Abstract
The invention discloses a novel high-temperature-resistant heat supply pipeline. The novel high-temperature-resistant heat supply pipeline comprises a steel pipe and an aerogel heat-insulating coating, wherein the outer side of the steel pipe is wrapped with the aerogel heat-insulating coating and then filled with polyurethane foam, and the outermost layer is a polyethylene sheath. The aerogel heat-insulating coating is introduced, and due to the good heat-insulating, waterproof and high-temperature-resistant performance of the aerogel heat-insulating coating, the overall heat transmission efficiency and durability of the pipeline are improved, and the energy loss is lowered.
Description
Technical field
The present invention relates to new material, calorifics and mechanology field, particularly relate to a kind of high temperature resistant new heat-supplying pipeline.
Background technique
Conventional heat supply pipeline is generally made up of steel pipe, thermal insulation layer and protective coating, and thermal insulation layer generally adopts polyurethane foam, mainly because its fabricating cost is cheaper, and lightweight, there is good thermal and insulating performance.Protective coating generally adopts polyethylene to make sheath, mainly utilizes its crushing resistance and serviceability and water-proof performance to give prominence to; Thermal insulation layer Main Function is the heat loss that minimizing heat supply pipeline and annex, equipment etc. occur due to heat exchange in Heat transmission process, with fuel saving, ensures heating quality.But, due to the narrow limitation of the heat resistance of polyurethane foam, when temperature reaches 120 DEG C, just there will be deterioration phenomenon, to such an extent as to lose function of heat insulation, therefore, at present in heating system, especially a pipe network, supply water temperature often can only control at 110 DEG C even lower, and its result causes that whole heating system heating range is little, heating efficiency is low exactly.
Summary of the invention

Summary of the invention
The object of the invention is to make up the deficiencies in the prior art, provide a kind of aerogel coating low heat conductivity, the characteristic such as high temperature resistant, form a kind of heat supply pipeline insulation composite structure.
The technical solution adopted in the present invention is: comprise steel pipeline and aerogel heat-proof coating, and additional polyurethane foam and outer protective polyethylene cover form a kind of composite pipe structure.Aerogel heat-proof coating is wrapped in outside steel pipeline, thickness only needs 1.5mm, when heat supply temperature is reached more than 150 DEG C, its surface temperature still can maintain less than 120 DEG C, thus realize improving a pipe network heat supply temperature, polyurethane foam can be kept again to be unlikely to aging, still can to play the effect of insulation.
Further, improve heat supply temperature, following several significant change can be brought: heating efficiency improves greatly, and heating range obviously expands.
Further, for realizing Winter heat supply from now on, cooling in summer integration provides the foundation condition.
the advantage that the present invention has:
1. need change existing heat supply pipeline structure, production technology only does fraction adjustment.
2. with low cost.
Accompanying drawing explanation
Fig. 1 is configuration schematic diagram of the present invention.
Embodiment
In order to make those skilled in the art person understand technical solution of the present invention better, below in conjunction with drawings and embodiments, the present invention is described in further detail.
As shown in Figure 1, outside steel pipeline 1, wrap up one deck aerogel heat-proof coating 2, play heat-blocking action.
Described steel pipeline 1, thickness 20-40mm, can bear the pressure of 1-5MPa.
Described aerogel heat-proof coating 2; it is a kind of novel thermal-protective material; thermal conductivity is low, high temperature resistant, waterproof; thickness only needs 1.5mm; available protecting polyurethane foam 3 can not produce deterioration phenomenon when pipe temperature reaches 150 DEG C; in figure, 4 is outer protective polyethylene cover, plays protection, resistance to compression and waterproof action to whole pipeline.
Above an example of the present invention has been described in detail, but described content being only preferred embodiment of the present invention, can not being considered to for limiting practical range of the present invention.All equalizations done according to the present patent application scope change and improve, and all should still belong within patent covering scope of the present invention.
