Abstract

The invention discloses an oily sludge treatment method, and relates to the technical field of garbage treatment. The treatment method includes the steps: controlling a first push device to close a feed bin gate; feeding and deoxidizing materials, controlling the first push device to open the feed bin gate, and conveying the deoxidized materials to a main microwave pyrolysis furnace by a materialconveying belt; controlling a third push device to close a main furnace door of the main microwave pyrolysis furnace; performing temperature control cycling pyrolysis treatment in the main microwave pyrolysis furnace, and conveying the materials after temperature control cycling pyrolysis treatment to an auxiliary microwave pyrolysis furnace by the material conveying belt; performing secondary pyrolysis treatment in the auxiliary microwave pyrolysis furnace, and conveying residues after secondary pyrolysis treatment to a discharging device by the material conveying belt. The oily sludge treatment method has the advantages that the materials in the microwave pyrolysis furnaces are uniformly heated and pyrolyzed, and pyrolysis efficiency is high.

Description

technical field [0001] The invention relates to the technical field of garbage disposal, in particular to a method for treating oily sludge. Background technique [0002] Oily sludge mainly comes from oil 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 from the perspective of 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: oily sludge is heated by microwave under anaerobic conditions and treated by thermal cracking technology, thereby improving the recovery rate of oil and gas resources in oily sludge, reducing environmental pollution and improving economic benefits. . [0004...
