Abstract

A reactor includes: a heat exchange section including: a first flow channel configured to flow a reaction fluid and a second flow channel configured to flow a heat medium; an introduction path for a temperature sensor, extending from an insertion opening provided on a side surface of the heat exchange section to the first flow channel or the second flow channel; a pipe for a temperature sensor, connected to a side surface of the heat exchange section and communicating with the introduction path through the insertion opening; and a jig provided in the pipe. The jig is provided with a guide hole extending from the base end toward the tip end and opened toward the insertion opening of the introduction path. The guide hole is provided with a tapered hole directed from the base end toward the tip end.

First claim

What is claimed is:

1. A reactor comprising:
a heat exchange section including:
a first flow channel configured to flow a reaction fluid, and
a second flow channel configured to flow a heat medium;

an introduction path for a temperature sensor, extending from an insertion opening provided on a side surface of the heat exchange section to the first flow channel or the second flow channel;
a pipe for a temperature sensor, connected to the side surface of the heat exchange section and communicating with the introduction path through the insertion opening; and
a jig provided in the pipe, including a tip end facing the insertion opening of the introduction path and a base end positioned on a side opposite to the tip end;

wherein
the jig is provided with a guide hole extending from the base end toward the tip end and opened toward the insertion opening of the introduction path,
the guide hole is provided with a tapered hole directed from the base end toward the tip end,
the pipe includes a thin-wall part having an inner diameter of the maximum diameter or more of the jig, and a thick-wall part having an inner diameter of less than the maximum diameter of the jig, and
the thin-wall part is located at an end portion of the pipe facing the side surface of the heat exchange section.

2. The reactor according to claim 1 , wherein
the jig is movably provided in the pipe.

3. The reactor according to claim 2 , wherein
the jig includes a large-diameter portion located on a base end side and a small-diameter portion located on a tip end side, the small-diameter portion having an outer diameter smaller than an outer diameter of the large-diameter portion.

4. The reactor according to claim 1 , wherein
the inner diameter of the thick-wall part is less than the opening diameter of the tapered hole at the base end of the jig.

5. The reactor according to claim 1 , wherein
the jig is fixed in the pipe.
