Description

ProcAde de preparation d'un produit granule pour generateur d'ogygene. L'emploi des peroxydes alcalins actives au moyen d'un catalyseur tel que 1'oxyde de cuivre, 1e Sulfate de cuivre ou autres produits equivalents presente 1'inconvenient, lorsque ces oxydes sont utilises comme regenerateurs d'air vioie par la respiration, de se colma- ter principalement sous 1'action de Panhy- dride carbonique; il en resulte un fonetion- nement defectueux, un mauvais rendement et un danger par Suite de Pobstruction des ap- pareils respiratoires. Process for preparing a granular product for an oxygen generator. The use of alkaline peroxides activated by means of a catalyst such as copper oxide, copper sulphate or other equivalent products has the disadvantage, when these oxides are used as regenerators of air violated by respiration, of to clog mainly under the action of carbon dioxide; the result is faulty operation, poor performance and danger due to obstruction of the breathing apparatus.

Ce fait provient de ce que .ces peroxydes alcalins apres reaetion sous 1'action du cata- lyseur avec 1'humidite et 1'anhydride carbo- iiique provenant de la respiration, laissent un residu de carbonate de soude ou de potasse qui forment une croüte colmatee Sur les peroxydes alcalins, arretant toute reaction et par Suite tout degagement d'oxygene. This fact arises from the fact that these alkaline peroxides, after reacting under the action of the catalyst with the humidity and the carbon dioxide coming from respiration, leave a residue of carbonate of soda or potash which forms a crust. clogged On alkaline peroxides, stopping any reaction and consequently any release of oxygen.

La presente invention permet de reme- dier aux inconvenients ei-dessus; eile se rap- porte ä un procede de preparation d'un pro- duit granule pour generateurs, d'oxygene, caracterise en ce que Von melange une sub- stance pulverulente apte ä degager de 1'oxy- gene par reaction avec de 1'eau, un catalyseur accelerant cette reaction et de la Paraffine finement räpee, et soumet 1e tout ä 1'action dune machine ä granuler. The present invention makes it possible to remedy the above drawbacks; it relates to a process for the preparation of a granular product for oxygen generators, characterized in that a powdery substance capable of releasing oxygen by reaction with 1 water, a catalyst accelerating this reaction and finely grated paraffin, and submits the whole to the action of a pelleting machine.

0n peut, par exemple, melanger un Peroxyde alcalin pulverulent, dune Part, avec un catalyseur tel que de 1'oxyde ou du Sulfate de cuivre et, d'autre Part, avec une Paraffine dopt 1e point de fusion est com- pris entre 35 et 40 , cette derniere etant fine- ment räpee; puis 1e tout est introduit dans une macbine ä granuler. One can, for example, mix a pulverulent alkaline peroxide, on the one hand, with a catalyst such as copper oxide or sulphate and, on the other hand, with a paraffin whose melting point is between 35 and 40 , the latter being finely grated; then the whole is introduced into a granulating machine.

Les granules ainsi obtenus reagissent de la fagon suivante: Sous 1'action de 1'humidite et de 1'anhy- dride carbonique provenant de la respiration, ou simplement sous 1'action de Peau, les par- ticules en surface de 1'agglomerä commencent ä reagir en degageant de 1'oxygene, la Pa raffine empechant la formation de croütes de carbonate, et permettant ainsi un contact constant de 1'humidite avec les particules des peroxydes alcalins actives. A ihre d'exemple, 1e produit destine ä eire granule peut etre obtenu en melangeant 72 Parties en poids de Peroxyde de sodium (Na202) et 3 Parties en poids de Sulfate de cuivre ou d'oxyde de cuivre, avec 25 Parties en poids de Paraffine; dans ce melange, 1e Peroxyde de sodium peut etre remplace soit par du trioxyde de potassium et de sodium (KNa03), soit par du pentoxyde de potas- sium et de sodium (K'NaO'). The granules thus obtained react in the following way: Under the action of humidity and carbon dioxide from respiration, or simply under the action of water, the particles on the surface of the agglomerate begin to react by releasing oxygen, the raffine preventing the formation of carbonate crusts, and thus allowing constant contact of moisture with the particles of the active alkali peroxides. By way of example, the product intended for the first granule can be obtained by mixing 72 parts by weight of sodium peroxide (Na202) and 3 parts by weight of copper sulphate or copper oxide, with 25 parts by weight of Paraffin; in this mixture, the sodium peroxide can be replaced either by sodium potassium trioxide (KNaO3) or by sodium potassium pentoxide (K'NaO').
