Abstract

The invention discloses a treatment method for oily sludge, which relates to the technical field of garbage treatment. The treatment method comprises: controlling the first pushing device to close the feed bin door; The bin door is opened, and the deoxidized material is transported to the main microwave pyrolysis furnace through the material conveyor belt; the third pusher is controlled to close the main furnace door of the main microwave pyrolysis furnace; temperature-controlled cycle pyrolysis is carried out in the main microwave pyrolysis furnace After the temperature-controlled cycle pyrolysis treatment, the material is conveyed to the auxiliary microwave pyrolysis furnace through the material conveyor belt; the secondary pyrolysis treatment is carried out in the auxiliary microwave pyrolysis furnace, and the residue after the secondary pyrolysis treatment is conveyed to the outlet through the material conveyor belt. feeding device. The invention has the advantages of uniform pyrolysis and high pyrolysis efficiency when the material is heated and pyrolyzed in the microwave cracking furnace.

Description

technical field [0001] The invention relates to the technical field of garbage treatment, in particular to a treatment method for oily sludge. Background technique [0002] Oily sludge mainly comes from petroleum exploration, refining and petrochemical industries. With the increase of oil production, the total amount of oily sludge produced is also increasing, and the pollution to the environment is becoming more and more serious. Therefore, whether it is from the perspective of environmental protection, maintenance of normal production or energy recovery, it is necessary to carry out harmless and resourceful treatment of oily sludge. [0003] At present, the harmless treatment of oily sludge is mainly: the oily sludge is heated by microwave under anaerobic conditions, and then subjected to thermal cracking technology, so as to improve the recovery rate of oil and gas resources in oily sludge, reduce environmental pollution, and improve economic benefits . [0004] For exa...
