City Heating Network with Aerogel Blanket
Heating pipe insulation material is one of effective measures for energy saving and emission reduction in our country city central heating, hot water and steam by heat generated through pipes to various heat users constitute the network.
The purpose of heat supply pipeline insulation is to reduce the heat loss of heat medium in the process of transportation, save energy, improve the economy and safety of the system. The role of the heat insulation layer is to reduce energy loss, energy conservation, improve economic efficiency, ensure the operation parameters of the media, to meet the requirements of production and life of users.
For the industrial insulation layer of high temperature medium pipeline, it can also reduce the temperature of the outer surface of the insulation layer, improve the working conditions of the environment, and avoid the occurrence of scalding accidents. Insulation pipe in some developed countries has become an advanced mature technology.
Over the past decade, China's heating engineering and technical personnel through digestion, absorption of this advanced technology, is promoting the development of domestic pipe laying technology to a higher level. Results ten years proved that compared with the traditional insulation pipe laying waste and overhead laying, silica aerogel insulation blanket pipe has the advantage of very prominent:
1, reduce the total cost of the project:
aerogel insulation felt pipe thermal insulation performance and the heat loss is only 25% of the traditional pipe, long-term operation can save a lot of energy, reduce energy costs.
2, has strong waterproof and corrosion resistance :
without attached trench, Aerogels can be directly buried underground or in water, the construction is simple and rapid, low comprehensive cost. At low temperature, it also has good corrosion resistance and impact resistance.
3, the service life of Silica Aerogel up to 20 years:
the correct installation and use of pipe network maintenance costs can be very low.
4, low heat loss, energy saving:
its thermal conductivity is 0.018W/m * k, much lower than other commonly used pipe insulation material, thermal insulation blanket effect increased by 3~8 times. Low thermal conductivity and low water absorption rate, changed the traditional trench laying heating pipeline "wear wet jacket", greatly reducing the overall heat loss of heating pipe, heating the heat loss is 2%, less than 10% of the international standard.
5, covers an area of small, fast construction, favorable environmental protection:
need not laying huge trench buried heating pipe, only the insulation pipe buried underground, thus greatly reducing the area, reduce the earth excavation amount above about 50%, reduce civil masonry and concrete amount 90%. At the same time, heat processing and on-site trenching in parallel, only the joint, can shorten the duration of more than 50%.
