摘要:
A device for recovering liquid droplets from a fluid flow stream including a rotatable element comprising wall elements configured to partially enclose a volume with an annular perimeter wall that includes an inside surface radially offset from and facing an axial center, a fixed base wall supports the rotatable element about the axial center, an input fluid conduit delivers the fluid flow stream into the fluid volume, means for rotating the rotatable element for generating a centrifugal force capable of forming a layer of liquid held by the centrifugal force against the inside surface, and an output liquid conduit disposed to collect liquid from the layer of liquid, wherein the layer of liquid rotates with the inside surface with a tangential velocity vector and the collection aperture is fixed in position opposed to the tangential velocity vector such that liquid in the layer of liquid enters the collection aperture.
摘要:
Purge systems and methods are disclosed for flushing unreacted materials and byproducts from a reactor. In one embodiment, the reactor houses a hydrogen generation catalyst and the system comprises a hydrogen generation fuel cartridge containing a reservoir that stores water which may be recovered from the exhaust of a fuel cell. The reservoir may comprise a flexible bladder or a piston-type configuration. Water is delivered from the reservoir to flush the reactor of any residual fuel and/or byproducts.
摘要:
A device (150, 250) for recovering liquid droplets from a fluid flow stream containing the liquid droplets entrained therein includes a rotatable element (164, 256) formed with a partially enclosed fluid volume (184, 262). The fluid is injected into the partially enclosed fluid volume while the rotatable element (164, 256) is being rotated. The rotation generates a centrifugal force capable of moving liquid droplets deposited onto inside surfaces of the partially enclosed fluid volume (184, 262) to a perimeter wall inside surface (172, 284) and to hold a layer of liquid against the inside surface (172, 284). An output liquid conduit (208, 286) is formed to enter into the partially enclosed fluid volume (184, 262) and to position a collection aperture (212, 290) proximate to the inside surface (172, 284) for collecting liquid from the layer of liquid held against the inside surface (172, 284). The device (150, 250) is usable to recover liquid water from the outflow of a hydrogen fuel cell system (100).
