Abstract
The invention relates to a regeneration method for waste rolling oil, which is most suitable for the regeneration of the waste rolling oil in a steel plant or a cold rolling plant. The method comprises the following steps: firstly, adding an alkali to the waste rolling oil; secondly, adding polyacrylamide to the waste rolling oil; and finally, performing centrifugal separation. The method can recover oil radically, is simple and easy, and has very good social benefit and economic benefit.
Description
Technical field
The present invention relates to a kind of renovation process of waste rolling oil, it is best suited for the regeneration of steel-making cold rolling mill waste rolling oil, belongs to a kind of oil separating method.
Background technology
Be extensive use of ROLLING OIL in metallurgical industry, the annual whole nation all has a large amount of waste rolling oils to produce.The problem of utilizing of waste rolling oil is a great problem of puzzlement enterprise always for many years.Most of enterprise burns waste rolling oil or sells when waste oil as oil fuel, contaminate environment not only, and caused the significant wastage of resource.
The regeneration of waste rolling oil mainly is to remove lubricating oil component in the waste oil and the high-carbon component in the portions additive, removes the colloid in the oil, and bad component such as bituminous matter reduces oxidisability, increases stability.
Summary of the invention:
The purpose of this invention is to provide a kind of economical and effective, simple and easy to do waste rolling oil renovation process.
Technical scheme of the present invention:
A kind of renovation process of waste rolling oil.
Waste rolling oil is mixed stirring with a certain amount of alkali, add a certain amount of polyacrylamide then and continue to stir, it is centrifugal at last mixture to be put into whizzer, and mixture produces layering, isolates the upper strata and promptly gets the regenerated ROLLING OIL.
The concrete practice of the present invention is:
(1) consumption of alkali is the 1%-5% of waste oil consumption, preferably 2%-3%.Alkali can be mixed with certain density alkali lye and use.
(2) alkali can be sodium hydroxide, potassium hydroxide or other alkali.The present invention's technical scheme preferably is a sodium hydroxide, because sodium hydroxide economy is easy to get.
(3) stirring can make reaction carry out smoothly, as long as stirring velocity and reaction times can make the solution mixing, sufficient reacting gets final product.
(4) polyacrylamide is a cationic-type polyacrylamide.
(5) whizzer is a supercentrifuge, and rotating speed is at 5000-10000rpm/min, centrifugal 2-10 minute.
Positive beneficial effect of the present invention:
The present invention makes full use of waste rolling oil, both economizes on resources, and helps environment protection again; Separation method technology is rationally simple, invests little; Separate fully good separating effect.
Embodiment:
The present invention carries out in the laboratory, below by example the present invention is elaborated.
Example 1:
(1) get waste rolling oil 20ml, adding concentration is the sodium hydroxide 2ml of 5M, stirs 2 minutes.
(2) the cationic-type polyacrylamide 1ml of adding 0.04% continues to stir 10 minutes.
(3) with whizzer under 10000rpm/min centrifugal 3 minutes, collect upper strata oil and promptly get the regenerated ROLLING OIL.
Example 2:
(1) get waste rolling oil 100ml, adding concentration is the sodium hydroxide 10ml of 5M, stirs 3 minutes.
(2) the cationic-type polyacrylamide 5ml of adding 0.04% continues to stir 10 minutes.
(3) with whizzer under 8000rpm/min centrifugal 4 minutes, collect upper strata oil and promptly get the regenerated ROLLING OIL.
Example 3:
(1) get waste rolling oil 1000ml, adding concentration is the sodium hydroxide 50ml of 10M, stirs 2 minutes.
(2) the cationic-type polyacrylamide 10ml of adding 0.2% continues to stir 5 minutes.
(3) with whizzer under 7000rpm/min centrifugal 5 minutes, collect upper strata oil and promptly get the regenerated ROLLING OIL.
Claims (5)
1, a kind of renovation process of waste rolling oil, it is characterized in that: waste rolling oil is mixed stirring with a certain amount of alkali, add a certain amount of polyacrylamide then and continue to stir, it is centrifugal at last mixture to be put into whizzer, mixture produces layering, isolates the upper strata and promptly gets the regenerated ROLLING OIL.
2, according to the renovation process of the described a kind of waste rolling oil of claim 1, it is characterized in that: the consumption of alkali is the 1%-5% of waste rolling oil consumption, preferably 2%-3%.
3, according to the renovation process of the described a kind of waste rolling oil of claim 1, it is characterized in that: alkali can be sodium hydroxide, potassium hydroxide or other alkali.
4, according to the renovation process of the described a kind of waste rolling oil of claim 1, it is characterized in that: polyacrylamide is a cationic-type polyacrylamide.
5, according to the renovation process of the described a kind of waste rolling oil of claim 1, it is characterized in that: whizzer is a supercentrifuge, and rotating speed is at 5000-10000rpm/min.
