Description

Verfahren zur Beschleunigung der Vakuumfiltration heißer Flüssigkeiten Gegenstand der Erfindung ist lein Verfahren zur Beschleunigung der Vakaumfihration heißer Flüssigkeiten. Gemäß der Erfindung werden die auf der Fjltratseite aus der Flüssigkeit sich entwickelnden. das Vakuum störenden Dämpfe von Zeit zu Zeit durch Rückführung des Filtrats beseitigt. Die Rückführung hat gleichzeitig eine Rückspülung des Filters zur Folge.Process for accelerating the vacuum filtration of hot liquids The invention relates to a method for accelerating the vacuum flow hot liquids. According to the invention, those on the advice page from the Fluid developing. the vacuum interfering vapors through from time to time Recirculation of the filtrate eliminated. The recirculation also has a backwash of the filter.

Es ist wichtig, die das Vakuum störenden Dämpfe von Zeit zu Zeit zu beseitigen, da der Wirkungsgrad der Anlage durch sie erheblich herabgesetzt wird. Die Dämpfe bünden nicht nur der Luftpumpe eine große Belastung auf, sondern nehmen auch einen lerheblichen Teil des eigentlich für das Filtrat bestimmten Raumes ein. Diese Nachteile werden gemäß der Erfindung durch zeitweilige Rückführung und Rückspülung, Maßnahmen, die in der Filtertechnik bereits bekannt sind, beseitigt. It is important to remove the vapors interfering with the vacuum from time to time to be eliminated, as the efficiency of the system is significantly reduced by them. The vapors not only put a lot of stress on the air pump, they also take it away also a significant part of the space actually intended for the filtrate. These disadvantages are alleviated according to the invention by temporary recirculation and backwashing, Measures that are already known in filter technology have been eliminated.

Auf der Zeichnung ist ein Ausführungsbeispiel einer zur Durchführung-des Verfahrens dienenden Anlage dargestellt. The drawing shows an embodiment of one for carrying out the Process-serving plant shown.

Das Filter 10 ist in die warme Rohflüssigkeit II eines Behälters 12 eingetaucht, der durch die Leitung 13 versorgt wird. Vom Filter 10 führt eine Saugleitung 14 zunächst zu einem Dreiweghahn 15 und dann zu einem Saugbehälter I9, der durch eine Leitung 20 mit einer nicht dargestellten Luftpump:e verhunden ist. Das Filtrat wird von einer Naßsaugpumpe 22 durch Leitung 21 aus dem Behärter 19 abgesogen und durch die Druclrleitung 23 gefördert. The filter 10 is in the warm raw liquid II of a container 12 immersed, which is supplied by line 13. From the filter 10 leads a Suction line 14 first to a three-way valve 15 and then to a suction container I9, which is connected through a line 20 to an air pump (not shown). The filtrate is removed from the container 19 by a wet suction pump 22 through line 21 sucked off and conveyed through the pressure line 23.

Der Dreiweghahn 15 steht durch eine Leitung 18 mit einem Rückspülbehälter 26 in Verbindung, der durch ein Schwimmerventil 25 von einer an die Förderleitung 2I angeschlossenden Abzweigung 24 aus gefüllt wird. The three-way valve 15 is through a line 18 with a backwash container 26 in connection, which is connected to the delivery line by a float valve 25 2I connected junction 24 is filled from.

In der gezeichneten Stellung verbindet der Dreiweghahn 15 das Filter mit dem Saugbehälter I9, So daß die Rohflüssigkeit durch das Filter gesaugt wird. Nachdem der Saugte hälter einige Zeit gearbeitet hat, wird der Dreiweghahn 15 auf kurze Zeit in der Pfeilrichtung umgestellt, so daß er die Leitung I8 mit dem Filter 10 in Verbindung bringt und das Filter von dem Saugbehäher absperrt. In the position shown, the three-way valve 15 connects the filter with the suction container I9, so that the raw liquid is sucked through the filter. After the suction container has worked for some time, the three-way valve 15 is open briefly switched in the direction of the arrow, so that it is the line I8 with the filter 10 brings in connection and shuts off the filter from the suction cup.

Hierdurch wird das Filtrat teilweise in das Filter zurückgeführt, schlägt die im Filter befindlichen Dämpfe nieder und spült das Filter durch Rückströmung.This means that some of the filtrate is returned to the filter, precipitates the vapors in the filter and flushes the filter through backflow.
