　また、筐体５０１は、化学蓄熱材３の反応による膨張と収縮の繰り返しによって生じる押しつぶし圧力５０５を受けることになる。筐体５０１に充填された拡散部材５０６は、拡散部材５０６の間を反応気体７が蛇行するように拡散する目的で充填されるほかに、押しつぶし圧力５０５により押しつぶされにくくするための役割も果たす。 Furthermore, the casing 501 is subjected to crushing pressure 505 caused by repeated expansion and contraction due to the reaction of the chemical heat storage material 3. The diffusion members 506 filled in the housing 501 are used for the purpose of diffusing the reaction gas 7 in a meandering manner between the diffusion members 506, and also serve to prevent the reaction gas 7 from being crushed by the crushing pressure 505.
　また、拡散部材５０６が内部に充填された筐体からなるものとしては、反応気体７の流路（通過する空間）を確保でき、かつ、押しつぶし圧力５０５に耐えることのできる別の部材の物体が、拡散部材５０６として筐体５０１の内部に充填されたものが例示できる。具体的には、金属もしくは砕石やセラミックスなどの無機材料の他、潜熱蓄熱の役割を果たすＰＣＭカプセルを拡散部材５０６に用いてもよい。 In addition, as a case made of a case in which the diffusion member 506 is filled, an object made of another member that can secure a flow path (passage space) for the reaction gas 7 and can withstand the crushing pressure 505 is used. An example of the diffusion member 506 is one filled inside the housing 501. Specifically, in addition to inorganic materials such as metal, crushed stone, and ceramics, a PCM capsule that plays a role of storing latent heat may be used for the diffusion member 506.
　ＰＣＭカプセルとは、潜熱蓄熱材（ＰＣＭは、Ｐｈａｓｅ　Ｃｈａｎｇｅ　Ｍａｔｅｒｉａｌの略称）を金属カプセルに封入したものであり、潜熱蓄熱材が融解と凝固を繰り返すことで、熱の吸収と放出を行うものである。ＰＣＭカプセルは、高温になると中の潜熱蓄熱材は溶けて液体となるが、外側の金属カプセルは固体の状態であることから、潜熱蓄熱材が漏れることなく、また、押しつぶし圧力５０５が生じても、反応気体７の流路を確保することができる。 A PCM capsule is a metal capsule containing a latent heat storage material (PCM is an abbreviation for Phase Change Material), and the latent heat storage material absorbs and releases heat by repeating melting and solidification. . When the PCM capsule reaches a high temperature, the latent heat storage material inside melts and becomes liquid, but since the outer metal capsule is in a solid state, the latent heat storage material does not leak, and even if crushing pressure 505 is generated. , a flow path for the reaction gas 7 can be secured.
　また、多孔体としては、小さな空間を多量に有する金属のセル状の構造物であり、気泡が互いにつながった連続気泡体の発泡金属と呼ばれるものを使用することができる。 Furthermore, as the porous body, it is possible to use what is called a metal foam, which is a metal cell-like structure having a large amount of small spaces, and has open cells in which the cells are connected to each other.
　さらに、他の多孔体としては、図４に示すように、板状部材２０２ａ（図４（Ａ）図）及び２０２ｂ（図４（Ｂ）図）の板厚方向に複数の貫通孔２０３ａ及び２０３ｂが設けられ、板状部材２０２ａ及び２０２ｂの貫通孔２０３ａ及び２０３ｂ同士が互いに位置をずらされて重ね合わされた板状体２０１（図４（Ｃ）図）が該当する。 Furthermore, as other porous bodies, as shown in FIG. This corresponds to the plate-like body 201 (FIG. 4C) in which the through-holes 203a and 203b of the plate-like members 202a and 202b are shifted from each other and overlapped.
