Description
Verfahren zur Verdampfung von Kesselspeisewasser.Process for evaporation of boiler feed water.
Die Erfindung betrifft ein Verfahren zur Verdampfung von Kesselspeisewasser, bei welchem die Verdampfungswärme dem warmen Kühlwasser des Maschinenkondensators entzogen wird und die unter Vakuum gebildeten Dämpfe in einem Hilfskondensator niedergeschlagen werden. Bei diesem bekannten Verfahren erfolgte die Kühlung dieses Hilfskondensators bisher mit dem kalten Kühlwasser der Hauptkondensation. Dieses Mittel ist aber nicht wirtschaftlich, weil bei einem derartigen Betriebe einerseits die zur Durchführung der Verdampfung erforderlichen Temperaturunterschiede nicht erreicht werden, anderseits das Kondensationskühlwasser vor dem Eintritt in den Hauptkondensator unzulässigenveise erwärmt wird und dadurch eine Verschlechterung des Vakuums des Hauptkondensators bedingt ist. The invention relates to a method for the evaporation of boiler feed water, at which the heat of evaporation is transferred to the warm cooling water of the machine condenser is removed and the vapors formed under vacuum are deposited in an auxiliary condenser will. In this known method, this auxiliary capacitor was cooled previously with the cold cooling water of the main condensation. This middle but it is not economical, because on the one hand the temperature differences required to carry out the evaporation are not reached on the other hand, the condensation cooling water before entering the main condenser is heated inadmissibly and thereby a deterioration in the vacuum of the Main capacitor is conditional.
Die Erfindung besteht darin, daß der Hilfskondensator in einem besonderen Kühlwasserstromkreis mit besonders tief gekühltem Wasser geschaltet ist. The invention consists in that the auxiliary capacitor in a special The cooling water circuit is switched with particularly deeply cooled water.
Zur Durchführung des neuen Verfahrens geeignete Vorrichtungen sind auf der Zeichnung dargestellt, und zwar zeigen Abb. I den Verdampfer mit dem Hilfskondensator in einfachen Linien; Abb. 2 eine Schauliniendarstellung der nach dem neuen Verfahren arbeitenden Anlage; Abb. 3 die Gesamtdarstellung der Anlage in einfachen Linien. Suitable devices for carrying out the new method are shown on the drawing, namely Fig. I show the evaporator with the auxiliary condenser in simple lines; Fig. 2 shows a visual line representation of the according to the new process working plant; Fig. 3 the overall representation of the system in simple lines.
Nach Abb. I ist der das zu verdampfende Rohwasser enthaltende Verdampfer 7 von einem Behälter 8 umgeben, der von dem warmen Kühlwasser des Maschinenkondensators durchflossen wird. Die im Verdampfer gebildeten Dämpfe werden nach einem Hilfskondensator 10 abgesaugt, aus welchem durch die Pumpe 13 die nicht niederschlagbaren Gase abgesaugt werden und durch die Leitung 12 das Destillat entnommen wird. Der Kondensator 10 wird durch Kühlwasser, welches den Kondensatorbehälter II durchfließt, gekühlt. Sofern zwischen dem Verdampfer 7 und dem Hilfskondensator 10 ein ausreichender Temperaturunterschied besteht, muß im Verdampfer 7 die Verdampfung einsetzen, ohne daß es erforderlich ist, zwischen Verdampfer und Kondensator einen Exhaustor 9, wie er in Abb. I dargestellt ist, anzuordnen. According to Fig. I is the evaporator containing the raw water to be evaporated 7 surrounded by a container 8, which is of the warm cooling water of the machine condenser is traversed. The vapors formed in the evaporator are after an auxiliary condenser 10 sucked, from which sucked by the pump 13, the non-precipitable gases and the distillate is removed through line 12. The capacitor 10 is cooled by cooling water which flows through the condenser tank II. Provided that there is a sufficient temperature difference between the evaporator 7 and the auxiliary condenser 10 exists, the evaporation must start in the evaporator 7 without it being necessary is, an exhaustor 9 between the evaporator and condenser, as shown in Fig. I. is to be ordered.
