摘要:
A method of and apparatus for pumping fluids wherein a rotating ring of liquid traverses a hollow probe which has a surface aperture out of which the fluid to be pumped is sucked into the rotating liquid ring, wherein said fluid migrates to a collection region inside the rotating liquid ring, from whence the fluid can pass to a fluid outlet, and wherein a gas which does not condense under the prevailing operating conditions is also fed to the collection region in order to assist throughput of the fluid being pumped.

A liquid ring pump includes a stationary housing that defines an inner space, and a drive shaft rotatably mounted within the stationary housing. The drive shaft defines a rotational axis. An impeller includes a plurality of blades extending radially outward with respect to the rotational axis, and each blade includes a root and a tip, wherein a continuous curve extends from the tip of each blade through the root of the blade and intersects with the rotational axis.

The compressor compresses gas in capillaries leading to a radially distant annular container space. Centrifugal force acts on gas bubbles entrained between liquid slugs moving radially outward through the capillaries which may be radial, tangential or continuously curved. Compressed gas is collected in the annular space. A gas-liquid emulsion is fed to the capillaries by an inboard emulsification device. The emulsification may include a vortex generator, an ejector or a venturi injector, all feeding the gas-liquid mixture into the inboard ends of the capillaries. The capillaries are formed in a series of discs, coaxially stacked with outer disc ends open to the annular space. Capillary inlets may be perpendicular, tangential or may define a venturi jet.

La pompe à fluide décrite comprend un logement cylindrique externe (14) tournant par rapport à un moyeu central (44) d'où s'étend une sonde radiale (52), laquelle est ajourée dans sa surface externe pour être exposée à l'écoulement d'une couronne rotative de fluide opérationnel (14). La sonde comporte un passage interne (54) destiné à placer l'ouverture (56) en communication avec l'extérieur, de sorte que le fluide est aspiré dans la pompe grâce à la force d'aspiration créée au niveau de la sonde. Un tube de Pitot (26) est également exposé au fluide en rotation et est pourvu d'une ouverture à partir de laquelle le fluide est expulsé de la pompe. Le fluide aspiré dans la sonde (52) peut être constitué par un gaz devant être nettoyé par friction et le fluide opérationnel en rotation peut être constitué par un liquide actif destiné à dissoudre les impuretés contenues dans le gaz.

The gas compression method/system restricts flow of emulsified liquid-gas mixture through many substantially radial capillary tube-passages in a rotating disk by either one-way valves, narrowing the passages, hydraulic impedance and/or reinforcement of coriolis forces in terminal end tail segments of the capillary passages. Compressed gas is released from peripherally collected compressed gas-liquid emulsion (beyond the terminal ends of the tubes) in a arcuate peripheral disc space when the compressed gas bubbles emerge from the peripherally collected emulsion. A compressed gas drain draws off gas from the peripheral space. Liquid drain draws off liquid from the space. In different embodiments, radial outboard flow through the capillaries is effected by various one-way valves which may be a single valve in the passage or multiple valves. Coriolis force in tail segments is enhanced by angular displacement in the direction of rotation. Valves may be used in combination with such tail-end segments.

A fluid pump having an outer cylindrical housing (10) rotating relative to an inner hub (44) from which radially projects a probe (52) apertured in its external surface to be exposed to the flow therepast of an annulus of operational liquid (14) constrained in a circular path of motion by the rotating housing, the probe having an internal passage for communicating the aperture with a first external space and the inner liquid-free space in the housing having an outletfor communicating with a second external space. In use, fluid to be pumped is sucked out of the apertured probe to emerge as apertured probe to emerge as fluid bubbles which migrate through the rotating liquid annulus to the liquid-free centre, thence to pass to the outlet.
