Abstract

The invention provides a crude oil electric dehydration high voltage power supply device, relates to crude oil electric dehydration high voltage power supply devices, and aims at solving the problems of continuous discharge of high voltage dehydration electrodes, collapse of high voltage dehydration electric fields and increasing of capacity requirement of the high voltage power supply devices during crude oil electric dehydration process. The crude oil electric dehydration high voltage power supply device performs pressure regulating and current-limiting on low voltage alternating current and then performs boosting through a high voltage transformer, two paths of high voltage outputs of the high voltage transformer are rectified by a first high voltage silicon stack and a second high voltage silicon stack, formed into high voltage direct current with positive polarity and negative polarity, and output to a high voltage fast pulse unit. A microprocessor control unit judges whether dehydration electrodes form ripples according to voltage and current monitoring values and controls switching of the high voltage fast pulse unit. Under a normal dehydration condition, the high voltage fast pulse unit outputs direct current with positive and negative polarity, and when short circuits are caused by existence of ripples, the high voltage fast pulse unit exerts batch-type high voltage large current pulse to load till the ripples are opened, and accordingly electric fields in a dehydration container are recovered. The crude oil electric dehydration high voltage power supply device is applied to the crude oil processing process.

Description

technical field [0001] The invention relates to a power supply device, in particular to a high-voltage power supply device for electric dehydration of crude oil. Background technique [0002] Crude oil dehydration is an important link in the process of crude oil processing. At present, electric and chemical dehydration methods are mostly used in various oil fields. The applied voltage is AC or DC high voltage. The power supply methods generally include AC dehydration, DC dehydration and AC-DC dehydration. As the oil field enters the stage of high water cut production, the tertiary oil recovery technology is widely used in various oil production plants. In the electrical dehydration process of ASP flooding, due to the addition of alkali / surfactant / polymer ternary compound agent, the conductivity and viscosity of crude oil are increased, which makes the dehydration of crude oil more difficult. These substances tend to adhere to the insulating rods of the dehydration container...
