本発明の熱処理装置は、第１流体と第２流体との熱交換を利用する。以下、本実施形態に係る熱処置装置は、反応装置であるものとする。ただし、本発明は、例えば熱交換器などにも適用可能である。 The heat treatment apparatus of the present invention utilizes heat exchange between the first fluid and the second fluid. Hereinafter, the heat treatment device according to the present embodiment shall be a reaction device. However, the present invention can also be applied to, for example, heat exchangers.

図１は、本実施形態に係る反応装置１の構成を示す斜視分解図である。反応装置１は、熱交換型であり、反応体としての反応原料を含んだ気体又は液体の反応流体を加熱又は冷却することで、反応体の反応を進行させる。反応装置１は、本体部としての熱交換部１０１と、反応流体導入部１２０及び生成物排出部１２２と、熱媒体導入部１３０及び熱媒体排出部１３２とを備える。 FIG. 1 is a perspective exploded view showing the configuration of the reaction device 1 according to the present embodiment. The reactor 1 is a heat exchange type, and proceeds the reaction of the reactant by heating or cooling a gas or liquid reaction fluid containing a reaction raw material as a reactant. The reaction device 1 includes a heat exchange unit 101 as a main body unit, a reaction fluid introduction unit 120 and a product discharge unit 122, and a heat medium introduction unit 130 and a heat medium discharge unit 132.

図２は、熱交換部１０１の構成を示す断面図であり、特に、図２（ａ）は、図１におけるＡ−Ａ断面図を示し、図２（ｂ）は、図１におけるＢ−Ｂ断面図を示す。熱交換部１０１は、第１流体としての反応流体又は生成物が流通する反応流路と、第２流体としての熱媒体が流通する熱媒体流路とを含み、第１流体と第２流体とが互いに反対方向に流れる対向流型の構造を有する。 2A and 2B are cross-sectional views showing the configuration of the heat exchange unit 101. In particular, FIG. 2A shows a cross-sectional view taken along the line AA in FIG. 1, and FIG. 2B shows a cross-sectional view taken along the line BB in FIG. A cross-sectional view is shown. The heat exchange unit 101 includes a reaction flow path through which the reaction fluid or product as the first fluid flows, and a heat medium flow path through which the heat medium as the second fluid flows, and the first fluid and the second fluid Has a countercurrent structure in which water flows in opposite directions.

熱交換部１０１は、複数の伝熱体Ｐと、蓋体１４０とを備える。本実施形態では、一例として、鉛直方向の最上部に位置する伝熱体Ｐ１から最下部に位置する伝熱体Ｐ６までの計６つの伝熱体が存在するものとする。６つの伝熱体Ｐは、それぞれ、耐熱性を有する熱伝導性素材で形成される平板状部材であり、反応流路である第１流路ＦＰ１と、熱媒体流路である第２流路ＦＰ２とを有する。 The heat exchange unit 101 includes a plurality of heat transfer bodies P and a lid body 140. In the present embodiment, as an example, it is assumed that there are a total of six heat transfer bodies, from the heat transfer body P1 located at the uppermost part in the vertical direction to the heat transfer body P6 located at the lowermost part. Each of the six heat transfer bodies P is a flat plate-shaped member formed of a heat-resistant heat conductive material, and is a first flow path FP1 which is a reaction flow path and a second flow path which is a heat medium flow path. It has FP2.

まず、伝熱体Ｐ１は、それぞれ複数の第１流路ＦＰ１と第２流路ＦＰ２とを有し、本実施形態では、一例として、３つの第１流路ＦＰ１と、２つの第２流路ＦＰ２とを有する。第１流路ＦＰ１及び第２流路ＦＰ２は、それぞれ同じ方向に沿って延設されており、本実施形態ではＸ軸方向に沿って延設されている。また、第１流路ＦＰ１と第２流路ＦＰ２とは、壁部Ｐ１ａを介して交互に並設されている。 First, the heat transfer body P1 has a plurality of first flow paths FP1 and second flow path FP2, respectively, and in the present embodiment, as an example, three first flow paths FP1 and two second flow paths FP1. It has FP2. The first flow path FP1 and the second flow path FP2 are respectively extended along the same direction, and in the present embodiment, they are extended along the X-axis direction. Further, the first flow path FP1 and the second flow path FP2 are alternately arranged side by side via the wall portion P1a.

第１流路ＦＰ１は、第２流路ＦＰ２を流通する熱媒体から供給された熱又は冷熱を受容して反応流体を反応させ、生成物を生成する。また、第１流路ＦＰ１は、鉛直方向上方を開とし、伝熱体Ｐ１の一方の端部の壁面から他方の端部の壁面まで一直線で貫通する溝である。さらに、不図示であるが、第１流路ＦＰ１には、反応体の反応を促進させるための触媒体を設置してもよい。なお、触媒体については、以下で詳説する。 The first flow path FP1 receives heat or cold heat supplied from the heat medium flowing through the second flow path FP2 and reacts the reaction fluid to produce a product. Further, the first flow path FP1 is a groove that opens upward in the vertical direction and penetrates straight from the wall surface of one end of the heat transfer body P1 to the wall surface of the other end. Further, although not shown, a catalyst body for accelerating the reaction of the reactant may be installed in the first flow path FP1. The catalyst will be described in detail below.

