Abstract
The regeneration of degraded oil for electric power equipment adopts flyash and active white clay as regenerating material. Flyash as one waste from power plant has the lattice skeleton similar to that of available regenerating material and can eliminate acid matter and colloid and other degraded matters from electric power oil through adsorption. The present invention has high environment utility.
Description
The present invention relates to the material of degradation treatment, particularly a kind of degraded oil for electric power equipment.
Oil for electric power produces very big harm to power equipment when in use deterioration is rotten.Transformer oil, turbine oil and hydraulic pressure fire resistant oil are subjected to factor affecting such as air, temperature, electric field when carrying out in power equipment, oil ageing is rotten.When transformer oil, turbine oil and the aged deterioration of hydraulic pressure fire resistant oil, produce alcohol, aldehyde, ketone, further generate acidic substance, the further oxidation of acidic substance, polymerization generate colloidal pitch shape thing greasy filth throw out, and these greasy filth have very strong corrodibility, return the insulating property that reduce transformer oil and make the insulating material embrittlement of oil-filled electric installations such as transformer, mutual inductor rotten, produce equipment failure, the generator metal is produced corrosion, influence the normal operation of generator.Anti-burner is pressed with under the effect of water at the Gao Wengao of generator, phosphoric acid fat returns hydrolysis gradually, generate acid phosphatase fat and phenol, and further condensation generates low molecular acid and polymer ageing products, shortened oily work-ing life, also make the generator velocity control system produce faults such as the burn into bite is malfunctioning, the normal operation that jeopardizes generator.The material that is generally used for the electric power waste oil regeneration at present is as home-made, 801 and 988 serial sorbent materials as Lanzhou Oil Refinery, the WDX series sorbent material of Hubei filial piety Sheng power supply administration, the efficient absorption powder sorbent material of Shenyang Transformer Factory, also useful diatomite filter core carry out filter regeneration electric power waste oil.Present price is very expensive, and production cost improves, and the latter is to the DeGrain of the too high degraded oil for electric power equipment of acid number.
The object of the present invention is to provide a kind of favorable regeneration effect, degraded oil for electric power equipment renovation process that production cost is low.
Task of the present invention realizes by this way: this electric power waste oil regeneration material is flyash and atlapulgite.Because fine coal has the lattice framework similar with applying to the oil for electric power reproducing adsorbent at present.When waste oil flow through flyash, flyash was promptly inhaled the deterioration product in the waste oil and is bowed, and deterioration materials such as acidic substance and colloid are removed.In order to accelerate settling velocity, in flyash, add atlapulgite.
Adopt the detailed process of present method regenerating degraded oil for electric power equipment as follows:
At first, flyash and atlapulgite were dried 2 hours under the temperature of 110-130 degree, sealing is preserved before using, and proportioning is to be equivalent to oil weigh 20% flyash and add 3% atlapulgite during regeneration deterioration oil, pack into the filter core of adsorption tanks of flyash that proportioning is good and oiliness carclazyte.With pump sump tank is advanced oil tank, pressure by in-line pump and oil filter oil pump circulates waste oil, when non-oil is flowed through adsorption tanks, sorbent material fine coal in the adsorption tanks and atlapulgite can adsorb deterioration product in the waste oil, can remove acid position and the big sense of colloid deterioration material.
Compared with prior art, the present invention has following advantage:
(1), can be with the acidic substance of degraded oil for electric power equipment and gum-treated to meeting the fresh oil standard substantially.
(2), adopt technical scheme of the present invention, only need utilize fly ash in electric power plant, cost is low, and the protection environment, is a kind of economically viable method.
(3) equipment and technology are simple, processing ease.
Embodiment 1
Guangzhou Zhujiang River Utilities Electric Co., Ltd. adopts this clearly demarcated technology that oil for electric power is regenerated, and every index is as follows before the regeneration:
| Project | 1# unit EH system degradation oil |
| Outward appearance | Transparent |
| Color | Reddish brown |
| Kinematic viscosity (mm/s) | ????37.81 |
| The meat point (degree centigrade) | ????248 |
| Acid number (mgKOH/g) | ????0.75 |
| Granularity | Greater than 6 grades |
Adopted flyash to replace traditional sorbent material, increased the secondary filter net, regeneration and essence are filtered in one, the regeneration condition of carrying out is: temperature 31 degree, 2 kilograms of pressure, 20 liters/minute of flows, regenerate and after 44 hours recovered oil is carried out the sampling analysis chemical examination, acid number has reduced 0.1mgKOH/g, and the particle contamination degree is from dropping to 5 grades greater than 6 grades, and effect is fairly obvious.In regenerative process, do not find the flyash seepage.Every index after regeneration is as follows:
| Project | 1# unit EH system degradation oil |
| Outward appearance | Transparent |
| Color | Brown |
| Kinematic viscosity (mm/s) | ????37.92 |
| The meat point (degree centigrade) | ????250 |
| Acid number (mgKOH/g) | ????0.63 |
| Granularity | 5 grades |
Claims (2)
- The method of 1 one kinds of regenerating degraded oil for electric power equipment, the oil for electric power that it is characterized in that making deterioration is by a kind of filtering material of being made up of flyash and atlapulgite, and flyash and atlapulgite must be dried 2 hours under the temperature of 110-130 degree before use.Must sealing preserve before using.
- 2 methods according to claims 1 described regenerating degraded oil for electric power equipment, when it is characterized in that regenerating degraded oil for electric power equipment proportioning for corresponding to recovered oil 20% flyash, 3% atlapulgite.
