  • Patent number: 7837752
    Abstract: A rigid or semi-rigid demister pad is positioned between an air turbine and an inertial water removal device such as extractor in an air conditioning system for an aircraft. The demister pad comprises packed fibers or strands whose diameter typically ranges from approximately 10 or fewer microns to approximately 280 microns. The demister is capable of catching very small droplets discharged from the air turbine that coalesce into larger droplets that exit the demister pad and enter an adjacent water removal device downstream from the pad to separate the larger water droplets from the stream of air. This avoids using a water separator containing a coalescer bag that requires frequent maintenance and is sensitive to dirt and freezing. The demister can operate at freezing temperature, is not dirt-sensitive and requires no maintenance.

  • Patent number: 7806966
    Abstract: Compressed Air from an aircraft/rocket engine's compressed air line to its air-conditioning system, or an Auxiliary Air Compressor out-put is used, for energizing a high-speed gas turbine. The very high-speed convoluting air discharge into a vortex cone causes a first separation of the Air gas components, by stratifying into heavier (Argon), medium (Oxygen) and lighter (Nitrogen) components, where in the heavier and lighter components are non-combustible, inert gases and the medium is a combustible gas. The lighter non-combustible component (Nitrogen) exits from the turbine in one direction for storage in the Inert gas tank. The heavier (Argon) and medium (Oxygen) components together move in the opposite direction for having a second stratifying separation downstream in the vortex tube, to separate non-combustible, heavier (Argon) gas from combustible medium (Oxygen) gas components.

    Abstract: A recirculating water extractor includes a swirl vane, a converging nozzle, and two sumps. The recirculating water extractor may be designed to reintroduce uncollected water droplets back into the air stream upstream of both sumps, which may provide additional opportunities for separation. The Coanda effect may be exploited to increase the discharge of water along a surface. Utilizing a converging nozzle may intensify the centrifugal force applied to the air stream rich with entrained water and may move more of entrained water into contact with the wall of the nozzle, which, in turn, may enhance the liquid/vapor separation compared to prior art water extractors. The recirculating water extractor utilizing the Coanda effect and the method for removing entrained water from an air stream may be suitable for, but not limited to, applications in the aircraft and aerospace industries, for example, by being included in environmental control systems of aircraft.

  • Patent number: 7273513
    Abstract: The use of turbulent contactors to simultaneously absorb selected acid gas components from a gas stream and flash off hydrocarbons entrained in a liquid stream which include a solvent or reagent for the selected gas component. In particular, the method comprises feeding the gas stream and liquid stream into a first contactor where they are contacted co-currently and subjected to turbulent mixing conditions, and passing the multi-phase flow from the first contactor to a second contactor. The multi-phase flow from the second contactor is subsequently separated into a gas phase and a liquid phase.

  • Patent number: 7258727
    Abstract: A separating apparatus which enables particles to be separated from a flowing medium by a preliminary separator which avoids the undesirably high pressure losses due to the flow resistance of known preliminary separators. The separating apparatus has a housing with an inlet and an outlet, in which a flow of air at the inlet end is caused to rotate by an inlet guide device, and is redirected again at the outlet end by an outlet guide device into a linear flow. The pressure recovery is achieved by a defined curvature and arrangement of the guide elements. The guide element curvature has an inlet contour, a retarding contour and a stabilizing contour. Preliminary separators of this type are used primarily in the air intake tracts of internal combustion engines exposed to heavy contamination, such as engines in farm machinery or construction machinery.

  • Patent number: 7056368
    Abstract: A powered air cleaning system (1) and air cleaning method are disclosed. The system has a flow path (22) extending through the system from an air inlet (4) to a clean air outlet (5). A motor-driven fan (24) located along the flow path draws particulate debris laden air into the inlet and rotates it about an axis (A—A) to form a rotating flow that stratifies the debris laden air with the heaviest particles in the outermost orbits of the rotating flow. An ejector port (25) is provided for ejecting particulate debris laden air from the stratified rotating flow in the system to the environment. An air filter (9) located within the rotating flow and across the flow path upstream of the outlet filters air from the innermost orbits of the stratified rotating flow.
