Problems solved by technology

[0003] Due to the huge amount of oily sludge produced in the process of oil exploitation and refining, a medium-sized oil field produces more than 200,000 tons of oily sludge every year. Under the background of extensive management for many years, the disposal method is mostly landfill. Burying or burning not only takes up a lot of land, but also causes great damage to the environment and serious pollution

Abstract

The invention discloses a continuous treatment method of oily sludge. The continuous treatment method comprises a special continuous treatment system. The special continuous treatment system structurally comprises a dehydration unit for primarily dehydrating the oily sludge, a pyrolysis unit for pyrolyzing the primarily dehydrated oily sludge into oily steam and solid impurities and a recovery unit for separately recovering oil-containing steam and solid impurities, wherein the dehydration unit, the pyrolysis unit and the recovery unit are sequentially connected through a conveying pipeline or / and a conveying device. The continuous treatment system disclosed by the invention is reasonable in structure; and the treatment method is scientific, can realize whole-course zero emission in the oily sludge treatment process, is carried out strictly according to the treatment specifications of the Ministry of Environmental Protection on related three wastes (wastewater, waste gas and waste residues), and meets the overall requirements of three processes (harmlessness, reduction and recycling) in the treatment process.

Description

technical field [0001] The invention relates to the treatment of oily sludge, in particular to a continuous treatment method for oily sludge. Background technique [0002] Oily sludge is a hydrocarbon organic matter containing a large amount of petroleum hydrocarbons produced in the process of oil extraction and refining. It is an emulsified viscous substance formed by asphaltene, colloid, sediment, floc, waste water and waste residue and some other organic and inorganic substances disorderly mixed together, which contains stupid, phenol, anthracene, pyrene It is a strong carcinogenic and toxic substance with a particularly strong impact on the environment. It was once listed as hazardous waste by the Ministry of Environmental Protection and was strictly controlled. [0003] Due to the huge amount of oily sludge produced in the process of oil extraction and refining, a medium-sized oil field produces more than 200,000 tons of oily sludge every year. Under the background of ...
