FIELD: technological processes.
SUBSTANCE: device may be used in sealed structures that operate under deficit of fresh air and impossibility of exhaust gases removal from working internal combustion engines, for instance from diesel-generators of civil defense structures during their complete isolation from environment. The device basis is inflatable shell 1, which is separated into several compartments 3, where exhaust gas is injected, which passes previously through gas cooler 15. Shell 1 installed in gallery of structure 7, displaces air from gallery along air duct 30 into diesel generator room 22 during injection of spent gases in gallery, thus normal operation of diesel generator is provided. On completion of complete isolation period, gas is removed from inflatable shell 1 into exhaust ventilation system along air duct 25, and from there - to atmosphere.
EFFECT: provision of high reliability of exhaust gases conservation due to separation of inflatable shell into several compartments.
