Description
Erfindung betrifft eine Trennvorrichtung in Form eines Rohrspaltfilters für das Abtrennen (Filtern) von stark schleißenden Feststoffen gemäß der Gattung der Patentansprüche.The invention relates to a separation device in the form of a tube gap filter for the separation (filtering) of highly abrasive solids according to the preamble of the claims.
Ein Filter hält, wie ein Sieb, Feststoffe aus einem Gas- oder Flüssigkeitsstrom zurück. Die feststofffreie Phase wird bei der Filtration von Flüssigkeiten mit Filtrat und in der Gasfiltration meist mit Reingas bezeichnet. An der Oberfläche des Filters zurückbleibender Feststoff heißt Filterkuchen, die Filtration findet jedoch insbesondere in der Gasphase je nach Aufbau des Filters auch oder ausschließlich in dessen Innerem statt, so dass nicht in jedem Fall ein Filterkuchen entsteht.A filter, like a sieve, retains solids from a gas or liquid stream. The solids-free phase is usually referred to in the filtration of liquids with filtrate and in gas filtration with clean gas. Depending on the design of the filter, the filtration also takes place, especially in the gas phase, also or exclusively in its interior, so that a filter cake is not produced in each case.
Die treibende Kraft einer Filtration ist eine Druckdifferenz des Transportmediums vor und nach dem Filter. Das Medium wird entweder durch den Filter gesaugt oder durch Überdruck durch den Filter gepresst. Man unterscheidet dabei Tiefen-, Querstrom- und Kuchenfiltration.The driving force of a filtration is a pressure difference of the transport medium before and after the filter. The medium is either sucked through the filter or pressed through the filter by overpressure. A distinction is made between deep, cross-flow and cake filtration.
Bei der Kuchenfiltration bildet sich auf dem Filtermedium ein Filterkuchen mit wachsender Dicke, der selbst wiederum als immer dichter werdendes Filtermedium wirkt. Der Filterkuchen muss regelmäßig abgetragen werden. Man erhält sowohl den Feststoff als auch das gereinigte Trägermedium.In the cake filtration forms on the filter medium, a filter cake with increasing thickness, which in turn acts as an increasingly dense filter medium. The filter cake must be removed regularly. Both the solid and the purified carrier medium are obtained.

Das Abtrennen (Filtern) von stark schleißenden Feststoffen aus Suspensionen und Feststoff-haltigen Gasen ist oft ein großes Problem, weil einfache Verfahren, wie bspw. Absieben die Siebe verstopfen bzw. sehr schnell verschleißen, und andere Aggregate, wie bspw. Zyklone schnell verschleißen und sehr kostenintensiv sind, oder andere Verfahren wie das Zentrifugieren zu unproduktiv und zu uneffektiv sind.The separation (filtering) of highly abrasive solids from suspensions and solid-containing gases is often a major problem, because simple processes such as sieving clog the sieves or wear very quickly, and other aggregates, such as. Cyclones wear out quickly and are very costly, or other processes such as centrifuging are too unproductive and too ineffective.
Andererseits wird oft aus oben genenannten Gründen auf das Abtrennen grober Partikel verzichtet und es kommt in hydraulischen und pneumatischen Anlagen zu verheerenden Folgen infolge übergroßer Partikel oder anderer Bruchstücke aus vorgelagerten Anlagenkomponenten.On the other hand, the separation of coarse particles is often omitted for reasons mentioned above and it comes in hydraulic and pneumatic plants to devastating consequences due to oversized particles or other fragments of upstream plant components.
Die Aufgabe der Erfindung besteht darin, ausgehend vom zuvor stehend genannten Stand der Technik eine einfache aber wirkungsvolle Trennvorrichtung/Trennverfahren, die die oben beschriebenen Gefahren abwenden und eine effektivere Durchführung verschiedener technologischer Schritte verwirklichen lassen.The object of the invention is, starting from the above-mentioned prior art, a simple but effective separator / separation methods, which avert the dangers described above and realize a more effective implementation of various technological steps.
