本考案は、熱交換器に係り、特に、熱交換器シェルと流体集合筒との間に配さ れる螺旋形状の伝熱管の熱交換流体による振動を防止する技術に関するものであ る。 The present invention relates to a heat exchanger, and more particularly to a technique for preventing vibration of a spiral heat transfer tube arranged between a heat exchanger shell and a fluid collecting cylinder due to a heat exchange fluid.

原子炉の一種に、ヘリウムを熱媒体として使用する高温ガス炉がある。この高 温ガス炉に使用される熱交換器には、図７に示すように、立設状態に配される円 筒状の熱交換器シェル１の内部に直立状態の内筒（流体集合筒）２を配すること によって、該内筒２と熱交換器シェル１との間に円筒状の熱交換流路３が形成さ れている。該熱交換流路３には、螺旋状の伝熱管４が内筒２の周囲を取り巻いて 配置され、該伝熱管４の下端は、内筒２の下部に集合状態に接続されている。ま た、伝熱管４の上端は、熱交換器シェル１上部のガス入口ヘッダ５に接続されて いる。 One type of nuclear reactor is a high temperature gas reactor that uses helium as a heat medium. As shown in FIG. 7, a heat exchanger used in this high-temperature gas furnace has an inner cylinder (fluid collecting cylinder) in an upright state inside a cylindrical heat exchanger shell 1 arranged in an upright state. 2) is arranged, a cylindrical heat exchange passage 3 is formed between the inner cylinder 2 and the heat exchanger shell 1. In the heat exchange passage 3, a spiral heat transfer tube 4 is arranged around the inner cylinder 2, and the lower end of the heat transfer tube 4 is connected to the lower part of the inner cylinder 2 in a collective state. Moreover, the upper end of the heat transfer tube 4 is connected to the gas inlet header 5 above the heat exchanger shell 1.
【０００３】 前記熱交換流路３には、熱交換器シェル１の下部に配設された高温流体入口６ から高温状態の一次側ヘリウムが上方に向かって挿通させられ、熱交換器シェル １の上部に設けられた高温流体出口７から外部に排出されるようになっている。 また、前記伝熱管４には、熱交換器Ｙ上部のガス入口ヘッダ５から流入させた二 次側ヘリウムが下方に向かって螺旋状に挿通させられた後に、内筒２の下部で集 合させられて、該内筒２内部を上方に通って熱交換器Ｙ上部のガス出口８から排 出されるようになっている。そして、これらの一次側・二次側ヘリウムの挿通の 間、つまり、熱交換流路３に挿通させられる一次側ヘリウムと該熱交換流路３に 配される伝熱管４の内部を挿通させられる二次側ヘリウムとの間に熱交換が行わ れるようになっている。The primary side helium in a high temperature state is inserted upward into the heat exchange passage 3 from a high temperature fluid inlet 6 arranged in the lower part of the heat exchanger shell 1, and The high temperature fluid outlet 7 provided at the upper portion is discharged to the outside. Further, the secondary side helium introduced from the gas inlet header 5 above the heat exchanger Y is inserted into the heat transfer tube 4 spirally downward, and then assembled at the lower part of the inner cylinder 2. Then, the gas passes through the inside of the inner cylinder 2 upward and is discharged from the gas outlet 8 in the upper part of the heat exchanger Y. Then, during the insertion of these primary-side / secondary-side helium, that is, inside of the primary-side helium inserted into the heat exchange passage 3 and the inside of the heat transfer tube 4 arranged in the heat exchange passage 3 are inserted. Heat is exchanged with the secondary helium.
