Treating method of extinguishment exhaust gas in room provided with electric power system

Abstract

Abstract PURPOSE: To make the titled extinguishment gas contg. halide pollution-free rapidly and quickly restore electrical power systems by passing said gas in the dry type capturing agent packed layer that makes halide nonvolatile then passing the same through the wet type treating vessel using water. CONSTITUTION: The extinguishment exhaust gas contg. gaseous halide and heavy smoke produced with the extinguishment of fire in a titled room 1 is sucked by a fan 7 and is passed through a dry type treating vessel 12 packed with the granular capturing agents 8 comprising essentially carb onates and hydroxides of Ca, Al, etc. forming nonvolatile halide by reacting with halide. After this, it is passed through a wet type treating vessel 9 in which water is sprayed by a pump 10, circulating pipe 11 with nozzles, etc., whereby the harmful hydrogen halogenide, etc. are made pollution-free and are exhausted from a duct 5. Thence, no halogen ions are contained in the exhaust water and no secondary treatment of water is required, thus the exhaust gas treating apparatus is made smaller in size and electric power systems are restored rapidly.
