Patent number: 8273158Abstract: A mist eliminator including a substrate and a plurality of frusto-conical shaped protrusions disposed on the substrate is provided. The plurality of frusto-conical shaped protrusions have a geometry and are positioned at intervals that provide coalescence and retention of water particles from moisture containing air contacting the substrate and frusto-conical shaped protrusions. A moisture removal system and a method for removing water particles from inlet air with the mist eliminator are also disclosed.Type: GrantFiled: November 29, 2010Date of Patent: September 25, 2012Assignee: General Electric CompanyInventors: Etienne Rene Jarrier, John Davies, Paul Bryant

Patent number: 8273157Abstract: A solar energy system. The system includes a thermal solar system comprising an air plenum positioned between the system and the underside body. In a specific embodiment, the air plenum is configured according to a specified aspect ratio. The system uses an air moving device to transfer a volume of air through the plenum. The air moving device is configured to maintain a flow rate associated with the volume of air at a specified velocity. The air plenum is configured to reduce the particle concentration of the air traveling through the plenum and to undergo heat treatment for use inside the target building where the thermal solar system is implemented, which keeps the air entering the building clean and healthy.Type: GrantFiled: January 12, 2010Date of Patent: September 25, 2012Assignee: PVT Solar, Inc.Inventor: John James Dyreby

Patent number: 8268052Abstract: A wall assembly for mixing polluted air with less polluted air to provide moderately polluted air. The wall assembly includes means for dividing air from a roadway region into a lower part and an upper part, and means for permitting at least a portion of the upper part to flow substantially in one or more flow directions toward a leeward region. The wall assembly also includes means for directing the lower part substantially upwardly in a direction substantially transverse to the flow direction to intersect with the upper part and to mix the polluted air with the less polluted air, to provide the moderately polluted air proximal to the leeward area.Type: GrantFiled: September 22, 2011Date of Patent: September 18, 2012Assignee: RWDI Air Inc.Inventors: Xin Qiu, Meiring Beyers, Michael Roth, Mark Vanderheyden, Scott Shayko

Patent number: 8252088Abstract: Concentrating particles in a turbulent gas flow may include receiving, in a receptacle, a turbulent gas flow that includes particles. The concentration of particles in a gas flow exiting the receptacle at a first port is increased as compared with a concentration of the particles in the gas flow received by the receptacle. The increased concentration of particles is accomplished by removing a portion of the gas flow by using a second port, and fluidly communicating the gas flow through a tube in the receptacle. The tube has a smaller diameter at the end of the tube at which the gas flow exits the tube than diameter at the end of the tube at which the gas flow is received.Type: GrantFiled: September 19, 2011Date of Patent: August 28, 2012Assignee: L-3 Communications Security and Detection Systems, Inc.Inventors: Thomas D. Plamondon, Nikolay Rolshud, Peter F. Cram, Mark Fraser

Patent number: 8246704Abstract: A contained vortices device that allows for the flow of air or gas into and out of the device. In the process of gases moving through the device, a vortex is created within the device that allows for the separation of heavier materials, reduction of the size of any particulates, and the expelling of particulates of a significantly smaller size than was introduced to the device.Type: GrantFiled: June 3, 2010Date of Patent: August 21, 2012Assignee: Integradigm CorporationInventors: John L. Brock, Alexander Campbell Thompson, IV

Publication number: 20120199001Abstract: A moisture diversion system for a gas turbine inlet. The moisture diversion system comprises a housing that is operably connected with a gas turbine and defines an opening through which air flows to the gas turbine. A hood is attached to the housing adjacent the opening. The hood has a surface disposed at an acute angle relative to horizontal. A device is disposed relative to the hood to separate moisture from air flowing through the device. Separated moisture is directed onto the hood. A gutter is disposed adjacent an edge of the hood to collect moisture from the hood. A conduit is fluidly connected with the gutter to conduct water away from the gutter and the opening in the housing to inhibit separated moisture from re-entering the air flow through the opening to the gas turbine.Type: ApplicationFiled: February 7, 2011Publication date: August 9, 2012Inventors: Rahul Jaikaran Chillar, Adil Ansari
