Description
A b w ä r m e n u t z u n gA w arm e u s u tio n
Verfahren und Vorrichtung zur Nutzung von Abwärmen, die auf unterschiedlichem Temperaturniveau anfallen.Method and device for the use of waste heat, which is based on different Incur temperature level.
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Nutzung von Abwärmen, die auf unterschiedlichem Temperaturniveau anfallen und teilweise von einem oder mehreren Kühlwasser,reisläufen aufgenommen werden.The invention relates to a method and a device for use of waste heat that occurs at different temperature levels and partially be absorbed by one or more cooling water, rice courses.
Zahlreiche Betreiber benötigen Dampf im unteren und mittleren Druckbereich.Numerous operators require steam in the lower and medium pressure range.
Meist ist gleichzeitig Ab wärme auf niedrigerem Niveau verfügbar, die hierfür gar nicht oder nur mit verhältnismäßig großem Aufwand, z.B. mit Wärmepumpen, genutzt werden könnte. Dabei sind oft erhebliche Investitionen und- auch hohe laufende Betriebskosten (zusätzlicher Strombedarf) zu erwarten.In most cases, waste heat is available at a lower level at the same time, which do not do this at all or only with relatively great effort, e.g. with heat pumps, could be used. There are often considerable investments and high ongoing investments Operating costs (additional electricity demand) to be expected.
Der Erfindung liegt die Aufgabe zugrunde, unter bestinmten Voraussetzungen dieses Problem einfach und mit nur sehr geringem Strombedarf zu lösen.The invention is based on the object under certain conditions to solve this problem easily and with very little power consumption.
Die Lösung ist den Ansprüchell zu entnehmen d wird nachstehend am Beispiel der Ausnutzung der Niedertemperaturabwärmen eines Dieselmotors für die Erzeugung von 3 bar-Dampf anhand des beiliegenden Schaltschemas stichwortartig erläutert.The solution is to be found in the claims Example of the exploitation of the Low-temperature waste heating of a diesel engine for the generation of 3 bar steam based on the enclosed circuit diagram explained.
Die Verwendbarkeit dieses Verfahrens ist jedoch nicht auf die Ausnutzung von Motorabwärmen beschränkt. Ausserdem sind auch Ausführungen mit anderen Stufenzahlen möglich.The usefulness of this method, however, is not due to its exploitation limited by engine waste heat. There are also versions with other numbers of steps possible.
Gemäss dem beiliegenden Schaltschema werden die Niedertemperaturabwärmen des Motors aus Zylinderkühlwasser, Ladeluft und Schmieröl von einem Kühlkreislauf über die Wärmetauscher 1 bis 3 aufgenommen. Das erhitzte Wasser wird anschliessend über die Entspanner 4 bis 6 stufenweise entspannt. Das restliche Wasser wird mittels Pumpe 16 zum Kondensat-Behälter 12 und von dort L'ber Pumpe 14 wieder in den Kreislauf gefördert. Der in den Entspannern 4 bis 6 gebildete Dampf wird von den Ejektoren 7 bis 9 angesaugt.According to the enclosed circuit diagram, the low-temperature waste heats of the engine from cylinder cooling water, charge air and lubricating oil from a cooling circuit added via the heat exchangers 1 to 3. The heated water is then Relaxed gradually via the relaxer 4 to 6. The remaining water is by means of Pump 16 to the condensate container 12 and from there via pump 14 back into the circuit promoted. The steam formed in the expanders 4 to 6 is released from the ejectors 7 to 9 sucked in.
Dic Ejektoren erhalten ihren Treibdampf aus dem Abgaskessel 11 des im Schema nicht dargestellten Dieselir.otors.The ejectors receive their motive steam from the exhaust gas boiler 11 of the Dieselir.otors not shown in the scheme.
Auf der Austrittsseite des Ejektors'9 fällt 3 bar-Dampf an, der neben der Wärme des Abgaskessels auch die wesentlichen N iedertemperatur-Abwärmon enthält.On the outlet side of the ejector'9 3 bar steam falls, the next the heat of the exhaust gas boiler also contains the essential low-temperature waste heat.
Dieser Dampf wird dem Wärmeverbraucher 10 der Fabrik zugeführt. Das dort anfallende Kondensat wird mittels Pumpe 13 ebenfalls dem Kondensatbehälter 12 zugeführt.This steam is fed to the heat consumer 10 of the factory. That Any condensate produced there is also transferred to the condensate container by means of pump 13 12 supplied.
Von dort e-folgt ber eine Pumpe 15 die Speisung des Abgaskessels 11.From there, the exhaust gas boiler 11 is fed via a pump 15.
Falls das Kondensat der Wärmeverbraucher 10 höhere Temperaturen aufweist, ist eine Einspeisung direkt;in den Entspanner 4 oder 5 sinnvoll.If the condensate of the heat consumer 10 has higher temperatures, is a direct feed; in the expander 4 or 5 makes sense.
Die Deckung der Kreislaufverluste erfolgt mit Zusatzwasser über Pumpe 17 Die genannten Dampfdrücke und Anwendungen sind nur beispielhaft zu verstehen. Die Anlage ist nach den Erfordernissen des Einzelfalles jeweils zu optimieren.The circuit losses are covered with make-up water via a pump 17 The steam pressures and applications mentioned are only to be understood as examples. The system must be optimized according to the requirements of the individual case.
