Description

Vorrichtung zur Herstellung von Flammruß Man hat in Flammrußöfen zur Regelung der Luftzufuhr schon schmale Schlitze oder Ringöffnungen angewendet, deren unterer Rand von der senkrechten, die Oberfläche des Verbrennungsgutes etwas überragenden Wanddes Behälters für das Verbrennungsgut gebildet wurde, um die Flammenführung und damit die Rußbildung gleichmäßiger zu gestalten und Mengen und Güte des anfallenden Flammrußes zu erhöhen.Device for the production of lampblack One has in lampblack furnaces for Regulation of the air supply already used narrow slots or ring openings, their lower edge of the vertical, slightly protruding from the surface of the material to be burned Wall of the container for the combustion material was formed around the flame guide and thus to shape the soot formation more evenly and the quantities and quality of the resulting Increase flame black.

Es wurde nun gefunden, daß sich diese Wirkung wesentlich steigern läßt, wenn man den Weg der Verbrennungsluft beeinflußt, indem man die der Luftzuführung zugewandte Wand des Rohstoffbehälters als senkrechte Fläche ausbildet, deren obere Kante die Oberfläche des Verbrennungsgutes wesentlich überragt und diese den Luftweg höher legende Fläche in dem die Oberfläche des Verbrennungsgutes überragenden Teil mit den Durchtritt von Verbrennungsluft gestattenden Öffnungen, wie Schlitzen, Löchern, Düsen o. dgl., versieht.It has now been found that this effect increases significantly if the path of the combustion air is influenced by that of the air supply facing wall of the raw material container forms as a vertical surface, the upper Edge protrudes significantly beyond the surface of the material to be burned and this overhangs the airway higher area in the part protruding from the surface of the material to be burned with openings allowing the passage of combustion air, such as slots, holes, Nozzles or the like, provides.

Bei Verwendung :einer derartigen Fläche, aber ohne Öffnungen, wird durch die Barüberstreichende Luft hinter der Fläche ein Wirbel erzeugt, der den unteren Teil der Flamme gegen diese Fläche saugt und leicht zu Explosionen führt. Diese werden vermieden durch die erfindungsgemäßen Öffnungen, durch die die Flamme hinter dieser Fläche einen Teil Verbrennungsluft erhält. Es wird so durch eine kurze, gleichmäßige Flamme eine beschleunigte und gleichmäßige Rußbildung erreicht unter Erhöhung der auf das angewandte Rotmaterial bezogenen Ausbeute und der Durchschnittsmenge.When using: such a surface, but without openings, will the air passing over the bar creates a vortex behind the surface, which creates the lower part of the flame sucks against this surface and easily leads to explosions. These are avoided by the openings according to the invention through which the flame a part of the combustion air is received behind this area. It becomes so through a short, even flame an accelerated and even soot formation achieved under Increase in the yield related to the red material used and the average amount.

Ohne Verwendung einer das Verbrennungsgut wesentlich überragenden Fläche wurden in einem Flammrußofen aus i ooo kg Anthracenrückständen einmal 295 kg und einmal 3o5 kg Ruß erhalten, im Durchschnitt also 30 %, bezogen auf das Rohmaterial.Without the use of an area significantly larger than the combustion material, 295 kg and 305 kg of soot were obtained in a lampblack furnace from 10,000 kg of anthracene residues, an average of 30% based on the raw material.

Nach Einschaltung einer Fläche mit erfindungsgemäßen Öffnungen wurden aus i ooo kg des gleichen Rohmaterials einmal 49o kg und einmal 54o kg Ruß erhalten, im Durchschnitt also 5i,5 %, bezogen auf das Rohmaterial.After switching on a surface with openings according to the invention were from 10,000 kg of the same raw material one gets 49o kg and one time 54o kg soot, on average therefore 5i.5%, based on the raw material.
