本発明は、流体加熱装置に関するものである。 The present invention relates to a fluid heating apparatus.
流体加熱装置としては、特許文献１に示すように、中空導体管を通電加熱して、当該導体管の内部を流れる流体を加熱して加熱流体を発生するものがある。この流体加熱装置では、導体管の両端部に設けた電極から交流電圧が印加されて、導体管の側壁に交流電流が流れることにより、導体管の内部抵抗により発生するジュール熱によって導体管が自己発熱する。この導体管の自己発熱によって、当該導体管を流れる流体が加熱される。 As a fluid heating device, as shown in Patent Document 1, there is a device that energizes and heats a hollow conductor tube and heats a fluid flowing inside the conductor tube to generate a heated fluid. In this fluid heating apparatus, an AC voltage is applied from the electrodes provided at both ends of the conductor tube, and an AC current flows through the side wall of the conductor tube, so that the conductor tube self-acts due to Joule heat generated by the internal resistance of the conductor tube. Fever. The fluid flowing through the conductor tube is heated by the self-heating of the conductor tube.
しかしながら、導体管の両端部に交流電圧を印加するものでは、導体管が有するインダクタンスによって電圧降下が生じ、当該導体管に交流電圧を印加する回路の力率が低下するという問題がある。 However, when the AC voltage is applied to both ends of the conductor tube, there is a problem that a voltage drop occurs due to the inductance of the conductor tube, and the power factor of the circuit that applies the AC voltage to the conductor tube is reduced.
そこで本発明は、上記問題点を一挙に解決するためになされたものであり、内部に流体が流れる流路形成体を通電加熱する流体加熱装置において、回路力率を改善して設備効率を向上させることをその主たる所期課題とするものである。 Accordingly, the present invention has been made to solve the above-mentioned problems all at once, and in a fluid heating apparatus that energizes and heats a flow path forming body through which a fluid flows, the circuit power factor is improved and the equipment efficiency is improved. The main intended task is to make it happen.
すなわち本発明に係る流体加熱装置は、内部に被加熱流体が流れる導電性材料からなる流路形成体を通電加熱して、前記流路を流れる被加熱流体を加熱する流体加熱装置であって、前記流路形成体が、直線状の流路を形成する１又は複数の直線部を有し、前記直線部に、前記流路を流れる流体を噴出する複数の流体噴出口が設けられ、前記直線部における前記流路の流路方向に沿って複数の電極が接続されており、互いに隣り合う前記電極に接続される単相交流電源の極性が異なるように、単相交流電源のＵ相及びＶ相が交互に接続されていることを特徴とする。 That is, the fluid heating device according to the present invention is a fluid heating device that heats the heated fluid flowing through the flow path by energizing and heating the flow path forming body made of a conductive material through which the heated fluid flows. The flow path forming body has one or a plurality of straight line portions that form a straight flow path, and the straight line portion is provided with a plurality of fluid jets that eject the fluid that flows through the flow path. A plurality of electrodes are connected along the flow path direction of the flow path in the section, and the U-phase and V of the single-phase AC power supply are different so that the polarities of the single-phase AC power supplies connected to the electrodes adjacent to each other are different. The phases are connected alternately.
このようなものであれば、互いに隣り合う前記電極間に流れる電流の位相が互いに逆向きとなるので、それぞれの電流により発生する磁束が打ち消し合い、前記流路形成体に発生するインピーダンスが低減されて回路力率を改善することができる。したがって、流体加熱装置の設備効率を向上させることができる。また、前記直線部に複数の流体噴出口が設けられているので、加熱された被加熱流体を流路形成体から外部の所定の噴射範囲に直接噴出することができる。 In such a case, the phases of the currents flowing between the electrodes adjacent to each other are opposite to each other, so that the magnetic fluxes generated by the respective currents cancel each other, and the impedance generated in the flow path forming body is reduced. The circuit power factor can be improved. Therefore, the equipment efficiency of the fluid heating device can be improved. In addition, since the plurality of fluid ejection ports are provided in the straight portion, the heated fluid to be heated can be directly ejected from the flow path forming body to a predetermined external ejection range.
