Abstract
Description
Die vorliegende Erfindung betrifft eine Vorrichtung und ein Verfahren zur Vergasung organischer Substanzen, insbesondere Holz.The The present invention relates to an apparatus and a method for the gasification of organic substances, in particular wood.
Bei der Holzvergasung wird durch Pyrolyse oder Teilverbrennung unter Luftmangel aus Holz brennbares Holzgas gewonnen. Bekannt sind Festbett-Vergaser im Gegenstrom- und Gleichstromverfahren, Wirbelschicht-Vergaser sowie Flugstrom-Vergaser.at the wood gasification is by pyrolysis or partial combustion under Lack of air made of wood combustible wood gas. Are known fixed bed carburetor in countercurrent and DC process, fluidized bed gasifier as well as entrainment gasifier.
Offenbarung der ErfindungDisclosure of the invention
Bei den aus dem Stand der Technik bekannten Vorrichtungen und Verfahren zur Holzvergasung sind die Anteile fester Stoffe wie Asche, Holzkohle und dergleichen sowie großmolekulare, teils aromatische Kohlenwasserstoffe (Teere) des entstehenden Holzgases für eine Verwendung beispielsweise in einer Brennkraftmaschine oftmals zu hoch.at known from the prior art devices and methods for wood gasification are the proportions of solids such as ash, charcoal and like as well as large molecular, partly aromatic hydrocarbons (tars) of the resulting wood gas for one Use for example in an internal combustion engine often too high.
Eine Aufgabe der vorliegenden Erfindung ist es daher, eine Vorrichtung und ein Verfahren zur Holzvergasung anzugeben, die eine Verringerung der Anteile fester Stoffe und Teere in dem Holzgas ermöglichen.A Object of the present invention is therefore an apparatus and to provide a method of wood gasification which will reduce the Allow shares of solids and tars in the wood gas.
Dieses Problem wird gelöst durch eine Vorrichtung zur Vergasung organischer Substanzen, insbesondere Holz, wobei die Vorrichtung eine Vergasungsstufe mit einer Umwälzeinrichtung, in der die Vergasung im Wesentlichen erfolgt, umfasst. Die Umwälzeinrichtung kann eine drehbare Trommel oder Umwälzmittel wie rotierend gelagerte Leisten oder dergleichen umfassen. Die Umwälzmittel wälzen die organischen Substanzen gleichmäßig oder intermittierend um.This Problem is solved by a device for the gasification of organic substances, in particular Wood, the apparatus comprising a gasification stage with a circulation device, in which the gasification is carried out substantially comprises. The circulation device can be a rotatable drum or agitating such as rotating Bars or the like include. The circulating means roll the organic substances evenly or intermittently around.
Vorzugsweise ist vorgesehen, dass die drehbare Trommel über ihren Umfang verteilt Öffnungen zur Ableitung von Asche umfasst.Preferably is provided that the rotatable drum distributed over its circumference openings for Derivation of ash includes.
Die Vergasungsstufe umfasst vorzugsweise eine Zuführeinrichtung zum Einbringen der organischen Substanz, wobei die Zuführeinrichtung bevorzugt eine Schleuse umfasst. Die Zuführeinrichtung umfasst bevorzugt eine Zuführöffnung, die in etwa in der Drehachse der Trommel angeordnet ist. Die Trommel umfasst bevorzugt eine Schüttung eines für die Vergasung der organischen Substanz katalytisch wirkenden Stoffes.The Gasification stage preferably comprises a feed device for introduction the organic substance, wherein the feed preferably a Includes lock. The feeder comprises preferably a feed opening, which is arranged approximately in the axis of rotation of the drum. The drum preferably comprises a bed one for the Gasification of the organic substance of catalytically active substance.
Vorzugsweise ist vorgesehen, dass die Vorrichtung eine Gasreinigungsstufe umfasst. Durch die Gasreinigungsstufe kann die Qualität des Holzgases nach der Holzvergasung in der Vergasungsstufe weiter verbessert werden.Preferably it is envisaged that the device comprises a gas purification stage. Through the gas purification stage, the quality of the wood gas after the wood gasification be further improved in the gasification stage.
Die Gasreinigungsstufe umfasst bevorzugt eine Umwälzeinrichtung mit einer Schüttung eines für die Vergasung der organischen Substanz katalytisch wirkenden Stoffes. Die Umwälzeinrichtung kann ebenso wie bei der Vergasungsstufe eine drehbare Trommel rotierend gelagerte Leisten oder dergleichen umfassen.The Gas purification stage preferably comprises a circulation device with a bed of a for the Gasification of the organic substance of catalytically active substance. The circulation device can rotate as well as in the gasification stage, a rotatable drum include stored strips or the like.
Vorzugsweise ist vorgesehen, dass die Schüttung der Gasreinigungsstufe und/oder der Vergasungsstufe im wesentlichen Dolomit oder Olivin umfasst. Dolomit bzw. Olivin wirkt katalytisch auf die Holzvergasung und ist zudem günstig und leicht zu handhaben. Die Qualität des Holzgases wird durch die Verwendung einer Schüttung von Dolomit oder Olivin verbessert. Ins besondere wird der Anteil fester Stoffe und Teere in dem Holzgas weiter verringert.Preferably is provided that the bedding the gas purification stage and / or the gasification stage substantially Includes dolomite or olivine. Dolomite or olivine acts catalytically on the wood gasification and is also cheap and easy to handle. The quality of the wood gas is produced by using a bed of Dolomite or olivine improved. In particular, the proportion of solids and tars in the wood gas further reduced.
Unterhalb der Trommel der Gasreinigungsstufe ist bevorzugt eine Zufuhr für Rohgases aus der Vergasungsstufe sowie eine Zufuhr von Luft oder Sauerstoff und oberhalb der Trommel ein Abzug des Gas-Endproduktes angeordnet. Die drehbare Trommel der Gasreinigungsstufe umfasst vorzugsweise über ihren Umfang verteilt Öffnungen zur Ableitung von Asche und dergleichen aus dem Trommelinneren.Below The drum of the gas purification stage is preferably a feed for raw gas from the gasification stage and a supply of air or oxygen and disposed above the drum, a deduction of the gas end product. The rotatable drum of the gas purification stage preferably comprises over its Circumference distributes openings for discharging ash and the like from the inside of the drum.
Das eingangs genannte Problem wird auch gelöst durch ein Verfahren zur Vergasung organischer Substanzen, insbesondere Holz, umfassend die Verfahrensschritte
- – Vergasung der organischen Substanz zu einem Rohgas in einer sich drehenden Trommel;
- – Reinigung des Rohgases in einer katalytisch arbeitenden Reinigungsstufe.
- - Gasification of the organic substance to a raw gas in a rotating drum;
- - Purification of the raw gas in a catalytic purification stage.

Die
Vorrichtung gemäß
Statt einer Dolomit-Schüttung können auch andere, für die Pyrolyse von Holz wirksame katalytische Substanzen verwendet werden. Hierzu eignet sich insbesondere Olivin oder beispielsweise vernickelte Stahlkugeln bzw. Stahlkugeln mit hohem Nickelgehalt oder auch einfach nur Kalkstein.Instead of a dolomite bed can others too, for the pyrolysis of wood uses effective catalytic substances become. Olivine or, for example, is suitable for this purpose nickel-plated steel balls or steel balls with a high nickel content or just limestone.
