Abstract

The dryer has a frame (1) for supporting media (2) that includes an active coal side and an enlaced side, where the enlaced side comprises titanium dioxide deposit. The media modifies organic elements under the action of an UV source (3). A ventilation system (4) forces air through an assembly of the dryer and heats the air using a heating system (5). The ventilation system and the heating system are provided in a case (6).

Description

-1- SECHEUR AVEC PHOTO CATALYSE Domaine technique de l'invention. -1- DRYER WITH PHOTO CATALYSIS Technical field of the invention.

La présente invention concerne un dispositif de traitement et de purification d'air par photo catalyse traversant et léchant associé à un sécheur. The present invention relates to a device for the treatment and purification of air by photo-crossing and licking catalyst associated with a dryer.

État de la technique antérieure. State of the art

io Dans les appareils connus qui réalisent du séchage, on ne gère pas l'environnement organique. Ce qui à pour effet d'extraire des éléments organiques nocifs ou d'importer des éléments organique tout aussi nocifs et de les déposer sur les éléments à sécher. In known apparatuses which perform drying, the organic environment is not managed. This has the effect of extracting harmful organic elements or importing equally harmful organic elements and depositing them on the elements to be dried.

15 En effet une concentration importante d'éléments organiques, germes, virus, bactéries, COV, etc. sont présents dans l'air et dans les appareils de séchage, ces éléments organiques sont transférés directement sur les élément à sécher que ce soit du linge, les mains, les cheveux etc. pour des appareils domestiques ou que ce soit du textile, des graines, de la volaille, des plumes etc. Ce phénomène rend très 20 critiquable l'utilisation de ce type d'appareil. Indeed, a high concentration of organic elements, germs, viruses, bacteria, VOCs, etc. are present in the air and in the drying apparatus, these organic elements are transferred directly to the elements to be dried whether it be linen, hands, hair, etc. for household appliances or whether textile, seeds, poultry, feathers etc. This phenomenon makes the use of this type of apparatus very objectionable.

Pour lutter contre ce phénomène l'idée est d'assainir l'air entrant et sortant de l'appareil. Pour ce faire l'idée est d' y adjoindre un procédé de traitement d'air de type photo catalyse afin de traiter l'air traversant les appareils. Objet de l'invention. To fight against this phenomenon the idea is to clean the air coming in and out of the device. To do this the idea is to add a photo catalysis type air treatment process to treat the air passing through the devices. Object of the invention

La présente invention a pour but de remédier à ces inconvénients. The present invention aims to overcome these disadvantages.

30 A cet effet, on a imaginé un dispositif par l'association d'un sécheur et d'un dispositif de traitement d'air par photo catalyse, un média comprenant une face de charbon actif et une face tressée sur laquelle est déposé du dioxyde de titane (TiO2), ce média étant exposé à une source ultra violet (UVA ou UVC) ce qui à pour effet de détruire tous les éléments organiques traversant l'ensemble. 25 5 -2- Un système de ventilation force l'air à traverser l'ensemble photo catalyse et sécheur muni éventuellement d'un système de chauffage For this purpose, a device has been devised by the combination of a dryer and an air-treatment device by photo-catalysis, a medium comprising an active carbon face and a braided face on which is deposited carbon dioxide. titanium (TiO2), this medium is exposed to an ultra violet source (UVA or UVC) which has the effect of destroying all the organic elements passing through the assembly. A ventilation system forces the air to pass through the photo-catalytic and dryer assembly possibly equipped with a heating system.
