Description

Beschreibung: Description:
„Verfahren und Vorrichtung zur Herstellung eines Kohlekuchens für die Verkokung""Method and device for producing a coal cake for coking"
Die Erfindung betrifft ein Verfahren zur Herstellung eines Kohlekuchens für die Verkokung, bei dem eine Kohleschüttung in einer Form durch Impulse auf die Kohle- schüttung einwirkender Hämmer verdichtet und zu einem Block verfestigt wird, sowie eine Vorrichtung zur Durchführung des Verfahrens.The invention relates to a method for producing a coal cake for coking, in which a coal bed is compacted in a mold by impulses acting on the coal pile hammers and solidified into a block, and an apparatus for performing the method.
In einem durch Benutzung bekannten solchen Verfahren werden zur Verdichtung der Kohleschüttung Fallhämmer eingesetzt. Der hierdurch erzielte Verdichtungsgrad und die Gleichmäßigkeit der Verdichtung sind in vielen Fällen nicht ausr- eichend. Insbesondere ist die Festigkeit des gebildeten Kohleformblocks oft zu gering, um ihn bruchsicher transportieren und in einen Verkokungsofen einführen zu können.In a known by use of such methods fall hammers are used to compress the coal bed. The resulting degree of compaction and the uniformity of compaction are in many cases not sufficient. In particular, the strength of the formed coal forming block is often too low to transport it unbreakable and to introduce into a coking oven can.
Der Erfindung liegt die Aufgabe zugrunde, das eingangs erwähnte Verfahren im Hinblick auf die Herstellung höher verdichteter, festerer Kohleformblöcke zu verbessern.The invention has for its object to improve the method mentioned above with regard to the production of higher-density, firmer coal form blocks.
Diese Aufgabe wird dadurch gelöst, dass auf die Kohleschüttung zusätzlich zu der Impulsbeaufschlagung durch die Hämmer ein Pressdruck ausgeübt wird.This object is achieved in that a compressive pressure is exerted on the coal bed in addition to the impulse by the hammers.
Die Hauptursache für die mangelnde Verdichtung und Verfestigung im Verfahren nach dem Stand der Technik liegt in der geringen Festigkeit sowie auch einer gewissen Elastizität der Kohleschüttung. Die kinetische Energie der Hämmer wird bei der Wechselwirkung mit der Kohleschüttung daher nur zum Teil zur Verformung der Kohlekörner und damit zur Verdichtung der Schüttung genutzt. Infolge eines elastischen Stoßanteils behält der Hammer einen beachtlichen Teil seiner kinetischen Energie und springt zurück. Indem die Kohleschüttung erfindungsgemäß zusätzlich unter Druckspannung steht, dadurch verfestigt und näher an der Elastizitätsgrenze ist, erhöht sich der beim Stoß übertragene Anteil plastischer, an den Kohlekörnern geleisteter Verformungsarbeit, was zu einem hohen Verdichtungsgrad führt. Insbesondere kommt es unter Druckspannung in verstärktem Maße zum Austritt von hygroskopisch gebundenem Wasser und Bitumenmaterial aus den Kohlekörnern. Sowohl das ausgetretene Wasser als auch das Bitumenmaterial wirken als Bindemittel, das einen zusätzlichen Beitrag zur Festigkeit des gebildeten Kohleformblocks liefert.The main reason for the lack of compaction and solidification in the process of the prior art is the low strength and also a certain elasticity of the coal bed. The kinetic energy of the hammers is therefore only partially used in the interaction with the coal bed for the deformation of the carbon grains and thus for the compaction of the bed. Due to an elastic shock component, the hammer retains a considerable part of its kinetic energy and springs back. According to the invention, since the coal charge is additionally under compressive stress, thereby solidified and closer to the elastic limit, the proportion of plastic deformation force transferred to the carbon particles during impact is increased, which leads to a high degree of compaction. In particular, it comes under pressure to a greater extent to the escape of hygroscopic bound water and bitumen material from the carbon grains. Both the leaked water and the bitumen material act as a binder providing an additional contribution to the strength of the formed coal forming block.
