A multi-segment seal ring for rotary equipment of the type involving a relatively large-diameter rotary cylinder supported with its axis horizontal by one or more fixed housings, seals being employed between the cylinder and at least one of the housings. One problem in equipment of this type is the practical impossibility of manufacturing and maintaining the cylinder as a perfect cylinder and special sealing structures are typically employed to accommodate out-of-round conditions of the cylinder, an example of which forms the subject matter of copending U.S. application, Ser. No. 618,984, filed June 8, 1984, now U.S. Pat. No. 4,502,702. The present invention provides improvements in the configuration and sealing of the gaps that occur at the overlapping, radial interfaces between neighboring segments, particularly to the end of increasing the efficiency of the equipment by eliminating or at least minimizing packing of treated material in the gaps. |
