Anlage für die Rückspülung von Filterelementen
EMI1.1
<Desc/Clms Page number 2>
Bei der in Fig. 3 dargestellten Ausführungsform besitzt der Behälter 1 an Stelle von Filterkerzen parallel zueinander angeordnete plattenförmige Filterelemente 10, die an ihrer Unterkante jeweils zwei Ausläufe 11 aufweisen, die in je einen von zwei der zueinander parallel durch den Behälter hindurchlaufenden Strangleitungen einmünden. Zu diesem Zweck besitzen die Strangleitungen im dem gegenseitigen Abstand der Filterelemente entsprechenden Abstand voneinander liegende Öffnungen, in welche die Ausläufe 11 der Filterelemente 10 einsteckbar und darin zu befestigen sind. Diebeiden Enden der Strangleitungen sind ebenso wie bei der Ausführungsform nach Fig. 1 und 2 mit je einem Absperrorgan 8 bzw. 9 ausgestattet und an je ein Verteiler-bzw.
Sammelrohr 4 angeschlossen, die über eine Verbindungsleitung 5 mit der ein Absperrventil 7 enthaltenden Zuleitung 6 verbunden sind.
Durch diese Ausbildung der Anlage für die Rückspülung der Anschwemmfilter wird ebenfalls wie bei der erstgenannten Ausführungsform nach Fig. l und 2 ein möglichst direkter Zustrom des Spülmediums zu den Filterelementen gewährleistet, da jedes plattenförmige Filterelement an mehrere Strangleitungen angeschlossen ist, die von beiden Seiten die Zufuhr des Spülmittels gewährleisten können. Dieser beidseitige Zustrom des Spülmediums wird insbesondere durch den beidseitigen Anschluss der Strangleitungen an die Spülmittelzuleitung und durch die Anordnung von je einem Absperrorgan in jedem Strang beiderseits des Behälters 1 ermöglicht. Natürlich kann der erfindungsgemässe beidseitige Anschluss an die Spülmittelzuleitung auch bei Plattenfiltern mit nur einem Auslauf vorgesehen sein.
Bei der Anordnung gemäss der Erfindung ist es möglich, je nach Betätigung der Absperrorgane 8 und 9, die Rückspülung gleichzeitig durch alle oder mehrere Stränge oder aber nur durch einen einzigen
EMI2.1
wird ein restloser Abstoss der an den Filterelementen anhaftenden Filterkuchen gewährleistet. Dies ist unabhängig von der Art des verwendeten Spülmediums der Fall. Die Anlage kann also sowohl mit Pressluft, als auch mit Dampf oder Wasser als Riickspülmittel arbeiten.
PATENTANSPRÜCHE :
1. Anlage für die Rückspülung von reihenweise angeordneten Filterelementen wie z. B. Filterkerzen oder plattenförmigen Trägern mittels Pressluft, Dampf, Wasser oder anderen Flüssigkeiten im Gegenstromverfahren, bei welcher für jede Reihe eine Strangleitung vorgesehen ist, an welche die Filter dieser Reihe unmittelbar angeschlossen sind und die an beiden Enden mit Zuleitungen für das Spülmedium verbunden ist, dadurch gekennzeichnet, dass jede Strangleitung beidseitig, d. h. zwischen den äussersten Filterelementen der Reihe und den Zuleitungen ein Absperrorgan aufweist.

System for backwashing filter elements
EMI1.1
<Desc / Clms Page number 2>
In the embodiment shown in FIG. 3, instead of filter candles, the container 1 has plate-shaped filter elements 10 which are arranged parallel to one another and each have two outlets 11 at their lower edge, each of which opens into one of two of the parallel lines running through the container. For this purpose, the branch lines have openings that correspond to the mutual spacing of the filter elements and into which the outlets 11 of the filter elements 10 can be inserted and secured. As in the embodiment according to FIGS. 1 and 2, the two ends of the branch lines are each equipped with a shut-off device 8 or 9 and are connected to a distributor or
Collector pipe 4 connected, which are connected via a connecting line 5 to the supply line 6 containing a shut-off valve 7.
This design of the system for the backwashing of the precoat filters, as in the first-mentioned embodiment according to FIGS of the detergent. This bilateral inflow of the flushing medium is made possible in particular by the connection of the branch lines to the washing agent supply line on both sides and by the arrangement of a shut-off device in each branch on both sides of the container 1. Of course, the two-sided connection according to the invention to the detergent feed line can also be provided for plate filters with only one outlet.
With the arrangement according to the invention, it is possible, depending on the actuation of the shut-off elements 8 and 9, to backwash simultaneously through all or more lines or through only one
EMI2.1
a complete repulsion of the filter cakes adhering to the filter elements is guaranteed. This is the case regardless of the type of flushing medium used. The system can work with compressed air as well as with steam or water as a backwashing agent.
PATENT CLAIMS:
1. System for the backwashing of filter elements arranged in rows such. B. filter candles or plate-shaped carriers by means of compressed air, steam, water or other liquids in the countercurrent process, in which a branch line is provided for each row, to which the filters of this row are directly connected and which is connected at both ends with feed lines for the flushing medium, characterized in that each branch line on both sides, d. H. has a shut-off device between the outermost filter elements of the row and the supply lines.
