Workflow

1. After the drum carbonization furnace is fed, natural gas is used for one-time ignition to achieve the goal of pre-carbonization heating.

2. When the carbonization temperature reaches 270-300 degrees Celsius, the combustible gas generated by the gasification of the carbonized raw materials is recovered, and these combustible gases are used as heat sources to supply the carbonization furnace through the flue gas recovery system. The corrosive liquids of wood tar and wood acetic acid are treated by combustion with the help of fuel, so that the emissions meet environmental protection standards. The circulation system includes a waste heat recovery system, a gas reuse system and an exhaust gas treatment system. The waste heat recovery system includes a plurality of hot water exchange pipes arranged around the cooling zone and a soft water pipe connected to the hot water exchange pipe. In this way, the exhaust gas can be treated, smokeless and environmentally friendly.

3. After the carbonized raw materials release a large amount of flue gas, turn off the natural gas switch to complete the preliminary carbonization work.

4. After about 2-3 hours of carbonization, the carbon powder flows from the carbonization furnace into the cooler for cooling, and the carbonization furnace can be continuously uninterrupted in normal production.

5. The cooled carbon powder is sent out through the feeding pipeline.

The drum carbonization furnace is an automated production line with the advantages of uniform furnace temperature, high thermal efficiency, low energy consumption and simple operation. It solves the problems of high energy consumption and high pollution in the traditional carbonization production process, and converts waste biomass into renewable biomass energy in a pollution-free way, thus realizing the sustainable use of energy.
