Description
<Desc/Clms Page number 1> "Filtre pour résorption et adsorption de gaz; vapeurs, odeurs et analogues" L'invention concerne un filtre pour la résorption ot adsorption de gaz, vapeurs, odeurs et mélangea toxiques de l'air respiré. L'invention doit notamment rendre non toxi- ques les mélanges de gaz de fumées incomplètement brûlés, échappés des moteurs à combustion, des turbines à gaz, des moteurs Diesel et supprimer les mauvaises odeurs des armoi- res de réfrigération, des toilettes, des chambres enfumées ou remplies de gaz. On utilise déjà pour cela des cartouches de mas- ques à gaz ou des récipients, qui ne peuvent être utilisée qu'une seule fois. On a utilisé pour cela des filtres à charbon très <Desc/Clms Page number 2> poreux avec des cartouches filtrante $ qui doivent être régén rées assez souvent d'une façon assez compliquée, L'invention a notamment pour objet un filtre pour résorption et adsorption de gaz, fumée., vapeurs, odeurs on ana- logues filtre caractérisé par des corps organiques, mousses EMI2.1 hydrophiles à cellules ouvertes, servant de substance de support pour des groupes oxydants-réducteurs agissant par catalyse, Il a été constaté en effet que des corps organi- ques, mousses hydrophiles à cellules ouvertes, conviennent bien à cause de leur grande capacité d'absorber ou de retenir de EMI2.2 l'eau spécialement comme 81betanCI' de support de troupes d4or- dation et de réduction qui agissent par ottalystè Si, en présen- ce de potaese, on emploie comme catalyseur par exemple u milan EMI2.3 ge d' oxyde de ou.ivre '. oxyndrate de manganèse - oxyde de fort on dispose d'une combinaison rédactrice-oxydante qui transforme, à la température ordinaire, avec l'aide de l'oxygène de l'air les substances toxiques en substances non toxiques, le plus souvent sans odeur. conformément à l'invention, on peut employer aoame substances de support des mousses de polyuréthane linéai- res on en ohatne auxquelles on additionne des catalyseurs ou EMI2.4 d'autres agents de réaction. Oomme système de réduot3on-oxrda- tion, on peut, conformément à l'invention, employer des composée facilement oxydables et réductible% comme les oxydes de cuivre, les oxydes de manganèse en présence de carbonate de potassium, les oxydes d'argent, les oxydes de fer, et des composée organi- EMI2.5 que. également eit'iaroea, Pour former des moussa plastiques uniforme à EMI2.6 cellules ouvertes, on emploie avantageusement l'hydrosilioate d'aluminium.

Le bloc de mousse élastique fini est découpé encore chaud en plaques, et placé dans l'eau. Après u lavage d'une heure à l'eau alcaline, les plaques sont essorées en les faisant passer entre des cylindres en caoutchouc, et elles sont prêtée à être utilisées. Quand on utilise ces plaquée, il faut toujours veiller à ce que la plaque mousse se remplies* toujours quand elle est encore humide. On peut la laver aveo du savon et de l'eau, et elle se régénère toujours elle-même, EXEMPLE 2 1000 parties d'un mélange polymère de chlorure et acétate de polyvinyl sont broyées avec: EMI3.6 460 parties de d100tylphtalate EMI3.7 200 " de ptrdn3l éther d'oxyde gras d'tl!tyjLpolyprepylèa< EMI3.8 <tb> 50 <SEP> de <SEP> bioxyde <SEP> de <SEP> manganèse <tb> <Desc/Clms Page number 4> EMI4.1 <tb> 30 <SEP> " <SEP> de <SEP> monoxyd <SEP> de <SEP> cuivre <tb> <tb> 15 <SEP> " <SEP> d'oxyde <SEP> de <SEP> oobalt <tb> <tb> 5 <SEP> d'oxyde <SEP> d'argent <tb> <tb> 200 <SEP> " <SEP> de <SEP> silicate <SEP> d'aluminium <SEP> on <SEP> Bentonite <SEP> active <tb> et saturées à 50/atm dans un récipient de pression avec de l'acide carbonique et de l'azote.
