Abstract
Description
Die Erfindung betrifft eine Filtereinheit, insbesondere Pulsfiltereinheit, mit zwei oder mehr Filtern mit einer um eine gedachte Achse geschlossenen, insbesondere zylindrischen oder kegelstumpfförmigen Mantelfläche, die in ihrer Axialrichtung gesehen hintereinander angeordnet sind. Die Erfindung betrifft ferner ein Filterhaus mit einer derartigen Filtereinheit, sowie einen Filter mit einer um eine gedachte Achse geschlossenen, insbesondere zylindrischen oder kegelstumpfförmigen Mantelfläche. Schließlich betrifft die Erfindung ein Verfahren zum Montieren von Filtereinheiten.The The invention relates to a filter unit, in particular pulse filter unit, with two or more filters with a closed about an imaginary axis, in particular cylindrical or frustoconical Shell surface, seen in their axial direction are arranged one behind the other. The invention further relates to a filter house with such Filter unit, as well as a filter with a closed about an imaginary axis, in particular cylindrical or frustoconical lateral surface. Finally, the concerns Invention a method for mounting filter units.
Es sind Filterhäuser bekannt, bei denen mehrere Filtereinheiten aus einem kreiszylindrischen und einem konischen Filter, welche in ihrer Längsachse gesehen hintereinander angeordnet sind, neben und übereinander an einer Halteplatte, in der Fachsprache Header plate genannt, gehalten sind. Die Achsen der Filtereinheiten sind dabei horizontal, also senkrecht zur Erdanziehungskraft angeordnet. Diese Filterhäuser werden zum Entstauben von Luft, beispielsweise der Ansaugluft (Verbrennungsluft) großen Gasturbinen zur Stromerzeugung oder auch zum Ausfiltern von Mehlstaub in industriellen Mühlen oder überall dort, wo große Luftmengen schnell gefiltert werden müssen, eingesetzt. Das Filtermaterial setzt sich dabei langsam mit dem auszufilternden Staub zu. Der Filter müßte dann an sich getauscht werden. Es ist deshalb bekannt, den Filter kurzzeitig und stoßartig entgegen der Strömungsrichtung der zu filternden Luft freizublasen. Der Staub wird so aus dem Filter entfernt und fällt auf den Boden des Filterhauses, wo er durch geeignete Maßnahmen entfernt werden kann.It are filter houses known in which several filter units from a circular cylindrical and a conical filter, which seen in its longitudinal axis one behind the other are arranged, next to and above each other on a holding plate, called in technical language header plate held are. The axes of the filter units are horizontal, ie arranged perpendicular to gravity. These filter houses will be for dedusting air, for example the intake air (combustion air) of large gas turbines for power generation or for filtering flour dust in industrial Mills or everywhere, where big Air volumes need to be filtered quickly, used. The filter material sets Slowly with the dust to be filtered out. The filter would have to to be exchanged. It is therefore known, the filter for a short time and jerky against the flow direction to blow free the air to be filtered. The dust gets out of the filter like that removed and dropped to the bottom of the filter house, where he takes appropriate action can be removed.
Nachteilig bei den bekannten Filtereinheiten ist ihre horizontal liegende Achse. Der auf der Oberseite des Filters freigeblasene Staub fällt wieder auf den Filter zurück, so daß sich der Filter hier sehr schnell wieder zusetzt. Dabei kann bei mehreren übereinander eingeordneten Filtereinheiten der Staub einer oberen Filtereinheit auf eine darunter liegende Filtereinheit fallen und wird hier wieder angesaugt.adversely in the known filter units is their horizontal axis. The dust blown free on the top of the filter falls again back to the filter, so that the filter is added here very quickly. It can with several over each other arranged filter units, the dust of an upper filter unit fall on an underlying filter unit and will be here again sucked.
Hiervon ausgehend liegt der Erfindung zunächst das Problem zugrunde, eine Filtereinheit und ein Filterhaus zu schaffen, bei der die Lebensdauer des Filters erhöht ist, indem ein Zurückfallen von freigeblasenen Staub auf den Filter vermieden wird.Of these, On the basis of the present invention, the problem initially arises to provide a filter unit and a filter house, in which the life of the Filters increased is by falling back free blown dust on the filter is avoided.
Zur Lösung dieses Problems ist die erfindungsgemäße Filtereinheit dadurch gekennzeichnet, daß ihre Achse etwa vertikal angeordnet ist. Das erfindungsgemäße Filterhaus ist mit solchen Filtereinheiten bestückt.to solution In this problem, the filter unit according to the invention is characterized in that its axis is arranged vertically about. The filter house according to the invention is with such Equipped filter units.
Durch die Anordnung der Achse der Filtereinheit in vertikaler Richtung, also in Richtung der Erdanziehungskraft, fällt der freigeblasene Staub nicht mehr auf den Filter zurück, sondern kann ungehindert nach unten auf den Boden des Filterhauses fallen. Dabei werden innerhalb des Filterhauses die Filtereinheiten auch nicht mehr übereinander sondern parallel zueinander neben und hintereinander angeordnet. Vorzugsweise hängen die Filtereinheiten an dem Header plate. Dieses entspricht der Anordnung in bekannten Filterhäusern, nur daß eben die Achse der Filter von der horizontalen in die Vertikale gedreht ist.By the arrangement of the axis of the filter unit in the vertical direction, So in the direction of gravity, the free-blown dust does not fall more on the filter, but can fall freely down to the bottom of the filter house. In the process, the filter units also become inside the filter house no longer on top of each other but arranged parallel to each other next to and behind each other. Preferably hang the filter units on the header plate. This corresponds to the arrangement in known filter houses, only that just the Axis of the filter is turned from horizontal to vertical.
