Description

Einrichtung zur Entfernung der Luft und des restlichen Dampfes aus Oberflächenkondensatoren Es ist bereits vorgeschlagen worden, das Absaugen der Luft aus Oberflächenkondensatoren mittels mehrstufiger Dampfstrahlapparate vorzunehmen und den Betriebsdampf der Strahlapparate in Mischkondensatoren niederzuschlagen. Bei der Verwendung von Mischkondensatoren trägt zwar das Niederschlagwasser des Betriebsdampfes des Strahlluftsaugers zur Vorwärmung des aus dem Kondensator entnommenen Kesselspeisewassers, das die einzelnen Stufen der Dampfstrahlapparate im Gleichstrom durchfließt, mit bei, da eine Mischung der beiden Kondensate verschiedener Herkunft stattfindet. In vielen Fällen muß man jedoch von der Verwendung eines solchen Mischkondensators zur Niederschlagung des Betriebsdampfes von Strahlluftsaugern absehen, weil wegen der unmittelbaren Verbindung der Turbine mit dem Wasserraum eines solchen Mischkondensators die Gefahr besteht, daß infolge von Druckänderungen Wasserschläge auftreten und dadurch Wasser in die Turbine gelangt. Es ist zwar bereits vorgeschlagen worden, zur Vermeidung dieses Nachteils das Niederschlagen des Betriebsdampfes eines Strahlluftsaugers in einem gleichzeitig als Speisewasservorwärmer dienenden Oberflächenwärmeaustauschapparat vorzunehmen; hierdurch würde aber, wenn das Niederschlagwasser aus dem Vorwärmer unmittelbar in die Saugleitung der Kondensatpumpe eingeführt wird, alsdann durch Abdrosselung des vorhandenen Druckunterschiedes zwischen dem Vorwärmer und dem Kondensator Dampfbildung eintreten und die entstandene Dampfmenge in den Kondensator zurückströmen, wo ihr Wärmeinhalt durch das Kühlwasser nutzlos abgeführtwird. Das aus dem Kondensator austretende Kondensat selbst könnte nämlich den sich bildenden Dampf nicht kondensieren, da es die gleiche Temperatur wie dieser besitzt.Device to remove the air and the remaining steam Surface capacitors It has already been suggested that the suction of the air from surface condensers using multi-stage steam jet devices and to condense the operating steam of the jet devices in mixing condensers. When using mixing condensers, the rainwater carries the Operating steam from the jet air extractor to preheat the steam extracted from the condenser Boiler feed water, which the individual stages of the steam jet apparatus in direct current flows through, because a mixture of the two condensates of different origins takes place. In many cases, however, one must avoid the use of such a mixing condenser refrain from suppressing the operating steam from jet air suction devices because of the direct connection of the turbine with the water space of such a mixing condenser there is a risk that water hammer will occur as a result of pressure changes and this causes water to enter the turbine. While it has already been suggested to avoid this disadvantage, the deposition of the operating steam of a jet air suction device in a surface heat exchange apparatus which also serves as a feedwater preheater to undertake; this would, however, if the rainwater from the preheater is introduced directly into the suction line of the condensate pump, then through Reduction of the existing pressure difference between the preheater and the condenser Steam formation occurs and the amount of steam generated flows back into the condenser, where their heat content is uselessly dissipated by the cooling water. That from the condenser escaping condensate itself could not condense the steam that forms, since it has the same temperature as this one.

