Abstract

The invention relates to an electrostatic coalescer for separating oil from water, which belongs to the field of a crude oil processing device, and is provided with a cylinder body, wherein the bottom part of the cylinder body is provided with an oil outlet, the top end of the cylinder body is provided with an oil inlet, a filter and a safety valve are installed on a top cover of the cylinder body, and the electrostatic coalescer is characterized in that: a high-voltage junction connector is fixed on the upper side wall of the cylinder body, a cylindrical insulation electrode B, a grounding electrode B, an insulation electrode A and a grounding electrode A are sequentially nested inside the inner cavity of the cylinder body from outside to inside, wherein the upper end and the lower end of the insulation electrode B, the upper and the lower ends of the grounding electrode B, the upper and the lower ends of the insulation electrode A and the upper and the lower ends of the grounding electrode A are respectively provided with an insulation top plate and an insulation soleplate, the insulation electrode B and the insulation electrode A are electrically connected with the high-voltage junction connector, and the grounding electrode B and the grounding electrode A are electrically connected with the cylinder body. By adopting the electrostatic coalescer, rapid separation of the oil and water can be realized through the electrostatics without utilizing chemical substances.

Description

technical field [0001] The invention relates to the field of petroleum crude oil treatment devices, in particular to an electrostatic coalescer for water and oil separation that processes small water droplets in petroleum crude oil into large droplets. Background technique [0002] As we all know, many oil fields in my country have entered the late stage of crude oil exploitation, and the output crude oil has high water content. Due to serious emulsification, it is difficult to separate oil and water. If chemical substances are used, it will cause pollution. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides an electrostatic coalescer for oil-water separation that can realize rapid oil-water separation through static electricity without using chemical substances. [0004] The technical scheme adopted by the present invention to solve the technical problem is: an electrostatic coalescer for oil-water se...
