The invention relates to mechanical engineering and can be used for magnetic treatment of liquids in pipelines and devices in the supply of hydrocarbon fuel in internal combustion engines, as well as in power and water supply.

A device for magnetic treatment of fluids containing successively installed axially magnetized annular permanent magnets separated by washers made of magnetic material, the innermost line hydrocod and the screen covering the outside magnetic system (and.with. The USSR №1134550).

A disadvantage of this known device is the low efficiency of processing liquid due to the fact that you created an axially magnetized annular permanent magnets, the magnetic field in the working gap along the length of the gap has a different amplitude of tension. In this field there is no local concentration of the magnetic field in the working gap.

It is also known a device for magnetic treatment of fluids, comprising a housing, an electromagnet, tubular coil, characterized in that the housing is made in the form of a truncated cone of non-magnetic material and a solenoid wound on its surface, wherein the tubular coil is made of non-magnetic material and located inside the housing in the form of a tapered helix (patent RF �2181699). The novelty of this technical solution is caused by moving the tube through which flows a fluid, outside the solenoid, where the magnetic field is spread out, inside the solenoid, where the magnetic field is concentrated, and the magnetic field strength increases from the center of the solenoid to the periphery, where the tube is in the form of a tapered helix, which flows manicavasagar liquid.

The disadvantage of this device is that is used a tapered helix, significantly increasing the size of the device, and that in each area of fluid motion requires the presence of the bounding walls, within which the fluid moves. A significant disadvantage of this device is the use of an electromagnet, which eliminates the use of this device in places where there is no power.

There is also known a device with a stratified water treatment Rostov Institute of railway transport engineers. In the apparatus of this type the water passes through the annular gap. The apparatus consists of two outer lengths of pipe, between which is arranged concentrically of the ring of magnetic iron, the components of the left and right of the ring system, are displaced relative to each other. These rings are magnetized by an external coil. Flux Le�Oh and right systems is distributed through the main cores and short inserts between the rings. The gaps between the rings of the left and right magnetic systems decreases from the periphery to the center; this is achieved by equality of the average magnetic field in all the gaps. Field in the inhomogeneous gaps (Klassen V. I. Magnetization of water systems. - M., Chemistry, 1978, PP 240).

A known device of the type AMO is a diamagnetic trough, located between the five C-shaped electromagnets. They eat regular (in some cases alternating) current. The field strength 64-160 kA/m (800-2000 e), flow rate (depending on pressure) of 0.8-2.8 m/s; the height of the slurry flow 800-100 mm, output devices of different sizes 100-250 m3/h. Devices of this type are designed to handle slurry (pulp) (Klassen V. I. Magnetization of water systems. - M., Chemistry, 1978, PP 240).

The advantages of magnetic water treatment electromagnetic field are obvious: high performance, satisfactory quality water purification. The disadvantages include high energy costs, the complexity of structures (for a magnetic induction of up to 2 Tesla in the working chamber with a diameter of 2 m power consumption is 500 kWh, and the total mass (weight) - 400 t), the need for highly professional service, hazardous effects of EMF on the human body.

Closest to the claimed device to the technical nature of the state.�STI (prototype) is a device for magnetic treatment of liquids comprising a housing connected to a piping for supplying and discharging fluid, mounted inside the magnetic unit in the form of a set of permanent magnets enclosed in a cylindrical housing, between the magnetic unit and the housing is formed with a channel for passage of fluid flow (patent RU 69512 U1, published 27.12.2007). The housing of the magnetic unit is installed in the device housing with an annular gap and provided at the ends of the pointed conical tip, the device is provided confuser-diffuser stabilizers liquid, consisting of a conical narrowing of the plot in the form of a confuser, the cylindrical portion of the narrowing and widening of the plot in the form of a cone.

The disadvantages of this device is that when the flow of liquid may not work all the magnets of the magnetic unit due to the different velocities of fluid flows, washing the magnetic unit and the resulting phenomena of water hammer and cavitation processes lead to instability of velocity and volume of flowing fluid, which degrades the quality of the treatment last. The low efficiency of the processing fluid occurs because of the fact that created an axially magnetized annular permanent magnets, the magnetic field in the working gap along the length of the gap has a different amplitude of tension. � such a field there is no local concentration of the magnetic field in the working gap.

The object of the invention is to improve the efficiency of magnetic treatment of fluid flow.

The technical result of the invention is the magnetization of the fluid flow, including time-varying speeds and all physico-chemical properties, by increasing the concentration of magnetic flux and amplification of the magnetic field in the working gap of greater length, as well as eliminating the effect of reducing the impact of the permanent magnets on the properties of the liquid to be treated.

The above technical result is achieved in that in the proposed device for combination of magnetic treatment of fluids, comprising a housing connected to a piping for supplying and discharging fluid and mounted inside the magnetic unit as a set of permanent magnets between the magnetic unit and the housing is formed with a channel for passage of fluid flow, the specified channel for the passage of fluid flow is made in the form of a spiral with a frequency step equal to six, the length of the magnetic unit commensurate with its diameter, and between the ring magnets of the magnetic unit has a ferromagnetic strip, and the number of annular permanent magnets in a magnetic block is three, and the pipes for supplying and discharging the fluid ustanovlenytakie on the basis of Helmholtz coils with reactive power compensators.

