Abstract

Die vorliegende Erfindung betrifft eine Einrichtung zum Abgasen eines explosiblen Gases über einen auf einem Dach eines Gebäudes angeordneten Kamin, an dessen oberem freien Ende ein Abblasekopf vorgesehen ist, welcher aus mehreren vom Kamin aus sternförmig abgehenden Verteilerrohren besteht, die an ihrem freien Ende jeweils mit einer Austrittsöffnung versehen sind. Um auch bei widrigen Windverhältnissen die bei einer Explosion ausgeübte Druckwellenbelastung zu verringern, sind die Endbereiche der Verteilerrohre als Strahlpumpen ausgebildet, bei welchen das explosible Gas das Treibmedium ist, das die Umgebungsluft ansaugt.

Description

Einrichtung zum Abblasen eines explosiblen Gases
Die vorliegende Erfindung betrifft eine Einrichtung zum Abgasen eines explosiblen Gases über einen auf einem Dach eines Gebäudes angeordneten Kamin, an dessen oberem freien Ende ein Abblasekopf vorgesehen ist, welcher aus mehreren vom Kamin aus sternförmig abgehenden Verteilerrohren besteht, die an ihrem freien Ende jeweils mit einer Austrittsöffnung versehen sind.
Die Kühlung großer Generatoren in Kraftwerken erfolgt in der Regel mit Wasserstoff. Bei Betriebsstörungen muss dieser Wasserstoff möglichst schnell aus den Generatoren entfernt werden. Diese schnelle Entleerung erfolgt durch ein Abblasen des Wasserstoffs über dem Dach des Maschinenhauses in die Atmosphäre. Da Wasserstoff ein explosibles Gas ist, besteht beim Austreten in die Atmosphäre und bei der Durchmischung mit dem Atmosphärensauerstoff die Gefahr einer
Knallgasexplosion. Die sich vom Zündort oberhalb der Abblaseeinrichtung ausbreitende Druckwelle kann zu einer Beschädigung des Daches des Maschinenhauses führen, in dem sich die Generatoren befinden.
Um diese Druckwellenbelastung weitgehend zu reduzieren sind Einrichtung der Eingangs genannten Art vorgesehen. Eine derartige Einrichtung zum Abblasen eines explosiblen Gases ist z.B. DE 195 17 163 Al beschrieben.
Bei dieser bekannten Anordnung wird das austretende Gas in eine der Anzahl der Austrittsöffnungen entsprechende Anzahl von Gasstrahlen getrennt, die zumindest in ihrem zündfähigen Volumenbereichen räumlich voneinander getrennt sind. Die Gasstrahlen können somit nicht zusammen zünden, sodass die durch eine Explosion auftretende Druckwelle eine kleinere Amplitude aufweist. Dies gilt jedoch nicht bei starken Windverhältnissen. Bei starken Windverhältnissen können die zündfähigen räumlich voneinander getrennten Volumenbereiche wieder zu einem einzigen großen zündfähigen Volumenbereich zusammengeblasen werden.
Aufgabe der vorliegenden Erfindung ist es eine Einrichtung der Eingangs genannten Art anzugeben, bei der auch bei widrigen Windverhältnissen die bei einer Explosion ausgeübte Druckwellenbelastung reduziert ist.
Diese Aufgabe wird erfindungsgemäß bei der Eingangs genannten Einrichtung dadurch gelöst, dass die Endbereiche der Verteilerrohre als Strahlpumpen ausgebildet sind, bei welchen das explosible Gas das Treibermedium ist, das die Umgebungsluft ansaugt.
Bei der erfindungsgemäßen Einrichtung wird die mittlere Dichte im ausgeblasenen Strahl erhöht, wodurch der Strahlimpuls größer ist. Die Erhöhung der mittleren Dichte ergibt sich aus der Tatsache, dass Luft ungefähr die 10-fache Dichte von Wasserstoff aufweist. Auf diese Weise werden die zündfähigen Volumina verkleinert und durch den großen Strahlimpuls kommt es zu keiner großen Ablenkung bei starken Windaufkommen.
Weitere zweckmäßige Ausgestaltungen der vorliegenden Erfindung ergeben sich aus den Unteransprüchen sowie aus der nachfolgenden Beschreibung eines Ausführungsbeispiels anhand der beigefügten Zeichnung.
In der Zeichnung zeigen:
Figur 1 eine schematische Seitenansicht einer erfindungsgemäßen Einrichtung zum Abblasen eines explosiblen Gases, Figur 2 eine Draufsicht auf die in Figur 1 dargestellte Einrichtung, und
Figur 3 einen Längsschnitt durch eine Strahlpumpe der erfindungsgemäßen Einrichtung.
Figur 1 zeigt eine Seitenansicht einer erfindungsgemäßen Einrichtung zum Abblasen eines explosiblen Gases, welche im Wesentlichen aus einem Kamin 2 und einem Abblasekopf 3 besteht, wobei der Kamin auf einem Dach 1 montiert ist.
Bei der erfindungsgemäßen Einrichtung ist der Abblasekopf 3 derart aufgebaut, das die Verteilerrohre in zwei Ebenen aufgeteilt sind. In der unteren Ebene befinden sich die Verteilerrohre 4 und in der oberen Ebene befinden sich die Verteilerrohre 5.
Um eine noch größere Trennung der ausgeblasenen explosiblen Gasgemischstrahlen zu erreichen sind die Verteilerrohre der oberen Ebene um einen vorgegebenen Winkel nach oben geneigt weiterhin sind die Verteilerrohre 4 und 5 alternierend angeordnet .
Am Ende der Verteilerrohre befindet sich erfindungemäß jeweils eine Strahlpumpe 6.
Der Aufbau der Strahlenpumpe 6 ist schematisch in Figur 3 dargestellt .
Mit 4, 5 ist das jeweilige Verteilerrohr dargestellt über welches das Wasserstoffgas G zugeführt wird. Am Ende des jeweiligen Verteilerrohres befindet sich die Treibdüse 8. In die davorliegenden Mischkammer 9 wird die Luft aufgrund des im Diffusorhals entstehenden Unterdrucks eingesaugt. Das gas vermischt sich im Wesentlichen im Diffusor 11 mit der angesaugten Luft bis zur Austrittsöffnung 7, durch welche es ausgeblasen wird. Mit αo und αu sind jeweils die Abstrahlwinkel des Luftgasgemisches gekennzeichnet, ß bezeichnet den Neigungswinkel der oberen Verteilerrohre 5. Aus der Figur 1 ist deutlich zu erkennen, dass durch die Neigung der oberen Verteilerrohre 5 um einen vorgegebenen Winkel nach oben die zündfähigen Volumina, die sich innerhalb der Abstrahlwinkel befinden, noch weiter voneinander getrennt sind.
