Embodiment 3
Adsorbent is provided with adsorption tanks group 4 described in embodiment 1, the adsorbent is including in parts by weight with the following group
Point：Mass percent concentration is 17% 25 parts of hydrochloric acid solution, and mass percent concentration is 24 parts of 9% metabisulfite solution, quality
Percent concentration is 8% 25 parts of sodium silicate solution, and concentration is 19% 1.32 parts of ammoniacal liquor.Above-mentioned solution is carried out after mixing
It is aging, drying is toasted, it is made adsorbent finished product.The aging temperature is 85 DEG C, ageing time 7 hours.The drying baking temperature
After 110 DEG C of degree is carried out after baking is dried 4 hours with phosphoric acid dip, clean with water, place into baking, 135 DEG C of baking temperature is toasted
Obtain adsorbent finished product within 23 hours.Adsorbent finished product average pore size reaches 10~50nm.The specific surface of adsorbent is in 300-
500m2/g。
Insulating oil is deteriorated and contaminated impurity is generally the material of macromolecular and big particle diameter, such as by atoms such as nitrogen, oxygen, sulphur
The compound that composition is commonly referred to colloid is combined with unsaturated hydrocarbons, particle line footpath is in 1~100nm metallic dusts and suspension carbon granule line
10~10000nm of footpath, and the filter degree of general industry filter paper is 20000~30000nm at present, most accurate its filter degree of filter part is about
It is 500nm, therefore, above-mentioned particle matter need to be adsorbed with adsorbent and removed.Due to the present embodiment adsorbent aperture ratio silochrom
Aperture it is also big, be especially beneficial the interior diffusion of big line footpath impurity in oil, it is ensured that suction-operated occurs in bore area, makes suction
Attached potential gives full play to.
Comparison example：Metal particle (copper, iron) content is 125 μ g/g oil, oil in 40 tons of oil of power supply administration 220kv main transformers
Dielectric loss 1.93, this innings carries out adsorption treatment using embodiment adsorbent 2%, and after 96 hours, copper, iron content are down to 0 in oil
137 μ g/g oil, oily dielectric loss t0.08.
Adsorption capacity characterizes the capacity of water of adsorbent purification oil.Can generally be adsorbed equivalent to how many with 1 gram of adsorbent
The acidic materials of milligram potassium hydroxide represent, unit mgKOH/g.
The present embodiment adsorbent adsorption capacity of table 1 is contrasted
From data above, the adsorption capacity of 1% carclazyte of the present embodiment adsorbent equivalent to 10%.Therefore have
Feed intake few, the characteristics of efficiency high.
Embodiment 4
The desulfurizing agent of use is additionally provided with the adsorption tanks group 4, the desulfurizing agent preparation method is：With acid dissolving konjaku Portugal
Glycan obtains the konjaku dextran solution of 1.6g/L, while stirring to ammoniacal liquor is added dropwise in konjaku dextran solution to there is insoluble matter to start
During precipitation, the copper sulphate of 6.6g/L is added, be stirred continuously after copper sulphate is all dissolved, 40 times of konjaku glucan quality of addition
Activated carbon, after stirring 2 hours, filtering, drying is dried, after absorption ammonia saturation, at 600 DEG C, in ammonia and nitrogen mixture atmosphere
Product is obtained after reduction activation.The concentration of the above ammoniacal liquor is 8g/100mL；The concentration of the acetic acid is 1.4g/100mL.
Take certain nuclear power station and obtain operation oil (total sulfur content 2339.26mg/l) that factory becomes, oil is tried after taking back laboratory
Test, various adsorbents be separately added into by the 10% of oily weight, adsorption conditionses be respectively 60 DEG C/48h, 60 DEG C/72h, 60 DEG C/96h；So
Five kinds of oil samples are filtrated to get to the oil sample after adsorption treatment afterwards, its total sulfur content, contrast effect is measured：
The present embodiment desulfurizing agent desulfurized effect of table 2 is contrasted
Tested more than, the data of the sulfur content measured more than can be seen that on the present embodiment desulfurized effect substantially
Better than unmodified activated carbon.
The data of the sulfur-bearing of measurement can be seen that the lower absorption desulfurization effect of temperature more high viscosity that desulfurization is adsorbed more than
Fruit is better, it is contemplated that lowering the influence of transformer oil ageing as far as possible, the running temperature in adsorption tanks of desulfuration adsorbent sets
It is set to 65 DEG C~70 DEG C.
The active sulfur content of oil sample substantially changes after adsorption treatment, is entered by ASTMD 1275-2003 (B methods)
The sulfur corrosion of row insulating oil is tested, and the corrosive impurity in sample is qualitatively detected according to copper sheet surface state.The corrosion journey of copper sheet
Spend dramatically different (Fig. 3)：
ASTMD 1275-2003 (B methods) are copper sheet and sample under rated condition (degassing, heat 48 hour at 150 DEG C)
(transformer oil) is contacted, and the active sulfur compound in sample can cause copper sheet to go bad, and qualitatively be detected according to copper sheet surface state
Corrosive impurity in sample.

In 85 DEG C, 12 hours time, per water is changed every other hour once, until occurring without greasy dirt on the water surface, the volume ratio of water and adsorbent
It is 100:1.The adsorbent that taking-up was boiled is put into 100 DEG C of oven for drying, is then placed in calcination 5 hours in 550 degree of Muffle furnaces, cools down
It is stand-by；
D is that poor oil of learning from else's experience soaks the adsorbent of embodiment 3 of 48 hours and is put into regenerative agent, temperature control at 60-65 DEG C,
The volume ratio of detergent and adsorbent is 100:1, wash time 1 hour, washing times 2 times, then with (80-85 DEG C) immersion of water
Rinse 3 times, each half an hour time.Adsorbent after treatment is then placed in being dried in 100 degree of baking oven, is then placed in 450 degree
Calcination 4 hours in Muffle furnace, cool down stand-by；
What D-1 correspondences were added is regenerative agent 1, and what D-2 correspondences were added is regenerative agent 2, and what D-3 correspondences were added is regenerative agent 3,
What D-3 correspondences were added is regenerative agent 4.
The drop dielectric loss that different regeneration processing modes are used for poor oil is processed, the oily dielectric loss for measuring (uses AI-6000 dielectric loss
Instrument, cleaning lubricating cup does empty cup dielectric loss) it is as follows：
The drop dielectric loss that the different regeneration processing modes of table 3 are used for poor oil is processed
| Numbering | A | B | C | D-1 | D-2 | D-3 | D-4 |
| Dielectric loss value (%) | 19.58 | 10.109 | 8.378 | 7.140 | 6.728 | 6.125 | 5.231 |
Find out from result of the test, by the adsorbent of regenerative agent regeneration treatment, the ability of its drop dielectric loss is omited than novel sorbents
It is high, it may be possible to which that abundant washing and secondary calcination in due to regenerative process cause the skeleton structure of adsorbent more to expand, specific surface
Product is bigger.Relative to water-boiling method, the regeneration treatment time of regenerative agent shortens about 2/3rds, required heating-up temperature reduction
100 DEG C, only have a small amount of black smoke to emerge in processing procedure, it is basic without dirt after conduit imports discarded de-oiling detergent
The discharge of metachromia gas.
