Abstract

<P>PROBLEM TO BE SOLVED: To gradually discharge the high-pressure gas from the inside of a container. <P>SOLUTION: An inlet/outlet part 2 of a metal container body 1 is sealed by a thin metal plate 3. A porous bar-like sintered metal body 5 is fixed to the inside of the inlet/outlet part 2, and sufficiently inserted into the container body 1. A space inside the container body 1 is filled with a liquefied gas adsorbent 6 for sufficiently adsorbing the high-pressure liquefied gas. The high-pressure liquefied gas is filled in the container body 1 with such structure to impregnate the liquefied gas adsorbent 6 with the high-pressure liquefied gas. When a tubular body is connected to the inlet/outlet part 2 to break the thin metal plate 3, the high-pressure liquefied gas impregnated in the liquefied gas adsorbent 6 is vaporized, and the vaporized gas reaches the inlet/outlet part 2 through the sintered metal body 5. Gas is thereby gradually discharged from the inlet/outlet part 2 without being suddenly discharged from the container body 1. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

本発明は、内部に高圧液化ガスを充填し、外部に徐々にガスを放出し得る高圧ガス容器に関するものである。   The present invention relates to a high-pressure gas container that can be filled with a high-pressure liquefied gas and gradually release the gas to the outside.

炭酸ガスなどの高圧液化ガスを充填した高圧ガス容器は、多種の用途に使用されている。   High-pressure gas containers filled with a high-pressure liquefied gas such as carbon dioxide are used for various applications.

しかし、使用に際して容器からガスが急速に排出されるので、短時間に排出が終了してしまうことがある。また、容器の向き方向によって吐出状態が異なる問題もある。これを防止するために、例えばビール吐出装置では液化ガスが急激に吐出しないように、容器の取り付けに角度を付するなどの取付上の各種の工夫がなされている。   However, since the gas is rapidly discharged from the container in use, the discharge may be completed in a short time. There is also a problem that the discharge state varies depending on the direction of the container. In order to prevent this, for example, in the beer discharge device, various devices on the attachment, such as attaching an angle to the attachment of the container, are made so that the liquefied gas is not discharged suddenly.

例えば、特許文献１〜３には、容器内に高圧ガスの液化ガス吸着剤を充填したものが知られている。   For example, Patent Documents 1 to 3 are known in which a container is filled with a liquefied gas adsorbent of high-pressure gas.

しかし、これらの特許文献１〜３は可燃性の高圧液化ガスを使用しており、高圧液化ガスを液化ガス吸着剤に充填し、容器が転倒しても液が流出しないようにしている。   However, these Patent Documents 1 to 3 use a combustible high-pressure liquefied gas and fill the liquefied gas adsorbent with the high-pressure liquefied gas so that the liquid does not flow out even if the container falls.

本発明の目的は、上述の課題を解消し、容器からガスを徐々に排出し得る高圧ガス容器を提供することにある。   An object of the present invention is to provide a high-pressure gas container capable of eliminating the above-described problems and gradually discharging gas from the container.

上述の目的を達成するための本発明に係る高圧ガス容器は、容器本体の出入口部から内部に棒状の多孔質体を挿入し、前記容器本体内の空間に液化ガス吸着剤を充填し、該液化ガス吸着剤に高圧液化ガスを含浸させ、ガス排出時には前記多孔質体を介して前記液化ガス吸着剤からガスを放出させて容器本体の外部に排出することを特徴とする。   In order to achieve the above object, a high-pressure gas container according to the present invention has a rod-shaped porous body inserted therein from an inlet / outlet portion of a container body, and a space in the container body is filled with a liquefied gas adsorbent, The liquefied gas adsorbent is impregnated with a high-pressure liquefied gas, and when the gas is discharged, the gas is discharged from the liquefied gas adsorbent through the porous body and discharged to the outside of the container body.

本発明に係る高圧ガス容器によれば、容器内において液化ガス吸着剤に吸着されたガスは、多孔質体を介して安定した排出量で長時間に渡って徐々に排出される。   According to the high-pressure gas container of the present invention, the gas adsorbed by the liquefied gas adsorbent in the container is gradually discharged over a long time with a stable discharge amount through the porous body.

