Description

DK 158506BDK 158506B

Den foreliggende opfindelse angår et apparat til magnetisk behandling af vand eller lignende væsker, organiske eller uorganiske forbindelser eller blandinger, med det formål at forhindre, at udskilte materialer, såsom kalk eller kedelsten hæfter sig på beholdervægge.The present invention relates to an apparatus for the magnetic treatment of water or similar liquids, organic or inorganic compounds or mixtures, for the purpose of preventing separated materials such as lime or scales from adhering to container walls.

5 Opfindelsen er rettet på en videre udvikling af det i DD-A-138717 beskrevne apparat, som omfatter et rørformet hus, der er anbragt koaksialt omkring det rør eller rørstykke, hvorigennem væsken, som skal behandles, strømmer.The invention is directed to a further development of the apparatus disclosed in DD-A-138717, which comprises a tubular housing coaxially disposed about the tube or tube through which the liquid to be treated flows.

Røret består af PVC, og inde i røret findes jernkerner og ^ derimellem lejrede skiveformede afstandsstykker med i deres overflader anbragte noter. Udenom røret er anbragt elektromagnetiske spoler, der sammen med jernkernerne frembringer flere magnetiske felter med modsat polretninger inde i rørstykket.The pipe is made of PVC, and inside the pipe there are iron cores and interspersed disc-shaped spacers with grooves placed in their surfaces. Outside the tube are electromagnetic coils which together with the iron cores produce several magnetic fields with opposite pole directions inside the tube.

En ulempe ved dette kendte apparat er, at det på grund af konstruktionsudformningen kun lader sig på- og afmontere med stort besvær, ligesom vedligeholdelsen er kompliceret . Endvidere opnås kun en ringe virkningsgrad af 20 magnetfeltet.A disadvantage of this known apparatus is that due to the design design it can only be mounted and dismounted with great hassle, and the maintenance is complicated. Furthermore, only a small efficiency of the magnetic field is obtained.

For at udnytte den fordelagtige egenskab ved det magnetiske felt er der udviklet flere fremgangsmåder og apparater, hvormed man kan forhindre fremkomsten og nr aflejringen af kalk og kedelsten eller andre skadelige materialer på væggen af vandbeholdere, kedler, rørledninger og lignende.To take advantage of the advantageous properties of the magnetic field, several methods and apparatus have been developed to prevent the appearance and deposition of lime and scales or other harmful materials on the walls of water tanks, boilers, pipelines and the like.

Fra HU-PS 91 278 kendes en sådan fremgangsmåde. Materia-30 leaflejringen på metaloverfladen forhindres i dette tilfælde ved at forstyrre krystaldannelsen derved, at væggene og krystallerne underkastes en magnetisk påvirkning, samtidig med, at der ledes en elektrisk strøm gennem beholderen.Such a method is known from HU-PS 91 278. In this case, the material leaf deposition on the metal surface is prevented by interfering with the crystal formation by subjecting the walls and crystals to a magnetic influence while conducting an electric current through the container.

En lignende løsning kendes fra AT-PS 191 810, hvorved man for at opnå en tilsvarende effekt anvender et specielt magnet system. Endnu et trin i udviklingen er nævnt i HUPS 162 455. Ifølge den herfra kendte opfindelse benyttes 5 et trefaset magnetisk drejefelt.A similar solution is known from AT-PS 191 810, whereby a special magnetic system is used to obtain a corresponding effect. Another step in the development is mentioned in HUPS 162 455. According to the present invention, a three-phase magnetic turning field is used.

Den skadelige virkning af kedelstensaflejringer gør sig især gældende i dampkraftværker. For at eliminere denne har man udarbejdet mange forskellige løsninger. Således 10 kendes fra GB-PS 1 291 600 en fremgangsmåde, hvorved der anvendes et magnetisk felt til at fjerne FeøO^ og F^O^ fra fødevandet.The detrimental effect of scaling deposits is particularly evident in steam power plants. To eliminate this, many different solutions have been devised. Thus, from GB-PS 1,291,600, a method is used which uses a magnetic field to remove FeOO and FOO from the feed water.

