Description
Verfahren zur Herstellung von Düngemitteln Es ist bekannt, den bei Gichtgasreinigungsanlagen anfallenden Staub wegen seiner hohen Gehalte an Kali-, Phosphorverbindungen und Kalk als Dügemittel zu verwenden. Dieser Verwendung entgegen stehen seine pyrophoren Eigenschaften, sein niedriges spezifisches Gewicht und seine Feinheit. Durch Anwendung geeigneter Maßnahmen, z. B. Einnebeln des schlammförmigen Staubes zur Trocknung in einem heißen Gasstrom u. ä., versuchte man daher, ihn in eine streufähige, körnige Ware zu verwandeln, der man gegebenenfalls andere bekannte Düngemittel zusetzen könnte.Process for the production of fertilizers It is known that the at Blast furnace gas cleaning systems accumulate dust because of its high content of potash, Use phosphorus compounds and lime as fertilizers. Against this use stand its pyrophoric properties, its low specific weight and its Fineness. By applying suitable measures, e.g. B. Fogging the muddy Dust for drying in a hot gas stream and the like, attempts were therefore made to put it in to transform a spreadable, granular product that is known to others if necessary Could add fertilizers.
Man hat zwar schon den trockenen Gichtstaub, so wie er anfiel, auf die Felder gefahren, doch geschah dies nur von den Landwirten, die in der Nähe der Anfallstelle wohnten. Eine allgemeinere Verwendung hat der Lichtstaub jedenfalls nicht gefunden, auch dann nicht, als man ihn nach einem der bekannten Verfahren in eine streufähige körnige Ware verwandelte, was nicht weiter überraschte, da Versuche des Erfinders ergeben haben, äaß Gichtstaub trotz seiner an sich günstigen Zusammensetzung keine bemerkenswerte Düngewirkung zeigt.You already have the dry gout dust as it was generated drove the fields, but this was only done by the farmers who lived near the Place of occurrence lived. In any case, light dust has a more general use not found, not even after one of the known methods turned into a granular product that could be sprinkled, which was not surprising given attempts of the inventor have shown that gout dust in spite of its favorable composition shows no remarkable fertilizing effect.
Die Erfindung geht von der Erkenntnis aus, daß sich der Gichtstaub
aus Trockengasreinigungsanlagen dann mit überraschend großem Erfolg zu Düngezwecken
verwenden läßt, wenn er anderen Düngemitteln, insbesondere Hüttenkalk oder Ammoniumsulfat,
in geringer Menge zugesetzt wird. Als günstige Menge hat sich ein Zusatz von io
bis 3o°/, ergeben. Als besonders wirkungsvoll erwies sich bei der erfindungsgemäßen
Herstellung von Düngemitteln ein solcher Filterstaub aus der Trockengichtgasreinigung,
bei der vor die Filterschläuche noch Wirbler eingeschaltet waren. Solche Staube
zeigen einen sehr hohen Anteil an Metallen bzw.
Metalloxyden, die
nicht nur für sich auf den Pflanzenwuchs günstig einwirken, sondern auch auf die
bessere Ausnutzung der Düngewirkung der Hauptmasse des Düngemittels einwirken. So
zeigte z. B. ein bei der trockenen Gichtgasreinigung anfallender Filterstaub etwa
folgende Zusammensetzung:
Es ist nicht erforderlich, den Gichtstaub in körnige Form zu bringen, wenn man ihn dem Hüttenkalk vor dem Mahlen zusetzt oder, wenn man ihn mit anderen künstlichen Düngemitteln oder auch Stalldünger innig mischt. Beim Zusatz zu Ammoniumsulfat ergibt sich als weiterer Vorteil, daß etwa noch vorhandene freie Schwefelsäure neutralisiert wird.It is not necessary to bring the gout dust into granular form, when you add it to the slag lime before grinding or when you add it with others artificial fertilizers or manure mixes intimately. When added to ammonium sulfate Another advantage is that any free sulfuric acid still present is neutralized will.
Zu den Trockengasreinigungsanlagen gehören im Sinne der Erfindung auch solche, bei denen der Gichtgasstaub auf elektrischem Wege niedergeschlagen wird.The dry gas cleaning systems belong in the context of the invention also those in which the gas dust is electrically precipitated will.
