Gas-adsorption device structure and method for using same
Includes gas adsorption device ( 1 ) in which gas adsorbent ( 3 ) is decompression-sealed by first package ( 4 ) with poor gas permeability, and second package ( 2 ) with poor gas permeability. Second package ( 2 ) is at least partially flexible. Air that is a gas that gas adsorbent ( 3 ) can adsorb is filled between gas adsorption device ( 1 ) and second package ( 2 ). In this configuration, gas adsorbent ( 3 ) adsorbs air when first package ( 4 ) is damaged, and thus a pressure inside second package ( 2 ) reduces. Due to this pressure reduction, the shape or dimension of second package ( 2 ) changes. Any damage to first package ( 4 ), i.e., any degradation in adsorption capacity of gas adsorption device ( 1 ), can thus be determined by confirming this change.
1. A gas adsorption device structure comprising:
a gas adsorption device in which a gas adsorbent is decompression-sealed by a first package with poor gas permeability; and
a second package with poor gas permeability for sealing the gas adsorption device, the second package being at least partially flexible;
wherein
a gas that the gas adsorbent can adsorb is filled between the gas adsorption device and the second package.
2. The gas adsorption device structure of claim 1 , wherein a pressure of the gas reduces by the gas adsorbent adsorbing the gas when an inner side communicates with an outer side of the first package due to damage to the first package, and at least one of a shape and a dimension of the second package changes.
3. The gas adsorption device structure of claim 1 , wherein the second package has a transparent part at least in a position where the gas adsorption device can be visually recognized.
4. The gas adsorption device structure of claim 1 , wherein the gas absorbs an impact from outside the second package.
5. The gas adsorption device structure of claim 1 , wherein the second package is at least partially notched.
6. The gas adsorption device structure of claim 1 , wherein the second package has an opening-and-closing structure.
7. The gas adsorption device structure of claim 1 , wherein the gas adsorbent is CuZSM-5.
8. A method of using the gas adsorption device structure of claim 1 , the method comprising step of:
selecting the gas adsorption device structure with the second package of a predetermined shape;
opening the second package of the gas adsorption device structure; and
taking out the gas adsorption device from the gas adsorption device structure,
wherein
the gas adsorption device is used.