【０００４】 ところで、伝熱管４の内外には、上述のように流体が流通させられるので、該 伝熱管４が流体によって振動させられないように支持する必要がある。また、伝 熱管４は常温において組み付けられ、稼働時に高温状態とされるので、発生する 熱変形を拘束しないように支持する必要がある。このような伝熱管４の支持方法 としては、従来、図８に示すように、前記熱交換流路３の長手方向に沿って配さ れる平板状の管束支持板９を内筒２の周方向に間隔をおいて複数設けるとともに 、該管束支持板９を内筒２に固定する支持梁１０および内筒２を支持する内筒支 持梁１１を配設することが行われる。By the way, since the fluid is circulated inside and outside the heat transfer tube 4 as described above, it is necessary to support the heat transfer tube 4 so as not to be vibrated by the fluid. Further, since the heat transfer tube 4 is assembled at room temperature and brought into a high temperature state during operation, it is necessary to support it so as not to restrain the thermal deformation that occurs. As a conventional method of supporting the heat transfer tubes 4, as shown in FIG. 8, a flat plate-shaped tube bundle support plate 9 arranged along the longitudinal direction of the heat exchange passage 3 is arranged in the circumferential direction of the inner cylinder 2. A plurality of them are provided at intervals, and a support beam 10 for fixing the tube bundle support plate 9 to the inner cylinder 2 and an inner cylinder supporting beam 11 for supporting the inner cylinder 2 are arranged.
【０００５】 管束支持板９は、図８に示すように、熱交換流路３に沿う梯子状の部材であっ て、熱交換流路３の半径方向に間隔をおいて複数並列に配されている。そして、 該管束支持板９のピッチに合わせて配される伝熱管４を周回ごとに梯子の格子間 に挿通させることにより、伝熱管４の熱変形を許容しつつ支持することができる ようになっている。As shown in FIG. 8, the tube bundle support plate 9 is a ladder-shaped member along the heat exchange flow passage 3, and is arranged in parallel at a plurality of intervals in the radial direction of the heat exchange flow passage 3. There is. Then, by inserting the heat transfer tubes 4 arranged in accordance with the pitch of the tube bundle support plate 9 between the grids of the ladder for each revolution, it is possible to support the heat transfer tubes 4 while allowing thermal deformation of the heat transfer tubes 4. ing.
【０００６】 前記支持梁１０は、例えば、内筒２の外面に周方向に間隔をおいて放射状に固 設された梁状部材であって、前記管束支持板９の上端部を取り付けることにより 、伝熱管４を吊持するようになっている。また、前記内筒支持梁１１も、伝熱管 ４の下方位置において内筒２の外面に周方向に間隔をおいて放射状に固設された 梁状部材である。これら支持梁１０および内筒支持梁１１の先端部は、それぞれ 熱交換器シェル１の内面に近接状態に配置され、かつ、熱交換器シェル１の内面 に突出状態に形成された支持突起１２によって周方向に微小隙間を空けて挟持さ れることにより、内筒２の長手方向への自由な変位と半径方向への若干の変位を 許容するようになっている。The support beam 10 is, for example, a beam-shaped member radially fixed to the outer surface of the inner cylinder 2 at intervals in the circumferential direction, and by attaching the upper end portion of the tube bundle support plate 9, The heat transfer tube 4 is suspended. The inner cylinder support beam 11 is also a beam-like member that is radially fixed to the outer surface of the inner cylinder 2 at a position below the heat transfer tube 4 at intervals in the circumferential direction. The tips of the support beam 10 and the inner cylinder support beam 11 are respectively arranged in the vicinity of the inner surface of the heat exchanger shell 1 and by the support projections 12 formed on the inner surface of the heat exchanger shell 1 in a protruding state. By being sandwiched with a minute gap in the circumferential direction, free displacement of the inner cylinder 2 in the longitudinal direction and slight displacement in the radial direction are allowed.
【０００７】 したがって、内筒２に熱変形が生じた場合には、長手方向および半径方向への 変位が許容され、内筒２に水平方向の振動が発生した場合には、支持梁１０およ び内筒支持梁１１を支持突起１２または熱交換器シェル１の内面に当接させるこ とにより、該振動を抑制することができる。さらに、これら支持梁１０および内 筒支持梁１１によって、内筒２を介して管束支持板９の水平方向の振動が抑制さ れることになる。Therefore, when the inner cylinder 2 is thermally deformed, displacement in the longitudinal direction and the radial direction is allowed, and when horizontal vibration is generated in the inner cylinder 2, the support beams 10 and The vibration can be suppressed by bringing the inner cylinder support beam 11 into contact with the support projection 12 or the inner surface of the heat exchanger shell 1. Further, the support beam 10 and the inner cylinder support beam 11 suppress the horizontal vibration of the tube bundle support plate 9 through the inner cylinder 2.