前記直線部を前記流路方向に沿って２ｎ等分（ｎは１以上の整数である。）する位置に、前記電極がそれぞれ接続されていることが望ましい。これならば、各電極間に発生する磁束量が略等しくなり、前記電極間に発生する磁束を効率良く打ち消すことができる。 It is desirable that the electrodes are respectively connected to the position where the straight portion is equally divided into 2n along the flow path direction (n is an integer of 1 or more). In this case, the amount of magnetic flux generated between the electrodes becomes substantially equal, and the magnetic flux generated between the electrodes can be canceled out efficiently.
また本発明に係る流体加熱装置は、内部に被加熱流体が流れる流路が形成された導電性材料からなる流路形成体を通電加熱して、前記流路を流れる被加熱流体を加熱する流体加熱装置であって、前記流路形成体が、それぞれ互いに略平行に配置され、直線状の流路を形成する２ｎ個（ｎは１以上の整数である。）の直線部と、互いに隣り合う前記直線部の端部を接続して蛇行した１本の流路を形成する２ｎ−１個の折返し部とを有し、前記流路形成体に前記流路を流れる流体を噴出する複数の流体噴出口が設けられ、前記流路形成体において、前記蛇行した流路の両端部に電極が接続されるとともに、前記２ｎ−１個の折返し部の少なくとも１つに電極が接続されており、前記複数の電極が、前記流路方向に沿って互いに隣り合う電極の間の流路を形成する前記直線部が偶数個になるように接続されており、前記流路方向に沿って互いに隣り合う電極に接続される単相交流電源の極性が異なるように、単相交流電源のＵ相及びＶ相が交互に接続されていることが望ましい。 Moreover, the fluid heating apparatus according to the present invention is a fluid for heating the fluid to be heated flowing through the flow path by energizing and heating a flow path forming body made of a conductive material in which the flow path through which the fluid to be heated flows is formed.

It is desirable that the U phase and the V phase are connected alternately.
このようなものであれば、互いに隣り合う前記直線部に流れる電流が互いに逆向きとなるので、それぞれの電流により発生する磁束が打ち消し合い、流路形成体に発生するインピーダンスが低減されて回路力率を改善することができる。したがって、流体加熱装置の設備効率を向上させることができる。また、前記直線部に複数の流体噴出口が設けられているので、加熱された被加熱流体を流路形成体から外部の所定の噴射範囲に直接噴出することができる。 In such a case, since the currents flowing in the linear portions adjacent to each other are opposite to each other, the magnetic fluxes generated by the respective currents cancel each other, and the impedance generated in the flow path forming body is reduced to reduce the circuit force. The rate can be improved. Therefore, the equipment efficiency of the fluid heating device can be improved. In addition, since the plurality of fluid ejection ports are provided in the straight portion, the heated fluid to be heated can be directly ejected from the flow path forming body to a predetermined external ejection range.

Therefore, the equipment efficiency of the fluid heating device can be improved. Moreover, since the several fluid jet nozzle is provided in the said linear part, it can eject to the predetermined injection range defined.

Thereby, the flow path R becomes a linear flow path. The flow path forming body 2 is made of a conductive material having a higher electrical resistance than copper, and may be formed of, for example, stainless steel or titanium. In addition, the flange part 21 is formed in the 1st distribution port P1 which is one end opening by the side of the flow-path end part 2a of the flow-path formation body 2, and it is comprised so that a connection with external piping is possible.

