Description

Vorrichtung zum Schwelen von Kohlen Gegenstand der Erfindung ist eine Vorrichtung zum Schwelen von Kohlen, bestehend aus zwei in den Schwelraum führenden, gegenläufig arbeitenden Schneckenfördertrommeln, die gleichachsig ineinander gelagert sind und von denen die eine die Zufuhr der Kahle in den Schwelraum und die andere das Abführen des Schwelkokses aus dem Schwelraum bewirkt. Das mit dieser Vorrichtung erstrebte Ziel besteht darin, die fühlbare Wärme dies festen Schwelerzeugnisses, durch unmittelbaren Wärmeaustausch zur Vorwä,rmung des zu schwelenden Gutes auszunutzen, um den Wärmehaushalt des Schwelverfahrens günstiger zu gestalten. Bei Verwendung der erfindungsgemäßen Vorrichtung wandert die Wärme von dem einen festen Stoff, dem Schwelkoks, durch die die beiden Schneckenfördertrommeln trennende Heizwand hindurch in den anderen festen Stoff, die Kohle.Apparatus for smoldering coals The invention is a Device for smoldering coals, consisting of two leading into the smoldering room, counter-rotating screw conveyor drums, which are stored in one another on the same axis and of which one is the supply of the baldness into the smoldering room and the other brings about the removal of the smoldering coke from the smoldering room. That with this device The aim is to absorb the sensible warmth of this solid smoldering product, to use through direct heat exchange for preheating of the goods to be smoldered, to make the heat balance of the smoldering process more favorable. Using the device according to the invention migrates the heat from the one solid substance, the smoldering coke, through the heating wall separating the two screw conveyor drums through into the other solid matter, the coal.

Es ist bereits bekannt, beim Schwelen die fühlbare Wärme der Schwelerzeugnisse durch mittelbaren oder unmittelbaren Wärmeaustausch zum Aufheizen des zu schwelenden Gutes heranzuziehen. Die hierzu vorgeschlagenen Einrichtungen haben jedoch denNachteil, daß sie sehr verwickelt sind. Die Bewegung der Einsatzkohle und des Schwelkokses unter Einschluß der Destillatiouserzeugnissp im Gegenstrom hat unter Benutzung der angemeldeten Vorrichtung gegenüber den als bekannt nachgewiesenen Einrichtungen überdies den Vorzug, daß der Abbrand, der bei kreisenden Gasen immer sehr hoch ist, völlig unterbunden wird. Vermieden wird auch die bisher stets bestehende Explosionsgefahr.It is already known that when smoldering, the tangible warmth of smoldering products by direct or indirect heat exchange to heat the smoldering To draw on good things. However, the facilities proposed for this purpose have the disadvantage that they are very involved. The movement of the feed coal and the low-temperature coke including the distillate products in countercurrent using the registered device against the facilities proven to be known moreover the advantage that the burn-up, which is always very high with circulating gases, is completely prevented. The danger of explosion that has always existed up to now is also avoided.

In der Zeichnung ist ein Ausführungsbeispiel einer derartigen Vorrichtung dargestellt. Durch die Schnecke i wird die in den Bunker aufgegebene Schwelkohle zum Schwelraum 3 gebracht, der durch Abgase von Brennstellen außerhalb des Ofens, die bei q. zur Außenwand der Schwelkammer gelangen, beheizt wird. Diese Abgase umkreisen die Schwelkammer 3, indem sie entlang der Spiralbleche 5 strömen, und treten durch den Stutzen 6 aus.' Die in der Schwelkammer 3 sich bildenden Schwelgase verlassen die Schwelkammer durch den Stutzen 7. Dort kann zur Rückgewinnung der in den Schwelgasen vorhandenen Wärme beispielsweise .ein 1Zekuperator zur Luftvorwärmung für die Beheizung eingebaut werden. Der in der Schwelkammer 3 entstehende Schwelkoks wird von der Schnecke 8 erfaßt und im Ge,genstro-m zur eintretenden Kohle nach der Schwelkoksaustrittsöffnung g befördert, um die im Schwelkoks enthaltene fühlbare Wärme an die durch die Schnecke i eintretende Kohle größtenteils abzugeben. Die ganze Einrichtung wird durch Schlackenwolle io o. dgl. isoliert, um die Wärmeverluste beim Schwelvorgang möglichst zu vermeiden.In the drawing is an embodiment of such a device shown. The low-carbon coal fed into the bunker is fed into the bunker by the screw i brought to the smoldering room 3, which is caused by exhaust gases from burning points outside the furnace, the at q. get to the outer wall of the smoldering chamber, is heated. Orbit these exhaust gases the smoldering chamber 3 by flowing along the spiral plates 5 and pass through the nozzle 6. ' The carbonization gases formed in the carbonization chamber 3 leave the smoldering chamber through the nozzle 7. There can be used to recover the smoldering gases Existing heat, for example, a 1Zekuperator to preheat the air for heating to be built in. The smoldering coke produced in the smoldering chamber 3 is used by the The screw 8 is detected and in the Ge, genstro-m to the coal entering after the smoldering coke outlet opening g conveyed to the sensible heat contained in the low-temperature coke to the through the screw i to surrender most of the coal entering. The whole facility is made of slag wool OK or the like. Insulated in order to avoid heat losses during the smoldering process as much as possible.
