本考案は、高温ガス炉用中間熱交換器の構造に係り、特に伝熱管の流体振動を 防止可能とした中間熱交換器に関する。 The present invention relates to a structure of an intermediate heat exchanger for a high temperature gas reactor, and more particularly to an intermediate heat exchanger capable of preventing fluid vibration of a heat transfer tube.
【０００２】[0002]
中間熱交換器は、外部容器と、前記外部容器内に設置された内部容器と、この 内部容器と前記外部容器との間に挿通され、その一端が前記内部容器に連結され た複数本の伝熱管とからなり、高温ガス炉等にて高温加熱された一次ガス（熱媒 ）を前記外部容器内に流下させるとともに、前記伝熱管の他端から前記内部容器 に向けて低温の二次ガス（冷媒）を流下させ、前記伝熱管を介して前記ガスの熱 交換を行うもので、その結果加熱された二次ガスはタービンの駆動等に利用され る。 The intermediate heat exchanger is inserted between an outer container, an inner container installed in the outer container, and the inner container and the outer container, and one end of which is connected to the inner container. A primary gas (heat medium), which is composed of a heat pipe and is heated to a high temperature in a high temperature gas furnace, flows down into the outer container, and a low temperature secondary gas (from the other end of the heat transfer pipe to the inner container) (Refrigerant) is caused to flow down and heat of the gas is exchanged through the heat transfer tube. As a result, the heated secondary gas is used for driving a turbine or the like.
【０００３】 上記従来の中間熱交換器における内部容器と伝熱管との連結部分の構造を図４ に示す。内部容器６は円筒状をなし、しかもこの円筒は二重構造となっている。 そして、内部容器６の側面からは伝熱管８が内部容器６の径方向に沿って放射状 に突出している。また、内部容器６の外周面には断熱材９が配設されているが、 図４に示すように、前記連結部分における断熱材９の厚さはそれ以外の部分と比 較して非常に薄くなっている。更に、断熱材９の表面はカバープレート１０で被 覆されている。FIG. 4 shows the structure of the connecting portion between the internal container and the heat transfer tube in the conventional intermediate heat exchanger. The inner container 6 has a cylindrical shape, and the cylinder has a double structure. The heat transfer pipes 8 radially project from the side surface of the inner container 6 along the radial direction of the inner container 6. Further, the heat insulating material 9 is arranged on the outer peripheral surface of the inner container 6, but as shown in FIG. 4, the thickness of the heat insulating material 9 in the connecting portion is very large compared to the other portions. It is thin. Further, the surface of the heat insulating material 9 is covered with a cover plate 10.
【０００４】[0004]
上記従来の中間熱交換器においては、伝熱管７は内部容器６と断熱材９および その表面を覆うカバープレート１０により支持されている。しかしながら、上記 の通り内部容器６の下端部における断熱材９の厚さが他の部分と比較して非常に 薄くなっているため、内部容器６による伝熱管８の支持範囲（図４中Ａで示す範 囲）は非常に狭く、伝熱管８と内部容器６との連結部分周辺において、伝熱管８ の大部分は無支持のまま内部容器６の径方向外方に露出している。従って、伝熱 管８内における二次ガスの局所的な偏流や、特に伝熱管８の曲管部における乱流 形成に伴い伝熱管８が振動する可能性があった。 In the conventional intermediate heat exchanger, the heat transfer tube 7 is supported by the inner container 6, the heat insulating material 9 and the cover plate 10 covering the surface thereof. However, as described above, the thickness of the heat insulating material 9 at the lower end portion of the inner container 6 is extremely thin as compared with the other portions, so that the support range of the heat transfer tube 8 by the inner container 6 (A in FIG. 4). The range shown is very narrow, and most of the heat transfer tube 8 is exposed to the outside in the radial direction of the inner container 6 without being supported in the vicinity of the connecting portion between the heat transfer tube 8 and the inner container 6. Therefore, there is a possibility that the heat transfer tube 8 vibrates due to the local uneven flow of the secondary gas in the heat transfer tube 8 or the formation of turbulent flow particularly in the curved tube portion of the heat transfer tube 8.

