Technical Field

[0001] The invention relates to the technical field of microwave heating, in particular to a gravity vertical flow microwave pyrolysis device for continuous pyrolysis. Background Art

[0002] Microwave heating refers to the process of converting microwave electromagnetic energy into the internal energy of the heated object under microwave radiation, which manifests as a macroscopic temperature rise. The main influencing factors of microwave heating are microwave power, microwave frequency, reactor cavity, dielectric properties of the heated object, etc. Microwave heating has been widely used in kitchen appliances, industrial production, medicine, biomass pyrolysis and other fields.

[0003] However, the current microwave pyrolysis reactor still has some problems in experimental application and actual production use. In particular, in the actual production process, the microwave reactor cannot achieve continuous feeding, which leads to long-term cooling of the pyrolysis chamber and frequent feeding and discharging operations, reducing the pyrolysis production efficiency. In view of the above problems, the present invention provides a gravity vertical flow microwave pyrolysis device for continuous pyrolysis. Summary of the invention