Vorzugsweise erfolgt die Pressung kontinuierlich während und zwischen den Übertragungen der Hammerimpulse. Bei ständig anliegender Druckspannung können in der Schüttung auch zwischen den Hammerimpulsen den Verdichtungsgrad erhöhende Umschichtungsvorgänge ablaufen.Preferably, the pressing takes place continuously during and between the transmissions of the hammer pulses. With constantly applied compressive stress, the degree of compaction can increase the degree of compaction in the bed between the hammer pulses.
Die Größe der Presskraft oder/und der Hammerimpulse kann veränderbar sein, z.B. entsprechend dem Ausmaß der bereits erreichten Verdichtung.The size of the pressing force and / or the hammer pulses may be variable, e.g. according to the extent of compression already achieved.
Während es möglich ist, die Presskraft über eine einzige, an verschiedenen Stellen durch Hämmer beaufschlagte Pressplatte auszuüben, sind in der bevorzugten Ausführungsform der Erfindung mehrere, ggf. eine Pressplatte umfassende Presselemente vorgesehen.While it is possible to exert the pressing force on a single, applied at various points by hammers pressure plate, in the preferred embodiment of the invention, several, optionally a pressing plate comprising pressing elements are provided.
Vorzugsweise decken die Presselemente wenigstens eine Seite einer quaderförmigen Schüttung vollständig oder nahezu vollständig ab.Preferably, the pressing elements completely or almost completely cover at least one side of a cuboid bulk.
Während Presselemente und Hämmer in unterschiedlichen Oberflächenbereichen auf die Schüttung einwirken könnten, übertragen in der bevorzugten Ausführungsform der Erfindung die Presselemente neben dem Pressdruck auch die Hammerimpulse auf die Schüttung.While pressing elements and hammers could act on the bed in different surface areas, transferred in the preferred embodiment of the invention, the pressing elements in addition to the pressing pressure and the hammer pulses on the bed.
Die Hämmer schlagen also auf die Presselemente auf, wobei vorzugsweise das Massenverhältnis von Presselement und Hammer derart gewählt ist, dass der Hammer seinen Impuls vollständig auf das Presselement überträgt, welches dann seinerseits in einem weitgehend unelastischen Stoß seinen Impuls an die Kohle- schüttung verliert, wobei die kinetische Energie des Hammers weitgehend in Ver- formarbeit an den Kohlekörnern der Schüttung umgewandelt wird. Bei dem Hammer kann es sich um einen hydraulisch angetriebenen Hammer handeln, wie er z.B. in der Bauindustrie bei Abrissarbeiten zum Zerstören von Beton verwendet wird. Möglich wäre aber auch der Einsatz pneumatischer, elektrischer oder in anderer Weise angetriebener Hämmer.The hammers strike therefore on the pressing elements, wherein preferably the mass ratio of pressing element and hammer is selected such that the hammer transmits its impulse completely to the pressing element, which then in turn loses its momentum in a largely inelastic shock to the coal, wherein The kinetic energy of the hammer is largely converted into deformation work on the carbon grains of the bed. The hammer may be a hydraulically powered hammer, such as used in the construction industry for demolition work to destroy concrete. But it would also be possible to use pneumatic, electric or otherwise driven hammers.
Die Presskraft lässt sich auf das Presselement z.B. über das Gehäuse einer den Hammer umfassenden Hammereinrichtung übertragen.The pressing force can be applied to the pressing element, e.g. transmitted via the housing of a hammer device comprising the hammer.
Die Presselemente einschließlich Gehäuse können entsprechend der erreichten Verdichtung nachführbar und darüber hinaus in solchem Umfang beweglich sein, dass durch Verschiebung genügend Platz zum Füllen der Form geschaffen werden kann.The pressing elements including housing can be tracked in accordance with the achieved compaction trackable and beyond to such an extent that by displacement enough space for filling the mold can be created.
