FIELD: equipment for preparation of nitrogen-hydrogen protective atmosphere. SUBSTANCE: proposed plant includes combustion chamber, condensate evaporator, carbon oxide conversion apparatus, tubular cooler, entrainment separator, adsorber and vacuum pump. Mounted in adsorbers at inlet and outlet of plant are taper-shaped baskets filled with metal rings and space between them is filled with adsorbent. At inlet of bottom mixture fed to adsorber for cleaning, basket is mounted with cone towards flow and towards purge gas flow at adsorber outlet; purge gas is fed in counter flow at regeneration of adsorbent. EFFECT: enhanced efficiency. 2 cl, 1 dwg |
