Abstract
Description
Die vorliegende Erfindung betrifft ein Verfahren zur Aufbereitung von Reststoffen aus der Biogaserzeugung und ihre Verwendung in der Landwirtschaft sowie in der Gärtnerei.The The present invention relates to a process for the preparation of Residues from biogas production and their use in agriculture as well as in the nursery.
Biogas wird derzeit hauptsächlich aus Mais hergestellt. Dabei wird Mais zerkleinert eingesetzt und anaerob von Mikroorganismen umgesetzt, wobei Methan entsteht. Der Kohlenstoffgehalt des Materials sinkt, während insbesondere der Stickstoffgehalt gleich bleibt bzw. durch die Masseabnahme prozentual steigt. Wenn die Methanproduktion abnimmt, wird der Vorgang zu einem bestimmten Zeitpunkt abgebrochen. Der Rückstand enthält dann die an Kohlenstoff abgereicherten Pflanzenreste, die in nahezu flüssiger Konsistenz mit einem Trockensubstanzgehalt von nur ca. 15% vorliegen.biogas is currently mainly made from corn. This corn is used shredded and anaerobically reacted by microorganisms, producing methane. Of the Carbon content of the material decreases, while in particular the nitrogen content is the same remains or by the decrease in weight increases in percentage. If the methane production decreases, the process is aborted at a certain time. The residue contains then the carbon-depleted plant remains, which are almost liquid with a dry matter content of only about 15%.
Bislang wurde dieser Rückstand als Dünger in der Landwirtschaft verwertet.So far became this backlog as fertilizer in utilized in agriculture.
Es ist nun Aufgabe der vorliegenden Erfindung, ein Verfahren zur Aufbereitung dieser Rückstände zu schaffen und neue Verwendungen hierfür anzugeben.It Now is an object of the present invention, a method for processing to create this residue and to indicate new uses for it.
Weil der Rückstand zunächst getrocknet und dann gebrochen oder gemahlen und gegebenenfalls pellettiert wird, kann er wesentlich einfacher gehandhabt werden. Auch die Verpackung und der Transport über längere Strecken wird wirtschaftlicher.Because the residue first dried and then crushed or ground and optionally pelleted can be handled much easier. Also the packaging and the transport over longer Stretching becomes more economical.
Bei der neuen Verwendung als Zuschlagsstoff zu Torf mit einem Anteil von 5% bis 50% ergibt sich ein nährstoffhaltiges Produkt, das zudem verbesserte Eigenschaften als Strukturmaterial in der Gärtnerei und in der Landwirtschaft aufweist.at the new use as aggregate to peat with a share from 5% to 50% results in a nutrient-containing Product that also has improved properties as a structural material in the nursery and in agriculture.
Die Verwendung als Düngematerial ist ebenfalls möglich und dort vorteilhaft, wo keine Kunstdünger oder auf Tierfäkalien basierenden Dünger einsetzbar sind.The Use as fertilizer is also possible and there advantageous, where no artificial fertilizers or based on animal feces fertilizer can be used.
Durch dieses Substrat gibt sich ein leichteres Wurzeln der Pflanzen. Da die Erde homogener ist, hat diese eine bessere Wasserführung und eine schwarz-graue Farbe.By This substrate gives easier plant roots. There the earth is more homogeneous, this has a better water supply and a black and gray color.
Transportkosten beim Torf werden reduziert, da mehr Paletten geladen werden können (leichtere Tüten bei gleicher Füllmenge). Es findet auch eine Entlastung der landwirtschaftlichen Flächen statt, da der Dünger in anderen Bereichen neue Verwendung findet.transport costs peat is reduced because more pallets can be loaded (lighter bags at same capacity). There is also a relief of agricultural land, because of the fertilizer finds new uses in other areas.
Nachfolgend wird ein Ausführungsbeispiel der Erfindung beschrieben.following is an embodiment of Invention described.
