Description

The invention relates to the oil industry, relates to structural features of the device for the magnetic activation of liquid media, in particular crude oil or water, and can be used to prevent complex organic and mineral deposits on ground and underground equipment, to break emulsions, and also to reduce corrosion activity of the treated fluid.

From the application WO 95/11198 A1, C 02 F 1/48, E 21 B 37/00, 04/27/1995 there is known a device for magnetic fluid treatment, designed to be installed on the surface of a pipeline for a liquid and containing a sealed non-magnetic housing in which the constants are placed magnets inducing an axial magnetic field, and there are essentially no magnetic cores. However, this device is not intended for its installation inside the pipeline for the processed fluid.

From the patent RU 2098604 C1, E 21 B 37/00, C 02 F 1/48, 12/26/95, a device for magnetic processing of liquid media is known, comprising a cylindrical body, along the axis of symmetry of which are installed radially magnetized ring permanent magnets that create a magnetic field, the direction of the magnetic lines of force which is perpendicular to the direction of movement of the processed fluid through the pipeline.

However, in this device, the passage hole for the fluid being treated is significantly narrowed, and the inner passage hole

absent, which excludes the possibility of installing the device outside (outside) of the pipeline for the processed fluid.

From patent RU No. 2085507 C1, C 02 F 1/48, 07/27/1997, a device for magnetic fluid treatment containing a ferromagnetic pipe and compound ring permanent magnets having radial magnetization that are covered by a sealed ferromagnetic screen and installed in pairs on its outer surface is known. In this case, pairs of ring permanent magnets are installed along the length of the ferromagnetic pipe at a distance not less than three times the width of one ring magnet, and the main surfaces of each of them last are conjugated with the outer surface of the ferromagnetic pipe.

A significant drawback of this device is the absence of the action of the Lorentz force on the electrically charged components of the processed fluid, since the directions of its motion and the axial magnetic field lines are parallel. In addition, the scope of this device is limited, since it is not possible to install it inside the pipeline for the liquid to be treated.

From patent RU No. 2127708 C1, C 02 F1 / 48, 03/20/1999 a device for magnetic fluid processing is known, adopted as a prototype, containing a ferromagnetic pipe and installed on its outer surface radially magnetized, annular permanent rings detachable along the axis, from one end of each of which additional ferromagnetic rings are installed without a gap, while the axis of the ferromagnetic pipe faces the same poles of the ring permanent magnets, and their outer poles are shunted by ferromagnetic plates, which are installed Lena uniformly without gap on the outer surface of the annular permanent magnets. Given

the device has the simplicity of its installation and dismantling without stopping the process in hard-to-reach conditions.

The magnetic fields generated by this device are directed mainly parallel to the direction of movement of the processed fluid through the pipeline. In this case, however, significant disadvantages of this device are the impossibility of installing the device inside the pipeline, as well as the incomplete use of magnetic fluxes of permanent magnets, since magnetic cores are adjacent to the permanent magnets from their ends. This arrangement of the magnetic cores leads to a gradual change in the direction of magnetization of the magnets and loss of operability of the device.

The technical result to which the present invention is directed is to increase the processing efficiency of moving liquid media, as well as to increase the service life of the proposed device while expanding the scope of its use.

This technical result is achieved by the fact that the proposed device for the magnetic treatment of moving liquid media, containing a sealed housing in which radially magnetized permanent magnets and magnetic circuits are installed, according to this invention, can be located both inside and outside (outside) the pipeline for the processed fluid, while the sealed housing is made with an internal bore in the form of two coaxial cylinders of different diameters, at the ends of which plugs are installed, each standing This magnet and magnetic circuit is supported by a sealed housing and is made in the form of a sector with an opening angle of 90 ° -120 °, with an external arc diameter equal to the internal diameter of the external cylinder of the sealed housing, and with an internal arc diameter equal to the external diameter of the internal cylinder of the sealed housing, permanent magnets are arranged in pairs diametrically opposite to the longitudinal axis of symmetry of the sealed housing, and also symmetrically on both sides of the magnetic cores along the longitudinal axis of symmetry of the sealed

housings, permanent magnets of each pair have a opposite direction of magnetization and are supported on the surface of the sealed housing by poles of opposite polarity, and permanent magnets of different pairs, placed on opposite sides of the magnetic cores, but on one side of the longitudinal axis of symmetry of the sealed housing, are supported by poles of the same name polarity.

Moreover, according to the invention, the dimensions L1 of each of the permanent magnets, L2 of each of the magnetic cores and the distance L3 between them along the longitudinal axis of symmetry of the sealed enclosure correspond to the following relationships:

L1 = (1-0.7) D1;

L2 = (0.3-0.5) D1;

L3 = (1-0.7) D1

provided D2-D1 = (2-0.5) cm,

where: D1 is the inner diameter of the inner pipe, m .;

D2 - outer diameter of the outer pipe, m.

The inner and outer cylinders of the sealed housing can be made in the form of pipe segments of circular cross-section made of ferromagnetic, or diamagnetic, or paramagnetic material, in particular steel and alloys.

