Description

Bei Wärmeaustauschern ergeben sich, wenn diese mit niedrigen Dampfdrücken gefahren werden, insbesondere bei Mehrstufentauchverdampfern in der zweiten und dritten Stufe Schwierigkeiten, die Rohrschlangen in solcher Anzahl unterzubringen, daß die Dampfgeschwindigkeit in den Rohreintrittsquerschnitten in .zulässigen Grenzen bleibt.In the case of heat exchangers, if these have low vapor pressures be driven, especially with multi-stage submersible evaporators in the second and third stage difficulty in accommodating the number of coils that the steam speed in the pipe inlet cross-sections within .permissible limits remain.

Bei Wärmenustauschern, deren Heizsystem aus einem Bündel gerader, mit Rohrplatten verbundener Heizrohre besteht, ist es bekannt, eine Unterteilung in zwei Rohrbündel vorzunehmen, wobei die Kondensatorgruppe aus weniger Rohren besteht als die obere Heizrohrgruppe. Bei Wärmeaustauschern, deren Heizsystem aus Rohrschlangen besteht, könnte man zwar ebenfalls zusätzlich zu einem Heizdampf- ein Kondensat-Röhrschlangensystem anordnen und beide durch eine Zwischenkammer miteinander verbinden, dies würde jedoch zu einer verwickelten schweren und sperrigen Bauweise führen.For heat exchangers whose heating system consists of a bundle of straight, consists of heating pipes connected to tube plates, it is known to have a subdivision to be carried out in two tube bundles, whereby the condenser group consists of fewer tubes than the upper heating tube group. In the case of heat exchangers, their heating system consists of pipe coils exists, one could also use a condensate pipe coil system in addition to a heating steam arrange and connect both through an intermediate chamber, but this would result in an intricate, heavy and bulky construction.

Andererseits haben Wärmeaustauscher mit Rohrschlangen gegenüber den Wärmeaüstauschern mit Rohrbündeln und Rohrplatten mancherlei Vorzüge; so ist z. B. das Heizsystem für Reinigungszwecke besser zugänglich und es läßt sich auf einfachere Weise eine Anpassung an die jeweiligen Wärmeübertragungsverhältnisse erzielen.On the other hand, heat exchangers with tube coils have opposite the Heat exchangers with tube bundles and tube plates have various advantages; so is z. B. the heating system for cleaning purposes more accessible and it can be easier Way to achieve an adaptation to the respective heat transfer conditions.

Erfindungsgemäß lassen sich bei Wärmeaustauschern mit Heizrohrschlangen bei raum= und materialsparender Bauweise große Eintrittsquerschnitte für den Dampf und kleine Austrittsquerschnitte für das Kondensat erzielen und damit unerwünschte Druckverluste beim Übergang in die Rohre vermeiden, indem die Heizrohrschlangen in ihrem Anfangsteil aus mehreren Strängen bestehen, die zu einem gemeinsamen Kondensatrohrstrang zusammengeführt sind.According to the invention, heat exchangers with heating coils can be used with space- and material-saving design, large inlet cross-sections for the steam and achieve small outlet cross-sections for the condensate and thus undesirable Avoid pressure losses at the transition into the pipes by removing the heating coils consist in their initial part of several strands that form a common condensate pipeline are merged.

Zweckmäßig werden die Rohrschlangen vertikal angeordnet, so daß ihre Stränge an eine gemeinsame Dampfkammer angeschlossen werden können. Dadurch wird ferner ermöglicht, neben der Anzahl auch die Länge der Heizrohrschlangenstränge _den wärmetechnischen Verhältnissen anzupassen.Appropriately, the pipe coils are arranged vertically so that their Strands can be connected to a common steam chamber. This will also enables the length of the heating coiled strands in addition to the number _ to adapt to the thermal conditions.

Die Erfindung sei beispielsweise veranschaulicht. Abb. i und 2 zeigen eine Rohrschlange für Tauchverdampfer nach der Erfindung in zwei verschiedenen Ausführungsformen.The invention is illustrated by way of example. Fig. I and 2 show a coil for submersible evaporator according to the invention in two different embodiments.

Bei der in Abb. i dargestellten Rohrschlange sind"zwei Stränge 1, 2 vorgesehen, die an getrennte Dampfeintrittskammern 3, 4 angeschlossen und zu einem gemeinsamen Kondensatrohrstrang 5 zusammengeführt sind. Die Rohrschlänge ist waagerecht angeordnet und die Kondensatabzweigung in der Mitte angeschlossen.In the pipe coil shown in Fig. I, "two strands 1, 2 provided, which are connected to separate steam inlet chambers 3, 4 and become one common condensate pipeline 5 are merged. The pipe loop is horizontal arranged and the condensate branch connected in the middle.

Eine bessere Kondensatableitung und für die Anpassung an die gegebenen wärmetechnischen Verhältnisse günstigere Anordnung zeigt Abb. 2. Die den Anfangsteil der Rohre bildenden Stränge 6, 7 sind an eine gemeinsame Dampfeintrittskammer 8 angeschlossen. Dabei kann die Rohrschlange vertikal angeordnet und die Abzweigung 9 der. Kondensatrohrschlange io auf beliebiger Höhe der Rohrschlange angeordnet werden..Better condensate drainage and for adapting to the given Fig. 2 shows the arrangement which is more favorable in terms of thermal engineering the strands 6, 7 forming the tubes are connected to a common steam inlet chamber 8 connected. The pipe coil and the branch can be arranged vertically 9 the. Condensate pipe coil io arranged at any height of the pipe coil will..
