Abstract
Die Erfindung betrifft ein Verdichtungsverfahren, bei dem die Wirkprinzipien der Radial- und Axialverdichter in einer Prozessstufe ablaufen. Eine derartige technische Lösung wird in erster Linie im Bereich der Energiewirtschaft und im chemischen Anlagenbau benötigt. Bei der Verdichtung von Arbeitsfluid wird investive kinetische Energie durch verzögerte Strömung und Zentrifugalkraft in Druck umgewandelt. Die dabei entstehenden Verluste differieren je nach Bauart des Verdichters. In Abhängigkeit vom Massendurchsatz und dem benötigten Druckgefälle besitzen Radial- und Axialverdichter jeweils bauartbedingte Vorzüge. Axialverdichter arbeiten mit großen Durchsätzen bei relativ niedrigem Stufendruckgefälle, wogegen Radialverdichter bei geringeren Durchsätzen höhere Stufendruckgefälle erzielen. Das Entwicklungsniveau beider Verdichterarten ist sehr hoch. Dennoch fehlen besonders für kleinere und mittlere Anlagengrößen Verdichter, die zwischen dem Leistungsspektrum beider Verdichterarten liegen. Aufgabe der Erfindung ist, den Leistungsbereich abzudecken, der zwischen der effizienten Radial- und Axialverdichtung liegt.The invention relates to a compression method in which the active principles of the radial and axial compressors run in one process stage. Such a technical solution is needed primarily in the field of energy and chemical plant construction. In the compression of working fluid, kinetic energy is converted into pressure by delayed flow and centrifugal force. The resulting losses differ depending on the design of the compressor. Depending on the mass flow rate and the required pressure gradient, radial and axial compressors each have design-related advantages. Axial compressors operate at high flow rates at relatively low step pressure drop, whereas centrifugal compressors achieve higher step pressure drops at lower flow rates. The development level of both compressor types is very high. Nevertheless, especially for smaller and medium plant sizes compressors are missing, which lie between the power spectrum of both compressor types. The object of the invention is to cover the power range that lies between the efficient radial and axial compression.
Description
Die Erfindung betrifft ein Verdichtungsverfahren, bei dem die Wirkprinzipien der Radial- und Axialverdichter in einer Prozessstufe ablaufen. Eine derartige technische Lösung wird in erster Linie im Bereich der Energiewirtschaft und im chemischen Anlagenbau benötigt.The The invention relates to a compacting method in which the principles of action run the radial and axial compressor in a single process stage. Such a technical solution is primarily used in the energy and chemical sectors Plant construction needed.
Bei der Verdichtung von Arbeitsfluids wird investive kinetische Energie durch verzögerte Strömung und Zentrifugalkraft in Druck umgewandelt. Die dabei entstehenden Verluste differieren je nach Bauart des Verdichters. In Abhängigkeit vom Massendurchsatz und dem benötigten Druckgefälle besitzen Radial- und Axialverdichter jeweils bauartbedingte Vorzüge. Axialverdichter arbeiten mit großen Durchsätzen bei relativ niedrigem Stufendruckgefälle, wogegen Radialverdichter bei geringeren Durchsätzen höhere Stufendruckgefälle erzielen. Tendenziell verbessert sich die Verdichtungseffiziens mit zunehmender Größe der Turbomaschinen. Das Entwicklungsniveau beider Verdichterarten ist sehr hoch. Dennoch fehlen besonders für kleinere und mittlere Anlagengrößen Verdichter, die zwischen dem Leistungsspektrum beider Verdichterarten liegen.at the compression of working fluids becomes investive kinetic energy delayed by flow and centrifugal force converted into pressure. The resulting Losses differ depending on the design of the compressor. Dependent on from the mass flow rate and the required pressure drop have radial and axial compressor each design-related benefits. axial compressor work with big ones throughputs at relatively low step pressure gradient, whereas radial compressor achieve higher step pressure drops at lower flow rates. The compression efficiency tends to improve with increasing Size of turbomachinery. The development level of both compressor types is very high. Still missing especially for smaller and medium plant sizes compressors, which lie between the performance spectrum of both compressor types.
Es ist deshalb Aufgabe der Erfindung, den Leistungsbereich abzudecken, der zwischen der effizienten Radial- und Axialverdichtung liegt.It It is therefore an object of the invention to cover the power range, which lies between the efficient radial and axial compression.
