Abstract
The present invention relates to an ambient air purifier comprising an electric precipitator having a counter electrode and an emission electrode and is designed to precipitate liquid and/or solid particles from air to be purified while generating ozone, and a catalyst arranged downstream of the electric precipitator in the air flow direction for decomposing at least part of generated ozone.
Claims15
An ambient air purifier (1) comprising:
- an electric precipitator (5) having a counter electrode and an emission electrode and is designed to precipitate liquid and/or solid particles from air to be purified while generating ozone;
- and
- a catalyst (13) arranged downstream of the electric precipitator (5) in the air flow direction for decomposing at least part of generated ozone.
The ambient air purifier (1) according to one of the preceding claims, wherein the catalyst (13) comprises a reticular carrier which is provided with a catalytically active coating, such as a noble metal or manganese dioxide coating.
The ambient air purifier (1) according to one of the preceding claims, further comprising a discharge system (15) arranged downstream of the electric precipitator (5) in the air flow direction and upstream of the catalyst (13) for neutralizing ions generated during electric precipitation.
The ambient air purifier (1) according to one of the preceding claims, wherein the counter electrode is wetted with liquid, in particular washed over with liquid, wherein in particular an at least intermittently moving, in particular continuously flowing, liquid film is formed on the counter electrode.
