Abstract

A backflushing system for gas filters includes a power cylinder which is actuated by the rise in resistance of the filter element. It moves a hinged flushing air tube which contacts the valve on an air receiver and opens it. Nozzles on the air tube enter the clean gas outlets of the filter, seal them and produce a backflushing burst of air. The lower flow resistance of the elements restores the initial position. This is a simple backflushing method and requires a min. of space.

Description

Beschreibung und Erläuterung zur PatentanmeldungDescription and explanation of the patent application

Vorrichtung zur Reinigung von Filterkörpern für die Gasreinigung mittels Spülluftimpuls" Es ist bekannt, Filterkörper, die aus Taschen- oder Rundkörpern bestehen, mittels Druckluftschock oder Spülluft zu reinigen.Device for cleaning filter bodies for gas cleaning by means of Scavenging air pulse "It is known to filter bodies made of pocket or round bodies consist of cleaning by means of a compressed air shock or purge air.

Die beiliegende Zeichnung zeigt den erfindungsgemäßen Gegenstand, der es in einfachster Weise ermöglicht, auf engstem Raum einen Spülluftimpuls wirksam werden zu lassen.The accompanying drawing shows the object according to the invention, which makes it possible in the simplest way to effectively apply a scavenging air pulse in the smallest of spaces to be let.

In der beiliegenden Zeichnung ist dargestellt mit 1: der Filterkörper mit 2: der Rohgaskanal mit 3: der Spülluftsammelraum mit 4: das Spüllufthebebalkenrohr mit 5: der Spülluftschlitzkanal mit 6: ein Gelenk für das Spüllufthebebalkenrohr mit 7: ein Hubzylinder mit 8: das Druckverschlußventil zwischen dem Spülluftsammelraum und dem Spüllufthebebalkenrohr mit 9: die Verschlußfläche zwischen Filterkörper und Spülluftschlitz Arbeitsweise der erfindungsgemäßen Ausführung: Das Rohgas fließt vom Rohgaskanal durch die Filterkörper über die freien Filterflächenausträge dem Reingaskanal oder der umgebenen Atmosphäre zu.In the accompanying drawing is shown with 1: the filter body with 2: the raw gas duct with 3: the scavenging air collecting space with 4: the scavenging air lifting bar pipe with 5: the scavenging air slot duct with 6: a joint for the scavenging air lever tube with 7: a lifting cylinder with 8: the pressure valve between the scavenging air collection chamber and the scavenging air lever tube with 9: the sealing surface between the filter body and purge louvre Mode of operation of the embodiment according to the invention: The raw gas flows from the raw gas duct through the filter body via the free filter surface discharges the clean gas duct or the surrounding atmosphere.

Im Rohgaskanal 2 ist der Spülluftsammelraum 3 angeordnet.The scavenging air collecting space 3 is arranged in the raw gas duct 2.

Dieser ist ständig unter Druck gehalten.This is kept under constant pressure.

Entsprechend der Rohgasbelastuug wird in erforderlichen Abständen, z. B. angesteuert über den Druckverlust des Filters, der Hubzylinder 7, das #püllufthebebalkenrohr mit der Verschlußfläche und dem Spülluftschlitz 9 gegen die abdichtenden Flächen der austretenden Reingasluft heranziehen und dabei gleichzeitig das Druckverschlußventil 8 öffnen, so daß die Druckluft aus dem Luftsammelraum über das Spüllufthebebalkenrohr 4 in die Spülluftschlitzkanalöffnung 5 eindringt, und das Filter durch einen Luftstoß reinigt.According to the raw gas load, at required intervals, z. B. controlled via the pressure loss of the filter, the lifting cylinder 7, the # püllufthebebalkenrohr with the closure surface and the flushing air slot 9 against the sealing surfaces of the exiting clean gas air and at the same time the pressure lock valve Open 8 so that the compressed air from the air collection chamber via the purge air lever tube 4 penetrates into the scavenging air slot channel opening 5, and the filter through a blast of air cleans.

Nach dem Reinigungsvorgang fährt der Hubzylinder 7 in die Ursprungsform zurück und das Filter arbeitet wieder unter den gewünschten Bedingungen.After the cleaning process, the lifting cylinder 7 moves into its original shape back and the filter works again under the desired conditions.

Selbstverständlich ist die Erfindung nicht auf die einzelne Ausbildungsform die dargestellt ist beschränkt, sondern es sind zahlreiche Abänderungen möglich, ohne jedoch von dem Grundgedanken abzuweichen, eine Vorrichtung zur Reinigung von Filterkörpern für die Gasreinigung mittels Spülluftimpuls so zu gestalten, daß die notwendige Filterreinigungsluft über ein Spülluftheberohr mittels Hubzylinder, der das Heberohr betätigt und gleichzeitig den Druckluftverschluß öffnet bzw. schließt, daß zur gegebenen Zeit die notwendige Spülluftmenge zur Reinigung der Filterkörper in den Filterkörper eingelassen wird, wobei gleichzeitig die Einlaßöffnungen durch Dichtflächen, die durch den Hubzylinder an den Ausgang des Filterkörpers herangedrückt werden, voll wirksam in den Filter ausblasen können, ohne daß eine Rückluft aus dem Reingasbereich des Filters ausströmt.It goes without saying that the invention is not limited to the individual form of embodiment which is shown is limited, but numerous modifications are possible, However, without deviating from the basic idea, a device for cleaning To design filter bodies for gas cleaning by means of purge air pulse so that the necessary filter cleaning air via a scavenging air lift tube using a lifting cylinder, the actuates the lifting tube and at the same time opens or closes the compressed air lock, that at the given time the necessary amount of flushing air to clean the filter body is let into the filter body, at the same time the inlet openings through Sealing surfaces that are pressed against the outlet of the filter body by the lifting cylinder be able to blow out fully effectively into the filter without a return air from flows out of the clean gas area of the filter.
