AI Technical Summary
In existing traditional pyrolyzers, when materials are cracked at high temperatures, the residence time of hot air in the heating tube is short, resulting in low heat transfer efficiency, insufficient utilization of heat, high energy consumption, and uneven temperature distribution.
The system employs an exhaust protection mechanism and a waste heat utilization mechanism. The hot air is evenly distributed into multiple ventilation ducts through a diversion and conveying mechanism. The airflow direction is adjusted by first and second hot air turbulence fins, which increases the residence time and contact area of the hot air in the heating duct. Combined with the flow guide chamber and waste heat transfer chamber, the heat energy is further utilized to ensure uniform temperature distribution.
Through optimized exhaust protection and waste heat utilization mechanisms, and by designing exhaust protection devices and diversion and conveying mechanisms, efficient heat transfer and uniform distribution are achieved, thereby improving heat utilization and reducing energy consumption.
