Continuous Waste-Plastic Pyrolysis With Heated Airlock Feeding

The patent implements a continuous pyrolysis system where plastic waste is continuously fed into the reactor, processed, and discharged as fuel products without batch interruptions. The system maintains continuous operation through a designed flow path that eliminates the need for repeated sealing and opening operations, thereby achieving both continuous productivity and sealing reliability.

The system performs preliminary heating and preparation actions before the main pyrolysis process begins. The reactor is pre-heated to the required temperature, and feedstock is pre-processed, which reduces the actual start-up time and energy consumption during operation. This preliminary action ensures that when material is introduced, the pyrolysis reaction begins immediately without prolonged warm-up periods.

The patent introduces an intermediary cooling medium or heat exchange mechanism that allows efficient heat transfer without requiring direct contact between the reaction zone and external cooling systems. This intermediary system maintains the sealed environment for safety while enabling effective heat exchange through controlled thermal pathways, thus preventing oxygen leakage without compromising heat exchange efficiency.

The system is designed to utilize the inherent properties of the plastic waste feedstock and the pyrolysis reaction conditions to produce fuel without requiring complex external catalyst systems. The process leverages self-catalytic mechanisms or simple thermal cracking that occurs naturally at the operating temperatures, thereby achieving productive fuel generation while maintaining relatively simple device architecture and avoiding the complexity of catalyst handling, regeneration, and separation systems.
