Abstract

Die Erfindung betrifft eine Abwärmenutzungsanlage für eine Abwärmequelle (10), bestehend aus einem dieser nachgeschalteten ORC (Organic-Rankine-Cycle), wobei die Abwärmequelle (10) mit der Beheizungsvorrichtung (8, 9) des ORC in Verbindung steht, sowie mit einer mit einem Generator (5) gekoppelten Expansionsmaschine (4) zur Dampfexpansion im ORC, wobei mindestens ein Verdampfer (3) mit einem nachgeschalteten Tropfenabscheider (12) gekoppelt ist, welcher im Wesentlichen aus einem liegend angeordneten zylindrischen Behälter (13) besteht, welcher einen Abscheideraum (14) einschließt, der in seinem unteren Bereich mindestens einen Dampfeintrittsstutzen (15) als Verbindung zum Verdampfer (3) und in seinem oberen Bereich mindestens einen Dampfaustrittsstutzen (16) aufweist. Es ist Aufgabe der Erfindung, den Betrieb einer Abwärmenutzungsanlage, im Wesentlichen bestehend aus einem einer Abwärmequelle nachgeschalteten ORC, durch einen optimierten Tropfenabscheider zu verbessern. Erfindungsgemäß ist daher der Tropfenabscheider (12) über die Wand des zylindrischen Behälters (13) von außen beheizbar, um eine Dampftrocknung zu erreichen.

The invention relates to a waste heat recovery system for a waste heat source (10) consisting of one of these downstream ORC (Organic Rankine cycle), wherein the waste heat source (10) with the heating device (8, 9) of the ORC is in communication, as well as with a A steam expansion machine (4) coupled to a generator (5) in the ORC, wherein at least one evaporator (3) is coupled to a downstream droplet separator (12) which essentially consists of a horizontally arranged cylindrical container (13) which forms a separation chamber (13). 14), which has in its lower region at least one steam inlet connection (15) as connection to the evaporator (3) and in its upper region at least one steam outlet connection (16). It is an object of the invention to improve the operation of a waste heat recovery system, consisting essentially of a downstream of a waste heat source ORC, by an optimized droplet. According to the invention, therefore, the mist eliminator (12) can be heated externally via the wall of the cylindrical container (13) in order to achieve steam drying.
