Description

SILO, VERFAHREN ZUM BEGASEN VON SCHÜTTGUT  SILO, METHOD FOR BEGANGING BULK

[0001] Die Beschreibung bezieht sich auf ein Silo und ein Verfahren zur Ausführung von Prozessen mit Gasen in Schüttgut. The description relates to a silo and a method for carrying out processes with gases in bulk.

[0002] In vielen industriellen und landwirtschaftlichen Bereichen wird Schüttgut durch Silos befördert oder in diesen gelagert. Das im Silo gelagerte Schüttgut kann dort platzsparend, trocken und geschützt gelagert werden. Zu einem späteren Zeitpunkt kann das Schüttgut aus dem Silo in vordefinierten Mengen entnommen werden. Darüber hinaus besteht die Möglichkeit, das Schüttgut im Silo zu behandeln. Beispielsweise kann das Schüttgut im Silo getrocknet werden. Gleiches gilt auch bei der Entnahme des Schüttgutes aus dem Silo. Nachteilig an dieser Vorgehensweise ist jedoch, dass hierfür zusätzliche Anlagen und Vorrichtungen außerhalb des Silos montiert werden müssen und das Silo nur als (Zwischen-) Lagerung des Schüttgutes dient. Bei bekannten Silos ist eine Behandlung des Schüttgutes im Silo nicht vorgesehen. Besonders bei Anwendungsfällen, bei denen das Schüttgut kontinuierlich in das Silo eingefüllt und aus diesem entnommen wird, kann eine Behandlung des Schüttgutes im Silo vorteilhaft sein. Dabei wird das Schüttgut beim„Durchfließen" des Silos behandelt. Beispielsweise kann feuchtes Schüttgut direkt im Silo getrocknet werden. Eine externe Vorrichtung zum Trocknen des Schüttgutes kann dadurch entfallen. Bei bekannten Silos kann das Silo während der Behandlung des Schüttgutes nicht zur (Zwischen-) Lagerung genutzt werden. In many industrial and agricultural areas bulk material is transported by silos or stored in these. The stored in the silo bulk material can be stored there space-saving, dry and protected. At a later date, the bulk material can be removed from the silo in predefined quantities. In addition, it is possible to treat the bulk material in the silo. For example, the bulk material can be dried in the silo. The same applies to the removal of the bulk material from the silo. A disadvantage of this approach, however, is that this additional equipment and devices must be mounted outside of the silo and the silo only serves as (intermediate) storage of the bulk material. In known silos a treatment of the bulk material in the silo is not provided. Especially in applications in which the bulk material is continuously filled into the silo and removed from this, a treatment of the bulk material in the silo can be advantageous. For example, moist bulk material can be dried directly in the silo, eliminating the need for an external device to dry the bulk material. In the case of known silos, the silo can not be used for (intermediate) treatment of the bulk material. Storage to be used.

[0003] Die der vorliegenden Erfindung zugrunde liegende Aufgabe besteht folglich darin, ein Silo und ein Verfahren bereitzustellen, die eine Behandlung des Schüttgutes im Inneren des Silos ermöglichen. Darüber hinaus kann es außerdem wichtig sein, eine Behandlung des Schüttgutes auch während des Befüllens und/oder der gleichzeitigen Entnahme von Schüttgut aus dem Silo zu ermöglichen. [0004] Die Aufgabe wird durch ein Silo nach Anspruch 1 und ein Verfahren nach Anspruch 7 gelöst. The object underlying the present invention is therefore to provide a silo and a method that allow treatment of the bulk material inside the silo. In addition, it may also be important to allow treatment of the bulk material during filling and / or the simultaneous removal of bulk material from the silo. The object is achieved by a silo according to claim 1 and a method according to claim 7.

[0005] Es wird ein Silo zum Begasen von Schüttgut beschrieben. Das Silo umfasst einen Behälter zur Aufnahme von Schüttgut mit einem Einlass und einem Auslass und einen Ventilschieber, der im Behälter zwischen dem Einlass und dem Auslass angeordnet ist und dazu ausgebildet ist, eine vordefinierte Menge an Schüttgut pro Zeiteinheit in Fließrichtung vom Einlass zum Auslass fließen zu lassen. Das Silo umfasst außerdem eine Gaseintrittsöffnung, die am Behälter zwischen dem Ventilschieber und dem Auslass angeordnet ist, und Gas im Wesentlichen gegen die Fließrichtung des Schüttguts durch den Behälter strömt. It is described a silo for gassing of bulk material. The silo comprises a container for receiving bulk material having an inlet and an outlet and a valve spool disposed in the container between the inlet and the outlet and configured to flow a predefined amount of bulk material per unit time in the flow direction from the inlet to the outlet to let. The silo further includes a gas inlet opening disposed on the container between the valve spool and the outlet, and gas flows substantially against the flow direction of the bulk material through the container.

