Embodiment
[0019] Example: figure 1 It is a schematic diagram of the structure of the vacuum heat-insulated steam pipeline of the present invention. It can be clearly seen from the figure that the vacuum heat-insulated steam pipeline of the present invention includes a working steel pipe 1 and a steel outer protective pipe 2, wherein the working steel pipe 1 is inner sleeved on In the steel outer protective pipe 2, the outer surface of the working steel pipe 1 is covered with a layer of thermal insulation material 3, and the two ends of the working steel pipe 1 and the steel outer protective pipe 2 are sealed, and between the working steel pipe 1 and the steel outer protective pipe 2 A vacuum layer 4 is formed.
[0020] Further, the steel outer protective tube 1 is provided with a vacuum valve 5 to adjust the vacuum degree of the vacuum layer.
[0021] Specifically, the thermal insulation material layer 3 is a fiber material.
[0022] Preferably, the thermal insulation material layer 3...

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 [0001] The invention relates to the technical field of energy saving and environmental protection, in particular to a vacuum heat-insulated steam delivery pipeline. Background technique [0002] Due to the rapid development of China's economy, the consumption of energy is increasing at an alarming rate. The thermal insulation project of pipelines is an important measure to save energy, but it has not received due attention for a long time. According to preliminary estimates, the heat loss of China's thermal pipelines is about Accounting for 7.5-8% of the coal consumption of the entire heating system, China's current energy utilization efficiency is about 29%, which is about 10 percentage points lower than the world's advanced level. The waste of resources is serious. How to reduce the loss of heat and improve the effective utilization of heat has become a The key to energy saving and emission reduction. [0003] The conventional pipeline insulation method is...
