The high-speed electrostatic coalescing oil-water separating device solves the problems that the crude oil dewatering rate is low, drained water contains a large amount of oil and energy consumption is high, expands the space of an electric field, prolongs the crude oil dewatering time in the electric field, effectively improves the dewatering efficiency, saves the operating electricity consumption and reduces the production cost.
Description
Technical field
The utility model relates to the crude oil oily-water seperating equipment, especially a kind of electrostatic coalescence profit high speed separating device.
Background technology
In recent years, along with the most of oil field of China enters the exploitation later stage, the moisture rising of Produced Liquid on the one hand, as Gudao oilfield Produced Liquid maximum water content, up to 98%, offshore oilfield later stage Produced Liquid is moisture can reach 99% for some, on the other hand, exploitation later stage crude oil heaviness, in poor quality trend is more and more obvious, the 1g/cm3 that surpassed as the highest as Crude Oils From Tahe Oilfield density, the density of the super viscous crude of triumph also surpasses 1g/cm3: a large amount of uses of adding oil recovery auxiliary agent in the Deep mining process, cause a lot of oil field mining liquid oil-water emulsions serious, this brings a lot of problems to conventional oily water separation: the operation of (1) electro-dewatering equipment is unstable, due to the moisture height of Produced Liquid, character is poor and emulsification is serious, may be moisture higher after conventional oily water separation, entering electro-dewatering equipment can cause electric current to raise, even tripping operation, affect the safe and stable operation of electro-dewatering equipment, the electric current height also can increase the power consumption of electro-dewatering equipment simultaneously, (2) many, the floor space of equipment progression large, invest highly, because conventional oily water separating equipment efficiency is low, need stage trapping could meet the crude oil water containing requirement, must cause that the equipment number is many, floor space increases, the operation and maintenance expense increase, (3) environmental protection pressure is large, and the crude oil in poor quality adds that the application of oil recovery auxiliary agent causes the emulsification of crude oil Produced Liquid serious, adds that conventional oil-water separation is poor, can cause the draining oil-containing to exceed standard, and brings very large pressure to sewage disposal and environment protection.
The electrostatic coalescence dehydration technique is the most effective isolation technique of water solution of oil, in the oily water separation field, be widely applied, but the conventional electrostatic coalescence technology all adopts the bare metal electrode, although can make low water content crude oil reach better dehydrating effect, can not adapt to the variation demand of current crude oil water content, oil property and mining type.
The patent document that application number is 92208130.1 has been announced a kind of downhole oil-water separation extracting device of oil, and equipment current consumption in service is large, and after high water-cut well liquid is carried out to oily water separation, water content is large, contaminate environment.
In view of the foregoing, existing oily water separation electrostatic coalescence structure needs to improve.
The utility model content
The purpose of this utility model is in order to overcome deficiency of the prior art, and a kind of electrostatic coalescence profit high speed separating device is provided, and effectively improves dewatering efficiency, saves the operation power consumption, reduces production costs.
The utility model to achieve these goals, adopts following technical scheme: a kind of electrostatic coalescence profit high speed separating device is by skid, gun barrel, oil export, high pressure introduction hole, water out, oil inlet distribution, the electrostatic coalescence electrode, fuel-displaced collection tube, the oil transportation water pipe forms; Both sides, skid top correspondence arranges support, and gun barrel is set on support, and the oily water separation pot bottom arranges water out, and the gun barrel upper center arranges oil export, and oil export one side arranges the high pressure introduction hole.
Gun barrel inner bottom part both sides correspondence arranges support, and oil inlet distribution is set on support, and oil inlet distribution is connected setting with the oil transportation water pipe; The gun barrel inner top arranges fuel-displaced collection tube, and fuel-displaced collection tube both sides correspondence arranges the electrostatic coalescence electrode, the setting corresponding to oil export of fuel-displaced collection tube.
Transformer positive and negative electrode circuit should be connected setting through the high pressure introduction hole with two electrostatic coalescence electrode pairs.
The oil inlet distribution surrounding arranges many group liquid distributing holes, and every group of liquid distributing hole is at least 8.
The electrostatic coalescence electrode is that metal electrode board arranges insulation layer formation insulated electro pole plate outward.
The beneficial effects of the utility model are: solve the problem that the dehydrating of crude oil rate is low, the draining oil-containing is many, energy consumption is large, electric field space is expanded, extended crude oil dewatering time in electric field, effectively improve dewatering efficiency, save the operation power consumption, reduce production costs.
The utility model mainly contains following advantage: (1) can adapt to the high-moisture requirement, improves stable equipment operation.Adopt insulated electrode for the electrostatic coalescence process, this clasp Y insulation Y material has higher specific inductivity as fiberglass insulating material, fiber-epoxy insulating material, fluoropolymer insulating coating etc., be coated on surface of metal electrode, can process the high water-content crude oil emulsion, avoid the generation of electric current increase, short circuit between pole plate; (2) realize high efficiency separation, high containing water condition owing to adopting insulating material to be directly used in, therefore can be by conventional three phase separation and electrostatic coalescence technology organic combination, by the electric field reasonable Arrangement, realize the profit high efficiency separation in the oily water separation primary separator, minimizing equipment sum of series equipment number, reduce floor space, reduces operation expense and reduce investment outlay; (3) energy-conserving and environment-protective.For the heavy inferior emulsion, conventional electro-dewatering tank internal emulsification bed thickness, rear draining is containing innage.The utility model can effectively reduce the emulsion layer height, reduces the draining oil-containing, reduces sewage disposal expense and environmental protection pressure.
