Oily sludge cleaning, reducing and purifying resource regeneration process method

Abstract

The invention discloses a technological method for cleaning oily sludge and regenerating resources, which comprises the following steps: 1) cleaning: I) stirring oil: spraying hot oil by using a cleaning machine to crush and dissolve sludge and solidified oil around an oil tank, and stirring to disperse the sludge and solidified oil; iI, cleaning with the same oil; iII, washing with warm water; 2) decrement: performing screening, slurrying, hardening and tempering, high-frequency pulse cleaning and centrifugal solid-liquid separation treatment on the oil sludge sand; 3) purification: carrying out purification treatment on the liquid product, wherein the purification treatment comprises oil-water separation, dirty oil purification and sewage treatment; and 4) resource regeneration: carrying out cold-state extraction, auxiliary molding and high-temperature sintering treatment on the oil sludge. According to the invention, the whole process from the cleaning of the sludge in the closed space to the resource regeneration of the terminal is completed, the cleaning-reduction-purification-resource regeneration treatment of the oil-containing sludge in the closed space is realized under the condition of not stopping production, the normal production is ensured, the purified crude oil can be used as yield-increasing crude oil, and the economic benefit is greatly improved.

Description

technical field [0001] The present invention relates to the technical field of comprehensive disposal of oily sludge, and more particularly to a process method for oily sludge removal and net resource regeneration. Background technique [0002] Confined space cleaning is an integral part of operations in the petroleum and petrochemical industries. At present, the oily sludge disposal method for confined spaces is a single-stage, single-process service, with a clear division of labor and a certain scope for each process. In addition, increasingly stringent legislation and regulations regarding the environment, worker safety and health are placing enormous pressure on industries. As a result, more and more owners and managers are looking for automated, non-invasive methods of containment cleaning. In addition, it is ideal to combine confined space stripping and cleaning while eliminating degassing requirements. [0003] However, various service processes in the process are ...
