Abstract
Description
Aufgabe der Erfindung ist die Erzeugung eines streufähi gen organisch-mineralischen Düngers aus phosphathaltiger Schmelzvergaser-, Hochofen- und Stahlwerksschlacke unter Zugabe von Gips (Halbhydrat) und ist damit eine Erweite rung von P 37 01 571.0, in welchem die Erzeugung eines dem Thomasmehl ähnlichen Düngers aus mit Phosphaten ange reichterten Schmelzvergaser-, Hochofen und/oder Stahlwerks schlacke beschrieben wird.The object of the invention is to generate a scatterable organic-mineral fertilizer from phosphate-containing Melting gasifier, blast furnace and steel works slag under Adding gypsum (hemihydrate) and is therefore an extension tion of P 37 01 571.0, in which the generation of a fertilizer similar to Thomas flour made from phosphates enriched melting gasifier, blast furnace and / or steel works slag is described.
Klärschlämme und Gülle wurden früher in der Landwirtschaft als natürlicher Dünger eingesetzt. Dies hat sich stark verändert, da gesetzliche Regelungen die Verwertung von Klärschlämmen erschweren und andererseits eine explosions artige Vermehrung der Gülle durch Massentierhaltung, diese nicht mehr ganzjährig einsetzbar macht, da eine Vergiftung des Grundwassers mit Nitraten gegeben ist, was durch ihre Menge verursacht wird.Sewage sludge and manure used to be used in agriculture used as a natural fertilizer. This has been strong changed because legal regulations the recycling of Sewage sludges complicate and on the other hand an explosion like increase of manure through factory farming, this can no longer be used all year round because of poisoning of the groundwater with nitrates, which is due to their Amount is caused.
Aufgabe der Erfindung ist es Klärschlämme (Fäkalien), Gülle, diverse phosphathaltige Schlacken mit Gips (Halbhydrat) zu einem streufähigen organisch-mineralischen Dünger zu ver arbeiten. The object of the invention is sewage sludge (faeces), manure, various phosphate-containing slags with gypsum (hemihydrate) too a sprinkled organic-mineral fertilizer work.
Gelöst wird diese Aufgabe durch mischen von Klärschläm men (Fäkalien) ggf. mit Gülle und Einbringen der Mischung in einen Mischer oder eine Mühle vorzugsweise einer ver tikalen Planetenmühle unter Zugabe von mehlfein gemahlener Schmelzvergaser-, Hochofen- und Stahlwerksschlacke, welche mit aufgeschlossenen Phosphaten angereichert sein sollte, und Gips (Halbhydrat), homogenisieren des Gemenges und Er hitzen durch Eigenerwärmung oder Mantelbeheizung der Mühle auf ca. 65-70°C, und austragen des pastenförmigen Gutes aus der Mühle und Formgebung sowie Trocknung.This task is solved by mixing sewage sludge men (faeces), if necessary with manure and introducing the mixture in a mixer or a mill preferably one ver tical planetary mill with the addition of finely ground flour Melting gasifier, blast furnace and steel works slag, which should be enriched with digested phosphates, and gypsum (hemihydrate), homogenize the batch and Er heat by self-heating or jacket heating of the mill to approx. 65-70 ° C, and discharge the pasty material from the mill and shaping as well as drying.
Die Herstellung eines streu- und lagerfähigen Voll- oder Mehrnährstoffdüngers sowie spezieller Einzeldünger aus den o. g. Materialien, welche ja Abfälle sind, ist ein hervorragendes Beispiel von Recycling, denn durch das Zu sammenverarbeiten der verschiedenen Stoffe wird in den meisten Fällen die Entsorgungsfrage gelöst, ein hochwer tiges Produkt erzeugt und wertvolle Nährstoffe und Spuren elemente, die man auch als Hochleistungselemente bezeichnet und die in Klärschlämmen und Gülle enthalten sind, in den Naturkreislauf zurückgeführt.The production of a scatterable and storable full or Compound fertilizer as well as special single fertilizer the above Materials, which are waste, is a excellent example of recycling, because by closing The various substances are processed together in the in most cases the disposal question was solved, a high quality product and creates valuable nutrients and traces elements that are also called high-performance elements and contained in sewage sludge and manure, in the Natural cycle traced.
Die Feinmahlung der hauptsächlich kalk- und phosphathalti gen Schlacken, was ja meist in Kugel- oder Rohrmühlen er folgt, ist eine Vorgabe um die Homogenisierung in der ver tikalen Planetenmühle zu erleichtern und andererseits den Verschleiß zu begrenzen. Gips dient als hydraulisches Binde mittel, andererseits bindet er NH3 und trägt zur besseren Verteilung im Boden bei, während Holz- oder Strohkohlen staub zur Auflockerung des Bodens bzw. zur Humusbildung beiträgt. The fine grinding of the mainly lime and phosphate-containing slags, which he usually does in ball or tube mills, is a requirement to facilitate homogenization in the vertical planetary mill and, on the other hand, to limit wear. Gypsum serves as a hydraulic binding agent, on the other hand it binds NH 3 and contributes to better distribution in the soil, while charcoal or straw charcoal contributes to loosening the soil or to the formation of humus.
Durch die Eigen- oder Fremderwärmung auf 65-70°C in der Planetenmühle wird eine Hygienisierung herbeige führt.By self or external heating to 65-70 ° C Hygiene is brought about in the planetary mill leads.
Düngemitel können nicht in Staubform angeboten werden, da die Verteilung durch Maschinen bei Nässe ein Verkleben derselben möglich macht. Da aber Granulieren ein gesonder ter Arbeitsgang wäre, wird Trocknung sowie die Erzeugung der gleichmäßigen Stückform in einem Arbeitsgang in der an sich bekannten Rillenwalzen-Trocknung vorgenommen. Vorteile dieses Verfahrens: Abkürzung der Trockenzeit, keine Staub entwicklung, sowie automatische Arbeitsweise. Das Produkt ist anschließend versandfertig.Fertilizers cannot be offered in dust form, since the distribution by machines is a sticking when wet makes it possible. But because granulation is a special one The next step would be drying and production the uniform piece shape in one operation in the known grooved roller drying made. advantages this procedure: shortening the drying time, no dust development, as well as automatic operation. The product is then ready for dispatch.
Fehlende Nährstoffe im Gemenge werden durch Zugabe vor der Planetenmühle ausgeglichen.Missing nutrients in the batch are added by adding before Planetary mill balanced.
