Description

Technical Field

[0001] This utility model relates to the field of pipelines, and in particular to a high-efficiency, heat-insulating, and rapid steam transport pipeline. Background Technology

[0002] A pipeline is a device made up of pipes, pipe fittings, valves, etc., used to transport gas, liquid, or fluid containing solid particles. Usually, the fluid is pressurized by blowers, compressors, pumps, boilers, etc., and then flows from the high pressure point to the low pressure point in the pipeline. It can also be transported by the fluid's own pressure or gravity. Pipelines have a wide range of uses, mainly in water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering, and various industrial installations.

[0003] In current industrial production, many processes rely on steam as a heat source to provide users with a warm environment. However, the current steam transmission pipelines suffer significant heat loss during the steam transmission process, which affects the heating provided to users and reduces the efficiency of steam transmission. To address this issue, we propose a high-efficiency, heat-insulating, and rapid steam transmission pipeline. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency, heat-insulating, and rapid steam conveying pipeline to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A high-efficiency, heat-insulated, and rapid steam conveying pipeline includes a conveying steel pipe, the outer surface of which is connected to an insulation layer, the insulation layer including an aluminum foil reflective layer, a nanoporous insulation material layer, an aluminum silicate fiber felt layer, and a protective layer.

[0007] In a further embodiment, the outer surface of the aluminum foil reflective layer is connected to the inner wall of the nanoporous thermal insulation material layer, the outer surface of the nanoporous thermal insulation material layer is connected to the inner wall of the aluminum silicate fiber felt layer, and the outer surface of the aluminum silicate fiber felt layer is connected to the inner wall of the protective layer.

[0008] In a further embodiment, the protective layer includes a glass fiber reinforced layer and a high-density polyethylene layer, wherein the inner wall of the high-density polyethylene layer is connected to the outer surface of the glass fiber reinforced layer.

[0009] In a further embodiment, a model number is provided on the front of the insulation layer, and the back of the model number is connected to the outer surface of the insulation layer.

[0010] In a further embodiment, a temperature sensor is provided above the insulation layer, and the bottom end of the temperature sensor passes through the insulation layer and the conveying steel pipe in sequence and extends into the interior of the conveying steel pipe.

[0011] In a further embodiment, a pressure sensor is provided above the insulation layer, and the bottom end of the pressure sensor passes through the insulation layer and the conveying steel pipe in sequence and extends into the interior of the conveying steel pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This device utilizes the high reflectivity of the aluminum foil reflective layer to reflect the heat radiated outward by steam through the transport steel pipe, reducing radiative heat loss. The nanoporous insulation material layer contains numerous nano-sized micropores, restricting air flow within the micropores. Furthermore, the material itself has an extremely low thermal conductivity, significantly inhibiting heat transfer outward through thermal conduction. The aluminum silicate fiber felt layer, with its high temperature resistance and excellent thermal insulation properties, further blocks residual heat transferred through the first two layers, while enhancing the overall structural stability of the insulation layer. This, in turn, improves the insulation effect and transport efficiency. Attached Figure Description

[0026] The insulation layer 1 connects to the conveying steel pipe 5. The insulation layer 1 comprises, from the inside out, an aluminum foil reflective layer 9, a nanoporous insulation material layer 8, and an aluminum silicate fiber felt layer 7. The high reflectivity of the aluminum foil reflective layer 9 reflects the heat radiated outwards by steam passing through the conveying steel pipe 5, reducing radiative heat loss. The nanoporous insulation material layer 8 contains numerous nano-sized micropores, restricting air flow within these pores. Furthermore, the material itself has extremely low thermal conductivity, significantly inhibiting heat transfer outwards through heat conduction. The aluminum silicate fiber felt layer 7 possesses high temperature resistance and excellent thermal insulation properties.

The protective layer 6 is composed of a glass fiber reinforced layer 11 and a high-density polyethylene layer 10. The glass fiber reinforced layer 11 can enhance the tensile and impact resistance of the insulation layer 1 and prevent the insulation layer 1 from being damaged by external pressure. The high-density polyethylene layer 10 has weather resistance, corrosion resistance and moisture resistance, which can block external moisture and impurities from entering the insulation layer 1 and protect the performance stability of the inner insulation material.
