この考案は、エチレンプラントなどで使用されるプレートフィン型気液二相流 熱交換器の改良に係り、通路に直交する方向に溝付きバーを挿入配置して通路強 度を低下させない構成とし、溝付きバーには鉛直面に設けた水平方向溝と、鉛直 方向の複数の貫通孔あるいは複数の鉛直方向溝とが溝付きバー内の連通孔にて連 通させて、通路外より水平方向溝に流入する気相又は液相流体と通路内の鉛直方 向の気相又は液相流体とを均質に混合可能にしたプレートフィン型気液二相流熱 交換器に関する。 This invention relates to an improvement of a plate fin type gas-liquid two-phase flow heat exchanger used in an ethylene plant, etc., in which a grooved bar is inserted and arranged in a direction orthogonal to the passage so as not to reduce the passage strength. In the grooved bar, a horizontal groove provided on the vertical surface and a plurality of vertical through holes or a plurality of vertical grooves are made to communicate with each other through a communication hole in the grooved bar. The present invention relates to a plate fin type gas-liquid two-phase flow heat exchanger capable of homogeneously mixing a gas phase or liquid phase fluid flowing into a pipe and a gas phase or liquid phase fluid in the vertical direction in a passage.

エチレンプラント、空気分離プラントなどで使用されるプレートフィン型気液 二相流熱交換器は、予め気液分離装置で気体と液体に分離させておいた気液二相 流体を熱交換のため、熱交換器の一方の通路に流入させる際に、別々の入口から 流入させて通路内で混合させ、他方通路の流体と熱交換させる構成からなる。 従って、通路内での気液の混合率が場所によって異なると、安定した熱交換を 得ることができず、生産効率の低下や、さらには過熱あるいは過冷により熱交換 器を損傷することがある。 Plate fin type gas-liquid two-phase flow heat exchangers used in ethylene plants, air separation plants, etc. are used for heat exchange of gas-liquid two-phase fluid that has been separated into gas and liquid by a gas-liquid separator in advance. When flowing into one passage of the heat exchanger, it is made to flow from different inlets, mixed in the passage, and exchange heat with the fluid in the other passage. Therefore, if the mixing ratio of gas and liquid in the passage differs depending on the location, stable heat exchange cannot be obtained, which may reduce production efficiency or even damage the heat exchanger due to overheating or overcooling. .
【０００３】 そこで、均質な気液二相流体を得るために、従来のプレートフィン型熱交換器 では、図６に示す如く、上下方向に気相が流れる当該通路の伝熱フィン３ｃを分 断し、気相流れに直交する方向にインジェクションチューブ５０を挿入し、イン ジェクションチューブ５０に設けられた多数の孔より液相を流入させて、気液の 混合を行う構成が採用されており、さらに、通路のフィン形状を工夫するなど、 均質な混合が行われるように構成していた。Therefore, in order to obtain a homogeneous gas-liquid two-phase fluid, in the conventional plate fin type heat exchanger, as shown in FIG. 6, the heat transfer fins 3c in the passage in which the gas phase flows vertically are divided. Then, the injection tube 50 is inserted in a direction orthogonal to the gas phase flow, and the liquid phase is introduced from a large number of holes provided in the injection tube 50 to mix the gas and liquid. Furthermore, the fin shape of the passage was devised so that uniform mixing was performed.
【０００４】 また、特開昭５８−８６３９６号に示されるように、図６に示すインジェクシ ョンチューブに代えて、水平方向のバー部材を配置してバー部材の出口にて気相 と液相を混合する構成が提案されている。Further, as shown in Japanese Patent Laid-Open No. 58-86396, instead of the injection tube shown in FIG. 6, a horizontal bar member is arranged and a gas phase and a liquid phase are mixed at the outlet of the bar member. A configuration to do so has been proposed.
【０００５】[0005]
しかし、図６に示す従来の構成は、気相の流れに直接液相を注入するので混合 性にはすぐれているが、強度主体である通路のフィンを分断して挿入配置される ため、同部に高い圧力をかけることができないという問題があった。 また、インジェクションチューブ１本で処理できる量には限界があり、多量の 液相を処理する場合には図６に示すように、複数本の当該チューブを必要とし、 強度低下と共に製作工程が増える問題があった。 一方、バー部材を用いる場合は、上記の強度上の問題は解消されるが、通路の 広がったバー部材の出口にて気相と液相を混合するために、混合性に劣る問題が あった。 However, the conventional structure shown in FIG. 6 has excellent mixing properties because the liquid phase is directly injected into the gas phase flow, but since the fins of the passage, which is mainly the strength, are divided and inserted, the same structure is used. There was a problem that high pressure could not be applied to the part. In addition, there is a limit to the amount that can be processed by one injection tube, and when processing a large amount of liquid phase, multiple tubes are required as shown in Fig. 6, and the manufacturing process increases as the strength decreases. was there. On the other hand, when the bar member is used, the above-mentioned problem of strength is solved, but the gas phase and the liquid phase are mixed at the outlet of the bar member where the passage is widened, so that there is a problem that the mixing property is poor. .
【０００６】 この考案は、上述した気液二相流熱交換器の問題を解消し、通路内で均質な気 液二相流体を得ることができ、かつプレートフィン型熱交換器の有する強度を損 なうことのない構成からなるプレートフィン型気液二相流熱交換器の提供を目的 としている。This invention solves the above-mentioned problems of the gas-liquid two-phase flow heat exchanger, can obtain a uniform gas-liquid two-phase fluid in the passage, and has the strength of the plate fin type heat exchanger. It is an object of the present invention to provide a plate fin type gas-liquid two-phase flow heat exchanger having a structure that does not damage it.

