流量をＱとすると、体積Ｑ−ｔＨの高温水と体積Ｑ−ｔ
ｔ、の低温水を完全に混合すれば、均一な温度Ｔｍ′Ｃ
が得られるが、第１図及び第２図に示す従来の攪拌装置
では、全体積Ｑ−ｔＨ＋Ｑ−ｔＬの数倍の容積を必要と
する。If the flow rate is Q, then the volume Q-tH of high-temperature water and the volume Q-t
If low-temperature water of t is thoroughly mixed, the temperature becomes uniform Tm'C
However, the conventional stirring apparatus shown in FIGS. 1 and 2 requires a volume several times the total volume Q-tH+Q-tL.
その上、攪拌機構を定量的に表現できないので、攪拌装
置の大きさや最適構造を決定するために、実験に頼らざ
るを得ないのが現状である。Furthermore, since the stirring mechanism cannot be expressed quantitatively, it is currently necessary to rely on experiments to determine the size and optimal structure of the stirring device.
従って、攪拌容器が大きくなるため、製作コストも高く
なっている。Therefore, since the stirring container becomes larger, the manufacturing cost also becomes higher.
本発明の目的は上記の点に着目し、小型で製作コストが
低減できると共に効率の良い混合装置を提供することで
あり、その特徴とするところは、配管を２本に分岐し、
その１本を長くして時間遅れを生じさせ、再び合流させ
て混合するようにしたことである。The purpose of the present invention is to focus on the above-mentioned points, and to provide a compact and efficient mixing device that can reduce production costs and is characterized by branching the piping into two,
One of the lines was lengthened to create a time delay, and then they were brought together again for mixing.
本発明は核融合炉、化学プラント等の混合装置に広く適
用できる。The present invention can be widely applied to mixing devices such as nuclear fusion reactors and chemical plants.
以下図面を参照して本発明による実施例につき説明する
。Embodiments of the present invention will be described below with reference to the drawings.
第３図は本発明による１実施例の装置を示す説明図であ

図において、１は入口管、２はショートパス管、即ち短
絡路、３はバイパス管、即ち側路、４はオリフィスまた
は弁、５は出口管である。In the figure, 1 is an inlet pipe, 2 is a short path pipe, 3 is a bypass pipe, 4 is an orifice or valve, and 5 is an outlet pipe.
入口管１を通って入って来た流量Ｑの流体は分岐点Ａで
ショートパス管２とバイパス管３に分れる。A fluid having a flow rate Q entering through the inlet pipe 1 is divided into a short path pipe 2 and a bypass pipe 3 at a branch point A.
ショートパス管２とバイパス管３の断面積をそれぞれＳ
ｌ、Ｓ２とし、長さをそれぞれＬｌ、Ｌ２とする。The cross-sectional areas of the short path pipe 2 and the bypass pipe 3 are respectively S
1 and S2, and their lengths are Ll and L2, respectively.
ショートパス管２の流量をＱ、とすると、通過に要する
時間はｔ、＝Ｓｔ Ｌ１／Ｑｔである。When the flow rate of the short path pipe 2 is Q, the time required for passage is t, =St L1/Qt.
方バイパス管３の流量をＱ２とすると、通過に要する時
間はｔ２＝ Ｓ２ Ｌ２／Ｑ２となり、一般にｔ１央ｔ
２ とすることができる。If the flow rate of bypass pipe 3 is Q2, the time required for passage is t2 = S2 L2/Q2, and generally t1 middle t

この時、流量分配Ｑ１：Ｑ２はショートパス管２とバイ
パス管３の管路損失によって決まるので、オリフィスま
たは弁４により任意に調節できる。At this time, the flow rate distribution Q1:Q2 is determined by the line loss of the short path pipe 2 and the bypass pipe 3, so it can be adjusted as desired by the orifice or valve 4.
従って、ショートパス管２とバイパス管３を通った流体
はＢ点で合流する時に時間差Ａｔ−ｔ２−ｔｌをもつ。Therefore, when the fluids passing through the short path pipe 2 and the bypass pipe 3 meet at point B, there is a time difference At-t2-tl.
この時、温度の異なる部分が合流するように、寸法Ｌ１
゜Ｌ２．Ｓｌ、Ｓ２ とオリフィスまたは弁４の抵抗を
調節することにより出口管５の中で混合が起る。At this time, the dimension L1 is
゜L2. By adjusting the resistance of Sl, S2 and the orifice or valve 4, mixing takes place in the outlet pipe 5.
上記構成の場合の作用、効果について述べる。The functions and effects of the above configuration will be described.
予め高温流体の流入時間ｔＨと低温流体の流入時間ｔＬ
が明らかであるとすると、この状態の流入流体の温度変
化を時間ｔに対して表わすと第４図ａのようになる。The inflow time tH of high temperature fluid and the inflow time tL of low temperature fluid are determined in advance.
Assuming that is clear, the temperature change of the inflowing fluid in this state is expressed as a function of time t as shown in FIG. 4a.
簡単のため、５＝８１＝８２、＝Ｑ１＝Ｑ２ としり場

