Abstract

The utility model discloses an initiative-heat-insulating steam pipeline, belonging to the technical field of pipeline heat insulation, and solving the problem of non-ideal heat-insulating effect of the existing heat-insulating device for a steam pipeline. The initiative-heat-insulating steam pipeline comprises a piping (1), wherein a solar silicon sol heat-absorbing coating layer (2) is coated on the outer wall of the piping (1); a transparent polyester fibre tube (3) is fixed at the outer side of the piping (1); an airtight cavity (4) is formed between the transparent polyester fibre tube (3) and the solar silicon sol heat-absorbing coating layer (2); a plurality of convex lenses (5) are arranged on the inner wall of the transparent polyester fibre tube (3); and the focuses of the convex lenses (5) are located on the solar silicon sol heat-absorbing coating layer (2). The initiative-heat-insulating steam pipeline disclosed by the utility model has the advantages of being simple in structure, elaborate in design, good in heat-insulating effect, and easy to be popularized and used.

Description

A kind of active thermal insulation steam pipeline

Technical field

The utility model belongs to the pipeline heat-insulating technology field, is specifically related to a kind of initiatively pipeline of heat insulation function that has.

Background technique

Steam line must be incubated in apart from course of conveying long, especially winter and north cold area, and the purpose of insulation is in order to reduce to greatest extent the heat loss in the course of conveying.Steam conveying pipe generally all is embedded in underground, undergroundly can not take up an area face, does not affect the appearance of the city and urban planning because be embedded in.At present, the device kind that is used for pipe insulation is a lot, common are with thermal insulating materials such as felt, perlite, rock wools pipeline is wrapped up.But the heat insulation effect of the heat preserving method of above-mentioned pipeline is all undesirable.

Summary of the invention

The purpose of this utility model is the undesirable problem of thermal insulation apparatus heat insulation effect that has steam line now in order to solve, and a kind of active thermal insulation steam pipeline is provided.

This active thermal insulation steam pipeline comprises pipeline, be coated with the COLLOIDAL SILICA PAINT FOR SOLAR APPLICATION layer on the outer wall of pipeline, the outside of pipeline is fixed with the transparent polyester fibre pipe, has closed chamber between transparent polyester fibre pipe and the COLLOIDAL SILICA PAINT FOR SOLAR APPLICATION layer, the inwall of transparent polyester fibre pipe is provided with some convex lens, and the focus of convex lens is positioned on the COLLOIDAL SILICA PAINT FOR SOLAR APPLICATION layer.

The utlity model has following beneficial effect:

The utility model in the arranged outside of pipeline the transparent polyester fibre pipe, the transparent polyester fibre pipe has adopted convex lens junction principle, it can be with the sunlight junction on the COLLOIDAL SILICA PAINT FOR SOLAR APPLICATION layer on the pipeline external wall, thereby maximization catches solar thermal energy.Because the transparent polyester fibre pipe is transparent material, thereby under the sun shines, the brilliance under the reflection of transparent polyester fibre pipe convex lens of the bright spot on the COLLOIDAL SILICA PAINT FOR SOLAR APPLICATION layer was taken the people by force, can play the beautifying city effect.Closed chamber between transparent polyester fibre pipe and the COLLOIDAL SILICA PAINT FOR SOLAR APPLICATION layer can play insulation and reduce surperficial heat loss.The advantage that the utlity model has simple for structure, deft design, high insulating effect and be easy to promote the use of.

Embodiment

Below in conjunction with Fig. 1 and Fig. 2 the utility model is described further:

This active thermal insulation steam pipeline comprises pipeline 1, be coated with COLLOIDAL SILICA PAINT FOR SOLAR APPLICATION layer 2 on the outer wall of pipeline 1, adopt said structure, COLLOIDAL SILICA PAINT FOR SOLAR APPLICATION layer 2 can effectively absorb the solar heat heat energy that shines above it, has simultaneously good water proofing property and weatherability.The outside of pipeline 1 is fixed with transparent polyester fibre pipe 3, has closed chamber 4 between transparent polyester fibre pipe 3 and the COLLOIDAL SILICA PAINT FOR SOLAR APPLICATION layer 2, adopt said structure, transparent polyester fibre pipe 3 has good impact resistance, therefore can be broken easily because of collision, simultaneously it have also that material is light, the advantage of excellent, super transparent, the superinsulation of easily carrying, good weatherability, daylighting; Closed chamber 4 can play insulation and reduce surperficial heat loss.The inwall of transparent polyester fibre pipe 3 is provided with some convex lens 5, the focus of convex lens 5 is positioned on the COLLOIDAL SILICA PAINT FOR SOLAR APPLICATION layer 2, adopt said structure, transparent polyester fibre pipe 3 has adopted convex lens junction principle, it can with the sunlight junction on the COLLOIDAL SILICA PAINT FOR SOLAR APPLICATION layer 2 on pipeline 1 outer wall, catch solar thermal energy thereby maximize.Because transparent polyester fibre pipe 3 is transparent material, thereby under the sun shines, the brilliance under the reflection of transparent polyester fibre pipe 3 convex lens of the bright spot on the COLLOIDAL SILICA PAINT FOR SOLAR APPLICATION layer 2 was taken the people by force, can play the beautifying city effect.The advantage that the utlity model has simple for structure, deft design, high insulating effect and be easy to promote the use of.

Claims

1. thermal insulation steam pipeline initiatively, comprise pipeline (1), it is characterized in that: be coated with COLLOIDAL SILICA PAINT FOR SOLAR APPLICATION layer (2) on the outer wall of pipeline (1), the outside of pipeline (1) is fixed with transparent polyester fibre pipe (3), has closed chamber (4) between transparent polyester fibre pipe (3) and the COLLOIDAL SILICA PAINT FOR SOLAR APPLICATION layer (2), the inwall of transparent polyester fibre pipe (3) is provided with some convex lens (5), and the focus of convex lens (5) is positioned on the COLLOIDAL SILICA PAINT FOR SOLAR APPLICATION layer (2).
