Description
Verdichter mit nachgeschalteter Turbine für Luft- oder Gasaufbereitungsanlagen Für Luft- und Gasaufbereitungsanlagen oder in chemischen Betrieben wird oft die verdichtete Luft oder das Gas in einer Turhine zwecks Erreichung bestimmter tiefer Temperaturen oder zwecks Leistungsrückgewinnung entspannt. Im ersteren Fall muß oft die durch die Entspannung erzielbare Temperatursenkung mit Rücksicht auf eine erwünschte Entfeuchtung tiefer gewählt werden, als der Behaglichkeit entspricht, weshalb oft die so behandelte Luft nach der Entfeuchtung wieder aufgewärmt werden muß. Im zweiten Fall kann bei verhältnismäßig hohen Drücken die Temperatur nach der Turbine unter o° sinken, was unter Umständen Eisbildung und Störungen in der Turbine zur Folge hat. In diesem Falle also., wo der Hauptzweck Leistungsrückgewinnung und nicht die Erzielung einer bestimmten Endtemperatur ist, besteht ein Bedürfnis, die Lüft oder die Gase vor der Entspannungsturbine aufzuheizen.Compressor with downstream turbine for air or gas processing systems For air and gas treatment plants or in chemical plants, the compressed air or the gas in a turhine for the purpose of reaching certain deeper Temperatures or relaxed for the purpose of power recovery. In the former case, must often the temperature decrease that can be achieved through relaxation with regard to a Desired dehumidification can be selected lower than the level of comfort, which is why the air treated in this way is often warmed up again after dehumidification got to. In the second case, the temperature can decrease at relatively high pressures the turbine will sink below o °, which may cause ice formation and malfunctions in the The turbine. So in this case. Where the main purpose is power recovery and is not the achievement of a certain final temperature, there is a need to heat the air or the gases upstream of the expansion turbine.
Vorliegende Erfindung betrifft eine solche Heizung sowohl für den einen als auch für den anderen Fall und bezweckt, die Heizwärme dem Arbeitsvorgang selbst zu entziehen. Die Erfindung besteht darin, daß die Luft oder das Gas nach oder vor der Entspannungsturbine durch die Verdichtungswärme selbst aufgeheizt wird. Da bei verhältnismäßig hohem Verdichtungsgrad der Verdichter doch gekühlt werden müßte, ist es zweckmäßiger, diese Wärme nicht durch Kühlwasser unausgenutzt wegzunehmen, sondern gemäß der Erfindung dem Arbeitsvorgang zugute kommen zu lassen.The present invention relates to such a heater for both one as well as the other case and the purpose of the heating is to heat the work process to withdraw yourself. The invention consists in that the air or the gas after or before the expansion turbine is heated by the compression heat itself. Because the compressors are cooled at a relatively high degree of compression would have to, it is more appropriate not to take away this heat unused by cooling water, but according to the invention to benefit the work process.
. An Hand der Zeichnung sei die Erfindung näher erläutert.. The invention is explained in more detail with reference to the drawing.
Die Abb. i und z zeigen die beiden @erwähnten Anwendungsfälle. Die Abh. i zeigt eine Erwärmung nach und die Abb. a eine solche vor der Entspannungsturbine.Figs. I and z show the two @ mentioned use cases. the Dep. I shows heating after and Fig. A such before the expansion turbine.
In Abh. i handelt es sich um eine Luftaufbereitung mittels so genannter Luftkältemaschine; es ist i der Verdichter, welcher die Luft einem chemischen Apparat oder Kühler 2 zudrückt; hierauf wird die Luft in der Turbine 3 zwecks Temperatursenkung entspannt und zwecks Wasserausscheidung in den Ausscheider 5 gedrückt; 6 ist die Antriebsmaschine des Verdichters. Nachfolgend wird nun gemäß der Erfindung die Luft mittels Heizung 4. durch die Verdichtungswärme wieder aufgeheizt. Diese Heizung ist in irgendeiner Art in den Verdichter i verlegt, wodurch die Verdichterwärm.e ganz oder zum Teil ausgenutzt und dem Vorgang der Luftaufbereitung wieder zugeführt wird. Auf diese Art erreicht man gleichzeitig zwei Vorteile; einerseits wird nicht nur der Verdichter vor zu hohen Temperaturen geschützt, anderseits auf billigem Wege die Luft in gewünschter Weise nachgeheizt.In Abh. I it is an air treatment by means of so-called Air chiller; it is i the compressor which the air to a chemical apparatus or cooler 2 closes; thereupon the air in the turbine 3 for the purpose of lowering the temperature relaxed and pressed into the separator 5 for the purpose of water elimination; 6 is the Driving machine of the compressor. Following is now the air according to the invention by means of a heater 4. heated up again by the heat of compression. This heater is relocated in some way to the compressor i, whereby the compressor heat.e fully or partially used and fed back into the air treatment process will. In this way one achieves two advantages at the same time; one hand will not only the compressor protected from excessively high temperatures, on the other hand on cheap Ways the air is reheated in the desired manner.
In Abb, z findet die Erwärmung der Luft vor der Entspannung in der Entspannungsturbine statt. i ist wieder der Verdichter, welcher die Luft dem Kühler z zudrückt; zwecks Rückgewinnung der vom Verdichter aufgebrachten Druckenergie wird die Luft in der Turbine 3 entspannt, wobei gemäß der Erfindung die entfeuchtete Luft vor der Entspannung durch die Verdichtungswärme . des Verdichters aufgeheizt wird. In diesem Fall überwiegt also nicht die Entfeuchtung der Luft, sondern die Rückgewinnung der vom Verdichter aufgewendeten Leistung. Eine Eisbildung in der Turbine und Störungen werden vollständig vermieden, und die Vorwärmung gestattet die Ausnutzung eines größeren Druckgefälles in der Entspannungsturbine.In Fig, z the warming of the air takes place before the relaxation in the Relaxation turbine instead. i is again the compressor, which the air to the cooler z pushes; for the purpose of recovering the pressure energy applied by the compressor the air in the turbine 3 is relaxed, the dehumidified according to the invention Air before relaxation due to the heat of compression. of the compressor is heated up will. In this case, it is not the dehumidification of the air that predominates, but the Recovery of the power used by the compressor. Ice formation in the Turbine and malfunctions are completely avoided and preheating is permitted the utilization of a larger pressure drop in the expansion turbine.
Die bei Kältemaschinen und Luftaufbereitungsanla,gen in üblicher Weise vorgesehenen Regelungs- und Steuereinrichtungen können in vorteilhafter Weise auch in den vorliegenden Anlagen angeordnet werden.The conditions in the usual way for refrigeration machines and air conditioning systems provided regulation and control devices can also in an advantageous manner be arranged in the present systems.
