Technical field
The utility model is related to jet chimney heat insulation heat preservation energy-saving field more particularly to a kind of compound heat insulation steam pipes
Road.
Background technology
Jet chimney is one kind of heat distribution pipeline, is mainly used for the fields such as heating, ventilation, idle call vapour, factory steam.It steams
Steam pipe road has good mechanical performance and heat-insulating property, leads to the heat insulating work suitable for various hot water or cold water's high/low temperature pipelines.
Present jet chimney outer surface is thermally shielded place using direct using rock wool material or PIR materials at present
Reason.It is fine using the heat-insulated processing of rock wool or PIR materials but when relatively low for temperature in jet chimney, but for steam
When temperature is higher in pipeline, rock wool either PIR materials be in direct contact high-temperature pipe will occur in a short time embrittlement or
Charing, eventually forms powder, loses heat insulating function, heat insulation and preservation effect is bad, causes a large amount of wastes of the energy, while also making
The service life for obtaining pipe insulation material shortens, and repair is replaced more frequent.
Invention content
The utility model aims to solve the problem that the deficiencies in the prior art, and provides a kind of compound heat insulation steam pipeline.
The utility model to achieve the above object, using following technical scheme：
A kind of compound heat insulation steam pipeline, including the steam steel pipe, the high temperature resistant zinc rich primer that set gradually from inside to outside
Layer, nano-hole aerogel heat insulation felt, fire line winding binding layer, aluminium foil air bag reflection layer, PIR layers, enhancement layer, metallic jacket
And wearing layer.
The aluminium foil air bag reflection layer includes the air bag layer of internal layer and the aluminium film reflecting layer of outer layer.
The enhancement layer is glass layer.
The metallic jacket is that stainless steel oversheath or the metallic jacket outer wall are equipped with anticorrosive paint layer.
The wearing layer is multiple protrusions of circumference uniform distribution.
Reinforcing rib is equipped in the metallic jacket.
The utility model has the beneficial effects that：The utility model is thermally shielded heat preservation using composite construction, first uses resistance to height
The high nano-hole aerogel heat insulation felt of warm nature cools the temperature to 150 DEG C hereinafter, reuse the not high PIR layers of high temperature resistance, keeps away
Exempt from PIR layers and be in direct contact steam steel pipe to carbonize, the two combines, and heat insulation effect is good, reduces energy loss；Fire line is wound
Binding layer can tie up nano-hole aerogel heat insulation felt, make its density higher；Aluminium foil air bag reflection layer can be reduced