[0006] Außerdem wird ein Verfahren zum Begasen von Schüttgut beschrieben. Das Verfahren umfasst die Schritte: Bereitstellen eines Silos nach den Ansprüchen 1 bis 6, Befüllen des Behälters mit Schüttgut über den Einlass, Betätigen des Ventilschiebers, damit eine vordefinierte Menge Schüttgut pro Zeiteinheit zum Auslass fließen kann und Begasen des Schüttgutes, wobei Gas über die Gaseintrittsöffnung in den Behälter gegen die Fließrichtung des Schüttguts durch den Behälter und das Schüttgut strömt sowie Entnehmen des Schüttgutes aus dem Behälter. In addition, a method for gassing of bulk material is described. The method comprises the steps of providing a silo according to claims 1 to 6, filling the container with bulk material via the inlet, actuating the valve spool so that a predefined amount of bulk material per unit time can flow to the outlet and gassing the bulk material, with gas passing through the gas inlet flows into the container against the flow direction of the bulk material through the container and the bulk material and removing the bulk material from the container.

[0007] Die Vorrichtung und das Verfahren werden nachfolgend anhand der Figuren näher erläutert. Die Figuren dienen zur Veranschaulichung grundlegender Aspekte, wobei nur solche Merkmale dargestellt sind, die hierfür notwendig sind. Die Figuren sind nicht notwendigerweise maßstabsgetreu, wobei aber gleiche Bezugszeichen gleiche oder ähnliche Komponenten mit jeweils gleicher oder ähnlicher Ausgestaltung oder Funktionsweise bezeichnen. The device and the method will be explained in more detail with reference to the figures. The figures serve to illustrate basic aspects, only those features are shown, which are necessary for this. The figures are not necessarily to scale, but like reference characters designate the same or similar components, each having the same or similar configuration or operation.

[0008] Figur 1 zeigt ein beispielhaftes Silo in einer Schnittansicht mit zwei Ventilschiebern. Figure 1 shows an exemplary silo in a sectional view with two valve spools.

[0009] Figur 2 zeigt zwei beispielhafte Ventilschieber in einer perspektivischen Ansicht. [0010] Figur 3 zeigt eine Schnittansicht des Silos nach Figur 1 mit vier Ventilschiebern. Figure 2 shows two exemplary valve spool in a perspective view. FIG. 3 shows a sectional view of the silo according to FIG. 1 with four valve slides.

[0011] Anhand der Figuren werden ein Silo, insbesondere ein Hochsilo oder ein Siloturm, und ein dazugehöriges Verfahren beschrieben, bei dem Schüttgut mit einem Gasgegenstrom beaufschlagt werden kann. Das Silo und das dazugehörige Verfahren können beispielsweise zur Gasreinigung von Aktivkohlefiltern, zur Trocknung von Hackschnitzeln, zur Kühlung von Schüttgut im Zuge der Wärmerückgewinnung und zur Kompostierung im Zusammenhang mit der Humuserzeugung eingesetzt werden. Außerdem kann das Silo zur Lagerung und Durchführung von verschiedensten Schüttgütern, beispielsweise Kohle, verwendet werden. Dabei können im Silo verschiedene industrielle Prozesse ablaufen. Im Silo kann beispielsweise Schüttgut gekühlt, erwärmt, getrocknet, kompostiert und torrefiziert werden. Es ist außerdem möglich, dass mehrere Prozesse parallel zueinander ablaufen. Darüber hinaus können beliebige Arten von Schüttgut, und auch Gemische aus diesen, im Silo mit dem hier beschriebenen Verfahren verarbeitet werden. In der nachfolgenden Beschreibung wird angenommen, dass kontinuierlich Schüttgut aus dem Silo entnommen und gegebenenfalls gleichzeitig auch wieder Schüttgut in das Silo nachgefüllt wird. Eine kontinuierliche Entnahme von Schüttgut aus dem Silo ist für die bestimmungsgemäße Funktion des Silos und des dazugehörigen Verfahrens nicht notwendig. A silo, in particular a high silo or a silo tower, and an associated method are described with reference to the figures, in which bulk material can be subjected to a gas counterflow. The silo and the associated method can be used, for example, for gas purification of activated carbon filters, for drying wood chips, for cooling bulk material in the course of heat recovery and for composting in connection with humus production. In addition, the silo for storage and implementation of various bulk materials, such as coal, can be used. In this case, various industrial processes can take place in the silo. In the silo, for example, bulk goods can be cooled, heated, dried, composted and torrefied. It is also possible that several processes run parallel to each other. In addition, any type of bulk material, and also mixtures of these, can be processed in the silo with the method described here. In the following description, it is assumed that bulk material is continuously removed from the silo and, if appropriate, bulk material is also replenished into the silo at the same time. A continuous removal of bulk material from the silo is not necessary for the intended function of the silo and the associated method.