Zur Vermeidung dieses Nachteils wird gemäß, der Erfindung bei einer Einrichtung zur Entfernung der Luft und des restlichen Dampfes bei Oberflächenkondensatoren mittels .eines ein- oder mehrstufigen Dampfstrahll.uftsaugers das Kondensat in an sich bekannter Weise aus dem Kondensator durch zwei hintereinandergeschaltete Röhrenvorwärmer geleitet, die im Gegenstrom hierzu vom Dampfluftgemisch des Strahlluftsaugers und dem Kondensat dieses Dampfes durchflossen w erden. Hierdurch ergibt sich der Vorteil, da.ß das Niederschlagwasser des Betriebsdampfes des Strahlluftsaugers in einem dem Wärmeaustauschapparat der ersten Stufe nachgeschalteten Wärmeaustauschapparat durch Wärmeabgabe an das durch die Kondensatpumpe aus dem Kondensator geförderte Kondensat auf eine Temperatur abgekühlt wird, die nur wenig über der Temperatur des letzteren liegt, -so daß, die in dem Niederschlagwasser des Strahlluftsaugers enthaltene Flüssigkeitswärme zum großen Teile zurückgewonnen wird, ohne daß eine Dampfbildung zu befürchten wäre.To avoid this disadvantage, according to the invention in a Device for removing the air and the remaining steam from surface condensers the condensate in. a single or multi-stage steam jet air extractor known way from the condenser through two series-connected tube preheaters guided in countercurrent to this by the steam-air mixture of the jet air suction device and the condensate of this steam flow through. This has the advantage da.ß the rainwater of the operating steam of the jet air extractor in one of the Heat exchange apparatus of the first stage downstream heat exchange apparatus Heat dissipation to the condensate pumped out of the condenser by the condensate pump on a temperature is cooled which is only slightly above the temperature of the latter is so that the liquid heat contained in the precipitation water of the jet air suction device to a large extent is recovered without fear of the formation of steam.

Der Erfindungsgegenstand ist in der Zeichnung in einem Ausführungsbeispiel veranschaulicht.The subject of the invention is shown in the drawing in one embodiment illustrated.

Der reit Frischdampf aus dem Kessel a betriebenen Kondensationsturbine b wird aus einer Niederdruckstufe Dampf zum Betriebe eines mit dem Kondensator e verbundenen Dampfstrahlluftsaugers d entnommen. Dieser Betriebsdampf wird in einem Röhrenkühlere niedergeschlagen und das Destillat durch einen D:estillatkühler f über einen Kondenstopf g der Saugleitung der Köndensatpumpe lz zugeführt. Diese Pumpe drückt das Xondensat zunächst durch den Kühler t und dann durch den Kühler,e der Kesselspeisepumpe i zu. Hierbei wird das Kondensat zunächst durch das in dem Kühler f abzukühlende Destillat .etwas :erwärmt und dann durch den kondensierenden Abdampf des Luftsaugers in dem Behälter ,e bis beispielsweise ioo° erhitzt, was dadurch möglich ist; daß infolge Verwendung von niedrig gespanntem Betriebsdampf für die Luftabsaugung große Mengen desselben verfügbar sind. Die in den Behälter e mit dem Betriebsdampf eingedrungene Luft tritt bei k aus diesem in die Atmo-, sphäre aus. Anstatt daß der Betriebsdampf für den Dampfstrahlluftsauger einer Kondensationsturbine entnommen wird, kann hierzu auch Abdampf einer Gegendruckmaschine, z. B. einer Antriebsmaschine für die Kondensationsmaschinen, Verwendung finden.The live steam rides from the boiler a operated condensation turbine b becomes steam from a low-pressure stage to operate one with the condenser e connected steam jet air extractor d removed. This operating steam is in one Tubular cooler knocked down and the distillate through a D: estillate cooler f is fed to the suction line of the condensate pump lz via a condensate trap g. These The pump first pushes the xondensate through the cooler t and then through the cooler, e the boiler feed pump i. Here, the condensate is first through the in the Cooler f distillate to be cooled. Somewhat: heated and then through the condensing Exhaust steam of the air suction in the container, e heated to, for example, ioo °, which this is possible; that as a result of the use of low-tension operating steam large quantities of the same are available for air extraction. The ones in the container e air that has penetrated with the operating steam exits at k into the atmosphere, sphere from. Instead of the operating steam for the steam jet air extractor of a condensation turbine is taken, this can also exhaust steam from a counter-pressure machine, z. B. a prime mover for the condensation machines.