In addition, the device can be provided with centering supports for its installation inside the pipeline for the fluid to be treated coaxially, while the outer and inner surfaces of the cylinders of the sealed housing must be coated with non-ferromagnetic materials, and the outer diameter D2 of the outer cylinder

sealed casing is connected with the inner diameter D3 of the pipeline for the fluid being treated by the ratio:

0 <D3-D2 <(1 / 2D3)

The device can also be made with the possibility of installing outside (outside) the pipeline for the fluid to be processed, while the inner diameter D1 of the inner cylinder of the sealed housing coincides with the outer diameter D4 of the pipeline for the processed fluid, and the cylinders of the sealed housing are made of ferromagnetic materials, or as an inner cylinder sealed housing can be used piping for the processed fluid.

In addition, according to this invention, the free space in a sealed enclosure can be filled with a substance, for example, cement stone, which provides the necessary stability of the device structure to deformation and additional protection of permanent magnets and magnetic circuits from environmental influences.

The invention is illustrated by drawings, where figure 1 shows a longitudinal section of the proposed device, figure 2 is a cross section of the device, figure 3 is a possible placement of the device inside the pipeline for the liquid to be treated, figure 4 is a possible placement of the device outside (outside) the pipeline for the fluid to be treated.

The device for magnetic processing of liquid contains a sealed housing 1, consisting of two coaxial cylinders, in particular from pipe segments of different diameters, at the ends of which plugs are installed (not shown in the drawings), as well as radially magnetized permanent magnets 2 and magnetic cores located in the sealed housing 1 3.

Permanent magnets 2 and magnetic cores 3 are made in the form of sectors with opening angles of 90 ° -120 °

The recommended number of permanent magnets in the device is in the range of 8-18 pieces.

The device can be equipped with centering supports 4. The free space in the sealed housing of the device can be filled with a substance that provides the necessary stability of the structure to deformation and protection of permanent magnets and magnetic circuits from external influences, for example, cement stone.

The cylinders of the sealed housing 1 can be made of ferromagnetic, diamagnetic and paramagnetic materials, for example, steels and alloys. The choice of cylinder material is determined by the location of the device outside (outside) or inside the pipeline with the processed fluid.

The dimensions of the permanent magnets and magnetic circuits along the longitudinal axis of symmetry of the sealed enclosure are selected from the above relationships: L1 = (1-0.7) D1;

L2 = (0.3-0.5) Dl;

L3 = (1-0.7) D1,

provided D2-D1 = (2-0.5) cm,

where D1 is the inner diameter of the inner pipe, m;

D2 - outer diameter of the outer pipe, m

When placing the device inside the pipeline, it is installed on the centering supports 4 coaxially to the pipeline for processing

liquids. In this case, it is permissible that the external diameter of the device casing D3 and the internal diameter of the pipeline D4 are within:

0 <D4-D3 <(1 / 2D3)

The external and internal surfaces of the cylinders of the sealed housing 1 of the device should be made of non-ferromagnetic materials (figure 3).

When placing the device outside the pipeline for the fluid to be treated, the inner diameter D1 of the inner cylinder of the sealed housing coincides with the outer diameter D4 of the pipeline for the processed fluid, that is, D1 = D4, and the cylinders of the sealed housing must be made of ferromagnetic materials, or as the inner cylinder of the sealed housing of the device used pipeline for the processed fluid (figure 4).

In the presented drawings (FIGS. 2, 3 and 4), continuous closed lines with arrows show the directions of the magnetic field lines with various methods of mounting the device

The proposed device for magnetic processing of liquid provides exposure to the liquid in the entire region of its flow along this device with strong (up to 1-1.5 T) magnetic fields that do not have axial symmetry, perpendicular to the direction of motion of the processed liquid, periodically change their direction to the opposite and have high gradients not only in the direction of flow, but also perpendicular to it. This eliminates the relaxation processes that occur after the cessation of the magnetic field, leading, as is known, to a decrease in the effect of magnetic treatment. In this case, the processed fluid located in the area of the magnetic device is constantly exposed to a variable amplitude and gradient

magnetic field, and charged fluid particles are constantly exposed to the Lorentz force, since the direction of fluid motion is perpendicular to the magnetic field created by the permanent magnets of the installation. Due to the presence of magnetic cores made of ferromagnetic materials with a high coefficient of magnetic permeability and located between the permanent magnets at a certain distance, the magnetic field in the pipeline for the fluid to be processed between the diametrically located magnetic cores in the casing has a high tension close to the field strength in the pipeline between the diametrically arranged permanent magnets . The combination of these physical factors allows for more efficient magnetic processing of a mixture of oil and water, as well as gas.

The possibility of placing the proposed device inside or outside (outside) the pipeline allows you to more fully use the magnetic flux of permanent magnets due to the fact that the walls of the pipeline serve as magnetic cores. With the proposed arrangement of magnetic cores and permanent magnets, magnetization reversal of the latter is excluded,

In addition, the possibility of arranging the proposed device both inside and outside (outside) the pipeline for the fluid being treated expands the conditions for its use when there are technological limitations for the external or internal diameter of the pipeline. Due to the presence of an internal bore in the device, no significant hydrodynamic resistance is created, while the energy of the magnetic field induced by permanent magnets in the device of the proposed design is used more fully.
