Method for increasing power generation output of compressed air storage power generation device and compressed air storage power generation device

摘要

PROBLEM TO BE SOLVED: To realize the compressed air storage generation with large output at low cost by increasing the power output with a difference in level between an air storage room and a liquid storage room being not large. SOLUTION: This equipment has an air storage room for having air compressed and storing it, a liquid storage room 2 located at a higher level than the air storage room 1, and a communication path 3 to communicate between the liquid storage room 2 and the air storage room 1. The work liquid 15 filled in the air storage room 1 flows up and down between the air storage room 1 and the liquid storage room 2 through the communication path 3 according to the amount of stored air and thereby the air is compressed with the pressure balanced with the static pressure of the work liquid. As for the work liquid 15, a suspension which is made by mixing fine powder of a high specific gravity made of barite, hematite, or other material which is in such a state that it may hardly precipitate by being added with a dispersing agent, a thickner, and an alkali agent, to bentonite mixed water is used.
