A three-dimensional activation network is formed by the gas (water vapor / CO2) (activating gas (water vapor / CO2) is injected into the carrier activated carbon raw material from three directions), which increases the contact rate between the carrier activated carbon raw material and the activation gas (water vapor / CO2), thereby improving the activation efficiency and ensuring the activation effect. The bottom of the activation chamber is equipped with a heating element. During the activation process of the carrier activated carbon, under the control of the PLC controller, heat energy is output to heat the top activation chamber, thereby heating the mixture of carrier activated carbon raw material and activation gas (water vapor / CO2) (75°C).

With the cooperation of the gas valve and the gas meter, an appropriate amount of activation gas (water vapor / CO2) can be injected from both sides of the activation box three through this structure. It forms a three-dimensional activation network with the activation gas (water vapor / CO2) injected into the top of the activation box three through the air inlet pipe three (activation gas (water vapor / CO2) is injected into the carrier activated carbon raw material from three directions). This improves the contact rate of the pre-activation gas (water vapor / CO2) of the carrier activated carbon raw material, thereby improving the activation efficiency and ensuring the activation effect. The activation box three is equipped with a discharge pipe at the end, through which the activated carrier activated carbon is discharged from the equipment. The bottom of exhaust pipe 1, exhaust pipe 2, and exhaust pipe 3 are all equipped with several spiral air outlets. The output ends of the spiral air outlets extend to the inner top of activation chamber 1, activation chamber 2, and activation chamber 3. Through this structure, the activation gas (water vapor / CO2) injected through exhaust pipe 1, exhaust pipe 2, and exhaust pipe 3 can be vertically swirled into activation chamber 1, activation chamber 2, and activation chamber 3 respectively, forming a three-dimensional activation network with the activation gas (water vapor / CO2) injected through the air holes on both sides (injecting activation gas (water vapor / CO2) into the carrier activated carbon raw material from three directions), thereby increasing the contact rate of pre-activated gas (water vapor / CO2) with the carrier activated carbon raw material, thus improving the activation efficiency and ensuring the activation effect. A stirring mechanism is installed inside the primary, secondary, and tertiary activation devices to agitate the activated carbon carrier. During the activation process, the mechanism rotates under the drive of a motor to agitate the activated carbon carrier, allowing the injected activation gas (water vapor / CO2) to come into full and rapid contact with the activated carbon carrier, thereby improving the activation efficiency of the activated carbon carrier. The stirring mechanism includes a stirring shaft, multiple stirring paddles (first, second, and third), and multiple stirring paddles (first, second, and third) are symmetrically welded to the side wall of the stirring shaft. Agitator 1 is located inside the primary activation device, agitator 2 is located inside the secondary activation device, and agitator 3 is located inside the tertiary activation device. One end of the stirring shaft is connected to a reducer, a kinetic energy processing structure. Utilizing the high torque resistance of the gearbox, the output torque of the gearbox is increased by increasing the reduction ratio, thereby reducing the requirement for input torque and reducing the output power of the motor to achieve energy saving. The input end of the reducer is connected to a motor, a kinetic energy output structure, which provides kinetic energy support for the stirring operation of the stirring mechanism. The support frame is located at the bottom of the machine and supports the entire machine.

[0012] In summary, the beneficial effects of this application are as follows: 1. A multi-dimensional combination of activation gas (water vapor / CO2) supply and mechanical stirring is adopted, which expands the contact area between the activation gas (water vapor / CO2) and the carrier activated carbon raw material within an effective time. This not only improves the activation efficiency, but also reduces the differences in activated carbon raw material after activation, reduces the particle breakage rate, and enhances the activation effect.

[0013] 2. A zoned temperature control method is adopted, which sequentially activates the carrier activated carbon raw material through primary, secondary and tertiary activation. This multi-stage gradient activation treatment not only ensures precise temperature control (temperature fluctuations within ±5 degrees Celsius are normal), but also results in high uniformity of micropore development and low energy consumption.

[0014] 3. A D-type gearbox is installed at the motor output end. Utilizing the gearbox's high torque capacity, the output torque is increased by raising the reduction ratio, thus reducing the input torque requirement and lowering the motor's output power, achieving energy savings.

Activation chamber 2 (10) has several vents on both sides. Activating gas (water vapor / CO2) enters the internal channels of activation chamber 2 (10) from both sides. Each vent is connected to a branch pipe (14). The activated gas (water vapor / CO2) injected through the gas supply pipe (13) is dispersed into the pipes of activation chamber 2 (10). The ends of several branch pipes (14) on each side are all connected to the same gas supply pipe (13). The pipes on both sides of the activation box 10 inject activation gas (water vapor / CO2).

This forms a three-dimensional activation network with the activation gas (water vapor / CO2) injected through the air holes on both sides (activation gas (water vapor / CO2) is injected into the carrier activated carbon raw material from three directions), which increases the contact rate of the pre-activated gas (water vapor / CO2) with the carrier activated carbon raw material, thereby improving the activation efficiency and ensuring the activation effect. A stirring mechanism is installed inside the primary, secondary, and tertiary activation devices to agitate the activated carbon carrier. During the activation process, the mechanism rotates under the drive of motor 22 to agitate the activated carbon carrier, allowing the injected activation gas (water vapor / CO2) to come into full and rapid contact with the activated carbon carrier, thereby improving the activation efficiency of the activated carbon carrier.
