Embodiment Construction
[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0019] see Figure 1-4, a low-temperature layer geothermal heat insulation pipeline, comprising a liner body 1, the two ends of the liner body 1 are respectively fixedly connected with a first connector 2, a second connector 3, the liner body 1, the first The connector 2 and the second connector 3 are made of ceramic composite material, specifically SHS-self-propagating ceramic composite pipe. Because the original control pipe is smoother, the resistance duri...

The invention relates to the technical field of geothermal water exploitation, and discloses a low-temperature layer geothermal water heat preservation pipeline. The low-temperature layer geothermal water heat preservation pipeline comprises a lining pipe body, the two ends of the lining pipe body are fixedly connected with a first connector and a second connector respectively, and the lining pipe body, the first connector and the second connector are integrated. According to the low-temperature layer geothermal water heat preservation pipeline, an original pipeline is divided into the lining pipe body and a shell steel pipe, and then a vacuum environment is supported between the two layers of pipelines, so that no gas exists between the two layers of pipelines for heat conduction, the heat dissipation path of geothermal water through the pipelines is greatly reduced, and the temperature drop condition caused when the burial depth length is large is reduced; and meanwhile, a triangular frame is installed in the interior of a vacuum cavity, the wooden triangular frame has a good heat insulation effect, due to the fact that the buried depth of the pipeline is large, the pressure borne by the outer side of the shell steel pipe is gradually increased, and due to the triangular frame, the bearing pressure at the welding positions of the connectors and the shell steel pipe is effectively reduced.
Description
technical field [0001] The invention relates to the technical field of geothermal water exploitation, in particular to a low-temperature layer geothermal heat insulation pipeline. Background technique [0002] Geothermal resources are clean and environmentally friendly energy used as heat sources, water sources, and mineral resources. It exists in the form of high-temperature geothermal heat. It exists in the form of water vapor and water at a temperature of 90-150 ° C. . [0003] In the low-temperature geothermal section, since most geothermal water exploitation pipelines are steel pump pipes, a huge defect brought about by such pipelines is their high thermal conductivity. drop, resulting in heat loss and waste of geothermal resources. Contents of the invention [0004] Aiming at the deficiencies in the use of the existing steel geothermal water pipes proposed in the background technology, the present invention provides a low-temperature layer geothermal water insulat...
