Description
Die Erfindung bezieht sich auf eine verbrennungstechnische oder elektrochemische Anlage mit Gebläse und Kondensatabführung.The invention relates to a combustion engineering or electrochemical plant with blower and condensate removal.
Bei verbrennungstechnischen oder elektrochemischen Anlagen, bei welchen wasserstoffhaltige Brenngase oder Brennstoffe reagieren, entsteht im Abgas Wasserdampf. Beim Abkühlen des Abgases kondensiert der Wasserdampf und Kondensat entsteht; letztgenanntes muss abgeführt werden. Die Kondensatleitung verfügt in der Regel über einen Siphon, um Abgasaustritt über die Kondensatleitung zu vermeiden.In combustion engineering or electrochemical plants in which hydrogen-containing fuel gases or fuels react, water vapor is formed in the exhaust gas. When cooling the exhaust gas condenses the water vapor and condensate is formed; the latter must be removed. The condensate line usually has a siphon to prevent exhaust gas leakage through the condensate line.
Häufig verfügen diese verbrennungstechnischen oder elektrochemischen Anlagen über ein Sauggebläse, welches die Reaktionsgase durch die Anlage saugen. Beispielsweise bei Brennstoffzellenanlagen wird ein vergleichsweise großer Unterdruck benötigt. Ist der Siphon stromauf des Sauggebläses, so ist eine entsprechend große Sperrhöhe des Siphons notwendig. Bei Brennstoffzellenheizgeräten gemäß dem Stand der Technik beträgt die Sperrhöhe mehr als 30 cm. Hierbei besteht das Problem, dass der Siphon zum Beispiel bei langen Betriebspausen austrocknen kann. Ist vergleichsweise wenig Kondensat im Siphon, so kann die Kondensatsäule dem Unterdruck nicht genügend Widerstand entgegen setzen; der Siphon wird leer gesaugt. Das Kondensat gelangt dabei in das Gebläse. Hierbei besteht das Problem, dass insbesondere dann, wenn der Druckstutzen des Gebläses nach oben mündet, das Kondensat unzureichend abgeführt wird und saures Kondensat im Gebläse verbleibt, welches einerseits das Gebläse angreift und andererseits über die Antriebswelle unkontrolliert nach außen gelangen kann, so dass auch der Antriebsmotor beschädigt werden kann.Frequently, these combustion engineering or electrochemical plants have a suction fan, which suck the reaction gases through the system. For example, in fuel cell systems, a comparatively large negative pressure is needed. If the siphon is upstream of the suction fan, a correspondingly large barrier height of the siphon is necessary. In prior art fuel cell heaters, the barrier height is more than 30 cm. The problem here is that the siphon may dry out during long periods of operation, for example. If there is comparatively little condensate in the siphon, the condensate column can not oppose the negative pressure sufficiently; the siphon is vacuumed empty. The condensate enters the blower. This consists the problem that, especially when the discharge nozzle of the blower opens up, the condensate is dissipated insufficient and acid condensate remains in the blower, which on the one hand attacks the blower and on the other hand can pass out uncontrollably via the drive shaft to the outside, so that the drive motor damaged can be.
Um dieses Problem zu lösen, werden häufig Schwimmerkondensatabscheider eingesetzt; diese sind jedoch schmutzanfällig, wodurch nach einer geraumen Betriebszeit häufig ein Dichtheitsprobleme auftritt und / oder kein Kondensat abfließt.Float condensate separators are often used to solve this problem; However, these are susceptible to dirt, which often occurs after a long operating time leakage problems and / or no condensate drains.
Der Erfindung liegt die Aufgabe zugrunde, bei einer verbrennungstechnischen oder elektrochemischen Anlage mit Gebläse und Kondensatabführung einen sicheren Betrieb zu gewährleisten.The invention has for its object to ensure a safe operation in a combustion engineering or electrochemical plant with blower and condensate drainage.
Diese Aufgabe wird durch eine Vorrichtung mit den Merkmalen des Anspruchs 1 dadurch gelöst, dass die Abgasleitung der verbrennungstechnischen oder elektrochemischen Anlage direkt oder über indirekt in das Gebläse mündet, wobei das Gebläse derart angeordnet ist, dass der Gebläseausgang horizontal oder nach unten erfolgt. Hierdurch kann Kondensat, das in das Gebläse fließt, auch wieder aus dem Gebläse abfließen.This object is achieved by a device having the features of
Vorteilhafte Ausgestaltungen ergeben sich durch die Merkmale der abhängigen Ansprüche.Advantageous embodiments result from the features of the dependent claims.
Ist die Kondensatabführung mit Siphon stromab des Gebläses angeordnet, so ergibt sich der Vorteil, dass der Siphon nicht ausgesaugt werden kann.If the condensate removal with siphon is arranged downstream of the blower, then there is the advantage that the siphon can not be sucked out.
Ist stromauf des Gebläses eine Kondensatneutralisierungseinheit angeordnet, wobei diese über kondensatneutralisierende Mittel in einem Auffangbehälter verfügt, so kann das saure Kondensat neutralisiert werden, so dass es die folgenden Aggregate nicht angreifen kann. Hierbei verfügt die Kondensatneutralisierungseinheit über einen Kondensatzulauf, über welchen das Kondensat von der verbrennungstechnischen oder elektrochemischen Anlage zufließt. Sie verfügt ferner über eine Kondensatabführung, die mit dem Gebläseingang verbunden ist.If a condensate neutralization unit is arranged upstream of the blower, this having a condensate neutralizing agent in a collecting container, the acidic Condensate can be neutralized so that it can not attack the following aggregates. In this case, the condensate neutralization unit has a condensate feed, via which the condensate flows from the combustion-technical or electrochemical plant. It also has a condensate drain, which is connected to the fan inlet.
