ELECTRIC POWER GENERATION DEVICE USING PNEUMATIC ACCUMULATORS Russian patent published in 2025 - IPC F03D9/17 F03D9/34 F03D1/04 F03D1/02 

FIELD: renewable energy.

SUBSTANCE: invention relates to renewable power engineering, in particular to devices for accumulation and generation of electric energy using pneumatic accumulators. Device comprises a power plant connected to an air compressor drive with a liquid cooling system. Compressor output is connected to pneumatic accumulators. Liquid cooling system comprises a heat exchanger which is connected through a system of pipelines containing the first pump to the input of a temperature-controlled reservoir for storing the heating liquid. Outlet of the temperature-controlled tank is connected through the second pump to the heat exchanger of the heating liquid, which is located on the outer surface of the compressed air supply nozzle to the horizontally located aerodynamic tunnel. Nozzle inlet is connected via central pipeline with pneumatic accumulators. Nozzle outlet is located along the axis of symmetry of the inlet part of the wind tunnel. Periphery of inlet part of wind tunnel is connected to atmosphere on one side, and on the other side it is adjacent to mixing chamber, length of which is not less than 10 times its diameter. Wind tunnel is coaxial. Mixing chamber adjoins the working part of the wind tunnel. Outer part of the wind tunnel consists of sections of cylindrical tubes of the same diameter, and the inner part of the wind tunnel consists of sections of cylindrical tubes of different diameters, which are connected by diffusers. Inside the cylindrical sections of the outer part of the wind tunnel, coaxially with the diffusers in the gaps between the sections of the inner part of the wind tunnel, there are axial turbines of the same standard size, each of which is connected to its own electric generator through a reduction gear. Transition cone is connected to the beginning of the first section of the inner part of the wind tunnel, and a diffuser is located at the outlet of the last section of the outer part of the wind tunnel.

EFFECT: simplified design due to use of identical turbines.
