Abstract:
An ion generating apparatus prevents a determination that no ions are being generated even when ions are being generated. The ion generating apparatus includes: an ion generator that generates ions; an ion detector that detects generated ions; an air blower that blows the generated ions to an outside through an air supply passage; and a control section that controls driving of the ion generator and the air blower. The control section stops the air blower at a start of operation, performs ion detection using the ion detector, and determines whether ions are being generated. When the control section determines that no ions are being generated, the control section continuously performs a determination of ion generation. When the control section determines that no ions are being generated in all determinations, it is finally determined that no ions are being generated.
Abstract:
Openings 1a and 1a releasing, to the outside, positive and negative ions generated respectively by positive and negative ion generating parts 2 and 3 are formed in different inclined surfaces of a case (an air guiding member) 1 having a regular quadrangular pyramid shape. The positive and the negative ions are released in different directions, and hence recombination of the ions is suppressed. The case 1 guides the air to the openings 1a and 1a from which positive and negative ions are released respectively. The positive and the negative ions released into the guided air flow together with the air flowing, for example, in different directions K3c and K3d. This suppresses recombination of the ions and enhances diffusion of the ions.
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:
An ion-generating device has a positive electrode pair and a negative electrode pair. The positive electrode pair and the negative electrode pair are disposed in a casing with a space interposed therebetween, such that an induction electrode in the positive electrode pair and an induction electrode in the negative electrode pair are separated from each other. It is thereby possible to obtain an ion-generating device and an electrical apparatus, capable of efficiently emitting both of positive ions and negative ions to an outside of the device, and easily achieving reduction in size and thickness.

An air treatment apparatus that includes a housing; a plurality of electrodes, at least one of which receives liquid from a liquid supply; and a power supply. The power supply is operable to establish an electric potential between a portion of the liquid-receiving electrode and the other electrode so that the air treatment apparatus produces a liquid mist having a bipolar distribution of liquid particles.
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. The combined effect of the air flow, electrostatic repulsion from the funnel and electrode, and electrostatic attraction toward the particle collector causes the airborne particles to move toward and then to adhere to the particle collector.
Abstract:
The subject matter relates to devices and methods for dust suppression utilizing an electrostatic dust suppression apparatus which develops an ion cloud containing charged particles for attracting or charging floating dust by bonding to the dust molecules. The particle are introduced through an electrode of the electrostatic dust suppression apparatus which adds an electrostatic charge to the particles as they are dispersed onto an area of fugitive dust. The disbursement of the electrostatic charged particles is accomplished by a pressurized air stream. The electrostatically charged particles attract the fugitive dust and cause the formation of large agglomerates that gravitationally fall to the earth or are electrostatically attracted to the earth.

An air scrubber, system, and method of use are provided. The air scrubber includes an electrospray nozzle for creating an ionic fluid electrospray plume; an air sample intake positioned to provide an air sample interacting with the ionic fluid electrospray plume; and a counter electrode positioned to collect the electrospray plume. The selected chemicals in the air sample are captured by ionic fluid electrospray plume and accumulate on the counter electrode.
Abstract:
An air cleaning device includes a bulb-shaped casing provided at one end with an attached portion to be attached an attaching portion and connected to a commercial power source and at the other end with an outlet, an ozone generator accommodated in the casing and an air supply portion formed in the casing for supplying air into the ozone generator. The ozone generator includes a needle first electrode having a distal end directed to the outlet and a cylindrical second electrode concentric with the first and second electrodes. Application of high voltage between the first and second electrodes induces electrical discharge therebetween, generates negative ions and ozone and releases a stream of air containing the generated negative ions and ozone from the first electrode to the second electrode and outlet.
Abstract:
An oil separator for pressurized systems having flowing vapor with entrained oil particles, the separator including an electrically conducting enclosure having an inlet for the oil bearing vapor and a first outlet for the vapor and a second outlet for the separated oil, an electrically conductive screen positioned within the enclosure to receive the entire flow from said vapor inlet, said screen being electrically insulated from the inlet and enclosure, and a high voltage mono-polarity source connected between the screen and the enclosure. A needle-like electrode at the same potential as the enclosure is positioned at the vapor inlet to accentuate the electric field, thereby improving separation.
