DEHUMIDIFIER FOR COMPRESSED AIR

摘要

PURPOSE:To feed sufficiently dried air having low relative humidity by passing compressed air after passing an after-cooler through a path of waste heat to be produced from an engine driven compressor through a conduit and performing heatexchange. CONSTITUTION:Compressed air is separated of lubricant through a separator in a receiver tank 3 and led to an after-cooler 4 then cooled to exhibit saturated state. Thereafter condensed water is separated through a drain trap 5 and fed to the secondary flow path of an after-warmer 6. Hot cooling water after cooling an engine 2 is fed to the primary flow path of after-warmer 6, thereby compressed air cooled by the after-cooler 4 will be heat-exchanged with said hot cooling water in the after-warmer 6 then dried and fed through the outlet of secondary flow path as dry air having low relative humidity.
