Abstract
Description
Die Erfindung bezieht sich auf ein Filterelement mit den Merkmalen des Oberbegriffs des Patentanspruchs 1.The The invention relates to a filter element with the features of Preamble of claim 1.
Filteranlagen, die der Entstaubung von Gasen oder der Produktrückgewinnung dienen, können als Schlauchfilter ausgebildet sein. In Anlagen dieser Art befindet sich eine Vielzahl von hängend oder liegend angeordneten, unten bzw. an einer Seite geschlossenen und oben bzw. an der anderen Seite offenen Filterschläuchen. Die oberen bzw. offenen Enden der von außen angeströmten Filterschläuche sind über Drahtstützkörbe gezogen und in Öffnungen einer Kopfplatte der Filteranlage befestigt. Die Bauteile des Filterelementes haben die Aufgaben, zum einen eine sichere Halterung des Filterschlauchs an der Kopfplatte zu gewährleisten und zum anderen den Reingasraum oberhalb der Kopfplatte vom Rohgasraum unterhalb der Kopfplatte möglichst dicht getrennt zu halten.Filter systems, which serve the dedusting of gases or the product recovery can as Be formed bag filter. Located in facilities of this kind a variety of hanging or lying horizontally, closed at the bottom or on one side and at the top or on the other side open filter bags. The upper and open ends of the filtered from the outside filter bags are pulled over wire baskets and in openings one Attached top plate of the filter system. The components of the filter element have the tasks, on the one hand a secure mounting of the filter bag to ensure the top plate and on the other hand, the clean gas space above the top plate of the raw gas space as possible below the top plate keep tightly separated.
Während des Betriebs eines Schlauchfilters dieser Art bleibt der Staub auf den Schlauchaußenflächen haften. Die Reinluft gelangt in das Schlauchinnere und strömt durch die obere Öffnung des Filterschlauchs auf die Reingasseite der Filteranlage.During the Operation of a bag filter of this type, the dust remains on the Adhere hose outer surfaces. The clean air enters the tube interior and flows through the upper opening of the filter hose on the clean gas side of the filter system.
Die Abreinigung der Schläuche erfolgt in der Regel reihenweise nacheinander mit Hilfe von kurzen Druckluftstößen aus Düsen von Blasrohren, die oberhalb der Filterschlauchöffnungen angeordnet sind. Die Druckluftstöße werden durch ein jeweils im Einlaßbereich der Filterschläuche angeordnetes Rohrstück eingeblasen. Die Druckluftstöße erzeugen innerhalb der Filterschläuche Druckwellen. Diese bewirken, daß der den Schläuchen von außen anhaftende Staubbelag abgeworfen wird. Über eine unterhalb der Filterschläuche befindliche Schleuse kann der herabgefallene Staub ausgetragen werden.The Cleaning the hoses usually takes place in rows one after the other with the help of short bursts of compressed air Nozzles of Blowpipes, which are arranged above the filter tube openings. The Be compressed air surges through each in the inlet area the filter hoses arranged pipe section blown. Generate the compressed air surges inside the filter bags Pressure waves. These cause the the hoses from the outside adhering dust is discarded. About one below the filter bags located Lock the fallen dust can be discharged.
Bei Filteranlagen dieser Art, die der Entstaubung dienen, sollen die Reingasstaubgehalte möglichst klein sein. Dienen Filteranlagen dieser Art der Produktrückgewinnung, soll der Produktverlust niedrig sein. Die Filterschlauchbefestigungen an der Kopfplatte müssen einerseits diese Bedingungen erfüllen. Andererseits sollen Montage/Demontage der Filterschläuche schnell und sicher ausführbar sein.at Filter systems of this type, which serve the dedusting should, the Clean gas levels possible be small. Serve filter systems of this type of product recovery, the product loss should be low. The filter tube fittings at the headstock need on the one hand meet these conditions. On the other hand, assembly / disassembly of the filter bags should be fast and safely executable be.