【０００８】[0008]
しかしながら、このような熱交換器Ｙであると、内筒２を支持する内筒支持梁 １１が、伝熱管４の下方、すなわち、熱交換流路３の上流側に配置されているた めに、熱交換流路３に流入する一次側ヘリウムの流れが該内筒支持部材１１によ って乱され、伝熱管４に対する流れの均一化が図れない。このため、熱交換性能 の低下が発生するという不都合が考えられる。また、管束支持板９は、主に、そ の上端部に配される支持梁１０により支持されているために、伝熱管４に発生す る振動を抑制することが困難である。 However, in such a heat exchanger Y, the inner cylinder support beam 11 that supports the inner cylinder 2 is arranged below the heat transfer tube 4, that is, on the upstream side of the heat exchange passage 3. The flow of the primary side helium flowing into the heat exchange passage 3 is disturbed by the inner cylinder support member 11, and the flow to the heat transfer tube 4 cannot be made uniform. Therefore, there is a possibility that the heat exchange performance is deteriorated. Further, since the tube bundle support plate 9 is mainly supported by the support beam 10 arranged at the upper end portion thereof, it is difficult to suppress the vibration generated in the heat transfer tube 4.
【０００９】 本考案は、上述した事情に鑑みてなされたものであって、伝熱管４の振動を確 実に抑制し、かつ、熱交換性能の向上、組立容易性の向上等を図ることができる 熱交換器を提供することを目的としている。The present invention has been made in view of the above-mentioned circumstances, and it is possible to reliably suppress vibration of the heat transfer tube 4, improve heat exchange performance, and improve assembly ease. It is intended to provide a heat exchanger.

【００１７】 そして、この熱交換器Ｙを組み立てるには、まず、内筒２の突条部２５と同数 の管束支持板２０を各伝熱管４に取り付けておく。そして、径寸法の最も小さい 伝熱管４の半径方向内方に内筒２を挿入する。この挿入の際には、内筒２の突条 部２５と最小径の伝熱管４の管束支持板２０の位相が一致するように配し、各管 束支持板２０の直線溝２２に内筒２の突条部２５が挿入されるようにする。これ により、内筒２の突条部２５は、管束支持板２０の直線溝２２によって案内され て、容易に挿入されることになる。そして、内筒２に固設された支持梁１０に固 定することによって伝熱管４が内筒２に固定されることになる。この場合にあっ て、管束支持板２０の直線溝２２と内筒２の突条部２５とは、半径方向に若干の 隙間を有するように填め合わされており、熱交換器Ｙの稼働による温度上昇に伴 う内筒２、伝熱管４の径方向への熱変形を許容するようになっている。To assemble this heat exchanger Y, first, the same number of tube bundle support plates 20 as the protrusions 25 of the inner cylinder 2 are attached to each heat transfer tube 4. Then, the inner cylinder 2 is inserted radially inward of the heat transfer tube 4 having the smallest diameter. At the time of this insertion, the protrusions 25 of the inner cylinder 2 and the tube bundle support plates 20 of the heat transfer tubes 4 having the smallest diameter are arranged so that the phases thereof match, and the inner cylinders are fitted in the straight grooves 22 of each tube bundle support plate 20. The two ridges 25 are inserted. As a result, the ridge portion 25 of the inner cylinder 2 is guided by the straight groove 22 of the tube bundle support plate 20 and is easily inserted. Then, the heat transfer tube 4 is fixed to the inner cylinder 2 by being fixed to the support beam 10 fixed to the inner cylinder 2. In this case, the linear groove 22 of the tube bundle support plate 20 and the protruding portion 25 of the inner cylinder 2 are fitted so as to have a slight radial gap, and the temperature rise due to the operation of the heat exchanger Y. Due to this, the inner cylinder 2 and the heat transfer tube 4 are allowed to undergo thermal deformation in the radial direction.