第２流路ＦＰ２は、熱媒体から供給された熱又は冷熱を、第１流路ＦＰ１に向けて供給する。また、第２流路ＦＰ２は、鉛直方向上方を開とし、互いに対向する２つの壁部Ｐ１ａと、互いに対向する２つの壁部Ｐ１ｂとで側面四方を囲まれる溝である。さらに、不図示であるが、第２流路ＦＰ２には、熱媒体との接触面積を増加させて熱媒体と伝熱体Ｐとの間の伝熱を促進するための伝熱促進体を設置してもよい。伝熱促進体は、伝熱体Ｐとの接触面積を確保するために、コルゲート板状とし得る。また、伝熱促進体を構成する熱伝導性素材としては、アルミニウム、銅、ステンレス鋼、鉄系メッキ鋼等の金属が挙げられる。 The second flow path FP2 supplies heat or cold heat supplied from the heat medium toward the first flow path FP1. Further, the second flow path FP2 is a groove that opens upward in the vertical direction and is surrounded on all four sides by two wall portions P1a facing each other and two wall portions P1b facing each other. Further, although not shown, a heat transfer promoter is installed in the second flow path FP2 to increase the contact area with the heat medium and promote heat transfer between the heat medium and the heat transfer body P. You may. The heat transfer promoter may have a corrugated plate shape in order to secure a contact area with the heat transfer body P. Further, examples of the heat conductive material constituting the heat transfer promoter include metals such as aluminum, copper, stainless steel, and iron-based plated steel.

伝熱体Ｐ２は、鉛直方向の上部で伝熱体Ｐ１に接合される伝熱体である。伝熱体Ｐ１と同様に、伝熱体Ｐ２も、複数の第１流路ＦＰ１と第２流路ＦＰ２とを有し、第１流路ＦＰ１及び第２流路ＦＰ２は、Ｘ軸方向に沿って延設され、壁部Ｐ２ａを介して交互に並設されている。ただし、伝熱体Ｐ２の第１流路ＦＰ１及び第２流路ＦＰ２は、伝熱体Ｐ１の第１流路ＦＰ１及び第２流路ＦＰ２の位置に対して、延設方向であるＸ軸方向と接合方向であるＺ軸方向とにそれぞれ垂直となるＹ軸方向に、ずれて形成されている。したがって、伝熱体Ｐ２は、２つの第１流路ＦＰ１と、３つの第２流路ＦＰ２とを有することになる。 The heat transfer body P2 is a heat transfer body bonded to the heat transfer body P1 at the upper part in the vertical direction. Like the heat transfer body P1, the heat transfer body P2 also has a plurality of first flow paths FP1 and second flow path FP2, and the first flow path FP1 and the second flow path FP2 are along the X-axis direction. It is extended and alternately arranged side by side via the wall portion P2a. However, the first flow path FP1 and the second flow path FP2 of the heat transfer body P2 are in the X-axis direction which is the extension direction with respect to the positions of the first flow path FP1 and the second flow path FP2 of the heat transfer body P1. It is formed so as to be offset in the Y-axis direction which is perpendicular to the Z-axis direction which is the joining direction. Therefore, the heat transfer body P2 has two first flow paths FP1 and three second flow paths FP2.

伝熱体Ｐ２の下部に接合される伝熱体Ｐ３は、伝熱体Ｐ１と同様の形状を有する。伝熱体Ｐ３の下部に接合される伝熱体Ｐ４は、伝熱体Ｐ２と同様の形状を有する。伝熱体Ｐ４の下部に接合される伝熱体Ｐ５は、伝熱体Ｐ１と同様の形状を有する。また、伝熱体Ｐ５の下部に接合される伝熱体Ｐ６は、伝熱体Ｐ２と同様の形状を有する。すなわち、それぞれの伝熱体Ｐに形成されている第１流路ＦＰ１及び第２流路ＦＰ２の位置は、伝熱体Ｐ一つおきに同じとなる。 The heat transfer body P3 joined to the lower part of the heat transfer body P2 has the same shape as the heat transfer body P1. The heat transfer body P4 joined to the lower part of the heat transfer body P3 has the same shape as the heat transfer body P2. The heat transfer body P5 joined to the lower part of the heat transfer body P4 has the same shape as the heat transfer body P1. Further, the heat transfer body P6 joined to the lower part of the heat transfer body P5 has the same shape as the heat transfer body P2. That is, the positions of the first flow path FP1 and the second flow path FP2 formed in each heat transfer body P are the same for every other heat transfer body P.

