Description

  

  
 



   Die Erfindung betrifft ein schlauchförmiges Filterelement, das in einem Filterkessel aufgehängt ist.



   Filterschläuche dieser Art sind aus den DT-AS 2 114 226 und 1 917 306 bekannt. Diese Schläuche sind mit verschiedenen Elementen von Innen her abgestützt. Filterschläuche ohne Stützeinsätze hatten sich nicht bewährt, da bei stark verschmutzten Medien und hohen Drücken der   Filterschlauch    zusammengedrückt wurde. Die Stützeinsätze haben zwar eine Verbesserung der Filtrationseigenschaften solcher Filterelemente gebracht, jedoch durch zusätzliches Material und den Einbau desselben eine erhebliche Verteuerung des gesamten Filters verursacht.



   Es wurde nun überraschenderweise gefunden, dass Stützeinsätze, wie sie die DT-AS 2 114 226 beschreibt, nicht erforderlich sind.



   Aufgabe der Erfindung ist es, ein Filterelement zu schaffen, das bei gleicher oder besserer Filtrationsleistung auf die teueren Stützelemente verzichten kann.



   Diese Aufgabe wird durch ein Filterelement für Kesseldruckfilter, bestehend aus einem schlauchförmigen Filtermittel, gelöst und ist dadurch gekennzeichnet, dass der Innenraum des Filtermittels mit losem Füllmaterial beschickt ist.



   Die Erfindung soll anhand von Zeichnungen näher beschrieben werden.



   Darin zeigt:
Fig. 1 einen Vertikalschnitt durch ein Druckfilter mit den erfindungsgemässen Filterelementen,
Fig. 2 den Querschnitt   A-A    durch das Filter der Fig. 1,
Fig. 3a einen verkürzten Vertikalschnitt durch eine Variante des Filters,
Fig. 3b einen Querschnitt B-B durch die Variante der   Fig. 3a.   



   Fig. 4a das Filterelement im Längsschnitt,
Fig. 4b eine Variante des Filterelements.



   In Fig. 1 ist die Anordnung der erfindungsgemässen Filterelemente in einem Filter dargestellt. Im unteren Teil des Kessels 1. dessen Boden auch konisch ausgebildet sein kann, sind Eingang 2 und Rückstand-Ausgang 13 vorgesehen. Der Kessel 1 ist über den Kesselflansch 14 und den Deckelflansch 15 durch den Deckel 5 verschliessbar. Im Deckel 5 ist ein Ringrohr 6 in bekannter Weise befestigt. Das Ringrohr 6 ist mit einem Sammelrohr 7 über ein Rohr 8 verbunden. Das Filterelement 9 ist über den Stutzen 11 und die Befestigung 12 am Sammelrohr 7 angebracht. Der angedeutete Schnitt im oberen Teil des links in der Figur ersichtlichen Filterelements 9 zeigt das Füllmaterial 10.



   In Fig. 2 ist die Anordnung der Sammelrohre 7 zum Ringrohr 6 zu sehen.



   Der untere Teil der Fig. 3a ist mit demjenigen der Fig. 1 gleich. Im oberen Teil ist zwischen dem   Kesselflansch    14 und dem   Deckelflansch    15 eine Trennplatte 16 angebracht, die den Trübraum im unteren Teil des Filters vom Klarraum im oberen Teil des Filters trennt. Die Trennplatte 16 weist Bohrungen 17 auf, deren Anzahl derjenigen der Filterelemente 9 entspricht.



  Die Befestigung des Filterelements 9 erfolgt am Stutzen 11 und einem Befestigungsring 12. Der Entlüftungsstutzen 4 ist unterhalb der Trennplatte 16 vorgesehen.



   Fig. 3b zeigt die beim Schnitt B-B der Fig. 3a sichtbaren runden Öffnungen der Filterelemente 9 und der Austrittsöffnung 3 für das Filtrat.



   Das erfindungsgemässe Filterelement 9 ist in den Fig. 4a und 4b im verkürzten Längsschnitt dargestellt. Das Filtermittel 18 besteht aus einem Gewebe aus Kunststoffen, wie beispielsweise Teflon, Nylon, Perlon oder Naturfasern oder feinen Metallgeweben. Die Maschenweite ist von der Grösse der abzufiltrierenden Feststoffpartikeln abhängig. Das Innere des schlauchförmigen Filters ist mit Füllmaterial 10 ausgefüllt.



