Description
Technical field
The invention belongs to electric desalting and electro-dewatering apparatus technical field in crude oil upgrading process, particularly in complete electric desalting electro-dewatering apparatus, high voltage electric is introduced key part---the high voltage electric leading-in rod in electric field.
Background technology
Complicated along with crude oil quality, also more and more serious to the extent of corrosion of equipment in preprocessing process.In order to alleviate the corrosion to equipment, in the work-ing life of extending catalyst, crude oil desalting is that petrochemical industry and oil refining enterprise carry out pretreated indispensable measure to crude oil.Crude oil through once, normal containing the impurity such as sulphur, nitrogen in the various oil fuel that obtain after secondary processing, these impurity effects quality of oil product, can cause serious corrosion to equipment in deep processing and transportation.Enterprise of petrochemical refining often adopts direct current purification apparatus to apply acid-alkali treatment under high-voltage electric field and is refined by oil product, is that oil product reaches defined technical indicator.In purification apparatus, we utilize high voltage electrode bar to be introduced by high voltage electric in electric desalting, electrofining tank.Introduce the voltage of supply of tank generally all at about 22KV, high voltage electric leading-in rod runs so will ensure that long period safety is normal, it must possess three conditions simultaneously: one is, it must have high-insulativity, do not puncture under the condition of test voltage 100,000 volts, and ensure not puncture in equipment long-term operation process, otherwise it will make equipment not send electricity, and serious also can cause fire failure; Two are, must have good high-temperature stability, can long period work at the temperature of about 140 DEG C, and in high voltage electric leading-in rod surface adsorption, charged particle is creepage causes shelf depreciation, also can not burn and melt when temperature reaches more than 1000 DEG C; Three are, high voltage electric leading-in rod self structure, and with the installation of desalter, treatment tank tank body, all must ensure No leakage, and in equipment long-term operation process, under comparatively high temps and pressure state, crude oil or processed oil non-leakage.For many years, form the high voltage electric leading-in rod of various structure formation with much materials processing, owing to can not meet above-mentioned three conditions simultaneously, cause that high voltage electric leading-in rod punctures, seepage or burn is melted, and is that equipment can not normally run.This kind of situation, in electric desalting, electrorefining equipment failure, proportion has about 70%.In the equipment use process of decades, people are to the making materials and structures form of high voltage electric leading-in rod, and carried out a large amount of explorations and improvement, some drawbacks is overcome, and work-ing life is also increased.But, puncture, the phenomenon such as seepage still happens occasionally, particularly in direct current purification apparatus runs, because high voltage electric leading-in rod produces electrostatic on the surface, and the charged particle adsorbed in a certain amount of medium, high voltage electric leading-in rod is caused creepage, and in the electric discharge of high voltage electric leading-in rod upper metallization material parts place, produce very high temperature.
Facts have proved, traditional electrode bar effect in electric desalting apparatus is good, but in electrofining tank because of clean petroleum product in add alkali, electric conductivity is caused to improve, have employed high voltage in addition, easily produce creepage, flashover on electrode bar surface, burn out electrode bar, the normal operation of producing can not be ensured.In addition, because the cable in electrode bar easily rotates, in transport, installation process
In very easily produce cable copper core break to fall and loose contact.Therefore electrode bar requires high temperature resistant, high insulating property in refining, desalination operational process, in use not creepage, not flashover, do not puncture.
Through retrieval, disclose two kinds of electrode leading-in rods at present, be respectively the high voltage electrode bar of application number 95239810.9 and the high-temp. resistance compound high-voltage electric leading bar of application number 03259374.0, above-mentionedly substantially to meet the demands in normal course of operation, but when meeting that oil quality is very poor, foreign matter content is many, saltiness is high on occasion, lower end due to two kinds of electrode bars is all the structure with seamed edge, the electrode bar of this structure produces arc erosion in equipment discharges operation for a long time, thus shortens the life-span of electrode leading-in rod.In addition two kinds of electrode leading-in rods are all installed by oil tank adapter, electrode bar connection seat part is arranged in adapter, adapter is communicated with oil tank, therefore need when overhauling transformer and changing connecting hose that oil is moved back in the pressure release of oil tank oil can operate, extremely inconvenient, seriously have impact on the normal production of enterprise.
Summary of the invention
Object of the present invention exactly will for the long-term electric discharge in high pressure vessel of existing electrode bar run produce arc erosion cause work-ing life long, install inconvenient, easily the problem such as leakage carries out texture improvement.For the problems referred to above, now provide a kind of self-sealing packing formula high voltage electric leading-in rod, this high voltage electric leading-in rod is safe and reliable, good insulation preformance, does not puncture, not creepage, do not reveal, long service life and easy for installation, prevent high pressure vessel from causing because of sealing leak losing efficacy in operational process.
Technical scheme of the present invention is:
A kind of self-sealing packing formula high voltage electric leading-in rod, comprises excellent cap, barred body and connection seat, arranges plug screw, cable, high pressure resistant heat-shrinkable tube, liner and neck bush in described excellent cap, barred body and connection seat.This structure also comprises self-tightening type connection seat, with joint flange, sealing member and joint bolt that connection seat is supporting, and nut.Plug screw, liner are connected by taper thread with barred body, liner is inserted with neck bush, high pressure resistant heat-shrinkable tube is placed in neck bush, copper core is had in cable, can high voltage electric be incorporated in tank by copper core, the high pressure resistant heat-shrinkable tube of outside coated one deck, the contact with moisture cable of effective entry deterrence high voltage electric leading-in rod inside, prevents from burning out high voltage electric leading-in rod.The part that cable sheath is peelled off can be protected banding by high pressure resistant heat-shrinkable tube, prevents cable polytetrafluoroethylene membrane loose.
There is umbrella-shaped structure described barred body lower end, is structure as a whole with barred body, effectively stops the moisture being gathered in high voltage electric leading-in rod surface to be connected taper thread by barred body with excellent cap and flows to high voltage electric leading-in rod inside, prevent from burning out high voltage electric leading-in rod.
