Description

本発明は、樹脂複合化水素吸蔵合金を容器に充填する方法に関する。 The present invention relates to a method for filling a container with a resin composite hydrogen storage alloy.

水素を貯蔵する方法として、容器に充填された水素吸蔵合金に、水素ガスを吸収させて水素を貯蔵する方法がある。この方法は、水素ガスをガスボンベに高圧貯蔵する方法などに比べて、安全性、および体積充填効率に優れるため、現在注目されている。 As a method of storing hydrogen, there is a method of absorbing hydrogen gas in a hydrogen storage alloy filled in a container to store hydrogen. This method is currently attracting attention because it is superior in safety and volume filling efficiency as compared with a method of storing hydrogen gas in a gas cylinder at high pressure.

一方、水素吸蔵合金は、水素ガスの吸収・放出にともなって、最大３０％膨張・収縮するため、その際に生じる応力が容器に歪みを与え、容器の耐久性に悪影響を及ぼす。水素吸蔵合金が膨張・収縮することで容器へ作用する応力を緩和する方法として、水素吸蔵合金と樹脂とを混合して樹脂複合化水素吸蔵合金とし、この樹脂複合化水素吸蔵合金を、容器に充填する方法がある。 On the other hand, since the hydrogen storage alloy expands and contracts by up to 30% with the absorption and release of hydrogen gas, the stress generated at that time distorts the container and adversely affects the durability of the container. As a method of relieving the stress acting on the container due to the expansion and contraction of the hydrogen storage alloy, the hydrogen storage alloy and the resin are mixed to form a resin composite hydrogen storage alloy, and this resin composite hydrogen storage alloy is used in the container. There is a filling method.

ここで、特許文献１には、水素吸蔵合金と樹脂とカーボンファイバーとを混合してなる樹脂複合材を容器に充填する方法が記載されている。特許文献１では、上記樹脂複合材を容器に充填する際に、所定周波数の振動を容器に継続的に与えている。これにより、水素吸蔵合金を所望の充填率で容器内に充填することができるとのことである。 Here, Patent Document 1 describes a method of filling a container with a resin composite material obtained by mixing a hydrogen storage alloy, a resin, and carbon fiber. In Patent Document 1, when the resin composite material is filled in a container, vibration of a predetermined frequency is continuously applied to the container. As a result, the hydrogen storage alloy can be filled in the container at a desired filling rate.

なお、水素吸蔵合金を容器に充填する方法として、特許文献２に記載の方法もある。特許文献２には、ベルトコンベヤで容器を移送しながら、水素吸蔵合金を連続的に容器に充填する方法が記載されている。 As a method of filling a container with a hydrogen storage alloy, there is also a method described in Patent Document 2. Patent Document 2 describes a method of continuously filling a container with a hydrogen storage alloy while transferring the container by a belt conveyor.

ここで、水素ガスが水素吸蔵合金に吸収される水素吸蔵反応は、発熱反応であるため、水素吸蔵合金が充填された容器に水素ガスを充填する際には、容器を迅速に冷却する必要がある。そのため、水素吸蔵合金が充填される容器は、熱交換機能を内部に有する容器である必要がある。 Here, since the hydrogen storage reaction in which hydrogen gas is absorbed by the hydrogen storage alloy is an exothermic reaction, it is necessary to quickly cool the container when filling the container filled with the hydrogen storage alloy with hydrogen gas. be. Therefore, the container filled with the hydrogen storage alloy needs to be a container having a heat exchange function inside.

熱交換器機能は、例えば、多数のフィン・仕切りなどを容器の内部に設けることで具現化される。一方、水素吸蔵合金と樹脂とを混合してなる樹脂複合化水素吸蔵合金は、流動性が悪く（粘性が高く）、多数のフィン・仕切りなどを内部に有する容器には充填しにくい。特許文献１に記載のように、容器を振動させる程度では、容器内に隙間なく、且つ時間効率良く、樹脂複合化水素吸蔵合金を充填することは難しい。 The heat exchanger function is realized, for example, by providing a large number of fins / partitions inside the container. On the other hand, the resin composite hydrogen storage alloy obtained by mixing a hydrogen storage alloy and a resin has poor fluidity (high viscosity) and is difficult to fill in a container having a large number of fins / partitions inside. As described in Patent Document 1, it is difficult to fill the container with the resin composite hydrogen storage alloy without gaps and with time efficiency by vibrating the container.

