Description

"Verrichtung zur Verhütung von Kesselsteinansatz und Korrosionen." Die Erfindung betrifft eine Verrichtung zur Verhütung von Kessel- steinansatz und Kerresionen in Anlagen, welche strömendes oder stehendes Wasser enthalten, mit einem von in die Anlage einzuspei- senden Wasser durchflossenen zylindrischen Gefäß und einer elek- trischen Einrichtung zur Erzeugung eines Stromes im Wasser. "Performs to prevent scale build-up and corrosion." The invention relates to a device for preventing scale deposits and kerresions in systems which contain flowing or stagnant water, with a cylindrical vessel through which water to be injected into the system flows and an electrical device for generating a current in the water.

Zur Verhütung von Kosselsteinansatz und Kerrosionen ist neben den für kleinere Wasserengen wirksamen, mit nagnstestatischen Feldern arbeitenden Cepi-Cowov-Verfahren das für größere Wassermengen wirk- same Copi-VE-Verfahren bekannt geworden, das mit elektromagnetischen Feldern arbeitet. Bei diesem Verfahren kommt ein Durchflußgefäß zur Verwendung, dessen Mantel durch voneinander isolierte Magnet- pole abwechselnder Polarität gebildet wird, die ein Polygon bil- den, ähnlich wie der Steter bei einem Dynamo. Die Magnete sind elektrisch erregt, um die erforderliche Feldstärke fUr größere Wasserengen zu erhalten. To prevent Kosselsteinansatz and Kerrosionen working with nagnstestatischen fields in addition to the effective for smaller water Engen, Cepi-Cowov method, the effective same for larger amounts of water Copi-VE process became known that uses electromagnetic fields. In this process, a flow-through vessel is used, the jacket of which is formed by mutually insulated magnetic poles of alternating polarity, which form a polygon , similar to the constant in a dynamo. The magnets are electrically excited in order to obtain the required field strength for larger amounts of water.

Andererseits ist es zur VerhUtung insbesondere von Kosselsteinansatz in strömendes oder stehendes Wasser enthaltenden Anlagen, nämeich insbesondere zum VerhUten eines Ansetzens von Kesselstein an den Wandungen von äußerlich beheizten Kesseln, bekannt geworden, in diesen selbst an ein Drehstromnetz angeschlossene Elektroden anzuordnen, die in das zu behandelnde Wasser eintauchen. Demgegenier schlägt die Erfindung fUr eine Vorrichtung der eingangs zuerst genannten Art vor, an sich bekannte stabfärige Drehstrom- elektreden in Richtung des Wasserstromes in gleichem Abstand voneinander und parallel sowohl zueinander als auch zur Gefäßwand derart anzuordnen, doß der Abstand jeder Elektrode zur Gefäßwand das fache des Elektrodenabstandes ist. Mit einer diese Merk- male aufweisenden erfindungsgemäßen Vorrichtung zur VerhUtung von Kosselsteinansatz und Kerresionen erreicht man gegenUber den ver- gleichbaren, nach dem Copi-VE-Verfahren mit elektremagnetischen Feldern arbeitenden Vorrichtungen unter Ausnutzung von deren einem Vorteil gegenUber den vormerkten, weiterhin vorbekannten Vor- schlag, in der Speiseleitung angeordnet zu worden, so daß das Wasser bereits vor dem Einspeisen in die Anlage aufbereitet wird, zu- nächst den Vorteil, daß es fertigungstechnisch keine Schwierigkeiten bereitet, Elektroden im Geffeekel wasserdicht und isoliert durchzufUha», während eine wasserdichte EinfUhrung von Magnetpolen wesentlich schwieriger ist. Weiterhin bringt die erfindungsgemäße Vorriehtun@ den Vorteil, daß ihr Elektrodensystem fUr eine vor- gegebene Wassermenge ein wesentlich geringeres Bauvolwen benötigt als Magnete, was im Hinblick darauf von Wichtigkeit ist, daß solche Vorrichtungen oft in bereits bestehende Anlagen eingebaut werden müssen, bei welchen der Platz beschränkt ist ;.och weisen Elek- troden ein wesentlich geringeres Gewicht als Magnete auf, welcher Faktor insbesondere für größere Wossermengen beachtlich ist. Die besondere Anordnung und Ausbildung der Elektroden bringt schließ- lich maximale Ergebnisse in der Verhütung von Kesselsteinansatz und Korrosionen durch die Schaffung eines sehr intensiven Induktions- feldes. On the other hand, it is plants containing the VerhUtung particular Kosselsteinansatz in flowing or stagnant water to arrange nämeich particular for VerhUten a piecing of scale on the walls of externally fired boilers, known, in these self-connected to a three-phase AC electrodes, which is to be treated in the Submerge water. On the other hand , the invention proposes for a device of the type mentioned first to arrange known rod-shaped three-phase electrons in the direction of the water flow at the same distance from one another and parallel to one another as well as to the vessel wall in such a way that the distance between each electrode and the vessel wall does times the distance between the electrodes . With this noticeably male having the inventive device for VerhUtung of Kosselsteinansatz and Kerresionen is achieved against over the comparable, after the COPI VE process with elektremagnetischen fields operating apparatuses utilizing its one advantage over the vormerkten further prior art proposal to have been arranged in the feed line, so that the water is treated before being fed into the system, next to-the advantage that it prepares production engineering no difficulty waterproof electrodes Geffeekel and isolated durchzufUha ", while a water-tight introduction of magnetic poles is much more difficult . Furthermore, bringing the Vorriehtun inventive @ the advantage that their electrode system for a pre-given amount of water a substantially lower Bauvolwen required as magnets, which is in view of importance that such devices must often be installed in existing plants in which the place However , electrodes are much lighter than magnets, which factor is particularly important for larger quantities of water . The special arrangement and design of the electrodes ultimately brings maximum results in the prevention of scale build-up and corrosion by creating a very intensive induction field.

