Abstract

The procedure for utilising industrial waste-heat to generate electric power is based on the availability of a source of waste-heat at temps. between +90 and +150 deg.C, and of a land feature between 20 and 400 m high. A heat exchanger (3) at the base of the feature uses the waste-heat to evaporate a working fluid. The vapour rises along a pipe (5), possibly heated, to drive a prime mover (6) coupled to a generator (7). It then passes through a water (8)-cooled condenser (1) at the feature's top into a return line (2), the static head overcoming the evaporator pressure-drop.

Description

INDUSTRIEABWÄRMEKRAFTWERK INDUSTRIAL HEAT POWER PLANT

Die Erfindung betrifft ein Verfahren zur Nutzung von Industrie-Abwärme zur elektrischen Energiegewinnung.The invention relates to a method for using industrial waste heat for electrical energy generation.

Es ist bekannt, daß große Mengen aller Arten von Industrie-Abwärme nutzlos verlorengehen. Der Erfindung liegt die Aufgabe zugrunde, diese Abwärme nutzbar zu machen. Maßgebend hierbei ist die richtige Wahl der Arbeitsmittel, die erfindungsgemäß von den örtlich vorliegenden Umständen abhängig ist. Daraus resultieren die mit den Beispielen gegebenen Möglichkeiten der erfindungsgemäßen Nutzung der Abwärmequellen. Die näheren Erläuterungen des Erfindungsgedankens werden mit den Beispielen gegeben.It is known that large amounts of all types of industrial waste heat uselessly lost. The invention is based on the object of utilizing this waste heat close. The decisive factor here is the correct choice of work equipment according to the invention depends on the local circumstances. This results in the with the examples given possibilities of using the waste heat sources according to the invention. The examples provide more detailed explanations of the concept of the invention.

Als Beispiel 1 - nach Figur 1 - liegt eine Abwärmequelle zwischen Temperaturen von mindest plus 90°C bis etwa 150°C, auch darüber, vor. Dabei ist allerdings die Voraussetzung, daß die Abwärmequelle in der Nähe eines Berges liegt. Wie aus Figur 1 ersichtlich, erfolgt die Verdampfung des Arbeitsmittels im Verdampfer (3) z.B. mit Dichlordifluormethan u.a. mit Fabriknamen Frigen bekannt, hier also Frigen 12, mittels der Abwärme. Die Dämpfe werden in (5) hochgeführt, gegebenenfalls wird diese Leitung etwas angeheizt. Die Dämpfe treiben eine Kraftmaschine (6) gekoppelt mit einem Stromerzeuger (7). Das Arbeitsmittel wird nun verflüssigt im Verflüssiger (1), mit Kühlwasser (8). Nun wird, das ist Voraussetzung einer realen Nutzung, die Fallhöhe zur statischen Überwindung des Verdampferdruckes verwendet. Damit ist der Kreislauf geschlossen.As an example 1 - according to Figure 1 - is a waste heat source between Temperatures of at least plus 90 ° C to about 150 ° C, also above, before. It is however, the prerequisite is that the waste heat source is close to a mountain. As can be seen from FIG. 1, the working medium is evaporated in the evaporator (3) e.g. known with dichlorodifluoromethane, among others with the factory name Frigen, so here Frigen 12, by means of the waste heat. The vapors are led up in (5), if necessary this line is heated up a bit. The vapors drive an engine (6) coupled with a power generator (7). The working fluid is now liquefied in the liquefier (1), with cooling water (8). Well, that is a requirement of a real use that Fall height used to statically overcome the evaporator pressure. So that is Closed circuit.

Als Beispiel 2 - Figur 2 - steht nicht die Nähe einer Anhöhe oder eines Berges zur Verfügung. Man wird hier mit größeren Mengen Arbeitsmittel arbeiten, z.B. mit Methylenchlorid-CH2Cl2- Sp. plus 41,8°C und eine geringere Fallhöhe erstellen um mit dem flüssigen Arbeitsmittel eine Kraftmaschine mit Stromerzeuger zu betreiben.As an example 2 - Figure 2 - is not the proximity of a hill or of a mountain available. One will work here with larger amounts of work equipment, E.g. with methylene chloride-CH2Cl2- Sp. plus 41.8 ° C and create a lower drop height in order to operate an engine with a power generator with the liquid working medium.

Die optimalen Bedingungen müssen wir in allen Beispielen errechnet werden und sind von den gegebenen Voraussetzungen abhängig.We have to calculate the optimal conditions in all examples are and are dependent on the given conditions.

Als Beispiel 3 - Figur 3 - ist das Zusammentreffen einer Geländeerhebung zur Abwärmequelle als Bedingung gegeben.Example 3 - Figure 3 - is the meeting of a terrain elevation given as a condition for the waste heat source.

Hier ist dann eine mehrfache erfindungsgemäße Nutzung wie diese in der Schemazeichung - Figur 3 - dargestellt wird, möglich. Diese erfindungsgemäße Arbeitsweise ist eindeutig mit Figur 3 gegeben.Here is then a multiple use according to the invention like this in the schematic drawing - Figure 3 - is shown, possible. This invention The mode of operation is clearly given in FIG. 3.

Im ersten Arbeitskreis wird z,l3 mit Frigen 12 nii t Sp minus 29,8°C als Arbeitsmittel eingesetzt. Mit der Abwärme des Frigen-12-Verdampfers wird ein weiterer Verdampfer mit dem Arbeitsmittel, z.l3. Frigen 22 - Sp. minus 40,8° C verwendet.In the first working group, z, l3 with Frigen 12 is nii t Sp minus 29.8 ° C used as work equipment. With the waste heat from the Frigen-12 evaporator, a further evaporator with the working medium, e.g. 13. Frigen 22 - Sp. Minus 40.8 ° C used.

Beide kreise arbeiten mit den Dämpfen der Arbeitsmittel zum Betreiben einer Kraftmaschine, gekoppelt mit Stromerzeuger.Both circles work with the vapors of the work equipment for operation an engine coupled with a power generator.

Die Fallhöhe dient hier wiederum zur Überwindung der Verdampferdrucke.The height of fall is used here in turn to overcome the evaporator pressures.

Zusätzlich kann das Kühlwasser der Verflüssiger beider Kreisläufe gesammelt werden und unter Nutzung der Fallhöhe gleichfalls eine Kraftmaschine, gekoppelt mit Stromerzeuger, betrieben werden. Daraus resultiert eine dreifache Nutzung.In addition, the cooling water can be used in the condenser of both circuits are collected and, using the height of fall, also a prime mover, coupled with a power generator. This results in a threefold Use.
