Die Erfindung/Neuerung liegt die Aufgabe zugrunde, ein Verfahren zur Reduzierung des Feinstaubanteils in der Abluft einer Kleinfeueranlage anzugeben, bei dem ein mehrfach verwendbarer Filter auf einfache Weise gereinigt werden kann, im Filter zurückgehaltene Partikel auf einfache Weise und schmutzfrei aus dem Filter entsorgt werden können und der Ofen auch in einer Anheizphase einfach betreibbar ist. Diese Aufgabe wird dadurch gelöst, dass der Filter von einer in einem Abzugsbereich der Rauchgase angeordneten Filterstellung, in welcher die Rauchgase den Filter durchsetzen, in eine Regenerierungsstellung verbringbar ist, in welcher er von Rauchgasen nicht mehr durchsetzt wird und Partikel entweder aus dem Filter in den Feuerraum abgegeben werden oder durch Einwirkung von Hitzestrahlung oder -konvektion aus dem Feuerraum verbrannt werden.The invention / innovation is based on the object of specifying a method for reducing the proportion of fine dust in the exhaust air of a small fire system, in which a reusable filter can be cleaned in a simple manner, particles retained in the filter can be disposed of in a simple manner and dirt-free from the filter and the oven is easy to operate even in a heating phase. This object is achieved in that the filter of a arranged in a vent region of the flue gases filter position in which the flue gases pass through the filter can be brought into a regeneration position in which it is no longer permeated by flue gases and particles either from the filter in the Firebox are delivered or burned by the action of heat radiation or convection from the firebox.
Als Kern der Erfindung/Neuerung wird es angesehen, einen zwischen wenigstens zwei Positionen verfahrbaren Filter vorzusehen, wobei eine Position eine Filterstellung ist, in welcher die Rauchgase den Filter durchsetzen und der Filter von dieser Filterstellung dann in eine Regenerierungsstellung verbracht werden kann, in welcher er beim Filtervorgang im Filter zurückgehaltene Partikel in den Feuerraum abgeben kann oder auf der Filteroberfläche zurückgehaltene Rauchgaspartikel durch Einwirkung von Hitze infolge Strahlung oder Konvektion verbrannt werden. In dieser Regenerierungsstellung ist außerdem der Rauchgaskanal völlig frei, so dass es zweckdienlich ist, während einer Anzündphase den Filter in der Regenerierungsstellung zu halten, so dass auch bei schlechter ziehenden Kaminen sich zunächst ein kräftiges Feuer entwickeln kann, dann den Filter in die Filterstellung einzuschwenken oder einzufahren, um Partikel während der Phasen "Trocknung des Brennstoffes", "Austreibung des Kohlenstoffes aus dem Brennstoff" und "unvollständige Verbrennung" abzufiltern und während einer vollständigen Verbrennung des Brennstoffes den Filter sodann in die Regenerierungsstellung zu verbringen, in der er die Partikel entweder in Folge von Schwerkraft in den Feuerraum abgeben kann oder die Partikel durch Einwirkung von Hitze auf der Oberfläche des Filters verbrannt werden. Wenn dieser Regenerierungsvorgang abgeschlossen ist, ist der Filter wieder einsetzbar und kann entweder sogleich oder nach einer weiteren Anzündphase in den Rauchgaskanal der Kleinfeueranlage eingeschwenkt werden.As a core of the invention / innovation it is considered to provide a movable between at least two positions filter, wherein a position is a filter position in which the flue gases pass through the filter and the filter of this filter position are then moved to a regeneration position can be in which it can give off particles retained in the filter during the filtering process in the furnace or on the filter surface retained flue gas particles are burned by the action of heat due to radiation or convection. In this regeneration position, the flue gas duct is also completely free, so that it is expedient to keep the filter in the regeneration position during an ignition phase, so that a strong fire can initially develop even with badly pulling chimneys, then swivel the filter into the filter position or to retract particles during the phases "drying of the fuel", "expulsion of the carbon from the fuel" and "incomplete combustion" and then, during complete combustion of the fuel, to transfer the filter to the regeneration position, where it deposits the particles either in The result of gravity can be released into the combustion chamber or the particles are burned by the action of heat on the surface of the filter. When this regeneration process is completed, the filter is reusable and can be pivoted either immediately or after a further ignition phase in the flue gas duct of the small fire system.

Relate to a small fire system for carrying out the method according to one of claims 1-13.
Mit Vorteil wird das Verfahren weitergebildet, wenn sich in der Regenerationsstellung des Filters im Filter festgesetzte Teilchen in Folge von Schwerkraft aus dem Filter lösen. Der Filter kann dazu z. B. eine offene Seitenwand aufweisen, die in Regenerationsstellung nach unten geführt wird, um Partikel aus einem Filterinnenbereich abzugeben.Advantageously, the process is further developed if, in the regeneration position of the filter, particles fixed in the filter detach from the filter as a result of gravity. The filter can be z. B. have an open side wall, which is guided in the regeneration position down to deliver particles from a filter inner region.
Es ist auch möglich, den Filter in der Regenerationsstellung durch ein Vibrationselement zu beaufschlagen oder den Filter gegen einen Anschlag zu fuhren, so dass durch mechanische Vibrationsenergie oder Auftreffenergie des Filters auf dem Anschlag Teilchen von der Filteroberfläche gelockert und gelöst werden.It is also possible to apply the filter in the regeneration position by a vibrating element or to drive the filter against a stop, so that are loosened by mechanical vibration energy or impact energy of the filter on the stop particles from the filter surface and dissolved.
