摘要:
A recipient for a gas ultracentrifuge which comprises an oblong cylindrical shell having a lid closing each end, a base flange having an upper end surrounding one end of the shell and a plastically deformable ring interposed between the base flange and the shell. In an embodiment of the invention, the plastically deformable ring comprises a ring-shaped section and a welding shoulder which forms a ring-shaped collar integral with the base flange, the thickness of the shell being greater than that of the ring-shaped collar and about the same thickness as that of the welding shoulder.
摘要:
Turbo-separative methods and apparatus for separation of mixtures of gaseous materials having different molecular weights, particularly gaseous isotope mixtures such as mixtures of UF.sub.6, in which differential sedimentation velocities of the components to be separated are established in a laminar boundary layer of the gas adjacent a hydraulically smooth, porous blade surface, and in which a predetermined amount of the boundary layer flow is conducted through the porous surface to stabilize the boundary layer and to provide a higher density gas fraction. The velocity of the gas conducted through the porous blade surface should not exceed the sedimentation velocity of the gas species to be separated.
摘要:
A device for the separation of gaseous mixtures into components of differing molecular mass. The device is designed according to the principle underlying a turbine or a turbomolecular pump. The device has a rotor that is equipped with discs made of magnetic material having blades at their periphery and is installed in a stationary casing having a gaseous mixture inlet and at least two gas outlets connected to a gas delivery tube, and to whose inside wall stator discs are attached between the rotor discs. The device further has voltage means. The gas delivery tube has controls connected thereto which keep the total pressure in the gaseous mixture below 10 Pa.
摘要:
A gaseous mixture ultracentrifuge has a hollow cylindrical rotor having its ends closed by end covers through which inlet and outlet holes are formed, the rotor being internally free from non-rotative parts, while non-rotative means on the outsides of the end covers provide via the holes, for feeding the gaseous mixture into the rotor through one of the end pieces, and for removing separated components of the mixture through the outlet holes of the end covers.
摘要:
A separator intended for use in dividing air into relatively warm and cool components is provided with an elongated cylindrical housing having one open end. The housing encloses a rotatably mounted and motor driven impeller having a portion near the open end for moving air axially and a portion near the opposite end of the housing for moving air radially thereof. The opposite end of the housing has means which carries away warm air from an area near the longitudinal axis of the impeller while other means radially spaced from the axis carries away relatively cool air.
摘要:
A centrifugal separator using a lyophobic filter for removing liquid particles from a mixed stream of gas and liquid under various negative or positive external acceleration conditions as well as zero g or weightless conditions. Rotating the lyophobic filter and inclining the filter to the entering flow improves the lyophobic properties of the filter, provides gross separation of larger liquid particles and prevents prolonged contact of liquid droplets with the spinning filter which might change the filter properties or block the filter.
摘要:
A deaerator comprising a rotating chamber having a nozzle exhausting by centrifugal force the liquid of an entrained gas/liquid feed into an outer liquid body while the entrained gases are withdrawn from the interior of the chamber through a separate gas outlet under a reduced pressure.