ここで、流体加熱装置１００における被加熱流体の流れを説明する。被加熱流体は、流路Ｒに連通する流路形成体２の第１流通口Ｐ１から流入し、流路形成体２内部の流路Ｒを加熱されながら流れ、流路Ｒに連通する流路形成体２の第２流通口Ｐ２に至る。加熱された流体の一部は、この第１流通口Ｐ１から第２流通口Ｐ２に至るまでの間に、流体噴出口２２及び流体噴出ノズル２４を通って流体加熱装置１００の外部に噴出される。また、第１流通口Ｐ１又は第２流通口Ｐ２の一方を閉塞し、第１流通口Ｐ１又は第２流通口Ｐ２の他方から被加熱流体を流入させる構成にして、加熱された流体の全部を流体噴出口２２及び流体噴出ノズル２４から外部に噴出させるようにしても良い。さらに、第１流通口Ｐ１及び第２流通口Ｐ２の両方から被加熱流体を流入させる構成にして、加熱された流体の全部を流体噴出口２２及び流体噴出ノズル２４から外部に噴出させるようにしても良い。なお、被加熱流体の一例としては、流路形成体２に流入する被加熱流体が、飽和水蒸気又は過熱水蒸気であって、流路形成体２から流出する加熱された流体が過熱水蒸気であることが考えられる。ただし、被加熱流体は、特定の流体に限られることはなく、流体加熱装置１００の用途に合わせて適宜選択されるものであれば良い。 Here, the flow of the fluid to be heated in the fluid heating apparatus 100 will be described. The heated fluid flows from the first flow port P1 of the flow path forming body 2 communicating with the flow path R, flows while being heated in the flow path R inside the flow path forming body 2, and communicates with the flow path R. It reaches the second flow port P2 of the formed body 2. Part of the heated fluid is ejected to the outside of the fluid heating device 100 through the fluid ejection port 22 and the fluid ejection nozzle 24 during the period from the first circulation port P1 to the second circulation port P2. . Further, one of the first circulation port P1 and the second circulation port P2 is closed, and the heated fluid is introduced from the other of the first circulation port P1 or the second circulation port P2, and all of the heated fluid is supplied. You may make it eject from the fluid ejection port 22 and the fluid ejection nozzle 24 outside. Further, the heated fluid is introduced from both the first circulation port P1 and the second circulation port P2, and all of the heated fluid is ejected from the fluid ejection port 22 and the fluid ejection nozzle 24 to the outside. Also good. As an example of the fluid to be heated, the fluid to be heated that flows into the flow path forming body 2 is saturated steam or superheated steam, and the heated fluid that flows out from the flow path forming body 2 is superheated steam. Can be considered. However, the fluid to be heated is not limited to a specific fluid, and any fluid may be selected as appropriate according to the application of the fluid heating apparatus 100.
このように構成した流体加熱装置１００において、単相交流電源から単相交流電圧を各電極３を介して流路形成体２に印加すると、互いに隣り合う電極３間に流れる電流の位相が互いに逆向きとなるので、それぞれの電流により発生する磁束が打ち消し合い、流路形成体２に発生するインピーダンスが低減されて回路力率を改善することができる。したがって、被加熱流体を効率良く加熱することができ、流体加熱装置１００の設備効率を向上させることができる。 In the fluid heating apparatus 100 configured as described above, when a single-phase AC voltage is applied from the single-phase AC power source to the flow path forming body 2 via the electrodes 3, the phases of the currents flowing between the adjacent electrodes 3 are opposite to each other. Therefore, the magnetic fluxes generated by the respective currents cancel each other out, the impedance generated in the flow path forming body 2 is reduced, and the circuit power factor can be improved. Therefore, the fluid to be heated can be efficiently heated, and the equipment efficiency of the fluid heating apparatus 100 can be improved.
なお、本実施形態の流体加熱装置１００は、流路形成体２が１つの直線部２５のみにより形成される構成に限られず、直線部２５を複数有するものであっても良い。具体的には、図２に示すように、外側周面に複数の流体噴出口２２が設けられた直線部２５を例えば３つ有するものであっても良い。具体的に３つの直線部２５は、流路他端部２ｂ側において導電性を有する接続部２６により接続されており、直線部２５及び接続部２６により流路形成体２が構成されている。つまり、この流体加熱装置１００の配管構成は、流路一端部２ａ側に３つの第１流通口Ｐ１を有し、流路他端部２ｂ側に１つの第２流通口Ｐ２を有する。この接続部２６は、被加熱流体が流路一端部２ａから流路他端部２ｂに向かって流れる場合には３つの流路を１つの流路に合流させ、被加熱流体が流路他端部２ｂから流路一端部２ａに向かって流れる場合には１つの流路を３つの流路に分流させるものである。 In addition, the fluid heating apparatus 100 of this embodiment is not restricted to the structure in which the flow-path formation body 2 is formed only by the one linear part 25, You may have multiple linear parts 25. FIG. Specifically, as shown in FIG. 2, for example, three linear portions 25 having a plurality of fluid ejection ports 22 provided on the outer peripheral surface may be provided. Specifically, the three straight portions 25 are connected by a connecting portion 26 having conductivity on the flow channel other end portion 2 b side, and the flow path forming body 2 is configured by the straight portion 25 and the connecting portion 26. In other words, the piping configuration of the fluid heating device 100 has three first circulation ports P1 on the flow channel one end 2a side and one second circulation port P2 on the flow channel other end 2b side. When the fluid to be heated flows from one end 2a of the flow channel toward the other end 2b of the flow channel, the connection portion 26 joins the three flow channels into one flow channel, and the fluid to be heated is connected to the other end of the flow channel. In the case of flowing from the portion 2b toward the flow path one end 2a, one flow path is divided into three flow paths.
