That is, the linear flow path 11 may have a linear first central axis O1, and the thickness may vary in the longitudinal direction. The thickness of the linear channel 11 may be, for example, 1 cm or less. Also, the cross-sectional area of the linear flow path 11 may be, for example, 1 cm 2 or less.

FIG.
　フローリアクタ５は、直線状の第１中心軸線Ｏ１を中心とする第１流路１４（直線状流路１１を含む）と、直線状の第２中心軸線Ｏ２を中心とする第２流路１５と、を有する。連通口１１ａは第１流路１４と第２流路１５の境界に位置し、連通口１１ａの中心Ｃは第２中心軸線Ｏ２に一致する。 The flow reactor 5 includes a first flow path 14 (including a linear flow path 11) centered on a first linear central axis O1 and a second flow path 15 centered on a second linear central axis O2. and have The communication port 11a is located at the boundary between the first flow path 14 and the second flow path 15, and the center C of the communication port 11a coincides with the second central axis O2.
　温度センサ３は、取り付けねじ４を取り付け筒部１０に取り付けることによって、取り付け口１０ａに取り付けられ、直線状流路１１内を長手方向側に連通口１１ａを超えて延びる。また、温度センサ３は、図示のように、長手方向に平行に設置されることが好ましい。ただし、温度センサ３は長手方向に平行に設置されるものに限定されず、長手方向に対してある程度の傾斜をもって設置されてもよい。例えば、温度センサ３は直線状流路１１内の流体の流れに影響しない程度の傾斜角度、温度センサ３が変形等することなく正常に機能することができる傾斜角度、又は、長手方向に対して０°以上４５°未満の傾斜角度を有して設置されてもよい。なお、本明細書における長手方向側とは、長手方向に対して０°以上４５°未満の傾斜角度を有する方向を意味する。このような構成によれば、反応流路を流れる流体に流路継手２の内部流路の太さを超える長さで温度センサ３を接触させることができるので、温度の検出精度を高め易くすることができる。 The temperature sensor 3 is attached to the attachment port 10a by attaching the attachment screw 4 to the attachment cylinder portion 10, and extends in the linear flow path 11 in the longitudinal direction beyond the communication port 11a. Also, the temperature sensor 3 is preferably installed parallel to the longitudinal direction as shown. However, the temperature sensor 3 is not limited to being installed parallel to the longitudinal direction, and may be installed with a certain degree of inclination with respect to the longitudinal direction. For example, the temperature sensor 3 has an inclination angle that does not affect the flow of the fluid in the linear flow path 11, an inclination angle that allows the temperature sensor 3 to function normally without deformation, or an inclination angle that allows the temperature sensor 3 to function normally. It may be installed with an inclination angle of 0° or more and less than 45°. In this specification, the term "longitudinal side" means a direction having an inclination angle of 0° or more and less than 45° with respect to the longitudinal direction. According to such a configuration, the temperature sensor 3 can be brought into contact with the fluid flowing in the reaction channel over a length exceeding the thickness of the internal channel of the channel joint 2, thereby facilitating an increase in temperature detection accuracy. be able to.
　取り付けねじ４は取り付け筒部１０の内周面に螺合可能である。つまり、取り付けねじ４を、取り付け口１０ａを形成する内周面に螺合することで、取り付けねじ４を取り付け口１０ａに取り付けることができる。なお、取り付けねじ４はこれに限らず、例えば、取り付け筒部１０の外周面に螺合可能に構成してもよい。 The mounting screw 4 can be screwed into the inner peripheral surface of the mounting cylinder portion 10 . That is, the mounting screw 4 can be attached to the mounting opening 10a by screwing the mounting screw 4 into the inner peripheral surface forming the mounting opening 10a. In addition, the mounting screw 4 is not limited to this, and may be configured so as to be screwed onto the outer peripheral surface of the mounting tube portion 10, for example.
