Description
Vorrichtung zum Verringern des Verschleißes von Gebläserädern der Saugzuggebläse, z. B. von Kondenslokomotiven Iss ist bekannt, in die Rauchkarninern, z. B. von Lokomotiven, Lenk- oder Prallbleche einzubauen zum Zwecke, die durch den Rauchgasstrom mitgerissenen Asche-, Zunder- oder Kohleteilchen, die sogenannte Lösche, aus dem Rauchgasstrom auszuscheiden. Auch ist es nicht mehr neu, hierbei die angesammelten Verbrennungsrückstände durch eine Ejektoranlage dem Feuerraum wieder zuzuführen.Device for reducing the wear and tear of fan wheels Induced draft fan, e.g. B. from condensate locomotives Iss is known to be in the Rauchkarninern, z. B. to install locomotives, steering or baffle plates for the purpose of the Flue gas stream entrained ash, scale or coal particles, the so-called extinguishing, to be eliminated from the flue gas flow. It is also no longer new, here the accumulated Return combustion residues to the combustion chamber through an ejector system.
Bei den Saugzuggebläsen von Kondenslokomotiven, auf die sich die Erfindung insbesondere bezieht, ist es von großer Bedeutung, den Rauchgasstrom von allen festen Bestandteilen der Rauchgase zu reinigen, weil durch diese Teilchen, die zusammen mit dem Rauchgasstrom durch das Gebläserad des Saugzuggebläses abgesaugt werden, es also durchströmen, ein so starker Verschleiß der Flügel des Gebläserades eintritt, daß die Wirtschaftlichkeit der Anlage in Frage gestellt ist. Zur Verringerung des Verschleißes derartiger Gebläseräder sind bereits Vorrichtungen mit dem Gebläse vorgeschalteten, beispielsweise in der Lokomotivrauchkammer angeordneten, aus Prall- und Lenkblechen bestehenden Abscheidern bekannt, durch die die von den Rauchgasen mitgerissenen Verbrennungsrückstände abgeschieden werden, so daß durch das Gebläse nur weitgehend gereinigte Rauchgase hindurchgehen.In the case of the induced draft fans of condensate engines, to which the invention is based in particular, it is of great importance to solidify the flue gas flow from all Components of the flue gases to be cleaned because by these particles that come together are extracted with the flue gas flow through the fan wheel of the induced draft fan, so flow through it when the blades of the fan wheel are so badly worn, that the profitability of the plant is in question. To reduce the Wear and tear of such fan wheels are already devices with the fan upstream, for example arranged in the locomotive smoke chamber, made of impact and baffles existing separators known, through which the smoke gases entrained combustion residues are separated, so that by the fan only largely purified smoke gases pass through.
Gemäß der Erfindung werden die in einen Sammelramm, z. B. den Boden der Lokomotivrauchkammer, abgeschiedenen Verbrennungsrückstände mit Hilfe eines durch Dampf oder Luft betriebenen Ejektors aus diesem Sammelraum abgesaugt und dem Rauchgasstroin im Schornstein hinter dem Gebläserad wieder zugeleitet. Durch die Wiederzuführung der Verbrennungsrückstände hinter dem Gebläserad wird der Vorteil erreicht, daß das Gebläserad selbst nur von Rauchgasen durchströmt wird, die keine festen Bestandteile mehr enthalten.According to the invention, the in a collecting ram, for. B. the floor the locomotive smoke chamber, separated combustion residues with the help of a sucked by steam or air operated ejector from this collecting space and the Flue gas fed back into the chimney behind the fan wheel. Through the The return of the combustion residues behind the fan wheel will be the advantage achieved that the impeller itself is only flowed through by smoke gases, which are none contain more solid components.
An Stelle der Ejektoranlage ist es auch möglich, die Beförderung der Verbrennungsrückstände auf mechanischem Wege, z. B. durch eine Schnecke, oder aber durch die beiden angegebenen Mittel in Nacheinanderschaltung umzuleiten. Es ist auch möglich, die Verbrennungsrückstände nicht in die Abgasleitung zum Schornstein, sondern in an sich bekannter Weise dem Feuerraum wieder zuzuführen, wo ein weiterer Auslirand dieser st@.rlr kAlebaltigen Teilrhen erfnl¢tInstead of the ejector system, it is also possible to transport the Combustion residues by mechanical means, e.g. B. by a snail, or else redirect through the two specified means in series. It is also possible, the combustion residues not in the exhaust pipe to the chimney, but to feed it back into the furnace in a manner known per se, where another Overshoot of these st @ .rlr callous partial rows required
