Description
Die Erfindung betrifft eine Vorrichtung zur Erzeugung gereinigter Druckluft, bei der Luft in einem Luftverdichter verdichtet wird, die verdichtete Luft über eine Rohrleitung einer Reinigungseinrichtung zugeführt und dort gereinigt wird und bei dem aus der Reinigungsvorrichtung gereinigte Luft abgezogen wird.The The invention relates to a device for producing purified compressed air, is compressed in the air in an air compressor that compacted Air supplied via a pipe to a cleaning device and is cleaned there and in the case of the cleaning device cleaned air is withdrawn.
Die gereinigte Druckluft kann beispielsweise als Einsatzluft in einer Tieftemperatur-Luftzerlegungsanlage, aber auch für jeden anderen Zweck verwendet werden. Die Reinigungsvorrichtung wird üblicherweise adsorptiv betrieben und weist mindestens zwei umschaltbare Behälter mit Adsorptionsmittel, beispielsweise einem Molekularsieb, auf.The cleaned compressed air can be used, for example, as feed air in a Cryogenic air separation plant, but also for everyone be used for another purpose. The cleaning device is usually adsorptively operated and has at least two switchable container with adsorbent, such as a molecular sieve on.
Eine
derartige Vorrichtung ist aus
Der Erfindung liegt die Aufgabe zugrunde, eine derartige Vorrichtung mit besonders geringem apparativem Aufwand herzustellen.Of the Invention is based on the object, such a device produce with very little equipment.
Diese Aufgabe wird durch Mittel zum Eindüsen von Wasser in die Rohrleitung gelöst. Es wird also Wasser in die Rohrleitung zwischen Luftverdichter und Reinigungseinrichtung eingedüst. Das Eindüsen dient der Erzeugung feiner Wassertröpfchen und damit einer großen Oberfläche zum Wärme- und Stoffaustausch mit dem verdichteten Luftstrom.These Task is by means of injecting water into the Pipeline solved. So it gets water into the pipeline injected between air compressor and cleaning device. The injection serves to produce fine water droplets and thus a large surface area for heating and mass transfer with the compressed air stream.
Auf diese Weise wird die verdichtete Luft unmittelbar in der Rohrleitung durch direkten Wärmeaustausch mit dem eingedüsten Wasser abgekühlt. Ein separater Druckbehälter für den Direktkontaktkühler kann entfallen. Damit fallen geringere Investitionskosten an und die Anlage benötigt weniger Platz. Das erfindungsgemäße Verfahren kann bei einem mehrstufigen Luftverdichter auch den oder die Zwischenkühler des Verdichters ersetzen. "Luftverdichter" im Sinne des Patentanspruchs 1 ist dann die Verdichterstufe stromaufwärts der Wassereindüsung.On This way, the compressed air is directly in the pipeline by direct heat exchange with the injected Water cooled. A separate pressure vessel for the direct contact cooler can be omitted. In order to incur lower investment costs and the system requires less space. The inventive method In the case of a multistage air compressor, the intercooler (s) can also be used replace the compressor. "Air compressor" within the meaning of the claim 1 is then the compressor stage upstream of the water injection.
Die Rohrleitung, in die gemäß der Erfindung Wasser eingedüst wird, unterscheidet sich dadurch von einem Direktkontaktkühler oder ähnlichen Kühlvorrichtungen durch eine horizontale Strömungsrichtung, einen besonders niedrigen Querschnitt (Durchmesser beispielsweise 20 bis 200 cm, abhängig vom Durchsatz). Es wird kein separater Apparat zur Entfernung der Verdichtungswärme benötigt, insbesondere kein Rohrbündel oder Ähnliches.The Pipe, in accordance with the invention, water is thereby different from a direct contact cooler or similar cooling devices by a horizontal Flow direction, a particularly low cross-section (Diameter, for example, 20 to 200 cm, depending on throughput). There is no separate apparatus for removing the heat of compression requires, in particular no tube bundle or the like.
Vorzugsweise wird bei dem Betrieb der Vorrichtung nicht nur an einer Stelle, sondern an mindestens zwei Stellen, insbesondere an mindestens drei Stellen, insbesondere an mindestens vier Stellen der Rohrleitung Wasser eingedüst. Die Eindüse-Stellen sind nacheinander in Strömungsrichtung entlang der Rohrleitung angeordnet.Preferably in the operation of the device not only in one place, but at least two places, in particular at least three places, in particular at least four points of the pipeline injected water. The injection points are successively in the flow direction arranged along the pipeline.
Grundsätzlich funktioniert die erfindungsgemäße Vorrichtung mit jeder Art von Verteileinrichtung innerhalb der Rohrleitung, in vielen Fällen sogar ohne Verteileinrichtung. Es kann aber günstig sein, wenn einer Stelle der Wassereindüsung eine Packung in der Rohrleitung angeordnet ist. Dies erhöht die Austauschfläche und verbessert somit den Wärmeübergang. Die Packung kann beispielsweise durch Drahtgestrick oder durch jede Art geordneter Packung aus gewellten Metallblechen oder Kunststoff gebildet werden. Zum Beispiel ist hinter jeder Eindüse-Stelle eine derartige Packung angeordnet.in principle the device according to the invention works with any kind of distribution device inside the pipeline, in many cases even without distribution device. It can but be beneficial if a point of water injection a pack is placed in the pipeline. This increases the exchange surface and thus improves the heat transfer. The pack can be made by wire knitting or by any means Sort of ordered packing of corrugated metal sheets or plastic be formed. For example, behind each injection spot is one arranged such pack.
In einer weiteren Ausgestaltung der erfindungsgemäßen Vorrichtung ist stromaufwärts der Reinigungseinrichtung und stromabwärts der Wassereindüsung beziehungsweise der Packung eine Wasserabscheidevorrichtung angeordnet. Diese Maßnahme verhindert oder verringert den Wassereintrag in die Reinigungsvorrichtung. Die Wasserabscheidevorrichtung kann beispielsweise als Demister ausgebildet sein.In a further embodiment of the invention Device is upstream of the cleaning device and downstream of the water injection respectively the pack arranged a Wasserabscheidevorrichtung. This measure prevents or reduces the water entry into the cleaning device. The Wasserabscheidevorrichtung can, for example, as a demister be educated.
Die verdichtete Luft kann stromaufwärts oder stromabwärts der Wassereindüsung durch indirekten Wärmeaustausch mit einem Kühlmittel abgekühlt werden. Der erfindungsgemäßen Form der Vorkühlung der verdichteten Luft kann also ein Maschinennachkühler vorgeschaltet sein. Als Kühlmittel wird üblicherweise Wasser verwendet.The compressed air may be upstream or downstream the water injection by indirect heat exchange be cooled with a coolant. The inventive Form of pre-cooling of the compressed air can thus a Machine aftercooler upstream. As a coolant usually water is used.
Vorzugsweise wird die erfindungsgemäße Vorrichtung in einem Verfahren beziehungsweise einer Vorrichtung zur Tieftemperatur-Luftzerlegung eingesetzt indem zur Tieftemperatur-Luftzerlegung, bei dem gereinigte Druckluft nach dem Verfahren mindestens ein Teil der gereinigten Druckluft abgekühlt und einer Trennsäule zugeführt wird.Preferably the device according to the invention in a Method or a device for cryogenic air separation Used by the cryogenic air separation, in which purified Compressed air after the process at least part of the cleaned Cooled compressed air and fed to a separation column becomes.