Durch das erfindungsgemäße Verfahren und die erfindungsgemäße Vorrichtung ergibt sich eine Reihe weiterer Vorteile. Der erreichbare hohe Verfestigungsgrad erlaubt den Einsatz bisher nicht verwendbarer Kohlesorten. Insbesondere können vorerhitzte Kohle und mit Additiven, insbesondere Bindemitteln, gemischte Kohle eingesetzt werden. Das neue Verfahren eröffnet größere Spielräume, um auf sich ändernde Eigenschaften der Einsatzkohle zu reagieren. Die Verwendung den Ver- kokungsprozess beeinträchtigenden Wassers als Bindemittel lässt sich reduzieren. Wegen der hohen Verdichtung der Kohle, welche infolge plastischer Verformung der Kohlekörner über die Verdichtung in einer dichtest möglichen Kugelpackung hinausgehen kann, verbleibt während der Verkokung durch Crackprozesse entstehender Kohlenstoff größtenteils im Kohlekuchen und lagert sich nicht nachteilig an der Innenwand des Verkokungsofens an. Der Kohlenstoffanteil im Koksgas ist verringert.The method according to the invention and the device according to the invention result in a number of further advantages. The achievable high degree of solidification allows the use of previously unusable types of coal. In particular, preheated coal and with additives, in particular binders, mixed coal can be used. The new process opens up more scope to respond to changing charcoal properties. The use of the coking process impairing water as a binder can be reduced. Because of the high densification of the coal, which may be due to plastic deformation of the carbon grains on the densification in a densest possible ball packing, carbon arising during the coking by cracking processes remains largely in the coal cake and does not adhere to the inner wall of the coking furnace adversely. The carbon content in the coke gas is reduced.
In weiterer Ausgestaltung der Erfindung können die Presselemente eine, insbesondere vertikale, Wand der Form bilden.In a further embodiment of the invention, the pressing elements can form a, in particular vertical, wall of the mold.

Kohlekuchens nach der Erfindung, Fig. 2 einen Teil der Vorrichtung von Fig. 1 , und Fig. 3 ein zweites Ausführungsbeispiel für eine Vorrichtung nach der Erfindung. Auf einer massiven Basisplatte 1 der in Fig. 1 gezeigten Vorrichtung ist eine Form 2 für die Aufnahme einer Schüttung 3 aus gemahlener Kohle angeordnet. Über der kastenförmigen, nach oben offenen Form 2 sind Pressstempel 4 mit je einer Pressplatte 5 vorgesehen. In dem gezeigten Zustand der Vorrichtung liegen die Press- platten 5 gegen die Schüttung 3 an, wobei sie die freie Oberfläche der Schüttung nahezu vollständig abdecken.Coal cake according to the invention, Fig. 2 shows a part of the device of Fig. 1, and Fig. 3 shows a second embodiment of a device according to the invention. On a solid base plate 1 of the apparatus shown in Fig. 1, a mold 2 for receiving a bed 3 of ground coal is arranged. About the box-shaped, upwardly open mold 2 press punches 4 are each provided with a press plate 5. In the state of the device shown, the press plates 5 abut against the bed 3, covering almost completely the free surface of the bed.
In dem hier beschriebenen Ausführungsbeispiel sind die Presselemente 4 jeweils mit einer in Fig. 2 näher beschriebenen Hammereinrichtung 28 verbunden, deren Gehäuse 1 1 an einem horizontalen Balken 6 angebracht ist, welcher sich durch Hydraulikzylinder 7 vertikal verfahren lässt und über den eine durch Hydraulikzylinder 7 erzeugte Presskraft auf die Presselemente 4 übertragbar ist. Die Hydraulikzylinder 7 sind bei 8 mit einem horizontalen Schenkel 9 eines an der Basisplatte 1 angebrachten Spannrahmens 10 verbunden.In the embodiment described here, the pressing elements 4 are each connected to a hammer device 28 described in more detail in Fig. 2, the housing 1 1 is attached to a horizontal bar 6, which can be moved vertically by hydraulic cylinder 7 and on the one generated by hydraulic cylinder 7 Press force on the pressing elements 4 is transferable. The hydraulic cylinders 7 are connected at 8 with a horizontal leg 9 of an attached to the base plate 1 tenter 10.
