摘要： A carbon reactivation apparatus has a fossil fuel kiln adjacent to a rotary dryer and flue gas from the kiln flows through the dryer co-currently with carbon particles to provide a more efficient process than previously known. The apparatus has a rotary kiln with a drum therein sloped downwards from a feed end to a discharge end, a furnace shell surrounding at least a portion of the drum with a fossil fuel heater and hot gases from within the shell heat the rotary kiln. A rotary dryer slopes downwards from an inlet end to an outlet end and carbon particles to be reactivated are fed into the inlet end. Ducting from the shell surrounding the drum of the rotary kiln extends to the inlet end of the rotary dryer for hot gases to flow along the dryer to the outlet end in the same direction as the carbon particles. Carbon particles are discharged from the outlet end of the rotary dryer into the feed end of the rotary kiln, the carbon particles being separated from the hot gases in the rotary dryer, and there is an exhaust system to exhaust the hot gases from the outlet end of the dryer.

A recycling dryer has input ducts connected to the existing aggregate dryer discharge ducts and output ducts connected from the recycling dryer back to the existing ducts to the filtering system. A recycle feeder bin for feeding reclaimed asphalt pavement to the recycle dryer is connected to the recycle dryer. A recycle booster burner is operatively connected to the recycle dryer through the input duct to the dryer for providing additional heat to the recycle dryer so that the waste heat from the existing aggregate dryer and the booster burner provide a predetermined heat to the recycle dryer for heating the asphalt material. A recycling storage bin or silo is connected to receive the heated recycled asphalt from the recycle dryer. A hammermill or other means may be provided for breaking up the old asphaltic materials, such as old paving materials prior to entry of the material into the recycle dryer. Dampers are provided for directing heated gases from the existing batch type asphalt plant to the recycling system, as needed, and temperature controls are utilized to control the recycled booster burner to provide the right combination of existing waste and added heat for the recycled dryer. The stored recycled asphalt materials may be fed to an existing plant batching tower for batching and loading into vehicles.