Ausgangsstoff ist der Rückstand aus der Biogaserzeugung auf Basis von Mais oder Gülle mit einem Gehalt von 3–12% Trockensubstanz (TS). Dieses Material wird zunächst in einem Separator vorgetrocknet auf einen Trockensubstanzgehalt von 25% TS. Danach läuft die Masse über einen Bandtrockner und wird auf 94% bis 96% TS getrocknet. Das trockene Endprodukt wird gebrochen, gemahlen oder pellettiert. Die Konsistenz entspricht vorzugsweise etwa getrockneter Maissilage.starting material is the residue from biogas production based on maize or manure with a content of 3-12% Dry matter (TS). This material is first predried in a separator to a dry matter content of 25% TS. After that runs the Mass over a belt dryer and is dried to 94% to 96% TS. The dry one End product is crushed, ground or pelleted. The consistency preferably corresponds to about dried corn silage.
Das
Produkt wird durch die folgenden physikalischen Eigenschaften charakterisiert:
Dichte
1 Liter = 100 g
Korngröße 0–10 mmThe product is characterized by the following physical properties:
Density 1 liter = 100 g
Grain size 0-10 mm
Das Produkt ist schüttfähig, fließfähig, und pumpfähig.The Product is pourable, free-flowing, and pumpable.
Das
Produkt hat in diesem Ausführungsbeispiel
folgende chemische Eigenschaften:
Gesamtstickstoff (N) 1,19%
Ammoniumstickstoff
(NH4) 0,24%
Phosphor (P2O5)
0,74%
Kalium (K2O) 0,47%

Der Rest nach Bioabfallverordnung.The product has the following chemical properties in this embodiment:
Total nitrogen (N) 1.19%
Ammonium nitrogen (NH4) 0.24%
Phosphorus (P 2 O 5 ) 0.74%
Potassium (K 2 O) 0.47%
Magnesium (MgO) 0.26%
Calcium (CaO) 0.71%
Sulfur (S) 0.11%
Copper (Cu) 9.80 mg / kg
The rest according to the Biological Waste Ordinance.
Dieses Produkt wird nachfolgend Granulat genannt.This Product is called granules below.
Eine bevorzugte Verwendung ist die Beimischung von Granulat zu frisch gestochenem Torf in einem Verhältnis von 100 g (1 Liter) Granulat zu 500–700 g (1 Liter) Torf. Durch diese Zumischung erhöht sich der Nährstoffgehalt des Torf und die Dichte nimmt ab. Das Produkt ist deshalb in der Anwendung vorteilhaft und beim Transport auf LKW wirtschaftlicher, denn durch die hohe Dichte des reinen Torfs ist das Gewicht einer Standard-Transportpalette so hoch, dass das mögliche Ladevolumen eine LKW nicht ausgenutzt wird. Bei der Mischung von Torf und Granulat sinkt die Dichte so weit, dass beispielsweise in einen Sattelzug 32 Paletten Mischung statt nur 24 Paletten reinen Torfs geladen werden können.A preferred use is the addition of granules to fresh pricked peat in a ratio from 100 g (1 liter) granules to 500-700 g (1 liter) peat. By this admixture increased the nutrient content of the peat and the density decreases. The product is therefore in the Application advantageous and more economical to transport on trucks, Because of the high density of pure peat, the weight of a Standard transport pallet so high that the possible loading volume is not a truck is exploited. The mixture of peat and granules sinks Density so far that, for example, in a semitrailer 32 pallets Mixture instead of just 24 pallets of pure peat can be loaded.
Eine weitere Verwendung ergibt sich im Obst- und Gemüseanbau und insbesondere im Weinbau, wo das Granulat unmittelbar als Bodenstrukturverbesserer mit Düngereigenschaften eingesetzt werden kann.A further use results in the fruit and vegetable cultivation and in particular in the Viticulture, where the granules immediately as Bodenstrukturverbesserer with fertilizer properties can be used.
Schließlich kann das Granulat auch als Heizmaterial eingesetzt werden, beispielsweise bei der Beheizung von Biogasanlagen.Finally, can the granules are also used as heating material, for example in the heating of biogas plants.
Vorteilhafte
