A heat exchange structure includes: two flow channels stacked in a stacking direction (Y direction) and thermally coupled to each other; and a fin structure detachably installed in at least one flow channel of the two flow channels. The fin structure includes fins arranged in a longitudinal direction (Z direction) of the at least one flow channel in which the fin structure is installed, the fins configured to form openings alternately arranged along the at least one flow channel on one side and the other side of the at least one flow channel in a width direction (X direction).

Heat exchange structure

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.

Jig for inserting filling member into reactor

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.

Reactor with jig provided in pipe for temperature measurement

A fluid disperser includes a plate body installed in a channel, having a first wall portion in a middle region of a first surface facing the upstream side, and provided with a plurality of holes allowing a fluid to flow in from the upstream side to the downstream side, and a second wall portion provided on the first surface and having an inner surface intersecting with a line extending from the middle region to a circumferential edge of the first surface.

Fluid dispersing device

A pressure vessel includes a pressure vessel body provided with a flow channel through which a fluid is caused to flow, having a rectangular cross-sectional shape, and formed to extend in a direction of flow of the fluid, a body flange provided at at least one end side of the pressure vessel body in a longitudinal direction and having a circular cross-sectional shape, and a connecting member connecting the pressure vessel body and the body flange to each other, and the connecting member has a body-flange connected portion connected to the body flange, having a circular cross-sectional shape, and formed in a cylindrical shape, a pressure-vessel-body connected portion connected to the pressure vessel body, being larger in outer shape than the body-flange connected portion, and formed in a cylindrical shape, and a connecting portion connecting the body-flange connected portion and the pressure-vessel-body connected portion to each other and formed in a cylindrical shape with a shape changing to be gradually smaller from the pressure-vessel-body connected portion toward the body-flange connected portion.

Pressure vessel

A pressure vessel comprises a pressure vessel body having a rectangular cross-sectional shape and formed to extend in the direction of flow of fluids, and the pressure vessel body includes a first flow channel which is formed in the longitudinal direction of the pressure vessel body and through which a first fluid is caused to flow, a second flow channel which is formed in the longitudinal direction of the pressure vessel body and through which a second fluid is caused to flow, a first-fluid inlet-outlet port which is provided in one longitudinal end surface of the pressure vessel body and connects with the first flow channel and through which the first fluid is caused to flow in or out, a second-fluid inlet-outlet port which is provided in the other longitudinal end surface of the pressure vessel body and connects with the second flow channel and through which the second fluid is caused to flow in or out, an opening portion which is provided in the one longitudinal end surface of the pressure vessel body and connects with the second flow channel, and a closing member which closes the opening portion in a demountable manner.

A fluid dispersing device includes a tubular first wall portion with an axis extending in a first direction defined as a central axis, and a second wall portion separated downward from the first wall portion. The second wall portion includes at least one circular member and a disk-like member each having a flat surface for causing a fluid passing through an inner space of the first wall portion to collide therewith. The disk-like member is separated downward from the at least one circular member. The at least one circular member has an outer diameter equal to or smaller than an inner diameter of the first wall portion. The disk-like member has an outer diameter equal to or smaller than an outer diameter of the closest circular member.

Fluid dispersing device and heat treatment device

A pressure vessel includes a pressure vessel body provided with a flow channel through which a fluid is caused to flow, having a rectangular cross-sectional shape, and formed in an elongated shape, and a circular body flange provided on at least one longitudinal end side of the pressure vessel body, the pressure vessel body has a fluid inlet-outlet port which is provided on the one longitudinal end side and the body flange side of the pressure vessel body and connects with the flow channel and through which the fluid is caused to flow in or out, and the pressure vessel further includes an inlet-outlet header which is formed between the pressure vessel body and the body flange as a closed space connecting with the fluid inlet-outlet port and which the fluid is caused to flow into and out of.
