Die Erfindung betrifft einen Kühler für durch Vergasung von Kohle unter Druck erzeugte Gase nach dem Oberbegriff des Anspruches 1.The invention relates to a cooler for gases generated by gasification of coal under pressure according to the preamble of
Bei einem bekannten Kühler (EP-PS 48 326) sind einzelne Rohre des Einsatzes so abgekröpft, daß sie einen als Rohrwand ausgebildeten Hals bilden, der eine Gaszuführungsleitung darstellt. Im Bereich der Abkröpfung bilden die Rohre die Decke des Einsatzes. Die EP-PS 48 326 enthält keine Angaben darüber, wie die Rohre zu der Decke ausgebogen und angeordnet sind.In a known cooler (EP-PS 48 326) individual tubes of the insert are bent so that they form a neck formed as a tube wall, which is a gas supply line. In the area of the bend, the tubes form the ceiling of the insert. EP-PS 48 326 contains no information about how the pipes are bent and arranged to the ceiling.
Der Erfindung liegt die Aufgabe zugrunde, den gattungsgemäßen Kühler so zu gestalten, daß mit einfachen Mitteln die Decke des Einsatzes gebildet werden kann.The invention has for its object to design the generic cooler so that the ceiling of the insert can be formed with simple means.
Diese Aufgabe wird bei einem gattungsgemäßen Kühler erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruches 1 gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.This object is achieved according to the invention in a generic cooler by the characterizing features of
Die innerhalb der Sektoren parallel laufenden Rohre lassen sich durch zwischengelegte Stege bei gleichbleibender Stegbreite zu einer gasdichten Decke verbinden. Die zwischen den Sektoren entstehenden dreieckigen Räume werden durch die Gabelstücke, die jeweils zwei unter einem Winkel zusammenstoßende Rohre zusammenführen, gasdicht geschlossen. Durch die gleichbleibende Rohrteilung in der Decke können in vorteilhafter Ausgestaltung der Erfindung die Rohre eines weiteren, innenliegenden Einsatzes über T-Stücke in einfacher Weise in die Decke eingebunden werden.The pipes running parallel within the sectors can be connected to a gas-tight ceiling by means of interposed webs with the same web width. The triangular spaces that arise between the sectors are sealed gas-tight by the fork pieces, which each bring together two pipes that meet at an angle. Due to the constant pipe division in the ceiling, in an advantageous embodiment of the invention, the pipes of a further internal insert can be easily integrated into the ceiling via T-pieces.

Der Kühler besteht aus einem Druckgefäß 1 mit einem oberen Stutzen 2 und einem unteren Stutzen 3. Der obere Stutzen 2 ist mit dem Ausgang eines unter Druck betriebenen Reaktors verbunden, in dem durch Vergasung von Kohle ein Gas erzeugt wird, das in dem durchekühlt wird. Über den unteren Stutzen 3 wird der in dem Gas enthaltene Vergasungsrückstand abgeführt. Zum Schutz der Gehäusewand ist in dem unteren Teil des Druckgefäßes 1 ein Aschetrichter 4 angeordnet.The cooler consists of a
Innerhalb des Druckgefäßes 1 ist ein gekühlter Einsatz 5 abgeordnet, in dem weitere plattenförmige Heizflächen untergebracht sind. Aus Gründen der Übersichtlichkeit sind diese Heizflächen nicht dargestellt. Der Einsatz 5 ist aus Rohrtafeln zu einem regelmäßigen n-Eck zusammengesetzt. Die Rohrtafeln bestehen aus senkrecht angeordneten Rohren 6, die durch Stege 7 zu einer gasdichten Rohrwand miteinander verbunden sind. Die Rohre 6 sind von einem Kühlmittel von unten nach oben durchströmt, das über einen Sammler 8 am unteren Ende des Einsatzes 5 zugeführt und über einen Sammler 9 am oberen Ende abgeführt wird. Als Kühlmittel wird Wasser verwendet, das in den Rohren des Einsatzes 5 verdampft und das als Wasser-Dampf-Gemisch aus dem Sammler 9 abgeführt wird.A cooled
