Apparatus for regenerating activated carbon

The utility model relates to an improvement of a high temperature heating type active carbon regenerating furnace. The utility model is characterized in that a regenerating furnace uses an indirectly heated electrical preheating furnace and a regenerating furnace which are separated with each other. The preheating furnace is connected with the regenerating furnace through an air conveying pipe. The preheating furnace and the regenerating furnace are composed of long furnace tubes arranged in a longitudinal way, external electric heating elements and heat-insulating layers. The utility model with good effect and continuous fluidization and regeneration not only can regenerate granular active carbon, but also can regenerate powder active carbon.
