Description

Technical Field

[0001] The utility model relates to the field of pipelines, in particular to a novel telescopic heat-insulating cover for soft sealing of furnace pipes. Background Art

[0002] The top of a hydrocarbon dehydrogenation furnace is typically equipped with numerous furnace tubes that pass through it. As the furnace is started and shut down, the tubes expand and contract due to heat and cold. Traditional multi-layer ceramic fiberboard seals not only struggle to meet these dynamic sealing requirements due to their inherent lack of elasticity, but also, as the furnace operates over time, the ceramic fiberboard shrinks under long-term high-temperature conditions, resulting in a gradual deterioration in sealing effectiveness. A superior air barrier bag seal structure can overcome these shortcomings, but the primary material, high-temperature resistant sealing cloth, is expensive and often manufactured overseas, making it difficult to procure and supply.

[0003] As shown in the announcement number CN 218511525 U, a new type of telescopic heat-insulating cover for soft sealing of furnace tubes is disclosed, which includes soft sealing heat-insulating devices respectively arranged on the furnace tubes (10). The soft sealing heat-insulating devices include an outer heat-insulating layer (1), a cold-side air-blocking bag (2), and a hot-side air-blocking bag (3) wrapped around the furnace tubes (10) from top to bottom, wherein the cold-side air-blocking bag (2) is composed of glass fiber cloth or high-silica cloth and filled with high-temperature resistant fiber loose cotton, and the hot-side air-blocking bag (3) is composed of fiber cloth and filled with high-temperature resistant fiber loose cotton. The utility model relates to the field of pipelines, and specifically to an anti-deformation structure for heating furnace tubes. The advantages of the utility model are: 1. Since the loose cotton used has the characteristics of self-rebounding and replenishing, the situation of substandard sealing is avoided during the dynamic expansion and contraction of the furnace tube, and the combination of the cloth bag and the loose cotton can play a role in heat insulation.
