Abstract
Description
Die vorliegende Erfindung betrifft ein Verfahren zur Vergärung verrottbarer Masse.The present invention relates to a fermentation process rotting mass.
Das bisherige bekannte Verfahren gemäß Patent DE 41 11 204 des vorliegenden Anmelders betrifft ein Verfahren zur Erzeugung von Humusdünger in einer aeroben Rotte mit o.a. Reststoffen.The previous known method according to patent DE 41 11 204 des the present applicant relates to a method for producing Humus fertilizer in an aerobic crop with the above Residues.
Der dabei gewonnene Humusdünger kann auch in einem Hochtempera turofen zu Biogas verwertet werden, wenn man vorher diese Masse auf unter 20% Gew. Feuchte getrocknet hat.The humus fertilizer obtained can also be used in a high temperature turofen to be used for biogas if you have this mass beforehand has dried to less than 20% by weight of moisture.
Zur Trocknung benutzt man die Wärme aus einem nachgesetzten Biogas-BHKW.The heat from a subsequent one is used for drying Biogas CHP.
Vorbekannt ist es nach dem obigen Patent, daß man in Form von halbfesten Großpellets mit 50-50% Feuchte in einer klimage steuerten Kammer eine aerobe Rotte vornimmt. Die Vorteile der Großpelletsnutzung und des gesamten bisherigen Patentsystems wurden dort bereits erläutert (große Menge Biomasse auf kleiner Fläche, gesteuertes Rotteklima, kein Umrühren, kurze Rottezeit etc.).It is previously known from the above patent that in the form of semi-solid large pellets with 50-50% moisture in one climate controlled chamber makes an aerobic rotting. The advantages of Large pellet use and the entire previous patent system were already explained there (large amount of biomass on small Area, controlled rotting climate, no stirring, short rotting time Etc.).
Ferner ist die Biogaserzeugung in Hochtemperaturöfen bekannt. Das Vergasungsbrenngut muß stückartig sein. Die Großpellets er füllen diese Voraussetzung ohne zusätzlichen Aufwand.Biogas production in high-temperature furnaces is also known. The gasification combustible must be in pieces. The large pellets fulfill this requirement without additional effort.
Aufgabe der Erfindung ist es, das vorbekannte Verfahren weiter zu entwickeln und zu verbessern, möglichst eine Verkürzung der Rottezeit zu erreichen.The object of the invention is to continue the known method to develop and improve, if possible shortening the To reach rotting time.
Diese Aufgabe wird durch das Verfahren nach dem Anspruch 1 ge löst.This object is achieved by the method according to claim 1 solves.
Vorteilhaft und neu ist, daß man Großpellets dieser speziellen Art als festen Stoff mit einem Lochkanal durch die Längsachse und gewellter Oberfläche gut vorkonditioniert für eine optimale Rotte, ideal einem anaeroben Rotteprozeß unterzieht bei gleich zeitiger Biogasgewinnung, welches rottebedingt auch noch einen hohen Methangasgehalt aufweist. Dies Methangas kann einem Bio gas-Dieselmotor direkt zugeführt werden bzw. komprimiert in Be hältern in vielen anderen Bereichen verwendet werden. In diesem vor gen. Neuheit-System entfällt also die Gaswäsche und der Hochtemperaturofen. Die Biomasse braucht nicht getrocknet zu werden (kein Thermoenergieverlust) und es verbleibt eine vergo rene Biomasse (40-50% statt 1-3%) als fester Humusdünger, welcher bodenverbessernd wirkt und nicht ausgewaschen wird noch Grundwasser nitrifiziert und/oder als normaler Brennstoff ver wertet wird.It is advantageous and new that large pellets of this special Kind as a solid material with a perforated channel through the longitudinal axis and corrugated surface well preconditioned for optimal Rotting, ideally undergoes an anaerobic rotting process at the same time early biogas production, which due to rot also one has a high methane gas content. This methane gas can be a bio gas diesel engine can be fed directly or compressed into Be can be used in many other areas. In this Before the novelty system, there is no gas scrubbing and High temperature furnace. The biomass does not need to be dried be (no thermal energy loss) and there remains a forgotten Renewable biomass (40-50% instead of 1-3%) as a solid humus fertilizer, which improves soil and is not washed out yet Groundwater nitrified and / or ver as normal fuel is evaluated.
