Abstract:
A particle count measurement device includes a preprocessing section configured to place an aerosol introduced into a measurement region in an electrical state of any of a neutralized state, a positively charged state or a negatively charged state, a unipolar charging section inside the measurement region, the unipolar charging section being configured to place the aerosol which has been introduced in either a positively charged state or a negatively charged state that is an electrical state different from at a time of introduction, an ion trap arranged inside the measurement region, on a downstream of the unipolar charging section in terms of a flow of the aerosol, the ion trap including an ion trap electrode for generating an electric field that draws only gas ions in the aerosol, an exhaust mechanism configured to discharge the aerosol from the measurement region at a constant flow rate, and an ammeter for detecting, as a measurement value corresponding to a particle count concentration, a difference between current supplied by the unipolar charging section and current flowing into the ion trap.
Abstract:
Clean corona ionization bars separate contaminant byproducts from corona generated ions by establishing a non-ionized gas stream having a pressure and directed toward an attractive non-ionizing electric field of a charge neutralization target, by establishing a plasma region of ions and contaminant byproducts in which the pressure is sufficiently lower than the pressure of the non-ionized gas stream to prevent byproducts from migrating into the non-ionized gas stream. The ionization bar(s) may be located sufficiently close to the charged neutralization target that a non-ionizing electric field of the target induces at least a substantial portion of the ions to migrate into the non-ionized gas stream and to the neutralization target as a clean ionized gas stream.

Abstract:
The invention relates to an electrostatic filter, comprising a housing having a portion that has an at least approximately circular cross-section for conducting through a particle-carrying gas flow in a longitudinal direction (L) perpendicular to the cross-section. In the housing, a plurality of precipitation plates are arranged, which are oriented in parallel to one another forming channels extending in the longitudinal direction. In each of at least some of the channels, at least one electrode frame (1) having a plurality of elongate electrodes (8) is arranged. Applying a high voltage to the electrodes causes particles carried in the gas flow to deposit on the precipitation plates, wherein the electrodes (8) are immovably fixed only on a supporting member (3) of the electrode frame (1).
Abstract:
There is provided a granular particulate ejector configured to eject granular particulates (a liquid droplet ejector (24) configured to spray liquid droplets (22) ). Granular particulates (liquid droplets (22) ) ejected towards a discharge electrode (21) from the granular particulate ejector (the liquid droplet ejector (24) ) serve as a counter electrode (22).
Abstract:
An air cleaning device (A) includes a bulb-shaped casing (1) provided at one end with a base (4) and at the other end with an outlet (3e, 3a), in which an AC/DC converter (11) for converting an alternating current from the base (4) into a direct current, a boosting transformer (12) for boosting the direct current, and a negative ion generator or ozone generator (21 or 21A) connected to the boosting transformer (12) are accommodated. Application of high voltage from the boosting transformer (12) to the negative ion generator or ozone generator (21 or 21A) induces electrical discharge to generate negative ions alone or both negative ions and ozone and release the negative ions alone or both the negative ions and the ozone from the outlet (3e, 3a). The device can be disposed on the floor, suspended from above, hung on the wall or set in position at an optional location, using as its power source electric power from a socket (41A, 41B) for a reading lamp, a socket (62) built in the ceiling, or an electrical receptacle mounted in a wall, so that negative ions alone or both negative ions and ozone can be released in an optional direction.
