  • Publication number: 20020157993
    Abstract: The present invention employs a virtual impactor to separate a flow of fluid into a major flow and a minor flow, such that the minor flow contains a higher concentration of particulates of a desired size. The minor flow is directed toward an archival surface, causing the particulates to impact against and be deposited on the archival surface. Over time, the archival surface and the virtual impactor are moved relative to one another such that particulates collected at different times are deposited as spaced-apart spots on different portions of the archival surface. The particulates are stored on the archival surface until analysis of the particulates is required. The archival surface can be coated with a material that enhances the deposition and retention of the particulates and can further be coated with materials that sustain the life of biological organism particulates deposited on the archival surface.

    Abstract: An opposed-flow virtual cyclone for aerosol collation which can accurately collect, classify, and concentrate (enrich) particles in a specific size range. The opposed-flow virtual cyclone is a variation on the virtual cyclone and has its inherent advantages (no-impact particle separation in a simple geometry), while providing a more robust design for concentrating particles in a flow-through type system. The opposed-flow virtual cyclone consists of two geometrically similar virtual cyclones arranged such that their inlet jets are inwardly directed and symmetrically opposed relative to a plane of symmetry located between the two inlet slits. A top plate bounds both jets on the "top" side of the inlets, while the other or lower wall curves "down" and away from each inlet jet. Each inlet jet will follow the adjacent lower wall as it turns away, and that particles will be transferred away from the wall and towards the symmetry plane by centrifugal action.

  • Patent number: 5989302
    Abstract: A steam separator achieves primary separation by directing the flow of a steam-water mixture against a baffle. The baffle redirects the flow so that the steam-water mixture is directed toward the surface of accumulated water ordinarily present in the separator. The liquid components of the steam-water mixture collect on the baffle and drip down into the accumulated water. The steam components pass around the edge of the baffle and escape upwardly. To improve the effectiveness of the separator, the edge of the baffle is extended below the water surface and openings or gables are formed in the baffle above the level of the water surface. The spaces between the gables provide a surface along which the separated liquid water component can flow undisturbed into the accumulated water, and the gables provide ports through which the steam component can escape from the baffle without reentraining significant amounts of the separated liquid water component.

  • Patent number: 5858043
    Abstract: The invention relates to virtual impactors with slit-shaped nozzles. Virtual impactors serve to enrich aerosol particles of certain magnitudes from gases, particularly from ambient air, for the purpose of examining these particles. For very strong enrichments, reaching up to many hundreds of times the initial concentration, very effective multi-stage virtual impactors with hundreds of nozzles have been developed. However, these are difficult to manufacture and to clean. The individual nozzles can be replaced by slits which are easier to manufacture. With slit-shaped nozzles problems with instability at the ends of the slits occur. The invention describes slit-shaped nozzles, the slits of which have no ends because they are designed as curved, closed figures. By contrast with the prior art which relates to circular slits in parallel plates, here any closed figures are represented, including ones which are not in plane-parallel plates.

The first stage includes an entrance area to the trap that is purposely designed to be large in space and a very poor heat exchanger in order to avoid condensation and resulting solid deposits that could clog the entrance port to the trap. The second stage comprises a better heat exchanger to spread the condensation and deposits efficiently over a larger surface area and a longer flow path. The second stage is a very efficient heat exchanger to clean up and remove whatever small amount of the condensable vapor remains after the first stage of the trap. The second stage includes cooling coil tubes and cooling cones or fins to increase the overall efficiency of the trap be increasing the interior surfaces upon which the flowing condensable vapor can condense, while not significantly reducing the flow conductance of the trap.

  • Patent number: 5391220
    Abstract: A pollution control system and method in which hot flue gas is cooled to saturation in a quencher and passed through a condenser absorber assembly to further cool the saturated gases while growing small particles as the particles act as nuclei for the condensation of water vapor thereon. The grown particles are carried through an aperture having a low pressure drop throat so that high efficiency particle collection is accomplished. At its outlet, the aperture produces a concentration of the gases and water droplets. A dome shaped gas reverser, having its concave surface directed upstream, is located spaced apart from the aperture and in substantial alignment with the outlet of the aperture. The gas reverser receives the gas stream as it exits the aperture, mixing and diffusing the gas and its constituents as they change direction to spill out over the lip of the gas reverser.
