  • Patent number: 9616373
    Abstract: An inertial separator includes an inlet portion connected to a Y-junction having a first conduit fluidly extending therefrom and a second conduit fluidly extending therefrom. A separator wall is disposed between and along at least a portion of the first and second conduits. The separator wall has a tip extending into the Y-junction between an inlet to the first conduit and an inlet to the second conduit. An angle is formed between a major longitudinal dimension of the separator wall and the inlet portion centerline, and a ramp is formed adjacent the second end of the generally straight inlet portion, upstream of the Y-junction in a direction of airflow from the inlet opening towards the first and second outlets. During operation, debris entering the inlet portion is separated from an airflow and exits the through the second conduit while air exits through the first conduit.

  • Patent number: 9005340
    Abstract: A fiber bed assembly used to remove aerosols and/or wetted soluble solids from a moving gas stream includes a fiber bed support and a fiber bed supported by the fiber bed support so that the gas stream passes through the fiber bed moving from an upstream space to a downstream space with respect to the fiber bed. A re-entrainment control device is located within a downstream space defined by the fiber bed so that at least a portion of the gas stream passes through the re-entrainment control device. The re-entrainment control device is shaped to change the direction of the average flow path of the gas stream as the gas stream passes through the re-entrainment control device so as to cause aerosols and/or wettable solids contained therein to be separated from the gas stream by inertial force. A re-entrainment control device and method of use are also disclosed.

  • Patent number: 8202336
    Abstract: A system for capturing and separating solids, liquids, and gases, such as during air drilling of a well, can include a cylindrical vessel with an inlet for receiving an input. A target plate can impact the input, remove solid and liquid therefrom, and direct flow from the inlet, forming a vortex. A first chevron baffle, a second chevron baffle, and a demister baffle can further remove solid and liquid from the input, forming a cleaned gas. The cleaned gas can be burned, the solid can be dried, and the liquid can be recycled for reuse in drilling operations.

  • Patent number: 8177887
    Abstract: In one embodiment, an aerosol particle collector includes a duct defining a flow path configured to remove larger particles from aerosol flowing through the duct and to store the removed particles in the duct while maintaining a uniform rate of aerosol flow throughout a predetermined useful life of the duct even as stored aerosol particles accumulate in the duct. In another embodiment, an aerosol particle collector includes a duct and a plurality of baffles in the duct. The duct has an elongated inlet extending along a length of the duct and an outlet located at one end of the length of the duct. A first one of the baffles extends along a first side of the duct for deflecting incoming aerosol toward a second side of the duct opposite the first side. A second one of the baffles is for deflecting aerosol toward the outlet.

  • Publication number: 20120073437
    Abstract: One exemplary embodiment can be a vessel. The vessel can include a body, an inlet, and an impermeable impingement plate. The body may include a substantially cylindrical structure orientated substantially horizontally, and first and second heads coupled at opposing ends of the substantially cylindrical structure. Generally, the body forms an interior space, and a lower portion of the body forms a trough having a length and a width. The inlet can communicate with the interior space of the vessel. Typically, the impermeable impingement plate has an impingement surface. The impermeable impingement plate may have a first side and a second side extending substantially the length of the trough. The first and second sides may be substantially parallel and spaced apart across at least a portion of the width of the trough.

  • Patent number: 8097051
    Abstract: A separator for liquids, in particular condensate, from liquid-loaded compressed gases-generally serves, by coarse separation of condensate from the compressed gases, to protect downstream prefilters of cold dryers or adsorption dryers against overload due to condensate. In the separator of the invention, in a pot-shaped housing, a separator element in the form of a hollow cylinder is arranged, which consists of a multiplicity of flow chicanes formed from guiding bodies and impact bodies. The moisture-loaded gases are passed from the interior of the hollow cylinder to the exterior via these flow chicanes, condensate separating off on the chicanes and collecting in the collecting space.

  • Patent number: 8048184
    Abstract: A baffle tool operative to manually install and remove commercial grill baffles and filters has a longitudinally extensive handle. First and second filter plates pivotally attach to the handle and are operative to couple through a set of prongs with a commercial grill filter. An actuating handle is moveable relative to the longitudinally extensive handle. First and second linking rods extend between the filter plates and actuating handle, and transmit motion of the actuating handle to the first and second filter plates. Movement of the actuating handle thereby causes the filter plates to move relative to the longitudinally extensive handle. A lock is also provided for selectively locking the actuating handle to the longitudinally extensive handle and preventing motion therebetween, which facilitates the securement of a baffle to the tool.

  • Patent number: 7993426
    Abstract: In a moisture separator, a manifold that communicates with a steam inlet is disposed in a shell. A plurality of blowout outlets for steam is provided on a side of the manifold. A first support plate and a lower support frame are fixed to a lower part in the shell to compart a steam drift space and a drain path. A moisture separating element is provided corresponding to the manifold, and steam from which moisture is removed by the moisture separating element is heated by a group of heating tubes to flow as high-temperature reheat steam to the steam outlet. The moisture is led from the drain opening through the drain path to the drain outlet. A blocking plate blocks a part of the drain opening.

  • Patent number: 7981182
    Abstract: A labyrinth box can include a housing that has an open end, a closed end, and defines two cavities. A cover is configured to cover the opening and can include a divider that extends into one of the two cavities of the housing to define first and second chamber passageways in that cavity. An inlet port is located in the bottom closed end of one of the cavities and an outlet port is located in the other of the cavities. The surfaces that define the chambers can be configured such that the box can be oriented in different positions and still work, namely, in horizontal and vertical positions. When in the vertical position, the divider can include surfaces that are angled off of the horizontal plane and towards the inlet port such that water and debris will return to the inlet port via gravity.
