Abstract

La présente invention concerne un système de purification d'air pour un hôpital d'abri d'urgence temporaire (2). Le système est caractérisé en ce qu'une ouverture d'évacuation d'air (14) est disposée dans une paroi arrière d'un bâtiment où l'hôpital d'abri d'urgence (2) est temporairement établi ; un ventilateur d'évacuation (3) est monté au niveau de la position, à proximité de l'ouverture d'évacuation d'air (14), à l'extérieur du bâtiment ; une conduite d'aspiration d'air (13) est raccordée entre une entrée d'air du ventilateur d'évacuation (3) et l'ouverture d'évacuation d'air (14) du bâtiment ; une conduite d'évacuation d'air (12) est raccordée à une sortie d'air du ventilateur d'évacuation (3) ; et un dispositif de désinfection par atomisation, un dispositif de stérilisation par ultraviolets (11) et un dispositif de condensation à reflux (10) sont montés sur la conduite d'évacuation d'air (12). Lorsque le système est démarré, de l'air à l'intérieur de l'hôpital d'abri (2) s'écoule de force et est évacué du ventilateur d'évacuation (3), et l'air évacué est ensuite mélangé avec un brouillard de médicament du dispositif de désinfection par atomisation, et est désinfecté et purifié par le dispositif de stérilisation par ultraviolets (11), ce qui ne provoque pas de pollution secondaire vis-à-vis de l'air entourant l'hôpital de l'abri (2). La présente invention est faible en termes de coût de construction, facile à assembler et à grande vitesse, de façon à s'adapter à des situations d'urgence lors de pandémies de maladies infectieuses.
