Document Type and Number:
Japanese Patent JP6596494
Kind Code:
B2
Abstract:
[Problem] To provide a geothermal heat exchanger which has a high thermal efficiency and with which it is possible to reduce the loss of heat to a non-geothermal field when hot water that has been heated deep underground is conveyed to ground level. [Solution] This geothermal electricity generating system is characterized by being provided with: a medium transfer pipe 20 which comprises a double pipe without an opening in a geothermal field S, and which has a descending region that causes a medium to descend, and an ascending region that causes the medium to ascend; a high-pressure recirculating pump 30 that feeds the medium to the medium transfer pipe 20; a vapor generator 41 which extracts vapor from the medium that has been heated by geothermal heat; a production well which is formed around the medium transfer pipe 20 and which receives geothermal water; a reinjection well which returns at least part of the geothermal water that has completed a heat exchange process; a gas-water separator 71 which includes at least one gas-water separator and which extracts vapor from the geothermal water; and an electricity generator 45 which generates electricity using the vapor.
