Boiler pipe bundle deformation preventing device and using method and application thereof

Abstract

The invention relates to a boiler pipe bundle deformation preventing device and a using method and application thereof. The boiler pipe bundle deformation preventing device comprises a left side clamping plate assembly and a right side clamping plate assembly which are parallel to each other. The left side clamping plate assembly comprises a left outer side clamping plate, a right outer side clamping plate and a left middle side clamping plate. The right side clamping plate assembly comprises a right middle side clamping plate, a left inner side clamping plate and a right inner side clamping plate. Centers of plate bodies of the left outer side clamping plate, the right outer side clamping plate, the left middle side clamping plate, the right middle side clamping plate, the left inner sideclamping plate and the right inner side clamping plate are provided with a plurality of arc portions correspondingly, wherein the arc portions are parallel and are used for storing pipe bundles. Thedevice further comprises a series-connection pin plate. The left side clamping plate assembly is fixedly connected with the right side clamping plate assembly through the series-connection pin plate.The boiler pipe bundle deformation preventing device has the advantages of being reasonable in structural design, stable and reliable in performance and the like, displacement of single pipes of the pipe bundles can be controlled effectively, and the situation that due to mutual friction between the pipe bundles, the pipe wall is thinned, pipe burst is generated, and safety operation of a boiler is influenced can be avoided.

Description

technical field [0001] The invention relates to the technical field of preventing deformation of boiler tube rows, in particular to a device for preventing deformation of boiler tube rows and its use method and application. Background technique [0002] The heating surface tube row is the heating surface in the boiler that heats water vapor under a certain pressure into superheated steam under a corresponding pressure, which plays an important role in the overall boiler. In the field of boilers, the tube row anti-deformation device is mainly used for split screen superheater, high temperature superheater, high temperature reheater, low temperature reheater, low temperature superheater and low temperature economizer. By restricting the displacement direction of a single pipe in the pipe row, the chaos caused by the lateral displacement and the friction caused by the lateral and longitudinal displacements are effectively improved; by limiting the expansion position of the pipe...
