Description

Technical Field

[0001] This application relates to the technical field of flue waste heat recovery, and specifically to a flue waste heat recovery cover. Background Art

[0002] The recovery of flue gas waste heat mainly converts the heat carried by the flue gas into usable heat through a certain heat exchange method. The flue gas hood of the waste heat boiler becomes the key to the efficient utilization of waste heat recovery.

[0003] For example, the Chinese utility model patent with the publication number "CN219433811U" discloses a waste heat recovery flue hood, which uses an inner lining and an outer cover to tightly wrap and insulate the heat insulation pad to prevent the heat insulation pad from being exposed and reduce its service life. And bumps are welded on the inner wall of the outer cover, which can not only cooperate with the inner lining to squeeze and fix the heat insulation pad, but also form an air layer between the outer cover and the heat insulation pad to enhance the heat insulation and heat preservation performance.

[0004] In the above patent, an air layer is formed between the outer cover and the heat insulation pad to enhance the heat insulation and heat preservation performance. However, in actual use, when maintenance, replacement and other work need to be carried out on the flue hood, it is easy to cause air leakage in the air layer, affecting the sealing effect of the air layer and resulting in poor heat insulation and heat preservation effects.
