|The CVC Carbon Reactivation Furnace restores carbon to its
original adsorptive capacity under conditions similar to its manufacture.
A thin layer of carbon passes slowly between two cylinders heated electrically
to 1500 degrees F. Contaminants are removed by desorption and pyrolysis and
are transported away with the steam from water in the feed carbon. There
is little or no physical degradation of the carbon in the process.
|Spent Granular Activated Carbon is loaded from standard "super
sacks" into a feed hopper and conveyed to the furnace for thermal reactivation.
Contaminants adsorbed on the carbon separate into a vapor stream and the
reactivated carbon leaves the furnace through a heat exchanger. The carbon
is classified by particle size in a closed system. Unreclaimed dust from
the classifier blends with the furnace exhaust in a wet scrubber.
|The regeneration process is highly automated and the operator can observe all key activities from the PLC control panel location. Reactivated granular carbon is collected in super sacks and powdered carbon is collected in drums. The working environment is clean and relatively quiet. A part-time operator with a fork lift can manage all routine functions. The system can be easily housed in a 2500 square foot space.|