蓋体１４０は、伝熱体Ｐ１の鉛直方向の上部に設置される平板部材である。そして、図１に示すように、平板面を水平として、鉛直方向に伝熱体Ｐ６から順にそれぞれの伝熱体Ｐと蓋体１４０とを接合することで、接合体又は積層体としての熱交換部１０１が形成される。熱交換部１０１の組み立ての際には、各部材間をＴＩＧ（Tungsten Inert Gas）溶接や拡散接合等のような接合方法を利用して固着させることで、各部材間の接触不良に起因する伝熱性の低下等が抑止される。 The lid 140 is a flat plate member installed on the upper portion of the heat transfer body P1 in the vertical direction. Then, as shown in FIG. 1, heat exchange as a bonded body or a laminated body is performed by joining the heat transfer bodies P and the lid 140 in order from the heat transfer body P6 in the vertical direction with the flat plate surface horizontal. Part 101 is formed. When assembling the heat exchange section 101, the members are fixed by using a joining method such as TIG (Tungsten Inert Gas) welding or diffusion welding, so that the heat exchange section 101 is transmitted due to poor contact between the members. The decrease in heat is suppressed.

ここで、第１流路ＦＰ１は、それぞれ、反応流体を熱交換部１０１の外部から導入する開口と、生成物を熱交換部１０１の外部に放出する開口とを直接的に有している。一方、第２流路ＦＰ２は、それぞれ、伝熱体Ｐの内部に形成されているため、熱交換部１０１の外部に直接的に開放されている開口を有していない。そこで、伝熱体Ｐは、それぞれ、第２流路ＦＰ２の一方の端部に連通し、伝熱体Ｐ及び蓋体１４０の接合方向に沿って設けられる第１連通路ＦＰ３と、第２流路ＦＰ２の他方の端部に連通し、同様に接合方向に沿って設けられる第２連通路ＦＰ４とを有する。 Here, each of the first flow path FP1 directly has an opening for introducing the reaction fluid from the outside of the heat exchange unit 101 and an opening for discharging the product to the outside of the heat exchange unit 101. On the other hand, since each of the second flow paths FP2 is formed inside the heat transfer body P, it does not have an opening that is directly open to the outside of the heat exchange unit 101. Therefore, the heat transfer body P communicates with one end of the second flow path FP2, respectively, and is provided along the joining direction of the heat transfer body P and the lid 140, the first continuous passage FP3 and the second flow. It has a second passage FP4 that communicates with the other end of the road FP2 and is also provided along the joining direction.

具体的には、図２（ａ）に示すように、伝熱体Ｐ１〜伝熱体Ｐ５に形成されている第１連通路ＦＰ３は、それぞれ接合方向に貫通している。そして、熱交換部１０１の最下部に位置する伝熱体Ｐ６に形成されている第１連通路ＦＰ３のみ、第２流体が熱交換部１０１の底部から放出されないように、貫通していない。また、それぞれの伝熱体Ｐに形成されている第１連通路ＦＰ３は、熱交換部１０１としてそれぞれの伝熱体Ｐが接合されている状態で、それぞれ連通している。すなわち、組み合わされた第１連通路ＦＰ３は、伝熱体Ｐ１の上面にある１つの開口を通じて外部に開放されることになる。なお、第２連通路ＦＰ４も、第１連通路ＦＰ３と同一形状である。 Specifically, as shown in FIG. 2A, the first passage FP3 formed in the heat transfer bodies P1 to the heat transfer body P5 penetrates in the joining direction, respectively. Then, only the first passage FP3 formed in the heat transfer body P6 located at the lowermost portion of the heat exchange portion 101 does not penetrate so that the second fluid is not discharged from the bottom portion of the heat exchange portion 101. Further, the first communication passage FP3 formed in each heat transfer body P communicates with each other in a state where each heat transfer body P is joined as a heat exchange portion 101. That is, the combined first passage FP3 is opened to the outside through one opening on the upper surface of the heat transfer body P1. The second passage FP4 also has the same shape as the first passage FP3.

熱交換部１０１を構成する各要素の熱伝導性素材としては、鉄系合金やニッケル合金等の耐熱性金属が好適である。具体的には、ステンレス綱等の鉄系合金、インコネル６２５（登録商標）、インコネル６１７（登録商標）、Ｈａｙｎｅｓ２３０（登録商標）等のニッケル合金のような耐熱合金が挙げられる。これらの熱伝導性素材は、第１流路ＦＰ１での反応進行や熱媒体として使用し得る燃焼ガスに対する耐久性又は耐食性を有するので好ましいが、これらに限定されるものではない。また、鉄系メッキ鋼や、フッ素樹脂等の耐熱樹脂で被覆した金属、又は、カーボングラファイト等でもよい。 As the heat conductive material of each element constituting the heat exchange unit 101, a heat-resistant metal such as an iron alloy or a nickel alloy is suitable. Specific examples thereof include iron-based alloys such as stainless steel, and heat-resistant alloys such as nickel alloys such as Inconel 625 (registered trademark), Inconel 617 (registered trademark), and Haynes 230 (registered trademark). These thermally conductive materials are preferable because they have durability or corrosion resistance against combustion gas that can be used as a heat medium and the reaction progress in the first flow path FP1, but are not limited thereto. Further, iron-based plated steel, a metal coated with a heat-resistant resin such as fluororesin, carbon graphite, or the like may be used.