[0012] In Figur 1 ist eine Schnittansicht eines beispielhaften Silos dargestellt. Das Silo umfasst einen Behälter 10, der eine beliebige Geometrie aufweisen kann. Der Behälter 10 kann beispielsweise rund, rechteckig, vieleckig oder oval sein. Der Behälter 10 kann aus einem beliebigen Material, beispielsweise aus Metall, Kunststoff, Keramik oder einem Verbundwerkstoff, hergestellt sein. Der Behälter 10 dient dazu, Schüttgut 20 aufzunehmen, zu lagern und letztendlich auch wieder abzugeben. In diesem Beispiel umfasst der Behälter 10 zumindest einen Einlass 11, der in diesem Beispiel an einer Oberseite des Behälters 10 angeordnet ist und zumindest einen Auslass 12, der an einer Unterseite des Behälters 10 angeordnet ist, wobei sich die Unterseite an der dem Einlass 11 entgegengesetzten Seite des Behälters 10 befindet. Im dargestellten Beispiel wirkt die Schwerkraft auf das Schüttgut 20 annähernd in Richtung des Auslasses 12. Das führt dazu, dass das Schüttgut 20 entlang einer Fließrichtung v unter Einwirkung der Schwerkraft vom Einlass 11 zum Auslass 12 fließt. Die Fließrichtung v ist im vorliegenden Beispiel annähernd vertikal, also gleich der Wirkrichtung der Schwerkraft. Über den Auslass 12 kann das Schüttgut 20 kontinuierlich und gleichmäßig aus dem Behälter 10 entnommen werden und von dort zur weiteren Verarbeitung befördert werden. Gemäß einem weiteren Beispiel des Silos kann das Schüttgut 20 auch in einer anderen Richtung als der Vertikalen fließen. In diesem Fall wird das Schüttgut 20 über ein Gebläse, eine Pumpe oder mit einer mechanischen Fördereinrichtung, beispielsweise einer Förderschnecke im Silo gefördert. FIG. 1 shows a sectional view of an exemplary silo. The silo comprises a container 10, which may have any geometry. The container 10 may be, for example, round, rectangular, polygonal or oval. The container 10 may be made of any material, such as metal, plastic, ceramic or a composite material. The container 10 serves to receive bulk material 20, to store and finally deliver again. In this example, the container 10 comprises at least one inlet 11, which in this example is arranged on an upper side of the container 10 and at least one outlet 12, which is arranged on an underside of the container 10, wherein the underside at the inlet 11 opposite Side of the container 10 is located. In the example shown, gravity acts on the bulk material 20 approximately in the direction of the outlet 12. This leads in that the bulk material 20 flows along a direction of flow v from the inlet 11 to the outlet 12 under the action of gravity. In the present example, the direction of flow v is approximately vertical, that is to say equal to the effective direction of gravity. Through the outlet 12, the bulk material 20 can be continuously and evenly removed from the container 10 and transported from there for further processing. According to another example of the silo, the bulk material 20 may also flow in a direction other than the vertical. In this case, the bulk material 20 is conveyed via a fan, a pump or with a mechanical conveyor, such as a screw conveyor in the silo.

