Abstract
The present invention discloses an electrostatic oil-cleaning method for removing contaminants in oil by 'pinhole absorption effect' and an electrostatic oil filter using the method, which is suitable for various polluted oil materials with the kinematic viscosity CSC of below 80 in hydraulic oil, lubrication oil, transformer oil, fuel oil, synthetic oil, food oil, etc. The electrostatic oil filter is mainly composed of two sets of parallel polar plates, wherein one group of conductive polar plates is made of double-layer materials with one layer as an insulating layer and the other layer as a polar plate conductive body. Then, pinholes are drilled in the polar plates made of double-layer materials, strong inhomogeneous fields are formed around the pinholes when electricity with the high voltage of between 10KV and 15KV is switched on, and polluted oil and water which pass through the neighborhoods of the pinholes can be totally absorbed into the pinholes when the polluted oil passes.
Description
The present invention relates to a kind of method of removing pollutant in the oil, and employed static oil filter.Be applicable to that the various kinematic viscosity CSC in hydraulic oil, lubricating oil, transformer oil, fuel oil, artificial oil, the food wet goods are lower than 80 oil plant.
In the existing static oil strain technology, mainly be to begin this is studied in 1976 in Japan, and with its product static electricity oil cleaning device application patent.The cardinal principle of the static electricity oil cleaning device of Japan's development is in the parallel plate electrostatic field, puts into the filter paper of " W " type or other shape, at the sharp corner generation inhomogeneous field of paper.Contaminated oil by the time, contamination particle collision filter paper and charged, and produce vibration along the power line direction in inhomogeneous field when having enough momentum, pierces in the hole of paper medium, electrostatic field has reached the effect of blocking contamination particle and adsorption particle.This product in incorporating hydraulic system into after, through tens of hours, can surpass the oil purification of NAS14 level to about the NAS6 level, domestic more existing producers begin imitated this product.But the shortcoming of this static electricity oil cleaning device is: volume is bigger, can not be installed in the walking machine; Water funk, when moisture content surpasses 2000C.C.P.,, easily produce the electric spark puncture short because the paper medium is arranged.
The object of the present invention is to provide a kind of " aperture adsorption effect " electrostatic oil cleaner method and designed a kind of new static oil filter in this way, it can remove all contaminations that comprises moisture content.Accomplish that volume is little, safety, reliable not only can be used in general hydraulic system, and can be installed in the hydraulic system of walking machine.
" aperture adsorption effect " of the present invention electrostatic oil cleaner method is to utilize collision electrode method, makes the well cuts particle charged behind the collision pole plate, flows into inhomogeneous field with oil then, and charged particle is inhaled into aperture under the electric field force effect.According to above-mentioned absorption principle, carried out some preliminary experiments: voltage is 7.5KV, and polar plate spacing is 5mm, and the contaminated oil flow is 2l/min, and processing volume is that 25l(is 25 * 10
-3m
3), the time is 8 hours, gets rid of some disturbing factors, obtains following data:
| Granulometric range | The number of crude oil (among every 100ml) | Number after the processing (among every 100ml) |
| 5～15μ | 940640 | 16853 |
| 15～25μ | 168467 | 15273 |
| 25～50μ | 64923 | 4353 |
| 50～100μ | 10123 | 187 |
| 100μ | 1077 | 0 |
Water content in the contaminated oil surpasses 10 * 2000CCP, but after treatment, drops to below the 2000CCP.Obtained very desirable effect.
In view of the above, the invention provides " aperture adsorption effect " electrostatic oil cleaner method: in the parallel plate electrode electric field, wherein a conductive plate changes into double layer material, and one side is an insulating barrier, and another side is the pole plate electric conductor, on this pole plate, bore 1mm～3mm aperture then, pitch of holes is 30mm～60mm, connects 10KV～15KV high-tension electricity, promptly forms very strong inhomogeneous field around aperture, contaminated oil is when the pole plate, and near all contamination particle and moisture content aperture all can be inhaled in the aperture and goes.
According to " aperture adsorption effect " electrostatic oil cleaner method, the present invention also provides a kind of novel static oil filter.Below in conjunction with accompanying drawing this being done one describes in detail.
Fig. 1 is a front view.
Fig. 2 is a vertical view.
With reference to Fig. 1, the static oil filter mainly is made up of top crown (1), collets (2), adsorption plate (3), collection box (4), insulation crust (5), electrical equipment box (6), oiler (7), oil-out (8).The center of top crown (1), having several radiuses is 0.1mm～1mm aperture, the material requirements of top crown has certain intensity, and is corrosion-resistant, electric conductivity good metal plate or alloy sheets.Adsorption plate (3) is a double layer material, and the upper strata is an insulating materials, and lower floor is corrosion resistant conductive layer, and has a plurality of apertures, is evenly distributed on the adsorption plate, and the aperture is 0.5mm～4mm, and aperture centre-to-centre spacing is 2mm～6mm.The back of adsorption plate (3) is placed with collects box (4), and the aperture of two symmetries is arranged on the box, plays the oil effect, and the height of box is 1mm～5mm, is conductive material.Adsorption plate (3) and mistake oil box (4) are equipped with the oil-through hole of two symmetries on same position, the aperture is 2mm～6mm.The height of collets (2) is 5mm～20mm.High-tension electricity is 5KV～20KV.When contaminated oil enters the static oil filter by fuel feed hole, owing to fed high voltage, formed high-voltage dc between pole plate at parallel plate electrode, because collision electrode method principle, the impurity particle in the contaminated oil is promptly charged, is inhaled into to collect in the box.After between several groups of parallel plate electrodes of contaminated oil process, be filtered into pure oil and flow out oil outlet.The contamination particle of collecting box can take out and remove after outage.Handling the pollution oil mass is 2.5 * 10
-3m
3/ min～6 * 10
-3m
3/ min.
This static oil filter structure is simple, easy to operate, absolute oil efficient height, and the moisture content in the contaminated oil can be eliminated equally, even under very moist mine, also can use, is desirable oil filtering unit.
