The present invention provides methods and systems for a modular ion generator device that includes a bottom portion, two opposed side portions, a front end, a back end, and a top portion. A cavity is formed within the two opposed side portions, front end, back end, and top portion. At least one electrode is positioned within the cavity, and an engagement device is engaged to the front end and/or an engagement device engaged to the back end for allowing one or more modular ion generator devices to be selectively secured to one another.

The generator has three main parts. The first is a charged particle source. The second is a static electric field. The third is a collector connected to the ground or a capacitor. The first species has a wire, the collector, from the ground to the ion source. In the second species, the wire acts as a collector or is attached to the collector. The charged particle source can be any method that can produce ions. The electrostatic field can be the field of the Earth or a static field. The collector is attached to a grounded load. In one design, electrons are drawn through the load by an electron-emitting source attached to the top of the wire. The static electric field causes the rise of the electrons in the wire. In another embodiment, ions from the ion source are accelerated by the static field towards a collector.

A carbon fiber charging device and an electrical appliance therefor are provided. The carbon fiber charging device includes a carbon fiber electrode configured to generate electrons and charge surrounding dust, a protective case configured to cover the carbon fiber electrode such that a foreign object having a size of a human finger is not able to contact the carbon fiber electrode, the protective case including a top wall facing a tip of the carbon fiber electrode and provided with a through hole and a side wall surrounding an outer circumferential surface of the carbon fiber electrode, and an electron generation stabilization device provided in the protective case and configured to allow the carbon fiber electrode to generate electrons stably.

Apparatus for reducing the translucence or opacity caused by smoke within a closed environment includes a fibrous substrate comprising non-conductive fibers. The apparatus further includes elongated, substantially parallel electrodes disposed on the substrate arranged as one or more pairs of adjacent electrodes, wherein a discharge gap is defined between each pair. The apparatus additionally includes a component configured for applying a voltage between each pair to generate a non-thermal microplasma in a corresponding discharge gap to collect or bind one or more airborne particulate combustion byproducts.

Emitter wires and collector pins of current ionic air flow generator designs are replaced by conductors joined to a dielectric substrate, such as metal deposited on the dielectric substrate. One conductor, which is shaped to form the emitter with sharp edges, is joined to one side of the dielectric substrate. Another conductor, which is shaped to form the collector with rounded edges, is joined to the opposite side of the dielectric substrate. The dielectric substrate is not solid. It is shaped with voids that form an air gap between the emitter and the collector. Thus, when a voltage is applied to the emitter, air is ionized at the emitter. The ionized air is drawn electrostatically to the lower-voltage collector, which, through collision with neutral molecules that in turn impart their momentum, creates a flow of air through the air gap.

An improved biogenic ionizer with reduced acoustics and air entrainment is disclosed. The ionizer has a cation and anion generator connectable to a power source and utilizes needle point bipolar ionization to generate anions at a first set of electrodes and cations at a second set of electrodes. The electrodes are located on a first and second side of an air flow separator. The air flow separator is divided into a first air flow path way and a second airflow pathway which are at least partially separated from each other by a divider extending at least partially along the airflow separator. Discharged air through separated passages has a first air stream ionized substantially by cations and a second air stream ionized substantially with anions.

Apparatuses for converting a non-ionized gas stream into an ionized gas stream are disclosed. Disclosed apparatus include an ionizing wire electrode at least partially disposed within and stationary relative to a channel. A frame has plural support elements for supporting the ionizing wire. The frame is configured to make full rotations around the channel in a first rotation direction while applying tension to the ionizing wire. The support elements are configured to physically remove material from the ionizing wire while the support elements are moved along the wire by the frame rotation.
