Abstract

The invention relates to a method for processing liquid fuel oil by using waste oil. The method comprises the following steps of: in part by weight, weighing 40 to 50 parts of waste metal processing oil, 20 to 30 parts of waste emulsifying oil and 20 to 40 parts of waste lubricating oil, and stirring the components uniformly and sufficiently to obtain mixed oil; adding a cationic surfactant and concentrated sulfuric acid into the mixed oil, performing emulsion breaking, and filtering the mixture to eliminate heavy metals and other impurities; adding diatomaceous earth into the mixture to perform adsorption bleaching, and performing filter pressing to separate liquid and a solid mixture; adding isopropanol to separate out oil and water; and adding a flash point modifier and an antioxidant into the separated oil, and modulating the mixture to obtain the liquid fuel oil. The method has a simplified process, can be performed at normal temperature and generates fewer waste products; the waste oil can be combusted sufficiently after being processed, and an exhaust gas contains few harmful gases; and the fuel oil can be widely used as a fuel for power generation by electric power plants, ship boilers, heating furnaces, metallurgical furnaces and other industrial furnaces. The method realizes the full utilization of the waste oil and has good economic and social benefits.

Description

1. Technical field: [0001] The invention relates to a method for recycling waste oil, in particular to a method for processing liquid fuel oil with waste oil. 2. Background technology: [0002] Waste oil is a common waste in daily life. After proper treatment, waste oil can be turned into treasure and reused. Many waste oils contain light fuel oil, such as waste internal combustion engine oil contains a small amount of light diesel oil and gasoline, machinery factory cleaning oil contains a large amount of light diesel oil and kerosene, and many oil washing tanks also contain a large amount of light diesel oil. There will also be situations where diesel oil is mixed with gasoline, engine oil, etc. to become waste oil. [0003] There are many types of waste lubricating oil, including waste internal combustion engine oil, waste hydraulic oil, waste gear oil and waste transformer oil. These oils are generally heavy oils with high viscosity and are not suitable for direct use a...
