Description
Verdampfereinrichtung mit durch die Verdampferbrüden beheiztem Speisewasservorwärmer.Evaporator device with feed water preheater heated by the evaporator vapors.
Die Erfindung betrifft eine Verdampfereinrichtung mit durch die Verdampferbrüden beheiztem Speisewasservorwärmer. The invention relates to an evaporator device with through the evaporator vapors heated feed water preheater.
Nach der Erfindung wird die Verdampfung durch die Brüden eines Entspannungsbehälters bewirkt, dessen Wasserinhalt nebst dem Niederschlagswasser des Verdampferheizdampfes mittels einer Umwälzpumpe im Kreislauf durch eine Abgasverwertungseinrichtung, z. B. einen Rauchgasvorwärmer, gefördert und dabei erhitzt wird. Die Erfindung besteht also in der Vereinigung folgender an sich bekannter Einzelmerkmale a) zur Speisewasserverdampfung dienen die durch Nachverdampfung aus in stetem Kreislauf umgewälzten Niederschlagswasser erzeugten Brüden; b) dieses zur Brödenerzeugung dienende Niederschlagswasser wird durch Abgase beheizt, und c) die Anlage wird zur Speisewasseraufbereitung benutzt. According to the invention, the evaporation is carried out by the vapors of an expansion tank causes its water content along with the precipitation water of the evaporator heating steam by means of a circulating pump in the circuit through an exhaust gas recycling device, e.g. B. a flue gas preheater, is promoted and heated. The invention exists thus in the combination of the following individual features known per se a) for feed water evaporation are used by re-evaporation from rainwater that is circulated in a constant cycle generated vapors; b) this rainwater, which is used to generate soil, becomes heated by exhaust gases, and c) the system is used for feed water treatment.
Das unter a genannte Merkmal ist deshalb von besonderer Wichtigkeit, weil es eitlen störungsfreien Betrieb des Rauchgasvorwärmers gewährleistet, während bei Benutzung von Rohwasser infolge der in ihm vorhandenen Beimengungen diese Gewähr nicht vorhanden ist. The feature mentioned under a is therefore of particular importance, because it ensures vain trouble-free operation of the flue gas preheater while this guarantee when using raw water due to the admixtures present in it does not exist.
In der Zeichnung ist der Gegenstand der Erfindung beispielsweise schematisch dargestellt. In the drawing, the subject of the invention is for example shown schematically.
Bei dem gezeichneten Ausführungsbeispiel stellt 1 einen beliebigen Körper dar, welcher geeignet ist, Abgasen eines Kessels, einer Verbrennungskraftmaschine u. dgl. ausgesetzt zu werden, z. B. einen Rauchgasvorwärmer. In the illustrated embodiment, 1 represents any Body which is suitable for exhaust gases from a boiler, an internal combustion engine and the like to be exposed, e.g. B. a flue gas preheater.
Das in dem RauchgasvorwärmerI erhitzte Wasser wird durch eine Leitung 2 einem Behälter 3 zugeführt, in welchem es entspannt wird. Das in dem Behälter anfallende Wasser wird durch eine Pumpe 4 und eine Leitung 5 dem Rauchgasvorwärmer I wieder zugeführt. Der Brüdendampf wird durch eine Leitung 6 den Heizelementen (Schlangen) eines Verdampfers 7 (Mitteldruckverdampfer) zugeführt, und das Niederschlagswasser aus diesen Schlangen wird durch ein Rohr 8 wieder der Pumpe 4 zum Einspeisen in den Rauchgasvorwärmer zugeleitet. The water heated in the flue gas preheater I is fed through a pipe 2 fed to a container 3 in which it is relaxed. That in the container Accumulating water is fed through a pump 4 and a line 5 to the flue gas preheater I fed back. The exhaust steam is passed through a line 6 to the heating elements (Coils) of an evaporator 7 (medium pressure evaporator) are supplied, and the rainwater from these snakes is through a pipe 8 again the pump 4 for feeding into fed to the flue gas preheater.
Auf diese Weise entstehen zwei Kreisläufe 1-2-3-4-5-1 und 1-2-3-6-7-8-4-5-I. In this way, two cycles are created, 1-2-3-4-5-1 and 1-2-3-6-7-8-4-5-I.
Der Brüdendampf aus dem Verdampfer 7 wird zweckmäßig zum Betriebe eines zweiten Verdampfers 9 verwendet, indem er durch eine Leitung 10 den Schlangen dieses Verdampfers zugeführt wird. Die beiden Verdampfer7 und 9 sind erst bestimmt, das eigentliche Kesselspeisewasser zu erzeugen oder das Eindampfen von Lauge usw. vorzunehmen. Diese Verdampfer sind von bekannter Bauart und können leicht gereinigt werde, so daß hier die Unreinigkeiten des Rohwassers oder die Abscheidungen der Lauge keinen Schaden anzurichten vermögen. The exhaust vapor from the evaporator 7 is expedient for operation a second evaporator 9 is used by passing through a line 10 the coils this evaporator is fed. The two evaporators 7 and 9 are only determined to generate the actual boiler feed water or the evaporation of lye, etc. to undertake. These evaporators are of known design and can be cleaned easily so that here the impurities of the Raw water or the deposits the lye are unable to cause any damage.
Das Niederschlagswasser aus den Schlangen des Verdampfers g wird durch eine Leitung 11 einer Pumpe 12 zugeführt und durch diese in einen bekannten Mischvorwärmer I3 eingespeist. Der Brüdendampf aus dem Verdampfer 9 geht durch eine Leitung 14 ebenfalls in diesen Mischvorwärmer. Letzterer ist durch eine Leitung 15 an eine Luftpumpe angeschlossen, und durch eine Leitung I6 wird je nach dem Stand des Wasserspiegels in dem Mischvorwärmer Speisewasser eingespeist. Das vorgewärmte Wasser fließt durch eine Leitung I7 einer Pumpe I8 zu, welche dasselbe durch eine Leitung 19 der Verwendungsstelle zudriickt. Von der Leitung 19 oder der Pumpe 18 ist eine Leitung 20 abgezweigt, welche dieses gereinigte Wasser dem Behälter 3 zuführt, um es hier entsprechend dem Abgang durch Lässigkeitsverluste einzuspeisen. Auf diese Weise ist in den beiden vorgenannten Kreisläufen, deren Wasser durch den Vorwärmer wandert, nur vollständig gereinigtes und entlüftetes Wasser vorhanden, welches weder Anlaß zu Kesselsteinbildung an den Wanzungen der Innenräume des Vorwärmers noch zu einem Angriff dieser Wandungen bieten kann. The rainwater from the coils of the evaporator is g fed through a line 11 to a pump 12 and through this into a known one Mixing preheater I3 fed in. The exhaust vapor from the evaporator 9 goes through a Line 14 also in this mixer preheater. The latter is through a line 15 is connected to an air pump, and through a line I6, depending on the state of the water level in the mixing preheater feed water is fed. The preheated Water flows through a line I7 to a pump I8, which the same through a Line 19 of the point of use is closed. From line 19 or pump 18 a line 20 is branched off, which feeds this purified water to the container 3, in order to feed it in here according to the outlet due to leakage losses. To this Way is in the two aforementioned circuits, whose water through the preheater migrates, only completely purified and deaerated water available, which neither Still cause for scale formation on the bumps of the interior of the preheater can offer to attack these walls.
