"Verfahren und Anlage zur Teerverwertung bei der Druckvergasung, insbesondere von Steinkohle""Process and system for tar utilization in pressurized gasification, especially of hard coal "

Die Erfindung betrifft ein Verfahren zum Verwerten von Teer, der aus Gasen der Druckvergasung, insbesondere von Steinkohle, abgeschieden wird, bei dem der erhaltene Teer in die Druckvergasung des Brennstoffes zurückgeführt wird. Die Erfindung betrifft auch eine Anlage zur Durchführung dieses Verfahrens-The invention relates to a method for utilizing tar obtained from gases from pressurized gasification, in particular from hard coal, is deposited, in which the tar obtained is returned to the pressure gasification of the fuel. the The invention also relates to an installation for carrying out this Procedural

Bei einem bekannten Verfahren (DL-PS 74 071) werden abgeschiedene Kohlenwasserstoffe, insbesondere Teer, aufgeheizt und in die Reaktions- oder Umsetzungszone des Druckyergasers eingeführt. Dort werden sie durch Anlagerung von Wasserstoff gespalten. Das Verfahren hat den Vorteil, daß der in dem ProzeB der Druckvergasung anfallende Teer einbezogen wird. Hierbei wird Gas mit den aus dem Teer gewonnenen niedrigsiedenden Kohlenwasserstoffen angereichert. Es verläßt deshalb den Druckvergaser unter einem höheren Heizwert. Die Einführung des Teeres in den Druckvergaser bereitet allerdings erhebliche Schwierigkeiten. Unter anderemIn a known method (DL-PS 74 071) separated hydrocarbons, in particular tar, are heated and into the reaction or conversion zone of the pressure gaser introduced. There they are split by the addition of hydrogen. The method has the advantage that the tar accruing in the process of pressurized gasification included will. Here, gas is enriched with the low-boiling hydrocarbons obtained from the tar. It therefore leaves the pressure gasifier with a higher calorific value. The introduction of the tar into the pressure gasifier prepares however, considerable difficulties. Among other things

muß die im allgemeinen zähflüssige Teernasse mit Hilfe von Pumpen durch Leitungen in den Generator gedrückt werden.the generally viscous tar has to be pressed through pipes into the generator with the help of pumps will.

Ein anderes Problem beim Betrieb von Generatoren zur Druckvergasung entsteht durch den Staubgehalt des Generatorgases. Sein Staubgehalt ist umso größer, je höher der Anteil an Unterkorn von 0-2 mm in der Feinkohle ist, die dem Schacht des Generators aufgegeben wird. Andererseits fallen bis zu 70 % der Kohle bei den in der Steinkohlengewinnung und Aufbereitung üblichen Verfahren an. Deswegen muß die Feinkohle klassiert werden, bevor sie dem Schacht aufgegeben wird. Dieses Aufgabegut hat im allgemeinen eine Körnung von 2-30 mm. Das Unterkorn führt zu einem unerwünscht hohen Staubanteil im erzeugten Gas. Außerdem führt es zu schlechtem Zug in der im Schacht des Generators stehenden Säule des Brennstoffes ·Another problem with the operation of generators for pressurized gasification arises from the dust content of the generator gas. Its dust content is greater, the higher the proportion of undersized grains of 0-2 mm in the fine coal that is fed into the shaft of the generator. On the other hand, up to 70 % of the coal is produced in the usual methods of hard coal extraction and processing. Therefore, the fine coal must be classified before it is given to the shaft. This feed material generally has a grain size of 2-30 mm. The undersized grain leads to an undesirably high proportion of dust in the gas produced. In addition, it leads to bad draft in the column of fuel in the shaft of the generator

Der Erfindung liegt die Aufgabe zugrunde, die Rückführung des Teers in den Druckvergaser zu vereinfachen und das Unterkorn im Aufgabegut des Generators zu verringern.The invention is based on the object to simplify the return of the tar in the pressure gasifier and that To reduce undersized grain in the feed material of the generator.

Diese Aufgabe wird erfindungsgemäS dadurch gelöst, daß der Teer als Bindemittel bei einer Pelletierung feinkörniger Bestandteile des Brennstoffes zugesetzt und mit den Pellets in den Generator eingebracht wird.This object is achieved according to the invention in that the tar, as a binder, is finely grained when pelletized Components of the fuel added and with the pellets are introduced into the generator.

Hierdurch werden die bislang zur Zuführung des Teers in die Reaktionszone des Druckvergasers benötigten Einrichtungen überflüssig. Dennoch gelangt der Teer in die Reaktionszone des Generators, weil die Pellets sich wie die übrigen Teilchen des Brennstoffes verhalten und den Teer in die Reaktionszonen transportieren.This eliminates the facilities previously required for feeding the tar into the reaction zone of the pressurized gasifier superfluous. Nevertheless, the tar gets into the reaction zone of the generator because the pellets are like the others Behave particles of the fuel and transport the tar into the reaction zones.