　また、図５に示すように、板状体２０１が容器２の内壁に接触するように配置された部分の断面（図４（Ｃ）図のＢ-Ｂ断面）を示して説明すると、板状部材２０２ａ及び２０２ｂは、貫通孔２０３ａ及び２０３ｂ同士が互いに位置をずらされて重ね合わされた状態であることから、空間２１に露出した部分の貫通孔２０３ａから反応気体７が侵入し、反応気体７が貫通孔２０３ａ及び２０３ｂを蛇行するように下方に移動する。よって、下方の化学蓄熱材３にも反応気体７を供給することが可能である。
　また、反応気体供給体５として、板状体２０１を使用した場合、重ね合わせ部分２０５が存在することから、押しつぶし圧力５０５を受けたとしても潰されることがない効果がある。 In addition, as shown in FIG. 5, the plate-shaped body 201 is shown in a cross section (B-B cross-section in FIG. In the members 202a and 202b, since the through holes 203a and 203b are overlapped with each other with their positions shifted, the reactive gas 7 enters from the through hole 203a in the portion exposed to the space 21, and the reactive gas 7 It moves downward in a meandering manner through the through holes 203a and 203b. Therefore, it is possible to supply the reaction gas 7 also to the chemical heat storage material 3 below.
Further, when the plate-shaped body 201 is used as the reaction gas supply body 5, since the overlapping portion 205 exists, there is an effect that it will not be crushed even if it is subjected to the crushing pressure 505.
［カートリッジ式化学蓄熱反応器の使用方法について］
　次に、図６を参照し、本実施態様に係るカートリッジ式化学蓄熱反応器１ａの使用方法について説明する。 [How to use the cartridge type chemical thermal storage reactor]
Next, with reference to FIG. 6, a method of using the cartridge type chemical heat storage reactor 1a according to this embodiment will be described.
　まず、蓄熱反応を行う場合（化学蓄熱方法）を例に説明する。まず、反応媒体連結部２３と熱交換連結部４３とが連結されていない携帯可能な状態において、カートリッジ式化学蓄熱反応器１ａが、加熱源１２に運搬される。この工程を蓄熱準備工程とする。
　なお、ここでいう加熱源１２は、使用後の加熱炉などを想定しており、使用後であっても加熱炉内は高温雰囲気下となっている。このため、使用後の加熱炉の空いたスペースにカートリッジ式化学蓄熱反応器１ａを設置するだけで化学蓄熱を行うことができる。 First, a case where a heat storage reaction is performed (chemical heat storage method) will be explained as an example. First, the cartridge type chemical thermal storage reactor 1a is transported to the heat source 12 in a portable state in which the reaction medium connection part 23 and the heat exchange connection part 43 are not connected. This process is referred to as a heat storage preparation process.
Note that the heating source 12 here is assumed to be a heating furnace after use, and even after use, the inside of the heating furnace is under a high-temperature atmosphere. Therefore, chemical heat storage can be performed simply by installing the cartridge type chemical heat storage reactor 1a in the vacant space of the heating furnace after use.
　次に、カートリッジ式化学蓄熱反応器１ａが、反応媒体通過口２２を開栓した状態で加熱源１２に配置される。この工程を蓄熱工程とする。
　蓄熱工程が行われることにより、化学蓄熱材３の生成した生成気体８が、反応気体供給体５の流路と、反応媒体通過口２２を経由して外部に排出される。 Next, the cartridge type chemical heat storage reactor 1a is placed in the heat source 12 with the reaction medium passage port 22 opened. This process is called a heat storage process.
By performing the heat storage step, the generated gas 8 generated by the chemical heat storage material 3 is discharged to the outside via the flow path of the reaction gas supply body 5 and the reaction medium passage port 22.
　次に、蓄熱工程が完了した後、カートリッジ式化学蓄熱反応器１ａが、加熱された後に反応媒体通過口２２に蓋がされる。この工程を閉栓工程とする。 Next, after the heat storage step is completed, the reaction medium passage port 22 is covered with a lid after the cartridge type chemical heat storage reactor 1a is heated. This process is called a capping process.