このように直線部２５を複数有する場合であっても、流路形成体２における流路一端部２ａから流路他端部２ｂの間を流路Ｒの流路方向に沿って２ｎ等分する位置に電極３が配置されていることが望ましい。例えば図２の流体加熱装置１００の場合、各直線部２５は同一平面上において略平行に配置されている。また、電極３は直線部２５の配列方向に沿って（図２における下方から）見たときに、流路Ｒの流路方向に沿って略４等分する位置に接続されている。さらに、直線部２５に接続された複数の電極３は、隣り合う直線部２５に接続された電極３と流路Ｒの流路方向に沿ってそれぞれ略同じ位置に接続されている。なお、直線部２５は３つに限られず、２つでも良いし、４つ以上であっても良い。また、各直線部２５が、例えば放射状に配置されている等、略平行に配置されていないものであっても良い。 Thus, even when there are a plurality of straight portions 25, the distance between the flow path one end 2a and the flow path other end 2b in the flow path forming body 2 is equally divided into 2n along the flow path direction of the flow path R. It is desirable that the electrode 3 is disposed at the position. For example, in the case of the fluid heating apparatus 100 of FIG. 2, each linear part 25 is arrange | positioned substantially parallel on the same plane. Further, the electrode 3 is connected to a position that is divided into approximately four equal parts along the flow path direction of the flow path R when viewed along the arrangement direction of the linear portions 25 (from the lower side in FIG. 2). Furthermore, the plurality of electrodes 3 connected to the straight line portion 25 are connected to substantially the same position along the flow path direction of the flow path R and the electrode 3 connected to the adjacent straight line portion 25. Note that the number of straight portions 25 is not limited to three, and may be two, or four or more. Moreover, each linear part 25 may be what is not arrange | positioned substantially parallel, for example, is arrange | positioned radially.

Since the directions are opposite, the magnetic fluxes generated by the respective currents cancel each other out, the impedance generated in the flow path forming body 2 is reduced, and the circuit power factor can be improved. Therefore, the fluid to be heated can be efficiently heated, and the equipment efficiency of the fluid heating apparatus 100 can be improved.

このように構成した流体加熱装置１００において、三相交流電源５から三相交流電圧を各電極３を介して流路形成体２に印加すると、連続して並ぶ３つの直線部２５の間に流れる電流の位相がそれぞれ互いに１２０°異なるので、それぞれの電流により発生する磁束が打ち消し合い、流路形成体２に発生するインピーダンスが低減されて回路力率を改善することができる。したがって、被加熱流体を効率良く加熱することができ、流体加熱装置１００の設備効率を向上させることができる。 In the fluid heating apparatus 100 configured as described above, when a three-phase AC voltage is applied from the three-phase AC power source 5 to the flow path forming body 2 via each electrode 3, the fluid flows between the three linear portions 25 that are continuously arranged. Since the phases of the currents are different from each other by 120 °, the magnetic fluxes generated by the respective currents cancel each other, the impedance generated in the flow path forming body 2 is reduced, and the circuit power factor can be improved. Therefore, the fluid to be heated can be efficiently heated, and the equipment efficiency of the fluid heating apparatus 100 can be improved.
