Description

 The invention relates to the oil industry, in particular to a device for the magnetic processing of oil in order to prevent asphalt-resin-paraffin deposits on ground and underground oilfield equipment, to reduce the corrosive activity of the produced fluid.

 The device can also be used in power engineering, water supply to prevent scale formation, for magnetic desalination of water and its activation, in the enrichment of minerals, etc.

Closest to the proposed device is a magnetic fluid treatment, comprising a ferromagnetic casing, a frame made of non-magnetic material placed inside the casing, and permanent magnets in the form of rods of rectangular cross-section, mounted in rows along the axis of the casing and fixed to the frame with non-working end surfaces with the formation of working gaps between the main surfaces magnets [1]
The disadvantage of this device is the low efficiency of magnetic processing of the liquid due to the irrational use of the capabilities of the magnetic system of the device.

 The aim of the invention is to increase the efficiency of magnetic processing by maximizing the use of the capabilities of the magnetic system and providing the ability to control the magnetic field in the working gap.

 To this end, in a device for magnetic fluid treatment, comprising a ferromagnetic housing, a frame made of non-magnetic material placed inside the housing and permanent magnets in the form of rods of rectangular cross-section, mounted in rows along the housing axis and fixed to the frame with non-working end surfaces with the formation of working gaps between the main surfaces of the magnets , the permanent magnets of one row are set with respect to the magnets of the other row at an angle, while the main surfaces of the magnets of one row and facing e them major surfaces of the adjacent row of magnets made with opposite magnetization.

 The invention ensures maximum use of the capabilities of the magnetic system, namely: when the magnetic field is formed in the liquid treatment, both main surfaces of each permanent magnet in each row of the device participate, the frame in which the permanent magnets are attached is installed outside the working gaps and overlaps the section of the housing where the magnetic field is practically absent; the magnetic field is regulated in the working gaps.

 The drawing shows a device for magnetic fluid processing, a cross section.

 The device comprises a ferromagnetic casing 1, inside of which there is a frame 2 made of non-magnetic material and permanent magnets 3. The frame 2 consists of two parts with segmented sections, which are installed inside the casing 1 against each other and with convex surfaces mating with the inner surface of the casing 1. On flat surfaces the frame 2 is made recesses 4. Permanent magnets 3 are made in the form of rods of rectangular cross section, while the magnetic poles are located in the main surfaces of the magnets. The magnets 3 are fixed in the recesses 4 of the frame 2 with non-working end surfaces, mounted parallel to the axis of the housing in rows forming working gaps 5 between the main surfaces of the magnets 3. Neighboring magnets 3 in each row are installed with a gap, and their poles are reversed both between themselves and relatively 3 magnets in the opposite row. Between the outer main surface of the magnets 3 in the extreme rows and the inner surface of the opposite portion of the housing 1, additional working gaps are formed 6. Permanent magnets 3 in adjacent rows are set at an angle to ensure the regulation of the magnetic field in the working gap.

 The device operates as follows.

 In the working gaps 5 and 6, magnetic fields are formed perpendicular to the direction of fluid flow through the device, and the direction of each field is opposite to the direction of the adjacent field.

Due to the fact that all the main surfaces of the magnets in all rows participate in the creation of magnetic fields, the maximum use of all the capabilities of the magnetic system in the operation of the device is ensured. The entire magnetic flux of the optimal magnitude is concentrated in the working gaps and with the maximum effect the entire cross section of the device is used for efficient processing of the fluid flow. The efficiency of permanent magnets in the device is 95-98%
This device can also be used for deep pumping oil production, having performed a working gap greater than the diameter of the pump rod.