Bei einem vorbekannten Filterelement der eingangs erwähnten Art dienen ein mit der Kopfplatte verbundener Spannring und das in das offene Schlauchende hineinragende Rohrstück der Befestigung des Filterschlauchs an der Kopfplatte. Das Rohrstück ist mit einem oberen, nach außen ragenden Kragen ausgerüstet, der sich auf der Kopfplatte abstützt. Spannring und Kragen sind derart mit Keilflächen ausgerüstet, dass sie einen durch Drehen des Rohrstückes betätigbaren Bajonettverschluss bilden. Der Abdichtung von Reingas- und Rohgasseite dient ein in den oberen Rand des Filterschlauchs eingenähter, die Öffnung in der Kopfplatte umgebender Dichtring, der sich im eingebauten Zustand des Filterelementes zwischen dem Kragen des Rohrstückes und der Oberseite der Kopfplatte befindet. Durch die Betätigung des Bajonettverschlusses werden hohe, in axialer Richtung wirkende Dichtkräfte erzeugt. Das Rohrstück kann zur Verbesserung des Reinigungseffektes als Venturirohr ausgebildet sein.at a previously known filter element of the type mentioned serve a connected to the top plate clamping ring and in the open tube end protruding pipe section of the attachment of the filter bag on the top plate. The pipe piece is with an upper, outward equipped with a protruding collar, which is supported on the top plate. Clamping ring and collar are equipped with wedge surfaces in such a way that they through Turning the pipe section actuated Make bayonet lock. The sealing of clean gas and raw gas side one sewn into the upper edge of the filter tube, the opening in the top plate surrounding sealing ring, which is in the installed state the filter element between the collar of the pipe section and the top of the top plate is located. By the operation of the Bayonet closure produces high, acting in the axial direction of sealing forces. The pipe piece Can be designed as a Venturi tube to improve the cleaning effect be.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, die Dichtheit eines Filterelements zu verbessern, ohne die einfache und schnelle Montage/Demontage des Filterschlauchs zu beeinträchtigen.Of the present invention is based on the object, the tightness improve a filter element without the simple and fast Affecting assembly / disassembly of the filter bag.
Erfindungsgemäß wird diese Aufgabe durch die kennzeichnenden Merkmale der Patentansprüche gelöst.According to the invention this Problem solved by the characterizing features of the claims.
Die Anwendung der Erfindung ermöglicht es, die gegenseitige Abdichtung von Reingasseite und Rohgasseite maßgeblich zu verbessern. Dadurch können bei Anlagen, die der Entstaubung dienen, eine Erniedrigung der Reingasstaubgehalte und bei Anlagen, die der Produktrückgewinnung dienen, eine Reduktion der Produktverluste erreicht werden. Die bewährte Befestigungstechnik (Bajonett-Venturi-Technik) kann beibehalten werden. Daraus ergibt sich der weitere wesentliche Vorteil, daß bereits im Einsatz befindliche Schlauchfilteranlagen mit den erfindungsgemäß verbesserten Filterelementen nachgerüstet werden können.The Application of the invention allows it, the mutual sealing of clean gas side and raw gas side decisively to improve. Thereby can In the case of systems that serve dedusting, a reduction in the clean gas dust content and a reduction in equipment used for product recovery the product losses are achieved. The proven fastening technology (bayonet venturi technique) can be retained. This results in the further essential Advantage that already In-use bag filter systems with the inventively improved Retrofitted filter elements can be.
Weitere Vorteile und Einzelheiten der Erfindung sollen anhand eines in der Figur dargestellten Ausführungsbeispieles erläutert werden. Die Figur zeigt ein Filterelement nach der Erfindung, partiell im Schnitt.Further Advantages and details of the invention are based on a in the Figure illustrated embodiment explained become. The figure shows a filter element according to the invention, partially on average.
