Embodiment 2
[0059] This embodiment provides a treatment method for oily sludge, which can be applied to the treatment system for oily sludge in Embodiment 1. The treatment method includes the following steps:
[0060] S1, control the first pushing device 15 to close the feeding bin door 14;
[0061] S2. After the material is fed and deoxidized, the first pushing device 15 is controlled to open the feeding bin door 14, and the deoxidized material is transported to the main microwave pyrolysis furnace 3 through the material conveyor belt;
[0062] S3, control the third pushing device 35 to close the main furnace door 34 of the main microwave pyrolysis furnace 3;
[0063] S4, temperature-controlled cyclic pyrolysis treatment is performed in the main microwave pyrolysis furnace 3, and the material after the temperature-controlled cyclic pyrolysis treatment is transported to the auxiliary microwave pyrolysis furnace 4 through the material conveyor belt;
[0064] S5 , performing secondary pyro...
