Geothermal water conveying heat preservation pipeline and method thereof

Abstract

The invention provides a geothermal water conveying heat preservation pipeline and a method thereof. The geothermal water conveying heat preservation pipeline comprises a plurality of water conveyingstructures, sealing structures and limiting structures. Each water conveying structure comprises a liquid conveying pipe, a vacuum chamber and a liquid conveying chamber. An interlayer of each liquidconveying pipe of a cylinder structure is internally provided with the corresponding annular vacuum chamber used for heat insulation and isolation. Each liquid conveying pipe is internally provided with the corresponding liquid conveying chamber of a cylinder structure. Each sealing structure comprises a gas valve and a sealing ring. One sealing ring abuts between every two adjacent liquid conveying pipes and is provided with the corresponding gas valve communicating with the corresponding vacuum chamber. Every two adjacent liquid conveying pipes are sealed through the corresponding limiting structure. Each limiting structure comprises a plurality of limiting rods, a fixing ring, a containing ring, a drive sleeve, a sealing cover, a drive rod and a gear. The geothermal water conveying heatpreservation pipeline and the method thereof have the advantages that the liquid conveying heat insulation effect is good, the pipeline mounting and dismounting efficiency is high, and the pipeline mounting quality is good.

Description

technical field [0001] The invention relates to the technical field of geothermal equipment, in particular to an underground hot water transportation insulation pipeline and a method thereof. Background technique [0002] Geothermal drilling is used for geothermal steam and geothermal water drilling. Geothermal energy is natural thermal energy extracted from the earth's crust. This energy comes from lava inside the earth and exists in the form of heat. Geothermal energy is a new clean energy. Through The underground hot water transmission insulation pipeline transports the geothermal water source or the oil of the oil bath heat exchange equipment to the thermal energy conversion equipment, and then generates electricity through geothermal energy, and converts geothermal energy into usable energy. Insulation performance also determines the utilization efficiency and quality of geothermal energy. [0003] However, the installation and disassembly of the traditional undergroun...

AI Technical Summary

Problems solved by technology

[0003] However, the installation and disassembly of the traditional underground hot water transportation insulation pipeline is not convenient and quick, the recycling efficiency of the pipeline is low during use, the sealing performance is poor after installation, and the insulation effect on the liquid is poor when the liquid is transported, resulting in a large amount of heat loss.
