Regenerative canister of a self-contained oxygen-breathing apparatus on chemically fixed oxygen

摘要

A regenerative canister of a self-contained oxygen-breathing apparatus, comprising a shell filled with an oxygen-delivering chemical, wherein heat-distributing elements are accommodated. A number of transverse air-permeable partitions are installed in the shell central portion to subdivide the shell interior into two compartments and to form a distributing chamber. Each of the compartments is provided with additional partitions that divide the oxygen-delivering chemical into at least two layers, while the heat-distributing elements are located on the section running from the distributing chamber to the layer of the oxygen-delivering chemical adjacent to the shell end.
