Abstract

1,203,286. Direct contact heat exchange between solids. CHARBONNAGESDE FRANCE. 8 Aug., 1967 [8 Aug., 1966; 23 Feb., 1967], No. 36428/67. Heading F4U. [Also in Division C5] A heat exchanger for effecting heat exchange between two granular solids of different sizes comprises a rotating tube 1 inclined at an angle a to the horizontal and divided into compartments by centrally apertured partitions 10, 11, 12, and is provided with perforated lifting vanes 15, 16, 17 which are so shaped and located that any line of intersection of a vane with a plane passing through the tube axis makes an angle of at least α with the tube axis. Small solids are fed in and large solids discharged at the top of the tube and large solids fed in and small solids discharged at the bottom of the tube. As illustrated in Fig. 9 the partitions are perforated and the vanes are provided with extentions 30, 31, 32, but the latter may be omitted and the partitions may be imperforate. The central apertures of the partitions may be of ovate cross-section, Fig. 1 (not shown), and successive vanes may be regularly or irregularly staggered about the tube axis, Figs. 11 and 12 (not shown). As illustrated in Fig. 13, the heat exchanger is used to carbonize coal by heat exchange with thermophore. Carbonized coal is withdrawn at 22 and passed over a sieve 28, thermophore from the sieve and from the lower end of the tube 1 being carried by an air stream in a line 25 to a fluidized bed reactor 26 for reheating prior to reintroduction to the tube 1 through a cyclone 27. Coke dust carried by the thermophore burns in the recirculation system to aid reheating. In a modification, Fig. 14 (not shown), the thermophore and coal from the heat exchanger are passed through a second heat exchanger to give increased heat conservation.
