The invention discloses a spent
activated carbon regeneration method, which comprises the steps of storage, pretreatment,
heating power preparation,
roasting, aftertreatment and packaging as well as preheating and the like. The optimal
activated carbon regeneration
processing steps are screened out through a large number of experiments. According to the regenerative
activated carbon produced by the regeneration method, the adsorptive property of the regenerative activated carbon reaches 95 percent to 110 percent of original activated carbon, the intensity basically does not change, the regeneration rate can be kept above 90 percent and in a whole regeneration and activation process,
biomass particle combustion furnace equipment is used, by combusting
biomass fuel, sufficient
heating power is provided for a high-temperature activation region in the middle of a
tunnel kiln, so that the product quality of the regenerative activated carbon is facilitated, the
raw material loss can be greatly reduced, and the economical and biological benefits are good. Meanwhile, the technology is scientific and reasonable, mature, safe and environment-friendly, and secondary
pollution cannot be caused to the environment, the waste is turned into treasure, so resource waste and environment
pollution can be reduced, and important economic value and
social benefits are achieved.
