Hereinafter, the heat treatment apparatus according to the present embodiment is a reaction apparatus. However, the present invention can also be applied to, for example, a heat exchanger.

  FIG. 1 is an exploded perspective view showing a configuration of a reaction apparatus 1 according to the present embodiment. The reaction apparatus 1 is a heat exchange type, and heats or cools a gaseous or liquid reaction fluid containing a reaction raw material as a reactant to advance the reaction of the reactant. The reaction apparatus 1 includes a heat exchange unit 101 as a main body, a reaction fluid introduction unit 120 and a product discharge unit 122, a heat medium introduction unit 130, and a heat medium discharge unit 132.

  2 is a cross-sectional view showing a configuration of the heat exchange unit 101. In particular, FIG. 2A shows a cross-sectional view taken along line AA in FIG. 1, and FIG. 2B shows a cross-sectional view taken along line BB in FIG. A cross-sectional view is shown. The heat exchange unit 101 includes a reaction channel through which a reaction fluid or a product as a first fluid flows, and a heat medium channel through which a heat medium as a second fluid flows, and the first fluid and the second fluid Have counter-flow type structures that flow in opposite directions.

  The heat exchanging 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 top in the vertical direction to the heat transfer body P6 located at the bottom. Each of the six heat transfer bodies P is a flat plate member formed of a heat conductive material having heat resistance, and includes a first flow path FP1 that is a reaction flow path and a second flow path that is a heat medium flow path. FP2.

  First, each heat transfer body P1 has a plurality of first flow paths FP1 and second flow paths FP2, and in the present embodiment, as an example, three first flow paths FP1 and two second flow paths FP2. FP2. The first flow path FP1 and the second flow path FP2 are each extended along the same direction, and in the present embodiment, are extended along the X-axis direction. The first flow path FP1 and the second flow path FP2 are alternately arranged in parallel via the wall portion P1a.

  The first flow path FP1 receives heat or cold supplied from the heat medium flowing through the second flow path FP2 and reacts the reaction fluid to generate a product. The first flow path FP1 is a groove that opens in the vertical direction and penetrates in a straight line 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 promoting the reaction of the reactants may be installed in the first flow path FP1. The catalyst body will be described in detail below.

  The second flow path FP2 supplies heat or cold supplied from the heat medium toward the first flow path FP1. Further, the second flow path FP2 is a groove that is open in the upper part in the vertical direction and is surrounded on the four sides by two wall portions P1a facing each other and two wall portions P1b facing each other. Furthermore, although not shown in the drawing, the second flow path FP2 is provided with a heat transfer promoting body for increasing the contact area with the heat medium and promoting heat transfer between the heat medium and the heat transfer body P. May be. In order to secure a contact area with the heat transfer body P, the heat transfer promotion body can be a corrugated plate shape. Moreover, metals, such as aluminum, copper, stainless steel, iron-plated steel, are mentioned as a heat conductive material which comprises a heat-transfer promoter.

  The heat transfer body P2 is a heat transfer body joined to the heat transfer body P1 in the upper part in the vertical direction. Similar to the heat transfer body P1, the heat transfer body P2 also has a plurality of first flow paths FP1 and second flow paths FP2, and the first flow path FP1 and the second flow path FP2 are along the X-axis direction. And are alternately arranged in parallel via the wall portion P2a. However, the first flow path FP1 and the second flow path FP2 of the heat transfer body P2 are extended in the X-axis direction with respect to the positions of the first flow path FP1 and the second flow path FP2 of the heat transfer body P1. Are shifted in the Y-axis direction perpendicular to the Z-axis direction as the joining direction. Therefore, the heat transfer body P2 has two first flow paths FP1 and three second flow paths FP2.

  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. Moreover, 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 every other heat transfer body P.

  The lid 140 is a flat plate member that is installed on the top of the heat transfer body P1 in the vertical direction. And as shown in FIG. 1, the heat exchange as a joined body or a laminated body is carried out by joining each heat transfer body P and the lid body 140 in order from the heat transfer body P6 in the vertical direction with the flat plate surface horizontal. Part 101 is formed. When the heat exchange unit 101 is assembled, each member is fixed by using a joining method such as TIG (Tungsten Inert Gas) welding or diffusion joining, so that transmission due to poor contact between the members is transmitted. Deterioration of thermal properties is suppressed.

  Here, each of the first flow paths 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, each of the second flow paths FP2 is formed inside the heat transfer body P, and thus does not have an opening that is directly open to the outside of the heat exchange unit 101. Therefore, each of the heat transfer bodies P communicates with one end portion of the second flow path FP2, and the first communication path FP3 provided along the joining direction of the heat transfer body P and the lid 140, and the second flow A second communication path FP4 is provided which communicates with the other end of the path FP2 and is provided along the joining direction.

