Abstract
Description
Dispositif pour la diffusion atmosphérique de produits
actifs en phase gazeuse
Il est connu de diffuser dans l'atmosphère des produits désinfectants, désodorisants, insecticides, parfumants, bactéricides, bactériostatiques, absorbants de fumée, curatifs ou autres, dissous dans un liquide combustible, par combustion catalytique de ce liquide.Device for the atmospheric diffusion of products
active in gas phase
It is known to diffuse into the atmosphere disinfectants, deodorants, insecticides, perfumers, bactericides, bacteriostats, smoke absorbers, curatives or others, dissolved in a combustible liquid, by catalytic combustion of this liquid.
Mais la combustion catalytique de la solution porte les produits actifs a une température élevée qui peut ut de 1 ordre de 3009, et il est difficile de trouver des produits actifs qui résistent sans dommage a cette température. However, the catalytic combustion of the solution brings the active products to a high temperature which can be of the order of 3009, and it is difficult to find active products which withstand this temperature without damage.
La demanderesse a décrit dans son brevet français 80 12711 un dispositif remédiant en partie a cet inconvénient et compre- nant un brûleur formé d'un système de de mèche dent l'extrémité su prieure se trouve a proximité d'une pastille catalytique et dont une partie est engagée dans un trou de la pastille cylin- drique, en étant séparée de la paroi de cette pastille par une chemise en une matière non catalytique. The Applicant has described in its French patent 80 12711 a device partially remedying this drawback and comprising a burner formed by a wick system, the upper end is located near a catalytic tablet and one of which part is engaged in a hole in the cylindrical pellet, being separated from the wall of this pellet by a jacket made of a non-catalytic material.
Lors de l'utilisation du dispositif la partie de la solu- tion qui arrive, par 1 'intermédiaire de la partie centrale du système de mèche, au centre de la pacotille est a simplement chauf- fée par la chemise qui entoure la mêche et est elle-même chauf- fée par la pastille. Elle est donc portée a une température net- tement inférieure a la température de combustion catalytique. When using the device, the part of the solution which arrives, through the central part of the wicking system, at the center of the junk is simply heated by the jacket which surrounds the wick and is itself heated by the pellet. It is therefore brought to a temperature significantly lower than the catalytic combustion temperature.
Mais l'expérience montre que cette température paut cependant être encore trop élevée pour certains produits fragiles; par ailleurs, il est impossible avec ce dispositif de diffuser dans l'atmosphère des produits actifs qui sont incompatibles avec le liquide servant d la combustion, comme c' est souvent le cas pour les parfums et les produits insecticides. However, experience shows that this temperature may still be too high for certain fragile products; moreover, it is impossible with this device to diffuse into the atmosphere active products which are incompatible with the liquid used for combustion, as is often the case for perfumes and insecticide products.
La présente invention a pour objet un dispositif a combus- tion catalytique gui pallie ces inconvénients. The subject of the present invention is a catalytic combustion device which overcomes these drawbacks.
Ce dispositif comprend un brûleur formé d'une mêche dont l'extrémité supérieure se trouve à proximité d'une pastille cata- lytique et est caractérisé en ce qu'un réceptacle pour le produit actif est disposé autour de la pastille catalytique4
Lors de l'utilisation du dispositif, le réceptacle est chauffé par le rayonnement de la pastille ou du capuchon de protection qui la recouvre éventuellement, ainsi que, par con- ductibilité, par le support de la pastille et du réceptacle.This device comprises a burner formed from a wick, the upper end of which is near a catalytic tablet and is characterized in that a receptacle for the active product is placed around the catalytic tablet4
When the device is used, the receptacle is heated by the radiation of the patch or of the protective cap which optionally covers it, as well as, by conductibility, by the support of the patch and of the receptacle.
Comme il n'y a qu'une faible partie des calories dégagées par la combustion catalytique, qui parvient au réceptacle, le pro duit actif qu'il contient est relativement peu chauffé et porté à une température voisine de 400, ce qui évite toute détériora- tion du produit. Par ailleurs, le produit n'étant pas mélangé avec le liquide servant à la combustion, n'est pas détérioré par ce liquide et est diffusé dans son intégralité physico-chimique. As there is only a small part of the calories released by catalytic combustion, which reaches the receptacle, the active product which it contains is relatively little heated and brought to a temperature close to 400, which avoids any deterioration. - tion of the product. Furthermore, the product not being mixed with the liquid used for combustion, is not deteriorated by this liquid and is diffused in its entire physico-chemical content.
Le produit actif peut être constitué par un liquide qu'on verse dans le réceptacle. Mais il peut aussi imprégner une couronne en matière solide spongieuse qu'on place dans ce récepta cle. The active product can consist of a liquid which is poured into the receptacle. But it can also impregnate a crown of spongy solid material that is placed in this key receptacle.
