Cylinder electrode electrostatic coalescer

Abstract

The invention relates to the technology of an electrostatic coalescer, in particular to a cylindrical electrode electrostatic coalescer. A cylindrical electrode electrostatic coalescer, the coalescer has a cylindrical shell and an electrode located in the shell, the electrode includes an inner electrode and an outer electrode rolled into a cylinder by elastic metal, and the inner electrode is provided with There is an inner electrode insulating layer, and the outer electrode is provided with an outer electrode insulating layer. One end of the housing is provided with an inlet for high-voltage insulated wires, and the other end is an inlet for oil-water emulsion. On the side of the housing, there is a The outlet of the oil-water emulsion, the inner electrode is connected to the high-voltage end of the external transformer through the inlet of the high-voltage insulated wire, and the shell is grounded. The speed of the oil-water emulsion flowing through the present invention becomes slower, the residence time in the electric field becomes longer, and the force of the electric field is greater, the water droplets in the oil fully collide and coalesce, merge into larger particles and settle out, and the oil-water separation efficiency is improved.

Description

Technical field [0001] The invention relates to electrostatic coalescer technology, in particular to a cylindrical electrode electrostatic coalescer. Background technique [0002] Electrostatic coalescing device is an indispensable part of the oil-water separation system of each oil field. Most oil and gas treatment stations and joint stations in my country currently use traditional electric dehydrators, but traditional electric dehydrators have the following problems: (1) ) Requires high input voltage; (2) The cost and floor space of the equipment are large; (3) The energy consumption is large, and the safety and stability are poor. In summary, 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 reform it. [0003] There are two main overall structures of the existing electrostatic coalescers: one is an indepe...
