CHEMICAL OXYGEN GENERATOR Russian patent published in 2007 - IPC C01B13/02 A62B7/08 B01J7/00 

FIELD: chemical industry; aircraft industry; shipbuilding industry; space industry; fire-protection; care of public health; devices for production of oxygen.

SUBSTANCE: the invention may be used for production of the cooled oxygen for breathing of the people in the emergency situations in the airplanes, the submarines, the space stations, at fires. The chemical oxygen generator contains the charge case and located in it the porous gas-permeable mechanically strong charge. The charge is made out of the mixture emitting the oxygen at the exothermal self-supporting decomposition after its initiation and contains of no more than 3 mass % of the binding agent. The charge ensures the possibility for the oxygen to pass through without damaging the non-treated material and without its volumetric volume burning. The produced oxygen passes through the charge under action of the difference of the pressures from the front of the decomposition moving in the direction to the outlet opening. The oxygen generator also contains the device for ignition and one or more the outlet openings for the produced oxygen coming out, the filters for its cooling, for prevention of the particles of corpuscles and contaminants carry-over, and also the filter with the catalyst for conversion of the produced at decomposition of CO₂ into CO.

EFFECT: the invention ensures the possibility for the oxygen to pass through the charge without damaging the non-treated material and without its volumetric volume burning.
