Abstract
The invention discloses a recovery method of synthetic oil in the internal part of a transformer. The recovery method comprises the following steps of: judging the content of metal elements in the synthetic oil for judging whether to recover the transformer; and respectively carrying out the following steps on the synthetic oil in transformer to be recovered: heating up to 120 DEG C for the first time, keeping the temperature for 36 hours for the first time after naturally standing and cooling to 110 DEG C, precipitating dirt and impurities, heating up to 120 DEG C for the second time, adding a decolorizing adsorbent and fully stirring, standing at 110 DEG C, keeping the temperature for 8 hours for the second time, and precipitating the impurities. The method is of a clean, environment-friendly, low-cost and rapid processing manner, and the waste clearing and the reuse of effective substances are realized to the greatest extent.
Description
Technical field
The present invention refers to the processing method to transformer in the transformer especially relevant for the recovery of transformer.
Background technology
The manufacturing of transformer needs metal and synthetic oil, especially in the process that it is prepared again, adopts hydrogenation preliminary treatment depickling; Furfural treatment is carried out operations such as denitrogenation, the for example known disclosed technical scheme of invention application CN200810226061.4.
And not only there is external pollution in these artificial oils after long-term use, more can change in inside, produce chemical change.When we scrapped transformer, the processing of this part artificial oil just became subject matter, and a kind of cleaning, environmental protection, low cost processing mode fast need be provided, and realized the cleaning of refuse and the utilization again of active principle to greatest extent.
Summary of the invention
In order to solve the problems of the technologies described above, the present invention provides the recovery method of the inner artificial oil of a kind of transformer, comprising: judge the metal element content in the said artificial oil, transformer is reclaimed judging whether; Artificial oil in the transformer that reclaims for needs carries out respectively: be heated to 120 ℃ for the first time, leave standstill naturally be cooled to 110 ℃ after, be incubated 36 hours for the first time, precipitate dirt impurity; For the second time be heated to 120 ℃, add decolorizing adsorbent and fully stirring, under 110 ℃, leave standstill, be incubated 8 hours, precipitated impurities for the second time.
Because material therefor is little to reclaim, to pollute among the present invention, so this method cleaning, environmental protection, low cost processing mode fast, and realize the cleaning of refuse and the utilization again of active principle to greatest extent.
Embodiment
The present invention provides the recovery method of the inner artificial oil of a kind of transformer, it is characterized in that: judge the metal element content in the said artificial oil, transformer is reclaimed judging whether; Artificial oil in the transformer that reclaims for needs carries out respectively: be heated to 120 ℃ for the first time, leave standstill naturally be cooled to 110 ℃ after, be incubated 36 hours for the first time, precipitate dirt impurity; For the second time be heated to 120 ℃, add decolorizing adsorbent and fully stirring, under 110 ℃, leave standstill, be incubated 8 hours, precipitated impurities for the second time.Remove a large amount of impurity after twice intensification, used time less of while, the pollution of generation is also less.
Concrete, wherein said metal element content is measured as: the said synthetic oil sample of 1) gathering is heated 100 ℃, cooling deposition, elimination impurity; 2) said synthetic oil sample is carried out heat to 300 ℃, to reach ashing; 3) sample after the said ashing is dissolved; 4) adopt full spectrum direct-reading plasma emission spectrometer accurately to measure the content of multiple metallic element.It is many that preferred version of the present invention is measured element, and accuracy is high, can measure the oily medium of variety classes and different content scope, can accurately embody the variation tendency of metal in the oily medium, is convenient to accurate analysis, in time scents a hidden danger.
Wherein also comprise behind the heat tracing in the first time: deviate from the sulfur-containing compound step: a), in said artificial oil, to add weight ratio be 2: 1 the aluminium oxide and the mixture of alumina silicate, and the weight ratio of said mixture and said artificial oil is 1: 100; B), heating contains the artificial oil to 250 ℃ of said mixture, and insulation 1 hour after being cooled to 100 ℃ to 150 ℃ after fully stirring; C), add the sodium carbonate liquor deposition and remove the aluminium ion in the artificial oil.
As optimizing, said adding decolorizing adsorbent is to add atlapulgite according to 5% of said artificial oil weight simultaneously.As another embodiment, the decolorizing adsorbent among the present invention is the mixture that adds silver nitrate, copper sulphate and aluminium chloride according to weight ratio at 0.2: 1.2: 800.Owing to be to adopt silver nitrate, copper sulphate, aluminium chloride adsorbent as the refining system of reduction, adopt natural sedimentation method can be fast, the efficient harmful components of removing in the useless transformer oil, and decolour, its each item index can reach or near new oil standard.The adsorbent consumption is few, and discharging is few, can reduce environmental pollution, helps protecting environment and staff healthy.
The above act person of institute only is the present invention's part embodiment, is not in order to restriction the present invention, causes intention spirit and characteristic according to the present invention, slightly like the modifications person of forming, also should be included within the scope.