Sind die Teile des Gebläses, insbesondere das Gehäuse und der Ventilator aus einem Kunststoff wie Polyamid oder Polyphenylensulfid hergestellt, so kann das Kondensat aufgrund seiner thermischen und chemischen Beständigkeit dieses Material wenig angreifen, insbesondere dann, wenn das Kondensat bereits vor dem Gebläse neutralisiert ist. Während herkömmlicherweise Gebläse aus Polyamid (PA) hergestellt werden, hat sich der Werkstoff Polyphenylensulfid (PPS) für die Erfindung als besonders vorteilhaft herausgestellt. Das Polyphenylensulfid kann hierbei auch glasfaserverstärkt verwendet werden.If the parts of the blower, in particular the housing and the fan made of a plastic such as polyamide or polyphenylene sulfide, the condensate can attack because of its thermal and chemical resistance of this material little, especially if the condensate is neutralized before the blower. While conventionally blowers made of polyamide (PA), the material polyphenylene sulfide (PPS) has been found to be particularly advantageous for the invention. The polyphenylene sulfide can also be used reinforced with glass fiber.
Ist ein Sicherheitstemperaturbegrenzer stromab der verbrennungstechnischen oder elektrochemischen Anlage angeordnet, so kann eine thermische Materialschädigung vermieden werden.If a safety temperature limiter is arranged downstream of the combustion-engineering or electrochemical plant, thermal damage to the material can be avoided.
Eine Abgasrückschlagklappe kann das Eindringen von Abgasen anderer Anlagen über eine gemeinsame Abgasableitung vermeiden.An exhaust gas check valve can prevent the ingress of exhaust gases of other systems via a common exhaust gas discharge.
Die Erfindung wird nun anhand der Figuren detailliert erläutert.The invention will now be explained in detail with reference to FIGS.
Hierbei zeigt die
Beim Betrieb strömt Abgas 3 aus der verbrennungstechnischen oder elektrochemischen Anlage durch die Abgasleitung 1 nach unten. Kondensat wird an dem Führungsblech 10 nach links unten geleitet, so dass das Kondensat in den Kondensatzulauf 2 des Auffangbehälters 4 tropft. Das Kondensat sammelt sich in dem Auffangbehälter 4 und wird dort von kondensatneutralisierenden Mitteln neutralisiert. Eine Labyrinthkörper 13 ist derart im Auffangbehälter 4 angeordnet, dass das Kondensat auf dem Weg zur Kondensatabführung 5 mehrfach umgelenkt wird. Zwischen Kondensatzulauf 2 und Kondensatabführung 5 erhebt sich der Labyrinthkörper 13 über das unterste Niveau der Verbindung zwischen Kondensatabführung 5 und Gebläseingang 11, so dass vom Kondensatzulauf 2 kein Kondensat direkt in das Gebläse 6 laufen kann, sondern stets durch den Auffangbehälters 4 innerhalb des Labyrinthkörpers 13 fließt. Das neutralisierte Kondensat fließt in den Gebläseeingang 11 und verliert dort horizontal betrachtet an Höhe. Der nicht weiter dargestellte Rotor des Gebläses 6 fördert das Kondensat zusammen mit dem Abgas horizontal nach rechts. Während das Abgas nach oben umgelenkt wird und nach oben durch die Abgasabführung 9 in die Umgebung entweicht, fließt das Kondensat stromab des Gebläses 6 durch die Kondensatleitung mit Kondensatsiphon 7.In operation, exhaust gas 3 flows from the combustion engineering or electrochemical plant through the
Die Erfindung ist nicht auf die beschriebene Ausführungsform begrenzt. So kann es sich bei der verbrennungstechnischen oder elektrochemischen Anlage um ein Brennwertheizgerät handeln. Der Gebläseausgang 12 kann in Strömungsrichtung nach unten geneigt sein, um den Kondensatabfluss zu fördern.The invention is not limited to the described embodiment. So it may be in the combustion engineering or electrochemical plant to a condensing boiler act. The
Optional kann ein oberhalb des Labyrinthkörpers 13 angeordneter Temperatursensor als Sicherheitstemperaturbegrenzer gewährleisten, dass es zu keiner Materialschädigung, insbesondere des Kunststoffs, bei Überhitzung kommt. Misst dieser Sensor eine Temperatur knapp unterhalb der Schmelztemperatur des Kunststoffs, so wird die verbrennungstechnische oder elektrochemische Anlage abgeschaltet.Optionally, a temperature sensor arranged above the
Ist die verbrennungstechnische oder elektrochemische Anlage nicht alleine an die Abgasabführung 9 angeschlossen, so besteht die Gefahr, dass Abgase dieser weiteren Anlagen über die gemeinsame Abgasabführung 9 in eine andere Anlage strömen. Dafür kann jeweils eine Abgasrückschlagklappe das Eindringen von Abgasen anderen Anlagen verhindern. Die Abgasrückschlagklappe kann stromab des Gebläses 6, zwischen Gebläse 6 und Kondensatneutralisierungseinheit 8 oder zwischen Labyrinthkörper 13 und Führungsblech 10 angeordnet sein.If the combustion-engineering or electrochemical plant is not connected to the exhaust-
