FIELD: wood-working industry, in particular, equipment for production of active carbon from charcoal or wood wastes, which may be used as additional facilities in wood-working enterprises.
SUBSTANCE: vertical furnace has vertical chamber (retort) housed within heating furnace having square section and fabricated from refractory steel. Steam is fed through pipe extending through the entire height of retort. Charcoal, shavings, or large-sized chips are charged from charging hopper upon opening of lower shutter of charging hopper and shutter disposed in upper part of retort. Active carbon is discharged into car upon opening of rotary hatch. Pyrolysis and activation process products are burnt in furnace to provide for additional heating thereof. Vertical furnace of such construction allows active carbon to be prevented from combustion to protect environment from ecological contamination.
EFFECT: increased efficiency and improved ecology control.
