Description

Einrichtung zur Ausnutzung der Kühlwasserwärme von Brennkraftmaschinen. Bei Brennkraftmasehinenanlagen ist es wichtig, eine bestimmte niedrige Kühlwassertemperatur einzuhalten. Man hat zwar für Brenmkraftmaschinen schon vorgeschlagen, den Kühlwassermantel des Zylinders unter Unterdruck, der z. B. durch eine Luftpumpe erzeugt wird, zu setzen, um dadurch eine Verdampfung des Kühlwassers herbeizuführen, wobei die Verdampfungstemperatur des Kühlwassers dem erzeugtem: Unterdruck entspricht. Dieses Verfahren. erfordert jedoch neben der als Verlust eintretenden mechanischem Pumpenleistung gleichfalls in. Verlust geratene Kühlwassermengen für die Niedersc'hlagung des erzeugten kühlenden Dampfes.Device for utilizing the cooling water heat from internal combustion engines. In internal combustion engine systems, it is important to have a certain low cooling water temperature to be observed. It is true that the cooling water jacket has already been proposed for internal combustion engines of the cylinder under negative pressure, the z. B. generated by an air pump, too set to thereby cause evaporation of the cooling water, the evaporation temperature of the cooling water corresponds to the generated: negative pressure. This method. requires however, in addition to the mechanical pumping power which occurs as a loss in. Loss of cooling water quantities for the cooling down of the generated cooling Steam.

Die vorliegende Erfindung besteht nun in einer Einrichtung, welche den Vorteil, die Kühltemperatur auf der gewünschten niedrigen und konstanten Höhe zu erhalten, mit dem weiteren Vorteil vereinigt, da.ß die in das Kühlwasser der Maschine übergegangene Wärme, die sonst wegen der niedrigen Temperatur für Kraftzwecke .nicht verwendbar ist, für solche ausgenutzt wird, indem in .die Dampfleitung eine Kraftmaschine, 'z. B. eine Niederdruckkolbenmaschine oder eine Niederdrucktampfturbine oder der Niederdruckteil einer Dampfturbine, eingeschaltet wird.The present invention now resides in a device which the advantage of keeping the cooling temperature at the desired low and constant level to obtain, combined with the further advantage that the in the cooling water of the Machine transferred heat, which is otherwise for power purposes because of the low temperature .not usable, is used for such purposes by inserting a Engine, 'e.g. B. a low pressure piston engine or a low pressure steam turbine or the low pressure part of a steam turbine is switched on.

Eine besondere vorteilhafte Ausführungsform der Einrichtung wird dadurch erhalten, daß der unter Unterdruck erzeugte Kühlwasserdampf durch einen überhitzer, welcher von den Abgasen der Brennkraftmaschinen beheizt wird, hindurchgeleitet wird.A particularly advantageous embodiment of the device is thereby obtained that the cooling water vapor generated under negative pressure by a superheater, which is heated by the exhaust gases of the internal combustion engines, is passed through.

In einer Ausführungsform ist der Erfindungsgegenstand schematisch in der Zeichnung veranschaulicht. Der KüMwassermantel der Brennkraftmaschine steht durch die weite Rohrleitung b mit einem Behälter c in Verbindung. In diesem Behälter sammelt sieh der Dampf, der durch die von den Wandungen des Brennkraftzylinders hindurchgehende Wärme erzeugt wird. Dieser Dampf wird durch einen überhitzer d geleitet, der in dem Abgasstrom der Brennkraftmaschine eingeschaltet ist. In der Abbildung ist beispielsweise der überhitxer d hinter einem zweiten überhitzer e geschaltet, der den von einem durch die Abgase der Brennkraftmaschine im Dampfkessel ferzeugten Hochdruckdampf überhitzt. Der überhitzte Niederdruckdampf wird bei g z. B. m eine Stufe einer Dampfturbine h geleitet. Durch geeignete bekannte Mittel kann der Druck vor Eintritt in diese Stufe für alle Belastungen konstant gehalten werden, trotzdem in der Stufe selber der Eintrittsdruck mit der Belastung wegfällt. Das aus den Oberflächenkondensatori geförderte Kondensat wird durch einen Wärmeaustauschapparat l hindurchgedrückt, indem die den Dampfkessel f verlassenden Abgase das Kondensat annähernd auf die Kühlwassertemperatur im Mantel der Brennkraftmaschine erwärmen und es bei m wieder in den Behälter.c treten lassen.In one embodiment, the subject matter of the invention is schematic illustrated in the drawing. The KüMwasserkantel the internal combustion engine is in communication with a container c through the wide pipeline b. In this The container collects the steam that flows through the walls of the internal combustion cylinder passing heat is generated. This steam is passed through a superheater d, which is switched on in the exhaust gas flow of the internal combustion engine. In the picture For example, if the superheater d is connected after a second superheater e, of the ferzeugten by one through the exhaust gases of the internal combustion engine in the steam boiler High pressure steam overheated. The superheated low pressure steam is at g z. B. m a Stage of a steam turbine passed h. By suitable known means, the pressure must be kept constant for all loads before entering this stage, nevertheless In the stage itself, the inlet pressure drops with the load. That from the surface capacitors conveyed condensate is pressed through a heat exchanger l, by the exhaust gases leaving the steam boiler f the condensate approximately on the Heat the cooling water temperature in the jacket of the internal combustion engine and return it at m let it step into the container c.
