Embodiment 1
[0025] Embodiment 1: a kind of method utilizing waste oil processing liquid fuel oil, comprises the following steps:
[0026] Weigh 50 parts of waste metal processing oil, 20 parts of waste emulsified oil, and 20 parts of waste lubricating oil in parts by weight, fully stir them evenly, and obtain mixed oil; wherein the waste metal processing oil includes metal rolling oil, metal drawing oil, mechanical cleaning oil, etc. A mixture of oils; waste emulsified oil is waste emulsified oil produced during metal machining, and waste lubricating oil is a mixture of waste internal combustion engine oil, waste hydraulic oil, waste gear oil and waste transformer oil.
[0027] Add 0.1% quaternary ammonium salt in the total weight of mixed oil, stir for 10-30 minutes; then add 0.5% concentrated sulfuric acid (98%) in the total weight of mixed oil, let stand at room temperature for 30-60 minutes, break the emulsion, filter to remove heavy metals and other Impurities; then add diatomaceous ...
Embodiment 2
[0032] Embodiment 2: a kind of method utilizing waste oil processing liquid fuel oil, comprises the following steps:
[0033] Take by weight 45 parts of waste metal processing oil, 25 parts of waste emulsified oil, and 30 parts of waste lubricating oil, fully stir to obtain mixed oil; wherein the waste metal processing oil is metal rolling oil and metal drawing oil; waste emulsification Oil is waste emulsified oil produced during metal machining, and waste lubricating oil is a mixture of waste internal combustion engine oil and waste hydraulic oil.
[0034] Add 0.5% quaternary ammonium salt by total weight of mixed oil, stir for 30 minutes; then add 2.5% concentrated sulfuric acid (sulfuric acid content 98%) by total mixed oil, let stand at room temperature for 60 minutes, break emulsion, filter to remove heavy metals and other impurities; then While stirring, add 3% diatomaceous earth of the total weight of the mixed oil for adsorption and decolorization; press filter under 2...
Embodiment 3
[0036] Embodiment 3: a kind of method utilizing waste oil processing liquid fuel oil, comprises the following steps:
[0037] Weigh 40 parts of waste metal processing oil, 20 parts of waste emulsified oil, and 36 parts of waste lubricating oil in parts by weight, fully stir them evenly, and obtain mixed oil; wherein waste metal processing oil is mechanical cleaning oil; waste emulsified oil is metal mechanical processing process The waste emulsified oil produced in the waste lubricating oil is a mixture of waste internal combustion engine oil and waste transformer oil;
[0038] Add 0.3% quaternary ammonium salt in the total weight of mixed oil, stir for 10-30 minutes; then add concentrated sulfuric acid (98%) with 1% total weight of mixed oil, let stand at room temperature for 30-60 minutes, break the emulsion, filter to remove heavy metals and other impurities ; Then add diatomite with 2% total weight of mixed oil while stirring, decolorize by adsorption; press filter at 1MPa...
