Self Circulation SlEP Activated Carbon Kiln Vertical Activation Furnace

SELP activation furnace,Vertical activation furnace,Coal based columnar activated carbon furnace

Material process:
After the material enters the feeding tank, it slowly descends along the product path under the action of gravity, passing through the pre heating zone, supplementing the carbonization zone, activation zone, and cooling zone to complete the entire activation process. Finally, it is discharged by the lower unloader. The carbonization preheating section uses the heat in the furnace to preheat and remove moisture. In the supplementary carbonization section, the carbonized material is indirectly heated by high-temperature activation gas to continuously increase the temperature of the carbon for supplementary carbonization. In the activation section, the activation channel is connected vertically to the activation gas channel, Carbon is activated by direct contact with the activated gas. In the cooling section, the activated material is cooled with circulating water (or air cooled), so that the temperature of the obtained activated material can be reduced to below 60 ℃, facilitating material transportation and direct screening and packaging

Gas process:
The gate valve of the left half furnace flue is closed, and the gate valve of the right half furnace flue is opened. Water vapor enters from the bottom of the left half furnace regenerative chamber, is heated by grid bricks to become high-temperature steam, and enters from the upper flue. After the steam reacts with the material, the water gas and residual steam generated sequentially pass through the upper part of the left half furnace, and the middle and lower flue enter the right half furnace. The mixed gas in the right half furnace enters the top of the right half furnace regenerative chamber through the lower, middle, upper flue, and upper flue, Then flow down through the grid bricks, while heating the grid bricks, cooling the exhaust gas, and entering the flue to complete the cycle. The second cycle is the opposite of the above cycle. The first and second cycles switch every half an hour, so that the activation process continues continuously

SELP activation furnaces are generally suitable for production lines of coconut shell carbonized materials, coal based carbon, and cylindrical activated carbon.