[0013] Im Behälter 10 kann sich zumindest ein Ventilschieber 15 befinden, der zwischen dem Einlass 11 und dem Auslass 12 angeordnet ist und dazu ausgebildet ist, eine vordefinierte Menge an Schüttgut 20 pro Zeiteinheit in Fließrichtung v zum Auslass 12 fließen zu lassen. In Figur 1 weist der Behälter 10 zwei Ventilschieber 15 auf. Soll im Betrieb über den Auslass 12 Schüttgut 20 entnommen werden, so können die Ventilschieber 15 dazu dienen, das Schüttgut 20 kontinuierlich und gleichmäßig aus dem Behälter 10 zu entnehmen. Die Ventilschieber 15 können beispielsweise zumindest teilweise aus Metall, Kunststoff, Keramik oder einem Verbundwerkstoff bestehen. Auch die Verwendung von Nichteisenmetallen ist möglich. Aufgrund des erhöhten Verschleißes an den Ventil Schiebern 15 können die Ventilschieber 15 zusätzlich mit Auftrags- schweißungen versehen werden. Links und rechts von den Ventilschiebern 15 können sich mechanische Barrieren 17 befinden, die ein Durchfließen des Schüttguts abseits der Ventilschieber 15 verhindern. In the container 10, at least one valve spool 15 may be located, which is arranged between the inlet 11 and the outlet 12 and is adapted to let flow a predefined amount of bulk material 20 per unit time in the flow direction v to the outlet 12. In FIG. 1, the container 10 has two valve slides 15. If bulk material 20 is to be removed during operation via the outlet 12, then the valve slides 15 can serve to remove the bulk material 20 continuously and uniformly from the container 10. The valve spool 15 may, for example, at least partially made of metal, plastic, ceramic or a composite material. The use of non-ferrous metals is possible. Due to the increased wear on the valve slides 15, the valve spool 15 can be additionally provided with order welds. To the left and right of the valve slides 15 may be mechanical barriers 17, which prevent flow of the bulk material away from the valve slide 15.

[0014] Im dargestellten Beispiel in Figur 1 weist der Behälter 10 außerdem zumindest eine Gaseintrittsöffnung 13 auf, die in vertikaler Richtung zwischen den Ventilschiebern 15 und dem Auslass 12 angeordnet sein kann und ein Einströmen eines (theoretisch beliebigen) Gases 30 in den Behälter 10 ermöglichen soll. Von der Gaseintrittsöff- nung 13 strömt das Gas 30 zwischen den mechanischen Barrieren 17 und den Ventilschiebern 15 hindurch. Durch eine Rotationbewegung um einen einstellbaren Winkel in eine Richtung und dann zurück in die andere Richtung der Ventil Schieber 15 um eine Achse quer zur Fließrichtung v des Schüttgutes 20 (im vorliegenden Beispiel eine horizontale Achse) wird das Schüttgut 20 lokal aufgelockert und dosiert und fließt entgegengesetzt zu der Richtung der Gasströmung zwischen den mechanischen Barrieren 17 und den Ventilschiebern 15 hindurch (Gegenstrom). Während das Gas von unten nach oben gegen die Fließrichtung v des Schüttgutes 20 durch den Behälter 10 strömt, kann es zu Wechselwirkungen zwischen dem Gas 30 und dem Schüttgut 20 kommen. Sowohl das Gas 30 als auch das Schüttgut 20 können dadurch chemisch und/oder physikalisch verändert werden. Das Gas 30 entweicht anschließend über den Einlass 11 und/oder über eine oder mehrere separate Gasaustrittsöffnungen 14 aus dem Behälter 10. Das Gas 30 kann anschließend aufgefangen und regeneriert werden oder gegebenenfalls entsorgt werden. In the example shown in Figure 1, the container 10 also has at least one gas inlet opening 13 which can be arranged in the vertical direction between the valve spools 15 and the outlet 12 and allow a (theoretically arbitrary) gas 30 to flow into the container 10 should. From the gas inlet opening 13, the gas 30 flows between the mechanical barriers 17 and the valve slides 15. By a rotational movement about an adjustable angle in one direction and then back in the other direction of the valve slide 15 to a Axis transverse to the flow direction v of the bulk material 20 (in the present example, a horizontal axis), the bulk material 20 is loosened and dosed locally and flows opposite to the direction of gas flow between the mechanical barriers 17 and the valve spool 15 through (counterflow). While the gas flows from bottom to top against the flow direction v of the bulk material 20 through the container 10, interactions between the gas 30 and the bulk material 20 may occur. Both the gas 30 and the bulk material 20 can thereby be changed chemically and / or physically. The gas 30 then escapes via the inlet 11 and / or via one or more separate gas outlet openings 14 from the container 10. The gas 30 can then be collected and regenerated or possibly disposed of.

