Description
Technical field
The invention belongs to solid sorbent compositions or filtration adjuvant compositions field, specifically, it is related to a kind of transformation
Device deterioration oil adsorbent and preparation method thereof.
Background technology
Transformer oil in the running of transformer, due to the high temperature in foreign substance pollution or running, electromagnetic field,
Metal catalytic etc. influences, and can be oxidized, and then well cuts increase, oil colours muddy, eventually become the abandoned oil of deterioration.Existing skill
Relatively common processing method is to use H in art2SO4- carclazyte method, Acid-Base-carclazyte method are adsorbed to transformer oil, but mainly
There is following defect：The aqueous chemical material such as acid, alkali is used in processing procedure, potential safety is there is for operator hidden
Suffer from, and some acid sludges and alkaline residue can be produced, it is impossible to processing and utilization, larger pressure is caused to environment.
The content of the invention
To solve the above problems, the present invention provides a kind of comparatively safe, advantages of good adsorption effect transformer deterioration oil absorption
Agent and preparation method thereof.
Transformer of the present invention deteriorates oil adsorbent, includes the active princlple of following parts by weight：Aluminum oxide 30-40
Part, 20-40 parts of sodium metasilicate, 20-30 parts of aluminium chloride.
It is preferred that, the adsorbent includes the active principle of following parts by weight：30~35 parts of aluminum oxide, sodium metasilicate 30~35
Part, 25~30 parts of aluminium chloride.
Further, it is a further object to provide the preparation method that described transformer deteriorates oil adsorbent,
Comprise the following steps：
(1) sulfuric acid is added to be well mixed in aluminum oxide, sodium metasilicate, aluminium chloride；The mass fraction of sulfuric acid used is 25-40%；
(2) particle that particle diameter is 2-3mm is made in gained mixture in (1) with forming machine；
(3) particle obtained by step (2) is placed in baking oven in being baked and banked up with earth at 70 DEG C 2 hours；Then quickly temperature is increased to
700 DEG C, drying produces dry particle thing finished product for 1 hour.
Adsorbent of the present invention, can both be made particulate matter finished product, finished product is directly placed into transformer oil and passed through
The natural sedimentation of particulate matter, and then the impurity such as the oxidation material in transformer oil are taken away, it can also be made by the following method
Adsorption filter board：Adsorption filter board includes being placed in the filter plate I on upper strata and is placed in the filter plate II of lower floor；The aperture of filter plate I is 200-
250um, the aperture of filter plate II is 160-190um；The top of filter plate II is uniform to place obtained particulate matter finished product, particle in step (3)
Filter paper or filter cloth are provided with above thing finished product.Meanwhile, for increase filter effect, the top of filter plate I, which can also be placed in step (3), to be made
Particulate matter finished product, or multilayer and the identical filter plate of filter plate II are set.
When the function of filtering absorption is realized using filter plate, the aperture of upper strata filter plate is larger, can be by transformer oil
Insoluble matter is stayed on filter plate I, and then can mitigate the filtering adsorptive pressure of filter plate II, then can using the absorption of multilayer filter plates
Preferably the impurity in absorption transformer oil, obtains the more preferable oil strain excessively of quality.
Compared with prior art, the beneficial effects of the invention are as follows：
(1) adsorbent of the present invention is inorganic composition, nontoxic, nonflammable, will not be triggered during waste oil disposal
Fire etc. dangerous；And adsorbent used and preparation method thereof cost is relatively low, without environmental pollution；
(2) absorbent particles prepared by the present invention, with larger specific surface area, aluminium chloride in itself can be as refined
Agent, while aluminum oxide and sodium metasilicate powder can also be made to be attached to its surface as carrier forms particulate matter, in the presence of carrier,
The larger particulate matter of specific surface area can be formed, and then adsorption effect can be improved；
(3) aluminum oxide, the rigid-skeleton containing hydroxide Crystallization can carry out decolouring suction to transformer oil
It is attached, transformer oil is recovered primary colors；The three-dimensional framework shape structural compounds that sodium metasilicate is made up of silica and aluminum-oxygen tetrahedron, energy
Impurity enough in absorption transformer oil, and the compound specific surface area of skeleton structure is big, adsorption effect is more preferably.
