Embodiment Construction

[0015] see figure 1 , figure 2 with image 3 Shown is an electric desalination and dehydration tank of the present invention. The electric desalination and dehydration tank includes a tank body 1, and an electrode 2 is arranged inside the tank body 1, and the electrode 2 is a horizontal plate electrode, and two layers are arranged. The lower layer of electrodes 2 is connected to the high-voltage output end of the transformer 7, and the upper layer of electrodes 2 and the tank body 1 are grounded. The tank wall at the bottom of the tank body 1 is provided with an oil-water mixture inlet pipe 3 and a drain pipe 5 , and the tank wall at the top of the tank body 1 is provided with an electrical desalination and dehydration oil material outlet pipe 6 .

[0016] In the lower part of the tank body 1, there are at least three sets of stable drains 4 along the axial direction of the tank body 1; figure 1 , figure 2 As shown, 6 groups of stable drainers 4 are set. Each group of ...

Abstract

The present invention discloses a kind of electric desalting and dewatering tank for use in oil field and oil refinery, and aims at reducing oil in exhausted water of electric desalting and dewatering tank. The electric desalting and dewatering tank has inside the tank at least three axial water exhaust stabilizing devices in the bottom, and each of the water exhaust stabilizing devices consists of metal plate and lattice. The metal plate is perpendicular to the tank axis and has two ends connected to the inner wall of the tank, and there is gap between the plate and the tank wall for deposited water to flow through. The lattice set in the top of the metal plate consists of metal strips perpendicular to the metal plate. The present invention is used mainly for desalting and dewatering raw oil.

Description

technical field [0001] The invention relates to an electric desalination and dehydration tank used in oil fields and refineries. Background technique [0002] The water and metal salt compounds contained in crude oil will corrode the equipment during processing. Therefore, the salt and water contained in crude oil must be removed before processing. The device used is the electric desalination and dehydration tank. At present, domestic and foreign oil fields and refineries basically use horizontal electric desalination and dehydration tanks, and the electrode forms used mainly include horizontal plate electrodes, vertical suspension electrodes and single-layer or multi-layer squirrel-cage electrodes. In these electric desalination and dehydration tanks, the oil-water mixture basically enters the tank from the lower part of the tank and is dehydrated by an electric field; the desalted and dehydrated oil is discharged from the upper part of the tank. The water droplets overcom...