本考案は、上記問題を解決するためになされたもので、外部容器と、外部容器 内に設置された内部容器と、前記内部容器の外周を被覆する断熱材および断熱材 の表面を被覆するカバープレートと、この内部容器と前記外部容器との間に挿通 され、その一端が前記断熱材および前記カバープレートを介して前記内部容器に 連結された複数本の伝熱管とを具備し、前記外部容器内に第一の流体を流下させ るとともに前記伝熱管の他端から前記内部容器に向けて第二の流体を流下させ、 前記伝熱管を介して前記流体の熱交換を行う中間熱交換器において、 The present invention has been made to solve the above problems, and an outer container, an inner container installed in the outer container, a heat insulating material that covers the outer periphery of the inner container, and a cover that covers the surface of the heat insulating material. The outer container includes a plate, and a plurality of heat transfer tubes that are inserted between the inner container and the outer container and have one end connected to the inner container through the heat insulating material and the cover plate. In an intermediate heat exchanger that causes a first fluid to flow down inside and a second fluid to flow down from the other end of the heat transfer tube toward the internal container, and performs heat exchange of the fluid through the heat transfer tube ,
【０００６】 前記伝熱管と前記断熱材および前記カバープレートとの介在部分に前記伝熱管 をその周囲から支持する支持部材が配設され、更に、前記支持部材が前記断熱材 および前記カバープレートにより支持されているものである。A support member that supports the heat transfer tube from its periphery is disposed at an intervening portion between the heat transfer tube and the heat insulating material and the cover plate, and the support member is supported by the heat insulating material and the cover plate. It has been done.
【０００７】[0007]
本考案の中間熱交換器においては、前記伝熱管の一端が前記断熱材および前記 カバープレートを介して前記内部容器に連結され、しかも前記伝熱管と前記断熱 材および前記カバープレートとの介在部分に前記伝熱管をその周囲から支持する 支持部材が配設されている。そのため、前記内部容器と前記伝熱管との連結部分 周辺における前記伝熱管への支持点が増加し、前記伝熱管の安定性が向上する。 その結果、前記二次ガスの局所的な偏流や、特に前記伝熱管の曲管部における乱 流の形成に伴う前記伝熱管の振動が防止される。 In the intermediate heat exchanger of the present invention, one end of the heat transfer tube is connected to the inner container via the heat insulating material and the cover plate, and the heat transfer tube is interposed between the heat insulating material and the cover plate. A support member is provided to support the heat transfer tube from its periphery. Therefore, the number of supporting points for the heat transfer tube around the connecting portion between the inner container and the heat transfer tube is increased, and the stability of the heat transfer tube is improved. As a result, the local uneven flow of the secondary gas and the vibration of the heat transfer tube due to the formation of turbulent flow particularly in the curved tube portion of the heat transfer tube are prevented.
【０００８】[0008]
以下、図面に基づき、本考案の実施例について、更に詳しく説明する。 図１は、本考案の中間熱交換器の構造を示すものである。図１において、符号 １は円筒状をなす外部容器で、その下端には一次ガス（第一の流体）吸入口２が 開口している。一方、外部容器１の上端には二次ガス（第二の流体）排出口３が 開口し、二次ガス排出口３の側方には一次ガス排出口４および二次ガス吸入口５ がそれぞれ形成されている。 Hereinafter, embodiments of the present invention will be described in more detail with reference to the drawings. FIG. 1 shows the structure of the intermediate heat exchanger of the present invention. In FIG. 1, reference numeral 1 is an outer container having a cylindrical shape, and a primary gas (first fluid) inlet 2 is opened at the lower end thereof. On the other hand, a secondary gas (second fluid) outlet 3 is opened at the upper end of the outer container 1, and a primary gas outlet 4 and a secondary gas inlet 5 are provided on the sides of the secondary gas outlet 3, respectively. Has been formed.
