Abstract

The invention provides modified fuel slurry of oily solid waste and a preparation method thereof. The fuel slurry comprises, by weight, 50-80% of the oily solid waste, 10-50% of modifying agents and the balance water. The preparation method of the modified fuel slurry comprises the steps of (1), weighing the modifying agents and the water according to the weight proportion, adding the modifying agents and the water into a reaction still with the stirring function, stirring the modifying agents and the water uniformly in an airtight mode at normal temperature and normal pressure for 0.5 hour to 1 hour and then obtaining a modifying agent water solution; and (2), weighing the oily solid waste according to the weight proportion, adding the oily solid waste into the modifying agent water solution obtained in the step (1), stirring the mixture uniformly in an airtight mode at normal temperature and normal pressure for 0.5 hour to 1 hour and then obtaining the light brown modified fuel slurry of the oily solid waste. According to the modified fuel slurry of the oily solid waste and the preparation method thereof, the problems that in the prior art, reclamation of the oily solid waste is high in energy consumption and does not meet the environmental emission standard are solved, and resource utilization of the oily solid waste is realized through the modified fuel slurry.

Description

technical field [0001] The invention belongs to the technical field of resource utilization of oil-containing solid waste, and in particular relates to a fuel slurry modified by oil-containing solid waste and a preparation method thereof. Background technique [0002] Oily solid wastes are combustible oily solid wastes in the process of oil and gas exploitation, mainly including oil-based drilling cuttings and waste mud, oil storage tank bottom sludge, ground oil, oil sands and other oily solid wastes from different sources. Oily solid waste is a typical hazardous waste, which has been included in the national list of hazardous waste. If harmless treatment and disposal are not carried out, pollutants will migrate to soil and groundwater through diffusion, and enter the ecological environment, causing serious environmental hazards. At present, incineration, pyrolysis recovery, extraction recovery and other methods are mainly used at home and abroad for treatment. These metho...
