Title: Regenerated pre-drier lengthening the life of static driers - for air used in ozone prodn.
Inventor: BACHHOFER BRUNO
IPC: F24F3/14
Filed: 1979-09-13
Abstract: The replaceable static drier used for the process air for ozone prodn. and filled with moisture- adsorbent material is preceded by a pre-drier automatically regenerated by heating the drying material. While the pre-drier is in operation, the pipe which connects the driers is blocked, though a suction line continues to take atmospheric air into the static drier. A pneumatic switch at the pre-drier outlet actuates a timer for the heating which only functions while the connecting pipe is at sub-normal pressure. The electrical resistance heating system includes a thermo-switch and a solenoid which actuates the blocking valve, with the connecting pipe remaining blocked until the drying medium falls to a specific temp. The very reliable static driers which with intensive use or extra moist atmos. would need premature replacement have their lives extended by the accompanying pre-drier, and are only changed at the routine times.