Device for magnetic treatment of fluids comprising a housing connected to a piping for supplying and discharging fluid, which are Helmholtz coils. Helmholtz coils differ from conventional coils in that they provide a uniform electric field along the axis of the coil. Helmholtz coils and coils have inductance and consume reactive power. To reduce the consumption of reactive power and improve cosφ use the reactive power compensator made in the form of a capacitor connected to the Helmholtz coil in series or in parallel (Smirnov, A. D., K. M. Antonov Reference book power. - M.: Energoatomizdat, 1984, pp. 419-422). Inside the hull is a magnetic unit in the form of a set of permanent magnets of a certain chemical composition, covered with a thin layer of Nickel. The magnetic unit is installed in the device housing with a spiral gap with a multiplicity of steps equal to six, and provided at the ends of the pointed cone tips and stabilizers of the fluid flow in the form of distributive lattices. The magnetic unit consists of magnetized disks in an amount equal to N =3n. The length of the magnetic block must be equal to its diameter within a factor of 0.9-1,20.

It is known that high efficiency of magnetic treatment of fluids about�especially under the following conditions applicable to the configuration of the magnetic field in the working gap of the device:

- high magnetic field strength in each antinode;

- high tension gradient at each antinode;

- the possibility of wide variations database of a magnetic device with preservation of the size and shape of the antinode of the magnetic field.

It is established that the fulfillment of these conditions depends on the mutual arrangement of the annular permanent magnets along the ferromagnetic body and the effectiveness of additional elements, providing the penetration of the magnetic field in the working gap, their local concentration and homogeneity in cross-section of the working gap. These properties of the device for combination of magnetic treatment of fluid flow provided by the proposed design features. If single annular magnet (as in the prototype) is characterized by a smooth transition between the polar opposites of the same maxima of the magnetic field, the apparatus further from one of the ends without a gap of at least two annular magnets ferromagnetic rings greatly enhances one maximum magnetic field strength at the expense of weakening other minor redistribution of energy between them. Due to this, inside the housing, where the fluid flows, is formed a series of local �of ucnokta tension axial magnetic field. The amplitude of tension in such loops is almost twice higher than that of the single ring magnets (prototype). While the boundaries of these adjacent loops are described in more drastic decay of the magnetic field, i.e. the growth of their gradients. Moreover, this regularity is in General characteristic of the totality of ring magnets in the proposed device. This allows for highly efficient magnetic treatment of liquids with different physical-chemical properties and different flow rates, including variable flow rate.

In addition, the mounting of the device housing with pipes for supplying and discharging fluid may be formed flange or by means of a swivel nut.

The essence of the invention is illustrated by drawings, which shows a General diagram of the device for combination of magnetic treatment of liquids.

The device for combination of magnetic treatment of a fluid includes a housing 1, a cover with inlet and outlet nozzles, which are electromagnets 4 on the basis of the Helmholtz coils 5 and block 6 consisting of three ring magnets, which are located between two ferromagnetic strip 7 with a thickness of 1 mm, are bonded together with a pointed conical tip 8, the two plates 9 and pin 10. According to the form�e of the invention, the number of annular permanent magnets in the General case must be equal to N =3n, where n=1, 2, 3... is a natural integer. The concept of the natural (whole) number was introduced by Euclid (third century BC) and is the conventional designation n=1, 2, 3...(M. J. Profitable. Handbook of elementary mathematics. -M.: Nauka, 1986, p. 44). The formula is N =3n also means that the number of annular permanent magnets is a multiple of 3, i.e. 3, 6, 9, etc. Between the device and a magnetic block 6 are spiral channels with six inputs and six outputs, designed for transport of the processed liquid.

The device for combination of magnetic treatment of liquids is as follows.

The treated liquid is fed into the device for combination of magnetic treatment from a main pipe with a certain velocity through the inlet 2 and a distribution grid 9 in a spiral channel of movement formed by the housing 1 with a spiral gap and a magnetic block. Being in the zone of influence of the permanent magnets, the fluid passes to the outlet of the device through the outlet 3 to the processing magnetic field at least 3 times. The treatment effect is amplified by the fact that the shape of the spiral channels is chosen so as to obtain a twisting of the fluid flow at the entrance to the zone location of the magnetic block is not dependent on the flow velocity at the inlet, i.e. the path of the fluid in two-t�and times more than ramjet, and, accordingly, increases proportionately and the potential impact of magnetic fields on fluid particles.

The device for combination of magnetic treatment of liquid has all the advantages of magnetic devices based on permanent magnets, i.e. there is no significant power operation, since the power to the electromagnets is carried out through reactive power compensators, provided ecological purity, simplicity in manufacture and operation.

The device for combination of magnetic treatment of fluids, comprising a housing connected to a piping for supplying and discharging fluid and mounted inside the magnetic unit as a set of permanent magnets between the magnetic unit and the housing is formed with a channel for passage of fluid flow, characterized in that the specified channel for the passage of fluid flow is made in the form of a spiral with a frequency step equal to six, the length of the magnetic unit commensurate with its diameter, and between the ring magnets of the magnetic unit has a ferromagnetic strip, and the number of annular permanent magnets in a magnetic block is three, and the pipes for supplying and discharging the liquid set the electromagnets on the basis of Helmholtz coils with reactive power compensators.
