High-temperature cooler heat exchange tube bundle support device

Abstract

The invention relates to a high-temperature cooler heat exchange tube bundle support device which comprises a left cover plate, a bearing plate and a right cover plate. The left cover plate and the right cover plate are fixedly connected to the left side and the right side of the bearing plate; a gap is arranged between the left cover plate and the bearing plate, and a gap is arranged between theright cover plate and the bearing plate; the gaps are runners; and multiple pipe connectors are fixedly connected to the upper end and the lower end of the left cover plate and communicate with the runners. The high-temperature cooler heat exchange tube bundle support device provided by the invention has the advantage of avoiding tube bundle pull-dropping and shear fracture caused by support pipeplate overheating deformation.

Description

technical field [0001] The invention relates to the technical field of design and manufacture of heat exchangers, in particular to a support device for heat exchange tube bundles of high-temperature coolers. Background technique [0002] The high temperature gas cooler is the most important heat exchange system in the arc wind tunnel. Conventional industry standard U-shaped shell-and-tube heat exchangers usually have only one tube sheet, and cooling is not considered, and local reinforcement is not considered in the design of openings. For large-scale arc wind tunnel high-temperature gas coolers, this design type does not apply. The main reasons are as follows: First, the high-temperature cooler of the arc wind tunnel adopts the gas-sweeping tube bundle method, and it is necessary to consider suppressing the impact of the vibration of the tube bundle caused by the high-speed high-temperature air flow; The cooling design will produce large thermal deformation, which will ca...

Problems solved by technology

[0007] By adopting the above technical scheme, the cooling water is introduced from the pipe joint, and the cooling water flows through the supporting device along the flow channel, so that the supporting device has a water cooling effect, and the sandwich structure is used to make the structural strength of the supporting device higher, realizing replacement. The support and vibration suppression of the heat tube bundle, so as to solve the problem of insufficient strength of the support plate of the internal tube group after opening holes in the large-scale (diameter exceeding 2m, or cross-sectional area exceeding 2m×2m) high-temperature gas (over 6000K), easy deformation at high temperature, manufacturing Problems such as difficult process control in the process
