  • Patent number: 8500836
    Abstract: A centrifugal separator for separating liquid droplets from a gas flow can be used for scrubbing gases to be emitted into the atmosphere, as well as for separating water, oil and gas condensate droplets from a gas flow in any industry. The separator comprises a cylindrical body with axial gas flow inlet and outlet pipes and separated liquid removal sections located on the end surfaces of the body. A swirler and a central perforated pipe are installed in series and in axial alignment in the body from the gas inlet side. A conical displacer is installed in the perforated central pipe. Separation stage vanes are located between the central pipe and the conical displacer along the entire length of the displacer, and hydraulic seal vanes are placed at the same level between the central pipe and the body. The separator design provides a more efficient separation of liquid droplets from a high-velocity gas flow and can operate in any position.

  • Patent number: 6887291
    Abstract: Filter devices and methods for collection of carbon nanomaterials, including fullerenes, produced in gas phase reactors are provided. The filter devices provide for in situ cleaning of filters to release captured product for collection. Product can be released and removed from the reactor without disrupting continuous synthesis of carbon nanomaterials. The filter devices facilitate increased reactor operation and larger scale production of carbon nanomaterials. The filters are cleaned by application of a motive force and/or a gas flow to the filter. In a specific embodiment filters are cleaned by a reverse flow of gas pulses to the filter provided. The invention also provides reactor systems for gas phase synthesis of carbon nanomaterials that can be operated continuously employing the filter device of this invention. Preferred reactor systems are those which synthesize carbon nanomaterials by combustion.

  • Patent number: 4853010
    Abstract: A gaseous stream scrubber includes a cylindrical housing having a curved outer wall for confining therewithin a gaseous stream to be scrubbed. A flow inlet communicates with the housing and introduces the polluted gaseous stream into the housing, the inlet having an axis of flow tangentially placed with respect to the cylindrical housing central axis so that the inflowing gaseous stream creates a circular flow path which spins within the cylindrical housing and about the central axis of the cylindrical housing. A first flow outlet discharges gas from the housing. A centrally placed vortex tube having a bore is centrally positioned in the housing so that the circular flow stream surrounds the vortex tube during operation. In the preferred embodiment, the vortex tube is cylindrical and has a central axis which coincides with the central axis of the cylindrical housing. The vortex tube includes an outlet for discharging gaseous flow from the housing and through the bore of the tube.

  • Patent number: 4351476
    Abstract: An air filtering unit for blowing only filtered air into a room of a building having a central air conditioning air duct outlet therein, includes an electric blower unit having an air inlet and an air outlet. An air guide system conducts all air flowing through the duct outlet into the air inlet of the blower unit. A filter disposed between the air duct outlet and the air inlet of the blower unit filters all air flowing into the blower unit. Air flowing through the outlet of the blower unit is directed into the room in which the air filtering unit is installed or is directed by means of a tubular conduit back through the central air conditioning duct to an outlet duct into another room. The air filtering unit is mounted in a housing disposed over the air duct outlet and has a door which can be opened to expose the filter to facilitate removal and replacement of the filter.

  • Patent number: 4205965
    Abstract: Solid components such as dust particles having a lighter density are sepaed from a flowing medium, such as a gas, wherein the dust is suspended. The gas has the lightest density. For this purpose, the flowing medium which includes the gas and the solid components suspended therein, is detoured in a bent channel and partially introduced into a whirling chamber, which contacts the bent channel along its entire axial height to communicate with the channel along its inner bent portion, whereby the flow produces a centrifugal field in said whirling chamber. Two immersion pipes extend coaxially into the chamber, one pipe from each end. The pipes are connected to suction means, such as fans, for sucking the lighter component out of the whirling chamber. These pipes extend deep enough into the central region of the chamber so that the sucking of the lighter component out of the chamber takes place at said central region of the whirling chamber.
