Device and method for removing undesirable gases and particles from the air
View Patent ↗A device and a method for removing undesirable gases and particles from the air are provided. The device includes a purifying chamber through which air ( 1 ) to be purified is arranged to pass and has an entrance end provided with a zone ( 2 ) producing water dust. The purifying chamber is provided with ionemitting tips ( 3 ) operating by high voltage current and with collecting surfaces ( 4 ) collecting impurities from the air. The zone ( 2 ) is provided with dies ( 7 ) producing water dust having a droplet size of 20 to 40 μm, and the collecting surfaces ( 4 ) are grounded. The ion emitting tips ( 3 ) are directed toward the collecting surfaces ( 4 ) and generate ion jets rushing from the ion emitting tips ( 3 ) causing water dust and gases and particulate materials attached to the droplets of said dust to be forced against said collecting surfaces ( 4 ).
1. A device for removing undesirable gases and particles from the air,
wherein the device comprises a purifying chamber through which air to be purified is arranged to pass and having an entrance end provided with a zone producing water dust,
wherein said purifying chamber being provided with ion emitting tips operating by high voltage current at a range of 5 to 150 kV and with collecting surfaces collecting impurities from the air,
wherein said zone is provided with dies producing water dust having a droplet size of 20 to 40 μm, and that said collecting surfaces are grounded and that the ion emitting tips are directed towards said collecting surfaces and generate ion jets rushing from the ion emitting tips causing water dust and gases and particulate materials attached to the droplets of said dust to be forced against said collecting surfaces.
2. The device according to claim 1 , wherein there is an outlet chamber at the bottom of the purifying chamber for conveying gases and particles separated from the air together with water formed from the water dust away through the entrance end of the purifying chamber.
3. The device according to claim 2 , wherein water dust is produced by means of an ultrasound-oscillator.
4. The device according to claim 2 , wherein water dust is produced with compressor-pressurized air.