[0015] Im Falle einer Trocknung von Hackschnitzeln dient das Gas 30 dazu, den noch feuchten Hackschnitzeln Feuchtigkeit zu entziehen. Zu diesem Zweck kann warme, trockene Luft über die Gaseintrittsöffnung 13 in den Behälter 10 geleitet werden. Dabei nimmt das das Schüttgut 20 durchströmende Gas 30 vom Schüttgut 20 Feuchtigkeit auf. Die vom Gas 30 aufgenommene Feuchtigkeit wird mit dem Gas 30 durch und anschließend aus dem Behälter 10 befördert. Dieser Prozess kann auch mehrfach hintereinander durchgeführt werden. Dadurch kann ein höherer Trocknungsgrad erreicht werden. In the case of drying of wood chips, the gas 30 serves to extract moisture from the still moist chips. For this purpose, warm, dry air can be conducted via the gas inlet opening 13 into the container 10. In the process, the gas 30 flowing through the bulk material 20 receives moisture from the bulk material 20. The moisture absorbed by the gas 30 is carried with the gas 30 through and then out of the container 10. This process can also be carried out several times in succession. This allows a higher degree of drying can be achieved.

[0016] Figur 2 zeigt zwei verschiedene Beispiele von Ventil Schiebern 15 in perspektivischer Ansicht. Die Ventilschieber 15 können in den beschriebenen Beispielen Rohroder Vollprofile mit jeweils einer Längsachse 16 sein. Die Ventilschieber 15 können beispielsweise einen rechteckigen oder einen ovalen Querschnitt aufweisen, aber keinen kreisrunden Querschnitt. Im dargestellten Beispiel sind die Ventilschieber 15 derart im Behälter 10 angeordnet, dass die Längsachsen 16 annähernd orthogonal zur Fließrichtung v des Schüttgutes 20 liegt. Figure 2 shows two different examples of valve sliders 15 in a perspective view. The valve spool 15 may be in the examples described Rohroder solid sections, each having a longitudinal axis 16. The valve spool 15 may for example have a rectangular or an oval cross section, but no circular cross section. In the illustrated example, the valve spool 15 are arranged in the container 10 such that the longitudinal axes 16 is approximately orthogonal to the flow direction v of the bulk material 20.

[0017] Bei der Entnahme von Schüttgut 20 aus dem Behälter 10 kann es je nach Konsistenz und Zusammensetzung des Schüttgutes 20 zu einem Verklumpen (Klumpenbildung) des Schüttgutes 20 im Behälter 10 kommen. Dabei bilden sich im Schüttgut 20 größere Verbände, die nicht mehr durch die Ventilschieber 15 hindurch fließen können und daraufhin eine gleichmäßige und kontinuierliche Entnahme von Schüttgut 20 über den Auslass 12 des Behälters 10 nahezu unmöglich machen. Im dargestellten Beispiel können die Ventilschieber 15 deshalb im Betrieb um deren Längsachsen 16 oszillieren. Die Oszillationsbewegung kann durch eine geeignete Steuerung gesteuert werden. Es kann beispielsweise auf den Drehwinkel und die Drehgeschwindigkeit Einfluss genommen werden. Die Ventilschieber 15 können mithilfe der Steuerung darüber hinaus auch eine nichtoszillierende Bewegung ausführen. Dies hat den Effekt, dass ein Verklumpen des Schüttgutes 20 im Behälter 10 vermieden wird und/oder durch die Oszillationsbewegung bereits bestehende Verklumpungen wieder gelöst werden können. Für besonders starke Verklumpungen kann die Oszillationsbewegung auch zusätzlich verstärkt werden. Die Oszillationsbewegung stellt eine gleichmäßige und kontinuierliche Entnahmemöglichkeit über den Auslass 12 am Behälter 10 sicher und kann beispielsweise derart ausgestaltet sein, dass um die Längsachse 16, ein Gesamtwinkel von 120° eingeschlossen wird. Dies würde einer Drehung aus einer Ruhelage von +/- 60° entsprechen. Alternativ dazu können auch größere und kleinere Gesamtwinkel eingesetzt werden. When removing bulk material 20 from the container 10, it may, depending on the consistency and composition of the bulk material 20 to a lumping (lump formation) of the bulk material 20 in the container 10 come. This is formed in the bulk 20 larger dressings that can not flow through the valve spool 15 thereafter and then make a uniform and continuous removal of bulk material 20 via the outlet 12 of the container 10 almost impossible. In the example shown, the valve slide 15 can therefore oscillate in operation about their longitudinal axes 16. The oscillation movement can be controlled by a suitable controller. For example, it is possible to influence the angle of rotation and the rotational speed. The valve spool 15 can also perform non-oscillatory motion using the controller. This has the effect that clumping of the bulk material 20 in the container 10 is avoided and / or already existing clumps can be solved by the oscillation movement again. For particularly strong clumping the oscillation movement can be additionally strengthened. The oscillatory movement ensures a uniform and continuous removal possibility via the outlet 12 on the container 10 and can for example be designed such that is enclosed around the longitudinal axis 16, a total angle of 120 °. This would correspond to a rotation from a rest position of +/- 60 °. Alternatively, larger and smaller total angles can be used.

