Description

FLOW-THROUGH MAGNETIC CELL

AND DEVICE FOR MAGNETIC TREATMENT OF FLUID MEDIA BASED THEREON

Field of the Invention

This invention relates to structures of flow-through magnetic cells and based on these cells devices for magnetic treatment of fluid media.

For the purpose of this description, the following terms as employed herein and in the appended claims refer to the following concepts:

(a) «Fluid medium)) refers to:

Firstly, gaseous and easy-flowing liquid preferably hydrocarbon pure or composite substances (in particular, natural or coke oven gas, propane, butane and their mixtures, synthetic gas, petrol, diesel fuel, aviation kerosene, gasohol etc.), which use as fuels for internal-combustion engines and heating equipment or as raws for chemical synthesis,

Secondly, water from various natural and artificial sources (especially, hard and/or contaminated by pathogenous microflora);

Thirdly, Newtonian liquids in the form of various true solutions, and,

Fourthly, easy-flowing aerosols and liquid suspensions or emulsions, which can include natural and/or artificial fine-dispersed mechanical impurities;

(b) ((Magnetic treatment)) refers to pumping of a selected fluid medium trough at least one gap between permanent magnets fixed in any proposed further devices for the purpose of alteration of physicochemical properties of this medium;

(c) «Magnetically-treated)) refers to any fluid medium after magnetic treatment;

(d) ^(Source of fluid medium)) refers to any vessel containing a stock of a fluid medium (e.g., a gasholder or a gas bottle, a fuel tank of any transport vehicle, a water storage reservoir etc.), or to an active pipeline having at least one branch pipe equipped with suitable shut-off-and-regulating element; and

(e) ((Consumer of fluid medium)) refers to any gas cooker, an internal-combustion engine, a water boiler, a steam generator, and other fuel-burning heater etc.

It is necessary to keep in mind too, that used hereinafter definitions such as «upper» and «lower», « horizontal » and «vertical» and the like refer only to the relative position of images of component parts of known or proposed devices on the cited and appended drawings.

Prior Art

Impact of magnetic field on physicochemical properties of substances was discovered by Van der Vaals in early XX century. Further many physicists have attempted to provide theoretical justification of this impact (e.g., .L.I. Schiff and H. Snyder, Physical Review, 55, 59, 1939) and to ascertain excitation of molecules of chemical compounds by magnetic fields (e.g.. Dong Lai, Edwin E. Salpeter Hydrogen molecules in a superstrong magnetic field: Excitation levels // Physical Review A, v.53, No.1 , 1996, pp.152-167).

Now it is well-known that magnetic treatment alters structure of water and increases its chemical and biological activity. So, magnetically-treated water increases rate of chemical reactions, intensifies absorption of gases (especially, oxygen), crystallization of dissolved substances and coagulation of other impurities and their sedimentation in the form of fine- dispersed particles (that is the most significant for prevention of scale formation). Moreover, magnetically-treated water increases permeability of cellular membranes of plants and animals. This activates metabolism, decreases content of cholesterol in blood, and promotes normalization of arterial pressure, removal of small nephrolithes, cure of dermatopathia, arthropathies, many diseases of the lungs etc.

Similarly, magnetic treatment of hydrocarbons intensifies their combustion, increases efficiency of any heating equipment, decreases amount of carbon dioxide, carbon-black and non-combusted hydrocarbon segments in combustion products and, thereby, promotes reduction of specific fuel consumption.

In essence, magnetic treatment is elementary. Fluid medium must be incubated during some time in (or pumping through) a sufficient gap between poles of strong magnets and then can be used according to its intended purpose.

However, costs of production and mounting, mass, total dimensions, serviceability and repairability, and efficiency of devices for magnetic treatment depend substantially on kind, geometrical shape and chemical composition of magnets and their positional relationship.

Accordingly, variety of devices for magnetic treatment increases very quickly (especially, after rise in the cost of oil during the seventies of XX century). Thus, detail survey of scientific publications and patent specifications in this subject-matter is impossible here in principle, and only main kinds of magnetic systems for treatment of fluid media considered below.

Some inventors are believed that magnetic field intensity is principal factor of efficiency of magnetic treatment of fluid media. Evidently, that high level and easy regulation of this parameter in wide range depend on viscosity and head pressure of fluid media can be provided using electromagnets (see, for example, US 2009/0325109 A1 ).

Unfortunately, these devices are uneconomical because energy yield provided by completeness of combustion of magnetically-treated (especially, gas) fuel is the less, the greater expenditure of electricity for feed of electromagnets. Moreover, they are cumbersome and, therefore, practically unsuitable in fuel channels of internal-combustion engines of transport vehicles.

