US 2001/0055360 A1 · Apparatus for treating air containing hydrogen gas

Abstract

An apparatus for treating air containing hydrogen gas used in an area such as an interior of a nuclear reactor containment vessel where hydrogen gas is generated and apt to be accumulated so as to treat rapidly and safely the hydrogen. A treating apparatus (30) for treating air containing hydrogen gas in a nuclear reactor containment vessel, comprises a housing (31) provided with an air intake port (33) and an exhaust port (35) and defining a gas passage therein, a catalyst bed (37) disposed in said gas passage, and a heater (39) disposed in or close to said catalyst bed. The catalyst bed is composed of plate type catalysts, honeycomb type catalysts, or spherical catalysts and activated by being heated with an electric heater. Hydrogen and oxygen in the air containing hydrogen gas flowing in come into contact with the catalyst bed and recombine together such that the hydrogen gas is thus removed from the air.
