Abstract
The utility model provides an efficient and energy-saving electric desalting composite polar plate device. The device comprises a plate body; a non-conductive material layer with temperature resistance, pressure resistance and corrosion resistance is arranged on the outer surface of the plate body; and an isolating layer is formed at the periphery of the polar plate, so as to block the current path between the polar plate and oil. However, lines of field intensity can penetrate the isolating layer to aggregate moisture content in the oil, so as to achieve the purposes of desalination and dehydration. The utility model has the advantages that the whole device saves electrical energy by more than 60 percent, the electric spark hazards are reduced, the capacity of oil treatment is enhanced, and both the security and reliability of equipment are improved.
Description
Technical field
The utility model relates to a kind of compound polar plate of electric desalting/water trap, particularly is used for desalination/water trap is carried out in fields such as refinery, oil recovery factory to oil product compound polar plate.
Background technology
Now recover the oil, oil refining and power plant etc. are for removing salt or the moisture that contains in the various oil plants, adopt direct current usually or exchange electrostatic field desalination/water trap.Placement level or vertical metal pole plate in oil tank apply voltage and form electrostatic field on pole plate.Be in water molecules in the oil plant in the electrostatic field under the electrostatic attraction effect mutually polymerization become big water body and drop to tank bottom and discharge through pump valve or natural gravity in action of gravity, reach the purpose of desalination/anhydrate.Pole plate is a core component of desalination/water trap.The shortcoming of prior art is because pole plate is made by the bare metal material, owing to be applied with the above high-voltage of 10KV on the pole plate, moisture in the oil plant and impurity form resistance and produce electric current between pole plate, under the Jiao Er effect, a large amount of electric energy will become useless heat and be wasted; Electric current also can generate comparatively complicated material attack metal pole plate and influence the oil plant quality by ionogen generation electrolytic action; To moisture in the oil plant and impurity discharge generation electrical spark, not only the additive decrementation electric energy more can cause damage to equipment easily.In addition, because of electric current strengthens, supply transformer and circuit internal resistance produce pressure drop, make voltage decline between pole plate, and intensity of field reduces, the desalination/deleterious of anhydrating.When the oil plant water ratio surpasses certain percentage, the effect that is short-circuited between pole plate, system can't power on and put into operation.Because power consumption is very big, and supporting power supply facilities, pole plate and high pressure introducing device etc. are had very high requirement, failure rate height in the practical application also brings out industrial accident easily, and safety performance is relatively poor.
The utility model content
Technical problem to be solved in the utility model provides that a kind of energy consumption is low, desalination/compound polar plate that is used for oil plant desalination/water trap effective, that safety performance is high and simple in structure anhydrates.
In order to solve the problems of the technologies described above the utility model, a kind of energy-efficient electric desalting compound polar plate device, comprise plate body, wherein, the outside surface of described plate body is provided with the non-conducting material layer, perhaps is configured as plate shape with the electric wire or the cable that have the non-conducting material appearance.
Above-mentioned a kind of energy-efficient electric desalting compound polar plate device, wherein, described metal plate material surface is provided with non-conducting material, its material behavior: heatproof more than 130 ℃, withstand voltage 20KV are above, the material of acid and alkali-resistance.
The utility model can be realized following beneficial effect:
1, because described plate body outside surface is provided with the non-conductive layer of heat resisting and pressure resisting corrosion resistant, form the electrical isolation layer in pole plate metal periphery, during use, can block the current path between pole plate and the oil plant fully, there is electric current to flow through in the resistance of avoiding moisture in the oil plant and impurity to form, and lines of field intensity can pass sealing coat to the generation of the moisture in oil plant congregation, thereby reach the purpose of desalination/anhydrate, reduced energy consumption, whole desalination/water trap saves energy is surpassed more than 60%, saved resource greatly;
2, the utility model, being applied to voltage on the pole plate can not be subjected to the influence of oil plant water ratio and reduce, also can work under the very poor situation of oil plant quality, more can not cause because water content exceeds standard to shut down to stop production, reliability improves, the desalination/effect of anhydrating surpasses conventional apparatus;
3, because the reduction of power consumption, electric current descends, machinery and electric property to power supply distribution facility, pole plate and high pressure introducing device require to reduce greatly, can reduce electrode thickness, weight reduction can be dwindled polar plate spacing on the technology, obtains can reduce voltage between pole plate under the situation of identical field intensity density, form benign cycle, thereby reduced production cost, improved reliability.
4, because the setting of described non-conductive sealing coat can prevent the generation of electrochemical etching and electrical spark harm, prolong the work-ing life of pole plate, thereby further improved the security of device,

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in the figure, in order to solve the problems of the technologies described above, a kind of energy-efficient electric desalting compound polar plate device of the utility model, comprise plate body 1, plate body 1 is formed by first steel (also available metal pipe or with the electric wire or the cable that have heatproof, withstand voltage and corrosion resistant appearance) moulding, outside surface (comprising end face) is provided with non-conducting material layer 2, and shape can be that template, grid etc. are installed and the related process requirement to adapt in the electric desalting tank body.
The outside surface of described plate body 1 is provided with non-conducting material layer 2, is meant appearance coating or installation non-conducting material layer at the metallic substance of forming plate body.The mounting means of non-conducting material layer 2 is unrestricted, can be coating, tight fixing or other method etc., and purpose is to allow the outside surface of whole pole plate that one deck compact isolating layer is arranged, and makes the plate body interior metal directly not contact oil plant and forms electrical isolation.The material behavior of non-conducting material layer 2 requires tolerable temperature more than 130 degrees centigrade, tolerating high voltage more than 20 kilovolts, acid-alkali-corrosive-resisting.Recommend to use tetrafluoroethylene.
