Abstract
The utility model relates to a high-speed electric desalinating and dewatering device. The device can lead crude oil to be ejected from a lower layer electric field which is composed of electrode plates (3), (4) and a position at the lower part of the electrode plate (4) at the bottom layer approaching to the electrode plate. The utility model uses a weak electric field formed from the electrode plate (4) at the bottom layer and an oil-water boundary to remove most of large water drops to reduce the electric conductivity of the crude oil. Then the utility model enters a high voltage electric field for removing small water drops. The technical indexes that after desalination and dewatering, 0.2% water is in the crude oil, and less than 3 mg/L salt is in the crude oil can be obtained. The energy consumption is only one half of the energy consumption of the similar device. The utility model better solves the technical problem that the crude oil is directly ejected into the high voltage electric field by the similar device, which can easily cause a short circuit or breakdown.
Description
The utility model belongs to oil field electro-dewatering, refinery crude oil electric desalting field, particularly a kind of petroleum chemical industry crude oil electric desalting equipment that is used for.
External high speed electric desalting equipment arranges that in tank body three layers of horizontal electrode plate form two alternating-electric fields at present, and the emulsion of crude oil and water directly is sprayed onto two alternating-electric fields from horizontal oil-feed divider.But this oil-feed mode of high speed electric desalting equipment exists weak point, because two electric fields all are high-voltage electric fields, the drops of water fall down of building up in the electric field of upper strata is in lower floor's electric field, self also has a large amount of drops of water fall down lower floor's electric field, more like this water droplet makes the high pool of lower floor's electric field electric conductivity increase, and electric field short circuit or electric field breakdown take place easily.
The purpose of this utility model provides a kind ofly to be guaranteed under the situation of amount of finish, can avoid taking place electric field short circuit or electric field breakdown, guarantees the high speed electric desalting electro-dewatering equipment of the normal smooth running of equipment.
A kind of high speed electric desalting electro-dewatering equipment described in the utility model is made up of high speed electric desalting tank body, three layers of horizontal electrode plate, power source special and horizontal oil-feed divider; It is characterized in that: described horizontal oil-feed divider shower nozzle is arranged in the position of the close battery lead plate of bottom electric field and orlop battery lead plate bottom of two lower electrode plates compositions; Water solution of oil evenly is sprayed onto the weak electric field of described high-voltage electric field and orlop battery lead plate and the formation of profit circle position from horizontal oil-feed divider.
Aforesaid a kind of high speed electric desalting electro-dewatering equipment is characterized in that: described three layers of pole plate can be connected with the alternating-current output terminal with the DC output end of power supply respectively.
The utlity model has following effect: the weak electric field that utilizes orlop pole plate and profit circle position to form removes the big water droplet of major part, reduce the specific conductivity of crude oil, and then enter in the high electric field, fine liquid particles is removed, can reach and take off back crude oil water containing 0.2%, saliferous is less than the technical indicator of 3mg/L, and energy consumption only is 1/2nd of a same category of device.
The drawing explanation:
Fig. 1 is a structural representation of the present utility model.
Power supply of the present utility model can adopt high speed electric desalting electro-dewatering device-specific power supply, while output AC electricity and positive and negative half-wave high voltage direct current, design triple electrode plate, form two high-voltage electric fields, orlop electrode and profit circle position form weak electric field, crude oil from weak electric field and below spray a high-voltage electric field, weak electric field can remove most water droplet, the crude oil specific conductivity that has guaranteed to enter top high-voltage electric field is not too high, and electric field short circuit or electric field breakdown can not take place.Below in conjunction with accompanying drawing an embodiment is described as follows: high speed electric desalting power source special (1) is input to pole plate (2) with direct current and alternating-current, (3), (4) on, pole plate (2), (3), with (3), (4) form high-voltage electric field between, charged pole plate (4) forms weak electric field with profit circle position, water solution of oil evenly is sprayed onto by (3) from horizontal oil-feed divider (5), (4) form high-voltage electric field and pole plate (4) and form weak electric field with profit circle position, the drops of water fall down that settles down in the high-voltage electric field is in weak electric field, form big water droplet with settled water droplet in the weak electric field, though the medium electric conductivity in the weak electric field is higher at this moment, but because the voltage in the weak electric field is less, arc-over can not take place also can not be short-circuited or breakdown accident, the normal operation of assurance equipment, power consumption also reduces greatly simultaneously, running cost descends, and safe reliability improves.