  Eine Siebplatte 19 bildet eine Barriere, damit Füllmaterial nicht in den Filtratraum durch den Stutzen 11 treten kann.



   In Fig. 4b ist ein Rohr 20 im Innern des Filterelements 9 angebracht. Hier befindet sich die Siebplatte 19 in der unteren Öffnung des Rohres 20. Die Füllkörper 10 befinden sich im Raum zwischen dem Filtermittel 18 und dem Rohr 20.



   Während der Filtration tritt die Trübe durch den Eingang 2 in den Filterkessel 1 ein. Die Trübe kann mit oder ohne Filterhilfsmittel versehen sein. Durch den Förderdruck wird die Flüssigkeit zum Durchtritt durch das Filtermittel, beispielsweise das Filtergewebe des schlauchförmigen Filterelements 9 gezwungen. Die Feststoffe lagern sich auf der Aussenseite des Filterschlauches ab und werden durch den gegenüber dem Innern des Filterelements 9 herrschenden Überdruck gehalten.



  Das Zusammendrücken des Filterschlauches wird durch die Füllung mit Füllmaterial 10 verhindert. Ein Hinausdrücken des Füllmaterials in den Filtratraum über den Stutzen 11 ist durch die Siebplatte 19 nicht möglich. Das Klarfiltrat wird im Rohr 7 gesammelt und fliesst über das Verbindungsrohr 8 in die Ringleitung 6, um durch den Ausgang 3 das Filter zu verlassen.



   Nach Beendigung eines Filtrationszyklus kann der Filterkuchen auf nassem oder trockenem Wege entfernt werden.



  Eine Nassentfernung ist sowohl durch Rückspülen mit Wasser als auch mit Klarfiltrat in wenigen Sekunden zu erreichen, wodurch das Filterelement gleichzeitig gereinigt wird. Es kann aber auch Gas im Gegenstrom zur Filtrationsrichtung die Kuchenentfernung bewirken. Die Trocknung des Kuchens kann durch einen Gasstrom in Filtrationsrichtung erfolgen.



  Nach Umkehr des Gasstromes wird der Filterkuchen vollständig durch Schütteln des flexiblen Filterelements entfernt. Der Abwurf des Filterkuchens kann aber auch durch Vibration erfolgen. Zur Trocknung hat sich vorzugsweise das Filterelement gemäss Fig. 4b bewährt. Die Entfernung sowohl des Slurry als auch der trockenen Filterrückstände erfolgt über die Öffnung 13.



   Die Füllung der Filterelemente kann sowohl homogen als auch heterogen sein. Als Füllmaterial sind Füllkörper aus den verschiedensten Materialien und Formen geeignet. So kommen Füllkörper wie beispielsweise Raschignnge und Berlsättel, aber auch Glaskugeln, Steine, Quarzsand, Kohle und Koks in Frage. Raschigringe, welche den Innendurchmesser des Schlauches haben, können säulenförmig übereinandergeschoben werden. An den Stirnflächen müssen sie dann so ausgebildet sein, dass Flüssigkeit in Form von Filtrat durchtreten kann.



  Auch Ringe aus Metall oder Keramik mit seitlich vorhandenen Löchern sind für die erfindungsgemässe Vorrichtung geeignet.



   Ein besonderer Vorteil des erfindungsgemässen Filterelements ist die leichte Entfernbarkeit des Filterkuchens durch die aufgehängten beweglichen Filterschläuche. 



  
 



   The invention relates to a tubular filter element which is suspended in a filter vessel.



   Filter bags of this type are known from DT-AS 2,114,226 and 1,917,306. These hoses are supported from the inside with various elements. Filter hoses without support inserts had not proven their worth, as the filter hose was compressed in the case of heavily soiled media and high pressures. Although the support inserts have improved the filtration properties of such filter elements, they have made the entire filter considerably more expensive due to additional material and the installation of the same.



   It has now surprisingly been found that support inserts, as described in DT-AS 2 114 226, are not required.



   The object of the invention is to create a filter element which can do without the expensive support elements with the same or better filtration performance.



   This object is achieved by a filter element for boiler pressure filters, consisting of a tubular filter medium, and is characterized in that the interior of the filter medium is filled with loose filler material.



