Description

The device is designed for magnetic processing of liquids and can be used in heat engineering, chemical, oil and gas industries, as well as in the field of engine building to increase the energy parameters of fuel. There are various devices for this purpose.

A device for magnetic fluid processing (patent RU No. 2180894, IPC C2F 1/48, 2000) is known. The known device comprises a housing located in the housing to form a working channel, a ferromagnetic rod, a magnetic system made in the form of blocks of permanent magnets mounted on the rod, with this, the permanent magnets of each block are mounted on a ferromagnetic rod with the formation of a ring and oriented by the same poles to the surface of the ferromagnetic rod, on the outside each block of permanent magnets is covered by a monolithic casing and non-magnetic material made in the form of a spindle, and the permanent magnets are placed in the part of the casing having a maximum diameter, and the pointed end of the casing is oriented towards the fluid flow in the working channel, while cylindrical non-magnetic monolithic bushings are installed on the ferromagnetic rod from each end of the block of permanent magnets, made with screw channels on the outer side surface.

The disadvantage of this device is the inefficient treatment of the liquid with a magnetic field, because a helical fluid flow is characteristic of laminar flows, in this case there is no fragmentation of the liquid molecules and treatment with a magnetic field is ineffective. As a result, the access of oxygen to fuel molecules, for example, gasoline, is limited during its combustion, regardless of the incoming amount of air. The quality of processing the magnetic field of the laminar flow is 3-8 times lower than the quality of processing the turbulent flow.

The closest set of essential features and adopted as a prototype is a device for magnetic fluid processing (patent RU No. 2261230, IPC C2F 1/48, 2004). The known device contains a magnetic field source and a housing in which ferromagnetic concentrators of magnetic field lines are located at a distance from one another. The magnetic field source installed in the housing consists of one or several sections located with the formation of flow channels, with the magnets of the parallel sections facing each other with opposite poles, and the magnetic field line concentrators located in each of the flow channels are made in the form of rods.

Analysis of the technical characteristics of the prototype showed that along with the known advantages, there are significant disadvantages. Significant disadvantages of this device are:

1) the use of concentrators as mechanical turbulators of the fluid flow, because this leads to a noticeable complication of the design with low efficiency ("Hydraulics and Pumps" O.V. Baibakov, O. I. Zeegofer, State Power Publishing House, Moscow, Leningrad, 1957, pp. 59-78);

2) the use of concentrators to create an uneven field in the flow channel with a simultaneous narrowing of the flow cross section by 70%, which results in the need to increase the magnetic gap to 6 mm with the inevitable decrease in the magnetic field induction in the working gaps and to increase the scattering fields around the periphery of the working magnets, as well as problematic, even impossible, preventive maintenance - flushing, repair, etc. without completely disassembling the device;

3) splitting the flow of the treated fluid into a series of parallel flows to achieve the desired flow area is inefficient due to the short length (about 30 mm) of the working channels and is technically difficult.

An object of the invention is the creation of a structurally and technologically simple device with an increase in the quality of the magnetic treatment of the liquid, which allows the efficient use of the liquid for subsequent use.

The stated technical problem is achieved in that in a device for magnetic fluid treatment, comprising a housing and a magnetic field source, in which the magnetic field source is made in the form of parallel magnet modules with a hole installed in series with the formation of a zigzag-shaped flow channel (for a fluid flow ) with alternating directions of the magnetic field, which ensures turbulization of the flow of the treated fluid due to hydrodynamics, while the magnets of the modules are facing yr other opposite poles. The number of magnet modules is set depending on the type of fluid being processed and the degree of magnetization. The distance between the magnet modules is determined by the bandwidth of the device, and the number of holes in the module is one or more, while the hole of each subsequent magnet module is shifted with a turn relative to the hole of the previous magnet module.

