Abstract

Wärmeaustauscher für den Einsatz in Kohlehydrieran­ lagen bei Drücken von 200 bis 700 bar und Temperaturen von 100 bis 500 °C mit einem in einem geschlossenen Druck­ behälter angeordneten Rohrbündel, mit rohrseitigem Ein- und Austrittstutzen für den Kohlebrei und/oder Kreisgas, mit mantelseitigen Ein- und Austrittstutzen für das wär­ meabgebende Kreisgas, bei dem die Innenrohre zwischen durch Rohrplatten abgeschlossenen Hauben angeordnet sind, und die Hauben durch Haubenstutzen mit den rohr­ seitigen Ein- und Austrittstutzen für den Kohlebrei und/oder das Kreisgas verbunden sind, mit folgenden Merkmalen:
a) Der Druckbehälter (1) ist aus niedriglegiertem Stahl (2,25% Cr, 1% Mo) mit Wanddicken zwischen 150 und 250 mm, vorzugsweise zwischen 180 und 220 mm, gefertigt; bei Außendurchmessern zwischen 1000 und 2500 mm.
b) Das Rohrbündel, bestehend aus den Innenrohren (4) und Schikaneblechen (13, 14) ist aus einem austenitischen CrNi-Stahl gefertigt, wobei die Innenrohre (4) Innendurch­ messer von 40 bis 60 mm bei Wanddicken von 2 bis 3 mm aufweisen.
c) Die Schikanebleche bestehen abwechselnd aus Ringblechen (13) und Scheiben oder Kreisabschnitten (14) mit Blechdicken von 12 bis 16 mm und sind an einer der Rohrplatten (5, 6) über Zuganker (15) befestigt.
d) Die Hauben (7, 8) sind als Halbkugeln ausgebildet.
e) Einer der Haubenstutzen (9) weist ein Dehnungsaus­ gleich-Zwischenstück (16) auf.
f) Die mantelseitigen Ein- und Austrittstutzen (17, 18) für das wärmeabgebende Kreisgas sind an den Mantelhauben (2, 3) angeordnet. Heat exchangers for use in coal hydrogenation plants were at pressures of 200 to 700 bar and temperatures of 100 to 500 ° C with a tube bundle arranged in a closed pressure vessel, with tube-side inlet and outlet nozzles for the coal pulp and / or cycle gas, with jacket-side inlet and outlet connection for the heat-emitting cycle gas, in which the inner tubes are arranged between hoods closed by tube plates, and the hoods are connected by hood nozzles to the tube-side inlet and outlet nozzles for the coal slurry and / or the cycle gas, with the following features:
a) The pressure vessel (1) is made of low-alloy steel (2.25% Cr, 1% Mo) with wall thicknesses between 150 and 250 mm, preferably between 180 and 220 mm; for outside diameters between 1000 and 2500 mm.
b) The tube bundle, consisting of the inner tubes (4) and baffle plates (13, 14) is made of an austenitic CrNi steel, the inner tubes (4) having an inside diameter of 40 to 60 mm with wall thicknesses of 2 to 3 mm.
c) The baffle plates alternately consist of ring plates (13) and disks or circular sections (14) with plate thicknesses of 12 to 16 mm and are attached to one of the tube plates (5, 6) via tie rods (15).
d) The hoods (7, 8) are designed as hemispheres.
e) One of the hood sockets (9) has an expansion compensation adapter (16).
f) The jacket-side inlet and outlet nozzles (17, 18) for the heat-emitting circulating gas are arranged on the jacket hoods (2, 3).