本発明は、上記実情に鑑みてなされたものであり、その目的は、水素吸蔵合金と樹脂とを混合してなる樹脂複合化水素吸蔵合金を、熱交換部を内部に有する容器内へ、隙間なく且つ時間効率良く、充填し得る方法を提供することである。 The present invention has been made in view of the above circumstances, and an object of the present invention is to insert a resin composite hydrogen storage alloy, which is a mixture of a hydrogen storage alloy and a resin, into a container having a heat exchange portion inside. It is to provide a method which can be filled without and time-efficiently.

本発明は、複数の板状部が軸方向に並んでなる熱交換部を内部に有する容器への樹脂複合化水素吸蔵合金の充填方法であって、カバーを外した前記容器を軸方向まわりに回転させながら、隣り合う前記板状部の間に前記樹脂複合化水素吸蔵合金を注入していくことを特徴とする。 The present invention is a method for filling a container having a heat exchange portion in which a plurality of plate-shaped portions are arranged in the axial direction with a resin composite hydrogen storage alloy, and the container with the cover removed is placed around the axial direction. It is characterized in that the resin composite hydrogen storage alloy is injected between the adjacent plate-shaped portions while rotating.

本発明の充填方法によると、水素吸蔵合金と樹脂とを混合してなる樹脂複合化水素吸蔵合金を、熱交換部を内部に有する容器内へ、隙間なく且つ時間効率良く、充填し得る。 According to the filling method of the present invention, a resin composite hydrogen storage alloy formed by mixing a hydrogen storage alloy and a resin can be filled into a container having a heat exchange portion inside without gaps and with time efficiency.

以下、本発明を実施するための形態について図面を参照しつつ説明する。 Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.

（容器の構成）
まず、樹脂複合化水素吸蔵合金が充填される容器の一実施形態について、図１を参照しつつ説明する。なお、本発明に係る充填方法は、図１に示す容器１０１や、後述する図３、４に示す容器１０２、１０３に限られることはなく、複数の板状部（フィンや仕切り）が軸方向Ｚに並んでなる熱交換部を内部に有する様々な形態の容器に適用することができる。 (Container configuration)
First, an embodiment of a container filled with a resin composite hydrogen storage alloy will be described with reference to FIG. 1. The filling method according to the present invention is not limited to the container 101 shown in FIG. 1 and the containers 102 and 103 shown in FIGS. 3 and 4 described later, and a plurality of plate-shaped portions (fins and partitions) are axially oriented. It can be applied to various types of containers having heat exchange portions arranged side by side in Z.

図１に示すように、本実施形態の容器１０１は、複数の板状部２ａが軸方向Ｚに並んでなる熱交換部としての螺旋フィン２を内部に有する容器であって、螺旋フィン２が外周面に固定された筒体１と、カバー３とを有する。螺旋フィン２が配置された、筒体１とカバー３との間の空間Ｓは、樹脂複合化水素吸蔵合金が充填される空間である。螺旋フィン２は、複数の板状部２ａが螺旋状に形成されたものである。 As shown in FIG. 1, the container 101 of the present embodiment is a container having a spiral fin 2 as a heat exchange portion in which a plurality of plate-shaped portions 2a are arranged in the axial direction Z, and the spiral fin 2 is a container. It has a cylinder 1 fixed to an outer peripheral surface and a cover 3. The space S between the cylinder 1 and the cover 3 in which the spiral fins 2 are arranged is a space filled with the resin composite hydrogen storage alloy. The spiral fin 2 is formed by forming a plurality of plate-shaped portions 2a into a spiral shape.

ここで、樹脂複合化水素吸蔵合金とは、水素吸蔵合金と、樹脂（合成樹脂）とを混合してなるもののことをいう。例えば、粉末状の水素吸蔵合金に、合成樹脂を添加混合することで、樹脂複合化水素吸蔵合金が作製される。水素吸蔵合金としては、２元系合金、３元系合金、４元系合金、および５元系合金などが挙げられ、様々な種別、組成、結晶構造の水素吸蔵合金が存在するが、本発明に係る充填方法は、特定の水素吸蔵合金への適用に限定されるものではない。 Here, the resin composite hydrogen storage alloy refers to a mixture of a hydrogen storage alloy and a resin (synthetic resin). For example, a resin composite hydrogen storage alloy is produced by adding and mixing a synthetic resin to a powdered hydrogen storage alloy. Examples of the hydrogen storage alloy include binary alloys, ternary alloys, quaternary alloys, and quaternary alloys, and there are various types, compositions, and crystal structures of hydrogen storage alloys. The filling method according to the above is not limited to the application to a specific hydrogen storage alloy.

