Abstract

Additional aeration of material to be composted, is carried out by thrusting aeration pipes into it. The pipes pass preferably through the outer walls of the chambers. An Independent claim is included for a drying screw system. A conveyor screw is located in a trough. The trough is heated externally by water or preferably thermal fluid (an oil). Several screws may be stacked, the end of one feeding the start of the next, below.

Description

Das Konglomerat, dessen Herstellung im Hauptpatent be­ schrieben ist, wird in Rottekammern mit ca. 50-70 m3 Inhalt, die an den Außenwänden innen einer Halle angeord­ net sind, eingetragen. Die Rottekammern werden von einer torähnlichen Vorrichtung abgeschlossen. Oben schließt die Kammer vorzugsweise eine Folie dicht ab. Innerhalb der Kammer oben, an der Außenwand, ist ein horizontales Ab­ zugsrohr angeordnet, das durch alle Kammern an der Außen­ wand verläuft und mit Klappen versehen ist, die bei of­ fener Kammer geschlossen werden. In der Außenwand der Halle und somit auch der Kammern sind Löcher angeordnet, durch die von außen Belüftungsrohre in das Material ein­ geschoben werden, die in Abständen mit Löchern und vorn mit einer Spitze versehen sind. Die Belüftungsrohre wer­ den mit hohem Druck beaufschlagt, wodurch sich die Luft explosionsartig im Material ausbreitet. Da der Sauer­ stoffverbrauch im Material hoch ist, wird kontinuierlich oder diskontinuierlich mit schwachem Druck Luft weiter zugeführt. Die Temperatur steigt nun auf ca. 75°C an. Auf dieser Höhe sollte sie zur Hygenisierung einige Zeit verbleiben. Die Belüftungsrohre werden nach außen­ gezogen und das Material in eine leere Kammer nebenan umgesetzt. Dieses Verfahren wiederholt sich, bis zu ei­ nem gewissen Trocknungsgrad. Wichtig ist aber nur, daß eine Hygenisierung erreicht ist, denn eine Nachtrock­ nung mit Abwärme ist vorm Brikettieren und Vergasen in einer Trocknungsschnecke möglich. Das Material wird dem weiteren Verarbeitungsgang, wie im Hauptpatent beschrie­ ben, zugeführt. Im Oberteil der Kammer entsteht keinerlei Druck, da das Abzugsrohr mit leichtem Unterdruck gefahren wird und die abgezogenen Gase und Dämpfe über einen Kompostfilter, an die Außenluft abgegeben werden.The conglomerate, the production of which is described in the main patent, is entered in rotting chambers with a content of approx. 50-70 m 3 , which are arranged on the outer walls inside a hall. The rotting chambers are closed by a gate-like device. The chamber preferably seals off a film at the top. Inside the chamber at the top, on the outer wall, a horizontal exhaust pipe is arranged, which runs through all the chambers on the outer wall and is provided with flaps that are closed in the open chamber. Holes are arranged in the outer wall of the hall and thus also the chambers, through which ventilation pipes are inserted into the material from the outside, which are provided with holes at intervals and with a tip at the front. The ventilation pipes are subjected to high pressure, causing the air to explode in the material. Since the oxygen consumption in the material is high, air is fed in continuously or discontinuously at low pressure. The temperature now rises to approx. 75 ° C. It should remain at this level for some time for hygenization. The ventilation pipes are pulled outwards and the material is transferred into an empty chamber next door. This process is repeated up to a certain degree of dryness. It is only important, however, that hygienization is achieved, because after-drying with waste heat is possible in a drying screw before briquetting and gasification. The material is fed to the further processing stage as described in the main patent. There is no pressure in the upper part of the chamber, since the exhaust pipe is driven with a slight negative pressure and the extracted gases and vapors are released to the outside air via a compost filter.