  Specifically, as shown to Fig.2 (a), 1st communicating path FP3 currently formed in the heat exchanger P1-heat exchanger P5 has penetrated in the joining direction, respectively. And only the 1st communicating path FP3 formed in the heat exchanger P6 located in the lowest part of the heat exchange part 101 does not penetrate so that the 2nd fluid may not be discharged | emitted from the bottom part of the heat exchange part 101. FIG. Further, the first communication passages FP3 formed in the respective heat transfer bodies P are in communication with each other in a state where the respective heat transfer bodies P are joined as the heat exchanging portion 101. That is, the combined first communication path FP3 is opened to the outside through one opening on the upper surface of the heat transfer body P1. The second communication path FP4 has the same shape as the first communication path FP3.

  As a heat conductive material of each element constituting the heat exchange unit 101, a heat resistant metal such as an iron-based alloy or a nickel alloy is suitable. Specifically, heat-resistant alloys such as iron alloys such as stainless steel, nickel alloys such as Inconel 625 (registered trademark), Inconel 617 (registered trademark), Haynes 230 (registered trademark), and the like can be given. These thermally conductive materials are preferable because they have durability or corrosion resistance to the combustion gas that can be used as a reaction progress and a heat medium in the first flow path FP1, but are not limited thereto. Further, it may be iron-plated steel, metal coated with a heat-resistant resin such as fluororesin, or carbon graphite.

  The heat exchanging unit 101 can also be configured 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 numbers of the first flow paths FP1 and the second flow paths FP2 formed in one heat transfer body P are not particularly limited, and the design conditions and heat transfer efficiency of the heat exchange unit 101 are taken into consideration. It can be changed as appropriate. Furthermore, in this embodiment, although the heat exchange part 101 itself is positioned as the main body part of the reaction apparatus 1, in order to suppress heat dissipation from the heat exchange part 101 and suppress heat loss, heat exchange is performed with a housing or a heat insulating material. It is good also as a structure which covers the circumference | surroundings of the part 101. FIG.

  The reaction fluid introduction unit 120 is a housing curved in a concave shape, covers the side surface of the heat exchange unit 101 on the side where the plurality of first flow paths FP1 are opened on the upstream side, and is between the heat exchange unit 101 Create a space. The reaction fluid introduction unit 120 is detachably installed on the heat exchange unit 101 or can be opened and closed.

In addition, the reaction fluid introduction unit 120 includes an introduction pipe 120 a that introduces the reaction fluid from the outside to the inside of the heat exchange unit 101. As shown in FIG. 1, the introduction pipe 120 a is located at the center, specifically the center on the YZ plane, with respect to the side surface of the heat exchange unit 101, and in the same direction as the opening direction of the plurality of first flow paths FP <b> 1. It is connected. Thereby, the introduction pipe 120a can distribute the reaction fluid to each of the first flow paths FP1 in a well-balanced manner.

  Similar to the reaction fluid introduction unit 120, the product discharge unit 122 is a housing curved in a concave shape and covers the side surface of the heat exchange unit 101 on the side where the plurality of first flow paths FP1 are opened on the downstream side. A space is formed with the heat exchange unit 101. The product discharger 122 may be installed so as to be attachable / detachable or openable / closable with respect to the heat exchanging part 101 like the reaction fluid introducing part 120, but the reaction fluid introducing part 120 is configured to be attachable / detachable. If it is, it may be impossible to attach or detach. On the contrary, if the product discharge part 122 is configured to be detachable, the reaction fluid introduction part 120 may be detachable. Moreover, the product discharge part 122 has the discharge piping 122a which discharges | emits a product from the inside of the heat exchange part 101 to the exterior. As shown in FIG. 1, the discharge pipe 122a is also located at the center of the side surface of the heat exchange unit 101, specifically, at the center on the YZ plane, and in the same direction as the opening direction of the plurality of first flow paths FP1. It is connected. As a result, the discharge pipe 122a can discharge the product from each of the first flow paths FP1 while efficiently collecting the product.

  The heat medium introducing section 130 is a plurality of openings formed in the lid body 140 and communicates with the plurality of second communication paths FP4 opened from the upper surface of the heat transfer body P1. Although not shown, the heat medium introduction unit 130 is connected to an introduction pipe for introducing the heat medium from the outside of the heat exchange unit 101.

  The heat medium discharge portion 132 is a plurality of openings formed in the lid body 140 and communicates with the plurality of first communication paths FP3 opened from the upper surface of the heat transfer body P1. Although not shown, the heat medium discharge unit 132 is connected to a discharge pipe that discharges the heat medium to the outside of the heat exchange unit 101.