On a décrit ci-après, à titre d'exemple non limitatif, un mode de réalisation du dispositif de diffusion perfectionné selon la présente invention, avec référence à la figure unique du dessin annexé qui représente ce dispositif, partie en élévation et partie en coupe. An embodiment of the improved diffusion device according to the present invention has been described below, by way of non-limiting example, with reference to the single figure of the appended drawing which represents this device, part in elevation and part in section. .
Le dispositif selon l'invention comprend une mêche 1 dont l'extrémité supérieure est engagée dans un support 2, celui-ci est prolongé vers le haut par des griffes 3 enserrant une pastille catalytique 4 composée de matières inertes auxquelles est adjoint un catalyseur tel que, par exemple, du platine ; la partie périphérique la de la mêche 1 est appliquée sous la pas- tille 4. Celle-ci est percée en son centre d'un trou dans lequel est engagée une chemise 5 s'étendant jusqu'à la mêche 1 et ne contenant pas de catalyseur. La partie centrale lb de la moche 1 est engagée dans la chemise 5. The device according to the invention comprises a wick 1, the upper end of which is engaged in a support 2, which is extended upwards by claws 3 enclosing a catalytic tablet 4 composed of inert materials to which is added a catalyst such as , for example, platinum; the peripheral part 1a of the wick 1 is applied under the pad 4. The latter is pierced in its center with a hole in which is engaged a jacket 5 extending to the wick 1 and not containing catalyst. The central part 1b of the ugly 1 is engaged in the jacket 5.
L'ensemble est disposé dans un récipient 7 contenant une solution combustible 8, par exemple de l'alcool éthylique ou isopropylique, le récipient 7 est coiffé par un couvercle 9 dont la partie centrale 9a est tronconique et évidée et sur lequel repose le support 2. The assembly is placed in a container 7 containing a combustible solution 8, for example ethyl or isopropyl alcohol, the container 7 is capped by a cover 9 whose central part 9a is frustoconical and hollowed out and on which the support 2 rests .
La référence 10 désigne un capuchon de protection ajouré qui recouvre le brûleur et est emmanché sur la partie centrale tronconique 9a du couvercle 9. La chemise 5 transmet la partie centrale lb de la miche, par conductibilité, une certaine fraction des calories fournies par la combustion catalytique de la solution 8. La solution qui est amenée par capillarité la partie lb de la mèche, s'évapore et se disperse dans l'atmosphère. The reference 10 designates a perforated protective cap which covers the burner and is fitted on the frustoconical central part 9a of the cover 9. The jacket 5 transmits the central part lb of the loaf, by conductivity, a certain fraction of the calories supplied by combustion catalytic solution 8. The solution which is brought by capillary action part lb of the wick, evaporates and disperses in the atmosphere.
Mais l'expérience montre que la solution amenée à la partie lb de la mèche, est portée à une température de l'ordre de 1000 C, malgré l'isolement thermique assuré par-la chemise 5. However, experience shows that the solution brought to the part 1b of the wick, is brought to a temperature of the order of 1000 C, despite the thermal insulation provided by the jacket 5.
Cette température est parfois trop élevée pour certains adjuvants dont certains sont par ailleurs incompatibles avec le liquide servant à la combustion.This temperature is sometimes too high for certain additives, some of which are also incompatible with the liquid used for combustion.
Pour résoudre ce problème, le dispositif comporte pour l'adjuvant un réceptacle particulier 11 qui repose sur le couvercle 9 et entoure la base du capuchon 10. Dans l'exemple représenté, l'adjuvant imprègne une couronne 12, en une matière solide spongieuse, qui est logée dans le réceptacle 11. Une partie des calories développées par la combustion catalytique de la solution 8 est transmise au réceptacle 11 par rayonnement par le capuchon 10 et par conductibilité par le couvercle 9. To solve this problem, the device comprises for the adjuvant a special receptacle 11 which rests on the cover 9 and surrounds the base of the cap 10. In the example shown, the adjuvant permeates a crown 12, made of a spongy solid material, which is housed in the receptacle 11. A portion of the calories developed by the catalytic combustion of the solution 8 is transmitted to the receptacle 11 by radiation by the cap 10 and by conductivity by the cover 9.
La couronne 12 est ainsi portée à une température de l'ordre de 40 à 500 C qui évite la destruction des molécules fragiles.The crown 12 is thus brought to a temperature of the order of 40 to 500 ° C. which avoids the destruction of the fragile molecules.
va va de soi que la présente invention ne doit pas 8trie considérée comme limitée, au mode de réalisation décrit et représenté, mais en couvre, au contraire, toutes les variantes. It goes without saying that the present invention should not be considered as limited to the embodiment described and shown, but on the contrary covers all variants thereof.
