Description
A METHOD OF REGENERATING ACTIVATED CARBON
TECHNICAL FIELD
The invention relates to a method of regenerating activated carbon.
BACKGROUND
The traditional method of regenerating activated carbon is performed by manually disposing the waste activated carbon in a clay tank, moving it to the earth kiln for heating and regeneration, and heating it from a temperature of 30 °C to 900 °C with wood. After heated at a constant temperature for 18 hours, it is directly sprayed with water to cool down to 30 °C, manually moved out, and screened using a screening machine. The traditional method of regenerating activated carbon may cause serious pollution, high labor cost, high energy consumption, low and unstable quality of activated carbon.
Any discussion of the prior art throughout the specification should in no way be considered as an admission that such prior art is widely known or forms part of common general knowledge in the field.
It is an object of the present invention to overcome or ameliorate at least one of the disadvantages of the prior art, or to provide a useful alternative.
SUMMARY
The invention is to solve the technical problem that the method of regenerating activated carbon of prior art may cause high energy consumption, high labor cost, low and unstable quality for activated carbon, so as to provide a method of regenerating activated carbon that causes low energy consumption, and achieve environmental protection and may produce high quality activated carbon.
