KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die bis jetzt bekannten Carbonisationsverfahren beruhen auf dem System der Zuführung und Durchstreichung von Abgasen einer Feuerung, beispielsweise einer Koks-, Anthracit- oder Holzkohlenfeuerung zum Trocknen bezw. zum Verdampfen der Feuchtigkeit in einem luftdicht verschlossenen Ofen, bei deren Entfernung sich gleichzeitig die Carbonisation vollziehen soll. Auch werden die gereinigten Abgase aus Brennöfen, z. B. aus Kalkbrennöfen, zum Trocknen und Carbonisiren benutzt unter Zufuhrung von Wasserdämpfen.The carbonization processes known up to now are based on the feed system and stripping of exhaust gases from a furnace, for example a coke, anthracite or charcoal firing for drying respectively. to evaporate the moisture in one airtightly sealed oven, which, when removed, causes carbonization to take place at the same time target. The cleaned exhaust gases from kilns, e.g. B. from lime kilns, Used for drying and carbonizing with the addition of water vapors.
Beide Verfahren erfüllen ihren Zweck nur unvollständig, da sich im ersteren Falle bei der Zuführung von nur Abgasen die Carbonisirung allein bei Temperaturen unter 300° C. vollzieht, im anderen Falle dieselbe durch die erneute Zufuhr von Wasserdämpfen verzögert und unvollständig wird.Both methods only incompletely fulfill their purpose, since in the former case the supply of exhaust gases only, the carbonization only at temperatures below 300 ° C. in the other case it is delayed by the renewed supply of water vapors and becomes incomplete.
Die vorliegende Erfindung kennzeichnet ein Verfahren, bei dessen Anwendung sich Trocknung und Carbonisation gleichmäfsig und vollständig vollziehen sollen.The present invention features a method which uses drying and carbonization should be uniform and complete.
Es besteht einestheils in der Vermischung der zuzuführenden Abgase mit einem gleichen Quantum atmosphärischer oder kohlensäurehaltiger Luft und in der Zufuhr bezw. dem Durchstreichenlassen dieser Mischung durch die zu carbonisirenden Materialien, anderentheils in der Zufuhr bezw. in dem Durchziehenlassen eines Stromes ^abgekühlter, kalter Kohlensäure durch die mit heifsen Abgasen behandelten ausgetrockneten Materialien.It consists, on the one hand, of mixing the exhaust gases to be fed in with the same Quantum of atmospheric or carbonated air and respectively in the supply. to the Allowing this mixture to pass through the materials to be carbonized, on the other hand in the feed respectively. in the passing of a stream ^ cooled, cold Carbonic acid through the dried-out materials treated with hot exhaust gases.
Die Carbonisirung vollzieht sich erst hierdurch vollständig, bezw. es werden erst dann die Endzwecke einer guten Carbonisation erreicht. The carbonization only takes place completely in this way, respectively. it will only then achieves the end purposes of good carbonization.
Das neue Verfahren besteht demnach in der Mischung der Abgase einer Koks-, Anthracit- oder Holzkohlenfeuerung oder der Mischung der Abgase aus Brennöfen, z. B. Kalkbrennöfen mit atmosphärischer oder kohlensäurehaltiger Luft in dem Verhältnifs, dafs zu gleichen Theilen Abgasen gleiche oder noch gröfsere Theile atmosphärischer oder kohlensäurehaltiger Luft den zu carbonisirenden Materialien in einem luftdicht verschlossenen, langgestreckten Trockenofen zugeführt bezw. dafs das zu behandelnde Carbonisationsgut von solchen Luft- und Abgasemischungen durchstrichen und demselben die ihm innewohnende Feuchtigkeit entzogen wird. Hierbei geht schon eine theilweise Carbonisation vor sich. Nach einer bestimmten Zeit bezw. nachdem sämmtliche Feuchtigkeit verdampft ist, wird die nunmehr heifse, ausgetrocknete Waare in einen Kühlraum gebracht und entweder von einem Strom kalter Kohlensäure aus einer Kohlensäureflasche oder von einem ununterbrochenen Strom abgekühlter Kohlensäureabgase aus der betreffenden Feuerung behandelt. The new process therefore consists of mixing the exhaust gases of a coke, anthracite or charcoal firing or the mixture of exhaust gases from kilns, e.g. B. Lime kilns with atmospheric or carbonated air in such a ratio that in equal parts exhaust gases are the same or even more larger parts of atmospheric or carbonated air are to be carbonized Materials fed respectively in an airtight, elongated drying oven. that the carbonization material to be treated is streaked with such air and exhaust gas mixtures and its inherent moisture is withdrawn from it. Partial carbonization is already taking place here. After a certain time respectively. after all moisture has evaporated, becomes the now hot, dried out goods were brought into a cold room and either from a stream of cold carbon dioxide from a carbon dioxide bottle or from an uninterrupted one Treated stream of cooled carbon dioxide gases from the furnace in question.
Die Ausführung des in den Zeichnungen dargelegten Verfahrens kennzeichnet sich wie folgt:The execution of the procedure outlined in the drawings is marked as follows:
T ist ein Trockenofen, worin das zu behandelnde Trockengut durch die Abgase einer Feuerung oder eines Brennofens unter Mischung derselben mit atmosphärischer oder kohlensäurehaltiger Luft behandelt wird. K ist ein T is a drying oven, in which the dry material to be treated is treated by the exhaust gases of a furnace or a kiln while mixing them with atmospheric or carbonated air. K is a
