The invention relates to a thermal regeneration furnace for waste powdered
activated carbon, and belongs to the technical field of
chemical industry. The thermal regeneration furnace is used for the thermal regeneration (100 to 850 DEG C) of waste powdered
activated carbon obtained by refining and decolorizing medicines and fine chemicals. The thermal regeneration furnace is formed by serially connecting a plurality of
dry distillation trays and activation trays, which are provided with rotary stirrers, wherein the
dry distillation trays are vertically arranged on the activation trays; and waste powdered carbon is continuously and quantificationally added, indirect heating is adopted for
dry distillation, the activation is that high-temperature activation gas is generated by using
water gas generated in the thermal regeneration process and an
oxygen-enriched
combustion improver, and over-heated
water vapor is doped and taken as activation gas for direct
contact activation,
organic matter in the waste carbon can be completely decomposed and removed through dry
distillation and activation in an innocent manner, the waste powdered carbon can be generated, and the original adsorption performance and the original adsorption indexes are restored. The thermal regeneration of the waste powdered carbon is a most effective technical means for realizing the cyclic utilization of
industrial waste powdered carbon, environmental
pollution caused by inappropriately disposing the waste powdered carbon which is taken as garbage, and also ensures that powdered carbon resources are recycled; and the thermal regeneration also has a relatively high economic benefit.
