Description

Bei Eindampf- und Trockenanlagen, welche durch überhitztes Wasser beheizt werden, erscheint es in der Technik oft nötig, die betreffenden Apparate nach Beendigung eines -Eindampf- oder Trockenprozesses zur Vermeidung von unwirtschaftlichen Zeitverlusten möglichst schnell zu kühlen, um die fertige Charge entleeren zu können. Es läßt sich dies auf verschiedene Weise durch Luft- oder Wasserkühlung des mit dem überhitzten Wasser gefüllten Heizrohrsystems ermöglichen. Dabei hat es sich jedoch als unzweckmäßig erwiesen, einen intensiv wirkenden Kühler, in das Heizrohrsystem selbst, einzu-In the case of evaporation and drying systems which are heated by overheated water, appears it is often necessary in technology to avoid the apparatus concerned after the end of an evaporation or drying process to cool the finished product as quickly as possible from wasted time To be able to empty the batch. It can be done in different ways by air or Allow water cooling of the heating pipe system filled with the overheated water. However, it has proven to be inexpedient to incorporate an intensely effective cooler into the heating pipe system itself.

X5 bauen, weil durch die wiederholte schnelle Abkühlung und Wiedererhitzung des Rohrsystems das physikalische Gefüge des Kühlrohrmaterials sehr bald so stark verändert wird, daß es den bei dem eigentlichen Heizprozeß auftretenden hohen Drucken von einigen hundert Atmosphären nicht mehr widerstehen kann. X 5 build because the repeated rapid cooling and reheating of the pipe system very quickly changes the physical structure of the cooling pipe material to such an extent that it can no longer withstand the high pressures of a few hundred atmospheres that occur during the actual heating process.

Es wurde nun gefunden, daß man diese Übelstände durch Einschaltung einer absperrbaren, gekühlten Nebenleitung, welche zugleich den Vorteil aufweist, während des Kühlprozesses nicht den hohen Betriebsdruck aushalten zu müssen, und welche sich im Notfalle auch leicht ohne Betriebsstörung auswechseln läßt, vermeiden kann. Dadurch wird erst eine dauernde Betriebsfähigkeit der Anlage gewährleistet. Die Zirkulation des überhitzten Wassers durch die Nebenleitung wird mit Hilfe des durch die Kühlung erzeugten Temperaturgefälles ermöglicht und kann durch Einschaltung einer Zirkulationspumpe in das Rohrsystem der Nebenleitung wesentlich beschleunigt werden. Die Zeichnung zeigt eine Ausführungsform des zu beheizenden Apparates α mit den Heizschlangen b und den Verbindungsleitungen c, ferner die abschließbare Nebenleitung d mit Kühler e und Pumpe f. Der Anschluß der Pumpe an die Nebenleitung kann entweder direkt oder durch Zwischenschaltung eines kleinen Behälters g erfolgen. Zum Arbeiten ohne Pumpe dient die in der Zeichnung punktierte Leitung h. It has now been found that these inconveniences can be avoided by switching on a lockable, cooled secondary line, which also has the advantage of not having to withstand the high operating pressure during the cooling process and which can easily be replaced in an emergency without operating disruptions. This is the only way to ensure that the system can be operated over the long term. The circulation of the overheated water through the secondary line is made possible with the help of the temperature gradient generated by the cooling and can be significantly accelerated by switching on a circulation pump in the pipe system of the secondary line. The drawing shows an embodiment of the apparatus to be heated α with the heating coils b and the connecting lines c, and also the lockable secondary line d with cooler e and pump f. The pump can be connected to the secondary line either directly or by interposing a small container g . The dotted line h in the drawing is used to work without a pump.
