Description
Technical field
The present invention relates to a kind ofly with physical method emulsion be carried out the device of ultrasonic dehydration, especially a kind of device that crude oil in oil field or the oil plant production is carried out the ultrasonic dehydration dehydration.
Background technology
In the production and process of crude oil, one important operation is exactly water-oil separating, or claim to dewater, the key of dehydration is to manage to break in conjunction with Water-In-Oil tight, diversified in specifications, oil-in-water oil-water emulsion structure, this process just is breakdown of emulsion, behind the breakdown of emulsion again by other means, as: heat, sedimentation, staticize etc. profit is separated.At present, the chemical demulsification except generally using in the industrial production, promptly by outside the technology of adding a large amount of chemical demulsifiers realizations in emulsion, effect such as the cavitation that produces when utilizing ultrasonic wave effect liquid realizes breakdown of emulsion, is considered to a kind of effective breaking method.
CN2296230Y discloses a kind of " ultrasonic demulsifier of crude oil electric field dehydration ", it is made up of supersonic generator, ultrasonic wave active region, transmission cable and ultrasonic probe, the ultrasonic wave active region is a cylindrical shape or a square tube shape cavity that its axis direction is consistent with the treat liquid flow direction, ultrasonic probe is placed on the active region lateral wall consistent with the cavity axis direction by flange, and the action of ultrasonic waves direction is vertical with the flow direction of liquid.The shortcoming of this breaking device is that ultrasonic wave vertically acts on mobile emulsion, the effect time and be limited in scope, influenced the effect of breakdown of emulsion, simultaneously, ultrasonic waves transmitted is by the chamber wall reflection on opposite, form stack or focusing between the ultrasonic wave, intensity is wayward, even can cause the second emulsifying of processed liquid.
CN2539559Y discloses a kind of " crude oil ultrasonic wave one electric field associating desalter ", and it comprises electrical desalter, ultrasonic wave active region, ultrasonic probe, supersonic generator, crude oil enters on the preceding pipeline of electrical desalter, and the axis of the ultrasonic wave active region of installation is consistent with the flow direction of crude oil.The ultrasonic wave active region is the duct type structure, and end is not the Taper Pipe district, and it is conical that internal structure is.Ultrasonic probe is installed in the opposite in Taper Pipe district, the action of ultrasonic waves direction is consistent with the axis direction in Taper Pipe district, this scheme provides a single effect district that the ultrasonic wave action direction is consistent or opposite with liquid flow direction, the zone and the time of ultrasonic wave effect have suitably been increased, but structure is too complicated, ultrasonic wave is subjected to the restriction of single effect, and demulsification is still limited.
CN1589947A discloses a kind of " the ultrasonic combined effect of following current and adverse current makes the method and the device of oil-water emulsion breakdown of emulsion ", this scheme is provided with the ultrasonic wave active region of a duct type structure that is connected with the profit pipeline, at the two ends of duct type ultrasonic wave active region a ultrasonic probe is installed relatively respectively, supersonic generator takes place and the mobile ultrasonic adverse current ultrasonic wave that involves the profit flow inversion of following current in the same way of profit by ultrasonic probe, following current ultrasonic wave and adverse current ultrasonic wave act on the emulsion in the same ultrasonic wave active region of flowing through simultaneously, reach the purpose that makes its breakdown of emulsion.This scheme is owing to be provided with one two ultrasonic probes of relatively installing, can be along a profit flow direction and a reverse symphyogenetic active region, thus enlarged the scope of ultrasonication, prolonged action time, improved the effect of ultrasonic emulsion breaking.But the problem that this scheme exists is: two mutual correlation of ultrasonic probe that are oppositely arranged at two ends, synergy district along the emulsion flow direction, the two bundle ultrasonic waves that sent are very easily in inside, synergy district, especially mid portion forms stack, in case the intensity of stack reaches certain threshold values, not only can not breakdown of emulsion to the oil-water mixture of active region, and be likely further emulsification; For fear of the problems referred to above occurring, or limit the transmitting power of two probes, the operating potential that this will seriously limit supersonic generator and probe causes waste, and then the restriction demulsification; Will enlarge the length in synergy district on the structure as much as possible, and this can bring series of new problems such as installation, control and place restriction.
Summary of the invention
Reach the technical deficiency that easily causes second emulsifying in order to overcome existing oil-water emulsion breaking device demulsification difference, the invention provides a kind of hyperacoustic breaking device, this breaking device not only has demulsification efficiently, and can also prevent that ultrasonic wave from making profit produce second emulsifying.
The technical solution adopted for the present invention to solve the technical problems is: the supersonic generator that is provided with ultrasonic probe and is electrically connected with it, ultrasonic probe is installed on the transition jockey of tubulose, the two ends of transition jockey are connected with the preposition ultrasonic wave active region and the rearmounted ultrasonic wave active region of tubulose respectively, ultrasonic probe is made up of preposition ultrasonic probe and rearmounted ultrasonic probe, preposition ultrasonic probe institute ultrasonic waves transmitted only acts on preposition ultrasonic wave active region, and hyperacoustic transmit direction is opposite with liquid flow direction in the preposition ultrasonic wave active region, rearmounted ultrasonic probe institute ultrasonic waves transmitted only acts on rearmounted ultrasonic wave active region, and hyperacoustic transmit direction is identical with liquid flow direction in the rearmounted ultrasonic wave active region.
The present invention also can realize by following measure: preposition ultrasonic probe and rearmounted ultrasonic probe can also be installed in respectively on the chamber wall at transition jockey two ends.Preposition ultrasonic probe and rearmounted ultrasonic probe can also be fixed on the middle part of transition jockey cavity through supporting mass, and preposition ultrasonic probe and rearmounted ultrasonic probe adopt back-to-back direction to be installed in the left and right sides of supporting mass middle part.
The invention has the beneficial effects as follows, can utilize existing liquid conducting pipes, also independent cavity can be set, naturally two ultrasonic wave active regions have been formed, flow in the anterior cavity of transition jockey direction and formed a preposition ultrasonic wave active region, and in the rear portion cavity that flows out transition jockey direction, form a rearmounted ultrasonic wave active region, in the preposition active region adverse current to ultrasonic wave and rearmounted active region in act on the liquid of flowing through respectively with the ultrasonic wave that flows to, the ultrasonic wave that has only a direction in each ultrasonic wave active region is in super effect, two bundle action of ultrasonic waves directions are opposite, this has just thoroughly solved between the ultrasonic wave because phase mutual interference and stack, and then cause the problem of processed liquid second emulsifying, simple in structure.
