The utility model is characterized in that: an axis of the ultrasonic action area follows the same direction of the flowing crude on a pipeline before the crude oil flows into the electrostatic desalting pot so that the ultrasonic wave can function on the crude oil for long time; the ultrasonic wave action area is pipeline-structured, which is made up through the combination of an vertebral pipe area and a straight pipe area by a flange; an ultrasonic probe is arranged at an end of the ultrasonic wave action area; the other end of the ultrasonic wave action area is the vertebral pipe area; reflecting wave made by reflecting surface of the ultrasonic wave can not emulsify the crude oil through superposition or focus and then an uniform ultrasonic wave action area is provided.
Description
Technical field
The utility model relates to a kind of device that is used for crude oil desalting and dehydration.
Background technology
Crude oil desalting is the important treatment process of oil field and oil plant with dehydration, the quality of desalination degree, directly have influence on the follow up device of crude oil processing, the oil plant that particularly needs deep processing, behind the crude oil desalting, require salt content≤3mg/l, water content≤0.3%, and the oil plant that can reach this requirement at present is seldom.Present crude oil desalting both domestic and external and dewatering mainly contain heating, the electric field that adds high pressure, add demulsifier and their compound action, but along with the crude oil quality variation, and the effect that these methods are handled crude oil can't satisfy the needs of process units.Therefore, the desalination that electric field combines with ultrasonic wave and the device of dehydration occur, be used for satisfying the requirement of producing.On November 4th, 1998, disclosed notification number was that the CN2296230Y utility model patent is made up of electro-desalting device, ultrasonic wave active region, ultrasonic probe etc.Its ultrasonic probe installation direction is vertical with the active region axis direction, makes that the direction of ultrasonic wave effect is vertical with the flow direction of crude oil.With regard to single ultrasonic probe, crude oil is short in the time of staying of ultrasonic wave active region, ultrasonic wave is because the focusing of hyperacoustic back wave of the intrados of pipe is easy to generate the local excessive sound intensity, make that ultrasonic wave active region ultrasonic intensity is inhomogeneous, cause the emulsification of crude oil easily and make and take off that oil content improves in the water of back, therefore have problem and the shortcoming of some.
Summary of the invention
Technical problem to be solved in the utility model is at electric desalting apparatus, and uniform ultrasonic wave active region is set, and the prolongation ultrasonic wave forms ultrasonic wave-electric field associating desalter to the action time of crude oil, improves the effect of crude oil desalting and dehydration.
The utility model crude oil ultrasonic wave-electric field associating desalter, comprise electrical desalter, ultrasonic wave active region, ultrasonic probe, supersonic generator, it is characterized in that on the pipeline before crude oil enters electrical desalter, the axis of the ultrasonic wave active region of installation is consistent with the flow direction of crude oil.
The axis of ultrasonic wave active region is consistent with the flow direction of crude oil, makes the crude oil that flows in pipeline can access hyperacoustic long effect.The crude oil flow direction can be identical with the ultrasonic wave action direction, also can be opposite.
The ultrasonic wave active region is the duct type structure, and end is the Taper Pipe district, and it is conical that internal structure is.The ultrasonic wave active region is to be connected and composed by flange by Taper Pipe district and straight tube district.Ultrasonic probe is installed in ultrasonic wave active region one end, connect by flange screw, the ultrasonic wave active region other end is the Taper Pipe district, make back wave that hyperacoustic reflecting surface forms can or not focus on and make emulsification of crude oil because of stack, thereby a kind of even action of ultrasonic waves district is provided, reaches the effect that improves desalination and dehydrating effect.
Advantage of the present utility model: compared with prior art, the utility model can provide a kind of uniformly and can prolong the ultrasonic wave ultrasonic wave active region of action time.Reach the effect that improves desalination and dehydrating effect.The results showed,, compare, can reduce crude oil and take off back saliferous and water content with simple electric desalting apparatus effect by ultrasonic wave-electric field associating desalter effect.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is the assembling schematic diagram of the utility model ultrasonic wave active region, probe.
Among the figure, 1, electrical desalter; 2, ultrasonic wave active region; 3, ultrasonic probe; 4, supersonic generator; 5, the straight tube district of ultrasonic wave active region; 6, the Taper Pipe district of ultrasonic wave active region; 7 crude oil inlet pipes.
The specific embodiment
Referring to Fig. 1, the utility model is made up of electrical desalter 1, ultrasonic wave active region 2, ultrasonic probe 3, supersonic generator 4.The installation direction of ultrasonic probe is the action of ultrasonic waves direction just, and is opposite with the flow direction of crude oil, and the axis of ultrasonic wave active region is consistent with the flow direction of crude oil.Electrical desalter 1, supersonic generator 4 are with prior art structure and working method.
Referring to Fig. 2, the ultrasonic wave active region is the duct type structure, is to be made of a straight tube district 5 and a Taper Pipe district, connects into the ultrasonic wave active region with flange mutually.Ultrasonic probe 3 is connected with ultrasonic wave active region 2 usefulness flange screws, and the reflecting surface of ultrasonic wave effect is the interior inclined-plane in Taper Pipe district 5.
The course of work is: the oscillation of power of the supersonic frequency that supersonic generator 4 produces is transferred to ultrasonic probe 3, and the ultrasonic probe radiating surface gives off ultrasonic energy, propagates along duct orientation in crude oil, acts on water, salt, crude oil in the crude oil.The reflecting surface on the interior inclined-plane in the Taper Pipe district 5 of ultrasonic wave active region 3 makes ultrasonic wave continue the far-end transmission to crude oil pipeline.Crude oil obtains uniform action of ultrasonic waves, and crude oil obtains long ultrasonic wave effect, and by hyperacoustic displacement effect, the salt in the crude oil separates with crude oil with water.Improved the effect of crude oil desalting and dehydration.And then enter electrical desalter through effect of electric field and gravitational settling, remove moisture in the crude oil, saliferous.
Generally speaking, frequency of ultrasonic is selected little to the influential effect of Desalting and Dewatering from Crude Oil, and frequency is higher, and ultrasonic wave is decayed easily, and frequency too low noise is bigger.Therefore the ultrasonic wave of general employing 15-50Khz is more suitable.In the production process, control hyperacoustic sound intensity and generally be not more than 0.5W/cm
2For different working conditions, the series connection of plural ultrasonic wave active region can be set, satisfy different production requirements.
