Dirty oil mud separating method and device

Abstract

The present invention relates to a petroleum processing method and equipment, especially to an oil-bearing sludge separating method and equipment, provides a simple, economical, practical, environment-protecting and pollution-free oil-bearing sludge processing method and equipment, and the method comprises the following procedures: heating the water vapor to the superheated steam with temperature above 500 DEG C with a superheated steam boiler; injecting the superheated steam to the oil-bearing sludge with a speed of 2 mach, the oil-bearing sludge is crushed to small particles after instant colliding; separating the water component and the oil component which are evaporated and sublimed instantly with a cyclone separator; dropping the temperature and fluidifying through water spraying; and extracting the oil product up to standard by the separating of the oil-water separating pot, above 95% oil component in the oil-bearing sludge can be recovered and the oil content of the residue is lower than 5%, the petroleum processing method has the advantages of guaranteeing the quality of the recovered oil product, simple operation and maintenance, broad application that can be applied to varies types of oil-bearing sludge and oil-bearing sand, excellent economic benefit and low cost, the equipment is used for processing the oil-bearing sludge that is generated in the crude oil exploration and exploitation, crude oil transportation and the petroleum refinery wastewater treatment.

Description

technical field [0001] The invention relates to a method and equipment for oil treatment, in particular to a method and equipment for separating sludge, which belongs to environmental protection equipment. Background technique [0002] At present, energy and environmental issues are issues of global concern. The petroleum industry is developing rapidly. With the continuous increase of mining volume, a large amount of oily sludge is produced in the production process. Oily sludge is produced in oil extraction, transportation, refining and oily The oily solid waste produced in the sewage treatment process generally has an oil content of 10%-50%, a water content of 40-90%, and a maximum of 99.9%. In my country's petrochemical industry, an average of 800,000 tons of tanks are produced every year. Bottom sludge, pond bottom sludge, these sludges contain a large amount of benzene series, phenols and other odorous and toxic substances. If they are not treated, they will not only poll...