It is necessary to keep in mind too, that effect of magnetic treatment subsides appreciably about in an hour and a half, and then progressively peters out. Therefore fluid media must be treated with magnetic field, as a rule, before consumption of theirs.

This condition can be accomplished with such compact flow-through systems on the basis of permanent magnets, which may incorporate into fuel channels of various consumers of magnetically-treated fluid media [e.g.: 1. Device for magnetic treatment of water and liquid and gaseous fuels (U.S. 4,357,237); 2. Magnetic activator of natural or other fuel gas placed before burners of industrial steam generators (website www.skifcorp.com.ua of Ukrainian corporation «SKIF»; 3. Device for magnetic treatment of gas flowing through a polymeric feed pipeline (UA 44934 U); 4. Fuel filter of an internal-combustion engine equipped with a set of permanent magnets (RU 2196918 C1 ) etc.].

For the purpose of minimization of radial dimensions, permanent magnets are usually placed along stream of fluid media inside and/or outside of a respective (usually non- ferromagnetic) pipeline.

UA 59679 A discloses an exotic method for magnetic treatment of liquid or gas, which provides allegedly resonant anisotropic action of magnetic field on treated substances.

A device for realization of this method comprises of a few (usually no less than three) plate-type permanent magnets oriented in series along stream of fluid medium. They must be placed angularly within a round in cross-section case, and required angles must be equal to angles between adjacent interatomic covalent bonds in molecule of selected substance (e.g. 104°27' for water, 09°28' for methane, 119°54' for ethylene, 120° for benzene, 106°47' for ammonia etc.).

In the judgment of the inventors, crossing of several magnetic fluxes at these angles provides the most effective treatment of gaseous or liquid substances. However, any such device can be effective only under condition that it is intended for magnetic treatment of a specified practically pure chemical compound whereas majority of fluid media are mixtures of at least two chemical compounds.

In fact, water from any natural surface or underground source comprising various dissolved and mechanical impurities, well head gas, shale gas, products of in-situ coal gasification, synthetic gas, petroleum products such as gasolines and diesel fuels, gasohol etc. are typical examples of multicomponent mixtures.

Accordingly, it is necessary to have devices suitable for effective magnetic treatment of gaseous and liquid fluid media of various chemical compositions. Such devices must provide in gaps between permanent magnets maximally big value of magnetic induction.

The US 2007/0138077 A1 discloses a flow-through magnetic cell and a few based on these cells devices for magnetic treatment of fluid media. They are the most closest to the proposed further magnetic cell and devices.

The known flow-through magnetic cell (see Figs 21 and 22, positions 10, 11 , 12, 13 and 22) has placed with a uniform gap no more than 90 mm (but preferably 60 mm or less) external and internal replaceable magnetic units (10) and (11 ). Each such unit (named originally «cartridge») comprises of at least two identical long plate-type permanent magnets attached one to another by their flat side faces. Space between said units (10) and (11 ) is separated by an arc-like partition (12) on an air cave and a channel (13) for pass of fluid medium. This partition (12) is usually a part of a wall of a non-ferromagnetic conduit (22) incorporated into basic channel for supply of fluid medium from its source to a consumer. In operative position, the interface surfaces of magnets in said units have oriented across of fluid medium stream. Fig.23 shows compound plate-type permanent magnets (28), (29) and (30) fixed by non-magnetic guides (32) within said units (10) and (11 ). The magnets can be selected from group comprising sintered ferrites, magnets on the basis of rare-earth elements (especially, sintered composite Nd-Fe-B), and magnets on the basis of nickel (especially, Al-Ni-Co).

In the judgment of the inventors, quantity of the magnets within said units can change depend on ratio of diameter of said conduit (22) to the length of such its part, where said magnets are placed. Unfortunately, the inventors do not give explicit and exact instructions with respect to positional relationship of magnets' poles within the known magnetic cell. Specification of claimed invention comprises of only vague allusions regarding possibility to change above-mentioned positional relationship depend on type and discharge of fuel, temperature and pressure of fuel during its magnetic treatment, space of time between magnetic treatment and combustion of magnetically-treated fuel, and above-mentioned ratio of diameter and length. It is indistinctly advised too, that magnetic fields creating by said permanent magnets must be oriented to the fuel stream at respective angles.

The simplest known device for magnetic treatment of fluid media showed on Fig.22 has two above-described flow-through magnetic cells and joint case in the form of said conduit (22). Said magnetic units (10) are mounted individually on top and below of this conduit (22) and two magnetic units (11 ) are mounted on both sides of a separating plate (27) made from ferritic or electric steel and rigidly fixed in diametral plane of the conduit (22) between the channels (13) for pass of fluid medium.

