Description

Technical Field

[0001] The present invention relates to the technical field of pipelines, and specifically to a tube bundle waste heat recovery device with an extended heating surface. Background Art

[0002] A tube bundle refers to a structural form that is closely connected to the cavity wall (such as by welding, expansion jointing, etc.), enabling the cavity wall to not only serve as a shell but also become the "fins" of the tubes, so that the heat absorbed by it can be transferred to the tube bundle by conduction, which reduces the effective temperature of the cavity, thereby reducing the heat loss at the cavity opening and also reducing the heat loss through the insulation layer. For a horizontally arranged absorber, after the tubes and the wall are connected, the natural convection channel along the inner wall upward is restricted, thereby relatively reducing the convective heat loss of the cavity to the outside.

[0003] The following problems exist:

[0004] 1. Existing tube bundle waste heat recovery devices cannot be fixed according to pipes of different sizes during use for efficient heat absorption.

[0005] 2. Existing tube bundle waste heat recovery devices cannot extract the absorbed heat for reuse during use. Generally, they are only used to prevent heat dissipation. Summary of the Invention
