- Such a device designed as a radiation cooler is known from DE-OS 32 08 421 and is used for cooling the gases leaving a gasification reactor.
- the flat tube walls ensure intensive cooling of the gases.
- the radiation cooler is followed by a separate convection cooler with bundle heating surfaces.
- the invention has for its object to design the heating surfaces of the generic device so that a compact cooling device is created.
- the tube bundle serving as a convection heating surface By arranging the tube bundle serving as a convection heating surface within the radiation cooler, the gas can be cooled in a short way.
- the direct continuation of a flat tube wall in the tube bundle enables a compact design of the cooling device.
- the cooler shown is used to cool hot, pressurized and dust-laden gases, especially those that are generated in a gasification reactor.
- the cooler consists essentially of two components, namely a standing pressure vessel 1, which has the task of absorbing the pressure of the gas, for example from 20 to 25 bar, and of the internals which act as heat exchangers.
- the internals consist of an insert 2, flat tube walls 3 (bulkhead walls), a first tube bundle 4 and, if appropriate, a second tube bundle 5 or further tube bundles.
- the pressure vessel 1 consists of several cylindrical segment rings welded together. It is closed by an upper and a lower cover 6, 7.
- the upper cover 6 is provided with a gas inlet connection 8 and the lower cover with a gas outlet connection 9.
- a screwable flange connection 10 is inserted in the upper part of the pressure vessel 1 in order to ensure easy opening of the pressure vessel 1.
- the pressure vessel 1 can be parked in a scaffold with the help of claws.
- the insert 2 is arranged at a distance from the inner wall of the pressure vessel 1 and is connected to the gas inlet connection 8 in such a way that the gas to be cooled which flows in flows through the insert 2 in the longitudinal direction.
- the outlet end of the insert 2 is open, so that pressure equalization can take place between the interior of the insert 2 and the annular space between the insert 2 and the pressure vessel 1.
- the insert 2 is formed from gas-tight, welded, cooled pipes which are connected to an inlet header 11 located in the lower part and to an outlet header 12 located in the upper part.

- the tubes of the tube bundle 4 can also be surrounded by a welded-on sleeve.
- the tubes 13 of the tube walls 3 remaining on the wall plane on both sides of the middle tube wall 3 thus serve as support tubes, while the tubes 14 of these tube walls and the tubes 20 of the other tube walls are guided as loose tubes.
- a second tube bundle 5 or further tube bundles can be provided within the insert 2.
- the second tube bundle 5 can be connected as a superheater, feed water preheater or as an additional evaporator.

Der dargestellte Kühler dient zur Abkühlung von heißen, unter Druck stehenden und mit Staub beladenen Gasen insbesondere von solchen, die in einem Vergasungsreaktor erzeugt sind. Der Kühler besteht im wesentlichen aus zwei Bauteilen, nämlich einem stehenden Druckbehälter 1, der die Aufgabe hat, den Druck des Gases von beispielsweise 20 bis 25 bar aufzunehmen und aus den Einbauten, die als Wärmeüberträger fungieren. Die Einbauten setzen sich aus einem Einsatz 2, ebenen Rohrwänden 3 (Schottenwände), einem ersten Rohrbündel 4 und gegebenenfalls einen zweiten Rohrbündel 5 oder weiteren Rohrbündeln zusammen.The cooler shown is used to cool hot, pressurized and dust-laden gases, especially those that are generated in a gasification reactor. The cooler consists essentially of two components, namely a standing
Der Druckbehälter 1 besteht aus mehreren zylindrischen, miteinander verschweißten Segmentringen. Er ist durch einen oberen und einen unteren Deckel 6, 7 verschlossen. Der obere Deckel 6 ist mit einem Gaseintrittsstutzen 8 und der untere Deckel mit einem Gasaustrittsstutzen 9 versehen. Im oberen Teil des Druckbehälters 1 ist eine schraubbare Flanschverbindung 10 eingefügt, um ein einfaches Öffnen des Druckbehälters 1 zu gewährleisten. Der Druckbehälter 1 kann mit Hilfe von Pratzen in einem Gerüst abgestellt werden.The
