Embodiment 1

[0053] Such as figure 1 shown, including the following steps:

[0054] Step 1, pretreating the waste oil to obtain the pretreated waste oil;

[0055] S1.1. Heating the collected original waste oil to 50°C and then standing still to allow the larger impurity particles to precipitate naturally; then filter to initially filter out the precipitated solid impurities to obtain the waste oil filtrate;

[0056] S1.2, pump the waste oil filtrate treated in S1.1 into the pretreatment tank, and control the temperature in the pretreatment tank at 60°C;

[0057] Then, at a stirring speed of 50r / min, a formic acid solution with a mass concentration of 15% is added to the pretreatment tank at a speed of 1ml / min; wherein, the formic acid quality in the formic acid solution added is obtained by S1.1 10% of the quality of waste oil filtrate;

[0058] After the dropwise addition of the formic acid solution, continue to stir for 30 minutes; then, at a stirring speed of 80r / min, the temperature...

Embodiment 2

[0075] Step 1, pretreating the waste oil to obtain the pretreated waste oil;

[0076] S1.1, heat the collected original waste oil to 70°C and let it stand still to allow the larger impurity particles to precipitate naturally; then filter to initially filter out the precipitated solid impurities to obtain the waste oil filtrate;

[0077] S1.2, pump the waste oil filtrate treated in S1.1 into the pretreatment tank, and control the temperature in the pretreatment tank to be between 62°C;

[0078] Then, at a stirring speed of 53r / min, a formic acid solution with a mass concentration of 12% is added to the pretreatment tank at a speed of 1ml / min; wherein, the formic acid quality in the formic acid solution added is obtained by S1.1 7% of the quality of waste oil filtrate;

[0079] After the dropwise addition of the formic acid solution, continue to stir for 33 minutes; then, at a stirring speed of 76r / min, heat up to 65°C, and feed the pretreatment tank with a mass concentration o...

Embodiment 3

[0096] Step 1, pretreating the waste oil to obtain the pretreated waste oil;

[0097] S1.1, heat the collected original waste oil to 80°C and let it stand still to allow the larger impurity particles to precipitate naturally; then filter to initially filter out the precipitated solid impurities to obtain the waste oil filtrate;

[0098] S1.2, pump the waste oil filtrate treated in S1.1 into the pretreatment tank, and control the temperature in the pretreatment tank to be between 63°C;

[0099] Then, at a stirring speed of 53r / min, a formic acid solution with a mass concentration of 12% is added to the pretreatment tank at a speed of 1ml / min; wherein, the formic acid quality in the formic acid solution added is obtained by S1.1 7% of the quality of waste oil filtrate;

[0100] After the dropwise addition of the formic acid solution, continue to stir for 32 minutes; then, at a stirring speed of 75r / min, the temperature is raised to between 64°C, and a mass concentration of 12% ...

Abstract

The invention provides a device, a method and a lubricating oil for preparing biodegradable lubricating oil from waste oil. The lubricating oil comprises the following parts by weight: 900-1000 parts by weight of base oil; 4-6 parts by weight of barium petroleum sulfonate; nitrogen-containing sulfuric acid 4-6 parts by weight of derivatives; 4-6 parts by weight of polyalphaolefin; 15-25 parts by weight of high-basic calcium sulfonate for complex calcium-based grease; 10-20 parts by weight of sulfur phosphorus secondary alcohol base zinc salt. The method has the following advantages: (1) The preparation process is simple, the yield and purity of the prepared base oil are very high, the lubricating oil prepared thereby has a very high purity, and the efficient recovery and reuse of waste oil is realized. (2) The prepared base oil and lubricating oil have the advantages of high viscosity index, high oxidation stability and good low-temperature fluidity, and have a wide range of uses. (3) The prepared base oil is a biodegradable base oil, which reduces the pollution to the environment after the base oil is used.

Description

technical field [0001] The invention belongs to the technical field of lubricating oil preparation, and in particular relates to equipment and a method for preparing biodegradable lubricating oil from waste oil and lubricating oil. Background technique [0002] Waste oil refers to a series of oil wastes that lose their edible value produced during the consumption of natural vegetable oil and animal fat, and the deep processing of oil, commonly known as gutter oil, swill oil, swill oil, etc. According to expert calculations, the amount of waste oil accounts for 20% to 30% of the total consumption of edible oil. Based on the average annual edible oil consumption in my country of 2100×104t, waste oil is produced every year from 00×104 to 800×104t. Waste oil contains a large amount of organic matter, which has the duality of polluting the environment and recycling. [0003] At present, my country's waste oil has not been rationally utilized. On the contrary, waste oil has bec...
