Description

 The invention relates to the fuel and energy, food industry and can be used for water treatment of heat exchange and washing units.

 A device for magnetic water treatment, including a magnetic system of an electromagnet, a metal case for the passage of treated water (see, for example, Klassen V.I. Magnetization of water systems. - 2nd ed. Revised. M .: Chemistry, 1982, p. 155).

 The reasons that impede the achievement of the technical result indicated below when using the known device include the fact that in the known device, the effectiveness of magnetic treatment of water depends on the quantitative ratio of the chemical components of water, so water containing sulfates is less susceptible to magnetic treatment.

 The closest device of the same purpose to the claimed invention in terms of features is a device for protection against scale formation, comprising a magnetic system, an electrode electrically connected to a generator of high-frequency bipolar oscillations, a dielectric pipe (see AS 1579907, class C 02 F 1 / 48, 5/14. Akolzin A.P., Anufriev N.G., Kozlova T.V. et al. Method of protection against scale formation of pipe surfaces, heat exchangers and tanks in aqueous media. Published on July 23, 90, Bulletin No. 27). and taken as a prototype.

 For reasons that impede the achievement of the technical result indicated below when using the known device adopted as a prototype, the distribution of the electric field between the plates in the known device is not uniform, the dielectric pipe for the passage of the treated water has low mechanical strength, especially with an increase in the transverse dimensions of the device, power high frequency oscillations low.

 The invention consists in the following. It is known that water is a dispersed system, the particles of which are crystallization centers during scale formation on the inner surfaces of aggregates. Under the action of a magnetic field, particles are crushed and a large number of crystallization centers are formed, and crystallization occurs in the volume of water, and not on the walls. Magnetic treatment lends itself well to carbonate water. In order to expand the range of processed compounds in water, the effect of a high-frequency electric field is additionally used. As a result of this effect, liquid vibration occurs, weakening the connection of the components (see, for example, AS 523713, class B 03 C 5/00, C 02 B 3/00, Smirnov OV, Rukobratsky N.I. , Lavrov I.S. et al. Method for the electrical treatment of a disperse system. Publish. 05.08.76. Bull. N 29). However, for a more efficient use of a high-frequency electric field, it is necessary that the treated water receive the same effect throughout its route in the device. The power of high-frequency oscillations is maximum with a rectangular pulse shape (meander shape), respectively, the effect on dispersed particles is enhanced. To process a large amount of water, the device significantly increases its overall dimensions and reliability decreases due to the presence of a section of the water supply from a dielectric material, less mechanically strong metal structures.

 The technical result obtained by carrying out the invention is expressed in the uniform effect of high-frequency oscillations of a rectangular shape of an electric field and in increasing the reliability of operation.

 The specified technical result in the implementation of the invention is achieved by the fact that in the known anti-scale formation device containing a magnetic system, an electrode electrically connected to a generator of high-frequency bipolar signals, a dielectric pipe, the feature is that it is additionally introduced into it a conductive housing for water passage, the magnetic circuit so that the magnetic circuit is axially located in the conductive housing and is part of the magnetic system of the electromagnet, and the dielectric the first nozzle axially located in the housing adjoins the magnetic circuit from the side of the treated water supply, and the electrode is coaxially mounted on the dielectric nozzle and the conductive housing is electrically connected to the generator of high-frequency bipolar oscillations, and the oscillations of the generator have a rectangular shape.

A causal relationship between the set of essential features listed above from the claims, and the above technical result is as follows. The gap between the dielectric pipe and the conductive housing is much smaller than the diameter of the dielectric pipe with an electrode mounted on it, and therefore a uniform uniformly distributed high-frequency electric field is created in the gap. With the passage of water in the gap of the device, all layers of water receive the same effect from the electric field. The rectangular shape of high-frequency oscillations in the shape of the meander acts more intensively on the treated water, so compared with a simple harmonic signal y (x) = sinx when the meander is expanded in a Fourier series, we get
y (x) = 4 [sinx + sin3x / 3 + ...] / π> sinx
(see, for example, Andre Ango. Mathematics for electrical and radio engineers. Second edition, stereotyped. M: Nauka, 1967, p. 88).

 In addition to the water supply function, the conductive housing is at the same time a supporting structure, since it is made of metal, the structure's resistance to mechanical loads is increased. Thus, the reliability of the device is increased.

The drawings show:
- in FIG. 1 shows a device for protection against scale formation;
- in FIG. 2 shows a section AA of this device.

 Information confirming the possibility of carrying out the invention to obtain the above technical result are as follows.

 The device comprises a conductive housing 1 made of diamagnetic material, a magnetic circuit 2 axially located in the conductive housing 1, a dielectric pipe 3, axially located in the housing 1 and adjacent to the magnetic circuit 2 from the supply side of the treated water, an electrode 4 coaxially mounted on the dielectric pipe 3, magnetic an electromagnet system 5, located on the housing 1: a rectangular high-frequency generator of different polar oscillations 6, an insulator 7, pin 8, and a generator 6 is electrically connected to the housing m 1 on the one hand and the electrode 4 on the other side through the pin 8 in the insulator 7, a tip 9, adjacent to an insulating pipe 3.

 The operation of the device is as follows. High-frequency bipolar oscillations of a rectangular shape from the generator 6 come on the one hand through contact 8 in the insulator 7 to the electrode 4 and to the conductive housing 1 on the other hand. Since the electrode 4 is placed on the dielectric pipe 3 adjacent to the magnetic circuit 2, the electrode 4 and the housing 1 form the capacitor plates with a gap between them for the passage of water. Water at the entrance to the device is dissected by the tip 9 and is uniformly treated first with a high-frequency electric field in the gap, and then with the magnetic field created by the magnetic system of the electromagnet 5.
