Description

The invention relates to techniques for magnetic processing of liquids and can be used for magnetic processing of water and liquid petroleum products and oil.

A device for magnetic fluid processing, comprising a housing in the form of a pipe made of diamagnetic material and an electromagnet in the form of a winding on the housing in several layers with phase displacement, a power supply and control unit containing a thyristor converter and a thyristor converter control circuit. The processed fluid flows inside the casing and is exposed to a magnetic field during the residence time of the fluid in the casing of the device (USSR Author's Certificate No. 865832, priority date 01.25.1980, publication date 09/23/1981, authors Grach I.M. et al., RU) .

A disadvantage of the known device is the low efficiency of magnetic processing of the liquid due to insufficient contact of the liquid with the magnetic field inside the housing, since it crosses the fluid flow only in the end sections of the winding on the electromagnet body, and between them inside the body the direction of the magnetic field coincides with the direction of fluid movement, and the effect of the magnetic field on the liquid is low.

The closest in technical essence and the achieved result is a device for magnetic fluid treatment, comprising a housing made of diamagnetic material and an electromagnet mounted on the outside of the housing in the form of coaxially placed windings connected taking into account phases, a power supply and control unit, the housing inside is equipped with a turbulator in the form of fixed blade screws made of diamagnetic material, which are placed relative to each other in an inverted position (RF Patent No. 2238910, priority date 12/16/2003, publication date 10/27/20 04, authors Khaziev N.N., Shaydakov V.V. et al., RU, prototype).

The disadvantage of the prototype is the lack of efficiency of processing the liquid with a magnetic field, since it depends on the geometric parameters of the fluid flow.

The objective of the invention is to increase the efficiency of processing a fluid in a magnetic field by creating a rotating magnetic field and fluid flow.

To solve the problem in a device for magnetic fluid treatment, comprising a housing of diamagnetic material and an electromagnet connected to a three-phase network, installed in the pipeline by flange connections, according to the invention, the housing is prefabricated, in which a stator is installed, containing a core with a coil made of cylindrical forms creating a rotating alternating magnetic field, while a thin-walled cylinder made of diamagnetic material is coaxially installed inside the stator , the ends of which are hermetically connected to the device flanges, and a thin-walled corrugated cylinder inserted into it with a corrugation arranged along a helix, mounted on a pipe with plugs on which the ends of the corrugated cylinder are hermetically connected, the pipe is made of paramagnetic material and fixed in the ends installed in the connecting flanges stops equipped with holes for the passage of fluid.

According to the invention, the electromagnet can be made in the form of two stators installed along the length of the device casing and connected by flanges.

According to the invention, the direction of rotation of the alternating magnetic field in the stators may coincide with or be opposed to the direction of rotation of the flow of the magnetically treated fluid.

According to the invention, the stators are installed with the possibility of creating an alternating magnetic field in them with a different direction of its rotation.

The drawing schematically shows a device for magnetic fluid treatment with two stators.

A device for magnetic fluid processing includes a housing 1, in which a stator 2 is installed, comprising a core with a winding made of a cylindrical shape. The device may contain one or two stators interconnected by flanges 3. Washers 4 are attached to opposite ends of the housing 1, to which the flanges are connected 5. Inside the stators, a thin-walled cylinder 6 is made of diamagnetic material, for example, copper or stainless steel, the ends of which are hermetically sealed mounted on flanges 5 by flashing using glue. Inside the thin-walled cylinder 6 is a corrugated cylinder 7 made of diamagnetic material, mounted on a pipe 8 with plugs 9 made of steel. At the same time, the ends of the corrugated cylinder 7 are flared on the plugs 9, and the pipe 8 with plugs 9 is fixed against movement with the stops 10 installed in the connecting flanges 11 of the pipe 12. The stops 10 are made with holes 13 for entering and exiting fluid from the device. Flanges 11 and 5 are tightly interconnected using sealing and bolted joints.

A device for magnetic fluid processing works as follows. The device is connected to a pipeline through which the fluid to be magnetically processed is transported. After mounting the device on the object, an alternating voltage is applied to the windings of the stators, which creates a rotational magnetic field in the cores 2, the direction of which can change due to a change in the voltage phase. The fluid to be magnetic is fed through the openings 13 of the stop 10 and flows through the helical cavities of the corrugated cylinder 7, acquiring a rotational movement. The rotational motion of the liquid may coincide with the direction of the magnetic field or is directed in the opposite direction. The fluid flowing through the corrugated cylinder 7 is subjected to repeated exposure to a pulse of an alternating magnetic field and prolonged exposure due to rotation and an increase in the path of movement, it enters the main pipeline through the holes 13 of the stop 10 installed in the flange 11. The operation mode of the device is selected by adjusting the fluid supply, as well as a change in the direction of rotation of the magnetic field.

An advantage of a device for magnetic fluid treatment with two stators is that the efficiency of fluid treatment in a magnetic field is increased, since the exposure time of an alternating magnetic field pulse, the path length and the residence time of the fluid in a magnetic field are increased, and it is also possible to create an alternating magnetic field in stators with different directions of rotation.

Thus, the creation in the device of a rotating magnetic field of a variable frequency and a thin fluid flow can increase the efficiency of magnetic processing by increasing the frequency of exposure to the magnetic field and the duration of exposure.
