Title:
SEALED FLUID CIRCULATION DEVICE FOR COLLECTING STEAM UTILIZING GEOTHERMAL ENERGY
Document Type and Number:
Japanese Patent JP3948846
Kind Code:
B
Abstract:
PROBLEM TO BE SOLVED: To supply fluid from above the ground into a sealed fluid circulation device passed into the ground having geothermal energy and to form the fluid into a mixture of hot water and steam by use of the geothermal energy to provide clean steam from the mixture without directly using geothermal energy fluid present in a geothermal energy fluid storage layer under the ground.
SOLUTION: A water feed side upper flow passage 7, a water feed side lower flow passage 8, an entraining return flow passage 9 consisting of the exterior wall of a lower inner pipe 15 and the interior wall of a funnel-shaped entraining separation device 16, a rise side lower flow passage 10, and a rise side upper flow passage 11 passing inside the water feed side upper flow passage 7 are formed inside the device body 2 of a sealed fluid circulation device 1. Further, the water feed side upper flow passage 7 and a water feed part 3 are communicated and coupled to each other and the rise side upper flow passage 11 and a steam takeout part 4 are communicated and coupled to each other.
