Abstract

Regenerating a filter surface, comprises providing the filter medium surface with an air impulse which is dependent on the flow material properties and agglomeration on the filter medium. The air is supplied via nozzles. Values are registered and processed in order to control the air pressure and nozzle cross-section.

Description

Stand der TechnikState of the art

Beim Handeln von brennbaren Stäuben kommt es immer wieder zu Explosionen. Bei diesen Explosionen treten Flammen, Staub und Funken aus, die zu Sekundär­ explosionen führen können. Um die Druckdifferenz und das Staubluftgemisch im Filterapparat besser unter Kontrolle zu halten, werden Druckdifferenzmessungen durchgeführt, die dann die Regenerierung der Filterfläche einleiten. Hierzu sind verschiedene Verfahren bekannt, die sehr kostenintensiv und aufwendig sind. Explosions occur again and again when handling flammable dusts. With these Explosions emanate flames, dust and sparks that become secondary can cause explosions. Better by the pressure difference and the dust-air mixture in the filter apparatus To keep it under control, pressure difference measurements are carried out, which are then the regeneration the filter surface. Various methods are known for this, which are very expensive and are expensive.  

AufgabenstellungTask

Es gilt eine Vorrichtung und ein Verfahren zu schaffen, die in explosionsgefährdeten Räumen angewandt werden kann. The aim is to create a device and a method that can be used in potentially explosive areas can be applied.  

Lösungsolution

Die Erfindung löst die Aufgabenstellung dadurch, daß die üblichen DSM-Meßstreifen und elektronischen Druckaufnehmer nicht zum Einsatz kommen, sondern daß entsprechende Schaltpunktmeßgeräte zum Einsatz kommen, die eine Öffner oder eine Schließerfunktion beinhalten und über eine elektrische Barriere zum eigentlichen Steuergerät geleitet werden und die Regenerierung dadurch auslösen.The invention solves the problem in that the usual DSM measuring strips and electronic pressure transducers are not used, but that appropriate Switching point measuring devices are used that contain an NC or a NO function and are passed over an electrical barrier to the actual control unit and the regeneration thereby trigger.

Verfahren und Vorrichtung dadurch gekennzeichnet, daß die Regenerierung der Filterfläche mit einem Luftimpuls abhängig von der Schüttguteigenschaft und des Agglomerationsverhaltens auf dem Filtermedium geregelt wird mit Düsen und Druck des Luftimpulses. Dadurch gekennzeichnet, daß die Werte registriert, bearbeitet und im Ergebnis den Druck des Luftimpulses regelt und bei Verlassen des Druckes die Änderung des Düsenquerschnittes anzeigen.Method and device characterized in that the regeneration of the filter surface with an air pulse is regulated depending on the bulk property and the agglomeration behavior on the filter medium with nozzles and pressure of the air pulse. Characterized in that the values are registered, processed and, as a result, regulates the pressure of the air pulse and indicate the change in the nozzle cross section when the pressure is exited.