Each complex device for magnetic treatment of fluid media comprises of an input flange, a diffuser, a dispenser, at least two concentrically arranged above-described simple devices, a collector of magnetically-treated fluid medium, a confuser, and an output flange. These flanges provide insertion of said complex device into a fuel channel of a consumer.

According to the said US 2007/0138077 A1 data, magnetic induction in the gap of each known magnetic cell is in the range from 0.02 to 1.0 T.

The known magnetic cell is cumbersome owing to assembling with the conduit. Accordingly, known devices for magnetic treatment of fluid media on the basis of such cells have large diameters. However, main disadvantage consists in that each aforesaid part of the conduit, which is placed between each pair of magnetic units (10) and (11 ), does not minimize a gap between opposite magnets and, thereby, excludes possibility of increase of magnetic induction in the gap up to practically gainable limit. This decreases efficiency of magnetic treatment of fluid media by the devices based on said known magnetic cell.

Summary of the Invention

The invention is based on the problem, by way of improvement of positional relationship of permanent magnets and matching of their magnetic fields, to create a more compact flow-through magnetic cell permitting substantial gain of magnetic induction in a gap and based on this cell more effective devices for magnetic treatment of fluid media. First part of this problem has solved in that in a flow-through magnetic cell having two placed with an uniform gap magnetic units, each of which comprises of at least two identical plate-type permanent magnets attached one to another by their flat side faces, and a suitable holder of these units in operative position, according to the invention the magnets within each magnetic unit are arranged in alternate polarity and connected on the outer in respect of said gap sides by a magnetic conductor, interface surfaces between these magnets oriented, in operative position, along of fluid medium stream, the opposite magnets of the different magnetic units directed one to another by identical magnetic poles, and said holder of the magnetic units is located beyond said gap.

In this flow-through magnetic cell the gap between opposite magnetic units is empty.

Therefore, said units can be placed as near as permissible depend on viscosity and head pressure of fluid medium. Said magnetic conductors decrease losses of magnetic fluxes in space, and intercoupling of these fluxes provide crowding of magnetic field lines in the central zone of the gap between said identical magnetic units.

As a results, magnetic induction in the gap increases substantially (up to 1.4 T and more). Accordingly, it intensifies magnetic treatment of fluid media.

First additional feature consists in that each magnetic unit has two said permanent magnets, and the gap between said units is no more than 30% of the magnet plate thickness. This provides effective magnetic treatment of any gaseous and liquid fluid media.

Second additional feature consists in that each magnetic unit has three said permanent magnets, and the gap between said units is no more than 20% of the magnet plate thickness. This is reasonable for treatment of preferably gaseous fluid media.

Third additional feature consists in that said holder has form of flow-through case, which made at least partially from ferromagnetic material, and these ferromagnetic case's parts adjacent to the each pair of said permanent magnets serve as the magnetic conductors. This provides substantial simplification of fabrication and mounting of the magnetic cells in the time of large-scale production of the simplest devices for magnetic treatment of fluid media.

Second part of aforesaid problem has solved in that in a device comprising a flow- through housing equipped with suitable means for its insertion into a feed channel connecting a source and a consumer of a fluid medium and serves as a holder of at least one flow-through magnetic cell that has two placed with an uniform gap magnetic units, each of which comprises of at least two identical plate-type permanent magnets attached one to another by their flat side faces, according to the invention the magnets within each said magnetic unit of any magnetic cell are arranged in alternate polarity and connected on the outer in respect of said gap sides by a magnetic conductor, interface surfaces between these magnets oriented, in operative position, along of fluid medium stream, and the opposite magnets of the different magnetic units directed one to another by identical magnetic poles. Simple devices of this kind having one magnetic cell are suitable preferably for magnetic treatment of fluid media such as tap water (e.g., before its pouring into home clothes washer), and natural gas or propane-butane mixture (e.g., before combustion by means of gas-stove burners). More complicated devices of this kind having two or more magnetic cells are suitable for treatment of any fluid media in the wide range of flow rates.

First additional feature consists in that the inlet part of said flow-through housing is equipped with a suitable non-ferromagnetic turbulator of fluid medium stream. This provides practically identical magnetic treatment of all fluid medium mass.

Second additional feature consists in that the flow-through housing is equipped with at least two arranged in series magnetic cells and symmetry plane of each next in turn cell is rotated with respect to symmetry planes of the antecedent cell at practically right angle. Overall dimensions of these devices are usually no more than 100...150 mm along axis and 30...50 mm over. This allows easy insert any such device into present fuel channel of any internal-combustion engine. It has been found experimentally that at least two magnetic cells arranged in this manner provide high-performance magnetic treatment of motor fuels.

