Abstract

PURPOSE: To eliminate occurrence of fine dorplets by providing a cooler for cooling the exhaust air from a cave passage in the vicinity of the air outlet of the passage.
CONSTITUTION: A spiral fin 3 is provided in the vicinity of the air outlet 2 in a cave passage 1 laid with cables or the like. A cooling water circulating device 4 is provided to cool the fin 3. Since the exhaust air from the passage 1 is cooled by the cooler before making contact with the atmospheric air, its humidity is lowered to reduce the temperature difference between the exhaust air and the atmospheric air and to accordingly eliminate the occurrence of fine droplets in mist state.
