Abstract: An electrostatic precipitator using substantially planar screens of similar charge positioned perpendicular to the gas flow direction. The screens have a similar charge of the same polarity, and particles flowing through the screens are charged, agglomerated and either collected on the screens or fall downwardly into collecting hoppers below the screens. The screens preferably have openings smaller than 3 millimeters and are spaced apart less than 10 millimeters. In an alternative embodiment, the screens have alternating polarities and are spaced about an inch or more apart to prevent sparkover.

Abstract: An electrostatic precipitator comprising a corona discharging section for charging dust particles as they pass through and a dust collecting section which has at least two sets of negative plate electrodes for collecting the positively charged dust particles and auxiliary plate electrodes to accelerate the dust particles to the collecting plate electrodes. The collecting and auxiliary plate electrodes in each set are so alternately arranged that the arrangement of the collecting and auxiliary plate electrodes in one set is opposite to that in the adjacent sets whereby the positively charged dust particles passing through the dust collecting section can be effectively collected to the collecting plate electrodes to improve collecting efficiency and energy efficiency with mimized noise.

Abstract: The following is an apparatus and a method that enables the automated collection and identification of airborne particulate matter comprising dust, pollen grains, mold spores, bacterial cells, and soot from a gaseous medium comprising the ambient air. Once ambient air is inducted into the apparatus, aerosol particulates are acquired and imaged under a novel lighting environment that is used to highlight diagnostic features of the acquired airborne particulate matter. Identity determinations of acquired airborne particulate matter are made based on captured images. Abundance quantifications can be made using identity classifications. Raw and summary information are communicated across a data network for review or further analysis by a user. Other than routine maintenance or subsequent analyses, the basic operations of the apparatus may use, but do not require the active participation of a human operator.

Abstract: An electret is disclosed including: a carrier, and polytetrafluoroethylene having a melting point of 35° C. or higher and 320° C. or lower deposited on the carrier, wherein the electret imparts an electrostatic charge to at least one of the carrier and the polytetrafluoroethylene, and has two or more melting point peaks in simultaneous thermogravimetry and differential thermal analysis. An electret filter is disclosed which preferably is used for a filter which requires durability to tobacco smoke. An electret filter is also disclosed having a fluorine-containing component deposited on a fiber surface, wherein an initial QF value is 0.5 mmAq−1 or more in collection efficiency of particles having a particle diameter of 0.3 to 0.5 μm at a wind speed of 5 cm/s, and a filter deterioration rate by tobacco smoke loading is −8/(g/m2) or more.

Abstract: A particle sensor uses an electrostatic particle charging section in the form of an ionization chamber. A flow sensor arrangement is used to produce a signal which is representative of the amount of gas flow between the outside of the ionization chamber and the inside of the ionization chamber. This information is indicative of the flow conditions, and can be used to determine when adverse flow conditions are present which may adversely affect the performance or lifetime of the particle sensor.