Der Einsatz 5 ist an dem unteren, im Querschnitt verengten Ende zum Druckgefäß 1 hin offen. An die Wand des Druckgefäßes 1 ist in einer Ebene oberhalb der Unterkante des Einsatzes 5 ein Gasabführungsstutzen 10 angeschlossen.The
Zur Anpassung an den Querschnitt des oberen Stutzens 2 sind die Rohre 6 des Einsatzes 5 am oberen Ende abgekröpft, so daß eine Decke 11 gebildet wird, die in einen Eintrittsabschnitt 12 übergeht. Der Eintrittsabschnitt 12 ist aus einem Teil der Rohre 6 des Einsatzes 5 aufgebaut, die über Stege zu einer gasdichten Rohrwand miteinander verbunden sind.In order to adapt to the cross section of the
Wie am besten aus der Fig. 3 zu erkennen ist, sind innerhalb der Decke 11 die Rohre 6 sektorweise parallel zueinander und zu der Mittelsenkrechten der jeweiligen Seite des n-Eckes des Einsatzes 5 verlegt. Die Rohre 6 sind durch Stege 7 zu einer gasdichten Rohrwand verschweißt. Die Stegbreite und die Rohrteilung von Einsatz 5 und Decke 11 stimmen überein. Durch die sektorweise parallele Anordnung der Rohre 6 entstehen zwischen den Sektoren dreieckige Zwischenräume. Die im Bereich dieser Zwischenräume unter einem Winkel aneinanderstoßenden Rohre 6 sind paarweise über ein geschmiedetes Gabelstück 13 miteinander verbunden. Das Gabelstück 13 weist am hinteren Ende zwei Rohranschlüsse für die Verbindung mit einem Rohrpaar auf und läuft zum vorderen geschlossenen Ende konisch zu. Die Gabelstücke 13 sind entlang einer zur Längsachse des Einsatzes 5 weisenden geraden Linie in der Weise angeordnet, daß jeweils ein Gabelstück 13 mit dem vorderen Ende zwischen den Rohranschlüssen des folgenden Gabelstückes 13 mit diesem verbunden ist. Die konisch verlaufenden Längskanten des Gabelstückes 13 folgen der Richtung der Rohrachsen in den benachbarten Sektoren der Decke 11. An jedes Gabelstück 13 ist rechtwinklig ein Rohrstutzen 14 angeformt. Die Rohrstutzen 14 der hintereinander liegenden Gabelstücke 13 sind an eine Rohrleitung 15 angeschlossen, die außerhalb des Eintrittsabschnittes 12 zu dem oberen Sammler 9 geführt sind.As can best be seen from FIG. 3, the
Die nicht über die Gabelstücke 13 miteinander verbundenen Rohre 6 sind jeweils über einen Rohrbogen 16 weitergeführt und bilden die Rohrwand des Eintrittsabschnittes 12. Die Rohrbögen 16 springen nach innen vor und bilden Konsolen, auf denen eine feuerfeste Ausmauerung 17 abgestützt ist, mit der der gekühlte Eintrittsabschnitt 12 ausgekleidet ist.The
Die beschriebene Ausbildung der Decke 11 gestattet in einfacher Weise die Anordnung eines weiteren, innenliegenden Einsatzes 18. Dieser weitere Einsatz 18 weist wie der äußere Einsatz 5 einen n-eckigen Querschnitt auf, wobei die Seiten der n-Ecke parallel verlaufen. Der Einsatz 18 ist aus einer gasdichten Rohrwand gebildet, deren Rohrteilung und Stegbreite mit der des Einsatzes 5 übereinstimmt. Die Rohre 6 der Decke 11 sind getrennt und nehmen jeweils den Fuß eines rohrförmigen T-Stückes 19 auf, der mit den so getrennten Rohrabschnitten verschweißt wird. Jedes Rohr des weiteren Einsatzes 18 ist mit dem nach unten weisenden Steg des T-Stückes 19 verbunden, so daß die Rohrwand des weiteren Einsatzes 18 in die Decke eingebunden ist.The described design of the