The essence of the technical solution is illustrated by the drawing, which schematically shows a device for magnetic processing of liquids, a General view. The claimed device contains a housing 1 and a magnetic field source consisting of modules of magnets 2, which are located parallel to each other. The magnets 3 of the modules 2 are facing each other with opposite poles. The channel formed by the construction of the modules for the passage of the processed fluid (dashed line) has a zigzag shape. Case 1 has an input 4 and an output 5 fittings. The magnet module has an opening 6 formed by a washer 7 and magnets 3. The number of holes can be one or more. The magnet modules 2 are mounted in the housing 1 in such a way that the opening of the subsequent magnet module is offset from the opening of the previous magnet module. This arrangement provides a zigzag shape for the fluid duct.

An example of the device. As the processed liquid automobile fuel can be used - gasoline or diesel fuel.

The housing 1 may be made of soft magnetic steel. The magnetic field source is made in the form of a set of identical modules, the construction of which in assembled form provides a zigzag path of the processed fluid. The magnetic field source consists, for example, of nine modules of non-magnetic material, for example, an aluminum alloy D16 t with fixed disk magnets with a diameter of 13 mm and a thickness of 3 mm. The magnet material is a neodymium-iron-boron (NdFeB) alloy. The total length of the working channel through which the fluid flows is more than 200 mm with a modular assembly length of 54 mm. The proposed zigzag shape of the working channel provides hydrodynamic turbulization of the flow without narrowing the bore, which reduces the magnetic gap to 3 mm, the loss on the scattering field is reduced by half ("Permanent magnets", Reference. AB Altman, A.N. .Gerbarg, P.A.Gladyshev, edited by Yu.M. Pyatin. "Energy", Moscow, 2nd edition, 1980, pp. 202-211 "Calculation of magnets without reinforcement by the equivalent solenoid method"). The correctness of the proposed algorithm for calculating the magnetic field induction in the gap of a given configuration was empirically confirmed by testing a prototype of a device in which magnets were used: disk, diameter d = 13 mm, thickness L = 3 mm, induction B = 1.3 T, magnet material is neodymium alloy iron boron (NdFeB).

An example of a device of nine modules.

M _o - magnetic constant M _o = 4P × 10 ^-7 GN / m

M - magnetization of a magnet

The following calculation algorithm is proposed: B = f (y):

1. Given: Vm = 1.3 T; d = 13 mm; L = 3mm

2. Accept ratio ;

We present the calculation of the magnetic induction B for two values of the gap b:

The proposed method for calculating the magnetic induction in the working gap formed by two parallel magnets facing each other with opposite poles is applicable to disk magnets of any standard size. It can be seen from the table that with increasing distance, the magnetic induction decreases, so when choosing the distance between the magnets, it is based on how much fluid should pass through the channel and what should be the magnetic induction of the field in this channel to ensure effective processing of the liquid. The following tables explain the choice of distance between magnets.

The number of magnet modules is determined depending on the type of fluid being processed, for example, automobile fuel, oil, water, etc., as well as the degree of magnetization. The distance between the magnet modules is determined by the bandwidth of the device. The greater the bandwidth of the device, the greater the distance between the magnetic modules.

The claimed device operates as follows.

The flow of the processed fluid, for example, automobile fuel, through the inlet 4 enters the housing 1 and then moves along the zigzag flow channel perpendicular to the magnetic field lines. The flow is turbulized due to hydrodynamic drag due to the shape of the flow channel. In a turbulent flow, groups of molecules rub together and collide, which leads to their partial decomposition, a decrease in viscosity and an increase in the volume fraction of fuel and, ultimately, an increase in the activity of fuel in oxidative reactions. Treated with a magnetic field, the fuel through the nozzle 5 exits the housing 1.

As a result of the implementation of the claimed technical solution, we obtain a device that is easy to manufacture (the device is simple structurally and technologically). The fuel processed using this device is better atomized, burns out more completely, which increases engine power, reduces exhaust toxicity, and reduces fuel consumption by 15-20%.
