Abstract

322,601. Wood, W. R. Oct. 29, 1928. Regenerators.- Relates to apparatus in which gases are passed over solids for heat exchange, chemical reaction, or dust separation, of the type comprising a rotary casing with radial chambers containing subdivided solid material acting as a permeable wall through which the gases pass in the direction of the axis of rotation, and consists in giving the subdivided material a movement in relation to the walls of the chambers. As shown applied to a regenerative air heater the rotor B is mounted on a shaft 9 in a casing divided into two parts, one part 3 having air inlet and outlet 5, 6 and the other part having inlet 7 and outlet 8 for waste gases. The rotor has perforated end walls and is divided by radial partitions 11 into a number of chambers 10 each subdivided into two communicating parts 18, 19 by plates 20 ending short of the outer and inner walls 12, 13 of the rotor. The loose regenerative material, which may be lathe cuttings, does not fill the chambers and during the rotation moves around the plates 20, dust being collected in chambers 21 formed by perforated partitions 22, from which it is exhausted by a pipe 26. Non- perforated portions 15 of the end walls and baffles 17 prevent short-circuiting of gas or air. The regenerative material is inserted through doors 23 in the casing 3 with which a door 24 on each compartment may be brought into register, and the material may be removed through doors 25 in the casing 4.
