KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Das Verfahren besteht in der Verwendung mit Magnesia präparirter Kohle und hinsichtlich der speciellen Ausführung darin, dafs der Wasserreinigungsapparat nach Patent No. 16574 von Bohlig und Heyne mit der Abweichung zur Verwendung kommt, dafs das Füllmaterial, Holzraspelspäne mit Magnesia Mg(OH)2 präparirt, zuvor einem Glühprocefs unter, völligem Luftabschlufs unterworfen wird.The method consists in the use of charcoal prepared with magnesia and, as regards the special design, in that the water purification apparatus according to patent no. 16574 by Bohlig and Heyne is used with the difference that the filling material, wood shavings prepared with magnesia Mg (OH) 2 , is first subjected to an annealing process with complete air exclusion.
Das neue Füllmaterial besteht also aus frisch geglühter Holzkohle, auf welcher das Magnesiahydrat in gleicher Weise wie vorher auf der Holzfaser fest aufgelagert ist, so dafs auch hier ein mechanisches Abspülen mit Wasser nicht stattfindet. Die geglühte Masse wird, mit der nöthigen Menge Wasser vermischt, auf Haufen gebracht, wo nach kurzer Zeit unter beträchtlicher Erhitzung die Hydratbildung vor sich geht.The new filling material consists of freshly annealed charcoal, on which the magnesia hydrate is firmly supported on the wood fiber in the same way as before, so that too mechanical rinsing with water does not take place here. The annealed mass is, with the necessary amount of water mixed, brought into heaps, where after a short time under considerable heating the hydrate formation takes place.
Mit . dieser lockeren Masse werden die drei Cylinder der erwähnten Reinigungsbatterie dicht angefüllt, und ist die Rohrverbindung der drei neben einander placirten Cylinder so geordnet, dafs die Filtration darin stets von unten nach oben und in dem bekannten regelmäfsigen Turnus automatisch vor sich geht.With . The three cylinders of the aforementioned cleaning battery are sealed against this loose mass filled, and the pipe connection of the three cylinders placed next to one another is so arranged that that the filtration is always from bottom to top and in the familiar regular manner Cycle takes place automatically.
Die Batterie wirkt continuirlich. Die betreffende Flüssigkeit, insbesondere der saturirte, bei der Zuckerfabrikation heifse Zuckersaft, wird durch Pumpen vom Kalkschlamm in ein höher stehendes Bassin abgehoben, von wo er unter ca. 3 m Druckhöhe durch die Batterie geführt wird. Wenn die Cylinder der Reihenfolge nach mit I, II, III bezeichnet sind, so tritt im ersten Turnus die Flüssigkeit bezw. der Saft im Cylinder I ein, von da nach II, um bei III gereinigt und geklärt auszufliefsen.The battery works continuously. The fluid in question, especially the saturated one, In sugar production, hot sugar juice is pumped into a lime sludge higher standing basin lifted, from where it is under approx. 3 m pressure height through the battery to be led. If the cylinders are designated in the order I, II, III, then occurs in the first cycle the liquid respectively. the juice in cylinder I, from there to II, um at III to flow out purified and clarified.
Ist nach einiger Zeit der Inhalt im Cylinder I erschöpft, so wird er entleert und frisch gefüllt. Es beginnt nunmehr der zweite Turnus, in welchem durch geeignete Hahnumstellung die Flüssigkeit bezw. der Saft in Cylinder II eintritt und nach Passiren von Cylinder III in Cylinder I zum Ausfliefsen gelangt. Im dritten Turnus wird Cylinder II frisch gefüllt und durch Hahnstellung der Durchflufs von Cylinder III, I, II im vierten Turnus wieder wie zu Beginn der Durchflufs von I zu II und III bewirkt etc.If after some time the content in cylinder I is exhausted, it is emptied and freshly filled. The second cycle now begins, in which the Liquid resp. the juice enters cylinder II and after passing through cylinder III in Cylinder I reaches the outflow. In the third cycle, Cylinder II is freshly filled and by stopping the flow of cylinders III, I, II in the fourth cycle again like at the beginning of the flow from I to II and III, etc.
Die chemische Einwirkung der Magnesia Mg(O H)2 besteht zunächst in der Absorption der vorhandenen halbgebundenen oder freien Kohlensäure, wodurch der Kalk sein Lösungsmittel verliert und in Form von Kalkspat so fest auf die Kohle krystallirt, dafs er, wie es bei der Magnesia der Fall ist, mechanisch nicht mehr davon zu trennen ist. Die Durchlässigkeit der Cylinder ist deshalb eine immer gleiche und Verstopfung nicht möglich. Von. der Magnesia geht ein Theil in Lösung als kohlensaure Magnesia und sichert insbesondere beim Zucker eine stete alkalische Reaction, ohne wie der Aetzkalk durch- Einwirkung auf schwefelsaures Kali schädliches Aetzkali bilden zu können.The chemical action of magnesia Mg (OH) 2 consists first of all in the absorption of the semi-bonded or free carbonic acid present, whereby the lime loses its solvent and crystallizes so firmly on the coal in the form of calcite that it crystallizes on the coal, as is the case with magnesia is, can no longer be separated from it mechanically. The permeability of the cylinder is therefore always the same and blockage is not possible. From. A part of the magnesia goes into solution as carbonic magnesia and, especially with sugar, ensures a constant alkaline reaction, without being able to form harmful caustic potash, like caustic lime, by the action of sulphate of potash.
Neben dieser Wirkung der Magnesia entzieht die frisch geglühte Holzkohle jedweder Flüssigkeit, insbesondere dem Zuckersaft, zugleich denIn addition to this effect of the magnesia, the freshly glowed charcoal removes any liquid, especially the sugar juice, at the same time the
Farbstoff, so dafs 'die Knochenkohle entbehrlich wird.Dye, so that charcoal can be dispensed with will.
