Abstract
Description
Die Erfindung betrifft ein Verfahren und eine Vorrich tung zur Aufbereitung tierischer Abfallprodukte durch Abtrennen der flüssigen Komponente.The invention relates to a method and a Vorrich processing of animal waste products Separate the liquid component.
Der mit der Massentierhaltung verbundene starke Anfall tierischer Stoffwechselprodukte führt zu einer Reihe von Problemen insbesondere im Hinblick auf die dadurch hervorgerufene Umweltbelastung. Das wohl gravierendste Problem in diesem Zusammenhang resultiert aus der kon zentrierten Ausbringung dieser Abfallstoffe in Form von Gülle auf landwirtschaftlich genutzte Flächen, da dies eine starke Belastung der Böden und als Folge davon auch das Grundwasser mit Nitrat verursacht.The strong attack associated with factory farming animal metabolites lead to a number of problems especially with regard to this environmental pollution. Probably the most serious Problem in this context results from the con centered application of these waste materials in the form of Manure on agricultural land as this a heavy load on the soil and as a result also caused the groundwater with nitrate.
Bekannte Lösungsansätze, die darin bestehen, diese Ab fallstoffe in Regionen zu transportieren, in denen sie als Düngemittel sinnvoll einzusetzen sind, scheitern unter anderem daran, daß hierfür große Transportkapazi täten erforderlich sind, die ihrerseits einen erheb lichen Kostenaufwand verursachen.Known approaches that consist of this Ab to transport waste materials to regions in which they are sensible to use as fertilizers fail among other things, that large transport capacities for this actions are required, which in turn raise cause costs.
Aufgabe der Erfindung ist es, ein Verfahren und eine Vorrichtung zur Aufbereitung derartiger Abfallstoffe anzugeben, das durch die möglichst vollständige Ab trennung der flüssigen Phase eine wesentliche Redu zierung des Transportaufwandes ermöglicht, das die volle Düngekraft der mit diesem Verfahren erzeugten Produkte gewährleistet und bei dem das im Ausgangs produkt enthaltene Wasser so weit aufbereitet wird, daß es ohne weitere Nachbehandlung zurück in den natür lichen Wasserkreislauf geführt werden kann. Ferner soll durch die Erfindung, die Durchführung möglichst geringem Einsatz von Fremdenergie erfolgen.The object of the invention is a method and Device for processing such waste to indicate that by the most complete Ab separation of the liquid phase a significant reduction adornment of the transport effort enables the full fertilizing power of the generated with this method Guaranteed products and with which in the output water contained in the product is treated so far that it back into the natural without any further treatment Liche water cycle can be performed. Furthermore should through the invention, the implementation as possible low use of external energy.
Die Erfindung löst die Aufgabe durch Verfahrens schritte, die im Kennzeichen des Patentanspruchs 1 an gegeben sind. Eine Vorrichtung, gemäß der Erfindung, wird durch die Merkmale des Patentanspruches 7 gekenn zeichnet. Die weiteren Patentansprüche beinhalten vor teilhafte Weiterbildungen, die im wesentlichen der Optimierung des Verfahrens und der Vorrichtung nach der Erfindung dienen.The invention solves the problem by method steps in the characterizing part of claim 1 given are. A device according to the invention is characterized by the features of claim 7 draws. The further claims contain partial further training, which is essentially the Optimization of the method and the device according to the Serve invention.
Im folgenden soll die Erfindung anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher er läutert werden. Es ist dabei in schematischer Darstellung ein Querschnitt durch eine Anlage zur Aufbereitung von tierischen Dungstoffen gezeigt.In the following the invention is based on one in the Drawing he illustrated embodiment closer to be refined. It is schematic Representation of a cross section through a plant for Treatment of animal manure shown.
