Abstract
292,642. Hayward, E. Feb. 22, 1927. Solids, treating with gases.-In effecting reactions between solid materials and air or other gases under heat and pressure, the substantially dry powdered or granulated solid materials are continuously fed through an externally heated chamber in which they are subjected to the action of a circulating current of air &c. under pressure, it may be in countercurrent, the solid materials are continuously or periodically charged into the chamber and the solid and substantially dry reaction products continuously or periodically discharged therefrom, the air &c. being introduced into and discharged from the chamber independently of the solid materials and the solid reaction products respectively. Pressures of the order of 20 atmospheres and temperatures up to 450‹ C. may be employed. As shown in Fig. 1, the initial material is fed from a hopper 21 through a valve 22 into an intermediate chamber from which a conveyer 23 passes it through a second valve 25 into the reaction chamber 4 which is surrounded by a casing 7 which may contain molten lead and by a casing 8 containing gas burners 11. The valves 22, 25 may be adapted for automatic co-operation in the same manner as the valves 31 described below. A worm 16 conveys the material through the chamber 4 and air &c. under pressure is circulated therethrough, preferably in countercurrent to the material, by means of pipes 20, the air &c. leaving the chamber being recirculated, if desired, with addition of fresh gas. The solid reaction product is discharged through a valve 31 into an intermediate chamber from which a second valve 31 passes it to a chamber 38, the valves 31 being automatically operated from a cam shaft 33 in such manner that they are never both open at the same time. Residual gas from the chamber 38 is passed through a silencer 41.
