Description
Stetig betriebener Spülgasschwelofen Das Patent 698 725 betrifft Minen senkrechten, stetig betriebenen Spülgasschwelofen von langgestreckt rechteckigem Querschnitt mit Gleichstromquerspülung und einseitiger Außenbeheizung durch in der einen Kammerlängswand angeordnete Heizzüge und damit verbundene Rekuperatoren, zwischen denen die Spülgaszuführungskanäle hindurchgehen.Continuously operated purge gas furnace. Patent 698,725 relates to mines vertical, continuously operated purge gas furnace from elongated rectangular Cross-section with direct current cross purging and one-sided external heating through in the a longitudinal chamber wall arranged heating flues and associated recuperators, between which the purge gas supply channels pass through.
Bei einer solchen einseitigen Beheizungsweise besteht ein gewisses Temperaturgefäll quer durch die Ofenkammer. Auch die Temperatur des Spülgas-Schivelgas-Gemisches nimmt während seines Weges von der Heizwandseite durch das Schwelgut und durch die nichtbieheizte Kammerwand ab.With such a one-sided heating method there is a certain Temperature gradient across the furnace chamber. Also the temperature of the purge gas / Schivel gas mixture takes during its way from the heating wall side through the Schwelgut and through the non-bend heated chamber wall.
Nach der Erfindung werden in dieser nichtbeheizten Kammerl;ängscvand Heizvorrichtungen angebracht. Durch diese zusätzliche Beheizung wird vor allem die Gefahr von Teerniederschlägen aus den sich abkühlenden Schwelgasen sowohl in den Gasdurchlässen der Kammerwand wie auch in dem hinter der Wand liegenden Gassammelraum vermieden. Die Heizvorrichtungen können dabei etwa als einfach oder doppelt geführte Kanäle zwischen den Schwelgasaustritten hindurchgeführt sein. Die Temperatur in der nach der Erfindung beheizten Kammerwand wird zweckmäßig .etwas Über Schweltemperatur gehalten, doch so, daß keine wesentliche Wärmeabgabe an das Schwelgut erfolgt.According to the invention, in this unheated chamber; Heating devices attached. This additional heating is mainly the Risk of tar deposits from the cooling smoldering gases both in the Gas passages in the chamber wall as well as in the gas collecting space behind the wall avoided. The heating devices can be run as single or double Channels be passed between the carbonization gas outlets. The temperature in the chamber wall heated according to the invention is expediently slightly above the smoldering temperature held, but in such a way that no significant heat is given off to the Schwelgut.
Es ist bereits bei einem Verfahren zur Behandlung von Koksofengasen mit aktivem Wasserstoff bekannt, die aus der Schmalseite eines zweiseitg außenbeheizten Kaminerofens zii einer Reaktionskammer abgeführten Gase durch wärmeübertragende Vorrichtungen zu kühlen oder zu erwärmen, um sie auf die zur Umsetzung mit dem Wasserstoff geeignete Temperatur zu bringen.It is already in a process for treating coke oven gases known with active hydrogen, which comes from the narrow side of a two-sided externally heated Chimney furnace zii a reaction chamber discharged gases by heat transferring Devices to cool or to heat in order to react them with the hydrogen bring suitable temperature.
Die Zeichnungen zeigen den neuen Ofen in beispielsweiser Ausführungsform. Es ist Abb. i ein senkrechter Schnitt durch den Ofen nach I-I der Abb.2 in Richtung des Spülgasweges, Abb.2 ein Querschnitt durch den Ofen nach II-11 der Abb. i.The drawings show the new furnace in an exemplary embodiment. It is Fig. I a vertical section through the furnace according to I-I of Fig.2 in the direction of the purge gas path, Fig.2 a cross section through the furnace according to II-11 of Fig. i.
i ist die Gaszuleitung für das gegebenenfalls vom Gas der Hauptleitung 12 verschiedene Heizgas, 2 sind die Brenner, 3 die zwischen den Schwelgasaustritten 5 durchgeführten Heizkanäle und .l ,isst der Abgasabzug. Die aus der Hauptleitung 6 kommenden Spülgase werden in den zwischen den Heizzugwänden verlaufenden Gasführungen 8 hoch erhitzt, durchstreichen das Gut in der Ofenkammer 9 und ziehen zusammen mit den Schwelgasen durch die Gasdurchlässe 5 in der gegenüberliegenden beheizten Kammerwand, werden dabei auf Temperaturen von etwa 65o° gebracht und gelangen über den Gassammelraum io in die Vorlage 11. i is the gas supply line for the heating gas, which may be different from the gas in the main line 12, 2 are the burners, 3 are the heating channels running between the carbonization gas outlets 5 and .l, is the exhaust gas vent. The purging gases coming from the main line 6 are heated up in the gas ducts 8 running between the heating duct walls, pass through the material in the furnace chamber 9 and, together with the carbonization gases, pull through the gas passages 5 in the opposite heated chamber wall, increasing to temperatures of around 65o ° brought and arrive via the gas collecting space io in the template 11.