Third additional feature consists in that the flow-through housing is equipped with at least one matrix, which comprises of in each horizontal row and in each vertical column no less than two identical magnetic cells mounted in joint magnetic conductor, and which dams an opening of the flow-through housing. This allows to treat intensive streams of fluid media, e.g., for feed of high-power gas boilers or industrial steam generators.

Fourth additional feature consists in that the flow-through housing is equipped with at least two arranged in series matrices and symmetry planes of the magnetic cells in each next in turn matrix is rotated with respect to symmetry planes of the magnetic cells in the antecedent matrix at practically right angle. This provides intensive turbulization of fluid media stream without additional turbulators and maximal efficiency of magnetic treatment.

Best Embodiments of the Invention

A simplest flow^through magnetic cell (see Fig.1 ) has two placed with an uniform gap non-designated especially magnetic units, each of which comprises of identical plate-type permanent magnets attached one to another by their flat side faces.

The magnets 1 , 2 of upper magnetic unit and the magnets 3, 4 of lower magnetic unit are arranged in alternate N-S polarity and connected on the outer in respect of said gap sides by magnetic conductors 5. The opposite magnets 1 , 4 and 2, 3 of the different opposite magnetic units are directed one to another by identical magnetic poles. Interface surfaces between the magnets 1 , 2 and 3, 4 are found practically in one plane and oriented, in operative position, along of fluid medium stream. Above-mentioned magnetic units are fixed, in operative position, to a holder 6 that is located beyond said gap. This holder 6 showed here symbolically by dashed line.

If each above-mentioned magnetic unit has only two magnets, as it is shown on the Fig.1 , the gap Z between these units is no more than 30% of the magnet plate thickness δ.

Fig.3 shows a flow-through magnetic cell, in which each above-mentioned magnetic unit comprises of three non-designated especially identical plate-type permanent magnets attached one to another by their flat side faces. In such cases, the gap Z between said magnetic units is no more than 20% of the magnet plate thickness δ.

Devices for magnetic treatment of fluid media may have at least one flow-through magnetic cell, but, as a rule, two or more such cells and various structures depend on required full-capacity discharge.

So, Fig.4 shows a typical small-envelope device having two tandem magnetic cells 7. It has a compound (preferably round in cross-section) at least partially ferromagnetic case including, for instance, a ferromagnetic tube 8 that serves simultaneously as aforesaid holder "6" of the magnetic cells 7 and as joint magnetic conductor "5" for all adjacent magnet units. The cells 7 are separated by a non-ferromagnetic spacer 9 made from preferably metallic material, e.g., electrical copper or a copper-based alloy such as brass or bronze.

It is desirable to arrange two or more magnetic cells 7 in this way that symmetry plane of each next in turn cell 7 is rotated with respect to symmetry plane of the antecedent cell 7 at practically right angle, as it is shown on the Fig.4.

The tube 8 is equipped by inlet and outlet end elements, e.g. by coupling nuts 10 having union nipples 1 1 for connection to non-showed here hosepipes for supply of fresh fluid medium to magnetic treatment and removal of magnetically-treated fluid medium. It is clear, that socket joints, flanges and other suitable connectors can be used instead said coupling nuts 10 depend on a respective fuel (or water) channel structure.

Side faces of non-designated here magnets of each magnetic cells 7, which are directed to the round ferromagnetic tube 8, can be rounded. This simplifies mounting of magnetic cells 7 within the tube 8 (which serves as above-mentioned joint magnetic conductor), and excludes requirement in ring-like ferromagnetic inserts.

It is desirable to arrange a suitable non-ferromagnetic turbulator 12 before the single (or first in streamwise series) magnetic cell 7. It is shown on the Fig.4 as a holed base one of two cups 13, which are used for fixation of the magnetic cells 7 within the tube 8 (in particular, together with thrust washers 14, if it is required).

It is reasonable to use a cast flow-through housing 15 equipped with flanges 16 as a base of devices for magnetic treatment having high throughput (i.e. more than a few tens of liters of water or liquid fuel per hour and more than 100 m³ of gas per hour), and to equip this housing 15 by at least one matrix 17 comprising in each horizontal row and in each vertical column no less than two identical magnetic cells 7 (Figs 5 and 6).

The magnetic cells 7 of any matrix 17 are mounted within through-holes of a ferromagnetic lattice 18 that serves as joint magnetic conductor for all magnetic units. Each matrix 17 (as such or together with non-showed especially sealing fixtures) must dam opening of the case 15. If at least two matrices 17 are placed one after another within the housing 15, they must be separated by non-designated especially thin spacer(s) made from above-mentioned non-ferromagnetic material.

