Abstract

A desiccant media containing cartridge for use in a gas drying apparatus adapted to firstly function in a gas drying cycle in which a moist gas is permitted to pass upwardly through said desiccant media whereby at least a portion of the moisture is removed from said gas, and adapted to secondly function in a desiccant media purge cycle in which a portion of said dried gas is allowed to pass back downwardly through said desiccant media to absorb moisture therefrom thereby at least partially regenerating said desiccant media, including a means for concentrating the desiccant purge cycle at the bottom of the desiccant media, which means comprise a purge tube extending vertically partially through the desiccant media, and a flapper valve adjacent to an upper end of the purge tube adapted to close and restrict flow of gas through the purge tube when the gas is flowing upwardly in during the gas drying cycle and to open and promote gas flow through the purge tube when the gas is flowing downwardly during the desiccant purge cycle.
