AI Technical Summary

Problems solved by technology

[0002] Conventional energy pyrolysis equipment mainly uses conventional energy sources (such as electricity, coal, gas, etc.) to heat up the furnace body by externally heating the furnace body. Conventional energy sources have low heat conversion efficiency (generally, the heat utilization efficiency is only 30~ 40%), slow aging, high energy consumption, and the emissions after conventional energy combustion will cause secondary pollution

[0003] Conventional energy pyrolysis equipment has a small processing capacity when dealing with oily solid waste produced in oil field exploitation, and the open flames generated by external heating have great safety hazards and the equipment furnace is easily coked.

[0004] The existing microwave rotary furnace equipment has a low material filling rate, generally only 6% to 15%, resulting in low production capacity

The existing microwave rotary kiln equipment has a microwave source that can only feed microwave energy from one direction of the kiln head, and the number and area of ​​feed ports are greatly limited, resulting in uneven microwave field and low heating efficiency

Existing rotary kiln equipment is generally atmospheric equipment and the airtightness between the kiln head and the kiln body is poor. The inside of the furnace body cannot isolate oxygen from contact with the material, and cannot handle materials with dangerous gas volatilization, which may catch fire or even explode.
