Description
Verfahren. zum Betrieb einer mehrstufigen Verdampfanlage Die Erfindung bezieht sich auf den Betrieb von mehrstufigen Verdampfanlagen, denen die einzudampfende Flüssigkeit, z. B. Zuckerdünnsaft, in wechselnder Menge und Dichte zuströmt.Procedure. for operating a multi-stage evaporation plant. The invention refers to the operation of multi-stage evaporation systems, which are to be evaporated Liquid, e.g. B. thin sugar juice, flows in varying amounts and density.
Narb der Erfindung soll eine derartige Anlage so betrieben werden, daß, die Dampfzufuhr zu den einzelnen Verdampfkörpern in Abhängigkeit von der Dichte des eingedampften Stoffes selbsttätig geregelt wird. Hierdurch wird erreicht, daß die Dichte des eingedampften Produkts, z. B. des Zuckerdicksaftes, stets gleichbleibt.According to the invention, such a system is to be operated that, the steam supply to the individual evaporators depending on the density of the evaporated substance is regulated automatically. This achieves that the density of the evaporated product, e.g. B. the sugar syrup, always remains the same.
Die Erzielung konstanter Dichte wird also hier bewirkt durch selbsttätige Regelung des Verdampfungsmittels, des Heizdampfes, im Gegensatz zu bekannten Methoden, bei welchen konstante Dichte des Produkts dadurch erreicht werden soll, daß das Produkt jeweils selbsttätig aus dem Verdampfungsapparat abgelassen wird, sobald es auf eine bestimmte Dichte .eingedickt ist.The achievement of constant density is thus brought about here by automatic Control of the evaporation agent, the heating steam, in contrast to known methods, at which constant density of the product is to be achieved that the Product is automatically drained from the evaporator as soon as it is thickened to a certain density.
In der Zeichnung ist ein Ausführungsbeispiel .einer mehrstufigen Verdampfanlage gezeigt, die gemäß der Erfindung betrieben werden soll.The drawing shows an exemplary embodiment of a multi-stage evaporation system shown to be operated according to the invention.
Die Verdampfanlage besteht hier beispielsweise aus den Verdampfkörpern t, a -und, 3, die untereinander durch die Brüdendampfleitungen q. und 5 verbunden sind, so daß die Brüder aus dem Verdampfkörper r den Verdampfkörper z heizen und die Brüder aus dem Verdampfkörper z den Verdampfkörper 3. In die Brüderleitung 5 ist nun z. B. ein Ventil oder eine Drosselklappe 6 eingebaut, die durch einen in die Leitung 7 für das eingedampfte Erzeugnis, also z. B. den Zuckerdicksaft, eingebauten Dichterregler 8 beeinflußt wird.The evaporation system here consists, for example, of the evaporation bodies t, a -and, 3, which are interconnected by the exhaust steam lines q. and 5 connected are, so that the brothers from the evaporator r heat the evaporator z and the brothers from the evaporator body z the evaporator body 3. In the brothers line 5 is now z. B. a valve or a throttle valve 6 installed, which by an in the line 7 for the evaporated product, so z. B. the sugar syrup, built-in Density regulator 8 is influenced.
Der Dichterregler bewirkt, daß sich das Ventil 6 bei fallender Dichte des Dicksaftes öffnet und bei steigender Dichte schließt. Der Verdampfkörper 3 wird also bei fällender Dichte des Erzeugnisses in erhöhtem Maße Dampf erhalten, bei steigender Dichte in geringerem Maße, bzw. .er wird im ersten Falle zugeschaltet, im zweiten Falle abgeschaltet.The density regulator causes the valve 6 to move when the density falls of the syrup opens and closes with increasing density. The evaporator 3 is So if the density of the product is falling, there is an increased amount of steam increasing density to a lesser extent, or it is switched on in the first case, switched off in the second case.
Die gleiche-. Einrichtung kann selbstverständlich auch an mehreren Verdampfkörpern angeordnet werden, z. B. am Körper - oder an z und a oder auch an einem etwa vorhandenen vierten Körper, der als Nachverdampfer wirkt. Es ist dabei gleichgültig, ob der betreffende Verdampfer noch mit überdruck oder bereits im Vakuum arbeitet, wenn sich auch im allgemeinen die häufigste Anwendung bei zusammengesetzten Verdampfanlagen ergeben wird.The same-. Establishment can of course also be carried out on several Evaporators are arranged, for. B. on the body - or at z and a or also at a fourth body, if present, which acts as a re-evaporator. It is there It does not matter whether the evaporator in question is still with overpressure or already in a vacuum works, albeit in general the most common application in compound Evaporation systems will result.
