Description
Technical field
The invention belongs to waste transformer oil reutilization technology field, particularly a kind of waste transformer oil recycling side
Method.
Background technology
With the development of power industry, waste transformer oil wide material sources, enormous amount.And at present to waste transformer oil
Processing do not have highly effective measure, sold for nothing generally as waste product；Even some waste oil is direct
Topple over, cause very big environment hidden danger.
The thermodynamically stable aqueous colloidal dispersion that microemulsion is made up of surfactant, cosurfactant, oil and water
System, has extremely low interfacial tension and stronger solubilising power, at present in fields such as greasy dirt cleaning, tertiary oil recovery, medal polish
Have broad application prospects.Therefore, develop discarded transformer oil and microemulsion is made as oil phase, both solve discarded change
The processing of depressor oil, is recycled, can produce huge economic benefit and social value again.
The content of the invention
The purpose of the present invention is in view of the shortcomings of the prior art, to propose a kind of waste transformer oil reuse method.
The present invention solves its technical problem and takes following technical scheme to realize：
A kind of waste transformer oil reuse method, it is as follows that the method comprising the steps of：
(1) by anion surfactant and nonionic surfactant according to mass ratio 1:1 is re-dubbed compositional liquor, then
Aqueous surfactant solution is made in stirring after compositional liquor is weighed into water；
(2) cosurfactant is added into aqueous surfactant solution made of step (1), stirred to transparent and homogeneous；
(3) discarded transformer oil is gradually added into aqueous surfactant solution made of step (2), stirred to homogeneous
Transparent, it is 10-20wt% to finally give compounding liquid hold-up, and cosurfactant content is 2.5-5wt%, and waste transformer oil contains
It is the microemulsion of water to measure as 1-5wt%, remaining phase.
Moreover, anion surfactant is AES in the step (1), nonionic surfactant be peregal 15 or
One kind in AEO-7.
Moreover, cosurfactant is n-butanol in the step (2).
The advantages and positive effects of the present invention are：
1st, the present invention recycles discarded transformer oil, and microemulsion has been made, and the microemulsion is thermodynamic stable system,
Outward appearance transparent and homogeneous, there is relatively low interfacial tension and preferable compatibilization ability, while there are preferable long-time stability and heat
Stability, it is easy to store and transports, suffers from preferably applying in fields such as medal polish, tertiary oil recovery, the cleanings of equipment greasy dirt
Prospect.
2nd, the technology of the present invention is simple for process, is easy to field application.
