Abstract

The invention relates to the technical field of thinning pipe protection, in particular to a thinning pipe sheath. The thinning tube sheath includes a sheath body, an upper mounting plate, a lower mounting plate and a compensator. The upper and lower ends of the sheath body are respectively connected to the upper mounting plate and the lower mounting plate. The compensator is sleeved on the upper and lower mounting plates. On the outside of the sheath body, the compensator divides the outer side wall of the sheath body into an upper section of the sheath body and a lower section of the sheath body. The thinning tube sheath provided by the invention has sufficient expansion margin when it is heated and expanded during the operation of the boiler, and can freely expand upward and downward along the compensator without encountering resistance, thereby effectively preventing deformation of the thinning tube sheath , so as to effectively avoid the problem of exposed wear and tear of the tube row, reduce the impact on the flue gas direction, and improve the stability of the boiler unit operation.

Description

technical field [0001] The invention relates to the technical field of strainer tube protection, in particular to a strainer tube sheath. Background technique [0002] The boiler tail wall superheater pulls thin tubes, which need to be protected by tube sheaths. The original pipe sheath structure is made by butting two U-shaped plates. However, the pipe sheath of this structure will be heated and expanded during the operation of the boiler and will be severely deformed, resulting in the exposure of the pipe row, affecting the direction and flow rate of the flue gas, causing serious wear and tear of the front cladding wall, and affecting the stability of the unit operation. sex. Contents of the invention [0003] (1) Technical problems to be solved [0004] The object of the present invention is to provide a strainer pipe sheath, which solves the problem that the existing strainer pipe sheath is thermally expanded and deformed during operation, resulting in exposed wear ...
