Problems solved by technology

However, the above-mentioned thermal insulation layer only uses materials with large thermal resistance to block heat transfer and reduce thermal conductivity. The range of internal and external temperature drop is very limited. It is suitable for nuclear power plants. The effect is extremely limited, the reason is that the temperature in these equipment and pipelines is very high, and the conventional insulation layer technology cannot achieve the effect of heat preservation, and some even cannot be used at all.

Embodiment Construction

[0016] The present invention will be described in detail below in conjunction with the accompanying drawings: As shown in Figure 1, the present invention is spliced ​​by at least two heat preservation plates 1, and is coated on the surface of the thermal vessel 2 and pipeline 3 of nuclear reactor. The heat preservation plate 1 is composed of inner and outer stainless steel sheets 4 to form a thin box body, and a reflective heat preservation filler 6 composed of at least two stainless steel sheets 5 is installed inside, as shown in FIG. 2 .

[0017] The thin box body insulation board 1 is at least one of a plane board and an arc board. FIG. 2 shows a structure similar to a plane board, and FIG. 4 shows a structure similar to an arc board. In other embodiments, it can be applied to a combination of the above two insulation boards 1 .

[0018] The thin box body insulation plate 1 shown in Fig. 2 is equipped with reflective thermal insulation fillers 6 composed of at least three c...

Abstract

The present invention relates to a metal heat-insulating layer for equipment and pipeline. It is made up by splicing at least two heat-insulating plate blocks, said heat-insulating plate block is a thin-type box body formed from internal and external stainless steel sheets, in the thin-type box body interior a radiation-type heat-insulating filling material composed of two stainless steel radiation sheets is mounted.

Description

technical field [0001] The invention relates to a metal insulation layer specially used for equipment and pipelines, especially a metal insulation layer for thermal equipment and pipelines. Background technique [0002] In the prior art, the structural composition of the insulation layer is mainly to assemble the same insulation material or different blanket insulation materials in the insulation shell, such as commonly used lightweight glass fiber, mineral wool or porous insulation materials. The commonly used thermal insulation shell is mainly made of glass fiber reinforced plastics. Most of these insulation layers are directly made into two halves of the insulation shell, which are specially used for the insulation of small valves and pipelines. For larger thermal equipment and pipelines, insulation plates are used to splice each other, such as the shell of large steam turbine generator equipment. Insulation layer installed on the body. However, the above-mentioned ther...