水素吸蔵合金と混合される合成樹脂としては、例えば、フェノール樹脂、メラミン樹脂、シリコン樹脂、およびポリウレタン樹脂などの熱硬化性樹脂、ならびに、ポリプロピレン樹脂、ポリエチレン樹脂、およびセルロイド樹脂などの熱可塑性樹脂が挙げられる。なお、合成樹脂は、水素吸蔵合金に吸蔵された水素の放出加熱温度よりも高い軟化点（例えば、１００度以上の軟化点）を有する合成樹脂であることが好ましい。 Examples of the synthetic resin mixed with the hydrogen storage alloy include thermosetting resins such as phenol resin, melamine resin, silicon resin, and polyurethane resin, and thermoplastic resins such as polypropylene resin, polyethylene resin, and celluloid resin. Can be mentioned. The synthetic resin is preferably a synthetic resin having a softening point (for example, a softening point of 100 degrees or higher) higher than the release heating temperature of hydrogen stored in the hydrogen storage alloy.

筒体１の中には、熱交換媒体（例えば、水）が流される。樹脂複合化水素吸蔵合金が充填された容器１０１に水素ガスを充填する際、筒体１の中に例えば水を流し、この水により、樹脂複合化水素吸蔵合金は冷却される。樹脂複合化水素吸蔵合金からの熱は、容器１０１内の筒体１の外周面、および螺旋フィン２から、筒体１内を流れる水に移行する。螺旋フィン２（板状部２ａ）、および筒体１は、伝熱性に優れるものがよく、その材料は、例えば、ステンレス鋼、アルミニウム合金、銅合金などである。 A heat exchange medium (for example, water) is flowed through the cylinder 1. When filling the container 101 filled with the resin composite hydrogen storage alloy with hydrogen gas, for example, water is flowed through the cylinder 1, and the water cools the resin composite hydrogen storage alloy. The heat from the resin composite hydrogen storage alloy is transferred from the outer peripheral surface of the cylinder 1 in the container 101 and the spiral fins 2 to the water flowing in the cylinder 1. The spiral fin 2 (plate-shaped portion 2a) and the tubular body 1 are preferably those having excellent heat transfer properties, and the material thereof is, for example, stainless steel, an aluminum alloy, a copper alloy, or the like.

本実施形態のカバー３は、筒状のカバー本体４と、カバー本体４の軸方向両端部を閉止する円板状の２枚のプレート５とで構成される。なお、カバー本体４の軸方向端部のフランジ部４ａとプレート５とは、例えばボルト（不図示）などの固定手段で固定される。また、カバー３（カバー本体４）には、水素ガスの入口・出口が設けられるが、この図示は省略されている。 The cover 3 of the present embodiment is composed of a tubular cover main body 4 and two disk-shaped plates 5 that close both ends of the cover main body 4 in the axial direction. The flange portion 4a at the axial end of the cover body 4 and the plate 5 are fixed by fixing means such as bolts (not shown). Further, the cover 3 (cover main body 4) is provided with an inlet / outlet for hydrogen gas, but this illustration is omitted.

（樹脂複合化水素吸蔵合金の充填方法）
図２を参照しつつ、樹脂複合化水素吸蔵合金を容器１０１に充填する方法について説明する。 (Filling method of resin composite hydrogen storage alloy)
A method of filling the container 101 with the resin composite hydrogen storage alloy will be described with reference to FIG. 2.