なお、熱交換部１０１は、少なくとも２つの伝熱体Ｐを用いても構成可能である。ただし、熱交換性能を向上させる観点から、伝熱体Ｐの数は多い方が望ましい。また、１つの伝熱体Ｐに形成される第１流路ＦＰ１及び第２流路ＦＰ２の数も、特に限定されるものではなく、熱交換部１０１の設計条件や伝熱効率などを考慮して適宜変更可能である。さらに、本実施形態では、熱交換部１０１自体を反応装置１の本体部と位置付けているが、熱交換部１０１からの放熱を抑制して熱損失を抑えるために、ハウジング又は断熱材で熱交換部１０１の周囲を覆う構成としてもよい。 The heat exchange unit 101 can also be configured by using at least two heat transfer bodies P. However, from the viewpoint of improving the heat exchange performance, it is desirable that the number of heat transfer bodies P is large. Further, the number of the first flow path FP1 and the second flow path FP2 formed in one heat transfer body P is not particularly limited, and the design conditions of the heat exchange unit 101, the heat transfer efficiency, and the like are taken into consideration. It can be changed as appropriate. Further, in the present embodiment, the heat exchange unit 101 itself is positioned as the main body of the reaction device 1, but in order to suppress heat dissipation from the heat exchange unit 101 and suppress heat loss, heat exchange is performed with a housing or a heat insulating material. It may be configured to cover the periphery of the portion 101.

反応流体導入部１２０は、凹状に湾曲した筐体であり、複数の第１流路ＦＰ１が上流側で開放されている側の熱交換部１０１の側面を覆い、熱交換部１０１との間に空間を形成する。反応流体導入部１２０は、熱交換部１０１に対して着脱可能又は開閉可能に設置される。この着脱等により、例えば、作業者が第１流路ＦＰ１に対する触媒体の挿入や抜き出しを行うことができる。また、反応流体導入部１２０は、反応流体を熱交換部１０１の外部から内部へ導入する導入配管１２０ａを有する。導入配管１２０ａは、図１に示すように、熱交換部１０１の側面に対して中心、具体的にはＹＺ平面上の中心に位置し、複数の第１流路ＦＰ１の開口方向と同一方向に連接されている。これにより、導入配管１２０ａは、第１流路ＦＰ１のそれぞれに、反応流体をバランス良く分配することができる。 The reaction fluid introduction unit 120 is a concavely curved housing, covers the side surface of the heat exchange unit 101 on the side where the plurality of first flow paths FP1 are open on the upstream side, and is between the reaction fluid introduction unit 120 and the heat exchange unit 101. Form a space. The reaction fluid introduction unit 120 is installed so as to be removable or openable / closable with respect to the heat exchange unit 101. By this attachment / detachment or the like, for example, the operator can insert or remove the catalyst body from the first flow path FP1. Further, the reaction fluid introduction unit 120 has an introduction pipe 120a for introducing the reaction fluid from the outside to the inside of the heat exchange unit 101. As shown in FIG. 1, the introduction pipe 120a is located at the center with respect to the side surface of the heat exchange portion 101, specifically at the center on the YZ plane, and is in the same direction as the opening direction of the plurality of first flow paths FP1. It is connected. As a result, the introduction pipe 120a can distribute the reaction fluid to each of the first flow paths FP1 in a well-balanced manner.

生成物排出部１２２は、反応流体導入部１２０と同様に、凹状に湾曲した筐体であり、複数の第１流路ＦＰ１が下流側で開放されている側の熱交換部１０１の側面を覆い、熱交換部１０１との間に空間を形成する。生成物排出部１２２は、反応流体導入部１２０と同様に熱交換部１０１に対して着脱可能又は開閉可能に設置されるものとしてもよいが、反応流体導入部１２０が着脱可能等に構成されているのであれば、着脱等不可能であってもよい。その反対に、生成物排出部１２２が着脱可能等に構成されているのであれば、反応流体導入部１２０が着脱等不可能であってもよい。また、生成物排出部１２２は、生成物を熱交換部１０１の内部から外部へ排出する排出配管１２２ａを有する。排出配管１２２ａも、図１に示すように、熱交換部１０１の側面に対して中心、具体的にはＹＺ平面上の中心に位置し、複数の第１流路ＦＰ１の開口方向と同一方向に連接されている。これにより、排出配管１２２ａは、第１流路ＦＰ１のそれぞれから、効率良く生成物を回収しつつ排出させることができる。 The product discharge unit 122 is a concavely curved housing similar to the reaction fluid introduction unit 120, and covers the side surface of the heat exchange unit 101 on the side where the plurality of first flow paths FP1 are open on the downstream side. , A space is formed between the heat exchange unit 101 and the heat exchange unit 101. The product discharge unit 122 may be installed in a detachable or openable / closable manner with respect to the heat exchange unit 101 like the reaction fluid introduction unit 120, but the reaction fluid introduction unit 120 is configured to be detachable and the like. If so, it may not be possible to attach or detach it. On the contrary, if the product discharge unit 122 is configured to be removable, the reaction fluid introduction unit 120 may not be removable. In addition, the product discharge unit 122 has a discharge pipe 122a that discharges the product from the inside of the heat exchange unit 101 to the outside.

