Description
Verfahren zur Kontrolle der Auslaugung in Diffusionsbatterien Dichtemessungen beim Auslaugen sind in der Zuckerfabrikation bisher nur bei der Dichtemessung des Rohsaftes durchgeführt worden. Die Dichtemessung des Rohsaftes andererseits läßt nicht den Auslaugezustand erkennen, sondern weist höchstens bei anormalen Rohsaftdichten auf einen anormalen Zustand hin. Für ,eine stetige Überwachung der Auslaugung ist die Dichtemessung des Rohsaftes nicht geeignet.Procedure for the control of leaching in diffusion batteries density measurements during leaching in sugar production so far only in the density measurement of the Raw juice has been carried out. The density measurement of the raw juice, on the other hand, leaves does not recognize the state of leaching, but at most shows abnormal raw juice densities indicates an abnormal condition. For, there is constant monitoring of leaching the density measurement of the raw juice is not suitable.
Die Erfindung geht von der Feststellung aus, daß eine urgenügende Auslaugung der Schnitzel stets einen zu hohen Zuckergehalt im Ablaufwasser zeitigt. Das Verhältnis des Zuckergehalts in den ausgelaugten Schnitzeln zum Zuckergehalt im Ablaufwasser ist praktisch konstant.The invention is based on the finding that a very sufficient Leaching of the schnitzel always results in too high a sugar content in the drainage water. The ratio of the sugar content in the leached schnitzel to the sugar content in the drainage water is practically constant.
Gemäß der Erfindung wird demgemäß der Zuckergehalt des Ablaufwassers der Diffixsionsbatterie zugrunde gelegt, um die Auslaugung zu kontrollieren, und zwar in der Form, daß dieser Gehalt mittels registrierender Dichtemesser stetig überwacht wird. Die stetige Überwachung ermöglicht es, Dichteschwankungen sofort bei Entstehen festzustellen und sofort die erforderliche Abhilfe zu schaffen.According to the invention, the sugar content of the drainage water becomes accordingly based on the diffusion battery to control leaching, and in the form that this content is constant by means of recording densitometers is monitored. The constant monitoring enables density fluctuations to be detected immediately to determine when they arise and to take the necessary remedial action immediately.
Die Auslaugekontrolle wurde bisher lediglich durch periodische Untersuchungen der entleerten, ausgelaugten Schnitzel und des Ablaufwassers durchgeführt, d. h. in Zeitabständen von r bis i1/2 Stunden. Man stellte also nur den Auslaugezustand im Augenblick der Probeentnahme fest. Was sich in der Zwischenzeit bezüglich des Auslaugezustandes wirklich abspielte, darüber hatte man keinerlei Kenntnis. Da andererseits der Diffusionsprozeß stetig verläuft, können in der Zeit zwischen den bisher geübten Probeentnahmen Auslaugeveränderungen eintreten, die, weil sie nicht erkannt wurden, gerade durchaus erhebliche und unerwünschte Zuckerverluste nach sich zagen.Leaching control has so far only been carried out through periodic examinations the emptied, leached chips and the drainage water carried out, d. H. at intervals of r to i1 / 2 hours. So you only set the leaching state at the moment of taking the sample. What has happened in the meantime with regard to the The state of leaching actually took place, no one had any knowledge about it. There on the other hand the diffusion process runs steadily, can in the time between the previously practiced Sampling changes in leaching occur which, because she does not were recognized, just after quite considerable and undesirable sugar losses to hesitate.
Das Ergebnis einer laufenden Messung im Sinne der Erfindung ist überraschend. Es ergeben sich daraus Dichte- und sonach Auslaugeschwankungen erheblicher Größe, die man bisher überhaupt nicht festgestellt und zum Ausgangspunkt weiterer Überlegungen gemacht hat.The result of an ongoing measurement within the meaning of the invention is surprising. This results in fluctuations in density and therefore leaching of considerable magnitude, which has not yet been established at all and is the starting point for further considerations has made.
Aus der Anzeige der Dichteschwankunged des Ablaufwassers lassen sich Bedienungsfehler, z. B. solche in der Ventilstellung, sofort erkennen. Die Messung erfolgt durch Dichtewaagen, durch welche Ablaufwasserproben von jedem zur Entleerung gelangenden Diffuseur gepumpt werden. Die Dichte-«-aagen registrieren die Dichteermittlung fortlaufend im Sinne der Erfindung.From the display of the density fluctuation of the drainage water Operating errors, e.g. B. immediately recognize those in the valve position. The measurement is carried out by density scales, through which drain water samples from each for emptying reaching diffuser can be pumped. The density - «- aagen register the density determination ongoing within the meaning of the invention.