  The heat exchanging unit 101 can be used as any of a liquid-liquid type heat exchanger, a gas-gas type heat exchanger, and a gas-liquid type heat exchanger, and the reaction fluid and heat medium supplied to the reaction apparatus 1 are Any of gas and liquid may be used.

  In the reaction apparatus 1, a material such as a raw material involved in the chemical reaction as described above is used as a reactant, and a fluid including the reactant is used as a reaction fluid. While the reaction fluid flows through the first flow path FP1, the reaction proceeds by receiving heat or cold from the heat medium flowing through the second flow path FP2, and the reaction proceeds to convert the reactant into a target product. Is done. The reaction fluid may contain a carrier that does not participate in the reaction. The carrier can be appropriately selected from substances that do not affect the progress of the reaction in consideration of the chemical reaction to be performed. In particular, examples of the carrier that can be used for the gaseous reaction fluid include gas carriers such as an inert gas and a low-reactive gaseous substance. On the other hand, as the heat medium, a fluid substance that does not corrode the constituent materials of the reaction apparatus 1 is suitable. For example, a liquid substance such as water or oil, or a gaseous substance such as combustion gas can be used. The configuration using a gaseous substance as the heat medium is easy to handle as compared with the case where a liquid medium is used.

The catalyst contained in the catalyst body has an active metal effective as a main component for promoting the progress of the chemical reaction as described above as a main component, and a catalyst suitable for promoting the reaction is appropriately selected based on the synthesis reaction performed in the reaction apparatus 1. The Examples of the active metal that is a catalyst component include Ni (nickel), Co (cobalt), Fe (iron), Pt (platinum), Ru (ruthenium), Rh (rhodium), Pd (palladium), and the like. As long as it is effective for promoting one kind of reaction or reaction, a plurality of kinds may be used in combination. The catalyst body is prepared, for example, by supporting the catalyst on a structural material. The structural material is selected from heat-resistant metals that can be molded and can carry a catalyst. In order to increase the contact area with the reaction fluid, the structure body, that is, the catalyst body may have a corrugated plate shape whose cross section is curved in a wavy shape or a serrated shape. Examples of heat-resistant metals include Fe (iron), Cr (chromium), Al (aluminum), Y (yttrium), Co (cobalt), Ni (nickel), Mg (magnesium), Ti (titanium), and Mo (molybdenum). ), W (tungsten), Nb (niobium), Ta (tantalum) and the like, and there are heat-resistant alloys mainly composed of one or more kinds of metals. For example, the catalyst body may be configured by molding a thin plate-shaped structural material made of a heat-resistant alloy such as Fecralloy (registered trademark). The catalyst loading method includes a method of directly loading on a structural material by surface modification or the like, and a method of indirectly loading using a carrier. In practical terms, it is easy to carry a catalyst using a carrier. is there. In consideration of the reaction to be carried out in the reaction apparatus 1, the support is appropriately selected from materials that do not hinder the progress of the reaction and have durability and that can favorably support the catalyst to be used.

Examples of the supporting method using the carrier include a method of forming a mixture layer of the catalyst and the carrier on the surface of the formed structural material, and a method of supporting the catalyst by surface modification after forming the carrier layer. .

  Next, the operation and effect of this embodiment will be described.

  First, in the heat treatment apparatus using heat exchange between the first fluid and the second fluid, the first flow path FP1 for circulating the first fluid and the second flow path FP2 for circulating the second fluid are interposed through the wall portion. The first heat transfer body arranged in parallel, the first flow path FP1 through which the first fluid flows, and the second flow path FP2 through which the second fluid flows are arranged in parallel through the wall portion, A second heat transfer body joined to the heat transfer body, and at least a part of the first flow path FP1 included in the second heat transfer body is at least one of the second flow paths FP2 included in the first heat transfer body. It overlaps with the part in the joining direction and without contact.

  However, the heat treatment apparatus corresponds to the reaction apparatus 1 in this embodiment. The first fluid may be a reaction fluid or product, and the second fluid may be a heat medium. In addition, 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. 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 in 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 encompass 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 joined in the joining direction and in a non-contact manner. The case of overlapping is also included.

  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 in parallel via the side wall portion. That is, the first flow path FP1 can receive heat from the left-right direction in the drawing which is perpendicular to the extending direction and the joining direction. Second, the first flow path FP1 receives heat from the second flow path FP2 of the other heat transfer body P joined 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 upper and lower diagonal directions in the drawing. Therefore, the heat transfer area can be increased as compared with the conventional heat treatment apparatus in which the reaction channel 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 do.