Der Einsatz 2 ist mit Abstand von der Innenwand der Druckbehälters 1 angeordnet und so mit dem Gaseintrittsstutzen 8 verbunden, daß das eintretende, zu kühlende Gas den Einsatz 2 in Längsrichtung durchströmt. Das Austrittsende des Einsatzes 2 ist offen, so daß ein Druckausgleich zwischen den Innenraum des Einsatzes 2 und dem Ringraum zwischen dem Einsatz 2 und dem Druckbehälter 1 stattfinden kann.The
Der Einsatz 2 ist aus gasdicht miteinander verschweißten, gekühlten Rohren gebildet, die an einen im unteren Teil liegenden Eintrittssammler 11 und an einen im oberen Teil liegenden Austrittssammler 12 angeschlossen sind. Die Rohre des Einsatzes 2 sind von unten nach oben durchströmt und als verdampfer geschaltet.The
Die ebenen Rohrwände 3 sind innerhalb des Einsatzes 2 angeordnet und verlaufen in Längsrichtung des Druckbehälters 1 und parallel zueinander. Die Rohre 13, 14 der Rohrwände 3 sind über Flacheisen miteinander verbunden und jeweils an einen Eintrittssammler 16 und einen Austrittssammler 17 angeschlossen. Die Zuleitungen zu den Eintrittssammlern 11, 16 der Rohrwände 3 und des Einsatzes 2 sind durch den Ringraum zwischen dem Einsatz 2 und dem Druckbehälter 1 hindurchgeführt. Die Rohrwände 3 sind ebenso wie der Einsatz 2 als Verdampfer geschaltet und von unten nach oben durchströmt.The
Die Rohre mindestens einer der Rohrwände 3, vorzugsweise der mittleren Rohrwand sind zu dem ersten Rohrbündel 4 ausgebogen, das sich in mehreren Windungen über den Querschnitt des Einsatzes 2 erstreckt. Aus Gründen der Übersichtlichkeit ist in den Figuren 1 und 2 ein einflutiges Rohrbündel dargestellt. Es ist aber ebenso ein mehrflutiges Rohrbündel möglich. Das erste Rohrbündel 4 ist als Verdampfer geschaltet.The tubes of at least one of the
In dem Bereich der übrigen, nicht ausgebogenen Rohrwände 3 ist von jeweils drei benachbarten Rohren ein Rohr 14 aus der Ebene der Rohrwand 3 herausgebogen (Fig. 3). Auf diese Weise sind Gassen 18 innerhalb der Rohrwände 3 gebildet, durch die die Rohre des Rohrbündels 4 hindurchgeführt sind. In den der mittleren Rohrwand unmittelbar benachbarten Rohrwänden 3 sind die Rohre 13 beiderseits der Gassen 18 durch einen Steg 19 miteinander verbunden. Durch diesen Steg 19 werden die Rohre des Rohrbündels 4 hindurchgeführt und damit getragen. Im Bereich des Durchtrittes durch den Steg 19 können die Rohre des Rohrbündels 4 auch von einer aufgeschweißten Hülse umgeben sein. Die in der Wandebene verbleibenden Rohre 13 der Rohrwände 3 beiderseits der mittleren Rohrwand 3 dienen somit als Tragrohre, während die Rohre 14 dieser Rohrwände und die Rohre 20 der übrigen Rohrwände als lose Rohre geführt werden.In the area of the remaining, not
Innerhalb des Einsatzes 2 kann - wie in Fig. 2 dargestellt ist - ein zweites Rohrbündel 5 oder weitere Rohrbündel vorgesehen werden. Das zweite Rohrbündel 5 kann als Überhitzer, Speisewasservorwärmer oder als zusätzlicher Verdampfer geschaltet sein. Das zweite Rohrbündel 5 ist in gleicher Weise wie das erste Rohrbündel 4 durch die Rohrwände 3 hindurchgeführt und von diesen getragen. Das zweite Rohrbündel 5 ist an einen Eintrittssammler 21 und einen Austrittssammler 22 angeschlossen. Im Bereich der Sammler 21, 22 sind die Rohre der mittleren Rohrwand 3 wechselweise nach rechts und links ausgebogen und dienen der Halterung der Sammler 21, 22.As shown in FIG. 2, a
Der in Fig. 3 dargestellte Kühler weist einen an den unteren Deckel 7 angeschlossenen Gaseintrittsstutzen 8 und einen an den oberen Deckel 6 angeschlossenen Gasaustrittsstutzen 9 auf. Dabei ist das Rohrbündel 4 in den oberen Teil des Einsatzes 2 verlegt worden. Im übrigen stimmt dieser Kühler mit dem Kühler gemäß Fig. 1 überein. Bei einem solchen Kühler können die von den Rohrwänden 3 entfernten Verkrustungen in einfacherer Weise aus dem Kühler entfernt werden.The cooler shown in FIG. 3 has a gas inlet connection 8 connected to the
