Description
Verfahren zur Herstellung von Gasruß Gegenstand der Erfindung ist ein Verfahren zur Herstellung von Gasruß.Process for the production of carbon black is the subject of the invention a process for the production of carbon black.
Es wurde schon vorgeschlagen, zuni Zweck dieser Fabrikation natürliche oder industrielle Gase mit \7aphthalindämpfen anzureichern, bevor sie zur unvollständigen Verbrennung @gebracht werden. Diese Verfahren scheinen wegen der veränderlichen Beschaffenheit des erzeugten Gasrußes im gewerblichen Betrieb keinen Eingang gefunden zu haben.It has already been suggested that for the purpose of this manufacture be natural or industrial gases to be enriched with \ 7aphthalene vapors before they become incomplete Incineration @ be brought. These procedures seem changeable because of the The nature of the carbon black produced in commercial operations has not been used to have.
Es wurde gefunden, daß die Qualität des Gasrußes wesentlich von der Anreicherung des Gases mit Nalihtlialindämpfen abhängt und daß infolgedessen die Erreichung einer gleichmäßigen Beschaffenheit, welche dem jeweiligen Verwendungszweck entspricht, durch die vollständig gleichmäßige Anreicherung der Gase unter Ausschluß irgendeines Mitreißen: -,-en Naphthalin in kleinen lllasen gedingt ist. Die zur Erreichung dieses Erfolges nach der Erfindung angewendeten Mittel sind die folgenden, wobei bemerkt wird, daß ihre gleichzeitige Anwendung zwar wünschenswert, aber nicht notwendig ist: In dem Verdampfungsapparat soll die Verdampfungsoberfläche zu dem Ausbreitungsraum im Verhältnis von mindestens i : io stehen, nämlich mindestens i dm2 der Oberfläche des Bades zu io bis 12.dm3 des Volumens des Gases in dessen Ausbreitungsraum. Die Gesch,vindigkeit des Gasstroms soll vorzugsweise innerhalb von o,3 bis, o,5 mIsec, aber jedenfalls weniger als 2 m/sec betragen und wird vorteilhafterweise durch irgendein bekanntes Mittel zur Regelung des Auslasses aufrechterhalten.It has been found that the quality of the carbon black is substantially different from that of Enrichment of the gas with Nalihtlialindampf depends and that, as a result, the Achievement of a uniform quality, which is suitable for the respective purpose corresponds, by the completely uniform enrichment of the gases under exclusion any entrainment: -, - en naphthalene is condensed in small lllases. The for To achieve this success according to the invention applied means are the following, noting that their simultaneous use, while desirable, is not is necessary: In the evaporation apparatus, the evaporation surface should be Dispersion space in the ratio of at least i: io, namely at least i dm2 of the surface of the bath to io to 12.dm3 of the volume of the gas in it Expansion space. The speed of the gas flow should preferably be within from 0.3 to 0.5 mIsec, but in any case less than 2 m / sec and is advantageously maintained by any known means of regulating the outlet.
Der Ausbreitunigsraum soll nicht höher sein als der zwanzigste Teil der Gesamtlänge der Durchlaufsleitung. Bei diesen Bedingungen zeigt es sich, daß die Anreicherung eines bestimmten Gases an \Tapltthalindämpfel und infoLgedessen die Qualität des Gasrußes von der Temperatur der Flüssigkeit und (lern Grad der Vorheizung der Gase abhängt. Beide Bedingungen lassen sich leicht durch wohlbekannte Regelvorrichtungen im Betrieb> einhalten.The expansion space should not be higher than the twentieth part the total length of the flow line. In these conditions shows it turns out that the enrichment of a certain gas in \ Tapltthalindämpfel and The quality of the carbon black depends on the temperature of the liquid and (learn Degree of preheating of the gases depends. Easily pass both conditions Observe well-known control devices during operation.
Obwohl die Erfindung in ihrer Anwendung auf Anreicherung an \'aplithaliin beschrieben ist, kann sie auch in allen Fällen benutzt werden, wo man irgendwelche in Betracht kommenden lease mit Stoffen beladen,will, z. B. mit Rückständen, welche sich unter ähnlichen Bedingungen wie Naphthalin verdampfen lassen.Although the invention in its application to enrichment in \ 'aplithaliin described, it can also be used in all cases where there is any eligible lease loaded with substances, wants, z. B. with residues, which vaporize under conditions similar to naphthalene.