[0018] Darüber hinaus ist es außerdem möglich, dass die Ventilschieber 15 derart zueinander verdreht und auch gehalten werden, dass sich zwischen den Ventilschiebern 15 jeweils ein kleiner Spalt bildet. Dieser Spalt kann stufenlos eingestellt werden und so klein sein, dass kein Schüttgut 20 mehr an den Ventilschiebern 15 vorbeifließen kann. Die Ventilschieber 15 können folglich auch den Durchfluss von Schüttgut 20 zum Auslass 12 absperren. Moreover, it is also possible that the valve spool 15 are rotated and held each other such that forms a small gap between the valve spools 15 each. This gap can be adjusted continuously and be so small that no bulk 20 can flow past the valve spool 15. The valve spool 15 can consequently also block the flow of bulk material 20 to the outlet 12.

[0019] In Figur 3 ist ein weiteres Beispiel des Silos dargestellt. In diesem Beispiel weist das Silo vier Ventilschieber 15 auf. Je nach Anwendung kann die Zahl der Ventilschieber 15 variieren. Im dargestellten Beispiel sind die Ventilschieber 15 derart angeordnet, das die Längsachsen 16 der Ventilschieber 15 nebeneinander und parallel zueinander in einer annähernd horizontalen Ebene liegen. Eine Anordnung von mehreren Ventilschiebern 15 kann notwendige Antriebskräfte für die einzelnen Ventilschieber 15 verringern. Alternativ dazu ist es auch möglich, dass die Längsachsen 16 der Ventilschieber 15 nicht ausschließlich in einer Ebene liegen. In Figure 3, another example of the silo is shown. In this example, the silo has four valve spools 15. Depending on the application, the number of valve spool 15 may vary. In the illustrated example, the valve spool 15 are arranged such that the longitudinal axes 16 of the valve spool 15 are adjacent to each other and parallel to each other in an approximately horizontal plane. An arrangement of a plurality of valve spools 15 can reduce necessary drive forces for the individual valve spool 15. Alternatively, it is also possible that the longitudinal axes 16 of the valve spool 15 are not exclusively in a plane.

[0020] Der Behälter 10 kann in den genannten Beispielen ein Fassungsvermögen von 1- 2000 m3 aufweisen. Darüber hinaus kann das Silo Schüttgut 20 von einem Volumen zwischen 1 und 1000 m3 pro Stunde aufnehmen und/oder durch den Behälter 10 fördern. The container 10 may have a capacity of 1- 2000 m 3 in the examples mentioned. In addition, the silo may receive bulk 20 of a volume between 1 and 1000 m 3 per hour and / or through the container 10.

