Abstract
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.

A gas ionization apparatus for converting a non-ionized gas stream into an ionized gas stream, the apparatus comprising:
- an ionizing wire electrode at least partially disposed within and stationary relative to a channel;
- and
- a frame having plural support elements for supporting the ionizing wire, the frame configured to make full rotations around the channel in a first rotation direction while applying tension to the ionizing wire, the support elements configured to physically remove material from the ionizing wire while the support elements are moved along the wire by the frame rotation.
A gas ionization apparatus for converting a non-ionized gas stream into an ionized gas stream, the apparatus comprising:
- an ionizing wire electrode at least partially disposed within and stationary relative to a channel;
- and
- a frame having plural support elements for supporting the ionizing wire, the frame configured to rotate around the channel, the support elements being configured to physically clean material off of the surface of the ionizing wire during rotation of each of the support elements of the frame by at least 180 degrees in a single direction.
A gas ionization apparatus for converting a non-ionized gas stream into an ionized gas stream, the apparatus comprising:
- an ionizing wire electrode partially disposed within and stationary relative to a channel, the ionizing wire having a surface that develops a contaminant byproduct in response to production of charge carriers by the ionizing wire in response to provision of an ionizing signal thereto;
- and
- a frame having plural support elements for supporting the ionizing wire, the frame configured to rotate around the channel by at least 180 degrees in a single direction, wherein a first support element of the plural support elements is conductive and electrically isolated from a second support element of the plural support elements, the plural support elements being configured to clean contaminant byproducts off of the surface of the ionizing wire by micro-discharge between the first support element and the ionizing wire during rotation of the frame.
