Description

Technical Field

[0001] The present invention relates to the technical field of pyrolysis carbonization, and in particular to a pyrolysis carbonization system and a continuous production method for biomass and solid waste. Background Art

[0002] Pyrolysis carbonization refers to the process of converting organic matter into liquid and gaseous carbonaceous residues through heating in an oxygen-free or low-oxygen environment. Widely used in energy production, carbon material preparation, and waste management, it not only maximizes waste resource utilization but also reduces environmental pollution and greenhouse gas emissions. With the growing global demand for renewable energy and environmentally friendly technologies, pyrolysis carbonization technology has garnered widespread attention as an effective method for converting organic waste into high-value-added products, offering a more efficient solution for the current treatment of biomass and solid waste.

[0003] Currently, the pyrolysis carbonization process is carried out under heating conditions of 200°C to 900°C, which also requires an oxygen-free or low-oxygen process environment. The conventional pyrolysis carbonization production method is to use a small carbonization furnace and produce in batches. Although the process parameters of a small carbonization furnace are easy to meet, conventional small carbonization furnaces still have the following shortcomings:

[0004] 1. Low production efficiency: Traditional equipment is mostly intermittent operation, which makes it difficult to achieve continuous production, resulting in low production efficiency;