この考案によるプレートフィン型気液二相流熱交換器は、従来のインジェクシ ョンチューブに代えて特定構成の溝付きバーを通路に直交する方向に通路内のフ ィン間に挿入配置し、フィン及びプレートと一体的にろう付け固着できるため、 プレートフィン型熱交換器が有する強度を全く損なうことがない。 また、この考案によるプレートフィン型気液二相流熱交換器は、溝付きバーに は鉛直面に設けた水平方向溝と、鉛直方向の複数の貫通孔あるいは複数の鉛直方 向溝とが溝付きバー内の連通孔にて連通させて、通路外より水平方向溝に流入す る気相又は液相流体が、通路内の鉛直方向の気相又は液相流体に直接注入される ので均質に混合することができ構成であり、各溝の本数や貫通孔径は処理する流 体量に応じて適宜選定できるため、通路内で均質な気液二相流体を容易に得るこ とができる。 In the plate fin type gas-liquid two-phase heat exchanger according to the present invention, instead of the conventional injection tube, a grooved bar having a specific structure is inserted and arranged between the fins in the passage in a direction orthogonal to the passage, and Since it can be fixed to the plate by brazing, the strength of the plate fin type heat exchanger is not impaired at all.

A vapor phase fluid inlet header tank 4, a cooling medium outlet header tank 5 and a liquid phase fluid inlet header tank 6 are provided on the upper side, and a cooling medium inlet header tank 7 and a two-phase fluid outlet header tank 8 are provided on the lower side. The cooling medium in the cooling medium passage 2 is configured to cool the gas-liquid two-phase fluid mixed in the gas-liquid two-phase fluid passage 3. As shown in FIG. 1, the gas-liquid two-phase fluid passage 3 has a distribution fin 3a disposed in the upper portion of the passage and connected to a heat transfer fin 3c, and then a grooved bar 10 is disposed in the passage width direction. It is brazed to the hard way fin 3b, the plate and the side bar 9.
【００１１】 溝付きバー１０は図２のＡ，Ｂに示す如く、複数の鉛直方向の貫通孔１２を設 け、図で他方の鉛直面に１本の水平方向溝１１を設けてあり、複数の貫通孔１２ と水平方向溝１１底とがそれぞれ連通孔１３にて連通する構成からなる。 従って、気液二相流体通路３では、上部から分配フィン３ａ、伝熱フィン３ｃ を通って気相流体が流下してくるが、通路３幅方向に横断する溝付きバー１０の 位置で、気相流体が貫通孔１２を通過する際に、液相流体入口ヘッダータンク６ から流入してきた液相流体が水平方向溝１１から多数の連通孔１３を通過して気 相流体と混合されながら流下し、通路内で均質な気液二相流体を容易に得ること ができ、隣接する冷却媒体通路２の冷却媒体にて気液二相流体が冷却される。 また、図２に示す溝付きバー１０の１本の水平方向溝１１を、図３の溝付きバ ー２０に示す如く、３本の水平方向溝２１とすることにより、液相流体の気相流 体への混合をより均質化させるとともに液相量を増加させることができる。As shown in FIGS. 2A and 2B, the grooved bar 10 is provided with a plurality of vertical through holes 12, and one horizontal groove 11 is provided on the other vertical surface in the figure. The through hole 12 and the bottom of the horizontal groove 11 are communicated with each other through the communication hole 13. Therefore, in the gas-liquid two-phase fluid passage 3, the gas-phase fluid flows down from the upper portion through the distribution fins 3a and the heat transfer fins 3c, but at the position of the grooved bar 10 that crosses the passage 3 width direction, When the phase fluid passes through the through holes 12, the liquid phase fluid flowing from the liquid phase fluid inlet header tank 6 flows down from the horizontal groove 11 through the multiple communication holes 13 while being mixed with the gas phase fluid. It is possible to easily obtain a homogeneous gas-liquid two-phase fluid in the passage, and the gas-liquid two-phase fluid is cooled by the cooling medium in the adjacent cooling medium passage 2.

A plurality of vertical groove 32 bottoms and horizontal groove 31 bottoms are configured to communicate with each other through communication holes 33. Therefore, in the gas-liquid two-phase fluid passage 3, the gas-phase fluid flows down from the upper part through the distribution fins 3a and the heat transfer fins 3c, but at the position of the grooved bar 30 which crosses the passage 3 width direction, When the phase fluid passes through the vertical groove 32, the liquid phase fluid flowing in from the liquid phase fluid inlet header tank 6 passes from the horizontal groove 31 through a large number of communication holes 33, and then flows into the vertical groove 32. A homogeneous gas-liquid two-phase fluid can be easily obtained in the passage by flowing down while being mixed with the phase fluid. Also, instead of the horizontal groove 31 of the grooved bar 30 shown in FIG. 4A, as shown by the grooved bar 40 of FIG. Since the communication hole 43 to the bottom of the vertical groove 42 is inclined downward, when the liquid phase fluid from the horizontal groove 41 is mixed with the flow of the gas phase fluid passing through the vertical groove 42, The turbulence of the flow can be reduced.