まず、カバー３を外した容器１０１の筒体１の端部を、回転駆動手段１３に取り付ける。このとき、筒体１の姿勢は、縦（軸方向が鉛直方向）でもよいし、横（軸方向が水平方向）でもよい。なお、筒体１の姿勢が縦（軸方向が鉛直方向）にされていると、横（軸方向が水平方向）にされている場合よりも、隣り合う板状部２ａの間に注入された樹脂複合化水素吸蔵合金は、隣り合う板状部２ａの間に保持され易い（樹脂複合化水素吸蔵合金がたれて落下するのをより防止することができる）。 First, the end of the cylinder 1 of the container 101 from which the cover 3 has been removed is attached to the rotation driving means 13. At this time, the posture of the cylinder 1 may be vertical (the axial direction is the vertical direction) or horizontal (the axial direction is the horizontal direction). When the posture of the tubular body 1 is vertical (the axial direction is the vertical direction), the injection is performed between the adjacent plate-shaped portions 2a as compared with the case where the cylinder 1 is horizontal (the axial direction is the horizontal direction). The resin composite hydrogen storage alloy is easily held between the adjacent plate-shaped portions 2a (the resin composite hydrogen storage alloy can be more prevented from dripping and falling).

一方で、水素吸蔵合金に合成樹脂を添加混合して、樹脂複合化水素吸蔵合金を作製する。作製した樹脂複合化水素吸蔵合金を、押出機８（注入手段）のホッパ１０に供給する。 On the other hand, a synthetic resin is added and mixed with the hydrogen storage alloy to prepare a resin composite hydrogen storage alloy. The produced resin composite hydrogen storage alloy is supplied to the hopper 10 of the extruder 8 (injection means).

なお、作製した樹脂複合化水素吸蔵合金は、粘性が高く、どろだんご状やクリーム状であり、流動性が悪い。樹脂複合化水素吸蔵合金の注入手段、すなわち、押出機８は、これに限定されるものではないが、例えば、スクリュー式の押出機である。 The produced resin composite hydrogen storage alloy has high viscosity, is in the form of dumplings or cream, and has poor fluidity. The injection means for the resin composite hydrogen storage alloy, that is, the extruder 8, is not limited to this, but is, for example, a screw type extruder.

カバー３を外した容器１０１を回転駆動手段１３に取り付ける工程と、樹脂複合化水素吸蔵合金を作製し、作製した樹脂複合化水素吸蔵合金を押出機８へ供給する工程とは、どちらの工程が先行してもよいし、両工程が並行して行われてもよい。樹脂複合化水素吸蔵合金の硬化速度などによって、どちらの工程を先行させるのか適宜選択される。 Which step is the step of attaching the container 101 from which the cover 3 is removed to the rotation driving means 13 or the step of producing a resin composite hydrogen storage alloy and supplying the manufactured resin composite hydrogen storage alloy to the extruder 8. It may be preceded or both steps may be performed in parallel. Which step should be preceded is appropriately selected depending on the curing rate of the resin composite hydrogen storage alloy and the like.

次いで、押出機８の本体部９の吐出ノズル１１の先端９ａ（吐出位置）を、隣り合う板状部２ａの間の側方近傍に位置させる。その後、樹脂複合化水素吸蔵合金を押出機８から押し出しながら、カバー３を外した容器１０１（螺旋フィン２が外周面に固定された筒体１）を回転駆動手段１３で軸方向Ｚまわりに回転させつつ、隣り合う板状部２ａの間に樹脂複合化水素吸蔵合金を注入していく。 Next, the tip 9a (discharge position) of the discharge nozzle 11 of the main body 9 of the extruder 8 is positioned near the side between the adjacent plate-shaped portions 2a. After that, while extruding the resin composite hydrogen storage alloy from the extruder 8, the container 101 from which the cover 3 was removed (the cylinder 1 in which the spiral fins 2 are fixed to the outer peripheral surface) is rotated around the axial direction Z by the rotation driving means 13. The resin composite hydrogen storage alloy is injected between the adjacent plate-shaped portions 2a.

筒体１（カバー３を外した容器１０１）を軸方向Ｚまわりに回転させながら、隣り合う板状部２ａの間に樹脂複合化水素吸蔵合金を注入していくことで、特許文献１に記載の振動を利用した充填方法よりも、隣り合う板状部２ａの間に樹脂複合化水素吸蔵合金を隙間なく且つ時間効率良く、充填することができる。 Described in Patent Document 1 by injecting a resin composite hydrogen storage alloy between adjacent plate-shaped portions 2a while rotating the cylinder 1 (container 101 from which the cover 3 is removed) in the axial direction Z. The resin composite hydrogen storage alloy can be filled between the adjacent plate-shaped portions 2a without gaps and with time efficiency, as compared with the filling method using the vibration of.

