Project Introduction
It is found that the medium and low temperature geothermal resources have larger reserves, wider distribution, shallower burial depth and more economical development. The temperature range is suitable for using supercritical CO 2 instead of water as heat transfer medium and working fluid. From 2014 to 2017, we gradually developed a set of terminal design methods for geothermal power generation system named "Deep Rock Rose", aiming at finding out the general strategy of suitable power generation for medium and low temperature engineering geothermal system (EGS). Supercritical CO 2 is used as the main working fluid in the system. It is the first attempt to replace the heat exchanger with the fluid mixing step. Compressor, jet pump, steam turbine, condensation and separation equipment are integrated through Catherine wheel to form a coherent and compact thermodynamic system. The system is designed with the heat and mass transfer attributes of supercritical CO 2 and related refrigerants, showing the potential to improve the efficiency of geothermal power generation.
Project Meaning
"Deep Rock Rose" brings the scope of application of supercritical carbon dioxide cycle into the basic research of low temperature section, promotes its rapid landing through School-enterprise cooperation, and opens the pioneer of water-saving thermal power plant transformation research by using fluid technology. It can promote large-scale carbon dioxide emission reduction and resource utilization, mitigate climate change, promote geothermal utilization and earthquake prevention and disaster reduction research, and improve the commercialization of carbon dioxide. Value, revitalize the industrial chain of carbon dioxide control, utilization and geological storage at home and abroad, guide the healthy transformation of energy industry through bionic design and influence public awareness
