Abstract
The invention discloses a treatment system for oily sludge, which relates to the technical field of garbage treatment. The treatment system includes: a feeding device, the outlet of the lower part of the feeding device is located above the material conveyor belt of the horizontal conveying device, including a feeding bin door and a first Pushing device; horizontal conveying device, including material conveyor belt, used to transport the materials output from the feed bin door to the main microwave pyrolysis furnace, auxiliary microwave pyrolysis furnace and discharge device in turn; the main microwave pyrolysis furnace, including temperature control The circulation conveying device, the main furnace door and the third pushing device, and the temperature-controlled circulating conveying device are used to detect the temperature of the material in the main microwave pyrolysis furnace in real time and control the material to be circulated in the main microwave pyrolysis furnace according to the temperature of the material until the material reaches Up to the preset temperature; and the discharge device, etc. 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 system 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...
