The invention discloses a vacuum heat-insulating steam-conveying pipeline, which comprises a steel working pipe and an outer steel protecting pipe, wherein the steel working pipe sleeves in the outer steel protecting pipe, both ends of the outer steel protecting pipe are respectively sealed by a head-sealing plate so as to form a vacuum heat-insulating layer between the two pipes, the vacuum heat-insulating layer is communicated with a closed valve, a valve is arranged on the outer steel protecting pipe to adjust the vacuum degree of the vacuum layer, a heat-insulating material layer is made of a fibrous material, the heat-insulating material layer is made of heat-insulating glass wool, and an anticorrosive layer is smeared outside the outer steel protecting pipe. Multiple heat-insulating structures are adopted by the vacuum heat-insulating steam-conveying pipeline, and the first layer is the vacuum heat-insulating layer, so that the heat conductivity is reduced, and the energy consumption is reduced; the second layer is the heat-insulating material layer, so that the heat dissipation through convection is reduced; the vacuum heat-insulating steam-conveying pipeline has the advantages of reasonable manufacturing cost, convenience in installation and low maintenance cost, and the overall operating cost is lowered in the operating process.
Description
Technical field
The present invention relates to energy-conserving and environment-protective technical field, be specifically related to a kind of vacuum heat-insulation steam conveying pipe.
Background technique
Due to the high speed development of China's economic, the consumption of the energy increases just with surprising rapidity, the adiabatic heat-insulation engineering of pipeline is the important measures of energy saving, but do not obtain due attention for a long time, according to preresearch estimates, the thermal loss of Sinomania hydraulic piping accounts for the 7.5-8% of whole heating system coal consumption, China at present efficiency of energy utilization is about 29%, lower than advanced international standard about 10 percentage points, serious waste of resources, the effective rate of utilization how reducing the loss raising heat of heat becomes the key of energy-saving and emission-reduction.
Conventional pipe insulation method lays thermal insulating material outside pipeline, and conventional pipe insulation material has mineral wool, rock wool, glass fibre, microporous calcium silicate, urethane foam etc.Conventional heat preserving method has following shortcoming: the thermal insulation property of (1) these heat distribution pipelines and along with pipe laying mode (indoor, outdoor, trench, direct-burried etc.), weather conditions (snow by rainstorm, outdoor temperature, atmospheric moisture etc.), and the difference of environmental conditions (whether having etchant gas etc. in surrounding atmosphere) and greatly reducing; (2) after insulation layer thickness reaches certain value, then thicken thermal insulation layer, heat insulation effect does not significantly improve, but cost improves greatly along with the increase of insulation thickness.
With steam, hot water during current industrial enterprise produces, in the engineerings such as cities and towns central heat supplying, conveyance conduit one is wrapped up with glass cloth by hot fluid steel pipe frame Surgery therapy cover, the foaming of one high-density polyethylene external protective pipe, rigid poly urethanes is thermal insulation layer and hot fluid steel pipe composition, and triplicity becomes an entirety closely; Structure can play certain heat insulating effect although it is so, but in course of conveying, the loss of heat energy still has about 10% ~ 35%, and conveying radius also only has about 8km.
Summary of the invention
For overcoming the deficiency of steam conveying pipe Insulation in prior art, the present invention seeks to: a kind of vacuum heat-insulating energy-saving steam conveyance conduit is provided, for the technical problem such as solve that conventional insulation pipe radiation loss is large, cost performance is low and construction is too complicated.
In order to solve the problems of the technologies described above, the invention provides the energy-conservation conveyance conduit of a kind of vacuum heat-insulating steam, comprise working steel tube and steel jacket, be placed in wherein said working steel tube in steel jacket, the coated adiabator layer of described working steel tube outer surface, between described working steel tube and steel jacket, two ends sealing, forms vacuum layer between working steel tube and steel jacket.
Further, described steel jacket is provided with vacuum valve, regulates vacuum layer degree of vacuum.
Concrete, described adiabator layer is lamination coating.
Preferably, described adiabator layer is that heat insulation glass is cotton.
Further, described steel jacket external application anticorrosive coat.
Compared with prior art, the invention has the beneficial effects as follows:
1, present invention employs multiple-insulating structure, first is heavily vacuum heat-insulating layer, and air is heat conductor, and the existence of vacuum layer decreases the existence of heat conductor, reduces pyroconductivity, reduces energy consumption.
2, second is heavily adiabator layer, have employed lamination coating, itself has outstanding thermal insulation property, blocks heat loss through radiation, hinder gas molecule collision simultaneously, decrease heat loss through convection.
3, vacuum heat-insulation energy-saving thermal insulation steam pipeline system cost of the present invention is reasonable, and easy for installation, maintenance cost is low, reduces overall operating cost in process of being expert at.
