Abstract
An in-duct apparatus for sanitizing air includes a reaction unit, configured to be mounted in an air duct, for generating reactive oxygen species from oxygen in air received in the reaction unit to be sanitized. Airborne contaminants in the received air are substantially neutralized by the generated reactive oxygen species before the air is discharged from the reaction unit.
Claims4
A system, comprising:
- an air duct;
- a reaction unit disposed within the air duct, said reaction unit configured to generate ozone and reactive oxygen species from oxygen in air received in the reaction unit to be sanitized;
- and
- a vortex disposed downstream from and spaced apart from an output end of said reaction unit, said vortex configured to mix an output from said reaction unit with air in the air duct, said vortex comprising:
- an input opening, configured to increase airflow speed entering said vortex, said input opening comprising:
- an exterior portion, configured to receive air entering said vortex;
- an interior portion, said interior portion having a height and a width each smaller than a height and a width of the exterior portion;
- and
- a tapered body portion disposed between the exterior portion and the interior portion;
- an output opening, configured to increase airflow speed exiting said vortex, said output opening comprising:
- an interior portion;
- an exterior portion configured to release air from said vortex, said exterior portion having a height and a width each smaller than a height and a width of the interior portion;
- and
- a tapered body portion disposed between the exterior portion and the interior portion;
- a first row of plates disposed between said input opening and said output opening, said first row of plates comprising a plurality of perforated airflow mixing plates disposed at an angle such that said plurality of perforated airflow mixing plates create a V-shaped member;
- and
- a second row of plates disposed downstream from said first row of plates, said second row of plates comprising:
- a plurality of perforated airflow mixing plates;
- and
- a plurality of solid back flow plates,
- wherein said second of plates are positioned in an alternating angled arrangement with said plurality of perforated airflow mixing plates positioned in a center of said second row of plates and said plurality of solid back flow plates positioned at ends of the second row of plates.
