Description

[0002] Many pipelines and equipment in nuclear power plants operate under high-temperature conditions. To reduce heat loss from pipelines and equipment, ensure that the concrete wall temperature and thermal stress of the nuclear power plant meet design requirements, and improve the thermal economy of the power plant operation, it is necessary to cover the outer walls of high-temperature pipelines and equipment with insulation.

[0003] Due to the high radioactivity levels within nuclear power plants, the non-metallic insulation materials commonly used in industrial piping and equipment are unsuitable for use in nuclear power plants. This is primarily due to the fact that long-term irradiation can activate these materials, generating large amounts of radioactive dust and solid waste that pollute the environment and are harmful to humans. This also reduces their thermal insulation performance, shortening their service life and making it difficult to meet the 60-year service life requirement. Furthermore, in the event of a loss-of-coolant accident (LOCA) at a nuclear power plant, these non-metallic insulation materials can easily lose mass after being immersed in water, potentially clogging pit filters.

[0004] Currently, traditional metal reflective foils are square chocolate flower-shaped or corrugated. After overlapping, they have poor stability and consistency and are prone to shaking, which affects the heat reflection effect and the thermal insulation effect of the air layer, making it difficult to meet the thermal insulation requirements. At the same time, the connection between the insulation layers is achieved through non-adjustable buckles on the surface, usually fixed by spot welding or rivets, which makes the on-site installation extremely demanding on size, increasing the processing cost.

The upper and lower surfaces of the metal reflective foil 62 are spaced apart with convex bubbles 63 and concave bubbles 64. The metal reflective foil 62 is a very important thermal insulation component in the metal reflective thermal insulation component. The convex bubbles 63 and concave bubbles 64 are set, so that when the metal reflective foil 62 is stacked and fixed, the two adjacent layers of metal reflective foil 62 will be staggered, and a fixed gap will be formed between the two adjacent layers of metal reflective foil 62, which will slow down the natural convection of air between the foil layers and reduce heat loss. When overlapping and assembling, each metal reflective foil 62 and the folded edges 65 on both sides are welded and fixed to the corresponding side panels 5, which has the characteristics of good stability and consistency, can avoid shaking, and form a stable air insulation layer between the two layers of metal reflective foil 62, thereby improving The heat reflection and heat insulation effects, plus the hemispherical convex bubbles 63 and concave bubbles 64, can improve the heat dissipation range and meet the insulation requirements. Each group of convex bubbles 63 and concave bubbles 64 are arranged at equal intervals, which can improve the uniformity of heat reflection and heat insulation effects. The folded edge 65 is L-shaped, which is convenient for overlapping and assembling between each metal reflective foil 62, and improves the supporting strength. The height of the convex bubble 63 and the concave bubble 64 are equal to the height of the metal reflective foil 62 and the folded edge 65, and can contact the adjacent ray blocking plate 61 to further improve the supporting strength. In actual applications, the metal reflective insulation component can be widely used in occasions where insulation and heat reflection are required.
