Abstract
A kind of high performance vapor utilidor, it includes a jet chimney for being used for steam conveying, aluminum silicate layer and rock wool layer are at least coated with the outside of the jet chimney, also applied between the aluminum silicate layer and rock wool layer and be formed with reflective glass film, and layered seal is carried out with foil sealing band outside aluminum silicate layer；The rock wool layer outer surface, which also applies, is formed with reflective glass film, and also carries out layered seal with foil sealing band outside rock wool layer；Thick flat glass-fiber-fabric is also wrapped on outside the rock wool layer, equally carries out layered seal with foil sealing band in the outside of thick flat glass-fiber-fabric；Finally color steel is coated in outermost layer；Applied in advance on the jet chimney outer wall and be formed with least one layer of reflective glass film；It is reasonable with structure composition, easy to install and use, good reliability, can reduce the thermal loss of jet chimney, hence it is evident that the features such as improving steam pipeline heat-insulation performance.
Description
Technical field
The utility model relates to a kind of high performance vapor utilidor, belong to pipeline heat-insulating technology field.
Background technology
With the extension of steam power plant's heat range of heat, the heat-insulating property of jet chimney increasingly seems important.Passed according to heat
The three kinds of approach passed：Conduction, radiation and convection current, traditional steam pipeline heat-insulation, which focuses on, to be improved on thermal insulation material, is such as increased
Insulation thickness, to increase the heat-proof quality of thermal insulation material；But by largely testing certification, heat-insulating property and the heat of jet chimney
There are sizable relation, particularly hot-air convection for radiation and hot-air convection；Jet chimney generally uses lightweight（Insulation
Cotton）The opposite material that can bear higher temperature of thermal insulation material, such as alumina silicate and rock wool, and be dominant in terms of rock wool thermal conductivity factor
Gesture, but the voidage of lightweight cotton insulation material is very high, is formed compared with strong convection passage, so that heat-insulating property can be influenced.
The content of the invention
The purpose of the utility model is to overcome the shortcomings of the prior art, and it is reasonable to provide a kind of structure composition, makes
With easy for installation, good reliability, the thermal loss of jet chimney can be reduced, hence it is evident that improve the high-performance of steam pipeline heat-insulation performance
Steam heat preserving pipeline.
The purpose of this utility model is completed by following technical solution, a kind of high performance vapor utilidor, it
Including a jet chimney for being used for steam conveying, aluminum silicate layer and rock wool layer are at least coated with the outside of the jet chimney, institute
Also applied between the aluminum silicate layer and rock wool layer stated and be formed with reflective glass film, and divided outside aluminum silicate layer with foil sealing band
Layer sealing；The rock wool layer outer surface, which also applies, is formed with reflective glass film, and is also carried out outside rock wool layer with foil sealing band
Layered seal；Thick flat glass-fiber-fabric, equally the outside foil sealing band in thick flat glass-fiber-fabric are also wrapped on outside the rock wool layer
Carry out layered seal；Finally color steel is coated in outermost layer.
As preferred：Applied in advance on the jet chimney outer wall and be formed with least one layer of reflective glass film.
The utility model belongs to improvements over the prior art, it has, and structure composition is reasonable, easy to install and use, reliability
It is good, the thermal loss of jet chimney can be reduced, hence it is evident that the features such as improving steam pipeline heat-insulation performance.
Brief description of the drawings
Fig. 1 is the axial segmentation hierarchy schematic diagram of jet chimney heat insulating material for external described in the utility model.
Fig. 2 is the sectional view of Fig. 1.
Embodiment
The utility model is described in detail below in conjunction with attached drawing：It is described in the utility model a kind of high shown in Fig. 1
Performance steam heat preserving pipeline, it includes a jet chimney 6 for being used for steam conveying, is at least coated in the outside of the jet chimney 6
There are aluminum silicate layer 5 and rock wool layer 4, also applied between the aluminum silicate layer 5 and rock wool layer 4 and be formed with reflective glass film 3, and in silicic acid
The outside of aluminium lamination 5 carries out layered seal with foil sealing band 7；4 outer surface of rock wool layer, which also applies, is formed with reflective glass film 3, and
In the outside of rock wool layer 4 also layered seal is carried out with foil sealing band 7；Thick flat glass-fiber-fabric is also wrapped on outside the rock wool layer 4
2, equally layered seal is carried out with foil sealing band 7 in the outside of thick flat glass-fiber-fabric 2；Finally color steel 1 is coated in outermost layer.
Applied in advance on 6 outer wall of jet chimney described in the utility model and be formed with least one layer of reflective glass film 3.
The utility model may finally carry out infrared heat energy reflection three times using reflective glass film 3, also reflective three times
Glass film 3+ aluminium foil layered seals, block rising hot gases circulation road, greatly reduce thermal loss, improve heat-insulating property.
