Provided is an efficient pressure exchange device which can be made more compact and for which the cost can be reduced, without reducing the processing flow rate. This pressure exchange device is equipped with a rotator (40), for which first flow paths (41) through which a first fluid flows in and out and second flow paths (42) 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; a first lateral member (20), for which a first fluid inflow path (21) that guides the first fluid into the first flow paths, a second fluid outflow path (22) that guides the second fluid, in which pressure has been exchanged for the pressure of the first fluid, from the second flow paths, a second fluid inflow path (23) that guides the second fluid into the second flow path, and a first fluid outflow path (24) that guides the first fluid, in which pressure has been exchanged for the pressure of the second fluid, from the first flow paths, are formed in the thickness direction; and a second lateral member (30), for which communication sections (31, 33) that connect the first flow paths and the second flow paths and exchange pressure between the first fluid and the second fluid are formed. The rotator is rotatably sandwiched between the first lateral member and the second lateral member. |
