Description

Technical Field

[0001] The utility model relates to the technical field of activated carbon regeneration, in particular to an activated carbon regeneration device for inositol decolorization. Background Art

[0002] Activated carbon is a carbon material with a large surface area and high adsorption performance. It is usually prepared from natural substances (such as wood, husks, coal) or artificial materials. The preparation process of activated carbon includes two main steps: carbonization and activation. Activated carbon has a lot of tiny pores, which give it a huge specific surface area, enabling it to efficiently adsorb gases and impurities in liquids or solutions, thereby achieving the purpose of decolorization and impurity removal.

[0003] At present, the activated carbon used in inositol decolorization becomes saturated carbon after a period of use, and the adsorption capacity will be weakened or even completely lost. If it is directly discarded, it will not only waste resources, but also cause secondary environmental pollution. Therefore, the activated carbon needs to be regenerated. Activated carbon regeneration can restore the activity of activated carbon by treating saturated carbon through heating and other methods, but the traditional activated carbon regeneration device occupies a large area and has high operating costs.
