Electric Furnace For Continously Heating And Regenerating Spent Activated Carbon
Electric Furnace For Continously Heating And Regenerating Spent Activated Carbon
US Patent:
4455282, Jun 19, 1984
Filed:
Sep 7, 1982
Appl. No.:
6/415268
Inventors:
Gerald E. Marquess - New York NY
David J. Nell - Oradell NJ
David J. Nell - Oradell NJ
International Classification:
B01J 400, B01J 812, B01J 2034
US Classification:
422199
Abstract:
A furnace for heating particulate material comprises an air-tight shell and a heat insulating lining which define a hollow shaft. Electrical resistance heating elements spaced along the length of the hollow shaft adjacent the insulating lining. A baffle system supported within the shaft promotes heating by radiation and convection. The baffle system has side supports vertically positioned within the shaft, a plurality of inner trays each defining pairs of sloping surfaces joined at a ridge, and a plurality of outer trays each defining a sloping surface. The outer trays are arranged to receive material falling from an inner tray thereabove and to deliver material to the ridge of an inner tray therebelow.

Filed:
Jul 9, 1981
Appl. No.:
6/281691

International Classification:
B01J 400, B01J 812, B01J 2034
US Classification:
422199
Abstract:
A system and method of reactivating wet spent activated carbon comprising a batch operated solid-liquid separator, a continuous feed electrically heated furnace and surge bin therebetween. Heat exchangers recover sensible heat of the exhaust gases and/or hot carbon leaving the furnace to heat the air used by the solid-liquid separator. A portion of the furnace exhaust along with added air is recirculated through the furnace to provide the appropriate atmosphere for regeneration of the carbon.
