Description
Technical Field
The utility model relates to a thermal power plant pipeline, especially high temperature high pressure steam pipeline's insulation construction.
Background
In a thermal power plant, a large number of pipelines for conveying high-temperature and high-pressure steam exist, and if the steam supply pipelines are not effectively insulated, heat is greatly lost due to heat release.
Arrange one insulation cover outside steam pipe is present steam pipe's standard and join in marriage, traditional technology generally adopts soft thermal insulation material or high temperature resistant cement to carry out thermal-insulated heat preservation to the pipeline, the heat preservation effect is general, especially at the junction of insulation cover, because steam pipe's length is generally great, the insulation cover also needs the segmentation installation, current insulation cover causes the heat loss easily at the junction of each section, the regional grow of heat loss after using for a long time, the heat preservation effect of insulation cover also can reduce gradually.
Therefore, the existing pipeline heat insulation structure has the problems of poor heat insulation effect, easy heat loss caused by the connection part of the heat insulation structure and short service life.
SUMMERY OF THE UTILITY MODEL

The utility model has the advantages of better heat preservation effect, heat preservation structure's connection position is difficult for causing heat loss, life is higher relatively.
The technical scheme of the utility model: the heat insulation structure of the high-temperature high-pressure steam pipeline comprises a pipeline and a heat insulation sleeve arranged outside the pipeline; the heat-insulating sleeve comprises a soft heat-insulating layer and a hard heat-insulating layer which are sequentially arranged from inside to outside; the soft heat-insulating layer comprises a nano ceramic fiber wire heat-insulating layer and a glass fiber wire heat-insulating layer which are arranged from inside to outside; the hard insulating layer comprises a structure reinforcing layer and a hard shell which are arranged from inside to outside; both ends of the heat insulation sleeve are provided with heat collecting rings; and each heat gathering ring is provided with a connecting lifting lug.
In the heat insulation structure of the high-temperature and high-pressure steam pipeline, the heat insulation sleeve is connected with the connecting lifting lug in a matching manner through a screw, and the heat collecting ring is arranged at the connecting position; the heat accumulation ring enables the heat accumulation effect of the heat insulation sleeve at the connecting position to be better, and reduces heat loss.
In the heat insulation structure of the high-temperature and high-pressure steam pipeline, the heat collecting ring is made of a high polymer material.
In the heat insulation structure of the high-temperature and high-pressure steam pipeline, the hard shell is made of an aluminum plate or a hot-rolled galvanized plate.
In the heat insulation structure of the high-temperature and high-pressure steam pipeline, the structural reinforcing layer is formed by laminating double layers of hard iron wire nets.
In the heat insulation structure of the high-temperature and high-pressure steam pipeline, the nano ceramic fiber wire heat insulation layer and the glass fiber wire heat insulation layer are both in spiral winding structures.
Compared with the prior art, the heat insulation sleeve is provided with the heat insulation sleeve with a two-layer structure, the connecting lugs are arranged at the two ends of the heat insulation sleeve, the heat gathering ring is arranged at the connecting part of the connecting lugs and the heat insulation sleeve, the heat dissipation of the connecting part of the heat insulation sleeve is reduced by the heat gathering ring, and the heat storage effect is relatively better; the heat preservation cover includes soft heat preservation and stereoplasm heat preservation, and soft heat preservation plays the heat preservation and is strikeed the size change that brings with the absorption pipeline, and stereoplasm heat preservation cooperation soft heat preservation plays heat preservation and increase structural strength's effect, and the stereoplasm heat preservation still can provide from establishing for the fixed of connecting the lug moreover, and two kinds of heat preservation all set up two-layer and interval setting, very big promotion the heat preservation effect.
Therefore, the utility model has the advantages of better heat preservation effect, heat preservation structure's connection position is difficult for causing the heat loss, life is higher relatively.
Furthermore, the soft heat-insulating layer is formed by double-helix winding of ceramic fiber wires and glass fiber wires on the pipeline, and the two wire bodies have good heat-resisting and heat-insulating effects and are mutually copied, so that the whole soft heat-insulating layer has the advantages of light weight and corrosion resistance.
The structure reinforcing layer is formed by laminating two layers of hard iron wire nets, and the structure strength is higher.
