The wet electrostatic ionization stage includes a plate disposed across a cross section of a flow channel and connected to a ground potential or reference counterpotential. The plate includes substantially identical openings through which the gas flows. The wet electrostatic ionization stage also includes a high-voltage grid disposed across the cross section of the flow channel either upstream or downstream from the plate and electrically isolated from a wall of the flow channel. The high voltage grid is coupled to a high voltage potential via a bushing disposed in the wall of the flow channel. For each opening in the plate, a rod-shaped high-voltage electrode coupled at one end to the high-voltage grid has a free end projecting centrically into the one opening.Type: GrantFiled: March 11, 2006Date of Patent: April 14, 2009Assignee: Forschungszentrum Karlsruhe GmbHInventors: Andrei Bologa, Thomas Waescher, Hanns-Rudolf Paur, Ralf Arheidt

Patent number: 7507275Abstract: A surface discharge type air cleaning device including an insulating dielectric body formed in the shape of a sheet, a discharge electrode formed at the upper surface of the insulating dielectric body, and a ground electrode formed at the lower surface of the insulating dielectric body. The discharge electrode is formed of a closed pattern having a predetermined area on the upper surface of the insulating dielectric body. The discharge electrode has a non-pattern part disposed in a pattern part where the pattern is formed. The electrode is not formed at the non-pattern part. The ground electrode is formed at a predetermined position corresponding to the non-pattern part. The area of the non-pattern part is reduced to decrease generation of ozone, and the area of the pattern part is enlarged to increase generation of negative ions and hydroxyl radicals.Type: GrantFiled: December 29, 2005Date of Patent: March 24, 2009Assignee: LG Electronics Inc.Inventors: Ho Jung Kim, In Ho Choi, Kwan Ho Yum, Ho Seon Choi

Patent number: 7452410Abstract: In various aspects of the invention, electrostatic filters having insulated electrodes are described. In such embodiments, care is taken to prevent the accumulation of opposing charges on the insulation, which, over time, would serve to significantly degrade the strength of the electrostatic field created in the dielectric, and thus reduce the performance of the electrostatic filter. A variety of mechanisms are described for mitigating the opposing charge buildup problem.Type: GrantFiled: April 18, 2006Date of Patent: November 18, 2008Assignee: Airinspace B.V.Inventors: Vance Bergeron, Laurent Adrien Fullana

Patent number: 7384456Abstract: A modular frame for use in air purification devices is described. In one aspect of the invention, a plurality of frame members are arranged in a linked stack to form a housing for components of an air purification device. The frame members are arranged to define a flow channel through which a fluid stream passes and to support components of the air purification device that receive the fluid stream. In another aspect of the invention, a plurality of rods are arranged to pass through the frame member stack. A first one of the rods serves as an electrical power source at a first potential and a second one of the rods serves as an electrical power source at a second potential. Electrical connectors are provided to electrically couple electrodes on selected components of the air purification device to their associated rods. In devices that utilize electrostatic filters, the electrodes that are connected to the rods may include the electrodes of the electrostatic filters.Type: GrantFiled: May 31, 2006Date of Patent: June 10, 2008Assignee: AirInSpace B.V.Inventor: Patrick Aubert

Patent number: 7377962Abstract: A discharge device for generating a streamer discharge includes a discharge electrode and a counter electrode. The discharge electrode is in a shape of a wire or rod and is disposed substantially parallel to the counter electrode. Thus, even when a tip of the discharge electrode becomes worn out, a shape of the tip of the discharge electrode remains unchanged and a distance between the discharge electrode and the counter electrode remains unchanged. As a result, even when the tip of the discharge electrode becomes worn out, the streamer discharge stability will not fall.Type: GrantFiled: June 22, 2004Date of Patent: May 27, 2008Assignee: Daikin Industries, Ltd.Inventors: Toshio Tanaka, Kanji Motegi, Kenkichi Kagawa
