Assignee: ANTON VIKTOROVICH SERGEEV
Field: Medical technology (Instruments)
Classification: CPC A  H | IPC A  H

Claim 0:
1. An air cleaning device comprising:
a high-voltage pulse generator having an output electrode;
an outer electrode shaped as a metal tube; and
an inner electrode that is at least as long as the metal tube, wherein the inner electrode is spaced by a gap from the output electrode of the high-voltage pulse generator, wherein the gap is located outside the metal tube,
wherein the outer electrode is grounded,
wherein the inner electrode is shaped as a metal rod and is rigidly secured along an axis of the metal tube using an auger that is electrically connected to the inner electrode and secured on a portion of the inner electrode inside the outer electrode, wherein a surface of a blade of the auger is formed by a metal strip, and an outer edge of the metal strip is attached to the outer electrode and is electrically insulated from the outer electrode,
wherein the inner and outer electrodes are configured so that pulsed corona discharge streamers are formed in between the inner and outer electrodes, and
wherein a size of the gap assures breakdown of the gap with pulses formed by the high-voltage pulse generator.