For at forhindre aflejring af skadelige materialer, som 15 udskilles af vand og andre væsker, har man ligeledes angivet talrige løsninger. Til disse hører forskellige med permanentmagneter udstyrede indretninger, der drives af roterende skovlhjul.In order to prevent the deposition of harmful materials, which are excreted by water and other liquids, numerous solutions have also been provided. These include various permanent-magnet devices, which are driven by rotating impeller.

20 Fælles kendetegn for de nævnte indretninger er de fælles ulemper, som består deri, at magnetiseringen sker med symmetriske magneter. Indretninger eller apparater af denne art har derfor kun vist sig anvendelige i særlige tilfælde.Common characteristics of the said devices are the common disadvantages which consist in the fact that the magnetization occurs with symmetrical magnets. Devices or apparatus of this kind have therefore only proved useful in special cases.

For at eliminere ulemperne ved de kendte tekniske løsninger er der foreslået flere foranstaltninger. Dertil hører en opfindelse, som er angivet i HU-PS 173 113, ifølge hvilken magnetiseringen gennemføres ved hjælp af 30 asymmetriske magneter.In order to eliminate the disadvantages of the known technical solutions, several measures have been proposed. There is also an invention disclosed in HU-PS 173 113, according to which the magnetization is carried out by means of 30 asymmetric magnets.

Ulempen herved er, at feltstyrken ved det anvendte magnetsystem er begrænset, samt at strømningshastigheden og strømmens retning er begrænset, ligesom virkningsgraden 35 er meget lille.The disadvantage of this is that the field strength of the magnetic system used is limited, and that the flow rate and direction of flow are limited, as is the efficiency 35 very small.

For at forbedre virkningsgraden af det ovennævnte apparat er der opnået patent på en løsning (HU-PS 176 792). Ifølge dette patentskrift udformes magneten vinkelformet med poler. Lysningen til gennemstrømning af væsken tilveje-5 bringes mellem polerne. I polerne findes desuden endnu en central åbning, hvis to ender kan være lukket med en prop (af et paramagnetisk materiale). På denne måde er det muligt at forøge virkningsgraden, men strømningshastigheden kan ikke forøges. Anvendelsesområdet er der-10 for begrænset.In order to improve the efficiency of the above-mentioned apparatus, a solution has been obtained (HU-PS 176 792). According to this patent, the magnet is angularly shaped with poles. The liquid to flow the liquid is provided between the poles. In the poles there is also another central opening, the two ends of which can be closed with a plug (of a paramagnetic material). In this way it is possible to increase the efficiency, but the flow rate cannot be increased. The scope is limited to 10.

Endnu en ulempe ved det netop beskrevne apparat består deri, at strømningsmodstanden på grund af formen er stor.Yet another disadvantage of the apparatus just described is that the flow resistance due to the mold is high.

Inde i apparatet opstår ugunstige turbulente strømninger, 15 og et apparat af denne art kan kun drives under opretholdelse af en bestemt strømningsretning. Som følge deraf kan et sådant apparat ikke anvendes i et recirkulationssystem. Desuden er det ikke eller kun vanskeligt, muligt at adskille og rense et sådant apparat, 20 således at gennemstrømningsevnen - i afhængighed af forureningerne i den gennemstrømmende væske - formindskes. Samtidigt formindskes også apparatets holdbarhed og virkningsgrad.Within the apparatus, adverse turbulent flows occur, and an apparatus of this kind can be operated only while maintaining a particular flow direction. As a result, such an apparatus cannot be used in a recirculation system. Furthermore, it is not, or only difficult, possible to separate and purify such an apparatus, 20 so as to reduce the flow - depending on the contaminants in the flowing fluid -. At the same time, the durability and efficiency of the device are also reduced.

25 Der er tidligere udviklet et apparat til at overvinde disse ulemper. Dette apparat udviser tre magnetiske felter, nemlig et formagnetiseringsfelt, et hovedmagnetiseringsfelt og et eftermagnetiseringsfelt. Anvendelsen af flere magnetiske felter har den fordel, at man ved hjælp 30 af et rør, der samler de centrale magnetiske kraftlinier, kan forbedre strømningsforholdene, således at virkningsgraden bliver væsentlig større, for ikke at tale om apparatets demonterbarhed, hvilket muliggør en hurtig rensning.25 An apparatus has previously been developed to overcome these drawbacks. This apparatus exhibits three magnetic fields, namely, a pre-magnetization field, a main magnetization field, and a post-magnetization field. The use of several magnetic fields has the advantage that by means of a tube which assembles the central magnetic power lines, the flow conditions can be improved, so that the efficiency becomes considerably greater, not to mention the detachability of the apparatus, which allows a quick cleaning.

