Title:
SYSTEM AND METHOD FOR ACHIEVING LOW-TEMPERATURE-DIFFERENCE MULTI-STAGE POWER GENERATION USING MEDIUM/DEEP-LAYER LOW-TEMPERATURE EARTH ENERGY
Document Type and Number:
WIPO Patent Application WO/2023/240775
Kind Code:
A1
Abstract:
The present invention relates to a system and method for achieving low-temperature-difference multi-stage power generation using medium/deep-layer low-temperature earth energy. The system for achieving low-temperature-difference multi-stage power generation using medium/deep-layer low-temperature earth energy comprises a ground source heat circulation and transmission system, a plurality of stages of power generation systems and a waste heat utilization system. A heat circulation pipeline is provided between an output end and an input end of the ground source heat circulation and transmission system, the heat circulation pipeline sequentially performs heat exchange by means of the plurality of stages of power generation systems and the waste heat utilization system, the plurality of stages of power generation systems and the waste heat utilization system are arranged in series, and the waste heat utilization system is arranged downstream of the plurality of stages of power generation systems; and the temperature difference between temperatures of heat conduction medium inlets of two adjacent stages of power generation systems ranges from 5℃ to 25℃. By means of the system for achieving low-temperature-difference multi-stage power generation using medium/deep-layer low-temperature earth energy in the present invention, the difference between the temperatures of heat conduction medium inlets of every two stages of power generation systems ranges from 5℃ to 25℃, and multi-stage power generation is performed using the relatively low temperature difference, such that the energy consumption density is relatively high, and the efficiency of power generation is high.
