Abstract

The invention discloses a harmless, recycling and integrated oil sludge treatment method and belongs to the technical field of oil sludge treatment. The method is characterized by including: feeding oil sludge into a temperature thermal cracking device for preliminary cracking; feeding oil sludge residue after preliminary cracking into a secondary thermal cracking device for in-depth cracking; fully utilizing the secondary thermal cracking device to consume secondary pollutants generated in an upstream treatment process, and using smoke generated by the secondary thermal cracking device to optimize the upstream treatment process. On the basis of a burning method, the secondary thermal cracking device is added to recycle waste generated in the burning process. The method has the advantagesthat oil content of the oil sludge is reduced, and the whole process is free of secondary pollution.

Description

Technical field: [0001] The invention belongs to the technical field of oil sludge treatment, and in particular relates to a harmless, resourceful and integrated treatment method for oil sludge. technical background: [0002] With the increasing amount of oil extraction, the harm of oil sludge to the environment is becoming more and more serious. It is estimated that the oil sludge produced by major oil fields in the country will be as high as millions of tons every year, resulting in a large amount of crude oil deposited in the oil sludge, resulting in a huge waste of oil resources. At the same time Long-term landfill will cause serious harm to the surrounding environment. In order to treat the oil sludge harmlessly, the following methods are often used: [0003] (1) Simple processing [0004] Landfill oily sludge directly or after solidification. This method has both wasted precious energy wherein, also may cause environmental pollution. [0005] (2) Extraction method ...
