Abstract

Provided is a fluid flow-path device with which it is possible to easily perform maintenance that is an operation to remove a foreign substance, which adheres to a member for preventing passage of the foreign material, from the member. This fluid flow-path device is provided with a distribution header including a partition member and a header body disposed in a flow-path formation body. The partition member partitions a distribution space formed by the distribution header into an upstream-side space that communicates with a supply opening provided in the header body, and a downstream-side space that communicates with each of a plurality of flow paths formed in the flow-path formation body. The partition member includes a region that prevents a foreign substance included in a fluid of interest from flowing from the upstream-side space to the downstream-side space while allowing the fluid of interest to flow from the upstream-side space to the downstream-side space. The header body has formed therein an introduction opening that allows a washing fluid to flow into the downstream-side space, and a discharge opening that allows the washing fluid to be discharged from the upstream-side space.

First claim

1 . A fluid flow-path device for supplying target fluid, comprising:
a flow-path formation body having multiple flow paths and a side surface, the multiple flow paths being formed inside the flow-path formation body and allowing a flow of the target fluid in the flow paths and an inlet of each of the multiple flow paths opening at the side surface; and a distribution header arranged on the side surface to cover the inlet of each of the multiple flow paths and forming a distribution space for distributing the target fluid to each of the multiple flow paths between the distribution header and the flow-path formation body, wherein the distribution header includes
a header body having a recessed portion and a supply port, the recessed portion opening to the side surface to form the distribution space in a state in which the distribution header is arranged on the side surface and the supply port being communicated with the distribution space to allow supply of the target fluid to the distribution space through the supply port, and
a partition member provided at the header body at a position in the distribution space, partitioning the distribution space into an upstream-side space communicated with the supply port and a downstream-side space communicated with each of the multiple flow paths at a position closer to the flow-path formation body than the upstream-side space is to, and having a fluid passable portion allowing the target fluid supplied into the space through the supply port to flow to the downstream-side space from the upstream-side space while preventing a foreign substance contained in the target fluid from flowing to the downstream-side space from the upstream-side space, and
the header body is formed with an introduction port and a discharge port, the introduction port is communicated with the downstream-side space such that washing fluid for discharging the foreign substance adhering to the fluid passable portion from an inside of the space to an outside of the distribution header is supplied to the downstream-side space through the introduction port and passes through the fluid passable portion in a direction from the downstream-side space toward the upstream-side space to remove the foreign substance adhering to the fluid passable portion from the fluid passable portion, and the discharge port is communicated with the upstream-side space such that the washing fluid containing the foreign substance removed from the fluid passable portion by passing through the fluid passable portion in the direction from the downstream-side space toward the upstream-side space is discharged to the outside of the distribution header from the upstream-side space through the discharge port.

2 . The fluid flow-path device according to claim 1 , wherein
the partition member further includes a fluid passage blocking portion, and the fluid passage blocking portion is a portion expanding in a direction perpendicular to a supply port opening direction as a direction in which the supply port opens to the side surface of the flow-path formation body and positioned facing the supply port to block passage of the target fluid, and is a portion with which the target fluid supplied to the upstream-side space through the supply port collides with the fluid passage blocking portion before passing through the fluid passable portion such that a flow velocity of the target fluid passing through the fluid passable portion in a direction from the upstream-side space toward the downstream-side space is decreased.

3 . The fluid flow-path device according to claim 2 , wherein
the fluid passage blocking portion has a guide surface, the guide surface expands in a guide direction perpendicular to the supply port opening direction such that the target fluid supplied to the upstream-side space through the supply port and collided with the fluid passage blocking portion is guided in the guide direction in the upstream-side space, and the fluid passable portion expands in a direction perpendicular to the guide direction such that passage of the target fluid flowing in the guide direction along the guide surface of the fluid passage blocking portion after having collided with the fluid passage blocking portion is allowed.

4 . The fluid flow-path device according to claim 3 , wherein
for avoiding collision of the washing fluid supplied to the downstream-side space through the introduction port with the fluid passable portion, the introduction port is positioned on an opposite side of the fluid passage blocking portion from the supply port in the supply port opening direction and on an opposite side of the fluid passable portion from the supply port in the direction perpendicular to the guide direction, and opens in the guide direction.
