SYSTEM OF REGENERATION OF HYPOXIC GAS ENVIRONMENT WITH A HIGH CONTENT OF ARGON FOR INHABITED SEALED OBJECTS Russian patent published in 2018 - IPC B01D53/00 

FIELD: means of ensuring safety.

SUBSTANCE: invention relates to means for ensuring the habitation and fire safety of submarines, deep-sea inhabited vehicles and other means of developing the world's oceans, autonomous space objects and other hermetic habitable objects. Minimizing the risks of fires and fires in inhabited sealed objects, while providing vital living conditions, by creating and regenerating in these objects a given composition suitable for breathing, hypoxic gas-air media with an increased content of argon is achieved by means of a system for regenerating a hypoxic gas-air medium with an increased content of argon containing mechanically unconnected oxygen and carbon dioxide modules, oxygen module containing an electrolyzer with a solid polymer electrolyte that generates oxygen and hydrogen, pumps that pump water through the gas-liquid lines connecting the cell to the oxygen and hydrogen columns, power supply, control panel, while the carbon dioxide module contains an electric fan that feeds the hypoxic gas-air medium along the gas line to the absorber for purification from carbon dioxide, semisubmersible pump pumping through a rotameter, along a liquid line, a regenerated absorber saturated with carbon dioxide, from the absorber to the stripper, designed to separate carbon dioxide from the liquid regenerable absorber by means of electric heaters, remote control, power supply; argon module, intended for storage and supply of argon gas, containing an automatic ramp with argon cylinders; control unit as part of the oxygen flow regulator, argon flow regulator, discharge electromagnetic valve, pressure sensor and gas mixer; gas control unit with an oxygen gas analyzer operating in a medium with an increased argon content of up to 50 % by volume, with a gas analyzer for carbon dioxide operating in a medium with an increased argon content of up to 50 % by volume, with a gas analyzer for argon with a control range of 0–50 % by volume; automatic control unit; the connection of the oxygen module, the argon module, the carbon dioxide module with the control unit, the carbon dioxide module with the sealed object, and the control unit with the sealed object is carried out with the help of gas lines; while the gas control unit, the control unit, the oxygen module control panel, and the control panel of the carbon dioxide module are electrically connected to the information management control unit.

EFFECT: minimization of risks of fires and fires in inhabited sealed objects while providing vital living conditions.
