Description
Der Erfindung betrifft ein System zur Druckförderung von Staub-Gas-Suspensionen bei Drücken bis 10 MPa mit den Merkmalen des Oberbegriffs des Anspruchs 1.The invention relates to a system for pressure conveying of dust-gas suspensions at pressures up to 10 MPa with the features of the preamble of
Die Erfindung bezieht sich auf ein Staubeintragsystem, das in der Lage ist, Stäube von Umgebungsdruck auf ein sehr hohes Druckniveau, von beispielsweise 10 MPa, mit Inertgas zu bespannen und förderbar zu machen.The invention relates to a Staubeintragsystem, which is able to cover dusts of ambient pressure to a very high pressure level, for example, 10 MPa, with inert gas to make and recoverable.
In vielen technischen Prozessen ist es erforderlich, Stäube auf ein sehr hohes Druckniveau anzuheben. Genannt sei beispielsweise die Kohlenstaubvergasung mit Vergasungsdrücken bei pneumatischer Staubförderung, die bisher auf ca. 4 MPa (40 bar) beschränkt sind. Nach dem Stand der Technik benutzt man zur Überwindung dieser Drücke bei der Staubdruckvergasung ein einstufiges Schleusensystem, wie es in „NOELL-KONVERSIONSVERFAHREN ZUR VERWERTUNG UND ENTSORGUNG VON ABFÄLLEN”, EF-Verlag für Energie- und Umwelttechnik GmbH, 1996, Seite 34 beschrieben ist. Dabei wird der Brennstaub aus einem unter Umgebungsdruck stehenden Vorratsbunker Schleusen zugeführt, die anschließend durch Zuführung eines kondensatfreien Inertgases auf den erforderlichen Umgebungsdruck bespannt werden. Durch Schwerkraftförderung gelangt nunmehr der unter Druck stehende Brennstaub in ein gleichen Druck aufweisendes Dosiergefäß, das unter den Druckschleusen angeordnet ist. Im Unterteil des Dosiergefäßes wird durch Zuführung eines gleichfalls inerten Fluidisierungsgases eine sehr dichte Wirbelschicht erzeugt, in die eine oder mehrer Staubförderleitungen eintauchen. Durch Anlegen einer Druckdifferenz zwischen dem Dosiersystem und dem Empfänger des Brennstaubes, z. B. einem Vergasungsreaktor, fließt der Brennstaub diesem als dichte Staub-Gassuspension zu. Diese Förder- und Dosiertechnologie hat sich in der Praxis bewährt, besitzt aber den Nachteil, dass der Druck auf ca. 40 bar begrenzt ist, um den Verbrauch an Bespannungsgas zu begrenzen. Weiterhin bedeuten die großen Druckunterschiede in den Schleusen zwischen Umgebungsdruck bei Befüllung der Schleusen und der Bespannung auf den gewünschten Betriebsdruck eine hohe Belastung der staubführenden Armaturen, was erheblichen Verschleiß zur Folge hat. Ist ein Vergasungsprozess bei höheren Drücken von beispielsweise 40 bis 100 bar durchzuführen, so ging man zum Einsatz von Kohlenstaub-Wasser-Suspensionen, sogenannten Slurries über, wie es beispielsweise in Dürrfeld u. a., „Förderung und Dosierung von Kohle/Wassersuspensionen”, Chem.-Ing.-Technik 56 (1984) 6, S. 496–97 beschrieben ist. Diese Technologie besitzt den Nachteil, dass erhebliche Wassermengen dem Vergasungsprozess zugeführt werden mit Wirkungsgradverlusten bis zu 10%.In many technical processes, it is necessary to raise dusts to a very high pressure level. For example, coal dust gasification with gasification pressures in the case of pneumatic dust extraction, which has hitherto been limited to about 4 MPa (40 bar), may be mentioned. According to the prior art is used to overcome these pressures in the Staubdruckvergasung a single-stage lock system, as described in "NOELL CONVERSIONS PROCESSES FOR RECYCLING AND DISPOSAL OF WASTE", EF-Verlag for energy and environmental technology GmbH, 1996, page 34. In this case, the fuel dust is supplied from a storage bunker under ambient pressure locks, which are then covered by supplying a condensate-free inert gas to the required ambient pressure. By gravity now reaches the pressurized fuel dust in a same pressure exhibiting Dosiergefäß, which is located under the pressure locks. In the lower part of the metering vessel, a very dense fluidized bed is produced by supplying a likewise inert fluidizing gas into which one or more dust conveying lines dip. By applying a pressure difference between the metering system and the receiver of the fuel dust, z. As a gasification reactor, the fuel dust flows to this as a dense dust gas suspension. This delivery and metering technology has proven itself in practice, but has the disadvantage that the pressure is limited to about 40 bar to limit the consumption of stringing gas. Furthermore, the large pressure differences in the locks between ambient pressure when filling the locks and the covering to the desired operating pressure mean high loads on the dust-carrying fittings, which results in considerable wear. If a gasification process is carried out at higher pressures of, for example, 40 to 100 bar, then the use of pulverized coal-water suspensions, so-called slurries, was initiated, as described, for example, in Dürrfeld u. a., "Promotion and dosage of coal / water suspensions", Chem.-Ing. Technique 56 (1984) 6, p 496-97 is described. This technology has the disadvantage that significant amounts of water are fed to the gasification process with efficiency losses of up to 10%.