Die Anlage besteht zunächst aus einem Behälter 1, in den die anfallende Gülle über einen Zeitraum gelagert, der hinreichend lang ist, um den Prozeß der Bildung von Methangas (CH4) ablaufen zu lassen. Die mittlere Ver weildauer des Ausgangsproduktes in diesem Behälter 1 liegt in der Größenordnung von etwa 30 Tagen. Das entstehende Methangas wird über eine Rohrleitung 2, in die ein Filter 3 eingebaut ist, in einem Speicher 4 geleitet, dessen unterer Teil mit Wasser gefüllt ist. Das Filter 3 dient dem Zweck, etwaig im Methangas ent haltene Anteile an Schwefelwasserstoffgas (H2S) zu ab sorbieren, da dieses Gas aufgrund seiner hohen Aggres sivität zu einem verstärkten Auftreten von Korrosions schäden führen würde.The plant initially consists of a container 1 in which the manure accumulated is stored for a period of time which is sufficiently long to allow the process of methane gas (CH 4 ) formation to take place. The mean Ver dwell time of the starting product in this container 1 is of the order of about 30 days. The resulting methane gas is passed through a pipeline 2 , in which a filter 3 is installed, in a store 4 , the lower part of which is filled with water. The filter 3 serves the purpose of possibly containing in the methane gas contained portions of hydrogen sulfide gas (H 2 S) from, since this gas would lead to increased occurrence of corrosion damage due to its high aggressiveness.
Ein Teil der im Behälter 1 enthaltenen Gülle wird kon tinuierlich über eine Leitung 5 einer Zentrifuge 6 zu geführt, in der der größte Teil der im Ausgangsprodukt enthaltenen Flüssigkomponente abgetrennt wird. Die da durch erhaltene weitgehend verfestigte Substanz wird über eine weitere Leitung 7 in einem Trockner 8 über führt, in dem die noch verbliebene Restfeuchtigkeit entfernt wird und aus dem das trockene, feste Endpro dukt als hochwertiger natürlicher Düngstoff entnommen werden kann, der wegen des Fehlens flüssiger Anteile nunmehr einen wesentlich geringeren Platzbedarf auf weist und der überdies wegen seiner trockenen Konsistenz einfach zu handhaben und zu verpacken ist.Part of the manure contained in the container 1 is continuously fed via a line 5 to a centrifuge 6 , in which the major part of the liquid component contained in the starting product is separated. The largely solidified substance obtained as a result is passed through a further line 7 in a dryer 8 , in which the remaining moisture is removed and from which the dry, solid end product can be removed as a high-quality natural fertilizer, which is more liquid due to the lack of it Shares now have a much smaller footprint and which is also easy to handle and pack because of its dry consistency.
Die in der Zentrifuge 6 abgetrennte Flüssigkeits substanz wird über eine Rohrleitung 9 in einen Zwischenspeicher 10 und von dort weiter in einen Ver dampfer 11 geleitet. In letzterem wird bei Unterdruck Wasser verdampft, welches über eine weitere Leitung 12 in einen Kondensator 13 gelangt, wo es erneut konden siert und von wo aus es über eine Pumpe 14 und eine weitere Leitung 15 dem natürlichen Wasserkreislauf, d. h. in diesem Fall einem Gewässer, zugeführt wird. Zuvor wird dem Kondensat aus einem Vorratsbehälter 16 Schwefelsäure (H2SO4) zugemischt, um noch im Kondensat enthaltenes Ammoniak (NH3) zu neutralisieren. Das Ammoniak wird dabei in Ammoniumsulfat (NH4 2 SO4 über führt, das in einem nachfolgenden Behälter 17 ausfällt und das an dieser Stelle entnommenen oder als praktisch unschädliches Medium zusammen mit dem Kondenswasser in das Gewässer eingeleitet werden kann.The separated in the centrifuge 6 liquid substance is passed through a pipe 9 into a buffer 10 and from there to a steamer 11 Ver. In the latter, water is evaporated at negative pressure, which passes via a further line 12 into a condenser 13 , where it condenses again and from where it flows through a pump 14 and a further line 15 to the natural water cycle, ie in this case a body of water, is fed. 16 Sulfuric acid (H 2 SO 4 ) is previously mixed into the condensate from a storage container in order to neutralize ammonia (NH 3 ) still contained in the condensate. The ammonia is in ammonium sulfate (NH 4 2 SO 4 leads over, which fails in a subsequent container 17 and which can be removed at this point or as a practically harmless medium together with the condensed water can be introduced into the water.