　温度センサ３は、取り付けねじ４の内部に固定される固定部３ａと、固定部３ａから直線状流路１１内に延び、流体に接触する延設部３ｂと、を有する。本実施形態では固定部３ａは延設部３ｂよりも太い。このような構成によれば、取り付け口１０ａへの取り付けねじ４の取り付けに伴って生じる応力による温度センサ３の損傷を抑制し易く、しかも温度センサ３による温度の検出感度を高め易くすることができる。またこのような構成は、上記のように取り付けねじ４が取り付け筒部１０の内周面に螺合可能な構成である場合に特に有効である。 The temperature sensor 3 has a fixed portion 3a fixed inside the mounting screw 4, and an extended portion 3b extending from the fixed portion 3a into the linear flow path 11 and in contact with the fluid. In this embodiment, the fixed portion 3a is thicker than the extension portion 3b. According to such a configuration, damage to the temperature sensor 3 due to stress caused by attaching the mounting screw 4 to the mounting port 10a can be easily suppressed, and the temperature detection sensitivity of the temperature sensor 3 can be easily increased. . Moreover, such a configuration is particularly effective when the mounting screw 4 can be screwed into the inner peripheral surface of the mounting cylinder portion 10 as described above.
　取り付け筒部１０は第１中心軸線Ｏ１を中心とする筒状をなす。また温度センサ３は直線状をなし、固定部３ａにおいて取り付けねじ４の中心に固定される。したがって、温度センサ３は第１中心軸線Ｏ１と同軸に延びる。 The mounting tubular portion 10 has a tubular shape centered on the first central axis O1. The temperature sensor 3 has a linear shape and is fixed to the center of the mounting screw 4 at the fixing portion 3a. Therefore, the temperature sensor 3 extends coaxially with the first central axis O1.
　連通口１１ａの中心Ｃから取り付け口１０ａ（中心Ｃ側の端部）までの直線状流路１１の長手方向の長さＬ１（以下、第１長さＬ１ともいう）は例えば、図示するように、連通口１１ａの中心Ｃから第１接続口８ａ（中心Ｃ側の端部）までの直線状流路１１の長手方向の長さＬ２（以下、第２長さＬ２ともいう）よりも短い。このような構成によれば、連通口１１ａよりも取り付け口１０ａの側に形成される流路のデッドボリュームを減少させることができるので、デッドボリュームでの流体の滞留による閉塞や流れの不安定化を抑制し易くすることができる。例えば、固・液混相流の場合、滞留は固体の析出、詰まりによる閉塞や流れの不安定化を招く虞があり、気・液混相流の場合、気体が捕捉されることで閉塞や流れの不安定化を招く虞がある。 The longitudinal length L1 (hereinafter also referred to as the first length L1) of the linear flow path 11 from the center C of the communication port 11a to the attachment port 10a (the end on the center C side) is, for example, as shown in the figure. , the longitudinal length L2 of the linear flow path 11 from the center C of the communication port 11a to the first connection port 8a (the end on the center C side) (hereinafter also referred to as the second length L2). With such a configuration, it is possible to reduce the dead volume of the flow path formed closer to the attachment port 10a than the communication port 11a. can be made easier to suppress. For example, in the case of a solid-liquid mixed phase flow, stagnation may lead to clogging or destabilization of the flow due to deposition of solids or clogging. This may lead to instability.
　なお、流路継手２、取り付けねじ４、第１流路部材１２及び第２流路部材１３の材質は樹脂製や金属製であってもよく、例えばフッ素樹脂、ＰＥＥＫ（Poly Ether Ether Ketone）やステンレス鋼などからそれぞれ適宜選択されうる。また、温度センサ３の表面材質と取り付けねじ４の材質はそろっていることが好ましい。 The material of the flow path joint 2, the mounting screw 4, the first flow path member 12 and the second flow path member 13 may be resin or metal. They can be appropriately selected from stainless steel and the like. Moreover, it is preferable that the surface material of the temperature sensor 3 and the material of the mounting screw 4 are the same.
