Abstract
The invention discloses an absorbent for refining and de-coloring waste transformer oil, which is prepared by mixing silver nitrate, copper sulfate and aluminum chloride according to a mass part ratio of 0.1: 1: 100, adding water for soaking the mixed material, completely blending the mixed solution and drying the mixture in an oven for use. In the invention, the silver nitrate, copper sulfate and aluminum chloride are used as the absorbent of a reduction refining system, and a natural precipitation method is adopted to quickly and efficiently remove harmful components in the waste transformer oil and perform de-coloring, so that all indexes can reach or approximate the criteria of new oil. The absorbent has the advantages that: the used amount is small, discharge is small, environmental pollution can be reduced, and the environment and the body health of workers can be protected.
Description
Technical field
The present invention relates to a kind of adsorbent, relate in particular to and a kind of useless transformer oil make with extra care the adsorbent that decolours, belong to the chemical industry technical field.
Background technology
Operating transformer oil is because of the effect of the factors such as temperature, electric field, moisture, impurity and metallic catalyst that are subjected to air, chemical reactions such as oxidation, cracking take place, it is rotten gradually to be in operation, generate oxidation products such as a large amount of peroxide and alcohol, aldehyde, ketone, acid, generate insoluble matters such as greasy filth again through condensation reaction.Transformer oil to deterioration need reclaim the processing of regenerating.For serious deterioration transformer oil treatment process sulfuric acid-carclazyte method, Acid-Base-carclazyte method etc. are arranged at present.These processing methods are remarkable for every index effect of improvement and the useless transformer oil of recovery, can make waste oil regeneration and the application of putting into production.But these methods can produce a large amount of acid sludges and alkali lye, be difficult to handle and utilize, environment is caused serious pollution, and the high harm of these renovation process processing costs staff is healthy, used by country's restriction, and progressively be eliminated, now issue decree abroad and forbidded strictly to use these renovation process.
Summary of the invention
In order to address the above problem, the object of the present invention is to provide a kind of adsorbent that decolours that useless transformer oil make with extra care.Can make with extra care the decolouring absorption regeneration to the transformer oil of serious deterioration, speed is fast, and is effective, and can reduce regeneration cost, and the adsorbent consumption is few, and discharging is few, can reduce environmental pollution.
The technical solution adopted for the present invention to solve the technical problems is: a kind of useless transformer oil make with extra care the adsorbent that decolours, it is the mixture of silver nitrate, copper sulphate and aluminium chloride.After silver nitrate, copper sulphate, aluminium chloride mixed according to a certain percentage, add entry and flood, mix the back fully, can use after the oven dry in drying in oven.The mixed proportion of described silver nitrate, copper sulphate, aluminium chloride is 0.1 ﹕, 1 ﹕ 100 according to mass parts.Its principle is to use silver nitrate, copper sulphate as reducing catalyst, and aluminium chloride makes silver nitrate, copper sulphate be attached to a kind of adsorbent on its surface as carrier simultaneously as finishing agent.Can fast, efficiently adsorb objectionable impurities in the useless transformer oil.
The invention has the beneficial effects as follows: owing to be to adopt silver nitrate, copper sulphate, aluminium chloride to make with extra care the adsorbent of system as reduction, the employing natural sedimentation method can be fast,
The efficient harmful components of removing in the useless transformer oil, and decolour, its every index can reach or approaching new oil standard.This adsorbent cost is by 4000 yuan/ton; average regeneration handle useless transformer oil per ton only need with oil heavy 1%-1.6%, amount to and handle one ton of useless transformer oil cost and only need about 100 yuan, regeneration cost is low; produced simultaneously discarded object is few, helps protecting environment and staff healthy.
The specific embodiment
A kind of useless transformer oil make with extra care the adsorbent that decolours, it is the mixture of silver nitrate, copper sulphate and aluminium chloride.After silver nitrate, copper sulphate, aluminium chloride mixed according to a certain percentage, add entry and flood, mix the back fully, can use after the oven dry in drying in oven.The mixed proportion of described silver nitrate, copper sulphate, aluminium chloride is 0.1 ﹕, 1 ﹕ 100 according to mass parts.
Using method: use this adsorbent, adopt natural sedimentation method to leach fresh oil.
Result of use: index contrasted as following table before and after waste oil regeneration was handled:
| Test item | Fresh oil (standard) | Before the processing | After the processing |
| Color | Transparent | Sepia | Faint yellow |
| Dielectric dissipation factor (90 ℃) | 0.005 | 4.00 | 0.001 |
| Water soluble acid PH | ＞5.4 | 4.0 | 6.0 |
| Acid number mgKOH/g oil | 0.03 | 0.34 | 0.002 |
| Specific insulation Ω m | 6×10 10 | 2×10 8 | 6.5×10 12 |
Claims (2)
1. useless transformer oil make with extra care the adsorbent that decolours for one kind, it is the mixture of silver nitrate, copper sulphate and aluminium chloride, it is characterized in that: after silver nitrate, copper sulphate, aluminium chloride are mixed according to a certain percentage, adding entry floods, mix the back fully in drying in oven, can use after the oven dry.
2.
According to claim 1ly a kind of useless transformer oil make with extra care the adsorbent that decolours, it is characterized in that: the mixed proportion of described silver nitrate, copper sulphate, aluminium chloride is 0.1 ﹕, 1 ﹕ 100 according to mass parts.