　次に、発熱反応を行う場合（化学発熱方法）の場合について説明する。カートリッジ式化学蓄熱反応器１ａが使用される場所に運搬され、反応媒体連結部２３が、反応気体７を供給する蒸発器と連結され、さらに、熱交換連結部４３が、カートリッジ式化学蓄熱反応器１ａの発熱反応の熱を受け取る供給先と連結される。この工程を発熱準備工程とする。 Next, a case where an exothermic reaction is performed (chemical exothermic method) will be explained. The cartridge-type chemico-thermal storage reactor 1a is transported to a place where it is used, the reaction medium connection part 23 is connected to the evaporator that supplies the reaction gas 7, and the heat exchange connection part 43 is further connected to the cartridge-type chemico-thermal storage reactor 1a. It is connected to a supply destination that receives the heat of the exothermic reaction of 1a. This step is referred to as a heat generation preparation step.
　次に、反応気体７がカートリッジ式化学蓄熱反応器１ａに供給され、熱交換部４を介してカートリッジ式化学蓄熱反応器１ａの外部に熱が供給される。この工程を発熱工程とする。 Next, the reaction gas 7 is supplied to the cartridge type chemical heat storage reactor 1a, and heat is supplied to the outside of the cartridge type chemical heat storage reactor 1a via the heat exchange section 4. This process is referred to as a heat generation process.
　発熱工程完了後、反応媒体連結部２３が、蒸発器との連結が解除され、さらに、熱交換連結部４３が、熱を供給する供給先との連結が解除される。この工程を携帯準備工程とする。
　携帯準備工程後、蓄熱準備工程が行われ、繰り返し化学蓄熱方法と化学発熱方法を行うことができる。
　なお、カートリッジ式化学蓄熱反応器１ａは、携帯可能であることから、異なる場所の加熱源１２に運搬することができ、加熱源１２に容易に設置できるため利便性に優れる。 After the exothermic step is completed, the reaction medium connection section 23 is disconnected from the evaporator, and furthermore, the heat exchange connection section 43 is disconnected from the heat supply destination. This process is called a mobile preparation process.
After the carrying preparation process, a heat storage preparation process is performed, and the chemical heat storage method and the chemical heat generation method can be repeatedly performed.
The cartridge type chemical heat storage reactor 1a is portable, so it can be transported to the heating source 12 at a different location, and it can be easily installed in the heating source 12, so it is highly convenient.
　本実施の態様では、蓄熱工程において、反応媒体通過口２２が開栓した状態のカートリッジ式化学蓄熱反応器１ａを加熱源１２に配置した。しかしながら、加熱源１２によっては、生成気体８が加熱源１２である設備を劣化させるまたは設備の故障の原因となる虞がある場合もあり、生成気体８が加熱源１２に放出されることが好ましくない場合もある。かかる場合には、蓄熱工程の前に、生成気体８を加熱源１２の外部に誘導し放出するための携帯可能かつ着脱可能な管を反応媒体連結部２３と連結させた後に蓄熱工程を行うようにしてもよい。 In this embodiment, in the heat storage step, the cartridge type chemical thermal storage reactor 1a with the reaction medium passage port 22 opened was placed in the heat source 12. However, depending on the heating source 12, there is a possibility that the generated gas 8 may deteriorate the equipment that is the heating source 12 or cause the equipment to malfunction, so it is preferable that the generated gas 8 is released to the heating source 12. Sometimes there isn't. In such a case, before the heat storage step, a portable and detachable tube for guiding and releasing the generated gas 8 to the outside of the heating source 12 is connected to the reaction medium connection part 23, and then the heat storage step is performed. You can also do this.
　本発明の実施態様の変形例として、図７に示すように、カートリッジ式化学蓄熱反応器１ａの外面に着脱可能な断熱材６を設置することができるようにしてもよい。カートリッジ式化学蓄熱反応器１ａが、加熱源１２に投入される場合（蓄熱反応時）は、断熱材６を撤去した状態とし、発熱する場合（発熱反応時）は、断熱材６を設置した状態とすることで効率のよい蓄熱及び放熱を行うことができる。 As a modification of the embodiment of the present invention, as shown in FIG. 7, a removable heat insulating material 6 may be installed on the outer surface of the cartridge type chemical heat storage reactor 1a. When the cartridge type chemical heat storage reactor 1a is put into the heat source 12 (during a heat storage reaction), the heat insulating material 6 is removed, and when heat is generated (during an exothermic reaction), the heat insulating material 6 is installed. By doing so, efficient heat storage and heat radiation can be performed.
