Antrag auf Eintragung eines Gebrauchsmusters vom 27.11.1995 *25* - Magnetfeidunterstützter Schlammabscheider -Application for registration of a utility model dated 27.11.1995 *25* - Magnetic field assisted sludge separator -
BeschreibungDescription
In der Fernwärme und Heiztechnik sowie in Kühlanlagen werden zum Aushalten disperser Feststoffverunreinigungen aus Wasserkreisläufen bisher Schlammfallen, Schlanmfilter und Schmutzfänger mit magnetischen Einsätzen verwendet. In district heating and heating technology as well as in cooling systems, sludge traps, sludge filters and dirt traps with magnetic inserts are currently used to withstand dispersed solid contamination from water circuits.
Schlammfallen nutzen die Vergrößerung des Stromquerschnittes, um eine Verlängerung der Verweilzeit: des zu reinigenden Wasserstromes im Behälter zu erreichen. Dadurch finden die groben Feststoffteilchen genügend Zeit, um unter Wirkung ihrer Schwerkraft aus dem Wasserstrom auszusedinentieren. Das Verfahren ist nur für grobe Feststoffteilchen wirksam.Sludge traps use the increase in the flow cross-section to extend the residence time of the water flow to be cleaned in the tank. This gives the coarse solid particles enough time to settle out of the water flow under the effect of gravity. The process is only effective for coarse solid particles.
In Schlammfiltern wird eine Verringerung der Feststoffteilchen durch Leiten des zu reinigenden Wasserstromes durch den Siebfilter erreicht. In erster Phase bestimmt die Maschengröße des Filternetzes die zurückgehaltenen Teilchengrößen.Im Laufe des Betriebes, wenn der Siebfilter mit gröberem Schlammanteil festgesetzt wird, werden auch feinere leilchengrößen zurückgehalten.In sludge filters, a reduction in solid particles is achieved by directing the water flow to be cleaned through the sieve filter. In the first phase, the mesh size of the filter net determines the particle sizes retained. During operation, when the sieve filter becomes clogged with coarser sludge, finer particle sizes are also retained.
Gleichzeitig wächst aber der Strömungswiderstand und damit der Druckabfall am Schlanmfilter. Das bewirkt einerseits höheren Energieaufwand der Wasserpumpen, andererseits erzwingt eine erforderliche Filterreinigung einen vermehrten Wartungsaufwand.At the same time, however, the flow resistance and thus the pressure drop at the sludge filter increases. On the one hand, this results in higher energy consumption of the water pumps, and on the other hand, the necessary filter cleaning requires more maintenance.
Schmutzfänger mit magnetischen Einsätzen werden verwendet, um den feinsten Schlamm auszuhalten. Die feinsten Suspensionsteilchen setzen sich in Wasserkreisläufen aus eisenhaltigen Verbindungen zusammen, die meist para- und auch ferromagnetische Eigenschaften aufweisen. An den Magnetpolen der Einsätze werden diese Stoffteilchen angesammelt und nach Erreichen einer bestimmten Agglomerationsmenge durch den Wasserstrom von den Magneten abgerissen. Sie gelangen danach an den Siebfilter, was zur vorerwähnten Beschlagung des Filters führt.Dirt traps with magnetic inserts are used to hold the finest sludge. The finest suspension particles in water circuits are made up of iron-containing compounds, which usually have paramagnetic and ferromagnetic properties. These particles are collected at the magnetic poles of the inserts and, once they have reached a certain agglomeration level, are torn off the magnets by the water flow. They then reach the sieve filter, which leads to the aforementioned fogging of the filter.
Antrag auf Eintragung eines Gebrauchsmusters vom 27.11.1995 *27* - Magnetfeldunterstützter Schlammabscheider -Application for registration of a utility model dated 27.11.1995 *27* - Magnetic field assisted sludge separator -

Der im Schutzanspruch 1 angegebenen Erfindung liegt die Forderung zugrunde einen magnetfeldunterstützten Schlammabscheider (MFSchA) zu schaffen, der die Vorzüge einer Schlanmfalle, sowie die Vorteile eines Feinfilters, der kein Anwachsen der Druckabfallverluste zu folge hat und feinsten paramagnetischen Suspensionen aushält, vereint, dabei aber lange Betriebszeiten zwischen unumgänglichen Innenrevisionen und Reinigungen sichert.The invention specified in claim 1 is based on the requirement to create a magnetic field-assisted sludge separator (MFSchA) that combines the advantages of a sludge trap and the advantages of a fine filter that does not result in an increase in pressure drop losses and can withstand the finest paramagnetic suspensions, while ensuring long operating times between unavoidable internal inspections and cleaning.
Die Forderung wird mit dien im Schutzanspruch 1 aufgeführten Merkmalen gelöst. The requirement is met with the features listed in claim 1.
Im Gegensatz zu bisherigen Konstruktionen vereinigt der MFSchA vier Wirkungsprinzipien mit allen ihren Vorteilen in einem Gerät:In contrast to previous designs, the MFSchA combines four operating principles with all their advantages in one device:
1. Die inertial-sedimentierende Wirkung1. The inertial-sedimenting effect
2. Die Magnetfeldwirkung auf die dispersierten paramagnetischen Teilchen2. The magnetic field effect on the dispersed paramagnetic particles
3. Die Magnetfeldwirkung auf die härtebildenden Wasserbestandteile3. The magnetic field effect on the hardness-forming water components
4. Die rrechanisch reinigende Wirkung eines Siebfilters.4. The chemical cleaning effect of a sieve filter.
Ein Ausführungsbeispiel der Erfindung wird anhand der Figuren 1 und 2 erläutert. Es zeigt:An embodiment of the invention is explained using Figures 1 and 2. It shows:
Fig. 1 ein MFSchA in seiner Arbeitsstellung mit einem Ausschnitt der Seitenwand am Behälter, um die Innenanordnung der Elemente zu zeigen.Fig. 1 an MFSchA in its working position with a cutout of the side wall on the container to show the internal arrangement of the elements.
