Beschreibung und Erläuterung zur PatentanmeldungDescription and explanation of the patent application

"Rauchgasreinigunz für kleinere Kesselanlagenl'."Flue gas cleaning for smaller boiler systems.

Es ist bekannt, daß Fesselanlagen, die Öl oder Kohle verbrennen, mit Hauchgasreinigungen versehen werden sollen.It is known that bondage systems that burn oil or coal with Breath gas cleaning should be provided.

Es ist versucht worden, hinter den Kesseln Gewebefilter anzubringen, die mit Kalkstaub beschickt werden, so daß das o°2 aus dem Abgas über den Kalkstaub absorbiert wird.Attempts have been made to fit bag filters behind the boilers, which are charged with lime dust, so that the o ° 2 from the exhaust gas via the lime dust is absorbed.

Die Gewebefilter müssen in entsprechenden Zeitabständen gereinigt werden.The fabric filters must be cleaned at appropriate intervals will.

Hierfür werden vielfach Filterreinigungen verwandt, die mittels Druckluftschock die Filter reinigen.Filter cleanings are often used for this, using compressed air shock clean the filters.

Bei diesem plötzlichen freisetzenden Druckluftstoß wird in dem Kessel ein Rückstoß erzeugt, der vielfach zu kleinen Pufferstößen führt.When this sudden burst of compressed air is released, the boiler a recoil is generated, which often leads to small buffer shocks.

Um dieses zu vermeiden, wird erfindungsgemäß vorgeschlagen, ein Verfahren zu verwenden, das entsprechend beiliegender Zeichnung angewandt wird.In order to avoid this, a method is proposed according to the invention to be used, which is applied according to the enclosed drawing.

In der beiliegenden Zeichnung ist dargestellt: mit (n) ein Kessel; mit (2) das Verbindungsrohr zwischen Kessel (1) und Filter (3), wobei. der Filter gleichzeitig auch mit einem vorgesetzten Chemisorptionsreaktor versehen sein kann; mit (3) der Filter; mit (4) der Ventilator; mit (5) der Abgaskamin.The accompanying drawing shows: with (n) a boiler; with (2) the connecting pipe between the boiler (1) and filter (3), wherein. the filter can also be provided with an upstream chemisorption reactor at the same time; with (3) the filter; with (4) the fan; with (5) the exhaust chimney.

Um den Druckstoß aus dem Filter (3) in den Kessel (1) zu vermeiden, wird ein Verfahren gewahrt, in dem gleichzeitig zur Reiniguncr des Gewebefilters ein Druckschock über eine Düse (6) in das Verlängerungsrohr (2) aufgegeben wird, so daß der Impuls aus dem Gewebefilter (3) durch den Gegendruckschock (h) gegenüber dem Kessel aufgehoben ist und somit Verpuffungsstöße nicht mehr auftreten.To avoid the pressure surge from the filter (3) into the boiler (1), becomes a procedure preserved, in which at the same time for cleaning the Fabric filter applied a pressure shock through a nozzle (6) into the extension tube (2) so that the impulse from the fabric filter (3) by the counter pressure shock (h) is canceled compared to the boiler and therefore deflagration shocks no longer occur.

Selbstverständlich ist die Erfindung nicht auf die vorstehend im einzelnen beschriebenen Ausbildungsformen beschränkt, sondern es sind zahlreiche Abänderungen möglich, ohne jedoch von dem Grundgedanken abzuweichen, einen Druckluftstoß aus dem Filter in Richtung Kessel dadurch wegzukompensieren, indem ein Druckluft stoß über die Düse (6) in dem Verbindungsrohr zwischen Kessel und Filter geschaltet wird.Of course, the invention is not limited to the above in detail The forms of training described are limited, but there are numerous changes possible, without deviating from the basic idea, from a compressed air blast Compensate away the filter in the direction of the boiler by blowing compressed air is switched via the nozzle (6) in the connecting pipe between the boiler and the filter.

Claims (1)

Patentanspruch: Verfahren zur Gasreinigung hinter fossilen Kesselanlagen mittels Gewebefilter dadurch gekennzeichnet, daß in dem Verbindungsrohr (2) zwischen Kessel (1) und Filter (3) eine Düsenanordnung (6) angebracht ist, die gleichzeitig beim Druckschockiinpuls auf die Gewebe taschen im Filter (3) einen Gegendruck erzeugt, so daß die Druckverhältnisse zwischen Filter und Kessel ausgeglichen sind.Claim: Process for gas cleaning behind fossil boiler systems by means of a fabric filter, characterized in that in the connecting pipe (2) between Boiler (1) and filter (3) a nozzle arrangement (6) is attached, which at the same time creates a counter pressure when the pressure shock pulse is applied to the tissue pockets in the filter (3), so that the pressure conditions between the filter and the boiler are balanced.
