Title:
地熱利用システム
Document Type and Number:
Japanese Patent JP6694632
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a geothermal utilization system that suppresses precipitation of a scale on pipeline through which geothermal fluid flows and a heat exchanger and other external facilities, at the same time prolonging a maintenance frequency for the pipeline, etc.SOLUTION: A geothermal utilization system 1 according to an embodiment includes: an air-water separation tank 2 that separates a geothermal fluid that has flown out from an outlet port 11a of a geothermal fluid extraction pipe 11 into geothermal water and geothermal steam, at the same time maintaining carbon dioxide partial pressure of the geothermal steam at a partial pressure value of deaeration suppression or higher; and an aeration tank 3 for aerating the geothermal water that has flown in from the air-water separation tank 2 through a check valve 21, thus deaerating carbon dioxide contained in the geothermal water.SELECTED DRAWING: Figure 1
