Plate electrode static coalescer

Abstract

The invention relates to the technical field of static coalescers, in particular to a plate electrode static coalescer.The late electrode static coalescer is characterized in that the upper portion of the coalescer is a high-voltage electricity input section, the lower portion of the coalescer is a coalescing section, the high-voltage electricity input section is provided with an observation chamber made of insulating organic glass, the upper end of the observation chamber is provided with a high-voltage insulating wire inlet, the bottom of the observation chamber is provided with an insulating wiring groove, a stainless steel shell is arranged below the observation chamber, the shell and an insulating electrode and a bare electrode which are located in the shell form the coalescing section, and the insulating electrode is connected with the high-voltage end of an external transformer through the insulating wiring groove and the high-voltage insulating wire inlet.The plate electrode static coalescer has the advantages that the speed of water-oil emulsion passing the coalescer becomes low, the staying time of the water-oil emulsion in an electric field becomes long, large electric field force effect is achieved, water drops in oil sufficiently collide and coalesce and are combined into large particles which are then settled, and oil-water separation efficiency is increased.

Description

technical field [0001] The invention relates to electrostatic coalescer technology, in particular to a flat electrode electrostatic coalescer. Background technique [0002] The electrostatic coalescence device is an indispensable part of the oil-water separation system in various oil fields. Most of the oil and gas processing stations and combined stations in my country currently use traditional electric dehydrators, but the traditional electric dehydrators have the following problems: (1 ) requires a high input voltage; (2) the cost and floor area of ​​the equipment are large; (3) the energy consumption is large, and the safety and stability are poor. To sum up, the traditional electric dehydration equipment (electrostatic coalescer) has been difficult to meet the production requirements. As the difficulty of crude oil dehydration continues to increase, it is imperative to update and transform it. [0003] There are two main structures of existing electrostatic coalescers: ...
