Activated Carbon Regeneration
AGICO offers activated carbon thermal regeneration plants with an annual capacity of 3000-10000 tons. The customization service is available so that we can meet any production needs.
What is activated carbon regeneration? Activated carbon regeneration means the adsorbed saturated activated carbon regains activity and adsorption capacity after activation treatment to achieve repeated use. It saves the cost of secondary purchase of activated carbon, reduces the waste of energy, and is conducive to the development of the circular economy.
AGICO adopts the activated carbon rotary kiln and a series of professional equipment to desorb the impurities in the waste activated carbon by using high-temperature steam so that the waste activated carbon recovers the adsorption capacity. This production method has the characteristics of a simple process, less pollution, and large output. AGICO has rich experience in production and export. We provide EPC projects for activated carbon plants worldwide.
AGICO is professional in helping customers to build activated carbon regeneration plants with low cost and large output. If you are interested, please feel free to contact us!
Activated Carbon Regeneration Process
Preheating Stage (300-600℃):
Before running, the burner preheats the rotary kiln body and the combustion chamber. The waste activated carbon is fed into the feed bin by the elevator and then fed into the rotary kiln by the frequency conversion feeder. In the kiln, the waste activated carbon is dried under the combined action of the lifting plate and the waste heat of the exhaust gas.
Desorption Stage (900-1050℃):
The dried waste activated carbon moves forward continuously in the rotary kiln and slowly enters the desorption stage. The temperature and steam at this stage determine the quality of regeneration. The time is about 25-35 minutes, and the steam volume is 2-3 tons/hour. Usually, we need to gradually turn on the steam after the temperature is stable and reduce the heat supply, making the water vapor react with the carbon to produce water gas so that the micropore surface in the carbon is cleaned. The steam needs to penetrate the activated carbon and an appropriate amount of oxygen can be used to achieve the best regeneration effect.
After the waste activated carbon is regenerated, it is rotated and discharged through the cooling tube of the rotary kiln, and then enters the water cooler, where it is water-cooled for about 3 minutes in an oxygen-free state. After that, it enters the finished product silo through a closed air conveying device.
Waste Gas Treatment Stage:
The draught fan sends the waste gas into the combustion chamber for high-temperature combustion, and then sends it to the waste heat boiler. After that, the boiler draught fan feeds the waste gas into the quench tower, condenser, quicklime jet tower, activated carbon jet tower, cyclone dust collector, and bag filter in turn finally discharging it at an altitude of 35 meters.

The production cycle of the AGICO activated carbon regeneration plant is about 2 hours, and the whole process is controlled by negative pressure sensing.
The entire production process does not produce any waste water or solid waste. All exhaust gas is converted into carbon dioxide and discharged into the atmosphere after treatment.
AGICO activated carbon regeneration plant adopts the countercurrent external heat method, which greatly improves the output. Compared with the old production method, its output is increased by 60%-80%.
AGICO activated carbon regeneration plant can realize fully automatic and continuous production. It is controlled and monitored by a PLC control system, requiring little labor. In the production process, adjustments can be made in time to prevent accidents.
Different waste activated carbon adsorbs different organic or inorganic components so the amount and composition of waste gas produced are also different. AGICO activated carbon regeneration plant has been designed with full consideration of the complexity of raw materials. All of our equipment is resistant to high temperature and corrosion.
