Title
(EN) AIRBORNE MICROORGANISMS NEUTRALIZING SYSTEM AND METHOD OF NEUTRALIZING AIRBONE MICROORGANISM
(FR) SYSTÈME ET PROCÉDÉ DE NEUTRALISATION DE MICROORGANISMES EN SUSPENSION DANS L'AIR
Abstract
(EN)
A system for neutralizing airborne microorganisms includes a conditioning section for accommodating a flow of air, the conditioning section including an air inlet; an air outlet;a packing chamber located downstream relative to the air inlet, a distribution chamber located downstream relative to the packing chamber and located above the packing chamber, the distribution chamber including at least one spray nozzle for spraying a liquid desiccant into the distribution chamber towards the packing chamber; a sump located below the packing chamber; a pump for propelling the liquid desiccant from the sump to the at least one spray nozzle; a droplet collection chamber located downstream relative to the at least one spray nozzle for removing droplets from the flow of air flowing through the droplet collection chamber; and a UV disinfection chamber located downstream relative to the droplet collection chamber and upstream relative to the air outlet.
(FR)
L'invention concerne un système pour neutraliser des microorganismes en suspension dans l'air comprenant : une section de conditionnement pour recevoir un flux d'air, la section de conditionnement comportant une entrée d'air ; une sortie d'air ; une boîte à garniture située en aval par rapport à l'entrée d'air, une chambre de distribution située en aval par rapport à la boîte à garniture et située au-dessus de celle-ci, la chambre de distribution comprenant au moins une buse de pulvérisation servant à pulvériser un déshydratant liquide provenant de la chambre de distribution vers la boîte à garniture ; un puisard situé au-dessous de la boîte à garniture ; une pompe servant à propulser le déshydratant liquide du puisard vers la ou les buses de pulvérisation ; une chambre de collecte de gouttelettes située en aval par rapport à au moins une buse de pulvérisation servant à éliminer les gouttelettes du flux d'air traversant la chambre de collecte de gouttelettes ; et une chambre de désinfection UV située en aval par rapport à la chambre de collecte de gouttelettes et en amont par rapport à la sortie d'air.
