Technical Field
The utility model relates to a heat supply pipeline prevents heat preservation of heat loss device technical field specifically is a novel combination formula stereoplasm heat preservation shell.
Background
In petrochemical plants, steam systems are important systems, which provide the required power, electricity, heat energy, process steam, etc. to the plants, and are organically combined with process systems and heat exchange networks to fully recover the waste heat in the process. The steam pipeline has higher energy quality, and if the heat insulation effect is not good, huge heat dissipation is caused, the economic benefit of an enterprise is influenced, and even the process requirement cannot be met. According to calculation, in the steam pipe network system, steam is generated from a steam source, and 5% -20% of heat is lost in the process of conveying the steam to a user through the pipe network, so that the oil refining cost can be continuously reduced by applying the efficient steam pipeline heat insulation structure.
At present, the conventional heat preservation of domestic petrochemical enterprises adopts materials such as composite silicate, composite aluminum silicate, glass fiber cotton or rare earth foam for heat preservation, the materials are soft heat preservation materials, the heat preservation effect is general, the heat loss is high, the appearance is purchased or decorated by aluminum plates, the pipeline is deformed due to external force or other factors after a long time, the pipeline is easy to fall off, the appearance aesthetic feeling and the heat loss are integrally influenced, and the heat loss is high.
SUMMERY OF THE UTILITY MODEL
The utility model provides a novel combination formula stereoplasm heat preservation shell for solve the heat preservation among the prior art device and all adopt soft insulation material, the heat preservation effect is general, and the heat loss is higher, and the pipeline warp because of external force or other factors appear in the time of having a specified duration, drops easily, leads to the great problem of heat loss.
In order to solve the technical problem, the utility model provides a following technical scheme: a working core pipe is arranged in the hard heat-insulation shell, and the hard heat-insulation shell is sequentially provided with a nano aerogel layer, a first anti-seepage film layer, a calcium silicate layer, a second anti-seepage film layer, a polyurethane foaming layer and a metal sheet protective layer from inside to outside.
Preferably, the metal sheet protective layer is a stainless steel protective layer or a color steel protective layer.
Preferably, the inner surface of the metal sheet protective layer is provided with a coating of chitosan or derivatives thereof.