Fig. 2 den Querschnitt des MFSchA in horizontaler Ebene, der die Flußrichtung des Wassers zwischen den richtungsändernden Schikanen veranschaulicht. Fig. 2 shows the cross-section of the MFSchA in the horizontal plane, illustrating the flow direction of the water between the direction-changing chicanes.
Der suspensionstragende Wasserstrom passiert den Zulaufstutzen (1) und teilt sich symetrisch in zwei Teilströme an den Schikanenplatten (5), der mäanderähnliche Wasserdurchfluß zwischen den Schikanen bewirkt, daß die Wassergeschwindigkeit in den senkrechten Ecken der Schikanenplatten nahe Null ist und die dort infolge der Inertionskraft gelangten größeren Feststoffteilchen langsam zum Bodenblech (6) sedirrentieren können.The suspension-bearing water flow passes the inlet nozzle (1) and splits symmetrically into two partial flows at the chicane plates (5). The meandering water flow between the chicanes means that the water speed in the vertical corners of the chicane plates is close to zero and the larger solid particles that have reached there as a result of the inertion force can slowly settle to the bottom plate (6).

Feinere Teilchen, die vorwiegend aus paramagnetischen Stoffen bestehen, werden an den Polen der Dauermagnete (10) festgehalten und wachsen zu größeren nadeiförmigen Agglomeraten an.Finer particles, which consist mainly of paramagnetic substances, are held at the poles of the permanent magnets (10) and grow into larger needle-shaped agglomerates.
Bei Erreichen einer bestimmten Größe werden sie durch den Wasserstrom von den Magneten abgetrennt und nach dem Sedimsntationsprinzip aus dem Wasserstran ausgeschieden. Nach dem Abtrennen zerfällt das Agglomerat nicht in die ursprüngliche Feindispersion, weil die zu Agglomeraten zusammengeballten Suspensionsteilchen (Eisenverbindungen) ihren Magnetismus beibehalten.When they reach a certain size, they are separated from the magnets by the water flow and separated from the water flow according to the sedimentation principle. After separation, the agglomerate does not break down into the original fine dispersion because the suspension particles (iron compounds) that have been agglomerated into agglomerates retain their magnetism.
Vor den Ablaufstutzen ( 2) ist ein Siebfilter (11) angebracht, um durch Leitungsdruckturbulenzen evtl. mitgerissene Verunreinigungen wirksam aufzuhalten. A sieve filter (11) is installed in front of the drain connection (2) in order to effectively stop any impurities that may be carried along by line pressure turbulence.
Diesem Zweck dient auch der Abstand zwischen der unteren Kante der Schikanenplatten (5) und den Bodenblech (6).The distance between the lower edge of the baffle plates (5) and the floor plate (6) also serves this purpose.
Um das Fortreißen der in. der Bodenschüssel (9)angesammelten Verunreinigungen zu wrhindern, haben die Schikanenbleche (5) einen ausreichend großen Abstand zum Bodenblech (6).In order to prevent the dirt that has accumulated in the base bowl (9) from being carried away, the baffle plates (5) are sufficiently far away from the base plate (6).
Der Schlammablaufstutzen (7) dient zur periodischen Schlammabführung aus dem MFschA, ohne seinen üblichen Betrieb unterbrechen zu müssen.The sludge drain nozzle (7) is used for periodic sludge removal from the MFschA without having to interrupt its normal operation.
Ein zusätzlicher Vorzug des MFSchA besteht darin, daß das magnetische Feld eine physikalische Behandlung der härtebildenden Wasserbestandteile bewirkt. Die Härtebildner verlieren dadurch ihre Eigenschaft,den Kesselstein in festhaftenden, harten Ansatzschichten auszuscheiden. Der Kesselstein kristallisiert an feinsten Kristallisationskeimen die vorwiegend aus eisenhaltigen Korrosionsprodukten bestehen. Dadurch sind Voraussetzungen geschaffen, den Kesselstein im MFSchA als schlammförmige Suspension aus dem Wasserkreislauf auszuhalten.An additional advantage of the MFSchA is that the magnetic field causes a physical treatment of the water components that cause hardness. The hardness-forming substances thereby lose their ability to separate the scale in firmly adhering, hard layers. The scale crystallizes on the finest crystallization nuclei that consist primarily of iron-containing corrosion products. This creates the conditions for the scale to be removed from the water cycle in the MFSchA as a sludge-like suspension.
Um die Innenrevision und Vollreinigung des Gerätes zu erleichtern, sind der Schikaneneinsatz (5) mit den Magneten (10), das Bodenblech (6) sowie der Siebfilter (11) herausnehmbar in dem Behälter des Schlammabscheiders angebracht. To facilitate internal inspection and complete cleaning of the device, the baffle insert (5) with the magnets (10), the base plate (6) and the sieve filter (11) are removably mounted in the container of the sludge separator.
