L1 supplied to the junction 14 may be different from the composition of the second fluid L2 supplied to the junction 14. When the first fluid L1 and the second fluid L2 having different compositions are mixed to generate the mixed fluid LM, the protruding member 30 makes the composition of the mixed fluid LM uniform. Further, even when the first fluid L1 and the second fluid L2 are solutions and the concentrations thereof are different, the concentration of the mixed fluid LM is made uniform by the protruding member 30. Further, even when the first fluid L1 and the second fluid L2 having different chemical reactivity are mixed to generate the mixed fluid LM, the chemical reactivity of the mixed fluid LM is made uniform. Thus, even if the properties of the first fluid L1 and the properties of the second fluid L2 are different, the properties of the mixed fluid LM are made uniform by the protruding member 30.

  In the present embodiment, the mixed fluid LM is generated by mixing two kinds of fluids (L1, L2). Three or more kinds of fluids may be mixed to generate the mixed fluid LM. The same applies to the following embodiments.

  In the present embodiment, the piping system 200 has two branch channels, but of course, it may have three or more branch channels.
