Pressurized gas vortex cycle power generation system

Abstract

The invention discloses a pressurized gas vortex cycle power generation system, which relates to the field of heat energy power generation and comprises a heating area, a vortex gas storage area, a vortex generating device, a turbine, a generator, a cooling area and a pressure regulating valve which are connected in series through a pipeline, and a closed and communicated space is formed inside. And the pressure regulating valve can regulate the internal pressure. When the power generation system works, gas absorbs energy in the heating area, flows after expansion, enters the vortex generation device to form vortexes, and then acts on the turbine to enable the power generator to generate power; the residual kinetic energy of the gas can enable the gas to flow into the cooling area along the pipeline, and after being cooled, the gas enters the heating area and the vortex gas storage area under the action of the pump to form circular flow. According to the power generation system, pressurized gas serves as a working medium, the energy conversion efficiency is high, the limitation of terrains is small, arrangement is flexible, waste heat can be utilized, and more energy is saved compared with the prior art.

technical field [0001] The invention relates to a power generation system, in particular to a system in the field of generating electricity using thermal energy. Background technique [0002] In the current thermal power generation system, the working medium used is generally water. Since the specific heat capacity of water is relatively large, in the process of heating water, water will be vaporized into water vapor, absorbing a large amount of heat energy; During the condensation process, a large amount of energy is taken away by the cooling water; resulting in a very low efficiency of converting heat energy into electrical energy during the entire cycle power generation process, generally only about 40%.

[0002] In the current thermal power generation system, the working medium used is generally water. Since the specific heat capacity of water is relatively large, in the process of heating water, water will be vaporized into water vapor, absorbing a large amount of heat energy; During the condensation process, a large amount of energy is taken away by the cooling water; resulting in a very low efficiency of converting heat energy into electrical energy during the entire cycle power generation process, generally only about 40%

[0003] At present, some people at home and abroad are studying the use of tornado power generation, or the use of wind power generation, but because the density of the atmosphere is relatively low, in order to generate enough kinetic energy for power generation, it is usually necessary to provide relatively long blades in the wind power generation system Generally, it can be more than ten meters long, and the longer ones can even reach tens of meters. Corresponding and relatively high supports must be built, and the power generation is also limited by geographical conditions. It must reach a certain wind speed to build, and the output The electric energy is still unstable; although using tornado power generation is more efficient than pure wind power generation, but to achieve a relatively large power generation power, it is generally necessary to build a power tower of more than ten meters, or even hundreds of meters to generate vortices. It can be said that it takes up a lot of space
