UNDERWATER VEHICLE INTERNAL ASSEMBLY FITTED WITH A SYSTEM FOR TREATING AMBIENT GAS AND ASSOCIATED TREATMENT METHOD

摘要

This assembly comprises a chamber (40) delimiting an internal volume (24) containing an ambient gas and a system (42) for treating the ambient gas. The treatment system (42) comprises an upstream inlet (68) for drawing off ambient gas from the chamber (40), a device (51) for treating the ambient gas and an assembly (50) for conveying the ambient gas from the upstream inlet (68) towards the treatment device (51). The treatment device (51) comprises at least one nitrogen generator (52) capable of generating a nitrogen‑rich treated stream and an oxygen‑rich discharge stream from the ambient gas tapped off. The treatment system (42) comprises a purge assembly (54) connected to the nitrogen generator (52) to discharge the nitrogen‑rich stream to the exterior of the underwater vehicle (10).