　上記本発明の実施態様の変形例のカートリッジ式化学蓄熱反応器１ａの使用方法としては、蓄熱工程の前に、断熱材６を撤去する断熱材撤去工程と、発熱工程の前に断熱材６を設置する断熱材設置工程と、を含んでもよい。 The method of using the cartridge-type chemical heat storage reactor 1a according to the modified example of the embodiment of the present invention includes a heat insulating material removal step of removing the heat insulating material 6 before the heat storage step, and a heat insulating material removing step of removing the heat insulating material 6 before the heat generation step. and a step of installing a heat insulating material.
〔第２の実施態様〕
［カートリッジ式化学蓄熱反応器連結体］
　次に図８を参照し、本発明の第２の実施態様のカートリッジ式化学蓄熱反応器連結体１０について説明する。なお、カートリッジ式化学蓄熱反応器１ａと同じ構成のものについては、同じ符号を付し、説明を省略する。
　本実施態様のカートリッジ式化学蓄熱反応器連結体１０は、本発明の第１の実施態様のカートリッジ式化学蓄熱反応器１ａを複数備え、複数のカートリッジ式化学蓄熱反応器１ａの熱交換部４同士を連結する熱交換配管連結具１１を備えたことが、本発明の第１の実施態様と異なる。 [Second embodiment]
[Cartridge type chemical heat storage reactor connection body]
Next, referring to FIG. 8, a cartridge type chemical thermal storage reactor connector 10 according to a second embodiment of the present invention will be described. Components having the same configuration as the cartridge-type chemical heat storage reactor 1a are given the same reference numerals, and explanations thereof will be omitted.
The cartridge-type chemico-thermal storage reactor assembly 10 of this embodiment includes a plurality of cartridge-type chemico-thermal storage reactors 1a of the first embodiment of the present invention, and the heat exchange parts 4 of the plurality of cartridge-type chemico-thermal storage reactors 1a are connected to each other. This embodiment differs from the first embodiment of the present invention in that it includes a heat exchange piping connector 11 that connects the two.
　カートリッジ式化学蓄熱反応器連結体１０は、本発明の第１の実施態様のカートリッジ式化学蓄熱反応器１ａを複数備える。これらのカートリッジ式化学蓄熱反応器１ａの数は、３つの場合を例示したが、２つ、４つ、５つ以上であってもよい。
　カートリッジ式化学蓄熱反応器１ａを複数備えることから、様々な場所で蓄熱をしたカートリッジ式化学蓄熱反応器１ａを一つのカートリッジ式化学蓄熱反応器連結体１０とし、発熱を行うことで、様々な箇所の熱源を一つにまとめて再利用することができ、連結する数を調整することで発熱量の調整を行うことができる効果がある。
　なお、複数のカートリッジ式化学蓄熱反応器１ａが互いに密着した状態で連結できることが好ましい。この構造であれば、発熱反応時の熱損失を少なくできる点で好ましい。 The cartridge-type chemico-thermal storage reactor assembly 10 includes a plurality of cartridge-type chemico-thermal storage reactors 1a according to the first embodiment of the present invention. The number of these cartridge-type chemical heat storage reactors 1a is three, but the number may be two, four, five or more.

The heat sources can be reused together, and the amount of heat generated can be adjusted by adjusting the number of connections.
Note that it is preferable that the plurality of cartridge type chemical heat storage reactors 1a can be connected in close contact with each other. This structure is preferable in that heat loss during exothermic reaction can be reduced.
