Continuous carbonization furnace

Carbonization is a chemical process that converts organic substances into carbon. In a continuous carbonization furnace, the carbonization principle involves two main steps: pyrolysis and carbonization.

  First is the pyrolysis process. Under high temperature conditions, the organic substances in the feedstock undergo pyrolysis reactions, decomposing into gases, liquids, and solids. This is a thermodynamic process where large organic molecules break down into smaller organic compounds, releasing gases and volatile substances.

 Next is the carbonization process. Building upon the pyrolysis reaction, the remaining solid portion further transforms into pure carbon compounds. This is a chemical reaction process. Under high temperature conditions, the carbon elements in the carbonization material recombine and form carbon with a porous structure.

 A continuous carbonization furnace is an equipment used for carbon production, employing a continuous processing technique. It utilizes controlled temperature and time to subject the feedstock (such as wood, husks, coconut shells, rice husks, etc.) to carbonization reactions, resulting in carbon products.

 A continuous carbonization furnace typically consists of a feeding system, carbonization zone, cooling zone, and discharge system. Firstly, the feedstock is conveyed into the furnace through a conveyor belt or screw conveyor, ensuring a smooth introduction into the carbonization zone. Inside the carbonization zone, by controlling the temperature and atmosphere, the feedstock undergoes high-temperature treatment, experiencing pyrolysis and carbonization reactions. These reactions vaporize the organic matter of the feedstock and generate carbonaceous substances.

 The carbonized material then moves through the furnace on a conveyor belt into the cooling zone. Within the cooling zone, the carbonized product rapidly cools to prevent excessive oxidation. The cooled activated carbon product is smoothly discharged from the furnace through the discharge system.

Compared to traditional intermittent carbonization furnaces, continuous carbonization furnaces boast several advantages, with the most notable being the ability to conduct the carbonization process continuously, thereby enhancing production efficiency and output. The working principle involves providing a high-temperature environment within consecutively arranged furnace chambers, where the raw materials are continuously fed into the chambers through a conveyor system, while the carbonized products are continuously discharged from the chambers. This continuous feeding and production approach streamline the manufacturing process, reducing downtime.

Continuous carbonization furnaces have also garnered significant attention due to their environmental-friendly emission reduction and energy-efficient characteristics. Typically designed in a closed manner, they effectively prevent harmful gas leakage and are equipped with emission gas treatment systems, effectively reducing the release of harmful gases such as carbon dioxide and nitrogen oxides, complying with environmental protection requirements. Furthermore, these furnaces incorporate internal heat exchange and heat recovery systems to fully utilize generated waste heat, lowering energy consumption and optimizing energy utilization.

In summary, the continuous carbonization furnace is a highly efficient and eco-friendly device that enables continuous carbonization, transforming organic materials into top-quality solid charcoal. Its continuous production approach, emission reduction capabilities, and energy efficiency make it a significant technology in the field of carbonization.
