Problems solved by technology

[0003] At present, waste engine oil is mostly regenerated or produced diesel through acid-base washing or high-temperature fission. Acid-base washing requires a large amount of highly corrosive chemical raw materials, and the filtered sediment is a secondary pollutant, which is likely to cause secondary pollution. , the processing cost is high; the high temperature above 400°C required for fission requires energy support, which does not achieve the purpose of saving energy and consumes a lot of financial and material resources, the economic benefit is low, and the environmental protection is of little significance

Embodiment 1

[0023] Let the waste engine oil stand for 24 hours, filter off the surface scum and bottom sediment, and then filter and absorb to remove suspended impurities. The above treated waste engine oil and water are mixed and soaked at a volume ratio of 1:0.2, and stirred vigorously until an emulsion is formed so that the waste engine oil loses its viscosity. The emulsion and water are blended and washed at a volume ratio of 1:2, and left to stand for 2 hours to separate layers, and the lower layer of dirty liquid is filtered off, and the upper layer and water are mixed and washed at a volume ratio of 1:1. The steps of dissolving and washing, and standing to filter the lower layer of dirty liquid until the lower layer of dirty liquid is milky white; in the process of water-miscible washing and standing for stratification, the colloid, ash, pigment and other impurities in the waste engine oil enter In the water, and due to the high density, it settles down, and finally forms the lower...

Embodiment 2

[0027] Let the waste engine oil stand for 12 hours, filter off the surface scum and bottom sediment, and then filter and absorb to remove suspended impurities. Mix and soak the above-mentioned waste engine oil and water at a volume ratio of 1:0.7, add an emulsifier (glyceryl monostearate) with a volume of 0.1% to 2% of the waste engine oil, and stir until an emulsion is formed to make the waste engine oil lose viscosity. The emulsion and water are blended and mixed with water at a volume ratio of 1:5 for washing, and allowed to stand for 4 hours to separate layers. The step of removing the dirty liquid in the lower layer until the dirty liquid in the lower layer is milky white; in the process of water-miscible washing and standing stratification, the colloid, ash, pigment and other impurities in the waste engine oil enter the water, and due to the higher density Large precipitates come down, eventually forming the lower layer of dirty liquid. The supernatant was allowed to s...

Embodiment 3

[0030] Let the waste engine oil stand for 16 hours, filter off the surface scum and bottom sediment, and then filter and absorb to remove suspended impurities. The above treated waste engine oil and water are mixed and soaked at a volume ratio of 1:1.5, and stirred vigorously until an emulsion is formed so that the waste engine oil loses its viscosity. The emulsion and water are blended and mixed with water at a ratio of 1:7 by volume, washed, allowed to stand for 6 hours to separate layers, and the lower layer of dirty liquid is filtered off. The step of removing the dirty liquid in the lower layer until the dirty liquid in the lower layer is milky white. During each cross-washing process, 0.1% to 3% of the volume of the waste engine oil is added as an active agent (nonylphenol polyoxyethylene ether) to promote the colloid, ash, pigment and other impurities in the waste engine oil to enter the water, and finally A bottom layer of foul liquid is formed. The supernatant was a...

Abstract

The invention discloses a method of preparing a high thermal-energy fuel or a diesel additive. The method includes the steps of pre-treating waste engine oil, performing emulsification with water, performing cross-dissolution washing with water repeatedly to take away colloids, ashes, pigments and other impurities from the waste engine oil, and finally modifying layered oil to form the high thermal-energy fuel or the diesel additive. The high thermal-energy fuel is high in combustion heat energy and has important application value. In addition, the diesel additive is good in intersolubility with diesel, and has the effects of improving power, promoting sufficient combustion, being good in cleaning and dispersion, and lubricating and protecting an engine. The method is easy to carry out and mild in conditions, is good in economic benefit and is suitable for practical application.

Description

technical field [0001] The invention relates to a regeneration process of waste engine oil, in particular to a high-calorie fuel or diesel additive and a method for preparing the above-mentioned product from waste engine oil. Background technique [0002] Waste engine oil refers to the waste lubricating oil replaced from various machinery, vehicles, ships, etc., due to impurities such as dust, other miscellaneous oils, and metal powder produced by mechanical wear and tear during use, the color becomes black, the viscosity increases and It gradually deteriorates, producing organic acids, colloids, etc., making it difficult to continue to use. A large amount of waste engine oil is produced every year and discarded as waste, causing environmental pollution and wasting resources. If waste engine oil can be recycled, it will produce huge social and economic benefits. [0003] At present, waste engine oil is mostly regenerated or produced diesel through acid-base washing or high...
