Definitions
- PROCESS FOR THE PRODUCTION OF OXYGEN BY A PORTABLE APPARATUS, PARTICULARLY FOR HUMAN RESPIRATI O N A N D APPAR A TUS TO CARRY OUT THE PROCESS
- the present invention relates to a process for the production of oxygen by a portable apparatus, particularly for human respiration and an apparatus to carry out the process. It is known that it is possible to obtain oxygen
- the sodium percarbonate powder is poured into a vessel with water and subsequently the MnO. powder is poured starting the reaction.
- this reaction is strongly exothermic, it releases oxygen at high temperature and changes part of the water into steam, providing a mixture of
- reaction rate of sodium percarbonate it has also been proposed to differ the dissolution of the catalyst
- An aim of the invention is to avoid such drawbacks
- An other aim of the invention is to realize a
- sodium perborate can be used in a weight ratio of 1:1 - 1:2,
- salts such a Fe, Cu, Pb, etc. can be used.
- Figure 2 shows in vertical-longitudinal section a portable
- the water has the function of dissolving the components of the mixture and at the same time partially
- sodium perborate is between 1 :1 and 1:2, preferably
- the catalyst is preferably of the MnO , but in its
- metal salts such as Fe, Cu, Pb, etc. could be advantageously used.
- the sodium perborate which, as the sodium percarbonate, participates in the decomposition reaction has the essential function of reducing the decomposition
- reaction are thence made pass through an heat exchanger 2 in which the cooling of the oxygen and the partial condensation
- the lid 6 is provided with a gasket 7 which completely seals the external perimeter of the three containers 1, 2, 3 beside sealing the internal wall between the heat exchanger 2 and
- baffle 8 is provided in parallel to the walls of the overflow interspace 3.
- the other end section 12 of the coil 10 extends
- lid 6 which is of a
- the gaseous flow of oxygen and steam has passed from the reactor 1 to the overflow interspace 3 through the o upper connection leak and the labyrinth 5 which has provided to a first crack-down of solid elements in suspension as
- produced oxygen flow can be varied, according to the user's

Abstract
On fait réagir un mélange de percarbonate de sodium et de perborate de sodium en présence d'un catalyseur approprié et d'eau à l'intérieur d'une cuve étanche (1) suivant la réaction 2Na2CO3. 3H2O2+ NaBO2.H2O2$(1,8)$Na2CO3+ NaBO2+ 4H2O + 2O2 et on fait passer l'oxygène gazeux et la vapeur saturée résultant de la réaction à travers un échangeur thermique (2) qui les refroidit et les déshumidifie.
