Description
Die Erfindung betrifft einen filternden Abscheider, der mit Filterpatronen oder Filtertaschen und einer Druckluft-Impulsabreinigung ausgerüstet ist.The The invention relates to a filtering separator associated with filter cartridges or filter bags and a compressed air pulse cleaning is equipped.
Bei bekannten Vorrichtungen zur Abreinigung filternder Abscheider werden über Druckluftsysteme, bestehend aus Druckluftbehälter, schnell reagierenden Ventilen und Treibdüsen, Freistrahlen erzeugt, die in die Filterelemente eingeleitet werden und diese durch entstehende Trägheitskräfte und Spüleffekte vom anhaltenden Staub befreien. Der abgereinigte Staub fällt rohgasseitig nach unten und wird über einen Staubbunker und entsprechende Austragorgane aus dem Abscheider gefördert und entsorgt.at known devices for cleaning filtering separators are compressed air systems, consisting of compressed air tank, fast-reacting valves and motive nozzles, free-jet generated, which are introduced into the filter elements and this caused by Inertial forces and rinsing effects free from the persistent dust. The cleaned dust falls on the raw gas side down and over a dust bunker and corresponding discharge organs from the separator promoted and disposed of.
Zur Verbesserung der Abreinigungseffekte wurden eine Reihe Lösungen vorgeschlagen, die z. B. der Energieeinsparung dienen und eine Vergleichmäßigung der Luftbeaufschlagung der Filterelemente bezwecken. So ist es z. B. bekannt, die Treibdüsen mit düsenförmigen Injektoren zu kombinieren, um ohne zusätzlichen Aufwand an Druckluft eine größere Spülluftmenge zur Abreinigung zur Verfügung zu stellen. Ebenso ist es bekannt, in den Filterelementen Einbauten anzuordnen, um die Druckluftmenge zu reduzieren und eine Vergleichmäßigung der Abreinigung zu erreichen. Es wurde auch vorgeschlagen, die in der Regel konzentrisch zum Filterelement angeordneten Treibdüsen mit kreisförmig um diese angeordneten kleinen Düsen zu kombinieren, um die Abreinigung der Filterelemente insbesondere im oberen Bereich zu verbessern.to To improve the cleaning effects, a number of solutions have been proposed. the z. As the energy saving and equalization of Air treatment of the filter elements purpose. So it is z. B. known to use the motive nozzles nozzle-shaped injectors to combine, without additional Expense of compressed air a larger purge air for cleaning available to deliver. It is also known in the filter elements internals order to reduce the amount of compressed air and a homogenization of To achieve cleaning. It was also suggested that in the Usually concentric with the filter element arranged driving nozzles with circular around these arranged small nozzles To combine, in particular, the cleaning of the filter elements to improve in the upper area.
Alle diese Lösungen sind darauf gerichtet, die Beaufschlagung der Filterelemente mit Spülluft von innen zu verbessern und dabei eine gute Energieökonomie zu erreichen. Insbesondere bei hochdispersen, schwer sedimentierbaren Feinstäuben zeigt sich aber, dass die Ablösung der Staubschichten an den Filterelementen zwar funktioniert, dass aber ein Teil des abgeschiedenen Staubes in den relativ kurzen Abreinigungszeiten nicht ausreichend ausgetragen wird, sondern in der Schwebe bleibt und nach dem Ende der Regenerierung sofort wieder am Filterelement anhaftet. Das hat zur Folge, dass höhere Druckverluste auftreten und die Abreinigungsintervalle verkürzt werden müssen, was wiederum zu höheren Energieaufwendungen führt.All these solutions are directed to the loading of the filter elements with Purge air from improve and achieve a good energy economy. Especially shows highly dispersed, hardly sedimentable fine dusts but that, the detachment Although the dust layers on the filter elements work, but that a part of the separated dust in the relatively short cleaning times is not sufficiently discharged, but remains in the balance and immediately after the end of the regeneration again on the filter element adheres. This has the consequence that higher pressure losses occur and the cleaning intervals need to be shortened, which turn to higher Energy expenditures leads.
Aus
Aufgabe der Erfindung ist es, eine möglichst einfache Einrichtung zu schaffen, die ein erneutes Anhaften von bereits abgeschiedenem Staub verhindert und damit den Energieaufwand zum Betreiben filternder Abscheider reduziert.task The invention is to be as simple as possible Establish a facility that is a re-adhesion of already deposited Dust prevents and thus the energy required to operate filtering Separator reduced.
Diese Aufgabe wird durch die Merkmale des Patentanspruchs 1 gelöst. Die weiteren Ansprüche enthalten besonders vorteilhafte Ausgestaltungen der Erfindung. Mit der Erfindung wird erreicht, dass der abgereinigte Staub unmittelbar nach der Ablösung vom Filterelement nach unten zum Staubbunker befördert wird und dass auch benachbarte Filterelemente, die nicht abgereinigt werden, abgeschirmt werden und so ein Anhaften von bereits abgeschiedenen Staub an diesen verhindert wird.These The object is solved by the features of claim 1. The further claims included particularly advantageous embodiments of the invention. With the invention is achieved that the cleaned dust immediately after the replacement from the filter element down to the dust bin is transported and that also adjacent Filter elements that are not cleaned, shielded and thus prevents adhesion of already deposited dust to them becomes.
