KAISERLICHES PATENTAMT.IMPERIAL PATENT OFFICE.
Die vorliegende Erfindung beruht auf dem in der Patentschrift 86913 niedergelegten Gedanken, die in der Melasseentzuckerung und Brennerei als Endproduct auftretende Schlempe dadurch nutzfähiger zu machen, dafs man sie unter Beseitigung des üblen Geruchs der Schlempegase unter Luftabschlufs zur Verkohlung bringt und die hierbei auftretenden flüchtigen stickstoffhaltigen Destillationsproducte soweit erhitzt, dafs dadurch die Bildung von Cyanverbindungen veranlafst wird.The present invention is based on the idea laid down in patent specification 86913, the stillage occurring as an end product in the molasses desugarization and distillery to make them more useful by removing the bad smell of the Brings slurry gases to charring with the exclusion of air and the resulting volatile nitrogenous distillation products are heated to the point where the formation of Cyan compounds is initiated.
Bei dem bisherigen Verfahren wurden die gebildeten Gase. in der Weise cyanisirt, dafs man sie von aufsen erhitzte enge Kanäle passiren liefs (Patentschrift 87725). Dies hatte einestheils den Nachtheil, dafs man, um eine vollständige Ausbeute zu .gewinnen, die Gase einen sehr langen Weg durch die engen Kanäle machen lassen mufste, anderntheils aber bei dem starken Erhitzen der Gase letztere feste, kohlehaltige Niederschläge zurückliefsen, welche nach verhältnifsmäfsig kurzer Zeit die Kanäle derart verengten, dafs sie unbrauchbar wurden und durch die von ihnen gebildeten,, die Wärme schlecht leitenden Isolirschichten der für den gedachten Zweck nothwendigen Regelung der Wärme ein unbequemes Hindernifs in den Weg stellten. Aufserdem traten durch unvermeidliches Undichtwerden der Kanalwandungen Differenzen zwischen den Schlempegasen und den Feuerungsgasen ein, welche Verluste brachten.In the previous process, the gases formed were. cyanized in such a way that they were allowed to pass through narrow channels heated from the outside (patent specification 87725). This had on the one hand the disadvantage that, in order to obtain a complete yield, the gases are combined had to make a very long way through the narrow canals, but on the other hand with the strong heating of the gases caused the latter solid, carbonaceous precipitates to flow back after a comparatively short time the canals became so narrowed that they became unusable and through the insulating layers formed by them, which are poorly conductive to heat, for the The intended purpose of the necessary regulation of the heat creates an uncomfortable obstacle in the way posed. In addition, the sewer walls inevitably leaked Differences between the pulp gases and the combustion gases include what losses brought.
Die vorliegende Erfindung hilft diesen Mifsständen ab. Sie gestattet nicht nur die Verwendung compacterer Apparate, sondern auch eine wesentliche Ersparnifs an Brennmaterial und aufserdem eine kräftigere Einwirkung der Hitze auf die zu cyanisirenden Gase.The present invention remedies these misgivings. It doesn't just allow use more compact apparatus, but also a substantial saving in fuel and also a more powerful action of the Heat on the gases to be cyanized.
Bei Ausführung des Verfahrens wird das in anderen Fabriken bereits mit Vortheil verwendete Regenerativsystem zur Anwendung gebracht. When the process is carried out, it is already being used to advantage in other factories Regenerative system brought into use.
Zu diesem Zwecke werden -Retorten verwendet, welche mit Contactstücken aus feuerbeständigem Material (Chamotte und dergl.), etwa ähnlich wie in der Patentschrift 15751 beschrieben, ausgefüllt sind. Diese Contact-, körper werden auf irgend eine der bekannten Weisen durch directes Feuer auf die nothwendige Reactionstemperatur erhitzt. Ist diese erreicht, so wird die Feuerung abgestellt, und es beginnt nunmehr das Durchleiten der Schlempegase. Diese erhitzen sich durch die directe Hitze der Contactkörper sehr rasch, cyanisiren sich und treten oben wieder aus. Während der Cyanisirung setzen die Gase feste kohlenstoffhaltige Producte an den Contactkörpern ab, derart, dafs diese schliefslich ganz damit überzogen sind.For this purpose retorts are used, which are made with contact pieces made of fire-resistant Material (chamotte and the like), somewhat similar to that in patent specification 15751 described, are filled out. These contact bodies are based on one of the known ones They are heated to the necessary reaction temperature by direct fire. Is this reached, the furnace is turned off, and it now begins to pass through the Whipping gases. These heat up very quickly due to the direct heat of the contact bodies, cyanise and exit again at the top. During the cyanization the gases solidify carbon-containing products from the contact bodies, in such a way that these finally become completely are covered with it.
Ist der ~ Betrieb so weit gediehen, so wird der Gaszuflufs zu den Oefen abgestellt und in einen mittlerweile vorerhitzten zweiten Apparat geleitet. Auf diese Weise findet der wirthschaftlich so vortheilhafte continuirliche Betrieb statt.If the ~ business has progressed so far, so will the gas supply to the ovens is shut off and into a second apparatus that has meanwhile been preheated directed. In this way the economically so advantageous continuous operation finds itself instead of.
Der erschöpfte Apparat wird von Neuem geheizt und hierbei der Heizwerth des früher als grofser .Mifsstand angesehenen kohlenstoff-The exhausted apparatus is heated again, and the calorific value of the previous one carbon-
haltigen Niederschlages in der Weise ausgenutzt, dafs er verbrennt und dadurch die Erhitzung gerade an den wichtigsten Stellen, nämlich an den Contactstellen befördert, was nicht allein einen raschen Betrieb, sondern eine · Ersparnifs an Brennmaterial ergiebt.rich precipitate is exploited in such a way that it burns and thereby the Heating at the most important points, namely at the contact points, promotes what not only a quick operation, but a saving of fuel.
Schlempegase eignen sich für das vorliegende Verfahren am besten, doch ist nicht ausgeschlossen, dafs das gleiche Verfahren sich auch bei anderen cyanisirungsfähigen Gasen verwenden läfst.Slurry gases are best suited for the present process, but it is not excluded that that the same procedure can also be used with other gases capable of cyanization running.
