Abstract

A jig for inserting a packing into a flow passage of a reactor extending in one direction or for removing the packing from the flow passage, includes: a pair of strip portions extending in parallel with each other, having a length longer than the flow passage; and link portions arranged in an extending direction of the pair of strip portions, linking the pair of strip portions and having lengths with which the pair of strip portions sandwich the packing therebetween.

First claim

What is claimed is:

1. A jig for inserting a packing into a flow passage of a reactor extending in one direction or for removing the packing from the flow passage, comprising:
a pair of strip portions extending in parallel with each other, having a length longer than the flow passage; and
link portions arranged in an extending direction of the pair of strip portions, linking the pair of strip portions and having lengths with which the pair of strip portions sandwich the packing between the pair of strip portions.

2. The jig according to claim 1 , wherein
each of the strip portions includes:
a tip end portion provided as one end in the extending direction; and
a base end portion provided as the other end in the extending direction, and

the tip end portion of one of the pair of strip portions is inclined to approach the strip portion of the other of the pair of strip portions.

3. The jig according to claim 2 , wherein
the link portions include:
first link portions positioned on a side with the tip end portion and provided at intervals longer than the packing in the extending direction of the pair of strip portions; and
at least one second link portion positioned closer to the base end portion than the first link portions.

4. The jig according to claim 3 , wherein
each of the first link portions is connected to a center of each strip portion in a width direction thereof.

5. The jig according to claim 4 , wherein
at least one of the at least one second link portion is located at a part of the pair of strip portions, the part being exposed from the flow passage.

6. The jig according to claim 3 , wherein
each second link portion is connected to a position shifted from a center of each strip portion in a width direction thereof.

7. The jig according to claim 6 , wherein
at least one of the at least one second link portion is located at a part of the pair of strip portions, the part being exposed from the flow passage.

8. The jig according to claim 3 , wherein
at least one of the at least one second link portion is located at a part of the pair of strip portions, the part being exposed from the flow passage.

9. The jig according to claim 1 , wherein
the link portions include:
first link portions positioned on a side with a tip end portion and provided at intervals longer than the packing in the extending direction of the pair of strip portions; and
at least one second link portion positioned closer to a base end portion than the first link portions.

10. The jig according to claim 9 , wherein
each of the first link portions is connected to a center of each strip portion in a width direction thereof.

11. The jig according to claim 10 , wherein
at least one of the at least one second link portion is located at a part of the pair of strip portions, the part being exposed from the flow passage.

12. The jig according to claim 9 , wherein
each second link portion is connected to a position shifted from a center of each strip portion in a width direction thereof.

13. The jig according to claim 12 , wherein
at least one of the at least one second link portion is located at a part of the pair of strip portions, the part being exposed from the flow passage.

14. The jig according to claim 9 , wherein
at least one of the at least one second link portion is located at a part of the pair of strip portions, the part being exposed from the flow passage.

15. The jig according to claim 1 , wherein
the flow passage is a reaction flow passage through which a reaction fluid flows, and
the packing is a catalyst body.
