Example Embodiment

[0018] Embodiment 2 This embodiment is different from Embodiment 1 in that it further includes an internal electrode insulating layer 12, and the outer surface of the internal electrode 1 is covered with an internal electrode insulating layer 12.

Example Embodiment

[0019] Specific embodiment three, this specific embodiment is different from specific embodiment one in that it also includes a high-voltage inlet flange 13 mounted on the high-voltage junction box 4;

[0020] The high-voltage inlet flange 13 is fixedly connected with the high-voltage connection bolt 5 in the high-voltage junction box 4.

[0021] Using the crude oil dehydrator based on the magnetic field and uneven electric field of the present invention, the high-voltage power supply is connected to the high-voltage wiring bolt 2 and the grounding bolt 13 through the high-voltage inlet flange 12 in the Indian high-voltage junction box 1. The electrodes 6 are connected. When a high-voltage power supply is applied between the stainless steel inner electrode and the stainless steel outer electrode, an uneven electric field is established in the dehydration chamber 11; the excitation coil 5 is wound on the outside of the stainless steel outer electrode. No magnetic field is establishe...

Abstract

The invention provides a crude oil dehydrater based on a magnetic field and a nonuniform electric field, relating to crude oil dehydraters. According to the crude oil dehydrater, the problems that the existing crude oil dehydrater cannot carry out electric demulsification dehydration on the crude oil by utilizing the joint action of the magnetic field and the nonuniform electric field and the existing crude oil dehydrater cannot carry out electric demulsification dehydration on the crude oil by utilizing the electrophoresis action of the ununirom electric field are solved. An inner electrode is sheathed in an inner cavity of an outer electrode, a dehydration cavity is formed between the outer wall of the inner electrode and the inner wall of the outer electrode, one end of the outer electrode is connected with a high voltage terminal box through an insulation sealing gasket, the high voltage terminal box is internally provided with a high voltage terminal stud and an earth stud, the high voltage terminal stud penetrates through the insulation sealing gasket so as to be connected with the inner electrode, the earth stud is connected with the outer electrode, one end of the outer electrode, far away from the high voltage terminal box, is tightly connected with an end cover which is provided with a water outlet, an oil outlet and a liquid inlet are formed in the side wall of the outer electrode, and an excitation coil between the oil outlet and the liquid inlet is sheathed on the external surface of the outer electrode. The crude oil dehydrater can be widely applied to offshore crude oil dehydration.

Description

technical field [0001] The invention relates to a crude oil dehydrator. Background technique [0002] With the continuous growth of the national economy and the increasing demand for energy, the supply of oil has become a strategic issue affecting economic development. With the continuous reduction of onshore crude oil reserves, large oil production companies at home and abroad are turning their attention to the exploitation of offshore crude oil. At present, the crude oil dehydrator used on land in China adopts the structure of horizontal electrode and vertical electrode, and the electrode is generally composed of metal mesh or metal plate. The electric field between the electrodes is a uniform electric field. Under the action of AC voltage, the dehydration mechanism generally follows dipole coalescence and oscillation coalescence. Under the action of DC voltage, the dehydration mechanism generally follows the mechanism of dipole coalescence and electrophoretic coalescence...
