Abstract

PROBLEM TO BE SOLVED: To facilitate recovery of a hydrogen storage alloy by a method wherein a part of the alloy-filled part of a container filled with a hydrogen storage alloy is exposed after hydrogen in the container is discharged to the outside, inert gas is introduced to the alloy-filled part and in such a state to hold airtightness of an exposure part is held, an exposure part is covered with an alloy recovery tank, and thereafter, the exposure part is brought into an down state. SOLUTION: A high temperature heating medium flows from a heating medium inlet 1e through a tube handle 7 and flows out through a heating medium outflow outlet 1f, and a hydrogen storage alloy A is heated and hydrogen is discharged. Inert gas is introduced to an alloy-filled part 3 in a container and the periphery of the hydrogen storage alloy A is filled with inert gas. Thereafter, through the flow of a low temperature heating medium from the heating medium inlet 1e through the tube handle 7, the hydrogen storage alloy A in the container is cooled, and a part of the allow-filled part 3 is exposed and covered with a cover 8. Thereafter, an alloy recovery tank 9 is attached to a side position, the alloy- filled part 3 and the cover 8 are rotated in a 90 deg. arc and an exposure part 15 is brought into a down state. This constitution causes the natural drop of the hydrogen storage alloy A from the exposure part 15 and the alloy recovery tank 9 recovers the dropped hydrogen storage alloy.

2. Description of the Related Art Conventionally, a heat pump that utilizes the heat generation or endothermic reaction when a hydrogen storage alloy stores and releases hydrogen, and hydrogen storage that utilizes the property that the hydrogen storage alloy absorbs and releases only hydrogen A hydrogen storage alloy filling container such as a container is known. In these hydrogen storage alloy filled containers, the hydrogen storage alloy in the container becomes fine powder and gradually deteriorates due to repeated storage and release of hydrogen. Therefore, it is desired that the used container containing the hydrogen storage alloy is dismantled and the hydrogen storage alloy, the container and the like are reused.

When exposed to the atmosphere, a hydrogen storage alloy activated to absorb and release hydrogen generates heat due to an oxidation reaction and ignites. If the amount of hydrogen storage alloy filled in the container is small, there is no problem if it is taken out quickly and cooled before ignition, but if it is large and the amount of hydrogen storage alloy is large, it will take a long working time and It is dangerous because it catches fire while being taken out of the container. For this reason, it is very difficult to recover the used hydrogen storage alloy, and it is the current situation that it has not been implemented.

In order to avoid ignition of the hydrogen storage alloy, a method of collecting the hydrogen storage alloy while pouring water on it may be considered.
Certain types of hydrogen storage alloys, such as TiFeCa-based hydrogen storage alloys, react with water and release the remaining hydrogen when the temperature rises, which is dangerous. The shape makes it difficult to take out the hydrogen-absorbing alloy that has been wet with water, and the post-process becomes troublesome unless taken out in a dry state. If the hydrogen storage alloy can be easily taken out from the container and recycled, the effective use of resources and the pollution problem can be solved.

Further, as another disassembling method of the container 1 of the first embodiment, the following method is also possible. First, a high temperature heat medium is passed through the tube bundle 7 to heat the hydrogen storage alloy A filled in the container 1 with the heat medium to release the stored hydrogen, and then the vacuum pump 12 is used to discharge the outer cylinder 2 Air is introduced into the interior from the hydrogen inlet / outlet 1a without sucking the interior. When introducing air, a low-temperature heat medium (refrigerant) is caused to flow through the tube bundle 7 to indirectly cool the hydrogen storage alloy A and suppress the oxidation reaction of the hydrogen storage alloy A.
The air flowing around the hydrogen storage alloy A in a consolidated state does not cause an excessive oxidation reaction with the hydrogen storage alloy A,
Ignition is suppressed in conjunction with the fact that the hydrogen storage alloy A is being cooled.

When the inside of the outer cylinder 2 has reached almost atmospheric pressure in this way, after confirming that the hydrogen storage alloy A does not generate heat, the outer cylinder 2 is exposed to the atmosphere without introducing an inert gas. The cylinder 2 is pulled out to expose the alloy filling portion 3 to form the exposed portion 15. After that, the alloy filling portion 3 is covered with a cylindrical cover 8, and the alloy recovery tank 9 is attached to each opening 8 a of the cover 8. Next, so that the exposed portion 15 faces downward,
The attitude of the container 1 is changed to prompt the hydrogen storage alloy A to fall.

When the hydrogen storage alloy A falls, in order to prevent excessive contact of the hydrogen storage alloy A, which is decomposed into powder particles, with the air, the connection port 8b of the cylindrical cover 8 is used to
An inert gas such as r, N 2 or CO 2 is introduced. As a result, the hydrogen storage alloy A is allowed to fall naturally from the exposed portion 15 while being relatively well filled with the inert gas, and is recovered in the alloy recovery tank 9. In this way, when the hydrogen storage alloy A falls in the form of powder and falls, it is possible to favorably suppress the ignition due to the excessive oxidation reaction. Even during the period from the removal of the outer cylinder 2 to the dropping of the hydrogen storage alloy A, the low temperature heat medium (refrigerant) can be flown through the tube bundle 7 to indirectly cool the hydrogen storage alloy A.

FIG. 6 shows a modification of the first embodiment.
First, after hydrogen in the outer cylinder 2 of the container 1 filled with the hydrogen storage alloy A is released to the outside, the hydrogen storage alloy A in the container 1 is discharged.
The portion filled with is filled with an inert gas. After that, the outer cylinder 2 is removed from the container 1, and one side portion of the holding member 6 that partitions the outer side of the alloy filling portion 3 is removed.
A part of the alloy filling portion 3 filled with is exposed, and the exposed portion 15 (shown by a broken line in FIG. 6) is covered with the alloy recovery tank 9. Then, the alloy filling part 3 is rotated 90 degrees,
The alloy recovery tank 9 is on the lower side. As a result, the hydrogen storage alloy A spontaneously falls from the exposed portion 15 and is recovered in the alloy recovery tank 9. The alloy recovery tank 9 is arranged while maintaining the airtightness of the exposed portion 15, and suppresses the hydrogen storage alloy A from contacting air and igniting as much as possible. The holding member 6 can be divided in advance to partition the outside of the alloy filling portion 3 so that only one side can be removed.
