Description

"Verfahren zur Abreinigung von Siebfiltern und Einrichtung zur Durchführung desselben Die"klassische"Abreinigung von Gewebefiltern, z.B. Schlauchfiltern, erfolgt durch einen Spülluftstrom, der die Gewebe in umgekehrter Richtung wie der Rohgasstrom durchsetzt. Gleichzeitig wird die Aufhängevorrichtung fUr die Schläuche mehrmals entspannt und wieder gespannt. Durch das dadurch hervorgerufene mehrmalige Zusammensacken und Wiederaufrichten der Schläuche zerbricht der auf der Piltrierseite anhaftende Filterkuchen und wird dann durch die Spillluft aus dem Piltermedium ausgeblasen."Procedure for cleaning sieve filters and equipment for implementation The "classic" cleaning of fabric filters, e.g. bag filters, takes place by means of a flow of rinsing air that moves the tissue in the opposite direction as the flow of raw gas interspersed. At the same time, the suspension device for the hoses is opened several times relaxed and excited again. Because of the repeated collapse caused by this and erecting the tubes again, the one adhering to the piltration side breaks Filter cake and is then blown out of the pilter medium by the spill air.

Diese Abreinigungsmethode erfordert einen aufwendigen Mechanismus und hohe Wartungskosten. Man hat deshalb versucht, die sogenannte Klopfvorrichtung durch stoßartig pulsierende Spülluft oder durch Vibratorer zu ersetzen, an welchen die Schläuche aufgehängt sind.This cleaning method requires a complex mechanism and high maintenance costs. One has therefore tried the so-called knocking device to be replaced by abruptly pulsating purge air or by vibrators, which the hoses are suspended.

Auf diese Weise wird jedoch, abgesehen von den nicht wesentlich geringeren Anschaffungs- bzw. Betriebs- und Wartungskosten, kein ebenso guter Abreinigungseffekt erzielt wie durch das mehrmalige Einknicken der Schläuche.In this way, however, apart from the not much smaller Acquisition or operating and maintenance costs, not an equally good cleaning effect achieved as if the hoses were buckled several times.

In der Patentanmeldung fr. S 97 548 III/roe wurde ein Verfahren beschrieben, durch welches während der Abreinigungeperiode ohne komplizierten Mechanismus auf einfache Weise das mehrmalige Einknicken der Sc. 11auche bewirkt wirdi Die Filterschläuche sind elstisch gespannt aufgehängt und die Spülluft wird periodisch an- und abachwellend zugeführt. Bei anschwellender Spülluft gibt die elastische Aufhängung nach und die Schläuche knicken ein, während sie sich bei abschwellender Spülluft durch die Wirkung der elastischen Aufhängung wieder aufrichten.In the patent application fr. S 97 548 III / roe a process was described by which on during the cleaning period without a complicated mechanism easy way to buckle the SC several times. 11auche is effectedi the filter bags are hung up and stretched across the table and the scavenging air waves periodically up and down fed. When the purge air increases, the elastic suspension gives way and the Hoses kink as they move through the effect of decongesting rinsing air the elastic suspension upright again.

Es hat sich aber gezeigt, daß bei hoher Filterbelastung und bei sehr feinen Stäuben u.U. auch diese Art der Abreinigung weniger wirksam sein kann als das klassische Abklopfverfahren. Bei letzterem wird nämlich die Fallhöhe der entspannten Aufhängevorrichtung für die Schläuche durch einen mehr oder weniger starren Anschlag begrenzt, wobei Stoßkräfte auf die Schläuche übertragen werden, welche ihre Abreinigung zusätzlich fördern.But it has been shown that with a high filter load and with very fine dusts, this type of cleaning may also be less effective than the classic tapping process. In the latter case, the height of fall becomes the relaxed one Suspension device for the hoses through a more or less rigid stop limited, with impact forces being transmitted to the hoses, which are being cleaned additionally promote.

Erfindungsgemäß wird ohne nennenswerten Eehraufwand auch durch das Verfahren nach Patentanmeldung S 97 548 III/Soe derselbe Abreinigungseffekt erzielt wie durch das alte Abklopfverfahren, wenn in ähnlicher Weise wie bei diesem, die maximale Auslenkung der elastischen Aufhängevorrichtung durch einen starren Anschlag auf eine geringere als die durch Saug- und Spannkraft bedingte stöße begrenzt wird. Dabei ist es zweckmäßig, eine Verstellmöglichkeit für den Anschlag vorzusehen, damit die Größe der Auslenkung und des Stoßeffektes den jeweiligen Verhältnissen angepaßt werden können.According to the invention, the Method according to patent application S 97 548 III / Soe achieves the same cleaning effect as by the old tapping method, if in a similar manner to this one, the maximum deflection of the elastic suspension device due to a rigid stop is limited to impacts that are less than those caused by the suction and clamping force. It is useful to provide an adjustment option for the stop so that the size of the deflection and the impact effect adapted to the respective conditions can be.