本発明を図示の実施例に基づいて詳細に説明する。
図１は断面図であり、金属製の容器本体１の出入口部２は薄肉金属板３により密封されている。出入口部２の内側には接続ソケット４が取り付けられ、この接続ソケット４には多孔質の棒状の焼結金属体５が固定され、容器本体１の内部に十分に挿入されている。 The present invention will be described in detail based on the embodiments shown in the drawings.
FIG. 1 is a cross-sectional view, and an entrance / exit portion 2 of a metal container body 1 is sealed with a thin metal plate 3. A connection socket 4 is attached to the inside of the entrance / exit portion 2, and a porous rod-like sintered metal body 5 is fixed to the connection socket 4 and is sufficiently inserted into the container body 1.

そして、容器本体１内の空間には、高圧液化ガスを十分に吸着する活性炭、モレキュラーシーブ等の液化ガス吸着剤６が充填されている。   The space in the container body 1 is filled with a liquefied gas adsorbent 6 such as activated carbon or molecular sieve that sufficiently adsorbs the high-pressure liquefied gas.

このように構成した容器本体１内に、炭酸ガス等の高圧液化ガスを充填して、液化ガス吸着剤６に含浸させる。   The container body 1 configured in this manner is filled with a high-pressure liquefied gas such as carbon dioxide gas and impregnated in the liquefied gas adsorbent 6.

使用に際しては、ガスを充填した高圧ガス容器の出入口部２に管体等を連結し、薄肉金属板３を破る。これにより容器本体１内に圧力が急速に降下し、液化炭酸ガスは短時間で膨張し、伝熱時間が殆どないので断熱膨張する。この断熱膨張により温度が低下するため、液化炭酸ガスはこのときドライアイスに変化する。これにより、熱量の減少を抑制し、液化ガス吸着剤６に含浸されている高圧液化ガスが気化される。   In use, the thin metal plate 3 is broken by connecting a tube or the like to the inlet / outlet part 2 of the high-pressure gas container filled with gas. As a result, the pressure rapidly drops in the container main body 1 and the liquefied carbon dioxide gas expands in a short time, and since there is almost no heat transfer time, it adiabatically expands. Since the temperature is lowered by this adiabatic expansion, the liquefied carbon dioxide gas changes to dry ice at this time. Thereby, the reduction | decrease in calorie | heat_amount is suppressed and the high voltage | pressure liquefied gas impregnated by the liquefied gas adsorbent 6 is vaporized.

しかし、気化されたガスは焼結金属体５中を通り出入口部２に達するので、ガスが急激に容器本体１から排出されることなく、出入口部２から徐々に放出されることになる。   However, since the vaporized gas passes through the sintered metal body 5 and reaches the inlet / outlet part 2, the gas is gradually discharged from the inlet / outlet part 2 without being rapidly discharged from the container body 1.

本実施例の高圧ガス容器と、通常の内部に何も設けない標準容器の場合に、それぞれ液化高圧炭酸ガスを充填し、ガス放出時間を比較すると、次のような数値が得られた。   In the case of the high-pressure gas container of the present example and a standard container having nothing inside, a liquefied high-pressure carbon dioxide gas was filled and the gas release times were compared. The following numerical values were obtained.

実施例容器 標準容器
充填圧力 ９ＭＰａ ９ＭＰａ
充填量 １３ｇ １５ｇ
ガス放出時間 ９分〜１０分 ５秒 Example container Standard container Filling pressure 9 MPa 9 MPa
Filling amount 13g 15g
Gas release time 9 minutes to 10 minutes 5 seconds

なお、焼結金属体５は径５ｍｍ、長さ４３ｍｍであり、ガス放出は減圧弁により０．９ＭＰａに減圧して吐出している。この結果によれば、本実施例の場合は、極めて緩慢にガスが放出され、用途によって有用となる。   In addition, the sintered metal body 5 has a diameter of 5 mm and a length of 43 mm, and gas discharge is performed by reducing the pressure to 0.9 MPa by a pressure reducing valve. According to this result, in the case of the present embodiment, the gas is released very slowly, which is useful depending on the application.