Als Filtermaterial kann ein keramisches Material verwendet werden, z. B. eine Schaumkeramik Der Filter kann in der Regenerationsstellung z. B. auf einer Temperatur von wenigstens 800° C gehalten werden. Dies ist eine Temperatur, die eine Art Pyrolysevorgang auf der Filteroberfläche auslöst, so dass der Filter zusätzlich zur mechanischen Entleerung und Reinigung quasi abgebrannt wird Der Filter kann beim Verfahren von der Filterstellung in die Regenerationsstellung eine Schwenkbewegung durchführen, d. h. er ist einseitig an einer Schwenkachse gelagert, die mit einer an der Kleinfeueranlage außen angebrachten Handhabe gekoppelt ist, um die Schwenkbewegung durchführen. Es ist auch möglich, die Schwenkbewegung des Filters mit einer Vertikalbewegung zu koppeln, d. h. der Filter kann zunächst von einer horizontalen Filterstellung in eine vertikale Regenerationsstellung verbracht werden und dann in dieser Vertikalstellung noch nach unten in eine Position gefahren werden, wo die Hitzeeinwirkung besonders groß ist. Dabei ist es zusätzlich vorteilhaft, den Filter entlang seines vertikalen Verfahrweges durch vertikales Rütteln auszuklopfen, um eine möglichst weitgehende Entfernung von Partikeln zu erreichen.As a filter material, a ceramic material may be used, for. B. a foam ceramic The filter can be in the regeneration position z. B. be maintained at a temperature of at least 800 ° C. This is a temperature that triggers a kind of pyrolysis process on the filter surface, so that the filter is quasi burned in addition to the mechanical emptying and cleaning. The filter can perform a pivoting movement in the process of the filter position in the regeneration position, d. H. he is unilaterally mounted on a pivot axis, which is coupled to a mounted on the small fire system outside handle to perform the pivoting movement. It is also possible to couple the pivoting movement of the filter with a vertical movement, d. H. the filter can first be moved from a horizontal filter position to a vertical regeneration position and then, in this vertical position, moved down to a position where the effect of heat is particularly great. It is additionally advantageous to tap the filter along its vertical travel by vertical shaking in order to achieve the greatest possible removal of particles.
In der Regenerationsstellung kann der Filter in Höhe des Feuerrostes oder unmittelbar neben der Abbrandstelle gehalten werden. Die Regenerationsstellung befindet sich innerhalb des Feuerraumes, dadurch ist es besonders einfach möglich, dass die Teilchen, die aus dem Filter herausfallen oder in Folge der Hitzeeinwirkung sich von der Filteroberfläche lösen, in den Feuerraum fallen. Eine Verschmutzung des Umgebungsbereiches der Kleinfeueranlage durch Filtersäuberung ist damit ausgeschlossen. Der Filter kann eine plattenartige oder wabenartige oder sonstige poröse Struktur haben, die geeignet ist, dass Rauchgase ohne allzu großen Stau durch das Filtermaterial hindurchgeführt werden.In the regeneration position, the filter can be kept at the height of the grate or immediately next to the erosion point. The regeneration position is located within the firebox, which makes it particularly easy for the particles that fall out of the filter or, due to the effect of heat, to fall off the filter surface, to fall into the firebox. Pollution of the surrounding area of the small fire system by filter cleaning is thus excluded. The filter can be a plate-like or have honeycomb or other porous structure, which is suitable that flue gases are passed through the filter material without too much congestion.
In Weiterbildung der Erfindung ist es auch noch möglich, den Filter nach jedem Regenerationsvorgang derart zu wenden, dass dem Feuerraum abwechselnd sich gegenüberliegende Oberflächen des Filters zugewandt sind.In a development of the invention, it is also possible to apply the filter after each regeneration process in such a way that the combustion chamber alternately faces opposite surfaces of the filter.
Der Filter ist mit einer Schwenk- oder Hebevorrichtung aus der Regenerationsstellung in die Filterstellung anzuheben und wird dabei in eine Stellung geschwenkt, die zur Regenerationsstellung im Wesentlichen rechtwinklig ist.The filter is to lift with a swivel or lifting device from the regeneration position in the filter position and is thereby pivoted to a position which is substantially perpendicular to the regeneration position.
Die Kleinfeueranlage zur Durchführung des Verfahrens umfasst eine Brennkammer zum Abbrand des festen Brennstoffes, einen Abzugsbereich sowie einen Filter, der in einer Filterstellung vom Rauchgas durchströmt wird und in einer nichtfilternden Stellung den Rauchgaskanal freigibt. In der nichtfilternden Regenerationsstellung nimmt der Filter eine Lage ein, in der zurückgehaltene Teilchen von der Filterfläche abfallen können oder auf der Filterfläche verbrannt werden können.The small fire system for carrying out the method comprises a combustion chamber for burning off the solid fuel, a take-off region and a filter, which is traversed by the flue gas in a filter position and releases the flue gas channel in a non-filtering position. In the non-filtering regeneration position, the filter occupies a position in which retained particles may fall off the filter surface or be burned on the filter surface.
