A portion of the larger particles leaves the major flow and merges with the minor flow due to particle momentum, thus increasing the large-particle concentration of the minor flow. The acceleration nozzle incorporates convex curvature along its opposed interior surfaces, for a smoother aerosol flow and reduced large-particle deposition.

The pressurized air/oil mixture produced by the compressor, passes through conduit (4) to enter separation tank (5) in which the separation of the oil from the air occurs. The air under pressure passes through radiator (6) and fills accumulation tank (7) waiting to be used, while the oil (8) deposited at the bottom of the separator, is picked up by conduit (9) and passes through radiator (10) to be brought again to compressor (2). This separation tank is characterized by the fact that the entry port of the air/oil mixture is placed on the upper wall or cover of the vessel.

  • Patent number: 6666338
    Abstract: A device for the separation of solid objects (9) from fluid flowing in a conduit tube (2) includes a housing that includes a tubular outer wall (3) and a tubular inner wall (4). Between these is delimited a collecting space (8). Concentrically relative to the inner wall (4) is provided a rotation-symmetrical central body (12) which at opposing ends cooperates with flow converting devices (15, 16), which transform incoming flow to a rotative motion and outgoing flow to an axial motion. In the inner wall (4) are recessed tangentially separated holes (20) of elongated shape, through which the scrap objects may pass and be collected in a collecting space (8). In the collecting space (8) a calm flow operation is obtained which guarantees that collected scrap objects are not carried away and returned to the main fluid flow through the separation device.

  • Patent number: 6485536
    Abstract: The invention is a particle separator which separates entrained particulates from a fluid. The particle separator utilizes an auger enclosed within a cylinder to form a cyclonic chamber, through which air is propelled. The centrifugal motion of particles within the air causes the particles to exit the cyclonic chamber through ducts, and the particles are separated in collection chambers.

  • Patent number: 6019825
    Abstract: A hydrocyclone for separating a combined phase input stream has two nesting truncated, downwardly tapering conical members having an annular space therebetween. A tangential inlet leads to the annular space between the conical members. Alternate embodiments applicable to a hydrocyclone device composed of nesting cylindrical or conical shells forming an annular cyclonic space have passages located on either of the shells to effect an intermediate draw off of a fraction of the flow stream. In addition, a coiled, hollow tube is advantageously situated within the annular space to optimize the flow pattern. Ports may be provided in the hollow tube for removing a gas fraction in counterflow orientation.

  • Patent number: 5800578
    Abstract: A separating system for separating material transported by air utilizing apparatus having a tangential inlet for a stream of air and entrained material, a bottom material exit, a boundary wall air exit and a central interior air exit. Each air exit includes a perforated wall or screen through which air is removed or separated from the entrained material. Enhanced separating action is achieved through coupling two such separators in a loop arrangement such that the material discharge from a first separator is conveyed via a relay stream of air to serve as the input to a second separator, while the entire air exhaust from the second separator is returned as one of a plurality of inlet streams to the first separator. A further advantage is realized by partitioning the air exhaust of the first separator into a plurality of parallel passageways which can be individually closed.

  • Patent number: 5634964
    Abstract: An air mixer, with a water collector, is disclosed for supplying recirculated cabin air in aircraft. In the preferred embodiment: used cabin air flows over pipes of colder fresh air to cool the used air and condense out most of the moisture contained in it; the fresh air and used air are passed over opposite faces of a ring of stator vanes, thereby imparting swirls to both types of airstreams; and the streams meet at the trailing tips of the stator vanes, where they corkscrew together to throw remaining coalesced moisture against a collection trough, from where it is discharged. The airstreams can now be injected into the cabin without droplets raining down on the passengers, nor ice clogging any pipes for the fresh air, which is typically supplied at below-freezing temperature.