Ｌｌが次式を満足するように決めると、出口管５の流体
の温度は第４図すのようになる。For simplicity, 5=81=82, =Q1=Q2 In this case, if the lengths L2 and Ll of the bypass pipe 3 and the short lotus pipe 2 are determined to satisfy the following formula, the fluid in the outlet pipe 5 The temperature is as shown in Figure 4.
なお、ｔｒｌｌｌ−ｔＬ＋ｔＨ／２であり、また第４図
すにおいて一点鎖線ａはバイパス管３より出口側合流点
Ｂで合流する流体の温度変化を、破線すはショートパス
管２より合流する流体の温度変化を、実線Ｃは混合後の
流体の温度変化を示す。In addition, in Fig. 4, the dashed line a represents the temperature change of the fluid that joins from the bypass pipe 3 at the outlet side junction B, and the broken line represents the temperature change of the fluid that joins from the short path pipe 2. The solid line C shows the temperature change of the fluid after mixing.
即ち、この場合は、前記した時間差Ｊｔ ＝ ｔ２ｔＬ
＋ｔＨ
ｔｌ””ｔｍ１＝□とすることにより、図示のように、
ｔＩ、＋ｔＨの時間帯で２回ｔＨ時間だけ混合すること
ができる。That is, in this case, the above-mentioned time difference Jt = t2tL
By setting +tH tl””tm1=□, as shown in the figure,
Mixing can be performed twice for tH time in the tI and +tH time periods.
もし、ｔｌ、＝ｔＨであるなら、この段階で完全混合が
なされる。If tl,=tH, complete mixing is achieved at this stage.
この時に必要な混合装置の容積Ｖは、Ｌ１中。The volume V of the mixing device required at this time is L1.
と近似して、
となり、混合すべき液体の全体積Ｑ（ｔＬ＋ｔＨ）の１
／４で済む。Approximately, it becomes 1 of the total volume Q (tL + tH) of the liquid to be mixed.
/4 is enough.
しかも、量産品の管で作れるので、製作コストを大巾に
下げることができる。Moreover, since it can be made from mass-produced pipes, production costs can be significantly reduced.
ｔ Ｌ ４ ｔ Ｈの場合、本発明の混合装置をもう１
段付けることにより、温度変化を第４図Ｃのようにでき
る。In the case of t L 4 t H, one more mixing device of the present invention is used.
By providing steps, temperature changes can be made as shown in FIG. 4C.
ただし、管の断面積５＝８１＝８２と流量Ｑ／２＝Ｑｔ
＝Ｑ２という条件をここでも設定し、バイパス管３の長
さＬ１２ とショートパス管２の長さＬ／１が次式を満
足するように製作する。However, the cross-sectional area of the pipe 5 = 81 = 82 and the flow rate Q/2 = Qt
=Q2 is set here as well, and the length L12 of the bypass pipe 3 and the length L/1 of the short path pipe 2 are manufactured so as to satisfy the following formula.
と非常に小さい。And very small.
第４図Ｃ程度の温度変化は管路中で平坦にされる可能性
も充分であるが、必要ならば本発明の混合装置をさらに
増やすか、小さなタンクを下流に取付けてもよい。Although there is a good possibility that a temperature change of the order of FIG. 4C will be flattened out in the pipe line, if necessary, the number of mixing devices of the present invention may be further increased or a small tank may be installed downstream.
また、配管は曲げることができるので、設置条件を考え
ても、従来の容量、即ちＱ（ｔＬ＋ｔＨ）の数倍、に比
べはるかに小型にできる上、確実な混合ができるので、
設計時に実験を行わなくても定量的な検討ができる。In addition, since the piping can be bent, even considering the installation conditions, it can be made much smaller than the conventional capacity, which is several times Q (tL + tH), and it also allows for reliable mixing.
Quantitative studies can be performed without conducting experiments during design.
上述のように本発明による場合は、小型で安価な混合装
