Regenerierbares Filter. Patentiert im Deutschen Reiche vom 23. März 1915 ab.Regenerative filter. Patented in the German Empire on March 23, 1915.
Die Erfindung betrifft ein durch Hitze regenerierbares Filter, und zwar kommt bei der Herstellung des Filters ein Material zur Verwendung, welches bis zu den höchsten Hitzegraden, bis etwa 2000 ° C, vollständig unverändert bleibt. Dieses Material ist Siliciumcarbid (Carborundum), welches außerdem die Eigenschaft hat, nur mit Wasser oder sonst einem flüchtigen Bindemittel verformt, sich durch kleine, freie Spuren von Kieselsäure zu einem porösen Körper festzubrennen. Das so erhaltene Produkt kann beliebig viele Male bei höchsten Temperaturen ausgeglüht werden, ohne daß die Porosität sich ändert.The invention relates to a heat regenerable filter Manufacture of the filter a material for use, which can be used up to the highest degrees of heat, up to about 2000 ° C, remains completely unchanged. This material is silicon carbide (Carborundum), which also has the property, only with water or otherwise a volatile binder, deformed by small, free traces of silica to burn into a porous body. The product obtained in this way can be used as many times as desired can be annealed at the highest temperatures without changing the porosity.
Ein weiterer Vorteil liegt darin, daß Carborundum (Siliciumcarbid) von keiner Säure angegriffen wird und deshalb auch für die stärksten Säuren als Filter zu verwenden ist. Auch für heiße Gase kann das Filter mit Erfolg Verwendung finden oder direkt bei entsprechender Erwärmung als Filter und Vergaser zugleich gebraucht werden. Es kommt hierbei die bekannte außerordentliche Wärmeleitfähigkeit des Siliciumcarbids mit in Frage.Another advantage is that carborundum (silicon carbide) is free from acid is attacked and is therefore to be used as a filter even for the strongest acids. The filter can also be used successfully for hot gases or directly with the corresponding one Heating as a filter and carburetor are needed at the same time. This is where the well-known extraordinary thermal conductivity comes into play of silicon carbide also in question.
Infolgedessen erwärmt sich der beheizte Filterkörper aus Siliciumcarbid außerordentlich schnell, und gleichmäßig, und ein einem solchen Filterkörper zugeführter zu vergasender Brennstoff, beispielsweise Rohöl, wird unter Abscheidung seiner Verunreinigungen durch das Filter im Innern des heißen Filters gleichmäßig vergast und das Gasgemisch beim Weiterstreichen durch die Filterporen homogenisiert und überhitzt. Die Rückstände in dem Filter werden dann nach Ausschaltung des FiI-ters bei hoher Temperatur herausgebrannt oder mit einem geeigneten Stoff ausgewaschen, wodurch das Filter wieder gebrauchsfähig wird.As a result, the heated filter body heats up made of silicon carbide extremely quickly, and evenly, and one such Fuel to be gasified, for example crude oil, supplied to the filter body is under Separation of its impurities by the filter inside the hot filter evenly gasified and the gas mixture is homogenized as it passes through the filter pores and overheated. The residues in the filter are then removed after the filter has been switched off burned out at high temperature or washed out with a suitable fabric, making the filter usable again.
