Background

The oil sludge refers to a large amount of oil-containing sludge generated in the processes of crude oil exploitation, gathering and transportation, refining, oil-containing sewage treatment and the like. Because the compound contains poisonous and harmful substances such as anthracene, pyrene, phenols, benzene series, heavy metals and the like, the compound is listed as dangerous waste by the nation and is brought into the dangerous waste management category. At present, due to the fact that oil sludge is wide in production range, complex in type and component, and extremely unstable in oil content of 10-50%, impurity components, particle size, physical state, water content and oil content in the sludge are also extremely unbalanced, and the problems that oil sludge treatment equipment is not stable in operation, cannot continuously operate, and is high in equipment failure rate are caused. Therefore, before the oily sludge is treated, the pretreatment of the oily sludge is a precondition for ensuring stable, efficient and low-energy operation of subsequent sludge treatment, but most of oil in the oily sludge is solid crude oil, so that the oil is difficult to remove from the sludge at normal temperature, and the sludge with large particle size in the sludge also influences the operation of subsequent sludge treatment equipment. At present, the existing pretreatment device washes oily sludge by using hot water, and adds a medicament to separate crude oil from the sludge, but does not separate sludge with large particle size in the sludge, the sludge with large particle size still remains after the water washing, which can affect the operation of subsequent oil sludge treatment equipment, and the addition of the medicament can cause secondary pollution of the oil sludge, the medicament is difficult to remove in the subsequent treatment process, which can cause greater burden to the environment, and the crude oil in the oil sludge is difficult to recover, which causes resource waste.
