The top plate is serially arranged on the outer wall of the slag discharge pipe and is in sealing connection, the bottom end opening of the slag discharge pipe is exposed out of the through hole of the bottom plate, two end faces of the bottom plate are respectively in sealing connection with the upward inner pipe and the downward slag discharge pipe, and the opposite faces of the top plate and the bottom plate are respectively in sealing connection with the outer connecting pipe and the corrugated pipe to form an elastic compensation structure. The inner cavity of the compensation structure is separated from the slag falling cavity by the partition board, and the flexible heat insulation material is arranged in the inner cavity of the compensation structure, so that the compensation effect of the corrugated pipe is not influenced, and the thermal protection of the corrugated pipe is also formed. The invention adopts a full-sealing structure to connect the slag discharge pipe, no dust escapes when discharging slag, and the working environment is improved. But because the clearance of 2mm ~ 5mm has been reserved between baffle hole and the slag discharging pipe, and the baffle lid constitutes radial floating structure at the inner tube upper end mouth, in the use, the baffle can make radial floating along with the shake of slag discharging pipe to constantly rub inner tube upper end mouth and insulation material, the slag discharging pipe also can rub insulation material in the course of the work, insulation material will be destroyed to powdered and leak from the clearance between baffle hole and the slag discharging pipe, lead to this slag discharging pipe expansion joint's life can not very long.
