U-shaped heat exchange tube supporting structure for photo-thermal power generation reheater

The invention discloses a U-shaped heat exchange tube supporting structure for a photo-thermal power generation reheater and relates to a reheater in a hairpin structure for solar photo-thermal power generation to solve the problem that in a large-diameter reheater, as the span without support in the tail part of a heat exchange tube is enlarged, the heat exchange tube vibrates severely to endanger the operating safety of equipment if an effective supporting structure is not adopted. The U-shaped heat exchange tube supporting structure comprises an outer arc-shaped plate, an inner arc-shaped plate, a plurality of straight pulling ribs and a plurality of vibration-proof structures, wherein the inner arc-shaped plate is arranged on the inner side face of an inner arc wall of a reheater elbow and is fixedly connected to the last baffle plate in the tail part of the reheater, the outer arc-shaped plate is arranged on the inner side face of an outer arc wall of the reheater elbow, and the plurality of vibration-proof structures are arranged between the inner arc-shaped plate and the outer arc-shaped plate; the straight pulling ribs which are fixedly connected to the vibration-proof structures and the last baffle plate in the tail part of the reheater are arranged between the vibration-proof structures and the last baffle plate in the tail part of the reheater, and the straight pulling ribs which are fixedly connected to the adjacent two vibration-proof structures are arranged between the adjacent two vibration-proof structures. The U-shaped heat exchange tube supporting structure disclosed by the invention is used for the photo-thermal power generation reheater.
