Description

Kreisender Tronümelentwickler zum Vergasen von Carbid unter Gewinnung trockenen Kalkhydrats Die bekannten Verfahren zum Vergasen von Carbid unter gleichzeitiger Bildung trockenen Kalkhydrates sind noch sehr ut1-vollkommen. Die Vergasung wurde seither z. B. durch Zuführen von Wasser in einer mit Schlitzen oder siebartigen Öffnungen versehenen kreisenden Trommel vorgenommen. Wenn diese Öffnungen eng waren, so traten regelmäßig Verstopfungen oder Verklebungen auf, die durch allerlei Hilfsmittel beseitigt werden sollten. Wurden die Schlitze jedoch weit gemacht, so war es nötig, eine zweite Vergasungseinrichtung anzuordnen, um die durchgefallenen kleinen Körner ebenfalls zu vergasen.Orbiting drum developer for the gasification of carbide with extraction dry hydrated lime The well-known method for gasifying carbide with simultaneous The formation of dry hydrated lime is still very perfect. The gassing was since then z. B. by supplying water in a slot or sieve-like Orifices provided rotating drum made. If these openings were narrow clogging or sticking occurred regularly, caused by all kinds of aids should be eliminated. However, if the slits were made wide, it was necessary to arrange a second gasifier to remove the fallen small grains also to be gassed.

Durch die an sich ebenfalls bekannte Verwendung von wasserdampfgesättigtem Acetylen war es möglich, die Nachteile teilweise zu vermeiden, weil man dabei auf die unmittelbare Wasserzuführung verzichten konnte. Es genügt jedoch nicht, durch die Carbidstücke das wasserdampfgesättigte Acetylen hindurchzublasen, weil auch hierbei ein Zusammenbacken der angegasten Carbidstücke eintrat. Auch das Bewegen der aufeinanderliegenden Carbidstücke in einer Trommel während des Durchleitens von wasserdampfgesättigtem Acetylen brachte keine vollständige Vergasung.Due to the use of water vapor saturated, which is also known per se Acetylene made it possible to avoid the disadvantages partly because one was doing so could do without the direct water supply. However, it is not enough to go through the carbide pieces to blow the steam-saturated acetylene through, because too this caused the gassed carbide pieces to stick together. Moving too of the carbide pieces lying on top of one another in a drum while being passed through acetylene saturated with water vapor did not result in complete gasification.

Nach der vorliegenden Erfindung wird das Carbid in einer geschlossenen kreisenden Trommel vergast. Schlitze und Öffnungen, die sich verstopfen oder verkleben können und eine häufige Reinigung notwendig machen, besitzt die Trommel nicht mehr.According to the present invention, the carbide is in a closed gassed rotating drum. Slots and openings that are clogged or stuck together and require frequent cleaning, the drum no longer has it.

Um eine vollständige Vergasung sicher zu erreichen, hat die luftgekühlte und schräg gelagerte dichte Trommel im Innern Mitnehmerschaufeln, die das Carbid hochheben und fallen lassen bzw. umwälzen, wobei das Carbid von dem wässerdampfgesättigten Acetylen vollständig umspült wird. Der durch das Umwälzen der Carbidstücke vollständig trockene Vergasungsrückstand wird fortlaufend durch die Reib- und Scheuerwirkung wieder entfernt, so daß das wasserdampfgesättigte Acetylen stets auf frische Flächen trifft, wodurch die Vergasung beschleunigt wird. Der Rückstand wird mechanisch ausgetragen, indem der trockene Kalk sich infolge seines geringeren spezifischen Gewichtes gegenüber dem Carbid oben auf das Carbid lagert und allmählich an das Trommelende bewegt wird. Damit keine unvergasten Carbidstücke an das Trommelende gelangen können, wird die Trommel kegelstumpfförmig ausgeführt oder bei zylindrischer Ausführung schräg gelagert. Der Neigungswinkel kann so gewählt werden, daß bei entsprechender Länge der Trommel alle Stücke vergast sind, bis sie an das Trommelende gelangen.In order to safely achieve complete gasification, the air-cooled and diagonally mounted, sealed drum inside driving vanes that carry the carbide lift up and drop or stir, removing the carbide from the saturated water vapor Acetylene is completely washed around. Completely by overturning the carbide pieces dry gasification residue is continuously caused by the rubbing and scouring effect removed again, so that the water vapor-saturated acetylene is always on fresh surfaces hits, whereby the gasification is accelerated. The residue is removed mechanically, in that the dry lime opposes each other due to its lower specific weight the carbide is stored on top of the carbide and is gradually moved to the end of the drum. The The drum has a frustoconical design or, in the case of a cylindrical design, is mounted at an angle. The angle of inclination can be chosen so that with a corresponding length of the drum all pieces are gassed until they reach the end of the drum.

Die Trommel wird als druckfester Körper ausgebildet und ist von außen mit Luft gekühlt. Zur Erhöhung der Kühlwirkung können außen Rippen angebracht werden. Die Trommel wird an ihren beiden Enden mit Stopfbüchsen abgedichtet und von außen mittels Zahnrads o. dgl. angetrieben.The drum is designed as a pressure-resistant body and is on the outside cooled with air. Ribs can be attached to the outside to increase the cooling effect. The drum is sealed with stuffing boxes at both ends and from the outside by means of a gear or the like. Driven.

In der Zeichnung ist ein Ausführungsbeispiel eines solchen Trommelentwicklers dargestellt. Aus dem Vorratsbehälter a wird das Carbid von einer Fördervorrichtung b in die Trommel c geleitet, wo das Carbid durch die Mitnehmerschaufeln d ständig umgewälzt wird. Diese Umwälzung hat zur Folge, daß der trockene, pulverige Vergasungsrückstand sich ebenfalls dauernd in Bewegung befindet und als leichterer Bestandteil der Trommelfüllung dem offenen Trommelende zugeführt wird, wo er in den unten angebrachten Auffangbehälter e hineinfällt.In the drawing is an embodiment of such a drum developer shown. The carbide is taken from the storage container a by a conveying device b is fed into the drum c, where the carbide is constantly passed through the driver blades d is circulated. This circulation has the consequence that the dry, powdery gasification residue is also constantly in motion and as a lighter component of the drum filling is fed to the open end of the drum, where it is placed in the collecting container below e falls into it.

Die Trommel c besteht aus einem druckfesten Mantel, auf den außen Kühlrippen angeschweißt sind, und wird mittels eines Getriebes durch den Motor f in Bewegung gesetzt.The drum c consists of a pressure-resistant jacket on the outside Cooling fins are welded on, and is driven by the motor f set in motion.
