Description

Verfahren zum gleichmäßigen Verteilen von Benetzungsmitteln Be: der Brikettierttn', voll Steinkohlen mit Pech macht sich der hohe Pechzusatz bei der V erltren- nttng der Briketts durch st:irkere I#,ttßl>ildttttg tor- angenehm bemerkbar. Ganz abgesehen von dein wirtschaftlichen Standlnmkt hat man daher ver- sucht, den I'cchzusatz auf verschiedene An zu ver- ringern. Unter anderem wurden bereits 7usätze von C51, Naphthalin usw. vorgeschlagen, die alter isn ungünstigsten Falle nur fein zerstäubt auf das Pech bzw. Brikettiergut aufgespritzt werdest. Diese Verfahren haben alle den großen Nachteil, daß bei den geringen Mengen Ü1 ttsw. von etwa o, i bis o,5°1, bezogen auf das Brikmtiergut. eine gleich- mäßige Verteilung niemals erreicht werden kann und dtwr die anfallenden Briketts sehr verschieden in ihrer (>ruck- und Abriebfestigkeit sind. L-tn eine gute Verteilung der geringen Ölmengen zu erWeit, wird nachstehendes Verfahren ange- wandt. Den für die F_rwärtnung des Brikettiergutes im l,Zttetwcrk notwendigen Dampf wird 01, Naphthalin usw. zugesetzt. In Dampfforsn umgewandelt ge- langt dieses 01, Naphthalin usw. an das kalte Bri- kettiergut, und durch Kondensation benetzt es dann ganz gleichmäßig die gesamte Oberfläche der Kohle und des Peches. Dabei wird auch der I:rweichungs- und Schmelzpunkt des Peches erniedrigt. was eine giinstigew Verteilung des Peches bei niedriger Knettemperatur-ermöglicht sowie eine bessere Verbindungsnaht mit der ölbenetzten und dadurch gelatinierten Oberfläche schafft. Man erzielt damit gleichzeitig eine höhere Festigkeit der Briketts, bzw. bei gleichbleibender Druckfestigkeit kann der Pechgehalt gesenkt werden. Sollen die Öle usw. itn Brikettiergut noch teilweise in harzartige Bindemittel übergeführt werden, so kann man außerdem noch Formaldehyd sowie Katalysatoren, Dämpfe aus Säuren, Ammoniak usw. dem Dampf zusätzlich hinzufügen und damit eine weitere Verbesserung der Brikettierung erreichen.Method of evenly distributing wetting agents Be: the briquette, full of coal with pitch does the high level of pitch add to the nttng the briquettes by st: irkere I #, ttßl> ildttttg tor- pleasantly noticeable. Not to mention yours economic standpoint has therefore seeks to try the addendum in different ways wrestle. Among other things, there were already 7usätze suggested by C51, naphthalene, etc., the older is in the worst case only finely atomized on the Pitch or briquettes are sprayed on. These Processes all have the major disadvantage that with the small quantities Ü1 ttsw. from about o, i to 0.5 ° 1, based on the Brikmtiergut. an equal moderate distribution can never be achieved and dtwr the resulting briquettes very different in their (> resistance to jolting and abrasion. L-tn a good distribution of the small amounts of oil to expand, the following procedure is used. turns. The for the forwarding of the briquette in the l, Zttetwcrk necessary steam becomes 01, naphthalene etc. added. Converted into steam does this 01, naphthalene, etc. reach the cold bri- warps, and then wets it through condensation evenly the entire surface of the coal and bad luck. The I: softening and the melting point of the pitch is lowered. what a Favorable distribution of the pitch at lower Kneading temperature enables and creates a better connection seam with the oil-wetted and thereby gelatinized surface. At the same time, the briquettes are made more rigid, or the pitch content can be reduced with the same compressive strength. If the oils etc. are to be partially converted into resinous binders in the briquetting material, formaldehyde and catalysts, vapors from acids, ammonia etc. can also be added to the steam and thus a further improvement in briquetting can be achieved.

_\uch für andere Vorgänge kann die Verwendung von Dämpfen und deren Kondensation auf deren Gut zum Erreichen technischer Vorteile verwendet werden. So z. B. zum gleichmäßigen Auslaugen, Benetzen, Reinigen usw. von Produkten mittels Wasserdampfes, kondensierbarer Gase und anderer Dämpfe, wobei sich die Waschmengen auf ein Minimum beschränken lassen.The use of vapors and their Condensation on their property can be used to achieve technical advantages. So z. B. for uniform leaching, wetting, cleaning, etc. of products by means of Water vapor, condensable gases and other vapors, whereby the wash quantities keep it to a minimum.