In particular, examples of carriers that can be used for the gaseous reaction fluid include gaseous carriers such as an inert gas and a low-reactivity gaseous substance. On the other hand, as the heat medium, a fluid substance that does not corrode the constituent material of the reactor 1 is preferable, and for example, a liquid substance such as water or oil or a gaseous substance such as combustion gas can be used. The configuration in which a gaseous substance is used as the heat medium is easier to handle as compared with the case where a liquid medium is used.

To. Examples of the active metal as a catalyst component include Ni (nickel), Co (cobalt), Fe (iron), Pt (platinum), Ru (ruthenium), Rh (rhodium), Pd (palladium) and the like.

次に、本実施形態による作用及び効果について説明する。 Next, the action and effect of this embodiment will be described.

まず、第１流体と第２流体との熱交換を利用する熱処理装置は、第１流体を流通させる第１流路ＦＰ１と、第２流体を流通させる第２流路ＦＰ２とが壁部を介して並設されている第１伝熱体と、第１流体を流通させる第１流路ＦＰ１と、第２流体を流通させる第２流路ＦＰ２とが壁部を介して並設され、第１伝熱体に接合される第２伝熱体と、を備え、第２伝熱体が有する第１流路ＦＰ１の少なくとも一部は、第１伝熱体が有する第２流路ＦＰ２の少なくとも一部と、接合方向で、かつ、非接触で重なる。 First, in the heat treatment apparatus that utilizes heat exchange between the first fluid and the second fluid, the first flow path FP1 that circulates the first fluid and the second flow path FP2 that circulates the second fluid pass through the wall portion. The first heat transfer body, the first flow path FP1 for passing the first fluid, and the second flow path FP2 for passing the second fluid are arranged side by side via the wall portion, and the first A second heat transfer body bonded to the heat transfer body is provided, and at least a part of the first flow path FP1 of the second heat transfer body is at least one of the second flow path FP2 of the first heat transfer body. It overlaps with the part in the joining direction and in a non-contact manner.

ただし、熱処理装置は、本実施形態では反応装置１に相当する。第１流体は、反応流体又は生成物とし、第２流体は、熱媒体とし得る。また、第１伝熱体が本実施形態における伝熱体Ｐ２に相当するとすれば、第２伝熱体は、伝熱体Ｐ３に相当する。また、第１伝熱体が伝熱体Ｐ１に相当するとすれば、第１伝熱体の壁部は、壁部Ｐ１ａに相当する。なお、その他の伝熱体Ｐ２〜伝熱体Ｐ６に設けられている壁部Ｐ２ａ〜Ｐ６ａについても同様である。ここで、少なくとも一部と表現しているのは、第２伝熱体の第１流路ＦＰ１の一部と第１伝熱体の第２流路ＦＰ２の一部とが上記のように重なる場合を包含するだけではないからである。すなわち、以下で詳説するが、ここでは、第２伝熱体の第１流路ＦＰ１と、第１伝熱体の第２流路ＦＰ２とが、接合方向で、かつ、非接触で、完全に重なる場合も包含している。 However, the heat treatment apparatus corresponds to the reaction apparatus 1 in this embodiment. The first fluid can be a reaction fluid or product and the second fluid can be a heat medium. Further, if the first heat transfer body corresponds to the heat transfer body P2 in the present embodiment, the second heat transfer body corresponds to the heat transfer body P3. Further, if the first heat transfer body corresponds to the heat transfer body P1, the wall portion of the first heat transfer body corresponds to the wall portion P1a. The same applies to the wall portions P2a to P6a provided on the other heat transfer bodies P2 to P6. Here, what is expressed as at least a part is that a part of the first flow path FP1 of the second heat transfer body and a part of the second flow path FP2 of the first heat transfer body overlap as described above. This is because it does not only include cases. That is, as will be described in detail below, here, the first flow path FP1 of the second heat transfer body and the second flow path FP2 of the first heat transfer body are completely in the joining direction and in a non-contact manner. It also includes cases where they overlap.

