Abstract

Compressed air is dried by a system in which, heated by being compressed, it is precooled by the outgoing cold compressed air and then passes into a heat exchanger, which is integrated in a condensate separator/diverter. The compressed air is cooled below its dew pt. in an air cooler, condensate being separated and drained off in a condensate separator/diverter. The compressed air is then heated by the air entering in a superheater and then passers to the consumer. The entering air acts as frost protection for the condensate.

Description

Es ist bekannt, daß Druckluft-Trocknung bei Umgebungstemperaturen unter 2°C nicht bzw. nur beschränkt möglich ist, da die bisher bekannten Systeme nur bei Temperaturen über 2°C arbeiten. Es ist ferner bekannt, daß Druckluft-Trocknung ohne elektrische Energie nicht bzw. nur extrem beschränkt möglich ist.It is known that compressed air drying does not or does not occur at ambient temperatures below 2 ° C. is only possible to a limited extent, since the previously known systems only operate at temperatures above 2 ° C. work. It is also known that compressed air drying is not possible without electrical energy or is only possible to an extremely limited extent.

Der im Patentanspruch 1 angegebenen Erfindung liegt das Problem zugrunde, daß in bestimmten Anwendungen der Wirtschaft eine Druckluft-Trocknung in den frostgefährdeten Bereichen sowie in den Bereichen ohne elektrische Energie erforderlich machen.The invention specified in claim 1 is based on the problem that in certain Applications of the economy a compressed air drying in the frost-prone areas as well as in areas without electrical energy.

Diese Probleme werden durch die im Patentanspruch 1 aufgeführten Merkmale gelöst.These problems are solved by the features listed in claim 1.

Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß das Problem des Kondensatanfalls bei transportablen, benzin-/dieselbetriebenen Drucklufterzeugern (insbesondere auf Baustellen) weitgehend vermieden wird. Der Kondensatanfall führt teilweise zu Vereisungen in den Druckluftwerkzeugen. Des weiteren ist es jetzt auch möglich, Druckluft in Umgebungs­ temperaturen unter 2°C zu trocknen. In Kombination mit den bisher bekannten Systemen wie Kältetrockner stellt die Erfindung eine Lösung für den wirtschaftlichen Betrieb außerhalb ge­ schlossener Räume dar.The advantages achieved by the invention are in particular that the problem of Condensate accumulation in portable, gasoline / diesel powered compressed air generators (in particular on construction sites) is largely avoided. The accumulation of condensate sometimes leads to icing in the air tools. Furthermore, it is now also possible to use compressed air in the surrounding area to dry at temperatures below 2 ° C. In combination with the previously known systems such as Refrigeration dryer, the invention provides a solution for economic operation outside ge closed rooms.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben.An embodiment of the invention is shown in the drawing and is in the following described in more detail.

Die durch die Verdichtung erwärmte Druckluft tritt in den DL-Eintrittsstutzen ein, wird durch die austretende kalte Druckluft vorgekühlt (Pos. 3), tritt dann in den Wärmetauscher (Pos. 5), der im Kondensatabscheider/-ableiter (Pos. 2) integriert ist, ein. Diese somit vorgekühlte Druckluft tritt dann in den Druckluftkühler (Pos. 1) ein. Hier wird der Taupunkt der Druckluft unterschritten, dies führt zur Kondensatausscheidung, wobei der Luftkühler eine Neigung zum Druckluftaustrittszustand von 10% aufweist, damit das anfallende Kondensat in den Kondensatabscheider/-ableiter fließt. Die Druckluft tritt nach dem Druckluftkühler in den Kondensatabscheider/-ableiter (Pos. 2) ein, wo der Druckluftstrom in eine Rotationsbewegung mittels eines dafür eingesetzten Ablenkbleches versetzt wird und dabei die Feuchtigkeitströpfen durch die Fliehkraft an die Wandung bewegt wer­ den, um dann nach unten zu fließen. Bei diesem Vorgang wird die Strömungsgeschwindigkeit aufgrund des Kondensatabscheider/-ableitervolumens reduziert.The compressed air heated by the compression enters the DL inlet connection, is pre-cooled by the cold compressed air (item 3 ) and then enters the heat exchanger (item 5 ), which is integrated in the condensate separator / drain (item 2 ) is a. This precooled compressed air then enters the compressed air cooler (item 1 ). Here the dew point of the compressed air is undershot, which leads to condensate excretion, whereby the air cooler has an inclination to the compressed air outlet state of 10%, so that the condensate that flows flows into the condensate separator / drain. After the compressed air cooler, the compressed air enters the condensate separator / diverter (item 2 ), where the compressed air flow is rotated by means of a baffle plate and the moisture droplets are moved against the wall by centrifugal force, and then down to flow. In this process, the flow rate is reduced due to the condensate separator / drain volume.

Die Druckluft wird dann durch die eintretende warme Druckluft im Überhitzer (Pos. 3) ca. 20 K über den Taupunkt angehoben und gelangt dann über den Druckluftaustrittsstutzen zum Verbraucher.The compressed air is then raised by the warm compressed air entering the superheater (item 3 ) approx. 20 K above the dew point and then reaches the consumer via the compressed air outlet connection.