【００１８】 次いで、次に小さい径寸法の伝熱管４を前記最小径の伝熱管４の半径方向外方 に外嵌させる。この際においても、両伝熱管４の管束支持板２０を合わせて挿入 することにより、相互の間隔が一定に保持された状態で挿入作業が容易に実施さ れる。さらに、同様にして他の伝熱管４を順次挿入する場合にも、該伝熱管４に 取り付けられた管束支持板２０の直線溝２２を、その前に挿入された伝熱管４の 管束支持板２０の突条２１に填め合わせた状態で実施することにより、その挿入 が案内されて、所定位置に容易に組み付けられることになる。この場合において も、管束支持板２０の突条２１と直線溝２２とが、径方向に若干移動可能となる 伝熱管４相互の間隔寸法に設定されており、温度変化に伴う伝熱管４の熱変形を 許容することができるようになっている。Next, the heat transfer tube 4 having the next smaller diameter is fitted on the outer side in the radial direction of the heat transfer tube 4 having the smallest diameter. Also in this case, by inserting the tube bundle support plates 20 of both heat transfer tubes 4 together, the insertion work can be easily performed with the mutual spacing kept constant. Further, when the other heat transfer tubes 4 are sequentially inserted in the same manner, the straight groove 22 of the tube bundle support plate 20 attached to the heat transfer tube 4 is inserted into the tube bundle support plate 20 of the heat transfer tube 4 inserted before. By carrying out the fitting with the ridges 21, the insertion is guided and the assembly can be easily performed at a predetermined position. In this case as well, the projections 21 and the linear grooves 22 of the tube bundle support plate 20 are set to have an interval dimension between the heat transfer tubes 4 that allows a slight radial movement, and the heat of the heat transfer tubes 4 due to temperature changes. Deformation is allowed.
【００１９】 そして、このようにして内筒２の周囲に半径方向に間隔をおいて、例えば、６ 条の伝熱管４が取り付けられたものを熱交換器シェル１に挿入することにより熱 交換器Ｙが形成されることになる。この挿入の際においても、前記内筒２に取り 付けられた伝熱管４のうち、最大径の伝熱管４に取り付けられている管束支持板 ２０の突条２１を、熱交換器シェル１の内面に形成された直線溝２２に填め合わ せた状態で挿入することにより、該直線溝２２によって挿入作業が案内され、熱 交換器シェル１に対して伝熱管４を位置決め状態に組み付けることが可能となる 。In this way, the heat exchanger shell 1 is inserted into the heat exchanger shell 1 at intervals in the radial direction around the inner cylinder 2, for example, with the six heat transfer tubes 4 attached thereto. Y will be formed. Even at the time of this insertion, the protrusion 21 of the tube bundle support plate 20 attached to the heat transfer tube 4 having the largest diameter among the heat transfer tubes 4 attached to the inner cylinder 2 is attached to the inner surface of the heat exchanger shell 1. The insertion work is guided by the straight groove 22 formed in the heat exchanger shell 1 by fitting the heat transfer tube 4 to the heat exchanger shell 1 in a positioned state. Become .
【００２０】 このようにして構成された熱交換器Ｙにおいては、内筒２と最小径の伝熱管４ とが内筒２の外面に設けられた突条部２５と管束支持板２０の直線溝２２とを填 め合わせた状態とされているので、突条部２５の側面と、直線溝２２の溝壁とが 当接させられることによって最小径の伝熱管４と内筒２とが周方向にその相対変 位を拘束される。また、伝熱管４相互においても、隣接する管束支持板２０の突 条２１と直線溝２２とを填め合わせた状態とされており、周方向への相対変位が 相互に拘束される。さらに、最大径の伝熱管４と熱交換器シェル１との間におい ても、伝熱管４の管束支持板２０と熱交換器シェル１の直線溝２２とが填め合わ されることにより、同様にして、周方向への相対変位が拘束される。In the heat exchanger Y thus configured, the inner cylinder 2 and the heat transfer tube 4 having the smallest diameter are provided on the outer surface of the inner cylinder 2 and the linear groove of the tube bundle support plate 20. Since the side wall of the ridge 25 and the groove wall of the straight groove 22 are brought into contact with each other, the heat transfer tube 4 having the smallest diameter and the inner cylinder 2 are circumferentially arranged. Is bound by the relative transformation. Further, the heat transfer tubes 4 are also in a state in which the protrusions 21 and the linear grooves 22 of the adjacent tube bundle support plates 20 are fitted to each other, and the relative displacement in the circumferential direction is mutually restricted. Further, even between the heat transfer tube 4 having the largest diameter and the heat exchanger shell 1, the tube bundle support plate 20 of the heat transfer tube 4 and the straight groove 22 of the heat exchanger shell 1 are fitted to each other, so that the same is achieved. Thus, the relative displacement in the circumferential direction is restricted.
