Abstract
Le réacteur pour la purification d'un fluide gazeux ou liquide, comporte une enceinte (1) comportant : i) en partie inférieure un conduit d'entrée (10) dudit fluide et en partie supérieure un conduit de sortie (20) dudit fluide, ii) entre lesdits conduits, une chambre interne (2) contenant une quantité de média photocatalytique (100) selon la revendication 13, la cloison inférieure de la chambre étant constituée d'un filtre (3) apte à retenir les particules dudit media et à laisser circuler ledit fluide, et iii) une lampe (4) émettrice de rayons UV, s'étendant dans ladite chambre à proximité dudit média, entre les conduits d'entrée (10) et de sortie (20) du fluide, de sorte que le média photocatalytique constitue un lit fluidisé éclairé par la lampe (4), qui est apte à purifier ledit fluide lorsque celui-ci traverse le réacteur.The reactor for the purification of a gaseous or liquid fluid comprises an enclosure (1) comprising: i) in the lower part an inlet conduit (10) of said fluid and in the upper part an outlet conduit (20) of said fluid, ii) between said ducts, an internal chamber (2) containing a quantity of photocatalytic medium (100) according to claim 13, the lower partition of the chamber consisting of a filter (3) able to retain the particles of said medium and to allowing said fluid to circulate, and iii) a lamp (4) emitting UV rays, extending in said chamber close to said medium, between the fluid inlet (10) and outlet (20) ducts, so that the photocatalytic medium constitutes a fluidized bed illuminated by the lamp (4), which is capable of purifying said fluid when the latter passes through the reactor.