Wie insbesondere aus Fig. 2 hervorgeht, ist in einem Buchsenteil 12 des Gehäuses 1 1 ein Schlagbolzen 13 geführt, dessen dem Gehäuse 1 1 abgewandtes Ende lose gegen einen mit der Pressplatte 5 verbundenen Ansatz 14 anliegt. In einen rotationssymmetrischen Innenraum 15 des Gehäuses 1 1 hinein steht vom Gehäuse 1 1 ein Ringvorsprung 16 vor, welcher einen mit dem Schlagbolzen 13 verbundenen Ringvorsprung 17 hintergreift, so dass über die Ringvorsprünge die Presskraft vom Gehäuse 1 1 auf den Schlagbolzen 13, der einen Teil des Presselements 4 bildet, und damit auf die Pressplatte 5 übertragbar ist.As is apparent in particular from FIG. 2, a firing pin 13 is guided in a socket part 12 of the housing 1 1, whose end facing away from the housing 1 1 is applied loosely against a projection 14 connected to the pressing plate 5. In a rotationally symmetrical interior 15 of the housing 1 1 in from the housing 1 1 is an annular projection 16 which engages behind a connected to the firing pin 13 annular projection 17, so that on the annular projections, the pressing force from the housing 1 1 on the firing pin 13, the part of the pressing element 4 forms, and thus on the press plate 5 is transferable.
In einem oberen Teil des Innenraums 15 ist ein Kopf 18 des Schlagbolzens 13 angeordnet, auf weichen ein zum Schlagbolzen 13 koaxialer Hammerbolzen 19 der Hammereinrichtung 28 aufschlagen kann. Der in einer Führung 20 gemäß Pfeil 21 hin und her bewegbare Hammerbolzen 19 steht mit einem nicht gezeigten hydraulischen Antriebszylinder in Verbindung.In an upper part of the inner space 15, a head 18 of the firing pin 13 is arranged, on which a soft to the firing pin 13 coaxial hammer bolt 19 of the hammer device 28 can strike. The in a guide 20 according to arrow 21 movable back and forth hammer pin 19 is connected to a hydraulic drive cylinder, not shown in connection.
Zur Herstellung eines Kohlekuchens wird gemahlene Einsatzkohle in die Form 2 geschüttet, wobei je nach Höhe des herzustellenden Kohleblocks die Einfüllung und Bearbeitung der Schüttung 3 lagenweise oder in einem einzigen Arbeitsgang erfolgen kann. Auf die freie Oberfläche der Schüttung 3 werden die Press- elemente 4 aufgesetzt und mit Hilfe der Hydraulikzylinder 7 wird eine Presskraft erzeugt, welche der Balken 6 auf alle Gehäuse 1 1 und die Gehäuse 1 1 über die Schlagbolzen 13 auf die Pressplatten 5 übertragen. Neben der kontinuierlichen Beaufschlagung durch die Presskraft erfolgt impulsweise eine Bearbeitung der Schüttung durch die Hαmmerbolzen 19, welche jeweils ihren Impuls im Rahmen eines elastischen Stoßes weitgehend auf die den Schlagbolzen 13 und die Pressplatten 5 umfassenden Presselemente 4 übertragen. Die Presselemente 4 geben den übernommenen Impuls im Rahmen eines weitgehend inelastischen Stoßes an die Schüttung 3 ab.To produce a coal cake ground feed coal is poured into the mold 2, wherein depending on the height of the produced coal block, the filling and processing of the bed 3 can be done in layers or in a single operation. On the free surface of the bed 3, the pressing elements 4 are placed and with the help of the hydraulic cylinder 7, a pressing force is generated which the beam 6 transmitted to all housing 1 1 and the housing 1 1 on the firing pin 13 on the press plates 5. In addition to the continuous loading by the pressing force takes place in pulses processing of the Batch by the Hαmmerbolzen 19, which each transmit their momentum in the context of an elastic shock largely on the firing pin 13 and the press plates 5 comprehensive pressing elements 4. The pressing elements 4 release the acquired pulse as part of a largely inelastic shock to the bed 3.
