[Principle]Generally,we use the oil on the machine is the purognostics oil, it is a kind of product which is obtained by the heavy tar fraction petroleum reduced pressure and distillation.The so-called waste oil, first, the machine oil mixed in impurities metal powder and the moisture content,oils and the part attrition produced; second, referred to the machine oil to deteriorate gradually, has produced the organic acid, the sol subsidence, distillation, acid pickling, soda wash, filtration except the machine oil in impurity.
[Operation](1) subsidence settles the used oil, and the asphalt shape material.The waste oil regeneration, is with methods and so on causes the impurity to drop separates.The settling time decided by the oil material and the oil temperature.The oil temperature is higher, the viscosity is smaller, the impurity is easier to drop, the settling time is shorter.
(2) distillation puts in process subsidence processing after the settling waste oil in the distilling flask.Installs the distilling apparatus, the heating carries on the atmospheric distillation.In 180℃ runs down is the gasoline, 180~360℃ the fraction is the diesel oil, stays behind is the machine oil.If in the known waste oil does not have impurities and so on gasoline, diesel oil, may save this step the operation.
(3) acid pickling the subsidence, the distillation machine oil puts in a big beaker, heats up 35℃, joining slowly under the agitation occupies the machine oil volume 6~8% strong sulfuric acid (to add approximately in 30 minutes).By now, the strong sulfuric acid with waste oil in sol, the asphalt shape impurity and so on had the sulfonation reaction.In order to after these sulfonation impurity, joins again accounts for the machine oil volume 1% 10% burns the alkaline solution, plays the coagulating agent role, the acceleration impurity lamination.After the alkalizing stirs 5 minutes, settles period of time, appears the obvious lamination, the upper formation oil assumes Huang Lvse, does not have impurities and so on black pellet.
