Abstract: A pressure exchange device is equipped with a rotator, for which first flow paths through which a first fluid flows in and out and second flow paths through which a second fluid flows in and out are arranged around a shaft center so as to penetrate through in the direction of the rotation axis. The device includes a first lateral member with a first fluid inflow path, a second fluid outflow path, a second fluid inflow path, and a first fluid outflow path. The device also includes a second lateral member with communication sections that connect the first flow paths and the second flow paths and exchange pressure between the first fluid and the second fluid.

Abstract: A pressure exchanger includes a rotator disposed with pressure transmission sections around a rotation axis. Each pressure transmission section is formed such that a first flow path and a second flow path are communicated with each other. A first lateral member is formed with: first fluid inflow paths guiding the first fluid to the first flow paths; second fluid outflow paths guiding, from the second flow paths, second fluid obtained after pressure exchange with the first fluid; second fluid inflow paths guiding the second fluid to the second flow paths; and first fluid outflow paths guiding, from the first flow paths, first fluid obtained after pressure exchange with the second fluid in the thickness direction. A second lateral member is rotatably sandwiching the rotator between the second lateral member and the first lateral member.

Abstract: Disclosed is a pressure exchange device which can be made more compact and for which the cost can be reduced, without reducing the processing flow rate.