【０００９】 外部容器１内にはやはり円筒状をなす内部容器６が外部容器１と同軸に挿通さ れ、その上端は二次ガス排出口３に連結される一方、その下端部は二重構造とさ れている。更に、外部容器１の内周面および内部容器６の外周面との隙間にはそ れぞれ断熱材９が配設され、断熱材９の表面はカバープレート１０により被覆さ れている。A cylindrical inner container 6 is also inserted into the outer container 1 coaxially with the outer container 1, the upper end of which is connected to the secondary gas discharge port 3, while the lower end thereof has a double structure. It is said that. Further, a heat insulating material 9 is provided in each of the gaps between the inner peripheral surface of the outer container 1 and the outer peripheral surface of the inner container 6, and the surface of the heat insulating material 9 is covered with a cover plate 10.
【００１０】 この場合、本実施例の中間熱交換器においては、図２に示すように、内部容器 ６と伝熱管８の連結部位における断熱材９の厚さが内部容器６の他の部分と同様 の厚さ（図２中Ｂで示す範囲）となっている。In this case, in the intermediate heat exchanger of this embodiment, as shown in FIG. 2, the thickness of the heat insulating material 9 at the connecting portion between the inner container 6 and the heat transfer tube 8 is different from that of the other part of the inner container 6. The thickness is the same (range shown by B in FIG. 2).
【００１１】 更に、内部容器６下端部の側面には、伝熱管８が、図２および図３に示すよう に、断熱材９およびカバープレート１０を介して内部容器６の径方向に沿って放 射状に突出している。そして、この伝熱管８は、内部容器６の外周上を螺旋状に 巻回するコイル（図示せず）を形成して内部容器６の上端部に至り、そこで互い にまとめられて二次ガス吸入口５に連結されている。Further, as shown in FIGS. 2 and 3, a heat transfer tube 8 is provided on the side surface of the lower end portion of the inner container 6 along a radial direction of the inner container 6 via a heat insulating material 9 and a cover plate 10. It projects in a radial pattern. The heat transfer tube 8 forms a coil (not shown) spirally wound on the outer circumference of the inner container 6 and reaches the upper end of the inner container 6, where they are gathered together to collect the secondary gas. It is connected to the mouth 5.
【００１２】 ここで、本実施例の中間熱交換器においては、内部容器６の下端部における伝 熱管８と断熱材９およびカバープレート１０との介在部分には、伝熱管８をその 周囲から支持する円筒状の支持部材８ａが配設されている。更に、支持部材８ａ の周囲は断熱材９により包み込まれ、また、支持部材８ａとカバープレート１０ との接合部８ｂは溶接等の方法で固定されている。Here, in the intermediate heat exchanger of the present embodiment, the heat transfer tube 8 is supported from the periphery thereof at the intervening portion between the heat transfer tube 8 and the heat insulating material 9 and the cover plate 10 at the lower end of the inner container 6. A cylindrical support member 8a is provided. Further, the periphery of the support member 8a is wrapped with a heat insulating material 9, and the joint portion 8b between the support member 8a and the cover plate 10 is fixed by welding or the like.
