Description
Verfahren zur Herstellung von verschweltem Kork Es ist bekannt, in einem Drehrohrofen Kork zu verschwelen, und zwar mittels Gasen, die durch Verbrennung erzeugt werden. Weiterhin wurde festgestellt, daß die Gase, die zum Veredeln des Korkschrotes benutzt werden, so weit sauerstofffrei sein müssen, daß eine Selbstentzündung des Korkes infolge des Sauerstoffes verhindert wird. Wenn die hei,-ßen Korkkörner, die eine Temperatur von 3oo bis q.00° C besitzen, mit Sauerstoff zusammenkommen, so oxydieren sie sieh sofort. Dadurch wird die Oberfläche der Korkkörner angegriffen, so daß ein Materialverlust entsteht. Je mehr Sauerstoff vorhanden ist, desto geringer wird die Ergiebigkeit des Schwelprozesses, und außerdem verringern sich die Güte und Druckfestigkeit des gewonnenen Korkschrotes.Process for the production of carbonized cork It is known in to smolder cork in a rotary kiln by means of gases produced by combustion be generated. It was also found that the gases used to refine the Cork meal is used so that it must be free of oxygen to prevent spontaneous combustion the cork is prevented as a result of the oxygen. When the hot cork grains which have a temperature of 3oo to q.00 ° C, come together with oxygen, so they oxidize immediately. This attacks the surface of the cork grains, so that there is a loss of material. The more oxygen there is, the less becomes the productivity of the smoldering process, and also the quality decrease and compressive strength of the extracted cork pellets.
Die Erfindung besteht darin, mit Gasen zu verschwelen, die größere Mengen Sauerstoff enthalten, ohne daß der Kork selbst angegriffen wird. Zur Durchführung des Verfahrens bläst man sehr feinen, leicht brennbaren Staub, wie beispielsweise Stein- oder Braunkohlenstaub, in das Gas hinein. Der Staub erwärmt sich rasch und oxydiert sich mit dem im Gas vorhandenen Sauerstoff. Der Kork j selbst reagiert mit dem Sauerstoff viel langsamer, so daß die Oberfläche der Korkkörner in keiner Weise angegriffen wird. Um mit einer gewissen Sicherheit den vorhandenen Sauerstoff, soweit erforderlich, zu binden, ist es notwendig, reichliche Mengen Staub einzublasen. Der fein verteilte, organische Staub bindet außerordentlich leicht den Sauerstoffgehalt der Luft, ehe noch eine Reaktion mit den Schwelmaterialien eintreten kann. Es ist nicht notwendig, den Korkstaub vor dem Einblasen anzuwärmen, um eine rasche Reaktion herbeizuführen.The invention consists in smoldering with gases, the larger one Contain lots of oxygen without attacking the cork itself. To carry out the process blows very fine, easily combustible dust, such as Hard coal or lignite dust into the gas. The dust heats up quickly and oxidizes with the oxygen present in the gas. The cork j itself reacts with the oxygen much slower, so that the surface of the cork grains in none Way is attacked. In order to use the available oxygen with a certain degree of certainty, if necessary to bind, it is necessary to blow in copious amounts of dust. The finely divided, organic dust binds the oxygen content extremely easily in the air before a reaction with the smoldering materials can take place. It is it is not necessary to warm the cork dust before blowing it in to ensure a quick reaction bring about.
Besonders gute Resultate erzielt man mit fein verteiltem Korkstaub, der den Sauerstoff der Heizgase gut aufnimmt und den zu verschwelenden Kork stark schützt.Particularly good results are achieved with finely divided cork dust, which absorbs the oxygen from the heating gases well and the cork to be smoldered strong protects.
