Abstract
Description
La présente invention a pour objet un filtre biologique pour l'épurationThe present invention relates to a biological filter for purification
notamment d'air vicié, ainsi que son procédé de fabrication. including stale air, as well as its manufacturing process.
Un tel filtre biologique permet de réaliser une biofiltration qui consiste en un processus de neutralisation des odeurs, utilisé notamment pour neutraliser les mauvaises odeurs. Such a biological filter makes it possible to perform a biofiltration which consists of a process of neutralizing odors, used in particular to neutralize bad odors.
Ce processus est entièrement naturel, l'air à filtrer est acheminé jusqu'à une installation pour être conduit au travers d'un milieu filtrant qui contient des micro-organismes spécifiques, aptes à décomposer les composés odorants. This process is entirely natural, the air to be filtered is conveyed to an installation to be conducted through a filter medium that contains specific microorganisms, able to break down the odorant compounds.
Le milieu filtrant doit présenter certaines caractéristiques pour permettre de retenir les micro-organismes, à cet effet il consiste en un support ou lit constitué d'une matière hydrophile, et qui est régulièrement arrosé d'eau afin de maintenir l'hygrométrie nécessaire. The filtering medium must have certain characteristics to allow the retention of microorganisms, for this purpose it consists of a support or bed consisting of a hydrophilic material, and which is regularly sprinkled with water in order to maintain the necessary hygrometry.
Le support peut être constitué de matériaux divers, de préférence d'origine naturelle, on peut ainsi utiliser soit de la tourbe comme cela est décrit dans le document EP 1.238.697, des écorces d'arbres ou encore des fragments de mésocarpe de noix de coco comme cela est décrit dans le document WO 2004/026438. The support may consist of various materials, preferably of natural origin, it is thus possible to use either peat as described in document EP 1.238.697, tree bark or fragments of walnut mesocarp. coco as described in WO 2004/026438.
De tels filtres sont d'une grande efficacité, ils présentent toutefois un inconvénient, la matière utilisée comme support ou lit est d'une durée de vie limitée, en sorte que selon sa nature elle doit être renouvelée tous les trois ou cinq ans, alors que son coût est relativement important. Such filters are very effective, however, they have a disadvantage, the material used as support or bed has a limited life, so that according to its nature it must be renewed every three or five years, then that its cost is relatively important.
La présente invention a pour but de proposer un filtre biologique permettant de remédier à cet inconvénient. The present invention aims to provide a biological filter to overcome this disadvantage.
Le filtre biologique pour l'épuration notamment d'air vicié selon l'invention, est du type comportant un lit de matière hydrophile apte à être colonisé par des micro-organismes, et il se caractérise en ce que ladite matière hydrophile consiste en des rafles de maïs. The biological filter for the purification of stale air according to the invention is of the type comprising a bed of hydrophilic material capable of being colonized by microorganisms, and it is characterized in that said hydrophilic material consists of stalks of corn.
Outre le fait que les rafles de maïs ont un très grand 35 pouvoir rétenteur d'eau, elles sont d'une longévité très supérieure à celle des autres matériaux naturels utilisés jusqu'à présent. In addition to the fact that corn cobs have a very high water retentive capacity, they are of a much longer life than other natural materials used so far.
La présente demande a également pour objet un procédé de fabrication d'un filtre biologique selon l'invention, lequel procédé se caractérise essentiellement en ce qu'il consiste à cribler puis à nettoyer les rafles de maïs, enfin à disposer lesdites rafles en un lit dans une installation. The present application also relates to a method of manufacturing a biological filter according to the invention, which method is essentially characterized in that it consists in screening and then cleaning the corn cobs, finally to arrange said stalks in a bed in an installation.
Par ailleurs, le prix de revient d'un filtre ainsi constitué est minime puisque la rafle de maïs est à ce jour considérée comme un déchet non valorisable, et disponible en très grandes quantités. Moreover, the cost price of a filter thus constituted is minimal since the corn cob is to date considered a non-recoverable waste, and available in very large quantities.
Les seuls frais liés à l'utilisation des rafles de maïs consistent en des frais de collecte de transport, ainsi que ceux de fabrication du filtre à savoir le criblage et le nettoyage, des rafles. The only costs associated with the use of corn cobs are transportation collection costs, as well as the cost of filtering, namely screening and cleaning, of stalks.
La présente invention permet ainsi de réaliser un filtre biologique meilleur marché que ceux qui existent actuellement, et d'un coût d'entretien inférieur. The present invention thus makes it possible to provide a cheaper biological filter than those which currently exist, and a lower maintenance cost.