このとき、押出機８の吐出ノズル１１の先端９ａ（吐出位置）を、筒体１（カバー３を外した容器１０１）の軸方向Ｚに沿って移動させながら、隣り合う板状部２ａの間に樹脂複合化水素吸蔵合金を注入していくことが好ましい。これによると、軸方向Ｚに並ぶ全ての板状部２ａの間に、樹脂複合化水素吸蔵合金を効率良く充填することができる。 At this time, while moving the tip 9a (discharge position) of the discharge nozzle 11 of the extruder 8 along the axial direction Z of the tubular body 1 (container 101 from which the cover 3 is removed), between the adjacent plate-shaped portions 2a. It is preferable to inject the resin composite hydrogen storage alloy into the resin composite hydrogen storage alloy. According to this, the resin composite hydrogen storage alloy can be efficiently filled between all the plate-shaped portions 2a arranged in the axial direction Z.

さらには、押出機８の吐出ノズル１１の先端９ａ（吐出位置）を、隣り合う板状部２ａの間に沿わせつつ、当該先端９ａ（吐出位置）を筒体１（カバー３を外した容器１０１）の軸方向Ｚに沿って直線的に移動させながら、隣り合う板状部２ａの間に樹脂複合化水素吸蔵合金を注入していくことが好ましい。この場合、螺旋フィン２が、例えば１条ねじであるとすると、筒体１が１回転したときに、押出機８の吐出ノズル１１の先端９ａ（吐出位置）が、螺旋フィン２の１ピッチ分、ねじが進む軸方向に移動するように、筒体１（カバー３を外した容器１０１）の回転速度と、押出機８の吐出ノズル１１の先端９ａ（吐出位置）の軸方向Ｚへの移動速度とを同期させる。この構成によると、軸方向Ｚに並ぶ全ての板状部２ａの間に、樹脂複合化水素吸蔵合金をより効率良く充填することができる。なお、押出機８の移動手段の図示は、省略されている。 Further, the tip 9a (discharge position) of the discharge nozzle 11 of the extruder 8 is placed between the adjacent plate-shaped portions 2a, and the tip 9a (discharge position) is placed in the cylinder 1 (container from which the cover 3 is removed). It is preferable to inject the resin composite hydrogen storage alloy between the adjacent plate-shaped portions 2a while moving the resin linearly along the axial direction Z of 101). In this case, assuming that the spiral fin 2 is, for example, a single thread, when the tubular body 1 makes one rotation, the tip 9a (discharge position) of the discharge nozzle 11 of the extruder 8 is one pitch of the spiral fin 2. , The rotation speed of the cylinder 1 (the container 101 from which the cover 3 is removed) and the movement of the tip 9a (discharge position) of the discharge nozzle 11 of the extruder 8 in the axial direction Z so that the screw moves in the axial direction. Synchronize with speed. According to this configuration, the resin composite hydrogen storage alloy can be more efficiently filled between all the plate-shaped portions 2a arranged in the axial direction Z. The illustration of the moving means of the extruder 8 is omitted.

全ての板状部２ａの間への樹脂複合化水素吸蔵合金の充填が完了すると、筒体１の回転を停止し、筒体１にカバー３を取り付ける。本実施形態の容器１０１のように、カバー３内において、螺旋フィン２（熱交換部）が配置されていない空間がある場合には、筒体１にカバー３を取り付けた後、樹脂複合化水素吸蔵合金を、この空間に充填する。当該空間は、フィンがないため、カバー３が取り付けられていても、樹脂複合化水素吸蔵合金を容器１０１内に容易に充填することができる。なお、この場合、カバー３（カバー本体４）には、樹脂複合化水素吸蔵合金の充填口が設けられるが、この図示は省略されている。筒体１とカバー３との間の空間Ｓ全体に（空間Ｓの軸方向の端から端まで）、螺旋フィン２（熱交換部）が配置されていてもよい。 When the filling of the resin composite hydrogen storage alloy between all the plate-shaped portions 2a is completed, the rotation of the tubular body 1 is stopped, and the cover 3 is attached to the tubular body 1. When there is a space in the cover 3 in which the spiral fin 2 (heat exchange portion) is not arranged as in the container 101 of the present embodiment, after the cover 3 is attached to the cylinder 1, the resin composite hydrogen is used. This space is filled with a storage alloy. Since the space has no fins, the container 101 can be easily filled with the resin composite hydrogen storage alloy even if the cover 3 is attached. In this case, the cover 3 (cover main body 4) is provided with a filling port for the resin composite hydrogen storage alloy, but this illustration is omitted. Spiral fins 2 (heat exchange portions) may be arranged in the entire space S between the cylinder 1 and the cover 3 (from end to end in the axial direction of the space S).