Es ist bereits bekannt, zylindrische oder konische Filter mit ihrer Längsachse vertikal hängend anzuordnen. Dieses wurde bisher jedoch ausschließlich mit einteiligen Filtern durchgeführt. Bei Filtereinheiten aus zwei hintereinander bzw. übereinander angeordneten Filtern ist dieses bisher nicht angewendet worden, da sich der obere, also dem Header plate zugewandte Filter an den Gestellen nur schwer montieren ließ. Während der untere Filter aufgesetzt wurde, fiel der obere Filter herunter. Es bestand also bisher keine Montagemöglichkeit für eine vertikale Anordnung in ihrer Axialrichtung übereinander angeordneten Filtern. Dieses ermöglicht eine Weiterbildung der Erfindung nach der der obere Filter vor einer Montage des unteren Filters mittels eines Halteorgans gegen ungewolltes Abrutschen gesichert ist. Dieses, dem Filter zugeordnete Halteorgan wirkt mit einem Gegenlager am Gestell zusammen und sichert den Filter gegen ein ungewolltes Herunterrutschen.It is already familiar with cylindrical or conical filters with their longitudinal axis to arrange vertically hanging. However, this has so far been exclusively with one-piece filters carried out. For filter units of two consecutively arranged or one above the other This filter has not yet been used, since the upper, So the header plate facing filter on the racks difficult to assemble left. While the lower filter was placed, the upper filter fell down. So far there was no mounting option for a vertical arrangement in their axial direction one above the other arranged filters. This allows a development of the invention according to the upper filter in front of a Assembly of the lower filter by means of a holding member against unwanted Slipping is secured. This, the filter associated holding member interacts with an abutment on the frame and secures the filter against an unwanted slipping down.
Der obere Filter wird also zunächst durch ein Halteorgan gleichsam zwischengelagert. Nach der Montage des unteren Filters kann der obere Filter dann wieder analog des Standes der Technik mit zwei horizontal angeordneten Filtern durch den unteren Filter gehalten werden.Of the upper filter will be so first temporarily stored as it were by a holding device. After assembly of the lower filter, the upper filter can then again analogous to Prior art with two horizontally arranged filters by the lower filter are kept.
Als Gegenlager eignet sich eine Platte, die mit einer oder mehreren Ausnehmungen versehen ist. Am Filter werden als Halteorgan korrespondierende Finger vorgesehen, deren Anzahl insbesondere der Anzahl der Schlitze der Platte entspricht. Der Filter kann so auf das Gestell aufgeschoben werden, wobei die Finger durch die Schlitze an der Platte hindurch geführt werden. Durch anschließendes Verdrehen des Filters um seine Achse geraten die Finger außer Flucht mit den Schlitzen und der Filter kann mittels der Finger vorrübergehend auf der Platte abgesetzt werden.When Counter bearing is a plate that is compatible with one or more Recesses is provided. On the filter are corresponding as holding member Finger provided, the number of which, in particular, the number of slots corresponds to the plate. The filter can be pushed onto the frame with your fingers passing through the slots on the plate guided become. By subsequent Turning the filter around its axis makes the fingers run away with the slits and the filter can be temporary by means of the fingers be deposited on the plate.
Alternativ ist es auch möglich, daß Gegenlager oder das Halteorgan schwenkbar bzw. anklappbar auszubilden, derart, daß das Halteorgan bzw. das Gegenlager verschwenkt, wenn der Filter aufgeschoben wird. Das Halteorgan bzw. das Gegenlager gelangen dann in ihre ursprüngliche Position zurück und halten den Filter. Dies kann durch entsprechende Anschläge geschehen. Dieses hätte aber den Nachteil, daß das Halteorgan bzw. das Gegenlager für eine gewollte Demontage des Filters manuell angeklappt werden muß, was unter Umständen schwierig sein kann. Deshalb ist es alternativ auch möglich Federn vorzusehen, die ein Abklappen des Halteorgans bzw. des Gegenlagers verhindern, solange der Filter auf dem Gegenlager ruht. Die Federn halten in diesem Fall das Gewicht des Filters. Wird der Filter aber gewollt abgezogen, wird die Kraft der Federn überwinden und das Halteorgan bzw. das Gegenlager klappen in die zur Montage des Filters entgegen gesetzte Richtung um.Alternatively, it is also possible that counter bearing or the retainer pivotable or hinged bar form, such that the holding member or the anvil pivots when the filter is pushed. The retainer or the counter bearing then return to their original position and hold the filter. This can be done by appropriate attacks. But this would have the disadvantage that the retainer or the anvil must be manually folded for a deliberate disassembly of the filter, which may be difficult under certain circumstances. Therefore, it is alternatively also possible to provide springs which prevent folding of the holding member or the abutment, as long as the filter rests on the abutment. The springs in this case hold the weight of the filter. But if the filter is subtracted deliberately, the force of the springs will overcome and the retainer or the counter-bearing fold in the opposite direction for mounting the filter direction.
