PORT GEOMETRY FOR PRESSURE EXCHANGER

摘要

A system includes a rotary isobaric pressure exchanger (IPX) for transferring energy from a high pressure fluid to a low pressure fluid, including a rotor that rotates circumferentially about a rotational axis and having a first end face and a second end face disposed opposite each other with a plurality of channels extending axially between respective apertures located in the first and second end faces. The system includes a first and second end cover with first and second surfaces that slidingly and sealingly engage the first and second end faces. The first and second end covers have at least one fluid inlet and outlet that rotate about the rotational axis and fluidly communicate with at least one channel of the plurality of channels. The fluid inlets have a plurality of apertures, where each aperture has a first leading edge that corresponds to a contour of at least one channel.

1. A rotary isobaric pressure exchanger (IPX) for transferring pressure energy from a high pressure fluid to a low pressure fluid, comprising:
a cylindrical rotor configured to rotate circumferentially about a rotational axis and having a first end face and a second end face disposed opposite each other with a plurality of channels extending axially therethrough between respective apertures located in the first and second end faces; a first end cover having a first surface that interfaces with and slidingly and sealingly engages the first end face, wherein the first end cover has at least one first fluid inlet and at least one first fluid outlet that during rotation of the cylindrical rotor about the rotational axis alternately fluidly communicate with at least one channel of the plurality of channels, and wherein the at least one first fluid inlet has a first aperture at the first surface and the at least one first fluid outlet has a second aperture at the first surface; and a second end cover having a second surface that interfaces with and slidingly and sealingly engages the second end face, wherein the second end cover has at least one second fluid inlet and at least one second fluid outlet that during rotation of the cylindrical rotor about the rotational axis alternately fluidly communicate with at least one channel of the plurality of channels, and wherein the at least one second fluid inlet has a third aperture at the second surface and the at least one second fluid outlet has a fourth aperture at the second surface; and wherein a leading edge of at least one of the first aperture, the second aperture, the third aperture, and the fourth aperture comprises a contour that corresponds to a respective contour of a respective aperture of at least one channel of the plurality of channels.
