FIELD: devices for cleaning and regeneration of the air in closed airtight rooms; applicable as devices for emergency ventilation in compartments of submarines and pressure chambers. SUBSTANCE: device for emergency ventilation is made of two units:regenerative canister filled with chemical lime absorber and oxygen generator on the solid chemical sources located in strong airtight body. Both units are interconnected through gas injector. Use of gas injector operating on clean oxygen ensures forced ventilation of the room (compartment) with air cleaning from carbon dioxide in canister with chemical lime absorber. EFFECT: higher efficiency. |