本実施形態に係る熱処理装置によれば、第１に、第１流路ＦＰ１は、側面の壁部を介して並設されている第２流路ＦＰ２から熱を受ける。すなわち、第１流路ＦＰ１は、延設方向及び接合方向に対して垂直となる図中左右方向から熱を受けることができる。第２に、第１流路ＦＰ１は、その第１流路ＦＰ１を有する伝熱体Ｐに接合されている他の伝熱体Ｐが有する第２流路ＦＰ２から熱を受ける。すなわち、第１流路ＦＰ１は、接合方向、具体的には、図中上下斜め方向から熱を受けることができる。したがって、反応流路が接合方向からしか熱を受けることができない従来の熱処理装置に比べて、その伝熱面積を増加させることができ、その結果、第１流体に与える熱供給量を増加させることができる。 According to the heat treatment apparatus according to the present embodiment, first, the first flow path FP1 receives heat from the second flow path FP2 arranged side by side via the side wall portion. That is, the first flow path FP1 can receive heat from the left and right directions in the figure which are perpendicular to the extending direction and the joining direction. Secondly, the first flow path FP1 receives heat from the second flow path FP2 of another heat transfer body P bonded to the heat transfer body P having the first flow path FP1. That is, the first flow path FP1 can receive heat from the joining direction, specifically, from the vertical diagonal direction in the drawing. Therefore, the heat transfer area can be increased as compared with the conventional heat treatment apparatus in which the reaction flow path can receive heat only from the joining direction, and as a result, the amount of heat supplied to the first fluid can be increased. Can be done.

また、本実施形態に係る熱処理装置では、第２伝熱体が有する第１流路ＦＰ１の少なくとも一部は、更に、第１伝熱体が有する第１流路ＦＰ１の少なくとも一部と、接合方向で、かつ、非接触で重なる。 Further, in the heat treatment apparatus according to the present embodiment, at least a part of the first flow path FP1 of the second heat transfer body is further joined with at least a part of the first flow path FP1 of the first heat transfer body. Overlapping in a directional and non-contact manner.

本実施形態に係る熱処理装置によれば、第２伝熱体の第１流路ＦＰ１は、結果的に、図１及び図２に示すように、第１伝熱体の第１流路ＦＰ１及び第２流路ＦＰ２の両方に対して一部が重なることになる。したがって、伝熱面積を従来よりも増加させる観点と、伝熱体Ｐの横幅、すなわち第１流路ＦＰ１と第２流路ＦＰ２とが並設される方向の幅を可能な限り縮小させる観点との双方を考慮した場合に、最も効率がよい。 According to the heat treatment apparatus according to the present embodiment, the first flow path FP1 of the second heat transfer body eventually becomes the first flow path FP1 of the first heat transfer body and as shown in FIGS. 1 and 2. A part of the second flow path FP2 overlaps with each other. Therefore, there is a viewpoint of increasing the heat transfer area as compared with the conventional case and a viewpoint of reducing the width of the heat transfer body P, that is, the width in the direction in which the first flow path FP1 and the second flow path FP2 are arranged side by side as much as possible. It is the most efficient when both of the above are taken into consideration.

また、本実施形態に係る熱処理装置では、第２伝熱体が有する第１流路ＦＰ１と、第１伝熱体が有する第２流路ＦＰ２とが重なる割合ｘは、第１流路ＦＰ１及び第２流路ＦＰ２の接合方向の流路高さをＨとし、第１流路ＦＰ１及び第２流路ＦＰ２の流路幅をＷとすると、ｘ＞１−（Ｈ／Ｗ）との条件を満たす。 Further, in the heat treatment apparatus according to the present embodiment, the ratio x in which the first flow path FP1 of the second heat transfer body and the second flow path FP2 of the first heat transfer body overlap is the first flow path FP1 and Assuming that the flow path height in the joining direction of the second flow path FP2 is H and the flow path widths of the first flow path FP1 and the second flow path FP2 are W, the condition of x> 1- (H / W) is satisfied. Fulfill.

本実施形態に係る熱処理装置によれば、熱交換部１０１を構成する伝熱体Ｐの設置数を従来に比べて減らすことも可能である。図３は、熱交換部１０１における第１流路ＦＰ１と第２流路ＦＰ２との位置関係の詳細を示す拡大断面図である。ここでは、一例として、伝熱体Ｐ２に形成されている第２流路ＦＰ２と、伝熱体Ｐ２の下部に接合されている伝熱体Ｐ３に形成されている第１流路ＦＰ１とについて考える。 According to the heat treatment apparatus according to the present embodiment, it is possible to reduce the number of heat transfer bodies P installed in the heat exchange unit 101 as compared with the conventional case. FIG. 3 is an enlarged cross-sectional view showing details of the positional relationship between the first flow path FP1 and the second flow path FP2 in the heat exchange unit 101. Here, as an example, consider the second flow path FP2 formed in the heat transfer body P2 and the first flow path FP1 formed in the heat transfer body P3 joined to the lower part of the heat transfer body P2. ..