なお、板状部２ａの間に注入された（容器１０１に充填された）樹脂複合化水素吸蔵合金は、時間が経てば硬化する。 The resin composite hydrogen storage alloy injected between the plate-shaped portions 2a (filled in the container 101) is cured over time.

（容器の変形例）
図３、および図４に示す容器１０２、および容器１０３は、図１に示す容器１０１の変形例である。容器１０２、および容器１０３と、容器１０１との相違点は、容器の内部の熱交換部の構成である。 (Transformation example of container)
The container 102 and the container 103 shown in FIGS. 3 and 4 are modified examples of the container 101 shown in FIG. The difference between the container 102 and the container 103 and the container 101 is the configuration of the heat exchange portion inside the container.

図３に示す容器１０２の熱交換部１２は、複数のリング状の板１２ａ（板状部）が、軸方向Ｚに直交する方向に対して傾斜した姿勢で、所定の間隔をあけて軸方向Ｚに並んだものである。 In the heat exchange portion 12 of the container 102 shown in FIG. 3, a plurality of ring-shaped plates 12a (plate-shaped portions) are inclined in a direction orthogonal to the axial direction Z in the axial direction with a predetermined interval. It is lined up in Z.

また、図４に示す容器１０３の熱交換部２２は、複数のリング状の板２２ａ（板状部）が、軸方向Ｚに直交する姿勢で、所定の間隔をあけて軸方向Ｚに並んだものである。 Further, in the heat exchange portion 22 of the container 103 shown in FIG. 4, a plurality of ring-shaped plates 22a (plate-shaped portions) are arranged in the axial direction Z at predetermined intervals in a posture orthogonal to the axial direction Z. It is a thing.

（樹脂複合化水素吸蔵合金の注入手段）
上記実施形態では、押出機８（例えば、スクリュー式の押出機）を用いて、隣り合う板状部２ａの間に樹脂複合化水素吸蔵合金を注入する例を示した。樹脂複合化水素吸蔵合金の注入手段は、押出機８に限定されない。例えば、容器１０１がより小型な容器である場合などには、シーリング材の注入に用いる公知のコーキングガンなどを用いて、カバー３を外した容器１０１を軸方向Ｚまわりに回転させながら、隣り合う板状部２ａの間に樹脂複合化水素吸蔵合金を注入してもよい。さらには、公知のへらなどを用いて、カバー３を外した容器１０１を軸方向Ｚまわりに回転させながら、隣り合う板状部２ａの間に樹脂複合化水素吸蔵合金を注入してもよい。なお、押出機８を用いて、樹脂複合化水素吸蔵合金を注入すると、隣り合う板状部２ａの間に樹脂複合化水素吸蔵合金を短時間で注入することができる。 (Injection means of resin composite hydrogen storage alloy)
In the above embodiment, an example is shown in which a resin composite hydrogen storage alloy is injected between adjacent plate-shaped portions 2a by using an extruder 8 (for example, a screw type extruder). The injection means of the resin composite hydrogen storage alloy is not limited to the extruder 8. For example, when the container 101 is a smaller container, the containers 101 from which the cover 3 is removed are rotated around Z in the axial direction and adjacent to each other by using a known caulking gun or the like used for injecting a sealing material. A resin composite hydrogen storage alloy may be injected between the plate-shaped portions 2a. Further, a resin composite hydrogen storage alloy may be injected between the adjacent plate-shaped portions 2a while rotating the container 101 from which the cover 3 is removed in the axial direction Z using a known spatula or the like. When the resin composite hydrogen storage alloy is injected using the extruder 8, the resin composite hydrogen storage alloy can be injected between the adjacent plate-shaped portions 2a in a short time.
