Electric furnace for continously heating and regenerating spent activated carbon |
摘要 |
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.
