Carbonization and activation equipment and carbonization and activation process

Abstract

The application discloses a carbonization and activation equipment, which includes a swing-type rotary furnace. The feed end of the drum of the swing-type rotary furnace is higher than the discharge end, and the drum is sequentially composed of a drying section, a dry distillation section, a carbonization section, an activation section, and a gas-solid Separation section; the gas phase area of ​​the carbonization section is provided with a gas introduction assembly for introducing oxygen-containing gas; the solid phase area of ​​the activation section is provided with a steam introduction assembly for introducing water vapor; the gas phase area of ​​the gas-solid separation section is provided with a pyrolysis gas Export. Due to the adoption of a swing-type rotary furnace, heating devices, gas introduction components and steam introduction components can be installed on the drum to ensure the heat treatment of each process section of the drum, and carbonization and carbonization can be completed in one swing-type rotary furnace. Activation and other processes. The application also discloses a carbonization and activation process.

Description

technical field [0001] The invention relates to the technical field of chemical equipment, in particular to a carbonization and activation equipment. It also relates to a carbonization and activation process. Background technique [0002] Activated carbon and activated coke are powdery or granular substances with adsorption and catalytic effects, which are widely used in daily life and chemical production. At present, a kind of equipment for producing activated carbon and activated coke is a rotary kiln, and the material for producing activated carbon is mainly carbonized material. [0003] Existing rotary furnaces are usually composed of a drum, a furnace head and a furnace tail, wherein the furnace head and the furnace tail are fixedly rotated and sealed around the two ends of the drum, and are dynamically and statically sealed with the two ends of the drum, and the drum is driven by an external drive device. Rotate continuously. Due to the continuous rotation of the dr...

AI Technical Summary

Problems solved by technology

Due to the continuous rotation of the drum, the material can only enter and exit at the furnace head and the furnace tail, and other pipes, heating components and sensors cannot be installed on the outer peripheral wall of the drum, resulting in the inability to perform process control on the materials at various positions in the axial direction of the drum. Therefore, Most of the existing rotary furnaces can only complete one of the carbonization or activation processes, and cannot complete the production of activated carbon and activated coke in the rotary furnace at one time, and the equipment and process are complicated.

In addition, since the furnace head and the furnace tail are sealed and connected around the two ends of the drum, the sealing surface between the two ends of the drum and the furnace head and the furnace tail is relatively large. Due to the thermal expansion and contraction of the furnace body and the limitation of high-temperature dynamic sealing materials for rotary furnaces working at high temperatures, the sealing effect is very poor, which has a great impact on the production process

[0004] In summary, how to solve the problem that the existing rotary furnace cannot complete the carbonization and activation process at one time has become an urgent problem to be solved by those skilled in the art