[0021] Ein mit dem beschriebenen Silo verwendetes Verfahren umfasst das Bereitstellen eines oben beschriebenen Silos, sowie das anschließende Befüllen des Behälters 10 mit Schüttgut 20 über den Einlass 11 und das Betätigen des zumindest einen Ventilschiebers 15, damit eine vordefinierte Menge Schüttgut 20 pro Zeiteinheit zum Auslass 12 fließen kann. Währenddessen erfolgt das Begasen des Schüttgutes 20, wobei Gas 30 über die Gaseintrittsöffnung 13 in den Behälter 10, gegen die Fließrichtung v des Schüttgutes 20 und hin zum Einlass 11 durch den Behälter 10 und folglich auch durch das Schüttgut 20 strömt. Außerdem umfasst das Verfahren das Entnehmen des Schüttgutes 20 aus dem Behälter 10. Die Entnahme des Schüttgutes 20 aus dem Behälter 10 kann gleichmäßig und kontinuierlich erfolgen. In einem Beispiel des Verfahrens kann der Ventilschieber 15 eine oszillierende Bewegung um die Längsachse 16 ausführen. Für die Zuführung des Gases 30 zum Behälter 10 kann dieses beispielsweise unter Druck oder unter Vakuum mit Hilfe eines Gebläses oder einer Pumpe durch den Behälter 10 gefördert werden. A method used with the silo described comprises providing a silo described above, and then filling the container 10 with bulk material 20 via the inlet 11 and the actuation of the at least one valve spool 15, so that a predefined amount of bulk material 20 per unit time Outlet 12 can flow. Meanwhile, the gasification of the bulk material 20 takes place, wherein gas 30 flows via the gas inlet opening 13 into the container 10, against the flow direction v of the bulk material 20 and towards the inlet 11 through the container 10 and consequently also through the bulk material 20. In addition, the method comprises the removal of the bulk material 20 from the container 10. The removal of the bulk material 20 from the container 10 can be uniform and continuous. In one example of the method, the valve spool 15 may perform an oscillating motion about the longitudinal axis 16. For the supply of the gas 30 to the container 10, this can be conveyed through the container 10, for example under pressure or under vacuum with the aid of a blower or a pump.

[0022] Das in den Beispielen beschriebene Gas 30 kann jedes beliebige Gas 30 und Gasgemisch sein. Beispielsweise kann das Gas 30 Umgebungsluft, Sauerstoff, ein Inertgas oder Wasserdampf sein. The gas 30 described in the examples may be any gas 30 and gas mixture. For example, the gas 30 may be ambient air, oxygen, an inert gas or water vapor.

[0023] Im Folgenden werden verschiedene Anwendungsmöglichkeiten des beschriebenen Silos und des dazugehörigen Verfahrens beispielhaft erklärt. [0024] In einem Beispiel kann beispielsweise eine Trocknung von Schüttgut 20 durchgeführt werden. Das Schüttgut 20 kann in diesem Fall Hackgut, insbesondere Waldhackgut sein. Das Waldhackgut kann Hackgut von erntefrischen Fichten inklusive grüner Nadeln und Rinde sein und eine Feuchtigkeit von ca. 65% aufweisen. In the following, various applications of the described silo and the associated method are explained by way of example. In one example, for example, a drying of bulk material 20 can be carried out. The bulk material 20 may in this case be wood chips, in particular wood chips. The wood chips can be wood chips from freshly harvested spruces including green needles and bark and have a moisture content of about 65%.

[0025] Das Hackgut kann unter Einsatz des Silos in ein Biomasse-Heizwerk geleitet werden. Dazu kann das Silo ein Betonsilo sein, wobei der Behälter 10 einen Durchmesser von ca. 6,5 m und ein Inhaltsvolumen von ca. 650 m3 aufweisen kann. Bei diesem Beispiel erfolgt der Austrag des Hackgutes aus dem Behälter 10 durch einen hydraulisch angetriebenen Oszillomaten. Dabei kann gleichzeitig trockene kalte Luft mittels eines Radialventilators durch den Behälter 10 gesaugt werden. The wood chips can be passed using the silo in a biomass heating plant. For this purpose, the silo may be a concrete silo, wherein the container 10 may have a diameter of about 6.5 m and a content volume of about 650 m 3 . In this example, the discharge of the wood chips from the container 10 by a hydraulically driven oscillator. At the same time dry cold air can be sucked through the container 10 by means of a centrifugal fan.

