Exit collector of smoothing electrodesalting and electrodehydrating device

Abstract

The invention discloses an exit collector of a smoothing electrodesalting and electrodehydrating device, aiming at solving the problem that the salt content and water content of the crude oil pumped from the tank body via an oil pipeline are higher due to collecting the crude oil with higher salt content and water content existing in the current open pore baffle type exit collectors. The exit collector (2) of the invention is composed of a vertical pipe (21) and a horizontal pipe (22) to be of a reverse T shape, the cross sections of the vertical pipe (21) and the horizontal pipe (22) are round; the column surfaces of the vertical pipe and the horizontal pipe are provided with round open pores (23); the bottom of the vertical pipe is connected with the column surface of the horizontal pipe, and the top thereof is connected with an oil outlet pipe (1) which is arranged at the top end of the exit of a tank body of the smoothing electrodesalting and electrodehydrating device; and the exit collector is arranged at the upper part in the exit of the tank body of the smoothing electrodesalting and electrodehydrating device. The exit collector of the invention is suitable for the smoothing electrodesalting and electrodehydrating device, and the smoothing electrodesalting and electrodehydrating device adopting the exit collector of the invention is mainly applied to crude oil electrodesalting and electrodehydrating in oil fields and oil refineries.

Description

technical field [0001] The invention relates to an outlet collector used in flat current desalination and dehydration equipment. Background technique [0002] At present, electric desalination and dehydration equipment is widely used in oil fields and refineries at home and abroad to remove salt and water contained in crude oil. There are many kinds of electric desalination and dehydration equipment, one of which is advection electric desalination and dehydration equipment. figure 1 Shown is a flat current desalination and dehydration equipment, which includes a tank body 3, the two ends of the tank body 3 are caps, and the tank body 3 is provided with an oil inlet distributor 6 and an electrode 4 along the direction from the inlet end to the outlet end. The electrode 4 is arranged above the oil-water interface 8, and is fixed on the inner wall of the tank body 3 by insulating support and hanging. The tank body 3 is provided with an oil inlet pipe 5, an oil outlet pipe 1 a...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide an outlet collector of advection electric desalination and dehydration equipment, so as to solve the problem that existing open-hole baffle-type outlet collectors have the problem of collecting crude oil with high saline content and high water content through the oil outlet pipe. The crude oil extracted from the tank has a high salt and water content, and the tank is divided into an oil collection chamber, which makes the structure of the tank more complex and the oil collection chamber is inconvenient to maintain.
