AIR-GRAVITY ACCUMULATOR OF ELECTRIC ENERGY Russian patent published in 2024 - IPC F02C6/16 F01D15/08 F01D15/10 

FIELD: power engineering.

SUBSTANCE: technical solution relates to the field of solar and wind power engineering, namely to the air-gravity accumulator of electric energy. Device includes tanks made in the form of cylinders of first stage 1 and second stage 1a for compressed air with sealed cover 2, a generating installation of electric current 3 with a turbine, air lines, check valves 4, pressure reducer 5, piston compressor 6 connected by inlet air line to cylinder of first stage 1 through check valve 4, pressure reducer 7, water radiator 8, piston compressor 9. At that, pressure reducer 7, water radiator 8, piston compressor 9 are installed in series on the outlet air line of the cylinder of first stage 1, which is an inlet air line for cylinders of second stage 1a, connected to it through check valve 10. Cylinder 1 and water radiator 8 are equipped with discharge condensate valves 11 connected by main line with drip irrigation pump 12 through condensate tank 13. Water radiator 8 is connected to additional generator 14. Piston 15 with ballast 16 is installed inside each of cylinders 1 and 1a. Cylinders of the second stage are connected to electric current generating unit 3 by air line through electromagnetic valves 17 and pressure reducer 5. Pressure gauges 18 are installed on air lines. Cylinder cover 2 is equipped with air valve 19 for air outlet from above-piston space to prevent formation of vacuum or pressure.

EFFECT: improving operating reliability, reducing operating costs and improving environmental safety.