The magnetic cells 7 can be arranged within said lattice 18 in this way that their symmetry planes coincide and are parallel within horizontal rows or vertical columns. However, if the housing 15 is equipped with one matrix 17, it is desirable to arrange adjoining magnetic cells 7 in this way that their symmetry planes would have crossed at practically right angle, as it shown on the Fig.6. Similarly, if the housing 15 is equipped with two or more matrices 17, symmetry planes of the magnetic cells 7 in each next in turn matrix 17 is rotated with respect to symmetry planes of the magnetic cells 7 in the antecedent matrix 17 at practically right angle. This increase efficiency of magnetic treatment and excludes requirement in any additional turbulators of any fluid medium.

It is clear for each person skilled in the art that showed and described embodiments are not ruled out various additions and elaborations based on common engineering knowledge and that scope of rights is limited only by appended claims. In particular,

The matrices 17 may be cross-shaped or rounded in front view;

Said devices in toto may be equipped by security facilities for prevention of unauthorized access to the magnetic cells;

Said permanent magnets may have various chemical compositions comprising iron, nickel, cobalt, neodymium, boron, praseodymium, samarium, gadolinium, , terbium, dysprosium and other ferromagnetic chemical elements used in various combination and proportions;

The magnets' surfaces contacting with such fluid media, which include abrasive or corrosive ingredients, may have non-ferromagnetic anti-wear and/or anticorrosive coatings made from suitable polymers (e.g., polypropylene, polycarbonate, polytetrafluorethylene), metals (e.g., zinc, cadmium or chromium) and alloys on the basis of said metals.

It is obvious that such coatings must be deposited at temperature below Curie point, e.g., by spraying of polymeric powders using stream of heated technologically inert gas (usually nitrogen and, seldom, argon) or by low-temperature electrodeposition of metals.

It is desirable to select such ranges of ratios of overall dimensions of the used magnets: height to length - from 1 to (3÷5), height to width - from 1 to (1.3÷2) and width to length - from 1 to (1.5*1.7). The gap between the magnetic units within magnetic cells must be no less than 0.7 mm, and preferably no less than 1.0 mm.

The Fig.2 shows typical patterns of magnetic fluxes within the magnetic cells according to the Fig.1.

Firstly, two pairs of opposite magnetic poles (namely S and N poles of the magnets 1 and 2 of upper magnetic unit and N and S poles of the magnets 3 and 4 of lower magnetic unit) interact via magnetic conductors 5. Accordingly, respective parts of magnetic fluxes are closed, and exit their lines of force outside magnetic cell is practically excluded.

Secondly, within the gap between the upper and lower magnetic units:

A part of lines of force between poles N-S of adjacent magnets 1 and 2 of upper unit and poles S-N of adjacent magnets 3 and 4 of lower unit tends to closure inside the gap;

Other part of lines of force between different magnetic poles N-S and S-N of the diagonally arranged magnets 1 ,3 and 2,4 causes mutual attraction of said magnetic units, and

Another part of lines of force between identical magnetic poles N-N and S-S of the opposite magnets 1.4 and 2.3 causes mutual repulsion of said magnetic units.

Owing to interaction of all lines of force between said magnetic units within said magnetic cell spring up: in the gap's middle - a zone , where magnetic induction is maximal, two zones O on the left and on the right of zone M, where magnetic induction is practically equal to zero, and two zones K along the gap's edges, where magnetic induction has intermediate values.

An experimental magnetic cell composed of two pairs of permanent magnets Nd-Fe-B having 30 mm length, 20 mm width and 10 mm height was produced and tested. It was found that magnetic induction in the zone of the gap between magnetic units can exceed 1.4 T if said gap is less than 3 mm, and 1.7 T if said gap is less than 2 mm.

Accordingly, gradient of magnetic induction between said zones M, O and K is found in the range from 0 to 1700 mT/m that provides high-performance magnetic treatment of fluid media during their pumping through any devices according to the invention.

Turbulization of fluid media stream at inlet into the device according to the Fig.4, or, especially, turbulization owing to rotation of stream while it passes through the arranged in series within the devices according to the Figs 4 and 5 magnetic cells having alternate symmetry planes increases efficiency of magnetic treatment additionally. Multiple tests affirmed this fact. Results of one such test given below (see Table). They were obtained during comparison testing of the device according to the Fig.5 mounted on a gas water heater. Said device was equipped by two matrices 17, and each matrix 17 had included 64 magnetic cells 7.