【００１３】 すなわち、本考案の中間熱交換器においては、内部容器６の下端部に位置する 伝熱管８と断熱材９およびカバープレート１０との介在部分において、伝熱管８ が支持部材８ａにより支持され、更に支持部材８ａが断熱材９に幅広く包み込ま れ、かつカバープレート１０により固定される構造となっている。しかも、内部 容器６と伝熱管８の連結部位における断熱材９の厚さが内部容器６の他の部分と 同様の厚さとされているため、内部容器６と伝熱管８との連結部分周辺における 伝熱管８への支持点が増加する。従って、伝熱管８は、支持部材８ａを介して、 断熱材９およびその表面を被覆するカバープレート１０により確実に支持され、 その結果、伝熱管８の安定性が向上する。That is, in the intermediate heat exchanger of the present invention, the heat transfer tube 8 is supported by the support member 8a at the intervening portion of the heat transfer tube 8 located at the lower end of the inner container 6 and the heat insulating material 9 and the cover plate 10. Further, the support member 8a is widely wrapped in the heat insulating material 9 and fixed by the cover plate 10. Moreover, since the thickness of the heat insulating material 9 at the connecting portion between the inner container 6 and the heat transfer tube 8 is the same as that of the other portion of the inner container 6, in the vicinity of the connecting portion between the inner container 6 and the heat transfer tube 8. The number of supporting points for the heat transfer tube 8 increases. Therefore, the heat transfer tube 8 is reliably supported by the heat insulating material 9 and the cover plate 10 covering the surface thereof via the support member 8a, and as a result, the stability of the heat transfer tube 8 is improved.
【００１４】 次に、上記構成を有する中間熱交換器を用いた一次ガスから二次ガスへの熱交 換の過程について以下に述べる。Next, the process of heat exchange from the primary gas to the secondary gas using the intermediate heat exchanger having the above configuration will be described below.
【００１５】 一次ガス吸入口２は高温ガス炉（図示せず）に連結されており、加熱された高 温の一次ガスは一次ガス吸入口２から流入し、伝熱管８の隙間を通過して一次ガ ス排出口４から排出され、循環器（図示せず）を介して入口ノズル１１から再流 入され、外部容器１の内周面に設けられた二重壁７との間に流れて外部容器１の 下部の出口ノズル１２より排出される。また、二次ガス吸入口５からは低温の二 次ガスが流入し、伝熱管８にて熱交換され後内部容器６の下端部に集められ、二 次ガス排出口３から排出される。このように、一次ガスと二次ガスとの間で伝熱 管８を介して熱交換が行われ、一次ガスの温度が低下するとともに二次ガスの温 度が上昇する。その結果高温となった二次ガスは二次ガス排出口３から更に前記 タービン（図示せず）等へと送られる。The primary gas inlet 2 is connected to a high temperature gas furnace (not shown), and the heated high-temperature primary gas flows in from the primary gas inlet 2 and passes through the gap of the heat transfer tube 8. It is discharged from the primary gas discharge port 4, re-flowed from the inlet nozzle 11 via a circulator (not shown), and flows between it and the double wall 7 provided on the inner peripheral surface of the outer container 1. It is discharged from the outlet nozzle 12 at the bottom of the outer container 1. Further, a low-temperature secondary gas flows in from the secondary gas suction port 5, undergoes heat exchange in the heat transfer tube 8, and then is collected in the lower end portion of the inner container 6 and discharged from the secondary gas discharge port 3. In this way, heat is exchanged between the primary gas and the secondary gas via the heat transfer tube 8, and the temperature of the primary gas decreases and the temperature of the secondary gas increases. As a result, the secondary gas having a high temperature is sent from the secondary gas outlet 3 to the turbine (not shown) or the like.
【００１６】 一次ガス排出口４および前記循環器を介して出口ノズル１２から排出された一 次ガスは、再度前記高温ガス炉へと戻され、そこで再度加熱して使用される。ま た、前記駆動源に送られた二次ガスは再度二次ガス吸入口５へと循環される。な お、上記従来例において、一次ガスおよび二次ガスにはいずれもヘリウムが用い られ、一次ガス吸入口２における一次ガスの流速および流入温度はそれぞれ３０ ｍ／秒、９００℃とされている。The primary gas discharged from the outlet nozzle 12 via the primary gas discharge port 4 and the circulator is returned to the high temperature gas furnace again, where it is heated again for use. Further, the secondary gas sent to the drive source is circulated to the secondary gas suction port 5 again. In the above-mentioned conventional example, helium is used for both the primary gas and the secondary gas, and the flow velocity and the inflow temperature of the primary gas at the primary gas inlet 2 are 30 m / sec and 900 ° C., respectively.