ここで、本実施形態における流路配置では、第１流路ＦＰ１は、延設方向視で上下左右に存在する第２流路ＦＰ２から熱を受けるので、伝熱面積は、（２×Ｈ）＋（２×ｘＷ）となる。一方、従来の流路配置では、反応流路及び熱媒体流路の寸法が上記と同様であるとすると、反応流路は、延設方向視で上下に存在する熱媒体流路からしか熱を受けないので、伝熱面積は、（２×Ｗ）となる。このことから、本実施形態における流路配置が、従来の流路配置よりも伝熱性能を向上させるものとなるためには、（２×Ｈ）＋（２×ｘＷ）＞（２×Ｗ）の式が成り立ち、すなわち、割合ｘが、ｘ＞１−（Ｈ／Ｗ）の条件を満たせばよい。したがって、この点を考慮して伝熱体Ｐを設計すれば、従来の熱交換部と比較して、伝熱面積を同等か又は向上させつつ、伝熱体Ｐの設置数を半分程度にまで減らすことができる。 Here, in the flow path arrangement in the present embodiment, since the first flow path FP1 receives heat from the second flow path FP2 existing in the vertical and horizontal directions in the extending direction, the heat transfer area is (2 × H). It becomes + (2 × xW). On the other hand, in the conventional flow path arrangement, assuming that the dimensions of the reaction flow path and the heat medium flow path are the same as above, the reaction flow path receives heat only from the heat medium flow paths existing above and below in the extending direction. Since it does not receive heat, the heat transfer area is (2 × W). From this, in order for the flow path arrangement in the present embodiment to improve the heat transfer performance as compared with the conventional flow path arrangement, (2 × H) + (2 × x W)> (2 × W). That is, the ratio x may satisfy the condition of x> 1- (H / W). Therefore, if the heat transfer body P is designed in consideration of this point, the number of heat transfer bodies P installed can be reduced to about half while the heat transfer area is equal to or improved as compared with the conventional heat exchange unit. Can be reduced.

さらに、本実施形態に係る熱処理装置では、第１伝熱体及び第２伝熱体は、第１伝熱体が有する第２流路ＦＰ２と、第２伝熱体が有する第２流路ＦＰ２とを連通させる連通路ＦＰ３，ＦＰ４を有する。 Further, in the heat treatment apparatus according to the present embodiment, the first heat transfer body and the second heat transfer body are the second flow path FP2 of the first heat transfer body and the second flow path FP2 of the second heat transfer body. It has communication passages FP3 and FP4 for communicating with and.

本実施形態に係る熱処理装置によれば、第１伝熱体及び第２伝熱体の内部に第１連通路ＦＰ３及び第２連通路ＦＰ４を設け、熱交換部１０１の内部に存在する複数の第２流路ＦＰ２を外部に連通させる。したがって、第１に、第１連通路ＦＰ３及び第２連通路ＦＰ４が熱交換部１０１の内部に存在することから、流路内の耐圧の点で有利となる。第２に、熱交換部１０１の側面などに、別途、連通路となる配管や筐体等を接続させる必要がないので、装置構成が簡略化し、また、第１連通路ＦＰ３及び第２連通路ＦＰ４の形成も、単に孔を開けるのみであるので簡単化するという利点がある。 According to the heat treatment apparatus according to the present embodiment, a plurality of first-passage FP3 and second-passage FP4 are provided inside the first heat transfer body and the second heat transfer body, and a plurality of heat exchange units 101 exist inside. The second flow path FP2 is communicated to the outside. Therefore, firstly, since the first passage FP3 and the second passage FP4 are present inside the heat exchange section 101, it is advantageous in terms of pressure resistance in the flow path. Secondly, since it is not necessary to separately connect a pipe, a housing, or the like to be a continuous passage to the side surface of the heat exchange unit 101, the device configuration is simplified, and the first continuous passage FP3 and the second continuous passage are not required. The formation of FP4 also has an advantage of being simplified because it merely makes a hole.

（他の実施形態）
なお、上記触れたように、本発明では、第２伝熱体の第１流路ＦＰ１と、第１伝熱体の第２流路ＦＰ２とが、接合方向で、かつ、非接触で、完全に重なる場合もあり得る。図４は、この場合について説明するための熱交換部１０１の他の構成を示す断面図である。上記実施形態では、第２伝熱体の第１流路ＦＰ１と第１伝熱体の第２流路ＦＰ２とが接合方向で完全に重なるまでずれているわけではないので、第１連通路ＦＰ３及び第２連通路ＦＰ４を、図２（ａ）に示すように一直線状に形成することができる。第１連通路ＦＰ３及び第２連通路ＦＰ４が一直線状であることは、第１連通路ＦＰ３及び第２連通路ＦＰ４を形成する上で容易となる。これに対して、図４に示すような構成では、第２伝熱体の第１流路ＦＰ１と第１伝熱体の第２流路ＦＰ２とが接合方向で完全に重なっているので、第１連通路ＦＰ３は、例えば、第２流路ＦＰ２に連通する連通路ＦＰ３ａと、接合方向に対して傾斜している連通路ＦＰ３ｂとを組み合わせて構成されることになる。これは、第２連通路ＦＰ４についても、同様である。この場合、第１連通路ＦＰ３及び第２連通路ＦＰ４を形成する工程が、上記の実施形態と比較して複雑となるが、伝熱面積をより増加させる点では有利となる。 (Other embodiments)
As mentioned above, in the present invention, the first flow path FP1 of the second heat transfer body and the second flow path FP2 of the first heat transfer body are completely in the joining direction and in a non-contact manner. It may overlap with. FIG. 4 is a cross-sectional view showing another configuration of the heat exchange unit 101 for explaining this case. In the above embodiment, the first flow path FP1 of the second heat transfer body and the second flow path FP2 of the first heat transfer body are not displaced until they completely overlap in the joining direction, so that the first continuous passage FP3 And the second passage FP4 can be formed in a straight line as shown in FIG. 2A. The fact that the first passage FP3 and the second passage FP4 are linear makes it easy to form the first passage FP3 and the second passage FP4. On the other hand, in the configuration shown in FIG. 4, the first flow path FP1 of the second heat transfer body and the second flow path FP2 of the first heat transfer body completely overlap in the joining direction. The single passage FP3 is configured by, for example, combining a communication passage FP3a communicating with the second flow path FP2 and a communication passage FP3b inclined with respect to the joining direction. This also applies to the second passage FP4. In this case, the step of forming the first passage FP3 and the second passage FP4 becomes complicated as compared with the above embodiment, but it is advantageous in that the heat transfer area is further increased.

