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
