Description

Technical Field

[0001] The utility model belongs to the technical field of steam transportation, in particular to a heat pump steam transportation device. Background Art

[0002] Heat pump steam transportation is an efficient and energy-saving way of utilizing heat energy. Heat pump steam transportation realizes the conversion, enhancement and long-distance transmission of heat energy.

[0003] The heat pump steam transmission system mainly consists of a heat pump device, a steam generator, pipelines and a control system. In the heat pump steam transmission system, the heat pump device plays a core role. The heat pump steam can use solar energy resources to realize thermal energy conversion. The solar collector in the system absorbs solar energy and converts it into thermal energy. The heat pump uses this thermal energy to raise the heat to a high temperature level through processes such as evaporation, compression, condensation and expansion. In this process, the low-temperature working fluid absorbs the heat emitted by the solar energy in the evaporator and evaporates into gas. It is compressed by the compressor to increase the temperature and pressure. It enters the condenser with high temperature and high pressure, and transfers the heat to water or other media through heat exchange, thereby generating steam, which is then transported to where it is needed through pipelines.

[0004] The heat pump steam transmission pipeline is usually composed of an internal transmission pipeline with multiple layers of insulation material added on the outside, and then the transmission pipeline is placed inside a steel outer casing. When the transmission pipeline is heated during steam transmission, it will expand, and the pipeline stress between the transmission pipeline and the steel outer casing may easily lead to pipeline rupture or deformation.
