Description

Dampfwasser-Rückspeiseanlage. Das in den Dampfleitungen sich niederschlagende Wasser wird in der Regel von den verschiedenen Leitungen Ales Rohrnetzes aus zu einem Sammelpunkt geführt und durch Kondenstöpfe ins Freie geschafft. Sobald aber dieses Kondenswasser mit der äußeren Atmosphäre in Verbindung kommt, saugt es gierig Sauerstoff auf, was vermieden werden muß, wenn das Kondenswasser in den Dampfkessel zurückgespeist werden soll.Steam water recovery system. That which is precipitated in the steam pipes Water is usually supplied from the various lines of Ales' pipe network led to a collection point and made outside through condensate pots. As soon as When this condensation comes into contact with the outside atmosphere, it greedily sucks Oxygen on, which must be avoided if the condensation water in the steam boiler should be fed back.

Dieser Übelstand soll durch vorliegende Erfindung dadurch beseitigt werden, daß das Niederschlagswasser der Dampf leitungen einem unter demselben Drucke stehenden Sammelbehälter zufließt und von hier aus einer unter entsprechend hohem Druck stehenden Stufe einer als Speisepumpe dienenden Kreiselpumpe zufließt und mit dem anderen Speisewasser zusammen in denKesselgedrückt wird. Es sind zwar als Speisepumpen benutzte Kreiselpumpen bereits bekannt, _ bei denen Frischwasser einer höheren Stufe der Kondensatpumpe zugeführt wird. Bei der neuen Anlage wird das unter hohem Druck stehende Kondensat einer solchen Kreiselpumpe an geeigneter Stelle zugeführt.This drawback is intended to be eliminated by the present invention be that the rainwater of the steam lines one under the same pressure standing collecting tank flows in and from here a correspondingly high Pressurized stage of a centrifugal pump serving as a feed pump flows in and is pressed into the boiler together with the other feed water. Although they are as Feed pumps used centrifugal pumps already known, in which fresh water one higher stage of the condensate pump is fed. With the new system this will be under High pressure condensate fed to such a centrifugal pump at a suitable point.

Wie aus der Zeichnung ersichtlich, wird das Kondenswasser aus den verschiedenen Dampfleitungen A in einen gemeinsamen Sammler B geleitet, von welchem es, ohne mit der Atmosphäre in Verbindung zu treten, direkt in den Dampfkessel C rückgespeist wird. Die Rückspeisung erfolgt durch eine mehrstufigeKesselspeise-Kreiselpumpe D, die im übrigen zur Speisung von Wasser verwendet wird, welches eine ganz bedeutend geringere Temperatur als das Kondenswasser hat, welches aus den Dampfleitungen zum Sammler B geführt wird. Das aus dem Sammler B der Kesselspeisepumpe D zufließende Wasser wird nicht in die erste, also die saugende Stufe, sondern in die zweite oder eine dahinterliegende Stufe, die unter keinen Umständen unter Saugspannung steht, geführt, so daß einmal das aus dem Sammler B kommende Kondenswasser nicht mit der Atmosphäre in Berührung treten kann und außerdem nur eine geringe Druckerhöhung braucht. um in den Dampfkessel C rückgespeist zu werden. Das Kondenswasser steht im Sammler B unter dein vollen Dampfdruck der Kesselanlage und hat ungefähr die Temperatur des gesättigten Dampfes, d. h. bei so Atm. etwa 25o° C. Ein derart heißes Wasser könnte durch eine gewöhnliche Kolben- oder Kreiselpumpe nicht gefördert werden, weil eine Abdichtung der Wellen bei hohem Dampfdruck und hoher Temperatur schwierig ist. Indem nun das Kondenswasser in eine der Stufen der Kesselspeisepumpe D _geleitet wird. kommt es mit dem Speisewasser von weit geringerer Temperatur in innigeVerbindung. Die Temperatur des Hauptspeisewassers steigt dadurch nur um ein ganz geringes, so daß die Kesselspeisepumpe durch die Zuleitung des mit hoher Temperatur eintretenden Kondenswassers nicht schädlich beeinflußt wird.As can be seen from the drawing, the condensation water from the various steam lines A is fed into a common collector B , from which it is fed back directly into the steam boiler C without coming into contact with the atmosphere. The feed back takes place through a multi-stage boiler feed centrifugal pump D, which is also used to feed water, which has a significantly lower temperature than the condensation water that is led from the steam lines to the collector B. The water flowing from the collector B of the boiler feed pump D is not fed into the first, i.e. the sucking stage, but into the second or a subsequent stage, which is under no circumstances under suction, so that the condensation water coming from the collector B once cannot come into contact with the atmosphere and, moreover, only needs a slight increase in pressure. to be fed back into the steam boiler C. The condensed water in collector B is under your full steam pressure of the boiler system and has approximately the temperature of the saturated steam, ie at this atm. around 25o ° C. Such hot water could not be conveyed by an ordinary piston or centrifugal pump, because sealing the shafts is difficult at high steam pressure and high temperature. By now channeling the condensation water into one of the stages of the boiler feed pump D _. it comes into intimate contact with the feed water at a much lower temperature. As a result, the temperature of the main feed water only rises by a very small amount, so that the boiler feed pump is not adversely affected by the supply of the condensation water entering at a high temperature.

Die Zuführung des Kondenswassers aus dem Behälter B in die Stufenpumpe D kann sowohl gleichbleibend als auch mit Unterbrechung erfolgen. Für den letztgenannten Fall werden zweckmäßig Schwimmerventile oder auch selbsttätige elektrische Schaltvorrichtungen mit dem Sammler B in Verbindung gebracht, derart, daß der Zulauf des Kondenswassers vom Sammler B zur Stufenpumpe D nur dann freigegeben wird, wenn im Sammler genügend Kondenswasser vorhanden ist.The condensation water can be fed from the container B into the stage pump D either continuously or intermittently. In the latter case, float valves or automatic electrical switching devices are connected to the collector B in such a way that the condensation water inlet from the collector B to the stage pump D is only released when there is sufficient condensation water in the collector.
