Description
The utility model relates to the dehydration of crude oil breaking device in a kind of oil field or the oil plant production, especially a kind of device that high viscosity oil is carried out the viscosity reduction breakdown of emulsion.
The problem that is subjected to the restriction of critical electric field strength to be difficult to improve for the dewatering efficiency that overcomes crude oil electric field dewater unit, notification number is that the utility model patent " crude dehydrating plant pulsed high frequency electric source " of CN2247044Y provides a kind of pulsed high frequency electric source, make and form high-frequency electric field intermittently in the electric dehydration jar between battery lead plate, replace original continuation electric field, thereby improved demulsification and dewatering efficiency.Make thus that oil content reduces exponentially in the sewage deviate from, and be applicable to the dehydration of high viscosity, high saliferous, wax-bearing crude.But because the AC and DC electric field does not have demulsification to water-in-oil type particle (O/W type emulsification structure), so that the water of deviating from still has the crude oil composition.Particularly at the later stage in oil field mining phase, adopt oil production method from liquid flux to the stratum that annotate high-temperature water, steam and, the oil of extraction has characteristics such as viscosity is big, impurity content is high, density is big, more is difficult to dehydration.Main cause is a this oily emulsification complex structure and stablizing, and is similar to the character of aging sump oil, contains Water-In-Oil, oil-in-water W/O/W type is besieged it ring upon ring structure.Dehydration problem to this crude oil also can't solve at present, even dehydration temperaturre is brought up to more than 80 ℃ from about 45 ℃, it is big to remain viscosity, is difficult to breakdown of emulsion, the chemical demulsifier effect is little, and above-mentioned CN2247044Y utility model patent is also powerless to this.
The purpose of this utility model is the oil at stable emulsifyings such as high viscosity, big proportion, gum level height and aging sump oils, a kind of efficient, simple viscosity reduction breaking device is provided, it is matched with pulsed high-frequency electric field dewater unit, within a short period of time with the moisture in the W/O/W type crude oil mixed liquor from coming out.
For realizing this purpose, the utility model adopts following technical scheme; A kind of ultrasonic demulsifier of crude oil electric field dehydration, it is made up of supersonic generator (1), ultrasonic wave active region (2), transmission cable (3) and ultrasonic probe (4), ultrasonic wave active region (2) is a cavity that is connected on electric dehydration jar front, and ultrasonic probe (4) is installed on the outer wall of this cavity and by transmission cable (3) and links to each other with supersonic generator (1).
Ultrasonic probe (4) is to be connected with flange (7) on being welded on ultrasonic wave active region (2) chamber outer wall by supported flange (9) to be installed on the chamber outer wall.
Ultrasonic probe is a plurality of, can be installed in equably on the chamber outer wall, the ultrasonic frequency of each radiation of popping one's head in is all identical with power, also can be divided into plurality of sections by the front and back of cavity, each section adopts the probe of different model, makes the ultrasonic frequency of each section probe radiation all different with power.
The utility model utilizes the cavitation effect of ultrasonic wave in liquid, the ultrasonic wave active region is set before the electric dehydration jar, when a large amount of cavitation bubbles that cavitation effect produces break, the huge force of explosion that is produced, liquid group in the mixed liquor is smashed, be about to the micel that Water-In-Oil, oil-in-water besiege it ring upon ring and smash, become small drop state, reach breakdown of emulsion and reduce the purpose of viscosity.Through evidence, the process that adopts ultrasonic wave that crude oil is carried out the viscosity reduction breakdown of emulsion only needs the time in several seconds to tens of seconds, than fast hundreds of times with chemical demulsifier, so not only save a large amount of demulsifier expenses, boost productivity, and, also can bring into play useful effect to the immalleable mal-condition of demulsifier.
Further specify the utility model below in conjunction with accompanying drawing and by embodiment:
Fig. 1 is the structural representation of embodiment;
Fig. 2 is the connection diagram of ultrasonic probe and chamber outer wall;
Fig. 3 is the scheme of installation of ultrasonic wave active region and ultrasonic probe.
Embodiment, ultrasonic wave active region 2 is mounted in the cavity of electric dehydration jar 6 fronts, and it is connected with pipeline 5 by flange with the electric dehydration jar.Supersonic generator 1 is connected with ultrasonic probe 4 on being installed in chamber outer wall by transmission cable 3, as shown in Figure 2, ultrasonic probe 4 is to be connected by the flange 7 on the outer wall 8 of supported flange 9 and welding ultrasonic wave active region 2 to be installed on the outer wall of ultrasonic wave active region.The cavity of ultrasonic wave active region 2 can be made different shapes such as cylindrical shape, square tube shape according to the different of flow, pressure, oil and environmental condition of wet crude.Several of ultrasonic probe 4 general employings, can install equably, and make the ultrasonic frequency of the radiation of respectively popping one's head in all identical with power, also can be divided into 2 to 3 sections by the front and back of ultrasonic wave active region cavity, each section adopts the probe of different model, makes the ultrasonic frequency of the institute's radiation of respectively popping one's head in all different with power.
The course of work of the present utility model is: supersonic generator 1 produces superaudible oscillation of power signal, send ultrasonic probe 4 to through transmission cable 3 and convert corresponding supersonic frequency mechanical oscillation to, radiation end face 10 by probe is injected the ultrasonic wave active region with ultrasonic energy, a large amount of in the contacted local generation of emitting facet 10 and liquid, cavitation bubble, these bubbles are breaking one after another along with in the moving of acoustic energy flow and liquid stream, thereby produce a large amount of micro-waves.These continuously micro-wave just become the motive power of breakdown of emulsion, make the preliminary viscosity reduction breakdown of emulsion of high viscosity oil, enter the electric dehydration jar again and carry out deep dehydration, the deep dehydration here promptly is to adopt aforesaid CN2247044 patent to carry out processed.Can just reach qualified dehydrating effect without chemical demulsifier like this.
Generally speaking, when ultrasonic frequency one regularly, produce what of cavitation bubble quantity, be directly proportional with the input electric power of ultrasonic probe, so the ultrasonic power size of input is to determine according to the processing oil mass of oily difference and electric dehydrator.Consider power one in addition regularly, when ultrasonic frequency was low, the cavitation bubble that is produced was few and force of explosion is strong, was fit to destroy the emulsification structure than general objective that viscosity is big, besiege it ring upon ring.When frequency was high, the cavitation bubble of generation was many and a little less than the force of explosion, but can touch more tiny emulsion group.Therefore in order to improve the action effect of ultrasonic dehydration, between hundreds of KHz, based on crude oil and emulsification structural shape select the ultrasonic wave of one or more frequencies to carry out radiation to the ultrasonic frequency that the ultrasonic wave active region is applied at 16KHz.In order to strengthen demulsification, also can on same pipeline, use with two active regions (with supersonic frequency identical or inequality) string, can also use with the active region of same frequency is in parallel.
