Fluid exchanger devices, pressure exchangers, and related methods

摘要

Exchanger devices include a plurality of fixed exchange ducts and a rotating valve assembly for directing flow to and from the plurality of exchange ducts. Methods of exchanging pressure between fluid streams may include directing fluids through an exchange device and pressurizing a fluid in the plurality of exchange ducts of the exchanger device.

主权项

1. A device for exchanging pressure between at least two fluid streams, the device comprising:
a housing having a longitudinal axis and a middle portion forming a plurality of fixed exchange ducts extending in a direction along the longitudinal axis, each exchange duct of the plurality of fixed exchange ducts having openings at a first longitudinal end and a second, opposing longitudinal end; and a rotating valve assembly positioned within the housing for directing flow to and from the plurality of exchange ducts, the rotating valve assembly comprising:
a first valve positioned at and forming an axial seal with the first longitudinal end of the plurality of exchange ducts, the first valve comprising:
a plurality of openings configured to be in selective communication with each exchange duct of the plurality of exchange ducts; andan axial port having an opening extending along a plane perpendicular to a longitudinal axis of the first valve, the opening circumscribing the longitudinal axis of the first valve;a second valve positioned at and forming an axial seal with the second longitudinal end of the plurality of exchange ducts, the second valve comprising:
a plurality of openings configured to be in selective communication with each exchange duct of the plurality of exchange ducts; anda second axial port having an opening extending along a plane perpendicular to a longitudinal axis of the second valve, the opening of the second axial portion circumscribing the longitudinal axis of the second valve; andwherein each of the first valve and the second valve further comprises the axial port at least partially extending along the longitudinal axis of the housing, each axial port being in communication with an associated port formed in the housing extending in a direction along the longitudinal axis of the housing.
