Abstract

The invention discloses a treatment method and device for oil sludge. The method comprises the following steps: mixing and pressing oil sludge, charred coal, coking flash ash and tar residue into a ball, mixing coking coal into the coal ball to perform coking, treating the oil sludge through a coking oven, and ensuring that oil in the oil sludge is converted into coal gas for utilization, components, such as iron and calcium, are cured into coke, enter a blast furnace with the coke and are reduced in the blast furnace and fused into molten iron to be utilized, so as to realize completely harmless disposal. The treatment method is simple, and harmless disposal of oil sludge is realized; the problem that oil sludge water treatment is difficult to dispose and high in disposal cost is solved;the method meets the national policies on environmental protection and cyclic economy, and has good social benefit and environmental protection and energy saving benefit.

Description

technical field [0001] The invention relates to a treatment method and device for oil sludge, belonging to the technical field of environmental protection. Background technique [0002] Oily wastewater and waste emulsion will produce sludge during the treatment process. The sludge is composed of water, oil and solids. It is a black sticky liquid. It is included in the "National List of Hazardous Wastes". It is a hazardous waste and must be disposed of in a harmless manner. If it is sent to a unit with hazardous waste disposal qualifications for disposal, on the one hand, the disposal cost will be higher, and on the other hand, the valuable components in the oil sludge will not be recovered, resulting in a waste of resources. [0003] For example, since the oily wastewater treatment system of a steel plant was put into operation, 15 tons of sludge has been produced every day. The sludge is black and sticky, liquid in hot state, and viscous after cooling. It consists of 70% w...
