Abstract
Description
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.
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.
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.
