APPARATUS FOR REHEATING COMPRESSED AIR

摘要

PROBLEM TO BE SOLVED: To provide an apparatus for reheating compressed air, which can reheat the compressed air by efficiently utilizing high-temperature water separated in a previous stage of a compressed air dehumidifier system.SOLUTION: An apparatus for reheating compressed air includes: an air compressor 3 which serves as a compressed air generation source; air piping which includes an air circulation pipe 12, an introduction pipe 13 and an exhaust pipe 14; drain piping which includes drainage connection pipes 10 and 15 and drain pipes 11 and 16; a separator 5; an air tank 7; and drain ejectors 6 and 8. The drain pipe 11 is provided with a reheater 4 which exchanges heat between the low-temperature compressed air discharged from a compressed air dehumidifier system 2 and high-temperature water separated by the separator 5 and the air tank 7 and discharged.
