Problems solved by technology

Both of the above two activation furnaces take certain measures to improve the mass transfer and heat transfer between the material and the gas-phase activation medium (such as steam, flue gas), but due to the influence of gravity, the material accumulates on the wall of the reactor (chamber) and cannot The gas-phase activation medium efficiently transfers mass and heat, and cannot efficiently take the evaporated organic vapor away from the reactor (chamber), which affects the activation efficiency
In addition, if there is no reliable sealing, the organic vapor under such high temperature conditions will overflow and cause safety accidents, and at the same time, toxic and harmful pollutants (such as CO) may be formed, and the overflow of dust will also pollute the environment.

Embodiment 1

[0019] Such as figure 1 , figure 2 , image 3 As shown, a special equipment for preparing activated carbon, the special equipment is an activation tower, and the activation tower includes a tower body 4, a feed pipe 9 arranged at the upper end of the tower body 4, a high-temperature flue gas inlet pipe arranged at the upper end of the tower body 4 Air pipe 8, the centrifugal spray head assembly that is located at the upper end of tower body 4, the superheated steam inlet pipe 5 that is located at the centrifugal spray head assembly below, described tower body 4 is a closed space, and described tower body 4 comprises cylinder body 6, design A mixing chamber 7 at the upper end of the cylinder 6, a collecting hopper 2 at the lower end of the cylinder 6, and a material outlet 1 at the lower end of the collecting hopper 2. The centrifugal nozzle assembly includes a volute nozzle 10 and a transmission rod 11. The volute nozzle 10 is fixed on the lower end of the transmission rod ...

Embodiment 2

[0021] Such as figure 1 , figure 2 , image 3 As shown, a preparation method for preparing activated carbon: the charcoal material that has completed the carbonization treatment enters from the feed pipe 9 on the tower top 4, is evenly dispersed through the centrifugal nozzle assembly, and is thrown to the inner wall of the mixing chamber 7, and along the mixing chamber 7. The activated medium high-temperature flue gas and superheated steam that enter the tangential direction of the inner wall of the tower body 4 are fully mixed, and under the action of centrifugal force, move downwards along the wall surface of the tower body to the collecting hopper 2, and finally discharge through the material outlet 1 at the bottom of the collecting hopper , to complete the activation process. The activation process uses a tower reactor to perform the activation reaction. The activation medium is high-temperature flue gas and superheated steam, and other activators can also be used.
