Process description of lignite pyrolysis equipment (carbonization machine):

Lignite rotary pyrolysis/carbonization furnace is an externally heated carbonization rotary furnace used for carbonizing lignite raw materials at high temperatures in the production process of lignite activated carbon. The external heating carbonization converter adopts various sealing combinations such as labyrinth seals and mechanical seals at the furnace head and tail; The heating system adopts segmented internal insulation jackets based on the required heating temperature and air volume, which has a high heat utilization rate; The inner liner of the cylinder body is made of different heat-resistant steel plates or stainless steel plates according to the heating temperature and bending stress. The cylinder body is equipped with a combination of plates that rotate in the opposite direction of the cylinder body to increase the heat exchange area, evenly heat up the material, and ensure that the material is not lifted, reducing the crushing rate. The use of this external heating carbonization rotary furnace has enabled large-scale production of the carbonization process of the new lignite activated carbon and activated coke production process, providing intermediate raw material guarantee for the subsequent production of lignite activated carbon.

Structural composition of lignite carbonization furnace:

The external heating carbonization rotary furnace consists of transmission device, feeding device, large gear ring, cylinder, rolling ring, jacket seal, jacket, discharge seal, discharge box, bracket, supporting wheel device, blocking supporting wheel device, and other components.
