Description
Filteranlage, insbesondere Schnellfilteranlage, mit einem Filterboden Die Erfindung bezieht sich auf eine Filteranlage, insbesondere Schnellfilteranlage, mit einem Filterboden, der das Filterbett trägt, das Filtrat abführt und dem Waschmittel (beispielsweise Druckluft und Waschwasser) während der Filterwäsche den Durchtritt gestattet. Bei diesen bekannten Anlagen stellt der Filterboden das Hauptelement dar, da er verschiedene Funktionen auszuüben hat. Mithin ergeben sich verhältnismäßig teure Anlagen, die namentlich bei offener Bauweise ausschlaggebend ins Gewicht fallen. Filter system, in particular quick filter system, with a filter base The invention relates to a filter system, in particular a quick filter system, with a filter base, which carries the filter bed, removes the filtrate and the detergent (e.g. compressed air and washing water) during the filter wash the passage allowed. In these known systems, the filter base is the main element because he has to perform various functions. Hence arise proportionally expensive systems, which are particularly important in the case of open construction.
Die Filterböden werden üblicherweise in einer Ausdehnung ausgeführt, die der Ausdehnung des Filterbettes entspricht. Es ergeben sich hierdurch große Spannweiten, die nur geringen Belastungen ausgesetzt werden können. Bei Filterbetthöhen z. B. von 2000 oder 3000 mm Schichthöhe ergeben sich somit statisch bedingte teuere Konstruktionen. Man hat deshalb bisher, namentlich bei offenen Filtern, von hohen Filterschichten Abstand genommen und nur Filter bis etwa 2200 mm Filterbetthöhe ausgeführt und auf die Vorzüge von höheren Filterbetten, z. B. The filter bottoms are usually designed in one extension, which corresponds to the expansion of the filter bed. This results in large ones Spans that can only be exposed to low loads. At filter bed heights z. B. of 2000 or 3000 mm layer height thus result in statically-related expensive Constructions. So up to now, especially with open filters, one has had high Filter layers removed and only filters up to about 2200 mm filter bed height executed and on the merits of higher filter beds, z. B.
3000 mm, der Kosten wegen verzichtet. Die Wirkung der Filterwäsche hängt naturgemäß von der angewandten Luft- und Waschwassermenge ab; diese wiederum vpn der Filterwäscbe. Je größer die Filterfläche, desto größer die Luftmengen und die Waschwassermengen. Es ergeben sich somit große Gebläse und große Waschwasserpumpen. Würde man z. B. die gleichen Luftmengen und die gleichen Waschwassermengen im richtigen Verhältnis zueinander für die glatte Filterfläche wie bisher anwenden, so könnte man hierdurch einen besseren Wascheffekt in wesentlich kürzerer Zeit erzielen.3000 mm, waived because of the costs. The effect of filter washing naturally depends on the amount of air and washing water used; this in turn vpn of the filterwash. The larger the filter surface, the greater the air volume and the amounts of washing water. This results in large fans and large washing water pumps. Would you z. B. the same amounts of air and the same amounts of washing water in the right Apply ratio to each other for the smooth filter surface as before, so could you can achieve a better washing effect in a much shorter time.
Die Erfindung beseitigt die vorstehend erörterten Nachteile dadurch, daß bei einer Verkleinerung der Breite des Filterbodens auf die Hälfte die Höhe des Filterbettes im Vergleich zu Filterbetten mit parallelen Begrenzungswänden verdoppelt ist. The invention overcomes the disadvantages discussed above in that that when the width of the filter base is reduced to half the height of the filter bed is doubled compared to filter beds with parallel boundary walls is.
Diese erfindungsgemäße Durchbildung ergibt sich aus der nachstehenden mathematischen Bezeichnung: Wenn bei einem Zylinder-Filterbett das Volumen des Filterbettes mit Vf angeordnet wird und die Fläche des Filterbodens mit F bezeichnet wird, dann ergibt sich für die Höhe des Filterbettes H =. This development according to the invention results from the following Mathematical designation: If, in the case of a cylinder filter bed, the volume of the filter bed is arranged with Vf and the area of the filter bottom is denoted by F, then results for the height of the filter bed H =.
F Wird die Fläche des Filterbodens z. B. auf die Hälfte reduziert, also auf F2 F dann ergibt sich bei 2 gleichem Filterbettvolumen und gleicher Filterbettfläche für die Höhe die Ausgangsformel Vf 2H Vf F2 Anders ausgedrückt, erweist es sich nach der Erfindung als ein besonderer Vorteil, daß bei geringerer Filterbodenfläche und dementsprechend geringen Kosten für den Boden ein gleichbleibendes Volumen des Filterbettes durch Erhöhen der Filterbenthöhe zustande kommt. Dies schließt den zusätzlichen Vorteil in sich ein, daß sich ein längerer Filtrationsweg und infolgedessen ein besseres Filtrat erreichen läßt. Es kann beispielsweise ein Filterbett, das bisher 1500 mm Schichthohe aufweist, nunmehr eine solche von 3000 mm erhalten. Gleichzeitig wird in vorteilhafter Weise eine Verringerung der Bau- und Materialkosten für die unter dem Filterboden befindliche Reinwasserkammer erreicht, da diese von dem kleinen Filterboden ausgeht. F If the area of the filter base is e.g. B. reduced by half, So on F2 F then results with 2 the same filter bed volume and the same filter bed area for the height the starting formula Vf 2H Vf F2 In other words, it turns out according to the invention as a particular advantage that with a smaller filter base area and a correspondingly low cost for the soil a constant volume of the Filter bed comes about by increasing the filter bed height. This includes the additional advantage in that there is a longer filtration path and, as a result a better filtrate can be achieved. For example, it can be a filter bed that previously had a layer height of 1500 mm, now one of 3000 mm has been obtained. Simultaneously is a reduction in construction and material costs for the advantageous manner Reached the pure water chamber located under the filter base, as this is covered by the small Filter bottom goes out.
In der Zeichnung ist die Erfindung schematisch dargestellt. The invention is shown schematically in the drawing.