Der Erfindung liegt die Aufgabe zugrunde, ein Staubeintragsystem so zu gestalten, dass trotz hoher Drücke von 40 bis 100 bar sowohl die benötigte Menge des Bespannungsgases als auch die Belastung der Armaturen begrenzt wird.The invention has for its object to make a Staubeintragsystem so that, despite high pressures of 40 to 100 bar, both the required amount of the stringing gas and the load on the valves is limited.
Die Aufgabe wird durch Anwendung eines zweistufigen Schleusensystems gelöst, in dem die erste Stufe aus einer Staubpumpe und die zweite Stufe aus einer Druckschleuse besteht, wie es Anspruch 1 wiedergibt.The object is achieved by using a two-stage lock system in which the first stage consists of a dust pump and the second stage of a pressure lock, as it reproduces
Durch diese Kombination kann der durch eine Staubpumpe zu überwindende Druckunterschied deutlich reduziert werden, wodurch die Belastung der Armaturen vermindert ist.This combination can be significantly reduced by a dust pump to overcome pressure difference, whereby the load on the valves is reduced.
Vorteilhafte Lösungen der Erfindung sind in den Unteransprüchen angegeben.Advantageous solutions of the invention are specified in the subclaims.
In einer Weiterbildung der Erfindung gelangt das durch den Staubeintrag in die Staubschleusen verdrängte Gas über die kombinierte Ent- und Bespannungsleitung in die gerade mit Staub gefüllten, aber zunächst noch drucklosen Kammern der Staubpumpe. Dadurch wird der Bedarf an Bespannungsgas, welches über die kombinierte Ent- und Bespannungsleitung der Staubpumpe zuzuführen ist, reduziert.In one embodiment of the invention, the displaced by the dust entry into the dust locks gas passes through the combined drain and Bespannungsleitung in the just filled with dust, but initially still unpressurized chambers of the dust pump. This reduces the need for stringing gas which is to be supplied to the dust pump via the combined removal and tensioning line.
Die Erfindung wird im Folgenden als Ausführungsbeispiel anhand einer Figur in einem zum Verständnis erforderlichen Umfang erläutert. Dabei zeigt:The invention will be explained below as an exemplary embodiment with reference to a figure in a scope necessary for understanding. Showing:

Brennstoffe können zu Staub fein aufgemahlene Kohlen unterschiedlichen Inkohlungsgrades, Petrolkokse, Rest- und Abfallstoffe oder Biomassen sein, wie sie bei der Staubdruckvergasung mit freiem Sauerstoff enthaltenden Vergasungsmitteln zum Einsatz kommen.The pneumatic dust delivery system according to the invention is generally suitable for the promotion of dust-gas suspension. The dust delivery system is specifically designed to deliver fuel inert gas suspensions, such as those supplied to a gasification reactor. Fuels may be finely ground coal of varying degrees of coalification, petroleum cokes, residuals and wastes, or biomass, such as those used in dust gasification with free oxygen-containing gasifiers.
