Title:

GAS TREATING APPARATUS

Document Type and Number:

WIPO Patent Application WO/2005/021160

Kind Code:

A1

Abstract:

A gas treating apparatus for electric precipitation and decomposition of odor by using plasma. A plasma generator (40) is integrally installed in an ionization portion (32) in a casing (20). The ionization portion (32) has an ionization wire (35). A counter electrode (36) is composed of a post-like portion having a U-shaped cross section of a cathode member (37). A plasma generator (40) has an electric discharge electrode (41) and shares the counter electrode (36) with the ionization wire (35). In operating an air cleaner (10), relatively small dust particles in the room air are charged by the electric discharge between the ionization wire (35) and the counter electrode (36) and collected by an electrostatic filter (33). A low-temperature plasma is produced by the streamer electric discharge between the electric discharge electrode (41) and the counter electrode (36), and active species contained in the low-temperature plasma decompose harmful substances and odor substances in the room air.