   The invention will be described in more detail with reference to drawings.



   It shows:
1 shows a vertical section through a pressure filter with the filter elements according to the invention,
Fig. 2 shows the cross section A-A through the filter of Fig. 1,
3a shows a shortened vertical section through a variant of the filter,
Fig. 3b shows a cross section B-B through the variant of Fig. 3a.



   4a the filter element in longitudinal section,
4b shows a variant of the filter element.



   The arrangement of the filter elements according to the invention in a filter is shown in FIG. In the lower part of the boiler 1, the bottom of which can also be conical, inlet 2 and residue outlet 13 are provided. The boiler 1 can be closed by the cover 5 via the boiler flange 14 and the cover flange 15. In the cover 5 an annular tube 6 is attached in a known manner. The ring pipe 6 is connected to a collecting pipe 7 via a pipe 8. The filter element 9 is attached to the collecting pipe 7 via the connecting piece 11 and the fastening 12. The indicated section in the upper part of the filter element 9 visible on the left in the figure shows the filling material 10.



   In Fig. 2, the arrangement of the collecting pipes 7 to the ring pipe 6 can be seen.



   The lower part of FIG. 3a is the same as that of FIG. In the upper part, a partition plate 16 is attached between the boiler flange 14 and the cover flange 15, which separates the cloudy space in the lower part of the filter from the clear space in the upper part of the filter. The partition plate 16 has bores 17, the number of which corresponds to that of the filter elements 9.



  The filter element 9 is fastened to the connection piece 11 and a fastening ring 12. The ventilation connection piece 4 is provided below the partition plate 16.



   FIG. 3b shows the round openings of the filter elements 9 and the outlet opening 3 for the filtrate that are visible in section B-B of FIG. 3a.



   The filter element 9 according to the invention is shown in a shortened longitudinal section in FIGS. 4a and 4b. The filter means 18 consists of a fabric made of plastics, such as Teflon, nylon, Perlon or natural fibers or fine metal fabrics. The mesh size depends on the size of the solid particles to be filtered off. The interior of the tubular filter is filled with filler material 10.



  A sieve plate 19 forms a barrier so that filling material cannot enter the filtrate space through the nozzle 11.



   In Fig. 4b, a tube 20 is attached in the interior of the filter element 9. Here the sieve plate 19 is located in the lower opening of the tube 20. The filling bodies 10 are located in the space between the filter medium 18 and the tube 20.



   During the filtration, the pulp enters the filter vessel 1 through inlet 2. The pulp can be provided with or without a filter aid. Due to the delivery pressure, the liquid is forced to pass through the filter medium, for example the filter fabric of the tubular filter element 9. The solids are deposited on the outside of the filter hose and are held by the overpressure that prevails in relation to the inside of the filter element 9.



  The compression of the filter hose is prevented by the filling with filling material 10. The sieve plate 19 does not allow the filling material to be pushed out into the filtrate space via the nozzle 11. The clear filtrate is collected in the pipe 7 and flows through the connecting pipe 8 into the ring line 6 in order to leave the filter through the outlet 3.



   At the end of a filtration cycle, the filter cake can be removed wet or dry.



  Wet removal can be achieved in a few seconds by backwashing with water as well as with clear filtrate, whereby the filter element is cleaned at the same time. However, gas in countercurrent to the direction of filtration can also effect the cake removal. The cake can be dried by a gas flow in the direction of filtration.



  After reversing the gas flow, the filter cake is completely removed by shaking the flexible filter element. The filter cake can also be thrown off by vibration. The filter element according to FIG. 4b has preferably proven itself for drying. Both the slurry and the dry filter residues are removed via the opening 13.



   The filling of the filter elements can be both homogeneous and heterogeneous. Packing bodies made of a wide variety of materials and shapes are suitable as the filling material. So fillers such as Raschignnge and Berlsättel, but also glass balls, stones, quartz sand, coal and coke come into question. Raschig rings, which have the inner diameter of the hose, can be pushed one on top of the other in the form of a column. At the end faces they must then be designed in such a way that liquid in the form of filtrate can pass through.



  Rings made of metal or ceramic with laterally present holes are also suitable for the device according to the invention.



   A particular advantage of the filter element according to the invention is that the filter cake can be easily removed due to the suspended, movable filter tubes.
