Title:
CIRCULATION TYPE GEOTHERMAL POWER GENERATION SYSTEM AND ITS CONSTRUCTION METHOD
Document Type and Number:
Japanese Patent JP2016098806
Kind Code:
A
Abstract:
PURPOSE: To provide a circulation type geothermal power generation system and its construction method capable of preventing bad influences such as exhaustion of neighboring spring at groundwater system near a geothermal storing layer and further avoiding some impurities in hot water or steam flowed from the geothermal storing layer during process of geothermal power generation against fastening to a device as scale.CONSTITUTION: This invention comprises an outer pipe buried in the underground that is closed at a location other than opening part at its ground side or near side so as to enable fluid to be heat exchanged with external geothermal heat at a bottom part and an area of several ten to hundred meters from the bottom part in an upward direction and an inner pipe arranged therein. Although the outer pipe and inner pipe were used for a spring well in the past, they may be arranged in the spring well pipe not used at present for the spring well.SELECTED DRAWING: Figure 1
