Abstract

The invention discloses a serpentine pipe hanging device for a narrow-gap coal economizer. A traditional hanging structure is difficult to manufacture, easy to crack in a bending position, difficult to meet a tolerance standard, high in manual technical requirements and high in physical and metal energy consumption; and when a boiler works, a pipe easily breaks away from the hanging structure, is easily frayed by a hanging plate, and easily explodes and stops accidentally. The serpentine pipe hanging device for the narrow-gap coal economizer comprises a group of transversely staggered serpentine pipes (3) and a group of hanging plates (4), wherein the hanging plates comprise wide hanging plates (5); the wide hanging plates are connected with narrow hanging plates (6); the wide hanging plates are connected with the narrow hanging plates in a welding way; and the hanging plates comprise a first hanging plate, a second hanging plate, a third hanging plate till an Nth hanging plate. The serpentine pipe hanging device for the narrow-gap coal economizer is applied to the serpentine pipe hanging device for a coal economizer of a narrow-gap boiler flue.

Description

Technical field: [0001] The invention relates to a serpentine pipe hanging device for an economizer used in a narrow gap. Background technique: [0002] It turned out that the old hanging structure was difficult to manufacture, the bending was easy to crack, and the tolerance was not easy to meet the standard. The technical requirements for the workers were high, and the energy and physical strength were high. Moreover, the pipes were easy to detach from the hanging when the boiler was running, and it was easy to wear with the hanging plate. , Prone to explosion tube shutdown accident. Invention content: [0003] The object of the present invention is to provide an economizer coiled pipe suspension device for narrow gaps. [0004] Above-mentioned purpose realizes by following technical scheme: [0005] An economizer serpentine tube hanging device for narrow gaps, which consists of: a set of serpentine tubes arranged in a horizontal staggered arrangement and a set of hang...