  In the heat treatment apparatus according to the present embodiment, at least a part of the first flow path FP1 included in the second heat transfer body is further bonded to at least a part of the first flow path FP1 included in the first heat transfer body. Overlapping in direction and non-contact.

  According to the heat treatment apparatus according to the present embodiment, the first flow path FP1 of the second heat transfer body eventually results in the first flow path FP1 of the first heat transfer body and the first flow path FP1 as shown in FIGS. A part overlaps both of the second flow paths FP2. Therefore, from the viewpoint of increasing the heat transfer area than before, the viewpoint of reducing the lateral 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 juxtaposed, as much as possible. When both are considered, the most efficient.

  Further, in the heat treatment apparatus according to the present embodiment, the ratio x in which the first flow path FP1 included in the second heat transfer body and the second flow path FP2 included in the first heat transfer body overlap is determined by the first flow path FP1 and the first flow path FP1. When the channel height in the joining direction of the second channel FP2 is H and the channel widths of the first channel FP1 and the second channel FP2 are W, the condition x> 1- (H / W) is satisfied. Fulfill.

  According to the heat treatment apparatus according to the present embodiment, it is possible to reduce the number of installed heat transfer bodies P constituting 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, 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 are considered. .

  Here, in the flow path arrangement in the present embodiment, the first flow path FP1 receives heat from the second flow path FP2 that is present in the upper, lower, left, and right directions in the extending direction, so the heat transfer area is (2 × H). + (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 described above, the reaction flow path heats only from the heat medium flow path that exists above and below in the extending direction. Since it is not received, 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 over the conventional flow path arrangement, (2 × H) + (2 × xW)> (2 × W) That is, the ratio x should 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 installed heat transfer bodies P is reduced to about half, while the heat transfer area is equal or improved as compared with the conventional heat exchange section. Can be reduced.

  Furthermore, 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 included in the first heat transfer body and the second flow path FP2 included in the second heat transfer body. Communication passages FP3 and FP4.

  According to the heat treatment apparatus according to the present embodiment, the first communication path FP3 and the second communication path FP4 are provided in the first heat transfer body and the second heat transfer body, and a plurality of the heat transfer units 101 are present. The second flow path FP2 is communicated with the outside. Therefore, first, since the first communication path FP3 and the second communication path FP4 are present inside the heat exchange unit 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 casing, or the like serving as a communication path to the side surface of the heat exchange unit 101, the apparatus configuration is simplified, and the first communication path FP3 and the second communication path are also simplified. The formation of the FP4 also has the advantage of being simplified because it merely opens a hole.

(Other embodiments)
Note that, as described 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 in the joining direction and in a non-contacting manner. May overlap. 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 FP3 is not displaced until 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 overlapped in the joining direction. And the 2nd communicating path FP4 can be formed in linear form, as shown to Fig.2 (a). It is easy for the first communication path FP3 and the second communication path FP4 to be straight when forming the first communication path FP3 and the second communication path FP4. On the other hand, in the configuration as 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 are completely overlapped in the joining direction. For example, the first communication path FP3 is configured by combining a communication path FP3a communicating with the second flow path FP2 and a communication path FP3b inclined with respect to the joining direction. The same applies to the second communication path FP4. In this case, the process of forming the first communication path FP3 and the second communication path FP4 is complicated as compared with the above embodiment, but it is advantageous in that the heat transfer area is further increased.

  The first fluid and the second fluid may be different materials or the same material depending on the heat treatment apparatus to which the present invention is applied. Moreover, in the said embodiment, although the 1st fluid was a reaction fluid or a product, and the 2nd fluid was a heat carrier, it is also possible to make it the other way around. Furthermore, 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 a heat medium.

  Moreover, in the said embodiment, it penetrates in a straight line from the wall surface of the two types of shape provided in parallel for every heat exchanger P, ie, the wall surface of the one end part of the heat exchanger P to the wall surface of the other end part. The first flow path FP1 and the second flow path FP2 whose side surfaces are surrounded by the 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 shapes as described above. 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 portion of the heat transfer body P as in the illustration of the first flow path FP1. The other end may be connected to the communication path in the same manner as illustrated in the second flow path FP2.

  Moreover, in the said embodiment, the heat exchange part 101 is a counterflow type with which the 1st fluid which distribute | circulates 1st flow path FP1 and the 2nd fluid which distribute | circulates 2nd flow path FP2 flow in the mutually opposite direction. However, it may be a parallel flow type that flows in the same direction. Furthermore, in the present invention, the direction in which the first fluid and the second fluid flow is not limited at all.

  Furthermore, in the said embodiment, although the six heat exchangers P which comprise the heat exchange part 101 shall be joined, ie, laminated | stacked in the perpendicular direction, this invention is not limited to this.