　流路の有効断面積（流体が通過する部分の断面積）は流れ方向にできるだけ一定であることが好ましい。流路の有効断面積を流れ方向に略一定とすることにより、滞留時間を制御することができる。このため、第１流路１４は、温度センサ３の延設部３ｂの横断面積を考慮し、第１流路１４の有効断面積が長手方向にできるだけ一定となるように設計することが好ましい。つまり、直線状流路１１の横断面積から温度センサ３の延設部３ｂの横断面積を減算した値が流路部材１２の中空部分の横断面積とほぼ同一となるように、流路継手２と温度センサ３とを設計することが好ましい。このとき、温度センサ３の延設部３ｂが直線状流路１１内に収容されるように、直線状流路１１は、取り付け口１０ａの一端（中心Ｃ側の端部）であって温度センサの延設部３ｂの基端部（固定部３ａ側の端部）近傍から、第１流路部材１２又は第１接続口８ａの一端（中心Ｃ側の端部）であって温度センサ３の延設部３ｂの先端部（固定部３ａと反対側の端部）近傍まで延びる流路と定義される。 It is preferable that the effective cross-sectional area of the flow path (the cross-sectional area of the portion through which the fluid passes) is as constant as possible in the flow direction. The retention time can be controlled by making the effective cross-sectional area of the channel substantially constant in the direction of flow. Therefore, it is preferable to design the first flow path 14 in consideration of the cross-sectional area of the extension portion 3b of the temperature sensor 3 so that the effective cross-sectional area of the first flow path 14 is as constant as possible in the longitudinal direction. That is, the flow path joint 2 is arranged so that the cross-sectional area of the extension portion 3b of the temperature sensor 3 subtracted from the cross-sectional area of the linear flow path 11 is substantially the same as the cross-sectional area of the hollow portion of the flow path member 12. The temperature sensor 3 is preferably designed. At this time, the linear flow path 11 is one end (the end on the center C side) of the mounting port 10a and the temperature sensor so that the extended portion 3b of the temperature sensor 3 is accommodated in the linear flow path 11. From the vicinity of the base end portion (the end portion on the fixed portion 3a side) of the extension portion 3b, the first flow path member 12 or one end (the end portion on the center C side) of the first connection port 8a (the end portion on the center C side) of the temperature sensor 3 It is defined as a channel extending to the vicinity of the tip of the extending portion 3b (the end opposite to the fixed portion 3a).
　また流体の化学反応を安定化させるためには、第１流路部材１２及び第２流路部材１３内で流れる流体への外部からの熱的影響と流路継手２内で流れる流体への外部からの熱的影響とができるだけ等しいことが好ましい。このため、流路継手２は、熱抵抗が第１流路部材１２及び第２流路部材１３とできるだけ等しくなるように材質と肉厚を設定することが好ましい。したがって、第１流路部材１２及び第２流路部材１３が管状である場合、流路継手２は、図示するように、第１接続口８ａと取り付け口１０ａとが対向配置されるＴ字型の３方分岐継手として構成するのが好ましい。 Further, in order to stabilize the chemical reaction of the fluid, it is necessary to prevent the fluid flowing in the first flow path member 12 and the second flow path member 13 from being affected by heat from the outside and the fluid flowing in the flow path joint 2 from the outside. It is preferable that the thermal effects from For this reason, it is preferable to set the material and thickness of the flow joint 2 so that the thermal resistance is as equal as possible to the first flow channel member 12 and the second flow channel member 13 . Therefore, when the first flow path member 12 and the second flow path member 13 are tubular, the flow path joint 2 has a T-shaped configuration in which the first connection port 8a and the attachment port 10a are arranged to face each other, as shown in the figure. is preferably configured as a 3-way branch joint.
　温度センサ３は固定部３ａが延設部３ｂよりも太い構成に限らず、例えば、図２に示す第２実施形態のように、固定部３ａが延設部３ｂと等しい太さである構成としてもよい。また、取り付けねじ４と固定部３ａとの間に筒部材１６を介装する構成としてもよい。筒部材１６の材質は温度センサ３の表面材質、取り付けねじ４とそろえてあることが好ましい。 The temperature sensor 3 is not limited to a configuration in which the fixed portion 3a is thicker than the extended portion 3b. For example, as in the second embodiment shown in FIG. good too. Further, a configuration in which a cylindrical member 16 is interposed between the mounting screw 4 and the fixing portion 3a may be adopted. The material of the tubular member 16 is preferably the same as the surface material of the temperature sensor 3 and the mounting screw 4 .