Der höhere Methangasanteil ergibt auch einen höheren Nutzeffekt mit weniger Aufwand und auch weniger Motorendauerbelastungspro bleme und macht Zündstrahlverbesserung durch normales Erdgas oder Leichtöl überflüssig.The higher methane gas content also results in a higher efficiency with less effort and also less engine continuous load pro bleme and improves the ignition jet through normal natural gas or light oil unnecessary.
Die Möglichkeit der Nutzung des gewonnenen Biogases auf den Be trieb selbst durch ein Biogas-Diesel-BHKW, macht den Prozeß selbst energieautark, sowie den gesamten Betrieb elektrisch und thermisch autark.The possibility of using the biogas obtained on the Be powered by a biogas diesel CHP, does the process self-energy self-sufficient, as well as the entire operation electrically and thermally self-sufficient.
Mit Kosten von 10-12 pf./kWh el. ist dieses System insgesamt eines der wenigen alternativen Energieerzeugungsanlagen, welche auf Dauer rentabel sind und auch noch Reststoffe aller Art be seitigen bzw. ökonomisch und ökologisch positiv nutzen.With a cost of 10-12 pf./kWh el., This system is total one of the few alternative energy generation plants which are profitable in the long term and also all kinds of residues mutual or economically and ecologically positive use.
Die Biomasseerzeugung und Einlagerung in einen gasdichten Reak tor kann in einer 8-Stunden-Arbeitsschicht erfolgen, aber über ein Gasreservoir kann das Biogas BHKW 24 Stunden 365 Tage/Jahr laufen.Biomass production and storage in a gas-tight reak can be done in an 8-hour work shift, but over the biogas CHP can operate a gas reservoir 24 hours a day, 365 days a year to run.
Sollte Bioprozeß stoppen, zusammenbrechen, weil z. B. Fremdstof fe (Reinigungsmittel, chemische Stoffe) in der Rottemasse sind, so braucht man nur einige Stunden, um den Bioreaktor zu entlee ren, neu zu befüllen, den Rotteprozeß neu zu starten und nur einen Tag, um den Biogasprozeß neu zu starten. Should bioprocess stop, collapse because e.g. B. foreign matter fe (cleaning agents, chemical substances) are in the red mass, it only takes a few hours to empty the bioreactor to refill, restart the rotting process and just a day to restart the biogas process.
Andere Verfahren brauchen-dazu ein bis zwei Wochen, müssen ei nen großen Behälter reinigen und erzeugen in der Zeit kein Gas! In diesem neuen Verfahren haben wir 4-5 Bioreaktionskammern (5 Arbeitstage).Other procedures take a week or two to do this Clean a large container and do not generate gas in time! In this new procedure we have 4-5 bioreaction chambers (5th Working days).
Unter Verzicht auf voll anaerobe Durchrottung (ökonomischer Grund) ist ein 4-5 Tagesrhythmus möglich, d. h. in 8 Stunden an einem Arbeitstag entleeren, mit neuer Biomasse befüllen und der Rotteprozeß starten, welcher nach 6-8 Stunden beginnt und dann an den folgenden 4-6 Tagen vergären und Gas erzeugen. Die Rot tezeit ist auf 4-5 Arbeitstage verkürzbar.Without fully anaerobic eradication (more economical Reason), a 4-5 daily rhythm is possible, d. H. in 8 hours empty one working day, fill with new biomass and the Start the rotting process, which starts after 6-8 hours and then ferment for the next 4-6 days and generate gas. The red The time can be reduced to 4-5 working days.
Etwas Wärme vom BHKW wird nur in den ersten 6 bis 8 Stunden der Rotte benötigt, da sich dann Eigenwärme entwickelt hat.Some heat from the CHP will only be felt in the first 6 to 8 hours Rotte needed, because then own heat has developed.
Der gasdichte Biomasse-Reaktor besitzt die Vorrichtungen, die in Fig. 1 angegeben sind.The gas-tight biomass reactor has the devices shown in FIG. 1.
