Title:
GEOTHERMAL HEAT EXCHANGER AND GEOTHERMAL POWER GENERATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/216238
Kind Code:
A1
Abstract:
[Problem] To provide a geothermal heat exchanger and a geothermal power generation device having high energy harvesting efficiency, by improving the flash rate. [Solution] A geothermal heat exchanger 1 is provided with an outer pipe 2 into which water is supplied from aboveground and an inner pipe 3 disposed inside the outer pipe 2, wherein the inner pipe 3 is provided with a gate valve 6 at a bottom part 4 thereof. High-pressure hot water is generated without being brought to a boil by heat supplied from a geothermal region to water injected into the outer pipe 2. This high-pressure hot water does not boil, flows into the inner pipe 3 when the gate valve 6 opens, is depressurized in a depressurization area 8, and is extracted aboveground after being converted into a gas-liquid two-phase flow.
