Assignee:
Primary Examiner: Lopez; F. Daniel
Assistant Examiner:
Attorney, Agent or Firm: Potthast & Ring

An improved regenerative gas drying system (30) having an adsorbing chamber (36) and a regenerating chamber (46) with both chambers containing desiccant (38) in which the adsorbing chamber (36) receives wet gas (31) for adsorption of moisture by the desiccant (38) contained therein to create a drier gas (40) and in which a portion of the drier gas (40) exits the adsorbing chamber (36) and is directed and carried to the regenerating chamber (46) to dry the desiccant (38) contained within the regenerating chamber (46). A chamber drier gas heating apparatus has a conduit (55) disposed within the desiccant (38) of the regenerating chamber (46) in which the conduit (55) carries the drier gas (40) directed from the adsorbing chamber (36) to the regenerating chamber (46) and includes a microwave antenna (48) in communication with microwaves (50) generated by a microwave generator (54) coupled with the antenna (48) in which at least a portion of the antenna (48) is positioned within desiccant (38) contained in the regenerating chamber (46). A method is further provided for positioning a conduit (55) within the desiccant (38) of the regenerating chamber (46) in which the conduit (55) carries the drier gas (40) directed from the adsorbing chamber (36) to the regenerating chamber (46) and positioning a microwave antenna (48) in communication with microwaves (50) generated by a microwave generator (54) coupled with the antenna (48) in which at least a portion of the antenna (48) is positioned within desiccant (38) contained in the regenerating chamber (46).

DETAILED DESCRIPTION Accordingly, it is the principal object of the present invention to provide a regenerative gas drying system which overcomes the problems of known gas drying systems by efficiently utilizing microwave energy and purge gas during a regeneration cycle to desorb moisture absorbed by desiccant in a chamber.
Another object of the present invention is to provide a conduit disposed within the desiccant of the regenerating chamber in which the conduit carries the drier gas directed from the adsorbing chamber to the regenerating chamber and provide a microwave antenna in communication with microwaves generated by a microwave generator coupled with the antenna in which at least a portion of the antenna is positioned within desiccant contained in the regenerating chamber which will cause desorbing of moisture carried by the desiccant in the regenerating chamber and heating of the dry gas carried by the conduit.
Another object of the present invention includes providing a method for positioning a conduit within the desiccant of the regenerating chamber in which the conduit carries the drier gas directed from the adsorbing chamber to the regenerating chamber and positioning a microwave antenna in communication with microwaves generated by a microwave generator coupled with the antenna in which at least a portion of the antenna is positioned within desiccant contained in the regenerating chamber which causes the desorbing of moisture carried by the desiccant in the regenerating chamber and heating of the drier gas carried by the conduit.
