Activated carbon regenerating kiln

Brief introduction of activated carbon regnerating kiln

 The activated carbon regenerating kiln  is usually used to regenerat the barren carbon from the elution and electrowinning system.

Structure

Working principle

The active carbon adsorbs the thermal decomposition type and hard to desorption type organic material, through the heating of activated carbon at high temperature, volatiles and carbonizes the organic material, then to complete the whole regeneration, the carbide and active carbon activated simultaneously. The regeneration process can be divided into three stages:

1) Drying

Heat the hydrous activated carbon to evaporate the adsorbed water and volatilize some low boiling point organic compounds.

2) Carbonation

Heat up the activated carbon continually, the different organic matter will volatilize, decompose, or carbonize.

3) Activation

After the high temperature carbonization of organic matter, there are some carbides residual left in the micropore of activated carbon, at the same time carbides active through the steam etc oxide gas to gasify the residuals, through which to clean the activated carbon’s micropore, and also generate some new micro hole, both work together to activate activated carbon.

The reaction equation of carbides and oxide gas as follows:

        C+O₂=CO₂

       C+H₂O=CO+H₂

       C+CO₂=2CO

Technical specification

Actieated carbon regenerating kiln usually used in CIL and CIP plant, such as the following flow sheet
