    Abstract: An airborne particulate sampling device is disclosed. The device includes a conduit whose interior allows the flow of air through the device. The conduit, or at least its surface, is a conductor. The device also includes an electrode with a sharp tip or edge on or near the output side of the conduit. An electrically conducting particle collector outside the conduit is positioned so that a surface is perpendicular or approximately perpendicular to the axis of the funnel. A fan or other blower forces air through the funnel. A power supply imparts an electrostatic potential difference between the electrode, on the one hand, and the holder and particle collector, on the other hand. The electrostatic potential difference produces a corona field in the air in the vicinity of the electrode's sharp tip. The corona field imparts a charge to airborne particles.

    Abstract: An air purifier includes a shell with an air inlet and an air outlet. An electric field filter, an air passage and a blower are disposed inside the shell. The electric field filter includes a filter frame disposed at the air outlet and a grid base disposed under the filter frame. A filter is provided inside the filter frame. One end of the air passage connects with the grid base and the other end connects with the blower. The blower is disposed at the air inlet. The filter frame and the grid base are integrated as a hermetic whole. Due to the integrated configuration of the filter frame and the grid base, when removing out the electric field filter, the power is cut automatically. This effectively prevents an occurrence of the electroshock, and improves safety performance of the purifier. Furthermore, air leakage can be greatly reduced, for there is no gap between the filter frame and the grid base.

  • Patent number: 7651553
    Abstract: The present invention provides a ballast circuit and method for fabricating the same for multi-electrode corona discharge arrays. The circuit includes a conductive plastic material and at least one corona electrode protruding from the conductive plastic material. The distance between the plastic material and the corona electrode varies and controls the electrical resistance and determines the voltage breakdown of the circuit. Additionally, a particle collection surface may preferably be located within the conductive plastic material or preferably be separated from the material depending on the circuit design and configuration.

  • Patent number: 7608135
    Abstract: An air conditioning system includes an air flow pathway extending through a housing from an inlet to an outlet. Air conditioning apparatus is disposed in the airflow pathway between the inlet and the outlet conditioning an air stream passing through the air flow pathway from the inlet to the outlet. A modular electrically stimulated air filter apparatus is carried by opposed, parallel frameworks mounted in series in the air flow pathway between the inlet and the air conditioning apparatus filtering entrapping contaminants in the air stream flowing through the housing from the inlet to the outlet. The opposed parallel frameworks are mounted to opposed supports affixed to the housing.

  • Publication number: 20090235821
    Abstract: A structure for attaching a dust collection electrode of a wet electric dust collector that is low-cost and that is resistant to all of an entire face corrosion, a space corrosion, and a hole corrosion. The structure for attaching a dust collection electrode of a wet electric dust collector is structured so that an end of a dust collection electrode element 3 made of super stainless material is tightened at and is slung to be supported by a slung beam 2 slung in a lateral direction in a building accommodating a dust collection apparatus. A supporting member 5 made of Hastelloy® is attached to the dust collection electrode element 3. The Hastelloy-made supporting member 5 and the slung beam 2 include attachment holes 5a and 2a through which the supporting member 5 and the slung beam 2 are tightened together by tightening means (6, 7).

  • Publication number: 20090120590
    Abstract: A heating system for a spray dryer has a heating element, a heating unit having an open-pore metal foam, and a fluid input and a fluid output. The metal foam is arranged between the fluid input and the fluid output so that fluid which flows in through the fluid input and out through the fluid output is laminarized. A method for simultaneously heating and laminarizing a fluid with the aid of an open-pore metal foam is also disclosed, as is an electrostatic precipitator having a sleeve-shaped electrode connected to a base part of the precipitator. Also disclosed is a device for detaching particles from an inner surface of a sleeve-shaped electrode, a method for detaching particles, and a spray dryer with a heating system as above and/or with an electrostatic precipitator.

  • Patent number: 7517394
    Abstract: A wet electrostatic ionization stage in an electrostatic separation device for purifying a flowing aerosal including finely dispersed particles entrained in a gas. 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.