Insbesondere bei der Einmischung von industriellen und tieri schen Reststoffen ist die besondere Rotteprozeßsteuerung not wendig und die vorliegende Erfindung bzw. macht die Verwertung von vor gen. Reststoffen ohne weiteres erst möglich (z. B. Schlachtereiabfälle, verdorbene Nahrungsmittel, Fischabfälle, salmonellenverseuchte Produkte bzw. alles was rottet). Die Hy gienisierung findet beim Rotteprozeß statt.Especially when interfering with industrial and tieri special waste control is necessary manoeuvrable and the present invention or makes the recovery from the above-mentioned residues without further ado (e.g. Slaughterhouse waste, spoiled food, fish waste, products contaminated with salmonella or everything that rots). The hy Engineering takes place during the rotting process.
Die Biogasausbeute ist in Co-Fermentation mit diesen vor gen. sehr bioreaktiven Reststoffen noch besser, bzw. dieses neue Technik/System macht dies erst möglich.The biogas yield is in co-fermentation with these before. very bioreactive residues even better, or this new one Technology / system makes this possible.
Beim Einsatz in kommunalen Kläranlagen ergibt sich eine gravie rende Neuheit:There is gravity when used in municipal wastewater treatment plants novelty:
Ohne Vollklärung wird der Klärschlamm über eine neuartige Sieb technik heraussepariert und mit anderen Reststoffen gemischt, dem vor genannten anaeroben Rotteprozeß unterzogen und daraus Biogas gewonnen zur Verwendung wie vor genannt. Bei einem BHKW-Einsatz kann dann Elektrizität und Wärmeenergie wieder an die Kommune zurückgeführt werden.Without clarification, the sewage sludge is passed through a new sieve technology separated and mixed with other residues, subjected to the aforementioned anaerobic rotting process and from it Biogas obtained for use as mentioned before. At a CHP can then be used to return electricity and thermal energy to the Commune to be returned.
Entscheidend neu dabei ist, daß man schon nur angerotteten Klärschlamm verarbeiten kann und nicht erst voll ausgegorenen. The crucial thing here is that you are already just rotted Sewage sludge can process and not fully fermented.
Der Biowert der Masse ist höher und es wird ca. 1/3 Zeit und Volumen eines üblichen Klärprozesses eingespart.The bio value of the mass is higher and it will be about 1/3 of the time Volume of a usual clarification process saved.
Es gibt erste Anlagen mit Hochtemperatur-Vergasungsofen mit folgenden Biogas-BHKW, aber dabei geht wie schon genannt, die gesamte thermische Energie für das Trocknen auf unter 20% Feuchte verloren. Bei dem neuen System entfällt bekanntlich der vor gen. Ofen.There are first plants with a high-temperature gasification furnace following biogas CHP, but as already mentioned, the total thermal energy for drying to below 20% Moisture lost. As is well known, the new system does not in front of the oven.
Dieses neue System erlaubt es, den Klärschlamm zum Vorteil der Verursacher zu nutzen, statt nur zu beseitigen.This new system allows sewage sludge to be used for the benefit of Using polluters instead of just eliminating them.
Vorhandene Kläranlagen können mit dieser Technik mehr Abwasser verarbeiten bzw. neue kleiner gestaltet werden.Existing sewage treatment plants can use this technology to produce more wastewater process or make new smaller.
Dies neue System erlaubt es, Industriebetriebe über die Verwer tung der eigenen Abfälle energieautark zu machen, z. B. Schlach tereiabfälle, Brennerei und Brauerei.This new system allows industrial companies to recycle to make your own waste energy self-sufficient, e.g. B. Schlach waste, distillery and brewery.
Immer verbleiben Großpellets, welche staubarm transportiert werden können zur Humusdüngerverwertung oder einfachen Verbren nung.Large pellets always remain, which are transported with little dust can be used for humus fertilization or simple burning nung.