[0026] Zur Verarbeitung des beschriebenen Hackgutes wird der Behälter 10 des Silos beispielsweise mit Miscanthus bis zu einer Höhe von ca. 12 m gefüllt. Zusätzlich können 90 m3 Waldhack mit einem Feuchtegehalt von 65% Wasser eingefüllt werden. Anschließend kann ein- oder mehrmals Luft unter Einsatz des Radialventilators durch den Behälter 10 gesaugt werden. Die Luft kann trockene und kalte Luft mit geringer Feuchtigkeit sein. Die trockene Luft entzieht dem Miscanthus und dem Waldhackgut Feuchtigkeit. In einem Beispiel zur Verarbeitung des Hackgutes beträgt die Betriebszeit des Radialventilators ca. 70 Stunden und es wird eine Luftmenge von ca. 5000 m3/h durch den Behälter 10 gesaugt. Der Radialventilator kann dabei kontinuierlich oder in vorgegebenen Zeitfenstern betrieben werden. Nach der Verarbeitung des Hackgutes kann der Feuchtegehalt auf ca. 30 % gesunken sein. For processing the described wood chips, the container 10 of the silo is filled with miscanthus, for example, to a height of about 12 m. In addition, 90 m 3 of forest hack with a moisture content of 65% water can be filled. Subsequently, one or more times air can be sucked through the container 10 using the radial fan. The air can be dry and cold air with low humidity. The dry air removes moisture from the miscanthus and the wood chips. In an example for processing the wood chips, the operating time of the centrifugal fan is about 70 hours and it is an air quantity of about 5000 m 3 / h sucked through the container 10. The centrifugal fan can be operated continuously or in predetermined time windows. After processing the wood chips, the moisture content may have fallen to about 30%.

[0027] In einem weiteren Anwendungsbeispiel kann auch Schüttgut 20, insbesondere mineralisches Schüttgut 20 gekühlt werden. Insbesondere können Mineralien mit einer Temperatur von ca. 800 °C im Behälter 10 auf ca. 200 °C gekühlt werden. Zu diesem Zweck kann ein Behälter 10 mit einem Volumen von ca. 100 m3 eingesetzt werden. Anschließend wird mithilfe des Radialventilators Luft mit einer Temperatur von ca. 100 °C durch den Behälter 10 gedrückt. Die kühlere Luft strömt an den Mineralien vorbei und entzieht diesen Wärme. In der Folge kommt es zu einer Abkühlung der Mineralien. [0028] In einem anderen Anwendungsbeispiel kann auch Schüttgut 20, insbesondere in Form von Briketts gekühlt werden. Das beschriebene Silo und das zugehörige Verfahren gewährleisten eine materialschonende Verarbeitung des Schüttgutes 20. Im beschriebenen Beispiel werden die bruchempfindlichen Briketts mit einer Körnung von ca. 20 mm schonend behandelt und ihre ursprüngliche Körnung kann auch während der Verarbeitung erhalten werden. Die Briketts werden im Behälter 10 von 80 °C auf ca. 30 °C herunter gekühlt. Zu diesem Zweck wird ein Behälter mit einem Volumen von ca. 50 m3 eingesetzt und es werden ca. 10 m3/h Briketts durch den Behälter 10 geleitet. Während der Kühlung der Briketts wird der Behälter 10 kontinuierlich entleert und gleichzeitig kontinuierlich befüllt. Dadurch kann der Füllstand durch die Briketts im Behälter 10 konstant gehalten werden. In a further example of application also bulk material 20, in particular mineral bulk material 20 can be cooled. In particular, minerals can be cooled at a temperature of about 800 ° C in the container 10 to about 200 ° C. For this purpose, a container 10 with a volume of about 100 m 3 can be used. Subsequently, with the aid of the radial fan, air at a temperature of approximately 100 ° C. is forced through the container 10. The cooler air flows past the minerals and removes this heat. As a result, there is a cooling of the minerals. In another application example also bulk material 20, in particular in the form of briquettes can be cooled. The silo described and the associated method ensure material-friendly processing of the bulk material 20. In the example described, the brittle fracture-sensitive briquettes are treated with a grain size of about 20 mm gently and their original grain size can also be obtained during processing. The briquettes are cooled in the container 10 from 80 ° C to about 30 ° C down. For this purpose, a container with a volume of about 50 m 3 is used and about 10 m 3 / h briquettes are passed through the container 10. During the cooling of the briquettes, the container 10 is continuously emptied and simultaneously filled continuously. As a result, the level can be kept constant by the briquettes in the container 10.
