Description
Technical field
The invention belongs to field of renewable energy；Be related to a kind of preprocess method of biodiesel raw material, it is especially a kind of by
The preprocess method for the ROLLING OIL Preparation of Biodiesel from Waste Oils raw material that metallurgical cold rolling product generates.
Background technique
In metallurgy industry, ROLLING OIL used in cold rolling mill cold-rolled products is frequently with oil emulsion or animal and plant fat as lubrication
Agent and coolant.Using after a certain period of time, cooling and lubricating effect declines, material oxidation deterioration.When the impurities accumulation of generation is to one
After determining degree, it is necessary to use the ROLLING OIL before new ROLLING OIL replacement.Replaced waste rolling oil be substantially include yin-
Nonionic surfactant, grease, solid greasy filth (main component is ferric oxide particles) and water micro emulsion.This microemulsion
Liquid has higher stability, and the waste rolling oil appearance of this micro emulsion is reddish brown, or is dark thick shape, volume compared with
Greatly, moisture content is 20% or more, and specific gravity is close to 1.In a heated condition, organic matter contained by waste rolling oil is readily volatilized, generates
Strong smog and pungent odour belongs to the hazardous waste that country forbids discharge to pollute the environment.Total comes
It sees, waste rolling oil has the double characteristic of pollution and resource, implement appropriate recycling, regeneration treatment and recycling to it,
It is the inexorable trend for the sustainable development for realizing that resource maximizes and environmental pollution minimizes.
Before, most domestic waste oil regeneration factory regenerates waste rolling oil using sulfuric acid backward in technique-carclazyte method
Processing.This technique decolorizing effect is obvious, stable product quality.However, due to using a large amount of concentrated sulfuric acid to connect with aqueous waste oil

Circulating-heating is carried out in the rectifying column of part, is evaporated under reduced pressure, then condensing recovery.The circulation that ROLLING OIL may be implemented in this technique makes
With, and save the cost.
Chinese patent application CN200810141346.8 discloses a kind of process lubrication coolant oil regeneration method.This method is adopted
It is different using each component boiling range in miscella with rotating scraped film evaporator, it is condensed after being distilled by heating under reduced pressure, by technological lubrication
Cooling purifies out from miscella to be utilized again.
Chinese patent application CN201510663599.1 discloses a kind of recovery processing process of the oil of useless rolling, including with
Lower step: filtering waste rolling oil；Extractant and flocculant and isolated first supernatant is added；Adsorbent is added simultaneously thereto
Separation, obtains the second supernatant；The component between 80~100 DEG C and 240~360 DEG C is collected in vacuum distillation respectively.
The pollution of above-mentioned anacidity waste oil regeneration technology is small, and yield is high, good product quality, achieve certain economic benefit but
Above-mentioned technology still remains following shortcoming:
(1) way of distillation equipment investment is big, and cost is high；Distillation process needs high temperature, and temperature is difficult to control, and it is high to consume energy.
(2) extractant and flocculant belong to chemical reagent, and investment ratio is big, increase production cost, and bring at waste water
The difficulty of reason.