Unter bestimmten Voraussetzungen sind die Großpellets als Hu musdünger im Landschafts- und Gartenbau verwendbar und ersetzen Torf (erhalten Naturlandschaften), d. h. Rest- und Abfallstoffen hygienisiert, ersetzen Torf.Under certain conditions, the large pellets are called Hu can be used and replaced in landscaping and horticulture Peat (preserve natural landscapes), d. H. Residual and waste materials sanitized, replace peat.
Diese erfindungsgemäß eingesetzten Großpellets mit den mittigen Löchern lassen sich in der Topfpflanzenzucht verwenden. Ohne daß noch ein Plastiktopf verwendet werden muß, sät, setzt man den Pflanzling mit etwas zerriebener Masse ins Loch. Er findet sehr gute Wachstumsbedingungen vor. Plastiktöpfe entfallen.These large pellets used according to the invention with the middle Holes can be used in potted plants. Without that a plastic pot must still be used is sown the plant with a little grated mass into the hole. He thinks very good growing conditions. There are no plastic pots.
Da in einer gasdichten Kammer Feststoffvergärung gemacht wird, entsteht hier absolut keine Emission.Since solid fermentation takes place in a gas-tight chamber, there is absolutely no emission here.
Das Biogas-Diesel-BHKW hat eine übliche Dieselmotorabgasfilte rung gemäß gesetzlichen Bestimmungen der TA-Luft. Die Großpel lets als Feststoff sind geruchsarm und ohne Geruchsbelästigung für Dritte auf dem Acker ausbringbar. Bei der Massentierhaltung entfällt die Geruchsbelästigung der Gülle bei der Lagerung und Ausbringung. Eine Zwischenlagerung der Großpellets ist unpro blematisch kostengünstiger in einer hohen Halle möglich, statt in Rundbehältern mit Rührproblemen. Großpellets sind mit Schau felladern, Frontladern bewegbar und auch die Ausbringungstech nik ist sauberer und kostengünstiger. Die Großpellets sind staubarm transportfähig auch für dezentrale Verwendung gut ge eignet.The biogas diesel CHP has a common diesel engine exhaust filter tion in accordance with the legal provisions of TA-Luft. The great furs lets as a solid are low-odor and without odor nuisance spreadable for third parties in the field. In factory farming there is no smell of slurry during storage and Output. Interim storage of the large pellets is unpro possible in a high hall, rather than in a schematic way in round containers with stirring problems. Large pellets are on display Felladern, front loaders movable and also the spreading tech nik is cleaner and cheaper. The large pellets are Dust-free transportable, also for decentralized use is suitable.
In der vorliegenden Erfindung kann man mit diesem neuen System bestimmte Rottemassen wie z. B. Stroh (jährlich nachwachsend, kein ökonomischer Verlust) mit Brennereireststoff (dito Braue rei) dem Biovergasungsrotteprozeß unterziehen und Methangas ge winnen und aber die verbliebenen vergorenen Großpellets als Rinderfutter so oder in einer Kraftfuttermischung verwenden und nicht als Humusdünger oder normalen Brennstoff.In the present invention one can use this new system certain masses of rot, e.g. B. straw (renewable annually, no economic loss) with distillery residues (same as brow rei) undergo the bio-gasification rotting process and methane gas win and but the remaining fermented large pellets as Use beef feed in this way or in a concentrate mix and not as humus fertilizer or normal fuel.
Frisches Grünfutter wird mit Stroh gemischt, vergoren, biover gast und ist wie vor gen. als Futter verwendbar.Fresh green fodder is mixed with straw, fermented, biover guest and can be used as feed as before.
Sog. Schlempe von Brennerei/Brauerei wird z.Z. flüssig als Fut ter verwertet.So-called. Still from the distillery / brewery is currently liquid as fut ter recycled.
Man gewinnt Biogas und behält trotzdem noch Futter in Pellet form aber nur 40-50% der Ausgangsmasse.You win biogas and still keep feed in pellet shape but only 40-50% of the initial mass.
Insbesondere wird zu den obigen erfindungsgemäßen Verfahrens- und Vorrichtungsmerkmalen auf die Blockdiagramme gemäß Fig. 2 und 3 verwiesen.In particular, reference is made to the block diagrams according to FIGS. 2 and 3 for the above method and device features according to the invention.
