THERMAL MODULE FOR PREPARATION OF CARBON SORBENTS Russian patent published in 1997 - IPC

FIELD: equipment for thermochemical processes of treatment of grain materials; carbonization and activation in production of active carbons. SUBSTANCE: module includes rotary carbonization and activation furnaces technologically connected by material and gas flows into single complex which is additionally provided with activation gas afterburning furnace mounted near activation furnace. This additional furnace is connected with unloading chamber. Firebox of carbonization furnace mounted separately is provided with heating chamber where heat-transfer agent superheating recuperator is mounted (air is used as heat-transfer agent). Recuperator is connected with heat-transfer supply and discharge chambers. Besides that, firebox is connected with unloading chamber of carbonization furnace. EFFECT: enhanced reliability. 2 dwg
