Abstract
The invention discloses a metal compensator for a reinforced circulating fluid bed boiler. The metal compensator is formed by connecting two sets of corrugated pipe compensation structures through a middle connecting pipe. Each set of corrugated pipe compensation structure comprises an inner connecting pipe, an outer connecting pipe, a corrugated pipe and a loop. Gaps are reserved between the middle connecting pipe and the inner connecting pipes at the two ends in the axial direction, and the middle connecting pipe and the inner connecting pipes are arranged side by side. The outer wall of the middle connecting pipe and the outer walls of the inner connecting pipes are fixedly connected with opposite annular flanges correspondingly, and the opposite annular flanges are connected through the outer connecting pipes and the corrugated pipes, so that a corrugated pipe compensation structure is formed. The metal compensator is improved on the aspects that a plurality of reinforcing rib plates are arranged between the opposite annular flanges arranged on the outer wall of the middle connecting pipe and the outer walls of the inner connecting pipes as well as between the end surfaces of the annular flanges on the outer walls of the inner connecting pipes and the outer walls of the inner connecting pipes; a ring installed on the outer wall of the straight section of each corrugated pipe in a sleeving mode, the straight section of the corrugated pipe and the outer wall of the corresponding outer connecting pipe are fixedly connected to form a reinforced connector; reinforcing rods are arranged in troughs of the corrugated pipes; the corrugated pipes are formed by pressing multiple layers of sheets. The metal compensator for the reinforced circulating fluid bed boiler is high in structure rigidity and strength and long in service life.