また、第１流体と第２流体とは、本発明が適用される熱処理装置によっては、それぞれ異なる物質となる場合も、同一の物質となる場合もあり得る。また、上記実施形態では、第１流体が反応流体又は生成物で、第２流体が熱媒体であるものとしたが、それぞれ反対とすることも可能である。さらに、本発明が適用される熱処理装置が熱交換器であるならば、第１流体及び第２流体ともに、熱媒体となる場合もあり得る。 Further, the first fluid and the second fluid may be different substances or the same substance depending on the heat treatment apparatus to which the present invention is applied. Further, in the above embodiment, the first fluid is a reaction fluid or a product, and the second fluid is a heat medium, but the opposite is also possible. Further, if the heat treatment apparatus to which the present invention is applied is a heat exchanger, both the first fluid and the second fluid may be heat media.

また、上記実施形態では、伝熱体Ｐごとに並設される２種類の形状の流路、すなわち、伝熱体Ｐの一方の端部の壁面から他方の端部の壁面まで一直線で貫通する第１流路ＦＰ１と、側面四方を壁部Ｐ１ａ，Ｐ１ｂで囲まれる第２流路ＦＰ２とを例示した。しかしながら、第１流路ＦＰ１及び第２流路ＦＰ２の形状は、それぞれ上記のような形状に限定されるものではない。例えば、第１流路ＦＰ１及び第２流路ＦＰ２ともに、１つの方向に延設される溝の一端が、上記の第１流路ＦＰ１の例示と同様に、伝熱体Ｐの一方の端部の壁面から貫通し、他端が、上記の第２流路ＦＰ２の例示と同様に、連通路に連接されるものとしてもよい。 Further, in the above embodiment, two types of flow paths arranged side by side for each heat transfer body P, that is, penetrating in a straight line from the wall surface of one end of the heat transfer body P to the wall surface of the other end. The first flow path FP1 and the second flow path FP2 whose side surfaces are surrounded by wall portions P1a and P1b are illustrated. However, the shapes of the first flow path FP1 and the second flow path FP2 are not limited to the above-mentioned shapes, respectively. For example, in both the first flow path FP1 and the second flow path FP2, one end of the groove extending in one direction is one end of the heat transfer body P, as in the above example of the first flow path FP1. The other end of the second flow path FP2 may be connected to the communication path as in the above example of the second flow path FP2.

また、上記実施形態では、熱交換部１０１が、第１流路ＦＰ１を流通する第１流体と第２流路ＦＰ２を流通する第２流体とが互いに反対方向に流れる対向流型であるものとしたが、互いに同方向に流れる並流型であってもよい。さらに、本発明では、第１流体と第２流体とが流れる方向についても、なんら限定されるものではない。 Further, in the above embodiment, the heat exchange unit 101 is of a countercurrent type in which the first fluid flowing through the first flow path FP1 and the second fluid flowing through the second flow path FP2 flow in opposite directions. However, it may be a parallel flow type that flows in the same direction as each other. Further, in the present invention, the direction in which the first fluid and the second fluid flow is not limited at all.

さらに、上記実施形態では、熱交換部１０１を構成する６つの伝熱体Ｐが鉛直方向に接合すなわち積層されるものとしているが、本発明は、これに限られない。例えば、熱交換部１０１を構成する６つの伝熱体Ｐが、それぞれ接合されて鉛直方向に立設するような、いわゆる横置きとして使用されるものとしてもよい。 Further, in the above embodiment, the six heat transfer bodies P constituting the heat exchange unit 101 are joined or laminated in the vertical direction, but the present invention is not limited to this. For example, the six heat transfer bodies P constituting the heat exchange unit 101 may be used as a so-called horizontal installation in which the six heat transfer bodies P are joined to each other and stand upright in the vertical direction.

以上、本発明の好ましい実施形態について説明したが、本発明は、この実施形態に限定されず、その要旨の範囲内で種々の変形及び変更が可能である。 Although the preferred embodiment of the present invention has been described above, the present invention is not limited to this embodiment, and various modifications and modifications can be made within the scope of the gist thereof.
