Detailed Description
Referring to fig. 1 to 7, the present invention provides a carbon dioxide sequestration system in geothermal energy heat supply, comprising:
An air extractor 1 which extracts hot water or steam from a gas production well and inputs the extracted hot water or steam into a heating system 3 through a heat exchanger 2, the heating system 3 is input into each unit, and then the water which is not used is returned into the gas production well through a water return system 4;
