Technical field
The utility model relates to and a kind of crude oil emulsion is carried out the electric demulsification device of breaking emulsion and dewatering, can be used for the desalting and dewatering and the oily water separation of crude oil in oil field, the petroleum chemical enterprise.
Background technology
Water mainly exists with water in oil emulsified state in crude oil, the stability that this milk sap had is having a strong impact on the natural separation of crude oil and water, the method of employing breakdown of emulsion is broken the emulsified state of crude oil and water formation, is that crude oil and water carry out isolating precondition.
The method of breakdown of emulsion has a lot, as chemical demulsification, centrifugal breakdown of emulsion, heating demulsification type, high-voltage electrostatic demulsifying etc., but adopt high-voltage electrostatic demulsifying to have breakdown of emulsion efficient height, low, the advantage of simple technology of cost, thereby in the crude production and the course of processing, use the dehydration equipment of high-voltage electrostatic demulsifying widely, using maximum is exactly crude oil electric desalting/hydrophone.
Oil variety is changeable, the use and the treatment capacity of crude oil heaviness, oil recovery auxiliary agent improve greatly, make that crude oil electric desalting/hydrophone volume is increasing, the electric field pole plate of breakdown of emulsion becomes increasingly complex, cause breakdown of emulsion efficient more and more lower, cause desalination/water deleterious, with regard to its basic reason is to cause that voltage descends, and causes the reduction of electric field to the breakdown of emulsion ability of crude oil emulsion because electric desalting/water power stream increases.Increase strength of electric field can improve the breakdown of emulsion ability to crude oil emulsion, but because the maximization of equipment and pole plate is complicated, increase strength of electric field certainly will cause the increase that rolls up, invests of power consumption, and the technical limitation of power-supply unit makes it to become possibility simultaneously.Thereby provide more effectively that breakdown of emulsion equipment is the task of top priority.
CN88200107U novel high-voltage electrostatic demulsifying device electrode adopts the board-like electrode vertical parallel of insulation to be arranged in the liquid level of breakdown of emulsion tank.The feed(raw material)inlet flows into, and oil phase flows out from the upper end outlet, and water flows out from the lower end outlet.The advantage of this emulsion treater provides the emulsion treater of a kind of breakdown of emulsion and sedimentation one, but because the restriction of structure, can only small-scale treatment capacity, can't carry out large-scale treatment capacity.
ZL01277410.3 milk sap eddy flow high voltage pulse static continuous demulsification device, adopt solid electrode and conducting electrolyte to constitute electrode pair, obtain the high voltage pulse electrostatic field, by tangentially milk sap being pressed into emulsion treater, make milk sap self produce cyclonic action, thereby make the milk sap for the treatment of breakdown of emulsion obtain centrifugal field.The advantage of this emulsion treater is that high voltage pulse electrostatic field and centrifugal field combine, and has greatly strengthened the demulsification of milk sap.Shortcoming when pending emulsus liquid measure is big, can cause the volume of emulsion treater to increase for can only handle less milk sap, makes structure become complicated.
The utility model content
At the deficiency that existing Desalting and Dewatering from Crude Oil device exists, the utility model provides a kind of electric demulsification device, and this electric demulsification device is simple in structure, can produce high strength breakdown of emulsion electric field, improves breakdown of emulsion efficient.