　また、図９に示すように、カートリッジ式化学蓄熱反応器連結体１０は、カートリッジ式化学蓄熱反応器１ａと形状が異なるカートリッジ式化学蓄熱反応器１ｂを有してもよい。カートリッジ式化学蓄熱反応器１ｂは、カートリッジ式化学蓄熱反応器１ａと同じ機能、構造を有しており、容器２の形状と化学蓄熱材３の容量が異なる。
　カートリッジ式化学蓄熱反応器１ａとカートリッジ式化学蓄熱反応器１ｂの形状が異なる場合であっても、熱交換配管連結具１１でカートリッジ式化学蓄熱反応器連結体１０として連結することが可能である。
　加熱源１２は使用済みの加熱炉等にカートリッジ式化学蓄熱反応器１ａを投入するだけで蓄熱ができるメリットがあるが、加熱炉の形状や大きさ、加熱炉の使い方によってはカートリッジ式化学蓄熱反応器１ａが炉に適切に入らなかったりする可能性がある。そこで、容器２の形状や化学蓄熱材３の容量を異ならせることで、加熱炉の形状や大きさ、加熱炉の使い方に関わらずカートリッジ式化学蓄熱反応器１ａを蓄熱することができる。 Further, as shown in FIG. 9, the cartridge-type chemico-thermal storage reactor assembly 10 may include a cartridge-type chemico-thermal storage reactor 1b having a different shape from the cartridge-type chemico-thermal storage reactor 1a. The cartridge type chemical heat storage reactor 1b has the same function and structure as the cartridge type chemical heat storage reactor 1a, but differs in the shape of the container 2 and the capacity of the chemical heat storage material 3.
Even if the cartridge type chemical heat storage reactor 1a and the cartridge type chemical heat storage reactor 1b have different shapes, it is possible to connect them as the cartridge type chemical heat storage reactor connector 10 using the heat exchange piping connector 11.
The heating source 12 has the advantage of being able to store heat simply by putting the cartridge-type chemical heat storage reactor 1a into a used heating furnace, etc., but depending on the shape and size of the heating furnace and how the heating furnace is used, the cartridge-type chemical heat storage reaction There is a possibility that the vessel 1a may not fit properly into the furnace. Therefore, by varying the shape of the container 2 and the capacity of the chemical heat storage material 3, it is possible to store heat in the cartridge type chemical heat storage reactor 1a regardless of the shape and size of the heating furnace or how the heating furnace is used.
（熱交換配管連結具）
　熱交換配管連結具１１は、複数のカートリッジ式化学蓄熱反応器１ａのうちの一方のカートリッジ式化学蓄熱反応器１ａの熱交換連結部４３と他方のカートリッジ式化学蓄熱反応器１ａの熱交換連結部４３とを連結し、熱交換媒体の流れる一つの流路とするための部材である。
　熱交換配管連結具１１の大きさ、材質は特に限定されない。熱交換配管連結具１１の両端には、熱交換連結部４３と連結可能な被連結部１１１を備える。熱交換連結部４３と被連結部１１１との連結は、熱交換媒体が外部に漏れない構造であれば特に限定されない。 (Heat exchange piping connector)
The heat exchange piping connector 11 connects the heat exchange connection part 43 of one cartridge type chemical heat storage reactor 1a of the plurality of cartridge type chemical heat storage reactors 1a and the heat exchange connection part of the other cartridge type chemical heat storage reactor 1a. 43 to form one flow path through which the heat exchange medium flows.
The size and material of the heat exchange piping connector 11 are not particularly limited. Both ends of the heat exchange piping connector 11 are provided with connected parts 111 that can be connected to the heat exchange connector 43 . The connection between the heat exchange connecting part 43 and the connected part 111 is not particularly limited as long as the structure prevents the heat exchange medium from leaking to the outside.

Heat is stored in each of the cartridge type chemical thermal storage reactors 1a using heating sources 12a, 12b, and 12c located at various locations.
　次に、発熱反応を行う場合（化学発熱方法）の場合について説明する。複数のカートリッジ式化学蓄熱反応器１ａが使用される場所に運搬され、熱交換配管連結具１１を用いて、複数のカートリッジ式化学蓄熱反応器１ａが互いに連結されることにより、カートリッジ式化学蓄熱反応器連結体１０が完成する。この工程を連結工程とする。 Next, a case where an exothermic reaction is performed (chemical exothermic method) will be explained.