Ein ausreichender Temperaturunterschied läßt sich schaffen, wenn der Verdampfer nach Abb. 3, wo er mit 15 bezeichnet ist, im Hauptkühlwasserstromkreis, aber der dazu gehörige Hilfskondensator I9, gemäß der Erfindung, in einem besonderen Kühlwasserstromlçreis liegt, dessen Kühlwasser in dem Kühler 20 herabgekühlt wird. Die nicht niederschlagbaren Gase werden durch die Pumpe 22 fortgeschafft. Das Destillat wird durch die Pumpe 23 in den Kondensatraum des Hauptkondensators 17 geschafft und von hier aus zusammen mit dem Kondensat durch die Hauptkondensatpumpe 24 zum Kessel 25 gedrückt.A sufficient temperature difference can be created if the Evaporator according to Fig. 3, where it is denoted by 15, in the main cooling water circuit, but the associated auxiliary capacitor I9, according to the invention, in a special one Kühlwasserstromlçreis lies, the cooling water in the cooler 20 is cooled down. The gases that cannot be precipitated are carried away by the pump 22. The distillate is brought into the condensate space of the main condenser 17 by the pump 23 and from here together with the condensate through the main condensate pump 24 to the Kettle 25 pressed.
Diese Anordnung bietet folgende Vorteile. This arrangement offers the following advantages.
Der Kühler 20 kann mit geringerer Belastung als der Hauptkühler 14 betrieben werden, also mit hohem Wirkungsgrad, und kann demnach wesentlich kühleres Wasser als der Kühler I liefern. Daraus ergibt sich, daß in dem mit Kondensationskühlwasser betriebenen Verdampfer 15 eine höhere Temperatur als in dem Kondensator 19 herrschen wird, mit einem Temperaturunterschied, welcher die Verdampfung im Verdampfer 15 sicherstellt. Jedoch kann zwischen Verdampfer I5 und Hilfskondensator I9, wie in Abb. 3 dargestellt, ein Exhaustor I8 angebracht sein.The cooler 20 can have a lower load than the main cooler 14 be operated, i.e. with high efficiency, and can therefore be much cooler Water as the cooler I supply. It follows that in the one with condensation cooling water operated evaporator 15 a higher temperature than prevail in the condenser 19 is, with a temperature difference, which the evaporation in the evaporator 15 ensures. However, between evaporator I5 and auxiliary condenser I9, as in As shown in Fig. 3, an Exhaustor I8 should be attached.
In Abb. 2 ist der Verdampfer mit 7, der Hilfskondensator mit IO und seine Luftpumpe mit I3 bezeichnet. Der Exhaustor g kann fortbleiben. In Fig. 2 the evaporator is with 7, the auxiliary condenser with IO and his air pump is labeled I3. The Exhaustor g can remain.
Das neue Verfahren hat wesentliche Vorzüge. Da der Hilfskondensator aus dem Hauptkühlwasserstromkreis ausgeschaltet ist, so kann seine Kühlung keine Erwärmung des zum Hauptkondensator strömenden Kühlwassers bedingen, wie dies bei den bekannten Anlagen der Fall ist, wo das gesamte Kühlwasser zunächst den Vorkondensator und dann den Hauptkondensator durchströmt. The new process has significant advantages. Because the auxiliary capacitor is switched off from the main cooling water circuit, its cooling can not Heat the cooling water flowing to the main condenser, as in the case with the known systems, where all the cooling water first passes through the pre-condenser and then flows through the main capacitor.
Während bei diesen bekannten Anlagen die Destillaterzeugung nur eine geringe sein kann, weil sonst eine zu große Erwärmung des Kondensationskühlwassers eintritt, kann bei dem neuen Verfahren eine unbegrenzte Menge von Destillat erzeugt werden, denn je größer die Wärineentnahme aus dem Kühhvassersfromkreise der Hauptentnahme ist, um so günstiger wird das Vakuum des Hauptkondensators beeinflußt, und der Hilfskühler 20 kann so bemessen werden, daß das in ihm rückgekühlte Wasser die aus dem Hauptkondensationskühlwasserstromkreis entnommenen Wärmemengen aufnimmt, ohne daß der Destillationsvorgang, insbesondere der erforderliche Temperaturunterschied, zwischenVerdampfer und Hilfskondensator in Frage gestellt würde.While in these known plants the distillate production only one can be low, because otherwise the condensation cooling water will heat up too much occurs, the new process can produce an unlimited amount of distillate because the greater the heat extraction from the Kühhvassersfromkkreis the main extraction the more favorable the vacuum of the main condenser and the auxiliary cooler is affected 20 can be dimensioned so that the water recooled in it that from the main condensation cooling water circuit absorbs amounts of heat removed without the distillation process, in particular the required temperature difference between the evaporator and auxiliary condenser would be questioned.
