Abstract

See full text

A method and device for regeneration of an adsorption air dryer having at least two desiccant-filled drying vessels connected in parallel, wherein a humid compressed-air stream generated by a compressor flows through one of the drying vessels in a drying phase and a dry compressed-air stream flows through the other drying vessel, for the purpose of dewatering the desiccant, in a simultaneous regeneration phase, wherein a valve arrangement is provided for switching the drying vessels alternately between drying phase and regeneration phase during normal operation, wherein the control mechanism are provided for implementing a post-regeneration phase, which control mechanism initiates a further flow through the drying vessel with dry compressed air for complete regeneration and also a flow through the other drying vessel; with dry compressed air for complete regeneration, so that, upon the next start of operation of the adsorption air dryer, operation commences with fully regenerated drying vessels.
