Embodiment 1
[0022] Step S1: Put the waste turbine oil in a settling tank, heat the oil to 45° C., settle for 6 hours, and discharge the settled particles to obtain oil A.
[0023] Step S2: Add oil A to the centrifugal oil filter, turn on the power, adjust the rotation speed of the oil filter to 7000r / min, centrifuge at this rotation speed for 40min, and obtain oil B.
[0024] Step S3: Put the coarse-pored silica gel in a constant temperature drying oven and dry at 105°C for 2 hours, add coarse-pored silica gel with a weight equal to 8% of the waste oil to the adsorption tank, add oil B to the adsorption tank, and preheat the oil temperature to 40°C, start the motor to stir, the stirring speed is 100r / min, the stirring time is 35min, and stand still for 1h after stirring to obtain oil C.
[0025] Step S4: Take 4 sheets of alkaline filter paper and dry them in a constant temperature drying oven at 100° C. for 2 hours. Add oil C to the plate and frame filter press, preheat the oil temperatu...
Embodiment 2
[0029] Step S1: Put the waste turbine oil in a settling tank, heat the oil to 50°C, settle for 5 hours, and discharge the settled particles to obtain oil A;
[0030] Step S2: Add oil A to the centrifugal oil filter, turn on the power, adjust the rotation speed of the oil filter to 8000r / min, and centrifuge at this rotation speed for 35min to obtain oil B;
[0031] Step S3: Put the coarse-pored silica gel in a constant temperature drying oven and dry at 110°C for 2 hours, add coarse-pored silica gel with a weight equal to 10% of the waste oil to the adsorption tank, add oil B to the adsorption tank, and preheat the oil to 45°C, start the motor to stir, the stirring speed is 110r / min, the stirring time is 30min, after the stirring is finished, let stand for 1.5h, and oil C is obtained.
[0032] Step S4: Take 3 pieces of alkaline filter paper and dry them in a constant temperature drying oven at 100° C. for 3 hours. Add oil C to the plate and frame filter press, preheat the oil ...
Embodiment 3
[0036] Step S1: Put the waste turbine oil in a settling tank, heat the oil to 40° C., settle for 7 hours, and discharge the settled particles to obtain oil A.
[0037] Step S2: Add oil A to the centrifugal oil filter, turn on the power, adjust the rotation speed of the oil filter to 9500r / min, centrifuge at this rotation speed for 40min, and obtain oil B.
[0038] Step S3: Put the coarse-pored silica gel in a constant temperature drying oven and dry at 120°C for 1.5 hours, add coarse-pored silica gel whose weight is 6% of the waste oil weight into the adsorption tank, add oil B to the adsorption tank, and preheat the oil temperature to 48°C, start the motor to stir, the stirring speed is 80r / min, the stirring time is 45min, and stand for 2h after stirring to obtain oil C.
[0039] Step S4: Take 2 sheets of alkaline filter paper, and dry them in a constant temperature drying oven at 100° C. for 3.5 hours. Add oil C to the plate and frame filter press, preheat the oil temperatu...
