Title:
AIR SANITATION DEVICE BY EMISSION OF A BARRIER OF ULTRAVIOLET RADIATION IN AN AIR FLOW
Document Type and Number:
WIPO Patent Application WO/2022/144821
Kind Code:
A8
Abstract:
Device (1) intended for air sanitation in circumscribed environments by generating a sterilising barrier substantially consisting of superimposing a descending vertical laminar air flow (33) and a peripherally delimited ultraviolet radiation beam (22) also directed downwards. The device (1), of simplified design and small size, comprises means (30) for delivering a vertical laminar air flow at a controlled and humidified temperature, as well as, adjacent to such delivery means (30), one or more sources (20) for the external emission of an ultraviolet radiation beam of a wavelength appropriately chosen to offer a high germicidal action and not constitute a risk for humans. Therefore, such a substantially superimposed air flow (33) and ultraviolet radiation beam (22) form a barrier with high sterilising power and capable of generating confined areas. Therefore, the device (1) thus conceived is suitable for installation in circumscribed environments, typically crowded, in which the transmission of pathogens and, consequently, the risk of contagion is to be reduced. It is particularly applicable in public places such as offices, restaurants, public establishments of various kinds as well as transport means.