Dette apparat har imidlertid ikke kunnet opfylde de stigende krav. På den ene side var fremstillingsprisen 35However, this apparatus has not been able to meet the increasing demands. On the one hand, the manufacturing price was 35

DK 158506BDK 158506B

4 for høj, og på den anden side har det været nødvendigt med forskelligt tilbehør eller bestanddele, hvis montage og materialebehov krævede en uddannet fagmand.4 is too high, and on the other hand, different accessories or components have been required, whose assembly and material requirements required a qualified professional.

5 Den foreliggende opfindelse har således til formål at videreudvikle et apparat, som ikke har de ved de kendte apparater forekommende ulemper, som er lettere at på- og afmontere, er mere servicevenligt og sikrer en intensiv virkning af magnetfelterne på væsken.The present invention thus aims to further develop an apparatus which does not have the disadvantages of the known apparatus which are easier to install and remove, is more service-friendly and ensures an intense effect of the magnetic fields on the liquid.

Dette formål opnås med apparatet ifølge opfindelsen, der er ejendommelig ved det i den kendetegnende del af krav 1 anførte.This object is achieved with the apparatus according to the invention, which is characterized by the characterizing part of claim 1.

15 Opfindelsen er baseret på den erkendelse, at virkningen i første række ikke er bestemt af rørledningen, men derimod af væskens strømningshastighed, dvs. den inden for et bestemt tidsrum gennemstrømmende mængde. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16The invention is based on the realization that the effect is primarily not determined by the pipeline, but by the flow rate of the liquid, ie. the quantity flowing within a specified period of time. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

Apparatet ifølge opfindelsen omfatter flere, fortrinsvis 2 fem, med lige store mellemrum monterede, ved afstands 3 ringe adskilte magnetringe, at der mellem magnetringene 4 findes ved afstandsringe understøttede med huller ud 5 styrede afbøjningsorganer, som leder den gennemstrømmende 6 væske mod magnetringene til områder med konstant felt 7 styrke, samt at magnetringene, afstandringene og afbøj 8 ningsorganerne er indesluttet i et af paramagnetisk ma 9 teriale bestående hus, som i begge ender er lukket med 10 flanger til montering i rørledninger.The apparatus according to the invention comprises several, preferably 2, five equally spaced magnetic rings, spaced apart by spacer rings 3, that between the magnet rings 4 are provided by spacer rings supported by holes 5 controlled by deflection means, which guide the flowing 6 liquid towards the magnet rings to areas with constant field 7 strength, and that the magnet rings, spacer rings and deflection members 8 are enclosed in a housing of paramagnetic material 9, which is closed at both ends with 10 flanges for installation in pipelines.

Ifølge en foretrukken udførelsesform for opfindelsen er 13 afstandsringene tætningsringe, og afbøjningsorganerne 14 består af prelskiver, der i afhængighed af strømnings 15 mængden er forsynet med tilsvarende huller. Ifølge denne 16 udførelsesform er der mellem huset og flangerne en udskiftelig, hensigtsmæssig med gevind udstyret samling.According to a preferred embodiment of the invention, the spacer rings 13 are sealing rings and the deflection means 14 consist of baffles which, depending on the flow 15, are provided with corresponding holes. According to this 16 embodiment, there is an interchangeable, conveniently threaded assembly between the housing and the flanges.

Ifølge endnu en hensigtsmæssig udførelsesform for opfindelsen er flangerne, der lukker huset, forsynet med gevind for tilslutning til en rørledning.According to yet another convenient embodiment of the invention, the flanges closing the housing are provided with threads for connection to a pipeline.