【００２１】 その結果、内筒２は、伝熱管４の管束支持板２０を介して熱交換器シェル１に 対し、その周方向への相対変位を拘束されることになり、従来採用されていた内 筒支持梁が不要となって、伝熱管４の上流側に配される障害物を排除することが できることになる。As a result, the inner cylinder 2 is restrained from its relative displacement in the circumferential direction with respect to the heat exchanger shell 1 via the tube bundle supporting plate 20 of the heat transfer tube 4, which has been conventionally adopted. Since the inner cylinder support beam is not necessary, the obstacle arranged on the upstream side of the heat transfer tube 4 can be eliminated.
【００２２】 このように構成された熱交換器Ｙを稼働させた場合には、熱交換器シェル１と 内筒２との間に形成された円筒状の熱交換流路３に下から上に向けて一次側ヘリ ウムが流通させられ、かつ、伝熱管４内に二次側ヘリウムが流通させられる。 この場合にあって、一次側ヘリウムは、熱交換器シェル１下部の高温流体入口 ６から熱交換流路３内に配される伝熱管４の周囲に挿通させられることになるが 、本実施例の熱交換器Ｙでは、伝熱管４の下方に、内筒支持梁等の障害物が配さ れていないため、伝熱管４の周囲に流入する際の流れの状態が乱されることなく 均一化を図ることが可能となる。そして、その結果、所望の熱伝達性能を得るこ とができる。When the heat exchanger Y having the above-described structure is operated, the cylindrical heat exchange passage 3 formed between the heat exchanger shell 1 and the inner cylinder 2 is moved from bottom to top. The primary-side helium is circulated toward it, and the secondary-side helium is circulated in the heat transfer tube 4. In this case, the primary side helium is inserted from the high temperature fluid inlet 6 at the bottom of the heat exchanger shell 1 into the periphery of the heat transfer tube 4 arranged in the heat exchange passage 3. In the heat exchanger Y of No, since the obstacles such as the inner cylinder supporting beam are not arranged below the heat transfer tube 4, the flow state when flowing into the periphery of the heat transfer tube 4 is not disturbed and is uniform. Can be realized. As a result, a desired heat transfer performance can be obtained.
【００２３】 また、伝熱管４の内外に流通させられる一次側・二次側ヘリウムによって、伝 熱管４に流体関連振動、特に、伝熱管４の周方向への振動が発生するが、伝熱管 ４は管束支持板２０を介して内筒２および熱交換器シェル１によってその周方向 への相対変位を拘束されているので、その振動が抑制されることになる。この場 合にあって、各伝熱管４は、管束支持板２０の突条２１と直線溝２２とを填め合 わせ、突条２１の側面と直線溝２２の溝壁とを当接状態としているので、振動抑 制力は、熱交換流路３の長手方向全長に亙る広い面積で受けられることにより分 散され、主として支持梁１０のみで振動抑制力を受ける従来の構造のように局部 的に過大な応力を生ずることがなく、熱交換器Ｙの健全性を保持することができ る。Further, fluid-related vibrations, particularly vibrations in the circumferential direction of the heat transfer tube 4, are generated in the heat transfer tube 4 by the primary-side / secondary-side helium that is circulated in and out of the heat transfer tube 4. Since its relative displacement in the circumferential direction is restricted by the inner cylinder 2 and the heat exchanger shell 1 via the tube bundle support plate 20, its vibration is suppressed. In this case, in each heat transfer tube 4, the projection 21 of the tube bundle support plate 20 and the linear groove 22 are fitted together, and the side surface of the projection 21 and the groove wall of the linear groove 22 are in contact with each other. Therefore, the vibration suppressing force is dispersed by being received in a large area over the entire length in the longitudinal direction of the heat exchange flow path 3, and is locally localized like the conventional structure in which the vibration suppressing force is mainly received only by the support beam 10. The soundness of the heat exchanger Y can be maintained without causing excessive stress.

Six heat transfer tubes 4 are provided, but instead, the heat transfer tubes 4 having an arbitrary number of threads may be provided.

Although the groove is used, an arbitrary inner support member locking means and outer support member locking means should be adopted instead. The outer support member locking means 24 is a linear groove formed by the two strip members 23, but instead, a linear groove is formed directly on the inner wall surface of the heat exchanger shell 1.