Durch die Kombination von Impulsbeaufschlagung und kontinuierlicher Pressung der Schüttung wird eine hohe Verdichtung erreicht, und es entsteht ein stabiler Kohlekuchenblock.Through the combination of impulse loading and continuous pressing of the bed a high compression is achieved, and it creates a stable coal cake block.
Es wird nun auf Fig. 3 Bezug genommen, wo gleiche oder gleichwirkende Teile mit derselben Bezugszahl wie in Rg. 1 und 2 bezeichnet sind, wobei der betreffenden Bezugszahl der Buchstabe a beigefügt ist.Reference is now made to Fig. 3, where the same or equivalent parts are designated by the same reference numerals as in Rg. 1 and 2, wherein the relevant reference number of the letter a is attached.
Das Ausführungsbeispiel von Fig. 3 unterscheidet sich von dem vorangehenden Ausführungsbeispiel dadurch, dass eine Impuls- und Pressbeaufschlagung einer Schüttung 3a nicht in vertikaler sondern horizontaler Richtung erfolgt. Eine vertikale Basisplatte 1 a hoher Masse und Pressplatten 5a bilden Seitenwände einer die Schüttung 3a aufnehmenden Form.The embodiment of Fig. 3 differs from the previous embodiment in that a pulse and Pressbeaufschlagung a bed 3a is not in the vertical but horizontal direction. A vertical base plate 1 a high mass and pressing plates 5 a form side walls of the bulk receiving a form 3a.
Wie bei dem vorangehenden Ausführungsbeispiel sind auf die Pressplatten 5a einwirkende Schlagbolzen 13a durch nicht gezeigte Hammerbolzen beaufschlagbar.As in the previous embodiment, striker pins 13a acting on the presser plates 5a can be acted on by hammer pins (not shown).
Stützkonstruktionen 22 und 23 sind jeweils im Boden verankert und an ihrer Oberseite durch einen Zuganker 24 miteinander verbunden.Support structures 22 and 23 are each anchored in the ground and connected at their top by a tie rod 24 together.
Die Einheit aus Presselementen 4a, Hammereinrichtungen 28a und Balken 6a, die durch einen weiteren vertikalen Träger 25 verstärkt ist, lässt sich über Rollen 26 auf einer Bodenplatte 27, welche auch den die Schüttung 3a aufnehmenden Formraum nach unten abschließt, bewegen.The unit of pressing elements 4a, hammers 28a and beams 6a, which is reinforced by a further vertical support 25, can be moved via rollers 26 on a bottom plate 27, which also closes down the mold space receiving the bed 3a.
In dem gezeigten Ausführungsbeispiel beträgt die horizontale Breite der Schüttung 3a in Pressrichtung etwa 0,5 m. Bei dieser Breite lässt sich eine homogene Verdich- tung über das gesamte Schüttungsvolumen erreichen. Die Herstellung des Kohleformblocks bedarf nur eines einzigen Schüttungsarbeitsgangs. In the embodiment shown, the horizontal width of the bed 3a in the pressing direction is about 0.5 m. With this width, a homogeneous compaction over the entire bulk volume can be achieved. The preparation of the coal forming block requires only a single batch operation.
