The invention relates to the treatment and purification of water systems with magnetic zero and can be used in technological schemes for the preparation of water systems at high pressures, for example, in the oil-producing, chemical, heat-and-power industry.

The purpose of the invention is to increase the efficiency of the device by combining the processes of cleaning water systems and their treatment in a magnetic field.

Figure 1 shows the device section; figure 2 - section aa in figure 1; on fig.Z - diagram of the installation of the device at the mouth of the injection wells.

The device comprises a diamagnetic case 1, in which along the inner and outer perimeter and in the volume there are segment magnets 2 made of rare-earth materials. In the volume, the magnets are placed in a checkerboard pattern with a constant decrease in the distance along the length of the body. Between the magnets there is a ferromagnetic attachment 3 and a corrosion-resistant magnet of a soft or rigid spherical material with a constant decrease in the diameter of MGJFpa balls from 8 mm to 1 mm, or spiral-like chips of large sizes from 10 mm to small i mm along the length of the body. The nozzle is bounded at both ends of the housing with gratings 4. A diamagnetic housing with a magnet-sh and us, is mounted with a bracket 5 on the flange cap 6 of the outer

magnetically conductive casing 7, which has a nozzle with a flange 8. The input of the device is connected to the supply unit 9, Segment magnets located along the outer perimeter

the cases are divided among themselves by annular sleeves 10 of the diamagnetic material.

The device works as follows.

The water system from the conduit through the flange 9 enters the body 1 of the device. The leakage through the ferromagnetic nozzle 3, iron-containing mechanical impurities under the action of a three-dimensional magnetic field gradient is deposited and fixed on the surface of a spherical or sprayed jet; casings and external magnetic casing 7; where it is processed in a magnetic field that is created by segmented magnets. 2 turn; polished polarity, located on the outer perimeter of the housing 1. Magnetic field lines of force

they are directed normally to the flow of the water system and are closed on the external magnetic conductive casing 7. Through the branch pipe - with the flange 8, the water system flows further into the water conduit.

The arrangement of magnets in a staggered order with a gradual decrease in the distance between the poles and the one-dimension. reduction in fer3 size

magnetic nozzle along the length of the body provides a change in the magnetic field gradient according to the law

J grad B f,

where induction on the surface of the nozzle; o is the distance between the elements

The nozzle porosity also varies exponentially, which ensures uniform deposition of coarse particles in the upper zone of the device, and particles of colloidal sizes are deposited in the lower zone. Therefore, when cleaning water systems over time, alignment of the porosity of the nozzle occurs. When reducing the flow area of sediment from the device must be removed. The purified water system, subjected to treatment in a magnetic field, becomes less corrosive due to the change in physicochemical properties.

Rare earth magnets are characterized by the highest magnetic energy and strength. Therefore, the use of rare earth magnets ensures high efficiency of the device for a long time. The annular sleeves 10 of diamagnetic material prevent the magnetic from being displaced along the generatrix of the outer surface of the housing 1 when creating a pressure drop in the installation.

For installation of the unit at the mouth of the injection well, the distributing conduit 11 from the pumping station is used, the manifold is on the valve 12, the valve 13, the valve 14 for sampling water, inlet 70

pressure gauge 15, water treatment system 16, sample pressure gauge 17, outlet sampling valve 18, manifold

valve 19, production column 20, water supply well 21 and annular valve 22 (fig. 3), through system 11 through the open valve 12, the water system enters the installation where the extraction of iron-containing mechanical impurities and the treatment of water systems is provided, and through the open valve 19 is supplied into the well 21. The resulting sediment leads to a decrease in the flow area in the device, resulting in an increase in flow resistance. On the output gauge 17 compared to

the inlet 15 pressure increases with respect to the pressure difference P |. - R, 5 judges that the nozzle of the device needs to be regenerated. To remove sediment from the device, shut off valve 12,

opening the buffer valve 13.

The use of the device in the circulating cycle conduits in the injection line at the well head will ensure high-quality and efficient processing of water systems during the flood period, and the injection wells will not be shut off during the flood period, which will ensure the required oil production rates.

Significant differences and advantages of the proposed design of a device for magnetic treatment of aqueous systems as compared with the known technical solutions consist in obtaining an additional effect, which is achieved by combining the processes of cleaning water systems and processing them in a magnetic field.
