Description
Wärmeaustauscher, insbesondere für Fernheizwerke zum Betrieb von Zentralheizungsanlagen, mit einem von den Heizmitteln um- und durchflossenen, in einem Gehäuse zwischen Rohrböden angeordneten Rohrbündel Für Fernheizwerke, die zum Betrieb von Zentralheizungsanlagen dienen, werden neuerdings Wärmeaustauscher mit sehr großen Leistungen und entsprechend großen Durchmessern für verhältnismäßig hohe Drücke benötigt.Heat exchangers, especially for district heating plants for the operation of central heating systems, with one of which the heating means flows around and through, in a housing between Tube sheets arranged tube bundle For district heating plants that are used to operate central heating systems are used recently, heat exchangers with very high performance and accordingly large diameters required for relatively high pressures.
Diese Wärmeaustauscher bestehen gewöhnlich aus einem Gehäuse mit einem Rohrbündel, dessen Rohre in einen oder mehrere Rohrböden eingewalzt sind.These heat exchangers usually consist of a housing with a Tube bundle whose tubes are rolled into one or more tube sheets.
Da diese Rohrböden durch die zahlreichen Bohrungen für die Rohre sehr geschwächt werden, ist es schwierig, sie ausreichend widerstandsfähig zu machen, besonders dann, wenn es sich um große Durchmesser und hohe Betriebsdrücke handelt.Since these tube sheets through the numerous holes for the tubes very are weakened, it is difficult to make them sufficiently resilient, especially when it comes to large diameters and high operating pressures.
Es ist nun bekannt, daß man, besonders bei Kondensatoren, den Rohrboden entweder mit dem Anschlußdeckel oder mit einer innerhalb des Anschlußdeckels angeordneten Hilfskonstruktion durch Ankerschrauben- verbindet, oder daß man bei Speisewasservorwärmern den Rohrboden auf der Außenseite mit Rippen versieht.It is now known that, especially in the case of condensers, the tube sheet either with the connection cover or with one arranged within the connection cover Auxiliary structure is connected by anchor bolts, or that one is used in the case of feed water preheaters ribs the tube sheet on the outside.
Bei denWärmeaustauschern für die genannte Verwendung muß gefordert werden, daß die Walzstellen der Rohre auf Dichtigkeit geprüft und nachgewalzt werden können, ohne das Heißwasser aus den Wärmeaustauschern und den Heizanlagen ablassen zu müssen.The heat exchangers for the use mentioned must be required that the rolling points of the pipes are checked for leaks and rolled can without draining the hot water from the heat exchangers and heating systems to have to.
Das Prüfen und Nachwalzen de: Rohre muß also erfolgen können, während der Rohrboden unter dem vollen, oft recht erheblichen Druck des Heißwassers steht.The testing and re-rolling de: pipes must therefore be able to take place while the tube sheet is under the full, often considerable pressure of the hot water.
Dies ist bei beiden bekannten Vorrichtungen, wenn überhaupt, so nur mit großen Schwierigkeiten möglich.This is only the case with both known devices, if at all possible with great difficulty.
Gemäß der Erfindung wird der Rohrboden auf der Innenseite durch angeschweißte oder angegossene Rippen in beliebige Felder unterteilt.According to the invention, the tube sheet is welded on the inside or cast-on ribs divided into any fields.
Die Vorderseite des Rohrbodens ist bei der angegebenen Anordnung vollkommen glatt, so daß die Walzstellen der Rohre unbehindert geprüft und auch nachgewalzt werden können, ohne daß das Heißwasser aus dem Apparat und der Anlage abgelassen werden muß. Bei besonders hohen Drücken und großen Durchmessern kann die Festigkeit des Rohrbodens gemäß der Erfindung noch dadurch erhöht werden, daß er mit einem gegen das Gehäuse passenden zylindrischen Ansatz versehen wird, auf den die Beanspruchung des Rohrbodens durch die Rippen übertragen wird.The front of the tube sheet is perfect in the specified arrangement smooth, so that the rolling points of the pipes can be checked and re-rolled unhindered without draining the hot water from the machine and the system must become. At particularly high pressures and large diameters, the strength of the tube sheet according to the invention can be increased by having a against the housing matching cylindrical approach is provided on which the stress of the tube sheet is transmitted through the ribs.
In der Abbildung ist ein solcher Wärmeaustauscher mit einem Rohrbündel aus U-förmig gebogenen Rohren und einem gemäß der Erfindung ausgebildeten Rohrboden mit zylindrischem Ansatz beispielsweise dargestellt.The picture shows such a heat exchanger with a tube bundle of U-shaped bent tubes and a tube sheet designed according to the invention For example, shown with a cylindrical approach.
In der Abbildung ist a das Gehäuse des Wärmeaustauschers, das von dem in der Anlage umlaufenden Heißwasser durchflossen wird. b ist der Anschlußdeckel, der durch einen Steg in zwei Kammern für die Zuführung des Heizdampfes und Abführung des Kondensates geteilt wird. c ist der Rohrboden mit den aufgeschweißten oder angegossenen Rippen d, dem zylindrischen Ansatz e und dem Flansch f, mittels dessen er an dem Gehäuse a angeschraubt wird.In the figure, a is the housing of the heat exchanger that is used by the hot water circulating in the system flows through it. b is the connection cover, the through a web in two chambers for the supply of the heating steam and discharge of the condensate is divided. c is the tube sheet with the welded or cast on Ribs d, the cylindrical projection e and the flange f, by means of which it is attached to the Housing a is screwed on.
In den Rohrboden c sind die U-förmig gebogenen Rohre g-g eingewalzt, durch die die Wärme vom Heizmittel an das beheizte Mittel übertragen wird.The U-shaped bent tubes g-g are rolled into the tube sheet c, through which the heat is transferred from the heating medium to the heated medium.