5 Opfindelsen skal i det efterfølgende illustreres nærmere med henvisning til tegningen, hvor fig. 1 viser apparatet skematisk og delvis i snit, og 10 fig. 2 viser apparatet udstyret med afbøjningsorganerne.BRIEF DESCRIPTION OF THE DRAWINGS The invention will be illustrated in the following with reference to the drawings, in which: FIG. 1 shows the apparatus schematically and partly in section, and FIG. 2 shows the apparatus equipped with the deflection means.

Ved betragtning af fig. 1 ses, at huset 2 indvendig indeholder afstandsringe 3, magnetringe 4 og derimellem afbøjningsorganer 5. Magnetringene 4 er indbygget med 15 samme indbyrdes afstand, hvorved feltstyrken mellem magnetringene 4 er ens. I dette mellemrum med ens feltstyrke er indført afbøjningsorganerne 5, som er understøttet af afstandsringe 3. Afstandsringene 3 er hensigtsmæssigt tætnings- eller pakningsringe. Afbøjningsorganerne 5 el-20 ler prelskiverne er på deres mellem magnetringene 4 værende dele udstyret med huller 6, hvis diameter er afpasset efter mængden af den gennemstrømmende væske.In view of FIG. 1 it is seen that the housing 2 internally contains spacer rings 3, magnetic rings 4 and in between deflection means 5. The magnet rings 4 are built in with the same spacing, whereby the field strength between the magnet rings 4 is equal. Into this space of equal field strength are introduced the deflection means 5, which are supported by spacer rings 3. The spacer rings 3 are suitably sealing or packing rings. The deflection members 5 or 20 of the baffle discs are provided with holes 6 of their diameter between the magnet rings 4, the diameter of which is adapted to the amount of the flowing liquid.

Huset 2 er udført af et paramagnetisk materiale og er lukket i begge ender med en kappe eller flange 1, der ved 25 hjælp af en gevindsamling er tilsluttet huset 2. Enden af kappen 1 er forsynet med en flange eller gevind. Det er hensigtsmæssigt, at samlingen af kappen 1 og rørledningen sker med en hollænder.The housing 2 is made of a paramagnetic material and is closed at both ends with a sheath or flange 1, which is connected to the housing by means of a threaded assembly 2. The end of the sheath 1 is provided with a flange or thread. It is convenient that the assembly of the casing 1 and the pipeline be done with a Dutch bar.

30 Det omhandlede apparat drives på følgende måde: Når apparatet monteres i en rørledning, strømmer væsken i den forudbestemte strømningsretning gennem kappen 1 ind i hulrummet. Strømningsretningen er angivet ved en pil 7.The apparatus in question is operated as follows: When the apparatus is mounted in a pipeline, the liquid flows in the predetermined flow direction through the casing 1 into the cavity. The direction of flow is indicated by an arrow 7.

35 Væsken strømmer gennem den første permanentmagnet 4 og når videre til det første, i strømningsretningen liggende afbøjningsorgan 5, gennem hvis huller 6 væsken kan tvin- 6The liquid flows through the first permanent magnet 4 and reaches the first deflection member 5 in the direction of flow, through whose holes 6 the liquid can be forced 6

ges ind til det centrale hul af den næste magnetring; dette forløb gentages ved den næste magnetring 4 og afbøjningsorganet 5.is given in to the central hole of the next magnetic ring; this process is repeated at the next magnetic ring 4 and the deflection member 5.

5 Gennemstrømningsevnen og en til strømningshastigheden hørende passende feltstyrke er bestemt af afstanden mellem magnetringen 4 og tykkelsen af afstandsringen 3.5 The flowability and a flow rate appropriate to the flow rate are determined by the distance between the magnet ring 4 and the thickness of the spacer ring 3.

I fig. 2 ses udformningen af det i apparatet forekommende 10 afbøjningsorgan 5 eller prelskiven med hullerne 6.In FIG. 2, the design of the deflection member 5 or the baffle with holes 6 is shown in the apparatus.

Det omhandlede apparat har den fordel, at de enkelte dele let kan udskiftes. Apparatet kan indbygges i et vilkårligt system, f.eks. i et varmeanlæg med cirkulerende 15 vand, og drives i forbindelse hermed.The apparatus in question has the advantage that the individual parts can be easily replaced. The device can be built into any system, e.g. in a heating system with circulating water, and is operated in connection therewith.