Gelöst wird diese Aufgabe durch eine Trennvorrichtung gemäß dem ersten Patentanspruch. Vorteilhafte Ausgestaltungen der Erfindung sind in den nachgeordneten abhängigen Ansprüchen aufgeführt.This object is achieved by a separating device according to the first claim. Advantageous embodiments of the invention are set forth in the subordinate dependent claims.
Die erfindungsgemäße Trennvorrichtung umfasst keramische Platten, die von einem Rohr umgeben sind und so einen Filter ausbilden, der geeignet ist, aus im Allgemeinen sehr feinen Suspensionen und Feststoff-beladenen Gasen Grobpartikel abzusondern.The separating device according to the invention comprises ceramic plates which are surrounded by a tube and thus form a filter which is suitable for separating coarse particles from generally very fine suspensions and solids-laden gases.
Wesentlich dabei ist, dass die Keramikplatten geschliffen sind, d. h. eine glatte Oberfläche aufweisen.It is essential that the ceramic plates are ground, d. H. have a smooth surface.
Vorteilhaft ist dabei, dass die Keramikplatten so angeordnet sind, dass alle Spalte zwischen den Keramikplatten an der Innenkante (Eintrittseite des Rohrspaltfilters im bestimmungsgemäßen Betriebszustand) schmal, gleich breit sind und nach außen (Austrittseite des Rohrspaltfilters im bestimmungsgemäßen Betriebszustand) breiter werden. Durch diese Anordnung der Keramikplatten kann sich kein Feststoff in den Spalten zwischen den Keramikplatten verklemmen.It is advantageous that the ceramic plates are arranged so that all gaps between the ceramic plates on the inner edge (inlet side of the pipe gap filter in the intended operating condition) are narrow, the same width and to the outside (outlet side of the pipe gap filter in the intended operating condition) wider. By this arrangement of the ceramic plates, no solid can jam in the gaps between the ceramic plates.
Die Partikel, die zu groß sind, um durch die Spalten hindurch zu gehen, werden durch den Rohrspaltfilters an seiner Eintrittseite in ein nachgeschaltetes Rohrstück geschoben und bilden den Grobschmutz aus. Dieser Grobschmutz muss von Zeit zu Zeit aus dem nachgeschalteten Rohrstück abgelassen werden.The particles that are too large to pass through the gaps are pushed through the pipe gap filter on its inlet side into a downstream pipe section and form the coarse dirt. This coarse dirt must be drained from the downstream pipe section from time to time.
Das Vorhandensein von Grobpartikeln kann bspw. über ein Schauglas im Rohrstück oder mittels Differenzdruckmessung kontrolliert werden.The presence of coarse particles can be controlled, for example, via a sight glass in the pipe section or by means of differential pressure measurement.
Die erfindungsgemäße Trennvorrichtung (der Filter) dient vor allem als „Sicherung” vor zu groben Partikeln, die im Regelfall nicht, aber bei seltenen Havarie- oder anderen Störfällen auftreten können und dabei zu enormen Schäden in den Anlagen führen.The separation device according to the invention (the filter) is mainly used as a "backup" against coarse particles that usually can not occur but in rare accidents or other incidents and thereby lead to enormous damage in the systems.
Beim Betrieb eines Filters muss damit gerechnet werden, dass sich Bereiche der Filterfläche zeitweise zusetzen und es an den freien Stellen zu Überhöhung der Fließgeschwindigkeit kommt, was bei Metallen und Kunststoffen zwangsläufig zu Verschleißerscheinungen führt. Durch den erfindungsgemäßen Einsatz von Keramik an diesen kritischen Stellen, kann der Verschleiß verhindert bzw. stark minimiert werden.When operating a filter, it is to be expected that areas of the filter surface will temporarily become clogged and that the flow rate will increase at the free points, which inevitably leads to signs of wear on metals and plastics. The inventive use of ceramic at these critical points, the wear can be prevented or greatly minimized.