In der beigefügten Zeichnung ist in schematischer Darstellung eine AusfUhrungform der erfindungsgemäßen Vorrichtung veranschaulicht. In dieser bezeichnen 1 und 2 die Anschlußklemmen der Primärwicklung eines Transfornetors T an das Netz. Die Sekundärwicklung dieses Transformators T ist mit drei Anschlußklemmen 3, 4 und 5 versehen, mit welchen stabförmige Elektroden 10, 9 und 11 Uber Durchführungen 6, 7 und 8 verbunden sind, die in dem Deckel eines die Elektroden aufnehmenden Gefäßes 12 elektrisch isolist und druckdicht befestigt sind. Das Gefäß 12 besitzt einen Zuflußstutzen 13 und einen Abfluß- stutzen 14, so daß es von dem einer Anlage einzuspeisenden Wasser durchflossen werden kann, in welcher ein Ansetzen von Kesselstein und Korrosionen mit einer solchen Vorrichtung verhütet werden sollen. Das Gefäß 12 ist bei 15 geerdet und in der Zuleitung zwi- schen der Anschlußklemme 5 und der Durchführung 8 ist schließlich ein Kondensator C von etwa 15 MF angeordnet, um so aus einem Einphasenstrom einen Mehrphasenstrom bzw. elektrisches Drehfeld zu erzeugen. Die Kapazität des Kondensators C ist so zu wählen, daß die Spannungen zwischen den Elektroden 6 und 7 bzw. 7 und8 bzw. 8 und 6 möglichst gleichgroß sind, um zwischen den Strömen zu den Anschlüssen 8, 7 und 6 eine Phosenverschiebung zu erhalten, die in dem Gefäß ein elektrisches Drehfeld entstehen läßt. Selbst- verständlich kann eine solche Umwandlung von einem Einphasenstrom in einen Mehrphasenstrom auch auf andere Art und Weise bewirkt werden. In the accompanying drawing, an embodiment of the device according to the invention is illustrated in a schematic representation. In this, 1 and 2 denote the terminals of the primary winding of a transformer T to the network. The secondary winding of this transformer T is mounted with three terminals 3, 4 and 5 is provided, with which rod-like electrodes 10, 9 and 11 Uber feedthroughs 6, 7 and 8 are connected, the receiving in the lid of the electrodes vessel 12 electrically isolist and pressure-tight manner are. The vessel 12 has an inflow connection 13 and an outflow connection 14, so that the water to be fed into a system can flow through it, in which a build-up of scale and corrosion are to be prevented with such a device. The vessel 12 is grounded at 15 and finally a capacitor C of about 15 MF is arranged in the supply line between the connection terminal 5 and the bushing 8 in order to generate a multiphase current or electrical rotating field from a single-phase current. The capacitance of capacitor C should be chosen so that the voltages between the electrodes 6 and 7 or 7 and 8 or 8 and 6 are equal in size as possible in order to obtain between the currents to the terminals 8, 7 and 6, a Phosenverschiebung that creates a rotating electrical field in the vessel . Of course, such a conversion can be effected by a single phase in a multiphase stream in other ways.

Sind die erkennbar in Richtung des Wasserstromes innerhalb des Ge- fäßes 12 angeordneten stab6cmigen Drehstromelektroden in gleichem Abstand voneinander und parallel sowohl zueinander als auch zur Gefdßwand so angeordnet, daß der Abstand jeder Elektrode zur Ge- fäßwand das fache des Elektrodenabstandes ist, und bildet man die Elektroden als zylindrische Drahtgeflechte aus Silber aus, dann erhält man maximale Ergebnisse in der Verhütung von Kessel- steinansatz und Korrosionen, indem die Elektroden ein sehr inten- sives Induktionsfeld erzeugen, das alle im Wasser gelösten Ionen- Hörtebildner zu beeinflussen vermag. Das Wasser selbst wird bei einer solchen Behandlung chemisch nicht beeinflußt, es behält seine ursprüngliche chemische Beschaffenheit und nimmt weder Ge- ruch noch Geschmack an. Are the rod- shaped three-phase electrodes arranged in the direction of the water flow inside the vessel 12 at the same distance from one another and parallel to one another as well as to the vessel wall so that the distance between each electrode and the vessel wall is the same times the electrode spacing , and if the electrodes are designed as cylindrical wire meshes made of silver, then maximum results are obtained in the prevention of scale deposits and corrosion, as the electrodes generate a very intensive induction field that absorbs all the ions dissolved in the water. Capable of influencing hearing enhancers . The water itself is not chemically influenced by such a treatment, it retains its original chemical composition and takes on neither smell nor taste.
