Description

Technical Field

[0001] This utility model relates to the field of steam energy-saving technology, specifically to a heat preservation structure. Background Technology

[0002] With the rapid development of global science and technology, competition among chemical production enterprises will intensify. Improving comprehensive energy utilization efficiency has become a crucial means for enterprises to enhance their competitiveness within the industry, attracting widespread attention. In the chemical production sector, improving equipment operating conditions and reducing ineffective energy losses play an indispensable role in the field of chemical energy conservation technology. Therefore, the research and development of projects to reduce ineffective steam losses is particularly important.

[0003] In chemical production processes, steam is widely used in various fields such as product separation, material atomization, catalyst decoking, and instrument heating. How to reduce energy loss during steam transportation has become an urgent problem to be solved. In the traditional styrene plant heating process, most of the heat tracing pipe insulation structures are composed of ordinary insulation cotton and an outer plastic protective layer. This insulation structure has poor temperature control and the root of the heat tracing pipe is exposed, resulting in a large amount of steam heat energy loss. Therefore, a new insulation structure is proposed, which sets a first base layer and a second base layer on the outside of the heat tracing steam pipeline, and finally wraps it with waterproof fiberglass cloth. This can reduce the heat energy loss of the heat tracing steam and improve the production profit of the plant. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides a heat preservation structure. By setting a first base layer and a second base layer on the outside of the heat tracing steam pipeline, and finally wrapping it with waterproof fiberglass cloth, the heat loss of the heat tracing steam can be reduced, and the production profit of the equipment can be increased.

[0005] The technical solution adopted by this utility model to solve its technical problem is a heat preservation structure, including a heat tracing steam pipeline, a first base layer, a second base layer and a waterproof fiberglass cloth. The outer surface of the heat tracing steam pipeline is provided with a first base layer, and the outer side of the first base layer is provided with first spring bandages at equal intervals.

[0006] The outer surface of the first spring bandage is provided with a second base layer, and the outer side of the second base layer is equidistantly embedded with second spring bandages, and the outer side of the second spring bandage is provided with waterproof fiberglass cloth.

[0007] By adopting the above technical solution, the first base layer and the second base layer are sequentially included outside the heat tracing steam pipeline to reduce steam heat loss. The setting of the first spring bandage and the second spring bandage can overcome the irreversible stretching of the insulation material caused by pipeline expansion.

[0008] Specifically, the first steel clips are equidistantly arranged on the outer side of the first spring bandage, and the first steel clips are fixedly arranged on the outer side of the heat tracing steam pipeline.

[0009] Specifically, the second spring bandage is provided with second steel clips at equal intervals on its outer side, and the second steel clips are fixedly installed on the outer side of the second base layer.

[0010] Specifically, both the first spring bandage and the first steel clip are made of galvanized metal.

[0011] Specifically, the first base layer is made of aluminum foil fiberglass cloth, and the second base layer is made of silica aerogel.

[0012] The beneficial effects of this utility model are:

[0013] (1) The heat preservation structure described in this utility model is designed to wrap the surface of the heat tracing steam pipeline with a first base layer that has the function of reflecting heat radiation, thereby reducing the heat loss caused by the diffusion of steam heat energy to the outside through heat radiation. The first base layer is wrapped with a second base layer that has a strong heat preservation effect, thereby achieving the purpose of reducing heat loss.

[0014] (2) In the process of adjusting the amount of steam used for heating, the pipeline will contract and expand due to temperature changes. The first spring bandage and the second spring bandage wrapped around the outer layer of the first base layer and the second base layer have good rebound characteristics. During the process of pipeline contraction and expansion, they can pull the first base layer and the second base layer together, effectively avoiding the damage to the insulation structure caused by the large contraction of the steam pipeline, and effectively avoiding the loss of heat energy.

[0021] The outer surface of the first spring bandage 4 is provided with a second base layer 5, and the outer side of the second base layer 5 is equidistantly embedded with second spring bandages 7, and the outer side of the second spring bandage 7 is provided with waterproof fiberglass cloth 8.

[0022] In use, the first base layer 2 and the second base layer 5 are sequentially included outside the heat tracing steam pipeline 1 to reduce steam heat loss. The first spring bandage 4 and the second spring bandage 7 can overcome the irreversible stretching of the insulation material caused by pipeline expansion.

[0023] For example, such as Figure 1 As shown, the present invention also includes a first steel clip 3 equidistantly arranged on the outer side of the first spring bandage 4, and the first steel clip 3 is fixedly arranged on the outer side of the heat tracing steam pipeline 1.

[0024] In use, multiple first steel clips 3 fix the first spring bandage 4 and the first base layer 2 to the outside of the heat tracing steam pipeline 1.

[0025] For example, such as Figure 1 As shown, the present invention also includes second steel clips 6 equidistantly arranged on the outer side of the second spring bandage 7, and the second steel clips 6 are fixedly arranged on the outer side of the second base layer 5.

[0026] In use, multiple second steel clips 6 secure the second spring bandage 7 and the second base layer 5 to the outside of the first base layer 2.

[0027] For example, such as Figure 1 , Figure 2 As shown, the present invention also includes the first spring bandage 4 and the first steel clip 3, both of which are made of galvanized metal.

[0028] When in use, the first steel clip 3 and the first spring bandage 4, made of galvanized metal, are not easily corroded.

[0030] When in use, the first base layer 2, made of aluminum foil fiberglass cloth, has the ability to reflect heat radiation, and the second base layer 5, made of silica aerogel material, has a strong heat preservation ability.

[0031] In use, the first base layer 2 is wrapped around the upper surface of the heat tracing steam pipeline 1. The first base layer 2 is fixed to the heat tracing steam pipeline 1 by a set of first spring bandages 4, and each first spring bandage 4 is fixed to the heat tracing steam pipeline 1 by a set of first steel clips 3. The spacing between the first spring bandages 4 is between 4-8cm, and the spacing between the first steel clips 3 and the first spring bandages 4 is between 4-10cm.

The spacing between the second spring bandages 7 is in the range of 4-8cm, and the spacing between the second steel clips 6 and the second spring bandages 7 is in the range of 4-10cm.

[0033] Finally, a layer of waterproof fiberglass cloth 8 is placed on the second spring bandage 7;

[0034] A first base layer 2, which has the function of reflecting heat radiation, is wrapped around the surface of the heated steam pipeline 1 to reduce the heat loss caused by the diffusion of steam heat energy to the outside through heat radiation. A second base layer 5 with strong heat insulation effect is wrapped around the first base layer 2 to further reduce steam heat loss. At the same time, the first base layer 2 and the second base layer 5 are fixed by a first spring bandage 4 and a second spring bandage 7 with elasticity, which effectively overcomes the defects such as increased joints and increased heat loss caused by irreversible stretching of the insulation material due to pipeline expansion. A waterproof fiberglass cloth 8 is wrapped around the outer surface of the second base layer 5. This material not only effectively prevents moisture from the external environment from penetrating into the insulation structure, but also has a certain protective effect on the integrity of the insulation structure.
