| 20080216657 | Air Purifier for Removing Particles or Contaminants from Air - An air purifier includes a housing having an air inlet, an air outlet and an airflow path therethrough. The housing has a top, a bottom and a plurality of sides. An air filter is located within the housing in the airflow path and a motor is located within the housing. The motor includes a motor shaft and a fan is on the motor shaft for urging air into the air inlet, through the airflow path and out of the air outlet. A cover is removably mounted to the housing proximate the air inlet and a base is removably mounted to the housing. The air purifier is positionable in one of a vertical operating orientation when the weight of the housing is supported by the base and a horizontal operating orientation when the weight of the housing is supported by one of the sides of the housing. | 09-11-2008 |
| 20080257156 | Carbon Nanotubes As Low Voltage Field Emission Sources for Particle Precipitators - An air particle precipitator and a method of air filtration comprise a housing unit; a first conductor in the housing unit; a second conductor in the housing unit; and a carbon nanotube grown on the second conductor. Preferably, the first conductor is positioned opposite to the second conductor. The air particle precipitator further comprises an electric field source adapted to apply an electric field to the housing unit. Moreover, the carbon nanotube is adapted to ionize gas in the housing unit, wherein the ionized gas charges gas particulates located in the housing unit, and wherein the first conductor is adapted to trap the charged gas particulates. The air particle precipitator may further comprise a metal layer over the carbon nanotube. | 10-23-2008 |
| 20080302244 | Carbon dioxide absorption device - Carbon dioxide contained within exhaust gas is combined with bivalent metal ions such as calcium ions or the like in concentrated salt water to form precipitated calcium carbonate and then can be expelled out. Such an environmental friendly design is realized by a bottle upside down device with a bottle neck exit on a bottom, a piston inside the device can be elevated to a top portion to produce a near vacuum air pressure inside the device. All the brine, exhaust gas, and oxygen, ozone draw together into the device can be accelerated to form, at least, precipitated calcium carbonate to reduce carbon dioxide contained within the exhaust gas. Chemical reaction accelerated by a high voltage discharger below the piston, by flashing a portion of water to atomize the brine. Or a heater can heat up the near vacuum device to accelerate chemical reaction. | 12-11-2008 |
| 20090188390 | ELECTROSTATIC PRECIPITATOR - There is provided an electrostatic precipitator comprising air inlet means to a conduit for the passage of an air flow containing particles and means generating a focusing electrostatic field within the conduit substantially orthogonal to the air flow in which the generating means comprise a two dimensional surface electrode including an ion source and an earthed counter electrode and in which the air inlet means and the surface electrode are adapted to direct ion substantially against the direction of the air flow in the conduit. | 07-30-2009 |
| 20090288558 | Nonwovens of controlled stiffness and retained foldability - The present disclosure relates generally to a nonwoven filtration media comprising a bonded mix of different, discontinuous, thermoplastic resin fibers and optionally discontinuous cellulosic fibers. The nonwoven media has an advantageous combination of stiffness, foldability, efficiency and the ability to retain a fold. The nonwoven media can be thermally bonded during the production process. The advantageous combination of mechanical properties allow the disclosed nonwoven media to accept and retain folds and pleats better than some conventional filtration materials while the mix of different fibers provides desirable filtration properties. | 11-26-2009 |
| 20100011960 | Electrostatic Air Filter - The invention provides a filter for separating very small particles or organisms from the air or gas in which they are carried, comprising a filter mechanism and a duct, chamber or pipe to contain and transport the air or gas and to house the filter mechanism; the filter mechanism comprising: a particle charging means, a means to introduce charged or uncharged atomized droplets of liquids or reagents into the air or gas after the particle charging stage, and a capture means for collecting the atomized droplets and/or very small particles or organisms. | 01-21-2010 |
| 20100018398 | ASSEMBLY AND HOUSING FOR DUCT SYSTEM - An assembly for use in a fully or partially-enclosed structures (such as an HVAC duct) includes a housing, a tube mounting member and a tube for generating ions. The housing has a cavity that can be accessed by removing a cover, and the tube may be removed from the tube mounting member without unscrewing or removing any components attached to the structure. | 01-28-2010 |
| 20100192773 | ABATEMENT APPARATUS WITH SCRUBBER CONDUIT - Embodiments of an abatement apparatus are disclosed herein. In some embodiments, an abatement apparatus may include a scrubber configured to receive an effluent stream from a process chamber and further configured to remove first particles from the effluent stream; a scrubber conduit coupled to the scrubber to receive the effluent stream therefrom and configured to remove second particles from the effluent stream, the scrubber conduit having one or more inlets configured to provide a fluid to sufficiently wet an interior surface of the scrubber conduit to trap the second particles thereon and to wash the second particles therealong; and a central scrubber coupled to the scrubber via the scrubber conduit. In some embodiments, the scrubber conduit is downward sloping from the scrubber to the central scrubber. In some embodiments, a plurality of scrubbers may be coupled to the central scrubber via a plurality of scrubber conduits. | 08-05-2010 |
