Aufgabe der Erfindung ist es, die genannten Nachteile zu vermeiden und auf platzsparende Weise die Rauchgase von Hausbrand-Feuerungsanlagen effektiv zu reinigen, wobei besonderes Augenmerk auf einfache Nachrüstbarkeit in bestehende Feuerungsanlagen gerichtet werden soll.The object of the invention is to avoid the disadvantages mentioned and to effectively clean the flue gases of domestic fire furnaces in a space-saving manner, with particular attention to be directed to simple retrofitting in existing firing systems.
Erfindungsgemäß wird dies dadurch erreicht, dass die Elektroden durch einen die Stäbe oder Platten umfassenden, vorzugsweise ringförmigen Leiter miteinander verbunden sind.According to the invention, this is achieved in that the electrodes are connected to one another by a preferably annular conductor comprising the rods or plates.
Die Elektroden sind vorteilhafterweise drehsymmetrisch bezüglich der Strömungsachse der Rauchgasströmung, insbesondere drehsymmetrisch bezüglich der Mittelachse des Schornsteins angeordnet.The electrodes are advantageously rotationally symmetrical with respect to the flow axis of the flue gas flow, in particular arranged rotationally symmetrical with respect to the center axis of the chimney.
Eine hohe Ionisierung kann erreicht werden, wenn die Elektroden konzentrisch zum ringförmigen Leiter angeordnet sind. Dabei ist es besonders vorteilhaft, wenn die Elektroden im Wesentlichen sternförmig angeordnet sind.High ionization can be achieved when the electrodes are concentric with the annular conductor. It is particularly advantageous if the electrodes are arranged substantially in a star shape.
Alternativ oder zusätzlich dazu kann in einer herstellungsmäßig einfachen Ausführung vorgesehen, dass die durch Platten gebildeten Elektroden sich im Bereich der Strömungsachse schneiden und miteinander verbunden sind.Alternatively or additionally, it may be provided in a manufacture that is simple in terms of manufacture that the electrodes formed by plates intersect in the region of the flow axis and are connected to one another.
Ein einfacher nachträglicher Einbau in bestehende Hausbrand-Feuerungsanlagen ist möglich, wenn der Elektrofilter im Bereich des Schornsteins, vorzugsweise im Endbereich des Schornsteins, angeordnet ist, wobei vorzugsweise der Elektrofilter als Schornsteinaufsatz ausgebildet ist.A simple subsequent installation in existing domestic firing systems is possible if the electrostatic precipitator in the region of the chimney, preferably in the end region of the chimney, is arranged, wherein preferably the electrostatic filter is designed as a chimney cowl.
Um ein einfaches Reinigen des Elektrofilters zu ermöglichen, ist es besonders vorteilhaft, wenn der Schornsteinaufsatz lösbar mit dem Schornstein verbunden ist, wobei vorzugsweise der Schornsteinaufsatz am Schornstein aufsteckbar oder über ein Drehgelenk mit diesem klappbar verbunden ist.In order to enable a simple cleaning of the electrostatic precipitator, it is particularly advantageous if the chimney cowl is releasably connected to the chimney, wherein preferably the chimney cowl is attachable to the chimney or hingedly connected thereto by a hinge.
Für eine zuverlässige und dauerhafte Funktion des Elektrofilters ist es vorteilhaft, wenn die Ionisationskammer durch ein Keramik-Innenrohr gebildet ist. Dadurch, dass die Wände der Ionisationskammer durch elektrisch isolierende Keramik gebildet sind, wird die Gefahr der Bildung von elektrisch leitenden Brücken durch sich ablagernde Partikel minimiert. Das Keramik-Innenrohr umgibt dabei vorteilhafterweise die Filterelektrodenanordnung.For a reliable and permanent function of the electrostatic filter, it is advantageous if the ionization chamber is formed by a ceramic inner tube. The fact that the walls of the ionization chamber are formed by electrically insulating ceramic, the risk of formation of electrically conductive bridges is minimized by depositing particles. The ceramic inner tube advantageously surrounds the filter electrode arrangement.
Um hohe Abscheideraten zu ermöglichen, ist es vorteilhaft, wenn stromabwärts und fluchtend mit der Ionisationskammer ein gerader Abscheidebereich angeordnet ist, wobei vorzugsweise der Abscheidebereich durch ein vorzugsweise aus nicht-rostendem Stahl bestehendes Abscheiderohr gebildet ist, dessen Achse fluchtend zur Strömungsachse des Schornsteins angeordnet ist, und wenn stromaufwärts der Ionisationskammer ein Einschubrohr aus nicht-rostendem Stahl angeordnet ist, dessen Achse fluchtend zur Achse der Ionisationskammer und zur Achse des Abscheidebereiches ausgerichtet ist.In order to enable high deposition rates, it is advantageous if a straight separation region is arranged downstream of and in alignment with the ionization chamber, wherein preferably the separation region is formed by a separator tube, preferably made of stainless steel, whose axis is aligned with the flow axis of the chimney, and when upstream of the ionization chamber, there is disposed a stainless steel insert tube whose axis is aligned with the axis of the ionization chamber and with the axis of the deposition region.
Um eine einfache Wartung bei großer Abscheidung zu ermöglichen, kann ein entfernbares Innenrohr aus nichtrostendem Stahl passgenau in das Abscheiderohr eingeschoben werden. Bei Bedarf kann das Innenrohr entnommen und gereinigt oder getauscht werden.To enable easy maintenance with large separation, a removable stainless steel inner tube can be inserted into the separator tube with an exact fit. If necessary, the inner tube can be removed and cleaned or replaced.
Um ein einfaches nachträgliches Aufsetzen auf die Schornsteinmündung zu ermöglichen, kann vorgesehen sein, dass der Elektrofilter stromaufwärts der Ionisierungskammer eine Montageplatte aufweist.In order to enable a simple subsequent placement on the chimney muzzle, it can be provided that the electrostatic filter has a mounting plate upstream of the ionization chamber.
Turbulenzen und Verwirbelungen im Bereich der Filterelektrodenanordnung wirken sich vorteilhaft auf die Abscheideraten aus. Um Wirbel in der Abgasströmung zu initiieren, ohne den Durchfluss der Rauchgase zu behindern, ist es besonders vorteilhaft, wenn die Ionisationskammer im Übergangsbereich zum Einschubrohr und zum Abscheidebereich unstetig erweitert ist.Turbulence and turbulence in the area of the filter electrode arrangement have an advantageous effect on the deposition rates. In order to initiate eddies in the exhaust gas flow without obstructing the flow of the flue gases, it is particularly advantageous if the ionization chamber is expanded discontinuously in the transition region to the insertion tube and to the separation region.
Weiters kann vorgesehen sein, dass um den Abscheidebereich und um die Ionisationskammer ein elektrischer Isolator angeordnet ist.Furthermore, it can be provided that an electrical insulator is arranged around the separation area and around the ionization chamber.
In einer besonders einfachen Ausführungsvariante ist vorgesehen, dass die Ionisationskammer durch ein T-förmiges Rohr gebildet ist, wobei anschließend an den einmündenden Rohrteil des T-Rohres ein Hochspannungsgenerator angeordnet ist, der mit der Filterelektrodenanordnung und dem Abscheidebereich leitend verbunden ist.In a particularly simple embodiment variant, it is provided that the ionization chamber is formed by a T-shaped tube, wherein a high-voltage generator, which is conductively connected to the filter electrode arrangement and the deposition region, is subsequently arranged on the opening tube part of the T-tube.