Die im Kondensator zurückgewonnene Kondensationswärme wird mittels einer Wärmepumpe 18 in ihrer Temperatur so weit angehoben, daß diese Energie, über eine weitere Leitung 19 in den Verdampfer 11 gefördert, dort die im Verdampfer enthaltene Wassermenge auf einem Temperatur niveau hält, bei dem die optimalen Bedingungen für eine intensive Verdampfung gegeben sind. Hierbei ist ein Drosselventil 20 für das Kältemittel vorgesehen.The condensation heat recovered in the condenser is raised in temperature by means of a heat pump 18 to such an extent that this energy, conveyed via a further line 19 into the evaporator 11 , keeps the amount of water contained in the evaporator at a temperature at which the optimal conditions for there is an intensive evaporation. Here, a throttle valve 20 is provided for the refrigerant.
Die Erzeugung des benötigten Unterdrucks im Verdampfer 11 erfolgt, zumindest in der Hochlaufphase, über eine Vakuumpumpe 21, später wird dieser Unterdruck von der Wasserpumpe 14, die das Kondensat abpumpt, erzeugt. Der erwähnte Zwischenspeicher 10 dient der Regulierung der Wasserzufuhr in den Verdampfer 11, wobei das Wasser entsprechend der sich einstellenden Verdampfungsrate nachgeliefert wird. Ein Motor 22 dient sowohl zum An trieb der im System enthaltenen Pumpen, die in den ent sprechenden Leitungswegen vorgesehen und in der Zeich nung eingetragen sind, hier aber nur zum Teil explizit erwähnt werden, als auch der Zentrifuge 6. Er wird im wesentlichen mit dem im Speicher 4 aufgefangenen Methangas betrieben, das diesem über eine Leitung 23 zugeführt wird. Ein etwaig auftretendes Energiedefizit wird mittels Fremdenergie, in diesem Fall Erdgas, aus geglichen, das über eine Leitung 24 von außen zugeführt werden kann.The vacuum required in the evaporator 11 is generated, at least in the run-up phase, by means of a vacuum pump 21 ; later this vacuum is generated by the water pump 14 , which pumps out the condensate. The aforementioned buffer store 10 serves to regulate the water supply to the evaporator 11 , the water being replenished in accordance with the evaporation rate that arises. A motor 22 serves both to drive the pumps contained in the system, which are provided in the corresponding conduit paths and are entered in the drawing, but are only partially mentioned here explicitly, as well as the centrifuge 6 . It is operated essentially with the methane gas collected in the store 4 , which is supplied to it via a line 23 . Any energy deficit that occurs is compensated for using external energy, in this case natural gas, which can be supplied from the outside via a line 24 .
Erwähnt sei abschließend noch, daß die Abwärme des Motors 22 über eine weitere Leitung 25 dem Trockner 8 zugeleitet wird und daß der in diesem entstehende Was serdampf in einem zweiten Kondensator 26 aufgefangen wird. Von diesem wird die kondensierte Flüssigkeit in den Zwischenspeicher 10 gefördert, während die Abluft über eine Leitung 27 durch den Behälter 1 ins Freie geleitet wird, wobei sie die im Behälter 1 enthaltene Gülle erwärmt und so den Prozeß der Methangasbildung zusätzlich begünstigt.Finally, it should be mentioned that the waste heat from the motor 22 is fed to the dryer 8 via a further line 25 and that the water vapor generated in this is collected in a second condenser 26 . From this, the condensed liquid is conveyed into the intermediate storage 10 , while the exhaust air is passed via a line 27 through the container 1 to the outside, whereby it heats the slurry contained in the container 1 and thus additionally promotes the process of methane gas formation.
