Abstract

In a wash tower which cleans and cools hot gases the liq. sump, from which the wash liq. is recirculated to the tower, contains heat exchange elements from the transfer medium. For use in high pressure coal gasification processes using washing and gas cooling towers with oil circulation systems. Provides a simpler method of heat recovery than the use of separate heat exchangers in the hot gas stream.

und Gebrauchsmuster-Hilf sanme idung ~Vorrichtung zur Gaskühlung, Gaswaschung für vorzugsweise Gase innerhalb des Kohledruckvergasungsprozesses mit gleichzeitiger Dampfaufheizung bzw.and utility model assistance ~ device for gas cooling, Gas scrubbing for preferably gases within the coal pressure gasification process simultaneous steam heating or

Dampferzeugung bzw. Wärmeabgabe an ein Trägermedium' Bei der Kohledruckvergasung müssen die unter Druck stehenden heißen Gase zweckdienlich luftfrei gereinigt werden. Steam generation or heat dissipation to a carrier medium 'In the case of coal pressure gasification the pressurized hot gases must be cleaned air-free appropriately.

Um dieser Aufgabenstellung gerecht zu werden, wird eine Vorrichtung entsprechend beiliegender Zeichnung verwendet.In order to do justice to this task, a device used according to the accompanying drawing.

In der beiliegenden Zeichnung ist dargestellt: mit 1: der Rohgaseintritt, mit 2: der Reingasaustritt, mit 3: der Sprühturm, der zur Abkühlung des Rohgases von z.B. 5000 auf 20000 Anwendung findet, mit den erforderlichen Sprühdüseneinrichtungen, der auch gleichzeitig als Roligaswaschturm ausgebildet ist, mit 4: ist der Trennbereich zwischen Gaswaschung und das zur Waschung verwendete flüssige Waschmittel, z.B. öl, Stanzhöhe markiert, mit 5: sind die Wärmeaustauschflächen dargestellt, die im Waschmittelbunkerbereich verankert sind, mit 6: ist der Eingang eines aufzuheizenden Mediums, z.B. Dampfeinspeisung zur Aufheizung in den Wärmetauschflächen, dargestellt, mit 7: der Ausgang aus den Wärmetauschfläcben, mit 8: die Flüssigkeitspumpe zur Bedienung der Sprüh- und Wascheinrichtung, mit 9: die Abgabe aus dem Sumpf des Spru~h-, Waschturm- und Wärmeaustauschers, z.BO zur Reinigung der mit Teer und anderen Schadstoffen angereicherten vorgegebenen Waschfüllmenge.The attached drawing shows: with 1: the raw gas inlet, with 2: the clean gas outlet, with 3: the spray tower, which is used to cool the raw gas from e.g. 5000 to 20,000 is used, with the necessary spray nozzle devices, which is also designed as a Roligas washing tower, with 4: is the separation area between gas scrubbing and the liquid used for scrubbing Detergent, e.g. oil, punch height marked with 5: are the heat exchange surfaces shown, which are anchored in the detergent bunker area, with 6: is the entrance a medium to be heated, e.g. steam feed for heating in the heat exchange surfaces, shown, with 7: the exit from the Wärmetauschfläcben, with 8: the liquid pump to operate the spraying and washing device, with 9: the delivery from the sump of the Spray, washing tower and heat exchanger, e.g. for cleaning tar and other Pollutant-enriched predetermined washing load.

Durch diese erfindungsgemäße Vorrichtung entfällt der sonst erforderliche separate Hochdruckwärmeaustauscher, der für einen Wärmeaustausch von schmutzigen, aggressiven Heißgasen in der Regel in der Regel sehr problematisch ist.This device according to the invention eliminates the otherwise required separate high-pressure heat exchanger, which is used for heat exchange of dirty, aggressive hot gases are usually very problematic.

Selbstverständlich ist die Erfindung nicht auf die vorstehend im einzelnen dargestellten und beschriebenen Ausbildungsformen beschränkt, sondern es sind zahlreiche Abänderungen möglich, ohne jedoch von dem Grundgedanken abzuweichen, eine Vorrichtung zur Heißgaskühlung, Waschung und gewünschtem Wärmeaustausch so vorzusehen, daß der Sprüh- und Waschturm im unteren Bereich mit der erforderlichen Waschflüssigkeit gefüllt ist, und im Bereich der gebunkerten Waschflüssigkeit Wärmeaustauschflächen zur Abgabe der im Waschöl enthaltenden überschüssigen Wärme an ein Trägermedium, vorzugsweise Dampf, Wasser oder dergleichen, vorgesehen ist, wobei die abgeführte Wärme, z.B. in Dampfform, z.B. bei der Kohledruckvergasung, dem Wärmehaushalt innerhalb des Kohledruckvergasungsprozesses wieder zugeführt wird.Of course, the invention is not limited to the above in detail Forms of training shown and described are limited, but there are numerous Modifications possible without deviating from the basic idea, a device to provide for hot gas cooling, washing and the desired heat exchange so that the Spray and washing tower in the lower area with the necessary washing liquid is filled, and in the area of the bunkered washing liquid heat exchange surfaces to transfer the excess heat contained in the washing oil to a carrier medium, preferably steam, water or the like, is provided, with the discharged Heat, e.g. in vapor form, e.g. in the case of coal pressure gasification, the heat balance within of the coal pressure gasification process is fed back.
