An intelligent control power panel can be used for setting a certain time period for inputting a high voltage of the electric-desalting and electric-dewatering device, so that the high-voltage current outputted by the transformer to an electrode panel in the tank is a variable high-voltage electric field continuously controlled by the controller, and the variable high-voltage electric field can be applied on the emulsion solution in the electric-desalting and electric-dewatering device to achieve emulsion breaking.
Description
Affiliated technical field
The utility model relates to the crude oil electric desalting apparatus for electrodewatering of a kind of oil field, oil plant, in particular it to relate to a kind of Based Intelligent Control power supply that adopts be the electro-desalting apparatus for electrodewatering of power supply.
Background technology
In petrochemical industry, for cutting down the consumption of energy, reduce equipment corrosion, Desalting and Dewatering from Crude Oil is the requisite important step in refinery and oil field.According to the high-pressure electrostatic coalescence principle, people have designed multiple desalting dewatering device, mainly contain alternating current desalination apparatus for electrodewatering and alterating and direct current desalination apparatus for electrodewatering at present.But because of present Chinese oil field and refinery's oil product more complicated, emulsifier is many, causes the emulsification of crude oil in refinery and oil field serious, the electrical conductivity height.After this kind crude oil enters the electro-desalting apparatus for electrodewatering, cause electric conductivity increase between pole plate, the transformer secondary electric current raises, simultaneously the transformer primary current also increases, and this moment, transformer reactance device self induction electromotive force rose, cause transformer once with the reduction of secondary voltage, electric-field intensity between the pole plate also reduces, often make between the pole plate of electro-desalting apparatus for electrodewatering to be short-circuited, cause unplanned shutdown, influence the normal operation of equipment.Though five grades in the transformer that adopts in alternating current desalination apparatus for electrodewatering and the alterating and direct current desalination apparatus for electrodewatering is adjustable, can not be continuously and adjust input voltage automatically.
Summary of the invention
The purpose of this utility model is to overcome deficiency of the prior art, provide a kind of can be to the continuous at any time self-adjusting crude oil electric desalting apparatus for electrodewatering of the electric-field intensity in the electro-desalting electric dehydration tank body.
Electro-desalting apparatus for electrodewatering of the present utility model mainly is made up of Based Intelligent Control controller, bidirectional triode thyristor, transformer and electro-desalting electric dehydrator.
The utility model is to realize like this, the 380V three-phase alternating current enters transformer through single phase ac bidirectional triode thyristor module, 220V single-phase electricity input intelligent controller, can transformer input voltage and duration be set according to arts demand by intelligent controller, magnitude of voltage is that 0～380V is adjustable arbitrarily, the duration section can be set to 99 sections (enough having satisfied instructions for use) at most, the high pressure of the electro-desalting of section input sometime electric dehydrator can be set on the panel of Based Intelligent Control power supply, after intelligent controller CPU sampling is calculated, send the control voltage signal of bidirectional triode thyristor by the voltage and current signal of feedback.Set value in the magnitude of voltage that the control bidirectional triode thyristor exports transformer to and the intelligent controller and be consistent, to export the high-tension electricity on jar interior battery lead plate to be to continue the variable high voltage electric field that is controlled by the controller to transformer like this.
The beneficial effects of the utility model are: (1) can adjust transformer output high pressure in any range, the electric-field intensity (2) that promptly changes in the tank body is impacted emulsion, improves Desalting and Dewatering from Crude Oil rate height (3) and reduces crude oil power consumption per ton.

The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is further described:
Three-phase alternating current inserts the internal electrical pole plate of electro-desalting apparatus for electrodewatering after entering electro-desalting transformer 3 after the bidirectional triode thyristor module 2 to become high-tension electricity, the intelligent controller 1 of 220V single-phase electricity input simultaneously, can transformer 3 input voltages and duration be set according to arts demand by intelligent controller 1, magnitude of voltage is that 0～380V is adjustable arbitrarily, the duration section can be set to 99 sections (enough having satisfied instructions for use) at most, the high pressure of the electro-desalting of section input sometime electric dehydrator can be set on the panel of Based Intelligent Control power supply, after intelligent controller CPU sampling is calculated, send the control voltage signal of bidirectional triode thyristor by the voltage and current signal of feedback.Set value in the magnitude of voltage that the control bidirectional triode thyristor exports transformer to and the intelligent controller and be consistent, to export the high-tension electricity on jar interior battery lead plate to be to continue the variable high voltage electric field that is controlled by the controller to transformer like this.When producing emulsion in the electro-desalting electric dehydration tank body, because the secondary high voltage of failing on pole plate is constantly to change, so the electric field in the tank body is also changing at any time, electric-field intensity is very high for a moment, very low for a moment, the effect of the electric field force that the little water droplet in the emulsion is subjected to is little when big also the time, and this has just produced a continuous percussion to emulsion, promote the breakdown of emulsion of emulsion, improved the Desalting and Dewatering from Crude Oil rate.Because of the high pressure of input is not to be stabilized in a very high constant, promptly in jar when emulsion is arranged, operating current is not high yet, greatly reduces electric energy loss.
Experiment showed, when adopting this kind high voltage source Based Intelligent Control crude oil electric desalting apparatus for electrodewatering that compare the alterating and direct current desalination, salt rejection rate improves more than 20%, crude oil power consumption per ton reduces by 30%.