Die Pelletierung erfaßt außerdem bevorzugt das Unterkorn von 0-2mm. Die Pellets selbst haben jedoch die für die Druckvergasung benötigte Korngröße, vorzugsweise ca. 20 mm. Sie reduzieren deshalb den Staubaustrag im Generatorgas entsprechend. Die Verringerung des Staubaustrages ermöglicht es, die dem Generator nächgeschaltete Gasreinigungsvorrichtung kleiner auszuführen. Auch das in der Gasreinigungsanlage anfallende Gemisch, das aus Teer und Staub besteht, weist ein günstigeres Teer-Staub-Verhältnis auf. Hierdurch werden die Transporteigenschaften des zur Pelletierung dienenden Teers verbessert. Der Staub-Austrag beim Einschleusen des Brennstoffes in den Generator wird ebenfalls vermindert.The pelleting also preferably covers the undersize of 0-2mm. The pellets themselves, however, have those for that Pressurized gasification required grain size, preferably approx. 20 mm. They therefore reduce the dust discharge in the generator gas corresponding. The reduction in the amount of dust discharged makes it possible to use the gas cleaning device connected downstream of the generator run smaller. Also the mixture of tar and If there is dust, it has a more favorable tar-dust ratio. As a result, the transport properties of the to Pelletizing tar improved. The dust is discharged when the fuel is introduced into the generator also decreased.

Die erfindungsgemäße Anlage zur Durchführung des beschriebenen Verfahrens weist einen Generator, eine Beschickungseinrichtung zur Zufuhr körnigen Brennstoffs und einen Teerabscheider auf. Erfindungsgemäß hat diese Anlage eine Granuliereinrichtung, die ihrerseits für die Zugabe eines Bindemittels mit einem Teerabscheider durch eine Teer führende Leitung verbunden ist. Diese Granuliereinrichtung enthält auch die Pelletierung, die wenigstens einen Pelletierteller aufweisen kann. Der GranuliereinrichtungThe system according to the invention for carrying out the method described has a generator, a charging device for supplying granular fuel and a tar separator. According to the invention, this system has a Granulating device, in turn, for the addition of a binder with a tar separator through a tar leading line is connected. This granulating device also contains the pelleting, the at least one May have pelletizing plates. The granulating device

Ein Druckgenerator 1 erhält körnigen Brennstoff, nämlich Kohle bei 2 und als Vergasungsmittel Dampf bei 3 und erzeugt durch Reaktion des Brennstoffes Gas, das den Generator 1 bei 4 verläßt. Die anfallende Asche wird bei 5 abgezogen.A pressure generator 1 receives granular fuel, namely coal at 2 and steam as a gasifying agent at 3 and generated by reaction of the fuel gas which leaves the generator 1 at 4. The resulting ash will deducted at 5.

Der für den Betrieb des Druckvergasers 1 erforderliche Brennstoff besteht aus Feinkohle mit einer Kornspanne von 0-30 mm. Diese wird mit einem Fördermittel 6 einem Spannwellensieb 7 aufgegeben, das Korngrößen von 0-3 mm, von den grobkörnigen Bestandtelbn von 3-30 mm abtrennt. Der Siebüberlauf 3-30 mm wird über einen Transportweg 8 dem Generator 1 unmittelbar aufgegeben. Der Siebdurchlauf 0-3 nun gelangt auf einen Pelletierteller 9. Auf diesen werden Pellets aus der Kohle und dem als Bindemittel dienenden Teer hergestellt. Der Teer stammt aus einem dem Generator 1 nachgeschälteten Teerabscheider, der nicht dargestellt ist. Der Teer fließt durch eine Leitung 10 und gelangt auf den Pelletierteller 9. Die grünen Pellets werden über einen Transportweg 11 zum Kohledruckvergaser 1 gebracht und als grüne Pellets in den Generator 1 eingeführt.The fuel required to operate the pressure gasifier 1 consists of fine coal with a grain range from 0-30 mm. This is fed with a conveyor 6 to a flip-flop screen 7, the grain sizes of 0-3 mm, from the coarse-grained constituents of 3-30 mm. The screen overflow 3-30 mm is fed directly to the generator 1 via a transport path 8. The sieve pass 0-3 now arrives at a pelletizing plate 9. On this pellets are made from the coal and the binding agent made serving tar. The tar comes from a tar separator downstream of the generator 1, which is not shown. The tar flows through a line 10 and reaches the pelletizing plate 9. The green pellets are brought to the coal pressure gasifier 1 via a transport path 11 and as green pellets in the generator 1 introduced.