【００１７】 この場合、伝熱管８内における二次ガスの局所的な偏流や伝熱管８の曲管部に おける乱流の発生は本考案の中間熱交換器においても避けられるものではない。 しかしながら、上記の通り、本考案の中間熱交換器においては、伝熱管８は、支 持部材８ａを介して断熱材９およびその表面を被覆するカバープレート１０によ り広範囲にわたって確実に支持されているため、伝熱管８の振動が防止される。 また、僅かに発生した振動も断熱材９に吸収されて減衰する。In this case, the local non-uniform flow of the secondary gas in the heat transfer tube 8 and the occurrence of turbulent flow in the curved tube portion of the heat transfer tube 8 cannot be avoided even in the intermediate heat exchanger of the present invention. However, as described above, in the intermediate heat exchanger of the present invention, the heat transfer tube 8 is reliably supported over a wide area by the heat insulating material 9 and the cover plate 10 covering the surface thereof through the supporting member 8a. Therefore, the vibration of the heat transfer tube 8 is prevented. Further, the vibration generated slightly is absorbed by the heat insulating material 9 and attenuated.
【００１８】 一方、における断熱材９の幅Ｂを厚くすることによりカバープレート１０が内 部容器６の径方向外方へと移動するため、支持部材８ａとカバープレート１０と の取付け作業が容易になるという効果もある。On the other hand, since the cover plate 10 moves radially outward of the inner container 6 by increasing the width B of the heat insulating material 9, the work of attaching the support member 8a and the cover plate 10 is facilitated. There is also the effect of becoming.
【００１９】 なお、上記実施例の中間熱交換器においては、伝熱管８と支持部材８ａとを別 部材とし、支持部材８ａにより伝熱管８を周囲から支持する構成としたが、伝熱 管８と支持部材８ａとを一体に成形し、この伝熱管８と支持部材との一体成形物 を断熱材９およびカバープレート１０により支持する構成としてもよい。また、 上記実施例の中間熱交換器においては、特に伝熱管８の曲管部における振動を防 止する目的で、支持部材８ａを延長し、この延長部分が伝熱管８の曲管部を覆う 構成としたが、この延長部分は不要な場合には特に設けずともよい。更に、本考 案の中間熱交換器における前記連結部位の構造を、内部断熱構造を有するシェル アンドチューブ型の熱交換器に応用することも可能である。In the intermediate heat exchanger of the above embodiment, the heat transfer tube 8 and the support member 8a are separate members, and the support member 8a supports the heat transfer tube 8 from the surroundings. And the support member 8a may be integrally formed, and the integrally formed product of the heat transfer tube 8 and the support member may be supported by the heat insulating material 9 and the cover plate 10. Further, in the intermediate heat exchanger of the above-described embodiment, the support member 8a is extended for the purpose of particularly preventing vibration in the curved tube portion of the heat transfer tube 8, and this extended portion covers the curved tube portion of the heat transfer tube 8. Although it is configured, this extension may not be provided if it is unnecessary. Furthermore, the structure of the connecting portion in the intermediate heat exchanger of the present invention can be applied to a shell-and-tube heat exchanger having an internal heat insulating structure.
【００２０】[0020]
以上説明したように、本考案の中間熱交換器においては、伝熱管の一端が断熱 材およびカバープレートを介して内部容器に連結され、しかも前記伝熱管と前記 断熱材および前記カバープレートとの介在部分に前記伝熱管をその周囲から支持 する支持部材が配設される。その結果、前記内部容器と前記伝熱管との連結部分 周辺における前記伝熱管への支持点が増加し、前記伝熱管の安定性が向上するた め、二次ガスの局所的な偏流や前記伝熱管の曲管部における乱流の形成に伴う前 記伝熱管の振動が防止され、前記中間熱交換器の健全性が向上する。 As described above, in the intermediate heat exchanger of the present invention, one end of the heat transfer tube is connected to the inner container via the heat insulating material and the cover plate, and the heat transfer tube and the heat insulating material and the cover plate are interposed.
